, the phenomenon of belt deviation often occurs during operation, there are many reasons that need to be dealt with according to different reasons: adjust the bearing roller group: belt conveyor When the belt of the machine deviates in the middle of the entire belt loading conveyor, the position of the roller group can be adjusted to adjust the deviation; during manufacturing, the mounting holes on both sides of the roller group are processed with long holes for adjustment. Detailed adjustment method, the detailed method is which side of the belt is biased, which side of the roller set moves forward in the direction of belt advance, or the other side moves backward. If the belt deviates in the upward direction, the lower position of the roller set should move to the left, and the upper position of the roller set should move to the right. Installation of self-aligning roller set: There are many types of self-aligning roller set, such as intermediate shaft type, four-link type, vertical roller type, etc. The principle is to use blocking or rollers to roll in the horizontal plane to block or generate lateral thrust. The belt is automatically centripetal to achieve the purpose of adjusting the belt deviation. It is generally fair to use this method 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 deviate and is not easy to adjust. The long belt loading conveyor does not use this method, because the use of the self-aligning roller set will have a certain impact on the service life of the belt. Adjust the position of the driving roller and the redirecting roller: 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, the installation position of all the rollers must be perpendicular to the center line of the belt conveyor's length direction. If the deviation is too large, the deviation will occur. The adjustment method is similar to the adjustment of the roller set. For the head drum, if the belt deviates to the right side of the drum, the bearing seat on the right side should move forward, and the bearing seat on the left side should move forward if the belt deviates to the left side of the drum. Move the left side bearing seat back or the right side bearing seat back. The adjustment method of the tail roller is exactly the opposite of that of the head roller. Adjustment method. After repeated adjustments until the belt is adjusted to a more ideal position. Install the correct position before adjusting the drive or changing the direction of the roller. Adjustment of the tension part: The adjustment of the belt tension part is a very important part of the deviation adjustment of the belt loading conveyor. The two reversing rollers at the upper part of the weight tension should be perpendicular to the vertical direction of the belt in addition to the length of the belt, that is, to ensure that the center line of the shaft is horizontal. When using screw tensioning or hydraulic cylinder tensioning, the two bearing seats of the tensioning roller should be translated at the same time to ensure that the axis of the roller is perpendicular to the longitudinal direction of the belt. The detailed adjustment method of belt deviation is similar to that of the drum.
