Conveyor belt

Conveyor belt deviation is a common phenomenon observed during equipment use, which can easily cause abnormal production during the production process. Below are some common reasons and solutions for belt deviation.

Adjustment of tension: The adjustment of the tension of the conveyor belt is a very important step in adjusting the deviation of the conveyor belt. The two deflection rollers at the upper part of the heavy hammer tensioning point should be perpendicular to the length direction of the conveyor belt and also perpendicular to the gravity vertical line, ensuring that their axis centerline is horizontal.
When using spiral tensioning or hydraulic cylinder tensioning, the two bearing seats of the tensioning drum should translate simultaneously to ensure that the drum axis is perpendicular to the longitudinal direction of the conveyor belt. The specific adjustment method for conveyor belt deviation is similar to the adjustment at the drum.

Adjust the bearing roller group: When the conveyor belt of the conveyor belt deviates in the middle of the entire conveyor belt, the position of the roller group can be adjusted to adjust the deviation; During manufacturing, the mounting holes on both sides of the roller group are machined into long holes for adjustment.
The specific method is to determine which side the conveyor belt is biased towards, which side of the roller group moves forward towards the direction of the conveyor belt, or which side moves backward towards the other side.
If the conveyor belt deviates in the upward direction, the lower part of the roller group should move to the left, and the upper part of the roller group should move to the right.

Installation of self-aligning roller set: There are various types of self-aligning roller sets, such as intermediate shaft type, four-bar linkage type, vertical roller type, etc. The principle is to use blocking or roller rotation in the horizontal plane to block or generate lateral thrust, so that the conveyor belt automatically centripetal to achieve the purpose of adjusting the conveyor belt deviation.
It is generally reasonable to use this method when the total length of the conveyor belt conveyor is short or when the conveyor belt conveyor is running in both directions, because shorter conveyor belt conveyors are more prone to deviation and difficult to adjust. It is best not to use this method for long conveyor belt conveyors, as the use of self-aligning roller sets will have a certain impact on the service life of the conveyor belt.
