Novel automatic deviation adjusting roller set

Abstract

A novel automatic deviation adjusting roller set relates to the field of conveyor belt transmission and comprises a roller rack, as well as a roller set and deviation adjusting power structures, which are arranged on the roller rack, wherein the roller set comprises a center roller and a pair of edge rollers which are arranged on two sides of the center roller in bilateral symmetry; each edge roller comprises a main shaft, an adjusting disc, a fixed disc, an adjusting screw, an adjusting nut, an adjustable supporting roller face and a fixed supporting roller face; each edge roller is connected with a main shaft of the center roller through a coupler; the center roller comprises two center rolls in bilateral symmetry; the structures of the center rolls are the same as those of the edge rollers; the deviation adjusting power structures are arranged at the end parts of the edge rollers; each deviation adjusting power structure comprises a deviation adjusting wheel and a bevel gear box; and each deviation adjusting wheel performs torque transfer with the main shafts of the edge rollers through the bevel gear boxes. According to the novel automatic deviation adjusting roller set, deviation adjustment can be performed at any position of a conveyor belt, automatic adjustment is realized, manual intervention is not needed, the problem of deviation of the conveyor belt can be quickly and conveniently solved, the cost is low, the angle adjustment range is wide and full automatic is realized.

Problems solved by technology

[0002] When the belt conveyor is running, the conveyor belt may be caused by insufficient tension, eccentric accumulation of materials, deformation of the frame, defective roller bearings, misalignment of parts in the belt conveyor, skewed conveyor belt joints, and uneven distribution of conveyor belt tension. , material viscosity and other reasons cause the conveyor belt to run unstable and cause deviation

After the belt deviates, it must be adjusted in time through various correction methods to ensure normal production, otherwise it will easily cause accidents such as spilling and spilling materials, and the belt edge after deviation is easy to wear and tear, which will affect the service life

[0003] The existing method is to install a deviation adjustment device at intervals on the conveyor belt to adjust the deviation when the conveyor belt deviates. However, no matter how the deviation adjustment device is set, there are the following disadvantages. Various reasons appear at any position of the conveyor belt, and the existing structure can only be adjusted through the deviation adjustment device at the nearest position, so when the distance between the deviation position and the nearest deviation adjustment device is far, the deviation adjustment device The effect will not be obvious, and the operation of deviation adjustment may cause uneven force in other positions, resulting in new deviation

Some manufacturers improve the effect of deviation adjustment by setting more deviation adjustment devices to reduce the spacing distance, which greatly increases the cost of the entire conveyor belt

Moreover, the adjustment range of the existing deviation adjustment device is limited, and the degree of automation is low
