Description

A belt conveyor anti-deviation roller

Technical field

The utility model relates to the technical field of cigarette processing equipment, in particular to an anti-deviation roller for a belt conveyor.

Background technique

Belt conveyors are commonly used in the cigarette industry to transport tobacco materials. The middle section of the conveyor belt of the belt conveyor is supported by idlers. After long-term use, due to the dirt on the idlers and the one-way force, the conveyor belt of the belt conveyor is easy to deviate and difficult to correct. In serious cases, it will tear the conveyor. bring.

Utility model content

The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an anti-deviation roller for a belt conveyor to ensure that the conveyor belt of the belt conveyor does not deviate and greatly improve the service life of the conveyor belt.

The utility model is realized through the following technical solutions:

An anti-deviation roller for a belt conveyor, including a central shaft and a hollow roller set on the central shaft. The outer surface of the hollow roller is provided with two sections of spiral protrusions, and the two sections of spiral protrusions rotate in opposite directions. , two sections of spiral protrusions are arranged symmetrically along the axial direction of the hollow roller, and the hollow roller is detachably mounted on the central axis.

As a preferred solution for the above-mentioned anti-deviation roller, the hollow roller is provided with two threaded holes, and the two top screws are screwed into the two threaded holes of the hollow roller and embedded into the two positioning holes of the central shaft. , realize the locking installation of the hollow roller and the central shaft.

As a preferred solution for the above-mentioned anti-deviation roller, the hollow roller is a nylon roller, and the central shaft is a stainless steel shaft.

Compared with the existing technology, the utility model has the following advantages:

The utility model provides an anti-deviation roller for a belt conveyor. By arranging two sections of spiral protrusions in opposite directions on the hollow roller, the conveyor belt supported by the hollow roller is guided by a guiding force directed toward the center of the conveyor belt. , to ensure that the conveyor belt does not deviate or slip, so that the conveyor belt is always transported in the center, which greatly improves the service life of the conveyor belt. In addition, the hollow roller is locked and installed with the central shaft through two jackscrews, which realizes the circumferential and axial locking of the two, and facilitates the convenient installation and disassembly of the hollow roller on the hollow shaft. Easy replacement of rollers.

Detailed ways

The following is a detailed description of the embodiments of the present utility model. This embodiment is implemented based on the technical solution of the present utility model and provides detailed implementation modes and specific operation processes. However, the protection scope of the present utility model is not limited to the following. the described embodiments.

Referring to Figures 1 to 2, this embodiment discloses a belt conveyor anti-deviation roller, which includes a central shaft 1 and a hollow roller 2 set on the central shaft 1. The hollow roller 2 is a nylon roller, and the center Shaft 1 is a stainless steel shaft. The outer surface of the hollow roller 2 is provided with two sections of spiral protrusions. The two sections of spiral protrusions are the first spiral protrusion 3 and the second spiral protrusion 4. The two sections of spiral protrusions have opposite directions of rotation. The hollow roller 2 is arranged symmetrically along the axial direction, and the hollow roller 2 is detachably mounted on the central shaft 1 .

There are two threaded holes 5 on the hollow roller 2. The two top screws 6 are screwed into the two threaded holes 5 of the hollow roller 2 and embedded into the two positioning holes 7 of the central shaft 1 to realize the hollow roller. 2. Locking installation with central axis 1. This installation method not only realizes the circumferential locking of the hollow roller 2 relative to the central axis 1, but also realizes the axial locking of the hollow roller 2 relative to the central axis 1, ensuring that the hollow roller 2 is on the central axis 1 The installation is stable; at the same time, only the top screw 6 is tightened or loosened, and the disassembly and assembly process is convenient and quick.

When in use, the shaft heads at both ends of the central shaft 1 are mounted on the frame of the belt conveyor through bearing rotation, so that the roller is located below the conveyor belt of the belt conveyor and plays a supporting role in the conveyor belt. The design of two sections of spiral protrusions in opposite directions on the hollow roller 2 causes the conveyor belt to receive a guiding force directed toward the center of the conveyor belt, thereby ensuring that the conveyor belt does not slip or deviate, and that the conveyor belt is centered and transported stably, which greatly improves the efficiency of the conveyor belt. Conveyor belt service life.

The above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall be included in the present utility model. within the scope of protection.
