[0002] The conveyor belt roller is a component used to tighten the conveyor belt and assist the conveyor belt in transmission. The main body includes a main shaft, a shell, a bearing and a cover.

[0003] Commonly used conveyor belt rollers generally have an outer shell mounted on the main shaft, and bearings installed at both ends of the main shaft, located between the outer shell and the main shaft, and clamped between the main shaft and the outer shell through a cover, and the two ends of the outer shell are pressed inward by pressing, thereby fixing the cover and the bearing.

[0004] The conveyor belt rollers produced by this pressing method are simple in process and stable in structure. However, since the two ends of the shell are pressed inward, the shell is not easy to disassemble, and the pressure bearing capacity of the end bearing part is poor, and the maintenance cycle is short. Even if the shell is damaged, it needs to be replaced as a whole. In addition, if rollers of different sizes need to be replaced, the rollers need to be replaced as a whole, which has high maintenance and replacement costs. In use, rollers installed by pressing the end covers have poor smoothness. Utility Model Content

[0005] The purpose of the utility model of the present application is to improve the problems of high maintenance and replacement costs and poor smoothness of conveyor belt rollers assembled by pressing, and the present application provides a conveyor belt roller structure.

[0006] The conveyor belt roller structure provided in this application adopts the following technical solution:

[0010] The middle ring sleeve is sleeved on the bearing, and one end close to the center of the main shaft is fixed with an inner ring plate that abuts against the end surface of the bearing;

[0011] The outer cylinder has circumferential inner walls at both ends abutting against the circumferential outer wall of the middle ring sleeve;

[0012] The outer ring plate is fixed to one end of the middle ring sleeve close to the main shaft end and abuts against the end of the outer cylinder;

[0013] The inner clamping plate is inserted into the inner wall of the middle ring sleeve, pressed tightly against the inner wall of the middle ring sleeve and the inner ring plate of the bearing box, and the inner clamping plate is made of elastic metal material.

[0014] Optionally, an inner ring groove is provided on the circumferential inner wall of the middle ring sleeve, and the inner clamping plate is tightly pressed against the inner ring groove.

[0015] Optionally, the inner clamping plate is a "C"-shaped structure, and the circumferential inner wall will not abut against the main shaft.

[0016] Optionally, the inner walls at both ends of the inner clamping plate are fixedly provided with raised plates, and the raised plates are provided with traction holes.

[0017] Optionally, a positioning plate is fixedly provided on the main shaft, and the positioning plate abuts against one end of the main shaft that faces the center of the main shaft in the circumferential direction.

[0018] Optionally, the main shaft is provided with an outer ring groove at a position directly opposite to the inner ring groove, and an outer clamping plate is clamped in the outer ring groove, and the outer clamping plate is made of elastic metal material.

[0019] Optionally, the outer clamping plate is in a "C" shape, the portion opposite to the opening does not abut against the outer ring groove, and the circumferential outer walls at both ends are fixed with outer convex plates, and the outer convex plates are provided with unlocking holes.

The fastening sleeve 2 is installed on the circumferential outer wall of the bearing 3, and the outer cylinder 5 is installed on the fastening sleeve 2. The fastening sleeve 2 fixes the positions of the bearing 3 and the outer cylinder 5 to each other. An installation component 4 is provided between the fastening sleeve 2 and the main shaft 1 to fix the positions of the fastening sleeve 2 and the main shaft 1 to each other.

[0030] refer to Figure 2 The clamping sleeve 2 includes a middle ring sleeve 21, an inner ring plate 22 and an outer ring plate 23. The middle ring sleeve 21 is sleeved on the bearing 3, and the circumferential outer wall abuts against the inner wall of the outer cylinder 5. The inner ring plate 22 is fixed to one end of the middle ring sleeve 21 close to the center of the main shaft 1, and the inner ring plate 22 abuts against one end of the bearing 3 close to the positioning plate 11. The outer ring plate 23 is fixed to one end of the middle ring sleeve 21 away from the inner ring plate 22, and is used to abut against the end of the outer cylinder 5. The middle ring sleeve 21, the inner ring plate 22 and the outer ring plate 23 are integrally formed.

[0031] During installation, a fastening sleeve 2 is first put on the main shaft 1, and then one of the bearings 3 is installed. After the fastening sleeve 2 is moved to the bearing 3, the outer cylinder 5 is put on the fastening sleeve 2. Then another fastening sleeve 2 is put on the other end of the outer cylinder 5, and finally the other bearing 3 is installed on the main shaft 1, and fixed by the installation component 4 to realize the assembly of the roller.

[0032] refer to Figure 2, the mounting assembly 4 includes an inner card plate 41 and an outer card plate 42. The inner card plate 41 and the outer card plate 42 are made of the same material, both of which are elastic metal materials, and in this embodiment, they are spring steel. An inner ring groove 211 is provided on the circumferential inner wall of the middle ring sleeve 21, and the inner card plate 41 is "C"-shaped. When the inner card plate 41 is in a natural state, it is tightly pressed against the inner wall of the inner ring groove 211. The portion of the inner card plate 41 extending out of the inner ring groove 211 abuts against the end of the bearing 3. The circumferential inner wall of the inner card plate 41 will not abut against the main shaft 1. The inner wall at both ends of the inner card plate 41 is fixed with a raised plate 411, and the raised plate 411 is provided with a traction hole 4111. The main shaft 1 is provided with an outer ring groove 12 at a position directly opposite to the inner ring groove 211, and the outer card plate 42 is partially located in the outer ring groove 12 and is in a natural state, and the outer card plate 42 abuts against the end of the bearing 3.
