The normal operation of the belt conveyor manufactured by a ratchet strap manufacturer must enable the conveyor belt to have a certain tension. The equipment that provides the tension is the tensioning device. The so-called "tightening" has the meaning of absorbing the elongation of the conveyor belt and providing tension to the conveyor belt. The functions of the general conveyor tensioning device are as follows:

 

(1) Make the conveyor with sufficient tension to ensure that sufficient driving force can be generated between the conveyor belt and the drive roller to prevent slipping;
(2) Ensure that the tension at each point of the conveyor belt is not lower than a given value to prevent excessive slack of the conveyor belt between the rollers, which may cause material scattering and increase running resistance;
(3) Compensate the elastic and plastic deformation of the conveyor belt;
(4) Provide the necessary stroke for the conveyor belt to reconnect.

 

For long-distance, high-tension conveyors, it is necessary to consider providing different tensioning forces in different working conditions to improve the service life of the conveyor belt. When the conveyor starts and brakes, the tension required to ensure the transmission of the starting and braking force is different, and the tension distribution of the conveyor belt is also different. It is necessary to consider meeting the sag condition of the conveyor belt under these two working conditions. The required tensioning force is correspondingly increased, so it is required to have a greater tensioning force during starting and braking than during normal operation. This requires that the tensioning device can provide corresponding tensioning force under different working conditions.

 

In practical applications, a water tank has been used as a tensioning device, and the water tank is filled with water before the start of the conveyor to increase the tension. When the conveyor reaches the normal operating state, the water is released, and the tension is reduced to meet the tension of normal operation.
