How to solve the belt deviation of the automatic folder gluer

In the use of folder-gluer in the printing and packaging industry, the belt is an indispensable accessory, and the phenomenon of belt deviation is inevitable during use. So how to solve the problem of folder-gluer belt mistracking? Next, Yonghang puts forward the following insights on this issue, I hope it can help you!

There are many reasons for the belt deviation of the folder-gluer, the main reason is the low installation accuracy and poor daily maintenance

1. Check the deviation value of the two planes of the bearing seat installed on the head and tail frame. If the deviation of the two planes is greater than 1mm, the two planes should be adjusted in the same plane. The adjustment method of the head roller is:

If it deviates to the right side of the drum, the housing on the right side of the drum should be moved forward or the left side of the housing should be moved backward. If it deviates to the left side of the drum, the housing on the left side of the drum should be moved forward or the right housing should be moved backward. The tail drum is adjusted in the opposite way to the head roller.

2. Check the position of the product on the belt of the folder-gluer. The product is not centered in the cross-section, which will lead to mistracking. If the product is biased to the right, the belt is deviated to the left, and vice versa.

When using, the product should be centered as much as possible. In order to reduce or avoid such mistracking, a baffle can be added to change the orientation and position of the product.

3. Check the non-coincidence between the transverse centerline of the idler and the longitudinal centerline of the conveyor mesh. If the coincidence value does not exceed 3mm, it should be adjusted by using the long mounting holes on both sides of the idler set. The specific method is which side to deviate towards, which side of the idler set moves forward in the forward direction, or the other side moves backward.

It depends on the specific situation, there is a problem with the equipment, and there is also a problem with the belt! I suggest you refer to some technical books in this area, such as a technical book on back-end solutions published by Shanghai Meiyin Media.

1. Check whether the load of the folder-gluer belt exceeds the standard. If the load is too large and exceeds the capacity of the motor, it will be easy to slip, although the slippage at this time can play a role in protecting the motor, but it is necessary to adjust the feeding amount in time to control it within the maximum load to avoid the appearance of material slippage.

2. If the starting speed is too fast, it is easy to cause the belt of the folder-gluer to slip. In view of this situation, the starting speed can be adjusted appropriately and the slow start can be used instead, which can effectively cause the customer to slip.

3. It is necessary to eliminate slippage caused by insufficient friction between the transmission roller and the conveyor belt. Usually this is caused by water on the conveyor belt or a humid environment, and a blower can be used to blow the rosin powder on the drum.

4. Check the tension of the folder-gluer belt.

The deviation of the paper conveyor belt of the box gluing machine is a common fault in the operation of the box gluing machine, which is generally due to the poor pit paper; The belt sucks too much; The pressure is too low; pressure rolling slip; The belt pressure roll and the suction air tail are not equal to the other causes! The impact of belt deviation is very large, from the actual situation, the impact of the tapering belt deviation of the sticking box machine on the operation and production of machinery mainly includes the following aspects:

1.It can lead to system failure and stop operation and affect production efficiency: When the belt deviation reaches a certain level, the belt will trigger an emergency stop device for anti-deviation, causing the operating system to stop and affect the production process.

2.It will cause abnormal damage to the main components of the machinery: when the belt deviates, it will increase the axial force on the roller and roller, causing damage to the drum shaft and bearing; It will cause the material to spill and return to the belt, causing abnormal wear of the belt and the roller, and shortening the service life; Abnormal wear and tear can occur with the bracket, resulting in wear on the edge of the belt and shortening the service life.

3.It will form a potential safety hazard: due to the serious deviation of the belt, it will cause the belt to flip, resulting in the unilateral force of the belt exceeding the longitudinal pulling force of the belt, which will cause potential safety hazards such as lateral tearing of the belt.

4.pollute the environment, affect the quality of conveyed materials, and often cause coal dust in the process of spilling and cleaning, causing pollution to the environment; At the same time, the spilling of materials also affects the quality of the conveyed goods.

It is recommended that you regularly check the operation of the paper conveyor belt of the gluing machine, and deal with it in time when you find the phenomenon of deviation to avoid greater losses!

The folder-gluer belt box can't go through, and this situation is also commonplace on the folder-gluer belt. This is mainly due to the following two points:

The first point is that the center line of the device is not parallel, which will make the belts on both sides inconsistent.

The second point is that the quality of the belt of the folder-gluer is unqualified, which is determined by the mold, such as uneven elongation and unstraight bending, which makes the belt deviate during the operation of the equipment, so that it cannot go over!

Yonghang provides a few points 1, the starting speed is too fast can also form skidding. At this point, it can be started slowly. If the squirrel cage motor is used, it can be jogged twice before starting, which can also effectively overcome the slippage phenomenon.

2. The initial tension is too small. The tension leaving the drum is not enough to cause slippage. This situation generally occurs at start-up, and the solution is to adjust the tensioning device and increase the initial tension.

3. The load is too large, and it will slip if it exceeds the capacity of the motor. The positive side of skidding at this point is that it protects the motor. Otherwise, after a long time, the motor will be burned. But for operation, it is a skidding accident.

4. The friction between the transmission drum and the belt is not enough to cause slippage. Most of the reasons why it should not be carried are water or the environment is humid. The solution is to add some minced rosin to the drum. However, be careful not to add it by hand, but blow it in with a blower device to avoid accidents.

5. The tail roller bearing is damaged and does not rotate or the upper and lower roller bearings are damaged and do not rotate too much. The reason for the damage is that the tail floats and sinks too much, and the parts that have been damaged or rotated inflexibly are not repaired and replaced in time, which increases the resistance and causes slippage.
