A variety of causes and solutions of Teflon conveyor belt deviation

A variety of causes and solutions of Teflon conveyor belt deviation published on

Teflon conveyor belt deviation is often seen in the process of using, it is easy to cause the production process can not be normal produced, Here are some common reasons and solutions of conveyor belt deviation.

1.Tension adjustment
Conveyor belt tension adjustment is a very important part of the dryer deviation adjustment. The two change drums at the top of the heavy hammer except should be perpendicular to the direction of the length of the conveyor belt, it also should be perpendicular to the vertical line of gravity, that is to ensure the axis of the centerline level. When tension is applied with screw or hydraulic cylinder, the two housings of the tensioner drum should be translated simultaneously, to ensure that the drum axis and the conveyor belt vertical direction perpendicular. The adjustment method of specific conveyor belt deviation is similar to the adjustment of drum.

2.The Influence of the transfer point blanking position for conveyor belt deviation
The transfer point blanking position has good impact for conveyor belt deviation, especially in the two conveyor belt machine in the horizontal plane of the projection into a greater impact when the vertical. Generally, the relative height of the two conveyor belts at the upper and lower loading points should be considered. The lower the relative height, the greater the horizontal velocity component of the material, the lateral impact of the lower belt conveyor is also greater, and materials are also difficult to center. So that the material in the conveyor belt cross section deflection, eventually leading to conveyor belt deviation. If the material is skewed to the right, the conveyor belt run to the left. In the design process should be as much as possible to increase the relative height of the two conveyor belts of machine. The width of the general guide groove should be about two-thirds of the conveyor belt width is better. In order to reduce or avoid the conveyor belt deviation can increase the block material, change the direction and location of the material falling.

3.Adjusting the deviation of the belt conveyor in the bidirectional running conveyor
The adjustment of the bidirectional running conveyor belt is much more difficult than one-way conveyor belt, in the specific adjustment should first adjust a direction, and then adjust the other direction. To carefully observe the conveyor belt movement and the relationship between the trend of deviation, adjust one by one. Emphasis should be placed on the adjustment of the drive roller and the change-over roller, and then adjust the roller and the material of the blanking point. At the same time should pay attention to the conveyor belt in the vulcanized joints should make the conveyor belt section of the force in the length direction uniform, In the use of chain traction, the force on both sides should as much as possible same.

4.Adjust the load roller group
The deviation of conveyor belt in the middle of the whole conveyor can be adjusted through adjust the deviation of the roller group position. At the time of manufacture, the mounting holes on both sides of the idler group are machined into elongated holes for adjustment. The specific method is the conveyor belt which side of the deviation, which side of the roller group conveyor belt forward direction forward, or the other side is moved backward. The conveyor belt upward deviation, than the roller group of the lower position should be moved to the left, the upper position of the roller group is moved to the right.

5.Install the aligning roller group
Aligning roller group has a variety of types such as the intermediate shaft type, four-link type, vertical roller type, The principle is to use the block or roller in the horizontal direction of the rotation or blocking the lateral thrust of the conveyor belt to the conveyor belt to achieve the purpose of automatic belt deviation. Generally, when the total length of the belt conveyor is short or when the belt conveyor is running in both directions, it is reasonable to adopt this method. The reason is that shorter belt conveyors are easier to run off and not easy to adjust. But the long size belt conveyor is best not to use this method, because the self-aligning roller group will have a certain impact on the conveyor belt service life.

6.Adjust the drive roller and the repositioning roller position
The adjustment of the driving roller and the rewinding roller is the important link of the conveyor belt deviation adjustment. Since a belt conveyor has at least two to five rollers, all drums must be mounted perpendicular to the center line of the belt conveyor in the length direction, if the deviation is too large deviation must occur. The adjustment method is similar to the adjustment of roller group. For the head drum, such as the conveyor belt to the right side of the drum deviation, the bearing on the right should be moved forward. Conveyor belt to the left side of the drum deviation, the bearing on the left side should be moved forward. Correspondingly, the left bearing block can also be moved backward or the right bearing block is moved backward. The adjustment of the tail roller is the opposite to the head roller. After repeated adjustment until the conveyor belt transferred to a more ideal location. It is advisable to accurately position it before adjusting the drive or steering rollers.

