The five major factors affecting the price of the redirection drum

The five major factors affecting the price of the redirection drum:First, reversing the roller bearing: the price difference between the genuine Hawalo bearing and the poor quality small factory bearing is several times. The quality of the bearing directly determines the life of the drum.Second, change the wall thickness of the drum: the domestic general board should consider the difference, the actual thickness of the 8mm steel plate is only 7.2mm. The user requested to change the wall thickness of the drum to 8mm. We need to purchase 10mm steel plate for the feeding to ensure the thickness of the reaming cylinder is 8mm or more after the processing.Third, change the drum roller shaft: the whole solid shaft and the medium indirect tube shaft, the price is very large. The quality of the take-up shaft is poor and it is a cut-off.The fourth structure: redirection of the connection between the drum shaft and the barrel, the direct welding connection and the connection of the hub bushing have a large difference in cost, the quality of the direct welding is too poor, and the redirecting roller is easy to break the shaft from the welding.Fifth Concentricity: After the redirection of the drum is completed, the outer circumference of the cylinder surface is machined to ensure the concentricity of the shaft and the cylinder.

How to solve the chain chain failure of the chain conveyor?

    With the rapid development of industrial production, the chain conveyor has been widely used. The chain conveyor has the characteristics of simple structure, convenient maintenance and long service life. It has been recognized by customers in practical production applications. However, the failure of any conveying equipment is inevitable, so how to solve the conveyor chain failure of the chain conveyor, let us take a look at it.    When transporting materials, the chain conveyor first sends out the operation signal, first jogs twice and then officially starts normally. After the chain conveyor runs for half a week, it stops, checks the scraper chain that has been turned over to the chute, and simultaneously detects The degree of tightness of the traction chain, whether it is beating, scraping, deviation, drifting chain, etc., no problem after no-load operation, and then load test operation.    When the chain conveyor is in operation, it is necessary to pay attention to the operation of the motor of the head of the conveying equipment. If the temperature of the motor rises and the noise increases, the inspection should be carried out carefully, the operation center should be reported, and the lowering funnel should be closed. Stop the inspection. When the chain conveyor is in operation, it should also pay attention to the lubrication condition of the head star wheel at all times. If the bearing lacks oil, it should be refueled immediately with the manual oil pump.    During the use of the chain conveyor, the operation of the chain belt should be paid attention to at any time. If the chain rail is adjusted in time, when the machine speed is slowed down, the funnel should be adjusted to prevent the material from being pressed. When the chain conveyor is running, attention should be paid to the unloading of the head funnel. If the nylon conveyor belt is found to block the material, the power switch should be cut off immediately, and the operation should be stopped to prevent the chain conveyor head funnel from blocking the chain. To check if the chain is too long, if it is too long, adjust the tail tensioning device. If the blade has a blade at the end or the chain wheel and the hopper are not flexible, the head and tail blade need to be removed; It is necessary to add thin lubricating oil to the chain conveyor chain wheel to make the chain plate wheel rotate; the third is to replace and process the inactive hopper to avoid the chain chain failure during the operation of the chain plate conveyor.    In addition, to ensure the normal operation of the chain conveyor, it is necessary to regularly check the equipment and equipment maintenance. After the chain conveyor is inspected, it must be strictly checked and accepted according to the acceptance criteria to ensure that the chain conveyor can be put into production in time after inspection. There is no failure in production.    Above, we understand the solutions and preventive measures for the chain conveyor chain failure, and are ready to ensure the smooth production of the enterprise.

How to determine the conveyor chain is scrapped?

Mechanical equipment plays an important role in the work, and the conveyor chain is one of the most important parts in the equipment. The plate chain is also a type of chain and also plays an important role. If the plate chain takes too long, it will cause such problems. Then how to judge the scrapping of the transmission line chain?The general rule of the plate chain is mainly judged from the following aspects: First, the operator should be clear that the wear value allowed by the plate chain is limited. Generally speaking, it cannot be higher than the diameter of the ring chain bar. Tenth. The second point is to see the degree of distortion of the main ring of the main chain of the plate chain. If it is greater than 10 degrees, it will be scrapped. Of course, this should start from the uncurved plane above the main ring. If the chain of the plate chain is used for a long time, cracks, bends, etc. will occur. If it cannot be removed after being excluded, it can no longer be used, and it is counted as scrap.Once there is a problem with the plate chain, it will cause a lot of trouble for production. Then we must do daily maintenance and maintenance in our lives, and strive to reduce equipment damage. Jin Hengli usually does this. First of all, when installing the sprocket on the shaft, make sure that there is no swing and inclination. When the same drive assembly is not used, the rotary shaft should be in the same horizontal plane. If there is deviation, it will be Let the professional technicians carry out the repairs.The tightness of the plate chain should be appropriate. It should not be too tight or too loose. If the chain is too tight, the power of the device will increase and the consumption will be excessive. If it is too loose, the device will easily jump or even be unchained. Chains that have been used for a long time should not be mixed with new ones to avoid impact when used and to break the chain.

