[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1-6 As shown, a jewelry processing and polishing device includes a mounting box 1, a transparent cover 6 mounted on the mounting box 1, an adjustment structure 2 on the mounting box 1, an adjustment plate 201 slidably connected to the mounting box 1, two guide rails 202 fixedly connected to the mounting box 1, the adjustment plate 201 slidably connected to the guide rails 202, a polishing structure 5 on the adjustment plate 201, the adjustment plate 201 slidably connected to the transparent cover 6, a connecting block 203 fixedly connected to the adjustment plate 201, a mounting shaft 204 rotatably connected to the connecting block 203, a stop block 206 fixedly connected to the mounting shaft 204, and a fixing groove 207 on one of the guide rails 202, with the stop block 206 located in the fixing groove 207.
[0019] As a technical optimization of this utility model, the guide rail 202 has a trapezoidal structure, and a torsion spring 205 is fixedly connected between the mounting shaft 204 and the connecting block 203. The grinding structure 5 includes a drive shaft 501, which is rotatably connected to the adjusting plate 201. A grinding brush 502 is detachably connected to the drive shaft 501. The driving component 503 (preferably a motor) on the adjusting plate 201 drives the drive shaft 501 to rotate, and the drive shaft 501 drives the detachably connected grinding brush 502 to rotate at high speed. Jewelry can be held directly to the polishing brush 502 for polishing. The detachable connection between the polishing brush 502 and the drive shaft 501 makes the replacement of the polishing brush 502 more flexible. Operators can quickly change the corresponding type of polishing brush 502 according to different needs such as coarse grinding and fine grinding of jewelry, thereby improving the processing adaptability. A cam 504 is fixedly connected to the drive shaft 501, and a drive component 503 is installed on the adjusting plate 201. The drive shaft 501 is driven by the drive component 503.
[0020] As a technical optimization of this utility model, the mounting box 1 is provided with a dust collection structure 3, which includes a grid plate 301. The grid plate 301 is fixedly connected to the mounting box 1, and a drawer 302 is slidably connected to the mounting box 1. A sliding frame 303 is slidably connected inside the mounting box 1, and a filter screen 304 is fixedly connected to the sliding frame 303. The vacuum cleaner 306 inside the mounting box 1 draws air from the mounting box 1 through the air extraction pipe 305, creating a negative pressure inside the mounting box 1. Dust is trapped under the negative pressure. The dust is adsorbed onto the filter screen 304, which is fixed on the sliding frame 303. This effectively intercepts dust and prevents it from entering the vacuum cleaner 306 and causing damage to the equipment. At the same time, it ensures the cleanliness of the exhaust air and meets environmental protection requirements. The vacuum cleaner 306 is installed inside the mounting box 1. An air extraction pipe 305 is fixedly connected between the suction port of the vacuum cleaner 306 and the mounting box 1. The air extraction pipe 305 is connected to the upper side of the filter screen 304. A first spring 307 is fixedly connected between the sliding frame 303 and the mounting box 1.
[0021] As a technical optimization of this utility model, the sliding frame 303 is driven by a linkage structure 4. The linkage structure 4 includes a sliding rod 401, which is fixedly connected to the sliding frame 303. A connecting shaft 402 is rotatably connected to the sliding rod 401. A connecting rod 403 is fixedly connected to the connecting shaft 402. A fixed shaft 408 is fixedly connected to the connecting rod 403. A roller 409 is fixedly connected to the fixed shaft 408. The roller 409 rolls with the cam 504. The fixed rod 404 is slidably connected to the sliding rod 401. Driven by the cam 504, the sliding frame 303 moves through the connecting rod 403 and the sliding rod 401. The roller 409 connected to the fixed shaft 408 by the connecting rod 403 rolls with the cam 504. This rolling engagement reduces frictional loss between the two components, thus reducing... Low noise, while ensuring smooth power transmission, the rotation of cam 504 is converted into the reciprocating up and down movement of connecting rod 403, which in turn drives sliding frame 303 to reciprocate up and down through slide rod 401. The reciprocating movement of slide frame 303 causes filter screen 304 to vibrate, and the dust attached to the surface of filter screen 304 falls off into drawer 302 under the action of vibration. Drawer 302 is slidably connected to mounting box 1. Operators can periodically pull out drawer 302 to clean dust. The operation is simple and convenient, avoiding the filter screen 304 from clogging and affecting the dust collection effect. A vertical rod 406 is fixedly connected to the fixed rod 404, and a limit rod 407 is fixedly connected to the vertical rod 406. The limit rod 407 engages with the square hole on connecting shaft 402. A second spring 405 is fixedly connected between fixed rod 404 and slide rod 401.
