Rubber Conveyor Belt Deviation Problem

- Aug 14, 2018-

First, adjust the load roller set

When the belt of the belt conveyor is deflected in the middle of the belt conveyor, the position of the roller group can be adjusted to adjust the deviation; during the manufacturing, the mounting holes on both sides of the roller group are processed to grow holes for adjustment. The specific method is which side the belt is biased, which side of the roller set moves forward toward the belt advancement direction, or the other side moves backward. When the belt is deflected in the upward direction, the lower position of the roller set should move to the left, and the upper position of the idler set moves to the right.

Second, install the centering roller set

There are many types of self-aligning roller sets, such as intermediate shaft type, four-bar type type, vertical roller type, etc. The principle is to use the blocking or idler to rotate in the horizontal direction to block or generate lateral thrust to make the belt automatically reach the adjustment belt. The purpose of deviation. This method is generally reasonable when the total length of the belt conveyor is short or when the belt conveyor is operated in both directions, because the shorter belt conveyor is more prone to deviation and is not easy to adjust. Long belt conveyors are best not to use this method because the use of the centering roller set has a certain impact on the life of the belt.

Third, adjust the drive roller and redirection roller position

The adjustment of the driving roller and the redirecting roller is an important part of the belt deviation adjustment. Since a belt conveyor has at least 2 to 5 rollers, all drums must be installed at a position perpendicular to the centerline of the belt conveyor. If the deflection is too large, deviation will occur. The adjustment method is similar to the adjustment of the roller set. For the head roller, such as the belt, to the right side of the drum, the bearing housing on the right side should move forward, and the belt should be moved to the left side of the drum. The bearing housing on the left side should move forward, and the corresponding bearing can also Move the left bearing housing back or the right bearing housing back. The tail roller is adjusted in the opposite way to the head roller. After repeated adjustments until the belt is adjusted to a better position. It is best to install the position accurately before adjusting the drive or reversing the drum.