7.How to deal with the deviation of conveyor belt
Conveyor belt deviation is the most common fault in conveyor running. In order to solve this kind of failure, the most important is to pay attention to the installation of dimensional accuracy and routine maintenance. There are many reasons for deviation, so need to be treated differently according to different reasons.

How to deal with the use of Teflon mesh belt with the case of slipping

How to deal with the use of Teflon mesh belt with the case of slipping published on

During the use of Teflon mesh belt, often encounter slipping, then how to deal with such a problem?

The tension of Teflon mesh belt on both sides is too small, the slipping caused by the tension of the mesh belt from the drum is not enough, this situation generally occurs in the start, the solution is to adjust the tension device, increase the friction of mesh belt and the drive shaft.

Passive bearing damage does not turn or up and down the roller bearing damage does not turn, causing damage to the end of the floating too much, there is no timely repair and replacement has been damaged or rotating parts are not flexible, so that increased resistance caused by slipping.

Point power start too fast can also form a slip, at this time can be slow start, can also use Tyrone reducer, but also can effectively overcome the slip phenomenon.

Teflon mesh with too large load will also cause slipping. At this point the favorable side of the slip is the motor played a protective role. Otherwise a long time reducer or motor will be burned.

The friction between the drive shaft and the mesh belt is not enough to cause slipping, and the reason is that there is water or environmental humidity. The solution is in the roller coated with PVC adhesive tape.

Teflon mesh belt with regular maintenance and repair, so that can enlarge the use value of mesh belt, reduce the cost of investment and increase the production efficiency of enterprise products.

Regularly check whether the mesh belt surface is flat, with or without garbage or oil.
Regularly check whether the mesh belt with the driving wheel and passive wheel is loose, and timely adjustment.
Regularly check the mesh belt with or without elongation elongation phenomenon.
Regularly check the mesh belt dryer driving wheel and driven wheel is rotating properly, you can add regular lubricants.
Periodically check the mesh belt edge and joints, to avoid damage due to the mesh belt deviation caused by deviation and packet edge off.

Teflon conveyor belt wear and tear how to repair

Teflon conveyor belt wear and tear how to repair published on

Teflon conveyor belt although has the properties of wear-resistant high temperature, but because of the load capacity and running fast, after a long run back and forth, the wear resistance of the conveyor belt will decline, Inevitably there will be wear and tear, glass fiber leakage problems encountered in these problems should be promptly repaired, otherwise the conveyor belt will be scrapped, affecting production schedule. So how to fix it?

Teflon conveyor belt sent wear common repair methods: Rubber patch up method, local rubber vulcanization method and rubber repair rubber covered repair method.

Adhesive patch method has the advantage of fast repair, as long as the subsidy at the polished cleaning adhesive after the cast glue, and then paste the patch even if the patch is good, you can boot run. The patch method is not very reliable, because after 60 ~ 90d operation, the film will fall off, And the use of the patch method, the conveyor belt can not run in a wet environment. Because the water vapor will accumulate in the gap between the bonding surface, rust wire rope, a long time will rust off the rope, or even the entire conveyor belt fracture, and the repair cost is relatively high.

Local vulcanized rubber vulcanization method is to use a small pair of local breakage vulcanized, sulfide by the size limit, repair speed is relatively slow, only 5m / h. So the repair method is not suitable for long-distance repair.

Rubber repair rubber cover method is to two-component polyurethane glue mixed together even after mixing, and then to fill the surface to be repaired, such as 5 to 6 hours after curing, curing will form an elastomer. The time required for general cure depends on the ambient temperature. After curing the appearance of the colloid and the conveyor belt has a good adhesive properties, bonding and sealing performance is very good, does not appear in the film after running off the problem, it will not operate in a wet environment rust off the rope, causing the belt breakage problems. After the repair method adopted, the abrasion resistance is very excellent, and the problem of local wear of the conveyor belt is effectively solved. At present, the repair method is the best effect, effectively extending the service life of the conveyor belt and avoiding the occurrence of broken belt.
