Conveyor belt deviation is a common fault of belt conveyors. It often causes material spilling or belt edge wear, which reduces the service life of the belt. In severe cases, it can also cause belt tears, high-speed operation of belt edge materials, damage to other equipment or even injury. Affect safe production and may cause major economic losses. Therefore, effectively preventing and quickly adjusting the belt deviation is one of the important problems that should be paid attention to and solved in the installation and use of the belt conveyor.
Conveyor belt conveyor is the most common fault when the belt is running off. In order to solve this kind of fault, it is important to pay attention to the dimensional accuracy of the installation and the daily maintenance. There are many reasons for deviations, and they need to be dealt with differently according to different principles. Of course, in order to prevent deviation, many customers add guide strips on the back of the belt or in the middle to avoid this problem.
1. Adjust the position of the roller group: the correction method is which side of the belt is biased, and the roller on that side moves forward along the belt running direction, or the other side moves backward. It is characterized by a small degree of belt deviation correction, and frequent dynamic adjustments are required.
2. Adjust the position of the roller: Except for the tail roller, the method of correcting deviation is similar to that of adjusting the position of the roller group. The adjustment method of the tail roller is the opposite. It is characterized by a large degree of correction, but it needs to be stopped for multiple adjustments.
3. The adjustment of the tension, the adjustment of the tension of the flat belt is a very important part of the deviation adjustment of the flat belt conveyor. The two reversing rollers above the tension of the heavy hammer should be perpendicular to the length direction of the flat belt and should be perpendicular to the vertical line of gravity, which is to ensure that their shaft centerline is level. 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 and the longitudinal direction of the belt can be vertical.