What are the anti-static methods for safe use of metal mesh belt conveyors?

    In the metal mesh belt conveyor grounding electrostatic hazard prevention method, grounding is an effective and economical method. During the process, static electricity is generated by friction, induction, or conduction. If the charge accumulates on a metal device, a conductive product, or a person's body that is insulated from the ground, the accumulated charge will release the energy in one discharge. Such electrostatic discharges are the main cause of electrostatic hazards. The metal mesh belt conveyor control method is to ground all the objects and maintain a low grounding resistance, and the electric charge accumulated on the metal equipment, the conductive products or the human body is quickly dissipated to the earth to avoid metal mesh belt transportation. Machine electrostatic hazard accident.    Precautions for the safe use of metal mesh belt conveyors:    1. The metal mesh belt conveyor equipment should be started at no load. After the operation is normal, it can be loaded, and it is forbidden to start after loading.    2. After the metal mesh belt conveyor is turned on, it will be idle for 3~5min. Check whether the parts are normal. The net has no slack and slippage. If there is any adjustment, the M20 tightening bolts at both ends of the driven roller can be adjusted and locked. ;    3. The metal mesh belt conveyor strictly controls the conveying capacity of the equipment, prohibiting the use of overload, and causing premature failure of components;    4. The metal mesh belt conveyor checks whether the driving roller, the driven roller, the bearing housing, and the transmission sprocket (gear) have abnormal noise. If the tightness of the chain is slack, adjust the adjusting bolt of the motor board to measure the tension and tighten it. Add grease to the bearing housing and the chain once a week, and tighten the sprocket stop screw to prevent the sprocket from moving;    5. The metal mesh belt conveyor regularly inspects the mesh belt bracket, the idler roller, the motor, the bearing seat and the connecting bolts of various parts, and finds that the looseness is timely tightened.

How can we extend the service life of flexible chain conveyors?

    Nowadays people are very efficient, and the same equipment, low efficiency will be eliminated. Flexible chain conveyors are now very popular and have a good market. However, many bosses also hope that the flexible chain conveyor has a longer use time, so that it will not lose money, which requires more maintenance, and no mistakes in operation. So how can we extend the service life of the flexible chain conveyor?    1. Check whether the joints of the flexible chain conveyor are normal, whether the screws are tight, and the looseness is found to be treated immediately.    2. Pay attention to the condition of the traction chain at all times during operation. When the tightness changes, adjust the tensioning device to return to normal.    3, pay attention to the use of lubricating oil between the various equipment, the reducer should be replaced with new lubricant after 7-14 days of use, and can be replaced after 3-6 months according to the actual situation.    4, the operation should be regular, the feeding is evenly guaranteed within the scope of control, it is forbidden to stop or start under full load conditions, and can not drive back.    We also need to cooperate with the daily operation and maintenance according to the instruction manual of the flexible chain conveyor, so as to extend the service life of the flexible chain conveyor.

The role of PP plastic chain plate in food conveyor

    With the continuous improvement of China's market economy level, various food industry enterprises have become more extensive in order to increase production demand. As one of the accessories in food conveyor equipment, PP plastic chain board has more advantages and better development prospects.    The PP plastic chain plate has high transparency and good circulation performance. As a new type of polymer material, PP plastic chain plate has special high wear resistance, tear resistance, high elasticity, high load bearing and other excellent performance. With the continuous promotion and development of food industry enterprises and civilian use, the lines are made. In order to improve the production capacity of the products, various industries have successively adopted PP plastic chain conveyor belts for production operations, in order to replace the traditional conveyor belts.    PP plastic chain conveyor belt not only has the advantages of traditional plastic mesh belt, but also has the characteristics of low density, corrosion resistance, etc., and can better improve the performance of food conveying machinery and equipment, so that it is better. The invention enhances the toughness of the conveying device, and can reduce the impact force and wear resistance of the material on the food conveyor and the drum when producing the transportation material, and has better earthquake resistance and wear resistance.    Compared with other mesh belts, PP plastic chain plates have the characteristics of high production efficiency and low cost, which can save the production cost for food production enterprises, and the cost is only one tenth of the stainless steel mesh belt.

