Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a dust-proof cutting machine. Background Art

[0002] The body of the cutting machine has a circular cutting blade that rotates driven by an electric motor. The outer shell of the body is provided with a smooth flat plate for cooperating with the surface of the workpiece. The rotating shaft of the cutting blade is parallel to the smooth flat plate, and the lower part of the cutting blade extends out from the smooth flat plate. Then, the extending part of the cutting blade is used to cut the workpiece. The upper edge of the cutting blade is covered by a body cover, and the outer end of the body cover is of an open structure, so that the outer cutting surface of the cutting blade is exposed outside. A large amount of dust is generated during cutting and scattered in the working space. The generated dust causes great harm to the human body. And to ensure safety, the cutting machine is generally fixedly installed on an operating frame. However, the height of the operating frame is fixed, which is relatively inconvenient to use.

[0022] In this embodiment, the dust removal mechanism 3 includes a plurality of ash inlets 301, two communication ports 302, two filter boxes 303, two filter screens 304, a three-way pipe 306 and a fan 307. The opposite sides of the two filter boxes 303 are fixedly connected to the left and right sides of the workbench 1. The upper parts of the opposite sides of the two filter boxes 303 are connected to the inside of the workbench 1 through the communication ports 302. A plurality of ash inlets 301 are equally spaced on the upper part of the workbench 1. The filter screens 304 are arranged outside the middle and lower parts of the filter boxes 303. Two ends of the three-way pipe 306 are connected to the lower parts of the two filter boxes 303, and the other end of the three-way pipe 306 is installed at the input end of the fan 307. The fan 307 is installed on the upper part of the bottom plate 5. A sewage discharge valve 308 is arranged on the lower side of the front part of the workbench 1. Filter water is arranged inside the workbench 1. A maintenance door 305 is arranged on the front part of the filter box 303.

[0023] Specifically, drive the fan 307 to extract the air inside the filter box 303 through the three-way pipe 306, so that the inside of the filter box 303 is in negative pressure. When cutting an object, the dust generated during cutting carried by the outside air enters the inside of the workbench 1. Most of the dust will settle inside the workbench 1 and combine with the filter water to prevent it from floating. The remaining small amount of dust enters the inside of the filter box 303 through the communication port 302, effectively preventing the dust during cutting from floating around and protecting the operating environment.

[0024] In this embodiment, the lifting mechanism 4 includes a limiting tube 401, a limiting rod 402, a sleeve 403, a threaded rod 404 and a driving assembly. The lower part of the limiting tube 401 is fixedly connected to the upper corners of the four corners of the bottom plate 5. The outer circumference of the limiting rod 402 is slidably connected to the inside of the limiting tube 401. The upper end of the limiting rod 402 is fixedly connected to the lower corners of the four corners of the workbench 1. The lower end of the sleeve 403 is fixedly connected to the middle of the bottom plate 5. The upper end of the threaded rod 404 is fixedly connected to the lower side of the middle of the workbench 1. The lower part of the threaded rod 404 is arranged inside the sleeve 403. The driving assembly is installed on the upper part of the sleeve 403 and is connected to the threaded rod 404. The driving assembly includes a fixed box 405, a reduction motor 406, a gear 407 and a toothed ring 408. The lower part of the fixed box 405 is installed on the upper part of the sleeve 403. The upper part of the reduction motor 406 is installed on the lower part of the fixed box 405. The gear 407 and the toothed ring 408 are meshed with each other and installed inside the fixed box 405. The driving end on the upper side of the reduction motor 406 penetrates through the fixed box 405 and is fixedly connected to the middle of the gear 407. The middle of the toothed ring 408 is threadedly connected to the outside of the threaded rod 404. Universal wheels 6 are arranged at the four corners of the lower part of the bottom plate 5.

[0025] Specifically, through the limitation of the limiting tube 401 and the limiting rod 402, the workbench 1 cannot rotate. Then, the reduction motor 406 is driven, so that the gear 407 drives the toothed ring 408 to rotate, so that the threaded rod 404 can drive the workbench 1 to move up and down, and thus the height of the workbench 1 can be adjusted, which is convenient for cutting operations on objects.

[0026] Working principle:

[0027] The blower 307 is driven to extract the air inside the filter box 303 through the three-way pipe 306, so that the inside of the filter box 303 is in negative pressure. When cutting an object, the dust generated during cutting carried by the outside air enters the inside of the workbench 1. Most of the dust will settle inside the workbench 1 and combine with the filtering water to prevent it from floating. The remaining small part of the dust enters the inside of the filter box 303 through the communication port 302, effectively preventing the dust during cutting from floating around and protecting the operating environment. Through the limitation of the limiting tube 401 and the limiting rod 402, the workbench 1 cannot rotate. Then, the reduction motor 406 is driven, so that the gear 407 drives the toothed ring 408 to rotate, so that the threaded rod 404 can drive the workbench 1 to move up and down, and thus the height of the workbench 1 can be adjusted, which is convenient for cutting operations on objects.

Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the descriptions in the specification are only used to illustrate the principles of the present utility model.
