[0033] See also Figure 1 - Figure 6 The present invention provides a technical solution: a surface treatment device for cemented carbide materials, comprising a housing 1, a polishing wheel 2, a motor 3, and a suction and filtering mechanism 4. The motor 3 may be a model YX3-100L1-4 motor. The housing 1 has an open front end, the polishing wheel 2 is located within the housing 1, the motor 3 is used to drive the polishing wheel 2 to rotate, and the suction and filtering mechanism 4 is used to extract air from the housing 1 and filter the extracted air. In this embodiment, the motor 3 is supported and fixed by a frame, the housing 1 is fixedly connected to the outer shell of the motor 3, the output shaft of the motor 3 passes through the housing 1 and is located within the housing 1, and the polishing wheel 2 is fixedly connected to the output shaft of the motor 3.

[0034] When using the surface treatment device for cemented carbide materials described in the present invention to treat the surface of a cemented carbide material, the motor 3 drives the polishing wheel 2 to rotate, causing the rotating polishing wheel 2 to rub against the surface of the cemented carbide material, thereby polishing the surface of the cemented carbide material. During the polishing process, the surface of the cemented carbide material is rubbed and polished, generating a large amount of dust, which is dispersed around the polishing wheel 2. During the polishing process, air within the housing 1 can be sucked in by the suction and filtration mechanism 4. During the suction and filtration mechanism 4, air outside the housing 1 can enter the housing 1 through the opening at the front end of the housing 1. After flowing through the housing 1, the air enters the suction and filtration mechanism 4. The air flowing through the housing 1 can carry dust dispersed around the polishing wheel 2 into the suction and filtration mechanism 4. The suction and filtration mechanism 4 filters the air entering the housing 1, blocking and collecting the dust within the suction and filtration mechanism 4. When the surface treatment device for cemented carbide materials described in the present invention is used to polish the surface of the cemented carbide material, the suction and filtering mechanism 4 can extract the air entering the shell 1 and filter the air extracted from the shell 1 to block and collect the dust carried in the air, thereby reducing the dust floating in the air and reducing the harm to the health of the workers.

[0035] In this embodiment, the suction and filtering mechanism 4 includes a suction assembly 41 and a filter assembly 42. One end of the suction assembly 41 is fixedly connected to the housing 1, and the other end is fixedly connected to the filter assembly 42. The suction assembly 41 is used to extract air from the housing 1 and send it to the filter assembly 42. The filter assembly 42 is used to filter the air extracted by the suction assembly 41. With this structure, the suction and filtering mechanism 4 can both suck and filter the air from the housing 1.

[0036] In this embodiment, a suction port is provided at the rear end of the shell 1, and the suction port connects the inner cavity of the shell 1 and the outer surface of the shell; the suction component 41 includes a connecting pipe 411 and a suction machine 412, and the suction machine 412 can be a fan with model CY180. One end of the connecting pipe 411 is fixedly connected to the suction port, and the other end is fixedly connected to the air inlet of the suction machine 412. The air outlet of the suction machine 412 is connected to the filter component 42.

[0037] When the suction machine 412 is turned on, it can suck the air in the housing 1 through the connecting pipe 411. Since the air outlet of the suction machine 412 is connected to the filter assembly 42, the air in the housing 1 can be sucked and sent to the filter assembly 42. When the surface treatment device for cemented carbide materials described in the present invention is used to treat the surface of cemented carbide materials, the dust generated can be sucked by the suction assembly 41 and sent to the filter assembly 42.

[0038] In this embodiment, the filter assembly 42 includes a filter box 421 and a filter plate 422. The filter plate 422 is connected to the inner wall of the filter box 421 and divides the inner cavity of the filter box 421 into a first cavity 4211 and a second cavity 4212. The filter box 421 is provided with a connection port 4213 and an exhaust port 4214. The connection port 4213 connects the first cavity 4211 with the outer surface of the filter box 421, and the exhaust port 4214 connects the second cavity 4212 with the outer surface of the filter box 421. The air outlet of the suction machine 412 is connected to the connection port 4213. In this embodiment, the filter plate 422 includes a fixing plate and a filter element. The fixing plate has a mounting hole in the middle. The filter element is fixedly connected to the mounting hole and seals the mounting hole. The filter element is used to filter dust in the air flowing from the first cavity 4211 to the second cavity 4212.

[0039] Air sucked by the suction assembly 41 enters the first cavity 4211 through the connection port 4213, then flows through the filter plate 422 into the second cavity 4212, and finally is exhausted through the exhaust port 4214. As the air flows through the filter plate 422, it filters dust in the air, reducing the dust content in the air entering the second cavity 4212 and exiting the filter box 421. This reduces the amount of dust floating in the air when the cemented carbide material surface treatment device of the present invention is used to polish the surface of the cemented carbide material.

[0040] In this embodiment, a strip-shaped hole 4215 is provided on the filter box 421 . The strip-shaped hole 4215 is matched with a vertical end of the filter plate 422 . The filter plate 422 is slidably disposed in the strip-shaped hole 4215 .

