Technical Field

[0001] This utility model belongs to the field of dumbbell counterweight processing technology, specifically a polishing device for processing dumbbell counterweights. Background Technology

[0002] Dumbbells are a type of fitness equipment used for strength training. Based on their adjustment method, dumbbells can be divided into fixed-weight dumbbells and adjustable-weight dumbbells. Fixed-weight dumbbells have a fixed weight, such as 5kg or 10kg dumbbells. These dumbbells are relatively simple to manufacture and are quite durable. Adjustable-weight dumbbells, on the other hand, allow users to change the weight by adding or removing weights. Their advantage lies in their ability to flexibly adjust the weight according to the user's strength training needs at different stages, saving space and cost, as it eliminates the need to purchase multiple sets of fixed dumbbells of different weights.

[0033] Furthermore, the conveying platform 2 includes a correspondingly arranged active roller 201 and driven roller 202, a conveyor belt 203 connecting the active roller 201 and driven roller 202, and a motor 204 connected to one end of the active roller 201 via a motor shaft.

[0034] Furthermore, a positioning groove 6 is provided on the conveyor belt 203 at the position corresponding to the protective cylinder 401, and an anti-slip pad is provided on the inner wall of the positioning groove 6.

[0035] It is worth noting that the movable frame 302 includes a base plate 3021. The top plate 3023 is connected to the four corners of the top of the base plate 3021 by support rods 3022. The gear 303 is installed on the base plate 3021. The drive motor 304, the chip collection box 406, and the fan 407 are all located on the top plate 3023.

[0036] It is worth noting that the bottom of the protective cylinder 401 is provided with an air inlet 7, and the protective cylinder 401 is provided with a through hole 8 at the position corresponding to the rotating rod 305.

[0039] Working principle and process: The dumbbell counterweight is placed in the positioning groove 6. The motor 204 of the conveyor platform 2 is started, which in turn drives the conveyor belt 203 to rotate in conjunction with the driven roller 202 until the dumbbell counterweight is conveyed to the bottom of the protective cylinder 401. The drive motor 304 of the grinding assembly 3 is started, which in turn drives the grinding block 306 to rotate in conjunction with the gear 303. Subsequently, the cylinder 301 is started, which retracts, thereby moving the movable frame 302 downward. The protective cylinder 401 is the first to contact the positioning groove 6, causing... The spring telescopic rod 402 retracts, causing the grinding block 306 to continuously move downwards until it contacts the dumbbell counterweight, allowing for grinding and polishing. Simultaneously, the fan 407 of the chip removal assembly 4 is activated, allowing outside air to enter through the air inlet 7. This air carries debris through the air intake 403, air duct 404, and hose 405 into the chip collection box 406, where it is trapped by the filter screen. This completes the cleaning of the debris. Furthermore, the protective cylinder 401, in conjunction with the positioning groove 6, reduces noise transmission, which is beneficial for the use of the device.
