Technical Field
[0001] This utility model relates to the field of gear technology, and in particular to a rubber wheel with pointed teeth for a belt sander used for polishing. Background Technology
[0002] The toothed rubber wheel of a sand mill is a key component, playing a crucial role in the grinding process. During operation, the toothed rubber wheel works in conjunction with the grinding media (such as glass beads, ceramic beads, etc.) to grind material particles into finer particles through rotation and friction. However, after prolonged use, frequent friction between the rubber wheel surface and the grinding media and materials, along with the hardness and shape of the grinding media and the properties of the materials (such as particle size and hardness), causes the rubber on the wheel surface to gradually wear down, resulting in a thinner rubber layer and affecting the wheel's performance and lifespan. Furthermore, the teeth may deform under significant compressive and shear forces, affecting the driving force on the grinding media and the grinding effect on the material. Besides selecting rubber materials with good wear resistance, replacing the rubber wheel can ensure grinding effectiveness and extend its service life. Therefore, this invention proposes a toothed rubber wheel for a sander belt polisher. Utility Model Content

[0026] like Figure 1-6 As shown, a rubber wheel with pointed teeth for a belt sander for polishing includes a hub 1, with rubber pointed teeth detachably fitted around the outer periphery of the hub 1. Each rubber pointed tooth includes a tooth tip 2 and a clamping part 3. A boss 201 is integrally formed on the inner sidewall of the tooth tip 2. One side of the hub 1 is inserted into the boss 201, and the other side is connected to the clamping part 3 via a quick-release assembly 4. The outer sidewall of the clamping part 3 abuts against the inner sidewall of the tooth tip 2. Several anti-rotation blocks 5 are installed between the tooth tip 2 and the hub 1. The anti-rotation blocks 5 prevent relative rotation between the hub 1 and the tooth tip 2, thus providing a fixing function. With the cooperation of the quick-release assembly 4, the clamping part 3 secures the hub 1 and the tooth tip 2, thereby achieving detachable installation between the hub 1 and the rubber pointed teeth.
[0027] The hub 1 includes a hub body 101, the bottom of which has a groove 102 that mates with the boss 201. The upper end of the hub body 101 has several anti-rotation grooves 103 that match the anti-rotation blocks 5. The anti-rotation block 5 includes an anti-rotation protrusion 501 and an integrally formed anti-rotation strip 502. The anti-rotation protrusion 501 is inserted into the hub 1, and the anti-rotation strip 502 is inserted into the tooth tip 2. The top of the tooth tip 2 has an anti-rotation groove 203 that mates with the anti-rotation strip 502. The anti-rotation protrusion 501 is inserted into the anti-rotation groove 103, and the anti-rotation strip 502 is inserted into the anti-rotation groove 203, enabling quick positioning and installation between the hub 1 and the tooth tip 2, preventing mutual rotation, improving connection stability, and ensuring reliability in subsequent operations.
[0028] A positioning block is installed on the outer side wall of the clamping part 3, and a positioning groove 202 that cooperates with the positioning block is opened on the inner side wall of the tooth tip 2. The positioning block is inserted into the positioning groove 202, which not only allows for quick positioning and installation, but also prevents mutual rotation between the clamping part 3 and the tooth tip 2.
[0029] The quick-release assembly 4 includes a fixed wedge 401 mounted on the hub 1. A slider 403 is integrally formed on the inclined surface of the fixed wedge 401. A groove 404 is slidably mounted on the slider 403, and a movable wedge 405 is integrally formed on the groove 404. During installation, the groove 404 slides into the slider 403, and a tight connection is achieved using the compressive force generated by the inclined surface of the wedge. The end of the movable wedge 405 away from the fixed wedge 401 is integrally formed with a connecting end 407, which is fixedly connected to the inner wall of the clamping part 3. A long through hole 406 is provided at the upper end of the movable wedge 405, and a bolt assembly is installed within the long through hole 406.

[0030] The fixed end 402 is integrally formed at the end of the fixed wedge block 401 away from the movable wedge block 405, and the fixed end 402 is connected to the hub 1 by screws.
[0031] The installation process of this utility model's toothed rubber wheel is as follows:
[0032] First, the groove 102 of the hub 1 rests on the boss 201 of the tooth tip 2, and the hub 1 is rotated so that the first anti-rotation groove 103 and the second anti-rotation groove 203 are in the same position; then, the anti-rotation block 5 is inserted into the first anti-rotation groove 103 and the second anti-rotation groove 203 to achieve quick positioning and installation of the hub 1 and the tooth tip 2; after that, the fixing wedge 401 is fixed to the threaded connection hole on the hub 1 through the fixing end 402, and the sliding groove 404 on the moving wedge 405 slides along the slider 403. During the movement, the connecting end 407 drives the pressing part 3 to move towards the inner wall of the tooth tip 2 until it presses against the tooth tip 2. Finally, the fixing wedge 401 and the moving wedge 405 are connected together by the bolt assembly to fix the pressing part 3. Under the action of the pressing part 3, the hub 1 and the tooth tip 2 are fixed. In this embodiment, the number of pressing parts 3 is determined according to the actual situation. Several pressing parts 3 are combined into a ring structure, and the outer diameter of the ring structure is consistent with the inner diameter of the tooth tip 2.
