Belt deviation is the most common problem during the operation of a belt conveyor. To deal with such problems, it is important to pay attention to the accuracy of the device's scale and regular protection and maintenance. There are multiple factors that can cause deviation, and it needs to be addressed based on the differences in each factor.
1. When the belt of the belt conveyor carrying the roller group deviates in the middle of all belt conveyors, the orientation of the roller group can be adjusted to adjust the deviation; During manufacturing, the holes on both sides of the roller group are machined with growth holes for adjustment. The detailed adjustment method is to determine which side the belt tends towards, which side of the roller group moves forward towards the direction of the belt, or which side moves backward. If the belt deviates in the upward direction as shown in Figure 1, 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.
2. Device centering roller group There are various types of centering roller groups, such as central shaft type, four-bar linkage type, vertical roller type, etc. The principle is to use a blocking or roller to rotate in the horizontal plane to block or generate lateral thrust, so that the belt can actively move towards the center and achieve the intention of adjusting the belt deviation. Usually, this method is more reasonable when the total length of the belt conveyor is short or when the belt conveyor is running in both directions. The reason is that shorter belt conveyors are easier to deviate and not easy to adjust. It is best not to use this method for long belt conveyors, as the use of self-aligning roller sets will have a certain impact on the service life of the belt.
3. Adjusting the orientation of the driving drum and the reversing drum is an important step in adjusting belt deviation. Due to the fact that a belt conveyor has at least 2 to 5 rollers, the orientation of all rollers must be perpendicular to the centerline of the length direction of the belt conveyor. If the deviation is too large, it will inevitably cause deviation. The adjustment method is similar to adjusting the roller group. For the head drum, if the belt deviates to the right of the drum, the right bearing seat should move forward. If the belt deviates to the left of the drum, the left bearing seat should move forward. Correspondingly, the left bearing seat can also be moved backward or the right bearing seat can be moved backward. The adjustment method of the tail drum is exactly opposite to that of the head drum. Adjustment method. Adjust the belt repeatedly until it reaches the desired position. The best precise device for adjusting the orientation of the drive or redirecting the drum