How to avoid the dryness of the flexible chain conveyor during the turning process?

     When the flexible chain conveyor is turning, it is actually possible to select the ultra-high molecular weight polyethylene wear strip when selecting the wear strip. His wear resistance is several times that of the ordinary wear strip. This is because the flexible chain plate When turning, the two sides of the shaft are tightly attached to the wear strip, so that we can achieve our turning effect.     When conveying straight and turning, we can observe that in order to avoid dryness when turning the conveyor, the span between the chain plate and the chain plate will be very large with the guardrail. The flexible chain conveyor is more suitable for conveying. Light-loaded products such as beverages, toilet paper, etc., when the flexible chain conveyor is transported, if the difference between the width of the material and the standard width of the chain plate is large, the guiding member can be used to guide and restrain the material to achieve the transportation of materials of different sizes.

Drive mode design of chain conveyor

The chain conveyor is a conveying mechanism driven by an electric motor, and its conveying member is a chain plate, and the transmission mechanism transmits power to the conveying member.At present, there are two basic transmission forms of chain conveyors, one is sprocket chain transmission, and the other is direct coupling transmission of RV reducer.The chain conveyor has large load capacity, stable transportation and good material adaptability. It is widely used in heavy industry, automobile manufacturing, parts sorting and other fields.In general, there are some problems with the conveyor of the plastic chain plate, and if there is a problem, it needs to be dealt with immediately. Otherwise, the use of the device will become very unfavorable. Especially the plastic chain conveyor for the speed reducer, what are the requirements? Do a good explanation in the future.The neural network of the original plastic chain conveyor will vary depending on the way the neurons are linked. If the middle layer is composed of several layers, each layer of neurons can only receive the output of the previous layer of neurons. In the mutual connection network, any two neurons can be connected, and the input signal needs to be repeatedly transmitted and reciprocated between the neurons. If the change is several times, the plastic chain conveyor tends to be in a state of no disorder or enter the cycle. Shock and other conditions.The interface that provides the sensor device changes before it has failed. Therefore, the plastic chain conveyors of different working faces use reducers and different motor models. It is also necessary to fully determine the position of the reducer sensor device after the investigation. Due to the special environment in which the plastic chain conveyor of the working surface is located, the sensor can not prevent collision or damage. In order to ensure the damage of the sensor, sparks are generated, which will generate explosive gas and cause environmental explosion. The power supply and signal transmission from the sensor must meet the requirements.On the plastic chain conveyor, when the detailed operation, the reducer will definitely be used, and the use of the reducer, especially the conveyor such as the plastic chain plate, the speed reducer can often play a good role. . Therefore, there must be some requirements for its use, in order to be better to use.

Ready.    2, see if there are people, if there is someone on the plastic top chain, do not boot, look at its switch there is no problem, first idle for a while, the interlock can not be removed, if you remove it before booting is not safe.    3. After the operation is stopped, the plastic roof chain should be in a state of being emptied, and there is no object to be transported on it. If it is in use, it will suddenly stop, which will damage the machine.    4. When using, many parts such as the motor and the first tail wheel should be regularly tested. There is no need to lubricate the plastic top chain, and the sound is normal.

Do you knnow the basic information and maintenance of stainless steel chain plates?

