Analysis of conveyor belt deviation adjustment

  Mountain dressing equipment: analysis of conveyor belt deviation adjustment

  Belt conveyor is widely used in sand production lines and mineral processing equipment, while in some building materials equipment is also a common machine, it is widely used, high efficiency. Belt conveyor running belt deviation is the most common fault. In order to solve this type of fault focus should pay attention to the installation of the dimensional accuracy and daily maintenance. There are a variety of reasons for deviation, according to different reasons to deal with differences.

  Adjust the load carrier group: the belt of the belt conveyor in the middle of the belt conveyor can be adjusted when the position of the roller group to adjust the deviation; in the manufacture of the roller group on both sides of the installation hole are processed into long holes in order to adjust The The specific method is the side of the belt which side, the side of the roller group toward the belt forward direction forward, or the other side after the move. The belt is moved in the upward direction and the lower part of the roller group should move to the left and the upper position of the roller group is moved to the right.

  Installation of aligning roller set: There are many types of aligning roller set, such as intermediate rotary shaft, four-link type, vertical roller, etc., the principle is to use the block or roller in the horizontal direction of the rotation to stop or produce horizontal thrust Belt automatically to the heart to adjust the belt deviation of the purpose. It is generally reasonable to use this method when the total length of the belt conveyor is shorter or when the belt conveyor is bi-directionally operating because the shorter belt conveyor is more prone to deviation and is not easy to adjust. The long belt conveyor is best not to use this method, because the use of aligning roller group will have a certain impact on the life of the belt.

  Adjust the drive roller and reorient roller position: drive roller and adjust the drum adjustment is an important part of the belt deviation adjustment. Because a belt conveyor has at least two to five drums, all the drums must be mounted at a position perpendicular to the centerline of the belt conveyor. If the skew is too large, the deviation will occur. The adjustment method is similar to adjusting the roller group. For the head roller, such as the belt to the right side of the drum deviation, the right side of the bearing seat should move forward, the belt to the left side of the roller deviation, the left side of the bearing should move forward, the corresponding can also Move the left side bearing seat back or the right side bearing seat backwards. The tail roller is adjusted in the opposite direction to the head roller. After repeated adjustments until the belt transferred to the ideal location. It is advisable to install the position correctly before adjusting or reversing the drum.

  Tension adjustment: belt tension adjustment is a belt conveyor deviation adjustment of a very important part. The two rewinding rollers in the upper part of the hammer tension should be perpendicular to the gravitational perpendicular to the longitudinal direction of the belt, ie to ensure that the centerline of the shaft is horizontal. When tension is applied with a screw tension or a hydraulic cylinder, the two bearing housings of the tension roller should be translated at the same time to ensure that the roller axis is perpendicular to the longitudinal direction of the belt. The adjustment of the specific belt deviation is similar to that of the roller.
