Description

Technical Field

[0001] The present application relates to the technical field of conveying rollers, and in particular to a modular conveying roller. Background Art

[0002] The conveyor rollers currently in use are made of a whole piece of roller skin welded on the roller hub, and the surface of the roller skin is covered with roller rubber. After the roller skin is covered with rubber, the rubber sheet on it will naturally wear out or be squeezed and damaged by external force during the daily operation of the roller, so the roller needs to be repaired by rubber covering again.

[0003] At present, there are usually two methods for repairing the conveyor rollers with rubber coating. One is to dismantle the rollers and replace them, and send the old parts to the manufacturer for hot vulcanization rubber coating. The other is to clean the residual rubber on the roller and grind the roller skin on site, and then perform on-site gluing and rubber coating.

[0004] Because the drum skin and wheel hub of the current conveyor roller are an integral structure, it is inevitable to use the methods in the above two parts when repairing the roller with rubber coating, and both methods have shortcomings. The shortcomings of the first method are: time-consuming and labor-intensive disassembly, difficulty in assembly, long return to the factory period, and high cost of spare parts inventory; the shortcomings of the second method are poor on-site working environment, difficulty in construction and management, many safety hazards, difficulty in ensuring the quality of gluing, time-consuming and labor-intensive rubber coating, high cost, high failure rate, and frequent accidents; therefore, in order to solve the above problems, the present application provides a modular conveyor roller.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1 - Fig. 9 This application is described in further detail.

[0030] Embodiment 1:

[0031] A modular conveyor roller, referring to Figure 1 - Fig. 9 , including a rotating shaft 1 in the middle position, a hub A2 and two hubs B3 are welded on the outer wall of the rotating shaft 1, the two hubs B3 are located at both ends, and the hub A2 is located in the middle. The outer sides of the hubs A2 and B3 are covered with a fan-shaped plate A4 and a fan-shaped plate B5, which are combined with each other to form a cylindrical structure, and the side edges of the two are fitted to ensure the roundness of the drum.

[0032] The fan-shaped plate A4 and the fan-shaped plate B5 are metal structures, and their arc-shaped plates are metal substrates 71. The outer sides of the metal substrates 71 are bonded to rubber plates 72 through adhesive layers 73. The edge positions of the rubber plates 72 and the fan-shaped plates A4 and B5 are all located on the same radius line to ensure the tightness of the fit between the rubber plates 72.

[0033] Connectors A8 are welded at both ends and the middle of the sector plate A4. A through hole is provided on the connector A8. Bolt holes A31 are provided on the hub A2 and the hub B3. The connector A8 is fastened and installed between the bolts B10 and the bolt holes A31. The connectors A8 at both ends are fixedly connected to the hub B3, and the middle connector A8 is fixedly connected to the hub A2. The installation of each sector plate A4 is completed in sequence along the clockwise direction or counterclockwise direction.

[0034] When installing the sector plate B5, firstly, thread the bolts A9 on the two remaining bolt holes A31 on the wheel hub A2, align the through hole on the connecting piece C51 of the sector plate B5 with the position of the bolt A9, and slide it onto the bolt A9. At this time, the sector plate B5 is covered on the outside of the wheel hub A2, and then the connecting piece B6 is fixedly installed in the bolt holes B52 at both ends of the sector plate B5. The position of the bolt hole C61 of the connecting piece B6 corresponds to the bolt hole A31, and the position of the bolt hole D62 corresponds to the position of the bolt hole B52. After the installation is completed, the sector plate B5 is installed on the outside of the wheel hub, and the overall installation of the drum is now completed.

[0035] During dismantling, you only need to remove the fan plate B5 first, and then you can operate on the fan plate A4 that needs to be removed. The overall size of the drum is set to meet the requirement that in the absence of the fan plate B5, all the connection positions of the fan plate A4 can be operated, thus ensuring that the installation and disassembly of the device can proceed smoothly.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
