[0002] Sprocket conveyor rollers are widely used in material conveying systems. They consist primarily of a roller body and a sprocket. These conveyor rollers utilize the sprocket to drive the roller's rotation, thereby conveying the material placed on the roller. Combining the accuracy of a sprocket drive with the stability of a roller conveyor, they are suitable for a variety of industrial applications requiring precise control of conveying speed and direction.

[0003] As disclosed in the utility model with application number 202221903099.2, it is specifically a quick-release sprocket roller. The designed disassembly and assembly components facilitate the disassembly and installation of the end shaft and the roller.

It is simple and easy to operate and has good practicality.

[0004] Similar to the above application, there are still some deficiencies:

[0005] This type of connection between the gear roller end and the sprocket may not be stable enough. The sprocket is prone to loosening during long periods of high load operation or when subjected to large impacts. The connecting key between the sprocket and the roller may wear or loosen, resulting in poor synchronization between the sprocket and the roller, affecting conveying accuracy and making installation more complicated.

[0006] For this reason, a sprocket conveyor roller is designed to optimize the above-mentioned problem. Utility Model Content

[0013] Preferably, a reinforcement layer is provided on the outer side of the limiting rod, a bearing is provided between the mounting cylinder and the mounting tube, and limiting strips are evenly provided on the outer side of the mounting cylinder.

[0014] Preferably, the blocks are all fan-shaped blocks, and anti-slip strips are provided on both sides of the blocks.

[0015] The beneficial effects of the utility model are:

[0016] The utility model provides a sprocket conveyor roller, which, through the coordinated use of an outer cylinder, a fixed cylinder, a mounting cylinder, a mounting tube, a rotating shaft, a mounting groove, a first spring, a limiting rod, a fixing ring, a through hole, a T-shaped rod and a second spring, can utilize the action of the limiting rod and the first spring to simultaneously limit the mounting cylinder and the fixing ring, thereby making the fixing ring and the mounting cylinder more stable after installation and more convenient to disassemble and install, thereby improving the convenience of the sprocket conveyor roller;

[0017] By using the positioning groove and the positioning block in combination, when the installation tube is inserted into the interior of the outer tube, the positioning groove at the end of the installation tube is aligned with the positioning block, so that the positioning block is inserted into the interior of the positioning groove, and then the installation tube is quickly positioned, so that subsequent installation work can be carried out quickly, which can improve the efficiency of the installation work and meet the use needs of the staff;

[0018] By cooperating with the clamping block, the internal threaded ring and the stopper, when the mounting cylinder moves to the inside of the outer cylinder, the mounting cylinder drives the clamping block to move until the clamping block and the stopper are staggered, and the clamping block moves to the right side of the stopper. Then the internal threaded ring is rotated, and the internal threaded ring drives the stopper to move the clamping block and the mounting cylinder to the right side, which limits the mounting cylinder, thereby further improving the stability between the mounting cylinder and the fixing ring.
