Description

BELT ADJUSTING CARRIER ROLLER FOR SMALL ANGLE FINE HUS03060
ADJUSTMENT
FIELD OF TECHNOLOGY
The present invention relates to the technical field of carrier rollers, particularly to a belt adjusting carrier roller for small angle fine adjustment.
BACKGROUND
A carrier roller is an important part of a belt conveyor. There are various types of carrier rollers large in quantity. The carrier roller can support the weights of a conveyor belt and materials, accounts for 35% of the total cost of a belt conveyor and generates more than 70% of resistance. Therefore, the quality of the carrier roller is particularly important. The carrier rollers include steel and plastic carrier rollers.
The carrier roller plays a role of supporting the weights of a conveyor belt and materials. During transporting and transferring materials, the belt conveyor drives parts such as a carrier roller tube body, a bearing pedestal and a compression roller to perform rotating motions by means of a frictional force between the conveyor belt and the carrier roller. The carrier roller, together with the conveyor belt, is used for transferring cargoes under test. Presently, a current carrier roller is fixed, and cannot be adjusted after being designed and installed. Since an edge surface of the carrier roller is smooth and is small in frictional force, a sliding situation easily occurs, which is adverse to operation of the carrier roller.

A slide bar can further be driven simultaneously to ascend and 7505060 descend on the supporting plate so as to adjust a height distance between the compression roller column and the carrier roller body. By observing a scale, the angle accuracy for small angle fine adjustment can be controlled, so that it is guaranteed that a belt is uniformly stressed. By arranging an anti-skid pad on the carrier roller body, the frictional force between the carrier roller body and the belt can be increased finitely to prevent deviation.