[0022] In use, when the polishing brush 502 needs to be replaced, the operator only needs to move the mounting shaft 204. The mounting shaft 204 rotates on the connecting block 203 and drives the stop block 206 to disengage from the fixing groove 207 on the guide rail 202. At this time, the adjusting plate 201 can slide freely along the guide rail 202, and the torsion spring 205 fixedly connected between the mounting shaft 204 and the connecting block 203 will generate an elastic force. The adjusting plate 201 and the polishing brush 502 slide out of the transparent cover 6 as a whole, avoiding the transparent cover 6 from obstructing the polishing assembly and affecting the operation. This greatly reduces the difficulty of maintenance and replacement of the polishing assembly and saves replacement time. After the polishing brush 502 is installed, the adjusting plate 201 is slid to the designated position, and the torsion spring 205 can drive the stop block 206 to automatically... The device resets and snaps into the fixing slot 207, quickly achieving the positioning and fixation of the adjusting plate 201 without the need for additional tools, making operation convenient and efficient. After starting the device, the driving component 503 (preferably a motor) on the adjusting plate 201 drives the transmission shaft 501 to rotate. The transmission shaft 501 drives the detachably connected polishing brush 502 to rotate at high speed. The operator can hold the jewelry to the polishing brush 502 and polish it by the rotating polishing brush 502. The detachable connection between the polishing brush 502 and the transmission shaft 501 makes the replacement of the polishing brush 502 more flexible. The operator can quickly change the corresponding type of polishing brush 502 according to different needs such as coarse grinding and fine grinding of jewelry, improving processing adaptability. At the same time, the cam 504 fixedly connected to the transmission shaft 501 moves with the jewelry. The drive shaft 501 rotates synchronously. During the polishing operation, the grating plate 301 on the top of the mounting box 1 supports the jewelry to be polished, while allowing the dust generated during polishing to fall into the mounting box 1 through the grating plate 301, preventing dust accumulation on the operating surface from affecting processing. The vacuum cleaner 306 inside the mounting box 1 draws air from the mounting box 1 through the suction pipe 305, creating a negative pressure inside the mounting box 1. Under the action of negative pressure, the dust is adsorbed to the filter screen 304. The filter screen 304 is fixed on the sliding frame 303, which can effectively intercept dust and prevent dust from entering the vacuum cleaner 306 and causing equipment damage, while ensuring the cleanliness of the exhaust air and meeting environmental protection requirements. The first spring 307, which is fixedly connected between the sliding frame 303 and the mounting box 1, provides the reciprocating motion of the sliding frame 303. The elastic restoring force, driven by the cam 504, moves the sliding frame 303 through the connecting rod 403 and the slide rod 401. The connecting rod 403, connected to the roller 409 via the fixed shaft 408, rolls with the cam 504. This rolling engagement reduces friction loss and noise while ensuring smooth power transmission. The rotation of the cam 504 is converted into the reciprocating up-and-down movement of the connecting rod 403, which in turn drives the sliding frame 303 to reciprocate up-and-down through the slide rod 401. The reciprocating movement of the sliding frame 303 causes the filter screen 304 to vibrate, causing dust adhering to the surface of the filter screen 304 to fall into the drawer 302. The drawer 302 is slidably connected to the mounting box 1, allowing operators to periodically remove the drawer 302 to clean the dust. The operation is simple and convenient.To prevent filter 304 from clogging and affecting vacuuming performance, and to further enhance the cleaning effect, when the adjusting plate 201 slides out, simply pull the fixing rod 404 to compress the second spring 405. This will cause the vertical rod 406 to move the limiting rod 407 out of the square hole, unlocking the connecting shaft 402. At this point, rotating the connecting rod 403 to a vertical position will not affect the sliding out of the adjusting plate 201. Simultaneously, because the roller 409 disengages from the cam 504, the reciprocating sliding of the sliding frame 303 can be stopped.
