Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Reference Figures 1-5 A high-speed wear-resistant polyurethane conveyor roller includes a mounting ring 1, a polyurethane rotating ring 2 fixedly mounted on the surface of the mounting ring 1, a positioning component 3 disposed inside the mounting ring 1, a limit component 4 disposed on both sides of the positioning component 3, and a buffer component 5 disposed on the limit component 4.

[0034] The positioning component 3 includes a positioning strip 300 fixedly installed on the inner ring of the mounting ring 1 and a rotating rod 301 inserted into the mounting ring 1. A limiting groove 302 is provided on the rotating rod 301. Screws 303 are inserted on both sides of the upper surface of the positioning strip 300. The bottom of the screws 303 passes through the positioning strip 300 and extends into the interior of the limiting groove 302, where they are threadedly connected to the inner bottom wall of the limiting groove 302. The bottom of the positioning strip 300 is engaged with the interior of the limiting groove 302. The inner wall of the limiting groove 302 is slidably connected to the surface of the positioning strip 300. One end of the positioning strip 300 abuts against one side of the inner wall of the limiting groove 302. The limiting groove 302 facilitates the positioning of the positioning strip 300 during use and also helps to limit the position of the mounting ring 1, thereby facilitating the subsequent replacement of the rollers on the transmission rollers.

[0035] The limiting assembly 4 includes two bearings 400 and a threaded ring 401 sleeved on the surface of the rotating rod 301. One side of the threaded ring 401 fits against one side of the bearing 400, and the inner ring of the bearing 400 contacts the surface of the rotating rod 301. Both ends of the rotating rod 301 are threaded for threaded connection of the threaded ring 401, and one side of the upper limiting groove 302 on the rotating rod 301 is open. The threaded ring 401 is threadedly connected to the rotating rod 301 to prevent the bearings 400 from separating from the rotating rod 301 during use. This design facilitates the limiting of the bearing 400 and also facilitates the rotation of the roller. The inner ring of the bearing 400 contacts the surface of the rotating rod 301, and the inner ring hole of the bearing 400 is adapted to the rotating rod 301. One side of the threaded ring 401 does not contact the inner ring side of the bearing 400. The positioning component 3 and the limiting component 4 allow the mounting ring 1 and the polyurethane rotating ring 2 to be removed and replaced from the rotating rod 301 during use, thereby increasing the ease of replacing the conveyor roller and facilitating the operation of the operator.

[0036] The buffer assembly 5 includes a vertical plate 500 fixedly mounted on the outer ring of the bearing 400. A square tube 501 is provided at the top of the vertical plate 500. One end of the vertical plate 500 passes through the square tube 501 and extends into the interior of the square tube 501. A damping rod 502 is fixedly mounted on the inner bottom wall of the square tube 501. A positioning plate 503 is fixedly mounted on the top of the damping rod 502. The surface of the positioning plate 503 is fixedly connected to the inner wall of the square tube 501. A return spring 504 is arranged around the surface of the damping rod 502. The top of the return spring 504 is fixedly connected to the bottom of the positioning plate 503, and the bottom of the return spring 504 is fixedly connected to the inner bottom wall of the square tube 501. The return spring 504 facilitates the buffering operation of the vertical plate 500 on the positioning plate 503 during use, maintaining the overall stability. The positioning plate 503 is fixedly connected to the bottom of the vertical plate 500 inside the square tube 501. The bottom of the square tube 501 has a plate hole for the vertical plate 500 to pass through, and the inner wall of the plate hole is slidably connected to the surface of the vertical plate 500. The plate hole facilitates the passage of the vertical plate 500 during use. An mounting plate 505 is fixedly installed on the positioning plate 503. The mounting plate 505 has an oblong mounting hole. The mounting plate 505 facilitates the overall installation of the conveyor roller during use, which is convenient for subsequent use. The buffer component 5 is provided to buffer the components on the conveyor roller during use, thereby reducing the impact on the conveyor roller during travel and maintaining the stability of the conveyor roller during transmission.

[0037] Working principle: In use, the conveyor roller is installed in the desired position using the mounting plate 505. During installation, the outer ring of the bearing 400 contacts one side of the threaded ring 401. When it is necessary to replace the mounting ring 1 and polyurethane swivel ring 2 on the rotating rod 301, loosen the threaded ring 401 on one side of the rotating rod 301, thereby separating the threaded ring 401 from the rotating rod 301. Then, pull the rotating rod 301 to move it, causing one end of the rotating rod 301 to separate from one side of the bearing 400. Finally, loosen the screw 303 on the positioning strip 300. This separates the screw 303 from the positioning strip 300. Then, the mounting ring 1 is pulled out from the rotating rod 301. Next, the new mounting ring 1 is inserted into the rotating rod 301. Then, the positioning strip 300 is inserted into the limiting groove 302. After one end of the positioning strip 300 is pressed against one side of the inner wall of the limiting groove 302, the screw 303 is tightened so that the screw 303 positions and connects the mounting ring 1 on the positioning strip 300 to the rotating rod 301. One end of the rotating rod 301 is then inserted into the interior of one of the bearings 400, and the screw ring 401 is tightened.

[0038] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
