The utility model is used in coordination with the workbench, the grinder body, the support plate, the cylinder, the protective plate and the dustproof mechanism. ";

[0032] The existing grinder with a protective structure is easy to cause harm to the user when using the grinder to cut hard materials, and when grinding objects that are easy to generate dust, the worker is easy to cause harm to the body when using the grinder. This problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, an adaptive clamping structure and dust suction and noise reduction functions are added to this application document.

[0033] According to the above content, in order to facilitate the user's safe use and more conveniently clamp the material 503.

[0034] In this embodiment: a slide groove is opened inside the base 3, and a lifting plate 301 is slidably connected inside the slide groove of the base 3. An arc groove is opened on the left side of the top of the lifting plate 301, and a threaded rod 303 is slidably connected inside the arc groove of the lifting plate 301. A bolt cap 302 is sleeved on the outer side of the threaded rod 303, and the bolt cap 302 fits on the top of the base 3.

[0035] In an optional embodiment: a second spring 304 is sleeved on the outer side of the threaded rod 303 , and a brush 305 is tightly arranged on the bottom end of the second spring 304 .

[0036] In this embodiment: a slide groove is opened inside the base 1, a conveyor belt 101 is attached to the inside of the slide groove of the base 1, the top of the conveyor belt 101 is attached to the material 503, the top of the base 1 is fixedly connected to the first support frame 102, a connecting pipe 502 runs through the left side of the first support frame 102, and the left side of the connecting pipe 502 is sleeved with a collection box 5.

[0037] In an optional embodiment: a cavity is opened inside the collection box 5, a drawer 501 is arranged inside the cavity of the collection box 5, the drawer 501 is slidably connected inside the cavity of the collection box 5, and the bottom end of the collection box 5 is fixedly connected to the second support frame 103.

[0038] In this embodiment: after grinding the material 503, the waste chips generated are sucked into the collection box 5 through the connecting pipe 502 by the fan 401 at the top of the air collecting box 4. After a period of time, the drawer 501 inside the collection box 5 is opened to clean up the waste chips.

[0039] In an optional embodiment: the top of the first support frame 102 is fixedly connected to the air collecting box 4, the bottom of the air collecting box 4 is provided with an air inlet, the top of the air inlet of the air collecting box 4 is attached with a fan 401, and two groups of fans 401 are provided.

[0040] In this embodiment: after running for a period of time, the cover plate 402 at the top of the air collecting box 4 is opened, and the internal fan 401 is cleaned, and the cover plate 402 is attached to the top of the air collecting box 4 by the rotating block 403.

[0041] The working principle and use process of the utility model are as follows: first, the staff installs the base 1 on a flat ground, installs the conveyor belt 101 on the top of the base 1 and fixes it, installs the first support frame 102 on the right side of the top of the base 1, installs the second support frame 103 on the left side of the top of the base 1, and installs the base 3 on the right side of the first support frame 102 and fixes it with bolts. After the installation is completed, the material 503 is placed on the top of the conveyor belt 101, and according to the height of the material 503, the lifting plate 301 is moved upward, the height of the lifting plate 301 is adjusted, and the bolt cap 302 is rotated counterclockwise to tighten the bolt cap 302. 2 creates a gap with the lifting plate 301, thereby causing looseness. At this time, according to the width of the material 503, the threaded rod 303 is moved inside the lifting plate 301, and the brush 305 at the bottom of the threaded rod 303 is close to the material 503. When the material 503 fits the brush 305, the rotating brush 305 rubs the material 503. When encountering large burrs, the brush 305 slides upward again, and slides downward under the pressure of the second spring 304 at the top of the brush 305, thereby preventing the material 503 from impacting the brush 305, thereby protecting the brush 305 from damage and increasing the service life of the brush 305.

[0042] Then, the fixing plate 2 is installed on the outer side of the first support frame 102, the ring 202 is installed in the circular hole inside the fixing plate 2, the central rotating shaft 201 is inserted into the inside of the ring 202, and the roller brush 203 is inserted on the outer side of the central rotating shaft 201. When the material 503 is transferred to the top of the roller brush 203 on the conveyor belt 101, the material 503 lifts up the roller brush 203. At this time, the ring 202 slides upward in the circular groove inside the fixing plate 2. At this time, the lower nut 208 presses against the first spring 205 to slide upward, and presses against the shock-absorbing plate 206 at the top of the first spring 205. At this time, the shock-absorbing plate 206 damps the first spring 205, and the height of the telescopic rod 204 can be adjusted according to the size of the material 503. By rotating the upper nut 207 on the top of the shock-absorbing plate 206 clockwise, the stroke of the first spring 205 is reduced, and the range of the roller brush 203 is reduced.

[0043] After the material 503 is polished, the waste chips generated are sucked into the collection box 5 through the connecting pipe 502 by the fan 401 at the top of the air collecting box 4. After a period of time, the drawer 501 inside the collection box 5 is opened to clean up the waste chips. After running for a period of time, the cover 402 at the top of the air collecting box 4 is opened, and the fan 401 inside is cleaned, and the cover 402 is attached to the top of the air collecting box 4 by rotating the block 403.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
