Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a supporting roller for belt conveyors. Background Art

[0002] Belt conveyors have the advantages of large conveying capacity, simple structure, and standardized components, and are widely used for conveying various materials. Belt conveyors are required for conveying refined cotton during the opening, feeding, alkali soaking, and cooking processes. Existing belt conveyors are primarily composed of support rollers, belts, and drive motors. The drive motor drives the belts wound around rows of support rollers, thereby conveying the materials. The support rollers are important, vulnerable parts in belt conveyors. Because the support rollers are mounted in bearing seats using rotating shafts at both ends via bearings, if the bearings are damaged, the support rollers cannot rotate freely. This causes rolling friction between the belt and the support rollers to shift to sliding friction, increasing the load on the drive motor and rapidly wearing the contact surface between the belt and the support rollers, reducing the belt's service life. To address this issue, we propose a support roller for belt conveyors. Utility Model Content

[0003] The purpose of this utility model is to provide a support roller for belt conveyor in order to solve the above-mentioned shortcomings. When the bearing is damaged, the roller can still rotate normally, which not only avoids the increase of the driving motor load, but also helps to protect the belt and extend the service life of the belt.

[0004] The technical solutions adopted by the present invention to solve the above technical problems are as follows:

[0005] A support roller for belt conveyor includes a roller, a first bearing, a wheel axle, a second bearing and a support. Circular grooves are respectively opened at the centers of both ends of the roller, and through holes penetrating the two ends of the roller are opened in the roller. The paired first bearings are respectively installed in the circular grooves at both ends of the roller, the wheel axle is inserted into the through holes and is rotatably connected to the roller through the paired first bearings, the paired second bearings are respectively installed in the paired bearing seats, the rollers are rotatably installed on the paired bearing seats through the second bearings at both ends of the wheel axle, and the paired bearing seats are respectively fixedly installed on the paired supports.

[0006] Preferably, the surface of the roller is a concave arc surface.

[0007] The beneficial effects that can be achieved by the above technical solutions of the present invention are:

[0008] By installing the first bearing and the second bearing on the rotating shaft at both ends of the roller respectively, when one of the bearings is damaged, the roller can still keep rotating under the action of the other bearing, which not only effectively extends the service life of the belt, but also avoids increasing the operating load of the drive motor.