[0041] After prolonged use of the cemented carbide material surface treatment device described in the present invention, a large amount of dust will adhere to the filter plate 422, necessitating cleaning of the filter plate 422. Pulling the filter plate 422 outward allows the filter plate 422 to be pulled out of the filter box 421 through the strip-shaped holes 4215, thereby cleaning the dust adhered to the filter plate 422. After cleaning the filter plate 422, aligning the filter plate 422 with the strip-shaped holes 4215 and pushing the filter plate 422 into the filter box 421 allows the filter plate 422 to be reinstalled within the filter box 421.

[0042] In this embodiment, the filter plate 422 is connected to a handle at the strip hole 4215. When the filter plate 422 is taken out from the filter box 421, the handle can be used to pull the filter plate 422, which is more convenient when taking the filter plate 422 out of the filter box 421.

[0043] In this embodiment, the filter assembly 42 also includes a first plate body 423 and a second plate body 424. The first plate body 423 and the second plate body 424 are both fixedly connected to the filter box 421. The first plate body 423 and the second plate body 424 respectively support the two opposite sides of the filter plate 422. A first through hole is formed in the middle of the first plate body 423, and a second through hole is formed in the middle of the second plate body 424. The first through hole is opposite to the second through hole, and the filter plate 422 closes the first through hole and the second through hole.

[0044] When the filter plate 422 is installed in the filter box 421, the first plate body 423 and the second plate body 424 are pressed against two opposite sides of the filter plate 422. When the suction machine 412 delivers air to the first cavity 4211 and the air flows from the first cavity 4211 to the second cavity 4212, the filter plate 422 can remain stable and the filter plate 422 is not likely to tilt.

[0045] In this embodiment, the bottom wall of the first cavity 4211 is inclined, and the end close to the filter plate 422 is the high end; the filter assembly 42 also includes a dust exhaust pipe 426 and a valve 427, the dust exhaust pipe 426 is connected to the first cavity 4211, and is located at the low end of the bottom wall of the first cavity 4211, and the valve 427 is arranged on the dust exhaust pipe 426.

[0046] After prolonged use of the cemented carbide material surface treatment device described in the present invention, the filter plate 422 filters dust in the air flowing through the filter plate 422, and dust is deposited on the bottom wall of the first cavity 4211. Because the bottom wall of the first cavity 4211 is tilted, and because the dust exhaust pipe 426 is connected to the lower end, when it is necessary to discharge the deposited dust, it is only necessary to open the valve 427 and then tap the filter box 421. The vibration of the filter box 421 can cause the dust deposited on the bottom wall of the first cavity 4211 to slide toward the lower end and then be discharged from the dust exhaust pipe 426. This structure makes it more convenient to discharge the dust deposited in the first cavity 4211.

[0047] In this embodiment, the surface treatment device for cemented carbide materials described in the utility model further includes a second cleaning brush 5 , which is fixedly connected to the housing 1 , and the bristles of the second cleaning brush 5 abut against the outer peripheral surface of the polishing wheel 2 .

[0048] During the surface polishing process of the cemented carbide material, the polishing wheel 2 may generate static electricity, and then the dust generated during the polishing process is adsorbed on the outer peripheral surface of the polishing wheel 2. If too much dust is adsorbed on the outer peripheral surface of the polishing wheel 2, it will affect the polishing effect of the surface of the cemented carbide material. In this embodiment, the bristles of the second cleaning brush 5 are against the outer peripheral surface of the polishing wheel 2. When the polishing wheel 2 rotates, the second cleaning brush 5 can clean the dust adsorbed on the outer peripheral surface of the polishing wheel 2, reducing the amount of dust adsorbed on the outer peripheral surface of the polishing wheel 2 during the polishing process, that is, it can reduce the impact of the outer peripheral surface of the polishing wheel 2 adsorbing a large amount of dust on the polishing effect of the surface of the cemented carbide material.

[0049] Example 2

[0050] See also Figure 7 - Figure 9 , Example 2 is only a preferred embodiment of Example 1, and the implementation of Example 2 will not affect the independent implementation of Example 1.

[0051] The difference between this embodiment and the first embodiment is that the filter assembly is further provided with a first cleaning brush, and the rest of the parts are the same as those of the first embodiment.

[0052] Specifically: the filter assembly 42 further includes a first cleaning brush 425, which is disposed in the first through hole and located at one end of the first through hole close to the bar-shaped hole 4215. The bristles of the first cleaning brush 425 abut against the filter plate 422. Figure 9The first cleaning brush 425 includes a connecting plate fixed in the first through hole, and bristles (not shown in the figure) are provided on the side of the connecting plate facing the second through hole, and one end of the bristles close to the second through hole is pressed against the filter plate 422.

[0053] After prolonged use of the cemented carbide material surface treatment device described in the present invention, a large amount of dust adheres to the filter plate 422, requiring cleaning. By pulling the filter plate 422 outward, the bristles of the first cleaning brush 425 can brush off the dust adhering to the side of the filter plate 422 facing the first cavity 4211 as the filter plate 422 slides outward, thereby cleaning the filter plate 422. The brushed-off dust falls onto the bottom wall of the first cavity 4211. By repeatedly pulling and pushing the filter plate 422, the bristles of the first cleaning brush 425 can repeatedly brush off the dust on the side of the filter plate 422 facing the first cavity 4211. When cleaning the filter plate 422, the filter plate 422 does not need to be completely removed from the filter box 421, making it more convenient to clean the dust adsorbed on the filter plate 422.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
