What are the types of SKE belt conveyor tensioning device?

Without a tension take-up device, there would be no pressure on the drive pulley and the conveyor belt would stop or slip. How many different belt conveyor tension devices are normally used in belt conveyor, SKE machinery engineer will show you more:

(1) Heavy weight tensioner 

The tail reversing pulley is fixed on the trolley, and the vertically suspended weight is connected to the trolley. Since the weight of the weight can be a certain value, the belt tension and tension force are constant. Compensation for the extension of the belt, but it requires a large space, a large part, and often cannot be used due to space restrictions. It is easy to use on a fixed long-distance conveyor.

(2) Spiral tensioning device

The bearing seat of the tension pulley is installed on the movable frame. The movable frame can slide on the guide rail, and the screw rod is rotated to advance and retreat the nut on the movable frame and the movable frame together to achieve the purpose of tension and relaxation. Its structure is simple, but the stroke is too small, only suitable for short-distance conveyors, and when the belt stretches on its own, it cannot be automatically tensioned.

(3) Steel rope winch tensioner

This tensioning device uses a small winch for tensioning. The winch generally uses a worm gear reducer to drive th epulley to wind the steel rope to tension the belt. The advantage of this tensioning device is its small size and high tension, so it is widely used in underground belt conveyors, but it cannot be tensioned by itself.
