One of the most common faults is conveyor belt runout when the belt conveyor is in operation. There are many reasons for deviation, the main reason is the low installation accuracy and poor daily maintenance. During the installation process, the head and tail rollers and the middle idler are as far as possible on the same center line and parallel to each other to ensure that the conveyor belt is not biased or biased. In addition, the strap connector must be correct and both sides should have the same circumference.
In the course of use, if there is a deviation, the following checks should be made to determine the cause and make adjustments. The parts and methods of frequent inspection of conveyor belts are:
(1) Check the misalignment of the idler transverse centerline with the longitudinal centerline of the belt conveyor. If the non-coincidence value exceeds 3mm, it should be adjusted using the long mounting holes on both sides of the roller group. The specific method is to which side the conveyor belt is biased, which side of the idler group is advanced in the direction of advancement of the conveyor belt, or the other side is moved backward.
(2) Check the deviation of the two planes of the head and tail frame mounting bearing seats. If the deviation between the two planes is greater than 1 mm, adjust the two planes in the same plane. The adjustment method of the head drum is: if the conveyor belt is offset to the right side of the drum, the bearing seat on the right side of the drum should move forward or the left bearing seat should move backward; if the conveyor belt runs to the left side of the drum, then The bearing housing on the left side of the drum should move forward or move the right bearing housing back. The adjustment of the tail drum is just the opposite of the head drum.
(3) Check the position of the material on the conveyor belt. The material is not centered on the cross section of the conveyor belt, which will cause the conveyor belt to run off.
If the material is skewed to the right, the belt is deflected to the left and vice versa. When used, the material should be centered as much as possible. In order to reduce or avoid such deviations from the conveyor belt can increase the baffle, change the direction and position of the material.
