Conveyor | Conveyor belt deviation causes and solutions
Belt misalignment is one of the most common faults when the belt is running. There are many reasons for the deviation, the main reasons are low installation accuracy and poor daily maintenance. During the installation process, the head and tail rollers and the middle idler should be on the same center line as much as possible, and they should be parallel to each other to ensure that the conveyor belt is not deviated or less deviated. In addition, the strap joints should be correct and the circumference should be the same on both sides. During use, if deviation occurs, the following inspections should be made to determine the cause and make adjustments. The parts and treatment methods that are often checked for conveyor belt deviation are:
1) Check the misalignment between the lateral centerline of the idler and the longitudinal centerline of the belt conveyor. If the misalignment value exceeds 3mm, it should be adjusted using the long mounting holes on both sides of the idler set. The specific method is which side of the conveyor belt is biased, which side of the idler 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 head and tail frame mounting bearing housing. 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 drum is: if the conveyor belt deviates 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 deviates to the left side of the drum, the The bearing housing on the left side of the drum should move forward or the right bearing housing back. 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. The material is not centered on the cross section of the conveyor belt, which will cause the conveyor belt to deviate. If the material is skewed to the right, the belt is skewed to the left and vice versa. When using, the material should be centered as much as possible. In order to reduce or avoid such conveyor belt deviation, a baffle can be added to change the direction and position of the material.