   We will give you more information about the basic information and parameters of the classification of the chain plates on the water line. The classification of the conveyor chain plates has been mentioned in the past few days. There are many, we try our best to make each series Each model is analyzed, but we mainly focus on the analysis of some of the more types of chain plates used in the usual conveyor equipment. The purpose of this is to make everyone have a very good chain line product for the conveyor line. Intuitive feelings.    The classification of stainless steel chain plates can be carried out according to the shape and application range. According to the shape, we can divide them into: non-punched stainless steel chain plates, punched stainless steel chain plates, and raised stainless steel chain plates.    The main materials of stainless steel chain plates are: carbon steel, 1cr13 stainless steel, 316 stainless steel, 304 stainless steel, 201 stainless steel.    Stainless steel chain plates are widely used, mainly in the production of frozen food, food processing industry, dehydrated vegetables, glass products and other products.    There are some faults in the process of installation and use of stainless steel chain plates. Below our technicians use some exclusion methods for some common fault problems to analyze for everyone:    1: If the chain transmission type stainless steel chain plate has jump chain and is unstable, check whether the sprocket at both ends of the drive shaft is synchronized and whether the tooth end is excessively worn.    2: If the stainless steel chain plate is shaken, check whether the conveyor and the roller in the conveying tunnel have rust and refuse to turn, and adjust them one by one.    3: If the stainless steel chain plate appears to be biased, the tensioning shaft at one end of the driven shaft should be adjusted slowly. Remember to adjust quickly and cause the edge of the chain to be scratched.

What should be paid attention to in the purchase chain?

     There are a lot of things to pay attention to when buying a chain. Many professionals are not very familiar with the method in the purchase chain. There are actually many functions in the chain. Look at what is in the chain. Pay attention to things?     The appearance of the chain is detected whether the inner/outer chain is deformed, cracked, embroidered; whether the pin is deformed or rotated, embroidered; whether the roller is cracked or broken. Excessive wear; whether the joint is loose or deformed; whether there is abnormal sound or abnormal vibration during operation, and the chain lubrication condition is good.     The detection method of the chain is to measure the front chain after cleaning; the chain to be tested is placed on the two sprockets, and the upper and lower sides of the tested chain should be supported; the chain before the measurement should be under the condition of applying the three-point minimum tensile load. Stay 1 min; when measuring, apply the specified measurement load on the chain to tension the upper and lower chains. The chain should ensure normal toothing on the sprocket; measure the center distance of the two sprocket wheels.

What are the four major mechanical devices for belt conveyors?

The belt conveyor is a modern automation equipment, mainly through the development of automatic control, digital, networked controllers and sensors to achieve the delivery of various materials. The assembly line generally includes a traction member, a carrier member, a driving device, a tensioning device, a redirecting device, a support member, and the like. The belt conveyor can also be used to form a space conveyor line, which is generally fixed. The belt conveyor has a large conveying capacity and a long transportation distance. It can also complete several process operations simultaneously in the conveying process, and is widely used.    The four major devices of the belt conveyor are the drive unit, the brake unit, the brake unit and the reversing unit. We will give a detailed introduction below. The first is the drive unit, which is undoubtedly the core of the entire belt conveyor. It has just been mentioned that the working principle of the belt conveyor is mainly realized by the friction transmission force, and the friction between the belt and the drum is generated by the motor and the speed reducer. The function of the drive device is to transmit friction to the conveyor belt, which in turn affects the transmission distance and the transport direction.    Common brake devices include roller backstops, belt backstops, and tile brakes. This is a flexible addition based on the actual needs of the user. Its main function is to prevent the conveyor belt of the inclined upward movement from moving under the action of the cargo weight, causing the material to flow backward. Therefore, we say that the brake device under the belt conveyor parameters is very intelligent, especially suitable for material conveying at large dip angles.    The belt conveyor is continuously and smoothly operated according to the friction transmission principle. When purchasing the belt conveyor, the customer will have a detailed understanding of the belt conveyor parameters according to the production needs of the relevant enterprises. Belt width, conveying length, conveying speed and conveying volume are all closely related to the belt conveyor parameters. The production capacity of the equipment is different depending on the parameters.    Next we will talk about the tensioning device, which is divided into horizontal tension and vertical tension. The function of the tensioning device is to maintain the necessary initial tension of the conveyor belt to avoid slipping on the drive drum and to ensure that the sag of the conveyor belt is within the specified range. This is also to ensure the balance and continuity of the transfer process. The fourth important device of the belt conveyor, which we can see very clearly on the belt conveyor picture, is a roller set. The reversing device is generally at the end of the belt conveyor, and the belt is transported at different angles to reduce the transport pressure of the belt. The angle of the redirecting device is closely related to the diameter of the drum and needs to be adjusted on site according to the specific situation.
