1. Adjusting the belt of the belt conveyor carrying the roller set can adjust the orientation of the roller set to adjust the deviation when the whole belt conveyor is deflected in the middle of the belt conveyor. During the production, the hole on both sides of the roller set is processed to grow the hole; Adjustment. The detailed method is which side of the belt is inclined; which side of the roller set moves forward in the direction of the belt advancement; or the other side moves backward. When the belt is deflected in the upward direction, the lower position of the idler group should be moved to the left; 3. The upper position of the roller set moves to the right.
2. There are many types of equipment centering roller set, such as center shaft type, four-bar type type, vertical roller type, etc. The principle is to use the obstruction or the roller to change direction in the horizontal plane or to cause lateral thrust. The belt is actively centered to reach the intention of adjusting the deviation of the belt. Usually this method is 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 the shorter belt conveyor is easier to run and not simple. Adjustment. The long belt conveyor is the best not to use this method; because the use of the centering roller set will have a certain impact on the life of the belt.
3. Adjusting the driving roller and the reversing roller The adjustment of the driving roller and the reversing roller is an important part of the belt deviation adjustment. Since a belt conveyor has at least 2 to 5 rollers; the orientation of all the rollers must be straight to the belt. The center line of the length direction of the conveyor; if the deflection is too large, the deviation must be reversed. The adjustment method is similar to that of the adjustment roller set. Regarding the head roller such as the belt running away from the right side of the drum; the bearing housing on the right side should Move forward; the belt runs away from the left side of the drum; then the left bearing housing should move forward; correspondingly, the left bearing housing can be moved backward or the right bearing housing can be moved backward. The adjustment method and head of the tail roller The drum is just the opposite. By repeating the adjustment until the belt is adjusted to a more asymmetrical position. The most accurate device is positioned before adjusting the drive or reversing the drum.
4. Adjusting the tension at the tensioning belt The adjustment of the belt tensioning position is a very important part of the belt conveyor's deviation adjustment. The two reversing rollers on the upper part of the heavy hammer tensioning should be straight except for the length of the belt. In the vertical line of gravity; that is, to ensure the horizontal centerline of the shaft. When using screw tension or hydraulic cylinder tensioning; the two bearing seats of the tensioning drum should be translated together; to ensure that the drum axis is straight with the longitudinal direction of the belt. Detailed belt running The adjustment method of the bias is similar to the adjustment at the drum.
5. Influence of the blanking position at the transfer point on the belt deviation. The blanking direction of the material at the transfer point has a great influence on the deviation of the belt; especially when the projection of the two belt conveyors in the horizontal plane is straight. Generally, the relative heights of the upper and lower belt conveyors at the transfer point should be considered. The lower the relative height is; the greater the horizontal speed of the material; the greater the lateral impact on the base belt; the material is also difficult to center. The material on the surface is skewed; the end causes the belt to run off. If the material is biased to the right side, the belt is deflected to the left side; vice versa. The relative height of the two belt conveyors should be increased as much as possible during the drawing process. The method and scale of the upper and lower funnels, guide troughs, etc. of the space-constrained mobile bulk transporting machinery should be carefully considered. Usually, the width of the guide trough should be about two-thirds of the width of the belt. Or prevent the deviation of the belt to increase the material blocking the material; change the direction and orientation of the material.
6. Two-way operation of belt conveyor deviation adjustment The adjustment of the belt conveyor deviation of the two-way operation is much more difficult than the adjustment of the deviation of the one-way belt conveyor; in the detailed adjustment, one direction should be adjusted first; then adjust Another direction. When adjusting, carefully observe the relationship between the direction of belt movement and the trend of deviation; adjust one by one. The points should be placed on the adjustment of the driving roller and the reversing roller; secondly, the adjustment of the roller and the blanking point of the material. Adjustment. It should be noted that the belt should be evenly stressed in the longitudinal direction of the belt when the joint is vulcanized. When the guide chain is selected, the force on both sides can be balanced.
