Tightening device, belt conveyor is a mechanical device driven by friction to transport materials in a continuous manner. To ensure the normal and stable operation of the conveyor, it is necessary to meet the frictional driving force between the driving drum and the conveyor belt, which requires the conveyor belt to have a certain amount of tension. The key to designing a belt conveyor is how to choose a suitable tensioning device.

The function of the tensioning device:

1. Make the conveyor belt have sufficient initial tension, ensure the necessary friction between the conveyor belt and the driving drum, and reserve a certain amount of friction to meet the friction transmission requirements of the driving drum;

2. Ensure the tension at the tension point of the conveyor belt to meet the sag limit conditions of the conveyor belt and ensure the normal and smooth operation of the conveyor;

3. The tightening stroke that meets the elastic elongation requirements caused by the tension driven by the conveyor;

4. Compensate for the long-term elongation of the conveyor belt;

5. Provide necessary travel for conveyor belt joints
