Four-direction belt conveyor self-deviation-adjusting roller with axial displacement

Abstract

The invention discloses a four-direction belt conveyor self-deviation-adjusting roller with axial displacement. The four-direction belt conveyor self-deviation-adjusting roller comprises a roller shaft, a near-shaft inner pipe, a middle inner pipe, a near-tube inner pipe and a roller tube which are arranged in sequence from inside to outside, a shaft pin is arranged on the middle parts of the roller shaft and the near-shaft inner pipe, a front-rear deviation adjusting device and a left-right deviation adjusting device are arranged between the near-shaft inner pipe and the middle inner pipe, pipe end sealed bearing devices are separately installed at both ends of the middle inner pipe and the near-tube inner pipe in a sealing mode, and rubber seal sleeves are separately connected between the two ends of the middle inner pipe or the two pipe end sealed bearing devices and the roller shaft; the shaft pin, the near-shaft inner pipe, the middle inner pipe, the near-tube inner pipe and the front-rear deviation adjustment device are matched to realize the self-adjustment of a conveyor belt after the deviation of the front and back directions, and the middle inner pipe, the near-tube innerpipe and the front-rear deviation adjusting device are matched to realize the self-adjustment of the conveyor belt after the deviation of the left and right directions, so that the phenomenon of damage to the roller and other components caused by the deviation of the conveyor belt is reduced, all self-deviation-adjusting components are arranged in the roller, and the layout and installation of other components of a belt conveyor are not affected.

Description

technical field [0001] The invention relates to the technical field of belt conveyors, in particular to a self-adjusting eccentric roller of a four-way belt conveyor with axial displacement. Background technique [0002] A number of rollers are installed in parallel on the belt conveyor, and the rollers can support the conveyor belt and materials during the operation of the belt conveyor, and at the same time realize the conveying drive of the conveyor belt and materials. During the working process of the idler roller, its roller shaft and the fixed plates at both ends are fixedly installed on the bracket of the belt conveyor, so as the working time prolongs, the surface of the idler roller will appear relative rolling under the action of the friction force of the conveyor belt , causing the conveyor belt to deviate, increasing the running resistance of the conveyor belt, thereby accelerating the wear and damage of the conveyor belt, and the structure of the deviation adjust...

Problems solved by technology

During the working process of the idler roller, its roller shaft and the fixed plates at both ends are fixedly installed on the bracket of the belt conveyor, so as the working time prolongs, the surface of the idler roller will appear relative rolling under the action of the friction force of the conveyor belt , causing the conveyor belt to deviate, increasing the running resistance of the conveyor belt, thereby accelerating the wear and damage of the conveyor belt, and the structure of the deviation adjustment equipment currently used on the belt conveyor is complicated, and the installation takes up a large space, resulting in The effect of deviation adjustment is not ideal, the purpose of automatic deviation adjustment and reset cannot be achieved, and it is difficult to control the centered operation of the conveyor belt

The long-term deviation of the conveyor belt will also cause damage to the idler roller and other components, which will increase the maintenance cost and lengthen the downtime, resulting in an increase in production cost and a decrease in production efficiency.
