What to do if the conveyor belt/conveyor belt runs off?

Conveyor belt deviation is one of the most common faults during conveyor belt transportation. There are many reasons for deviation. The main reason is low installation accuracy and poor daily maintenance. During the installation process, the head and tail rollers and the intermediate rollers should be on the same centerline as much as possible and parallel to each other to ensure that the conveyor belt is not deviated or less deviated. In addition, the belt joints should be correct and the circumferences of both sides should be the same.

In the course of use, if there is deviation, the following inspections should be performed to determine the cause and make adjustments. The parts and treatment methods that are often checked for deviation of the conveyor belt are:

(1) Check the misalignment between the horizontal centerline of the roller and the longitudinal centerline of the belt conveyor. If the non-coincidence value exceeds 3mm, the long mounting holes on both sides of the roller set should be used to adjust it. The specific method is which side of the conveyor belt is biased, which side of the roller group moves forward in the direction of the conveyor belt, or the other side moves backward.

(2) Check the deviation value of the two planes of the bearing seat of 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 the conveyor belt deviates to the right side of the roller, the bearing seat on the right side of the roller should move forward or the left bearing seat should move backward; if the conveyor belt deviates to the left side of the roller, then The bearing seat on the left side of the drum should move forward or the bearing seat on the right side should move backward. The adjustment method of the tail roller is just the opposite of that of the head roller.

(3) Check the position of the material on the conveyor belt. If the material is not centered on the cross section of the conveyor belt, it will cause the conveyor line to deviate. If the material deviates to the right, the belt deviates to the left, and vice versa. When in use, the material should be centered as much as possible. In order to reduce or avoid the deviation of this kind of conveyor belt, a baffle plate can be added to change the direction and position of the material.
