Detailed implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Refer to Figures 1-5, A convenient-to-operate abrasive polishing mechanism, including an abrasive polishing machine 100, on which there is a polishing abrasive belt 101. A connecting frame 200 is fixedly installed on the abrasive polishing machine 100. On one side of the connecting frame 200, a connecting box 201 is fixedly installed. The polishing abrasive belt 101 is movably installed in the connecting box 201. A positioning plate 202 is movably installed on the connecting box 201. On one side of the positioning plate 202, a positioning block 203 is fixedly installed. On one side of the positioning block 203, a brush 204 is fixedly installed. The brush 204 is in contact with the polishing abrasive belt 101. The brush 204 is located inside the connecting box 201. On one side of the connecting box 201, two guiding rods 300 are symmetrically and fixedly installed. At one end of each of the two guiding rods 300, a stop block 301 is fixedly installed. The same sliding plate 302 is slidably installed on the two guiding rods 300. On one side of the sliding plate 302, two insertion blocks 303 are fixedly installed. Both of the two insertion blocks 303 are movably installed on the positioning plate 202. On one side of the connecting box 201, an installation box 400 is fixedly installed. On the installation box 400, a connecting frame 401 is fixedly installed. On one side of the connecting frame 401, two motors 402 are fixedly installed. The output ends of the two motors 402 penetrate through the connecting frame 401 and are fixedly installed with fan blades 403. Inside the installation box 400, a semiconductor refrigerating sheet 404 is fixedly installed on the inner wall. On one side of the semiconductor refrigerating sheet 404, a temperature-conducting fin 405 is fixedly installed. During the process of using the abrasive polishing machine 100 and the polishing abrasive belt 101, the motor 402 can be turned on. The output end of the motor 402 will drive the fan blade 403 to rotate. When the fan blade 403 rotates, it will blow air towards the polishing abrasive belt 101 inside the connecting box 201 through the ventilation holes 406, so as to quickly blow out the dust attached to the polishing abrasive belt 101 and improve the polishing effect of the polishing abrasive belt 101. And during the use process of the polishing abrasive belt 101, it will move. During the movement of the polishing abrasive belt 101, it will contact the brush 204, so that the brush 204 can brush off the dust adhered to the polishing abrasive belt 101, further improving the polishing effect and the service life of the polishing abrasive belt 101. And the semiconductor refrigerating sheet 404 can be turned on. Since the refrigerating surface of the semiconductor refrigerating sheet 404 is in contact with the temperature-conducting fin 405, the temperature cooled by the semiconductor refrigerating sheet 404 can be conducted to the temperature-conducting fin 405. And when the fan blade 403 rotates and blows air, it will pass through the temperature-conducting fin 405, so as to blow cold air towards the polishing abrasive belt 101, achieving the effect of reducing the temperature of the polishing abrasive belt 101.

[0023] Further, a positioning groove 205 is opened on the connecting box 201. The positioning block 203 is movably installed in the positioning groove 205. Through the cooperation of the positioning block 203 and the positioning groove 205, the position deviation of the brush 204 can be avoided.

[0024] Further, two limiting slots 305 are formed in the positioning plate 202, and the two inserting blocks 303 are respectively movably installed in the two limiting slots 305. The moving inserting blocks 303 will be disengaged from the limiting slots 305 on the positioning plate 202, and at this time, the restriction on the positioning plate 202 can be released.

[0025] Further, a spring 306 is slidably sleeved on the guide rod 300. The two ends of the spring 306 are respectively fixedly installed on the sides of the stopper 301 and the sliding plate 302 close to each other. The moving sliding plate 302 will drive the two inserting blocks 303 to move and compress the spring 306 through the cooperation with the two stoppers 301, so that the spring 306 is compressed.

[0026] Further, two sliding holes 307 are formed in the sliding plate 302, and the two guide rods 300 are respectively slidably installed in the two sliding holes 307. The moving sliding plate 302 can slide on the two guide rods 300 respectively through the two sliding holes 307, thereby restricting the moving direction of the sliding plate 302.

[0027] Further, a handle 304 is fixedly installed on one side of the sliding plate 302, and an anti-slip rubber sleeve is fixedly installed on the handle 304. By providing the anti-slip rubber sleeve on the handle 304, it can be avoided that the handle 304 slips when being pulled.

[0028] Further, a ventilation hole 406 is formed in the connection box 201, and the ventilation hole 406 is communicated with the installation box 400. When the fan blade 403 rotates, it will blow air towards the polishing sand belt 101 in the connection box 201 through the ventilation hole 406.

[0029] The working principle of the present utility model:

[0030] During the process of using the abrasive polishing machine 100 and the polishing sand belt 101, the motor 402 can be turned on. The output end of the motor 402 will drive the fan blade 403 to rotate. When the fan blade 403 rotates, it will blow air towards the polishing sand belt 101 in the connection box 201 through the ventilation holes 406, so as to quickly blow out the dust attached to the polishing sand belt 101, improve the polishing effect of the polishing sand belt 101. And during the use of the polishing sand belt 101, it will move. During the movement of the polishing sand belt 101, it will contact the brush 204, so that the brush 204 can brush off the dust adhered to the polishing sand belt 101, further improving the polishing effect and the service life of the polishing sand belt 101. And the semiconductor refrigeration sheet 404 can be turned on. Since the refrigerating surface of the semiconductor refrigeration sheet 404 contacts the heat conduction fin 405, the temperature cooled by the semiconductor refrigeration sheet 404 can be conducted to the heat conduction fin 405. And when the fan blade 403 rotates and blows air, it will pass through the heat conduction fin 405, so as to be able to blow cold air towards the polishing sand belt 101, achieving the effect of reducing the temperature of the polishing sand belt 101. By pulling the handle 304, the sliding plate 302 can be driven to move. By setting an anti-slip rubber sleeve on the handle 304, it can be avoided from slipping when pulling the handle 304, so that the moving sliding plate 302 can slide on the two guide rods 300 respectively through the two sliding holes 307, thereby restricting the moving direction of the sliding plate 302. The continuously moving sliding plate 302 will drive the two plug blocks 303 to move and compress the spring 306 through the cooperation with the two stop blocks 301, so that the spring 306 is compressed. And the moving plug block 303 will disengage from the limit slot 305 on the positioning plate 202. At this time, the restriction on the positioning plate 202 can be released. By pulling the positioning plate 202, it can drive the positioning block 203 to disengage from the positioning slot 205, so that the positioning slot 205 drives the brush 204 to move out of the polishing sand belt 101, so as to replace the worn brush 204 and the positioning plate 202. Reinsert the new brush 204 and the positioning plate 202. Through the cooperation of the positioning block 203 and the positioning slot 205, the position deviation of the brush 204 can be avoided. Then release the sliding plate 302. At this time, the spring 306 in the compressed state will be released and push the sliding plate 302 to move back to its original position. The reset sliding plate 302 will drive the plug block 303 to insert into the limit slot 305 to complete the replacement and installation of the positioning plate 202.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
