The negative pressure component 105 can use a vacuum pump. The vacuum pump can generate a higher negative pressure than a general fan or vacuum cleaner, which can improve the dust collection efficiency. The dust box 103 is provided with a scraper component for scraping dust off the surface of the filter 104. It should be noted here that the dust pipe 102 should have some length reserved so that the spindle and the tool on the engraving machine can work normally. This is a prior art well known in the art, and this embodiment does not impose too many restrictions on this.

[0024] By means of the dust suction mechanism, when the engraving machine is working, the negative pressure component 105 can be started to generate negative pressure inside the dust box 103. Under the action of air pressure, dust enters the dust box 103 through the dust suction pipe 102. The filter 104 can intercept dust to prevent it from entering the negative pressure component 105 and causing damage. The dust suction mechanism can timely remove dust and waste generated during the engraving machine processing, keep the working environment clean, and reduce the impact of dust on the equipment and the operator. At the same time, the dust suction mechanism can prevent dust from accumulating on the tool or the spindle, thereby improving the cutting ability of the tool and reducing the processing quality. The scraper component can facilitate the staff to regularly filter the dust accumulated on the surface of the filter 104, thereby maintaining the permeability of the filter 104 and the dust suction efficiency of the dust suction mechanism.

[0025] In this embodiment, in order to facilitate the staff to remove the filter 104, a mounting groove 2 is provided on the top of the dust box 103, baffles 201 are provided on both sides of the mounting groove 2, and a mounting frame 202 is provided on the top of the filter 104. The bottom of the mounting frame 202 abuts against the baffle 201, and the mounting frame 202 is slidably connected to the inner wall of the mounting groove 2. A first handle 203 is provided on the top of the mounting frame 202. The mounting groove 2 can facilitate the staff to remove the filter 104, and the first handle 203 can facilitate the staff to apply The filter 104 is pulled out by torque. When the filter 104 is placed in the installation groove 2, the baffle 201 can provide a support point, so that the filter 104 can be placed inside the dust box 103 by its own gravity. In order to make the filter 104 placed more stably, a vacuum groove 204 is provided on the side of the dust box 103 away from the dust pipe 102, and a fixing block 205 is provided on the side of the vacuum groove 204 close to the dust pipe 102. The fixing block 205 is provided with a fixing groove 206, and the bottom of the filter 104 abuts against the bottom of the fixing groove 206.

[0026] The fixed groove 206 can form a support point at the bottom of the filter 104, thereby improving the stability of the dust collection mechanism during operation. Secondly, a sealing gasket can be set on the inner wall of the installation groove 2 to increase the sealing of the dust collection box 103, thereby improving the dust collection effect.

[0027] When the staff needs to disassemble, they only need to hold the first handle 203 and pull it outward to disassemble the filter 104, so that the filter 104 can be easily removed and is convenient for users to clean. In this way, the filter 104 can be cleaned regularly to maintain the efficient operation of the dust collection mechanism and extend the service life of the filter 104.

[0028] When the staff needs to install the filter 104, they align one side of the filter 104 with the installation groove 2 and push it in to complete the installation of the filter 104. In the process of pushing the filter 104 in, the filter 104 may be offset, so that the bottom of the filter 104 cannot be stuck in the fixing groove 206. In order to avoid this situation, positioning grooves 405 are provided on both sides of the vacuum groove 204, and positioning blocks 406 are provided on both sides of the filter 104. The positioning blocks 406 are slidably connected to the inner wall of the positioning groove 405. The positioning grooves 405 and the positioning blocks 406 are provided to prevent the filter 104 from being offset or misplaced during the pushing process, thereby improving the accuracy of installing the filter 104 and the convenience of operation.

[0029] In this embodiment, the scraper assembly includes a pressure plate 4, a sliding plate 401, a scraper 402, and a plurality of elastic members 403. The elastic member 403 is a cylindrical compression spring, which can provide elastic supporting force. A scraper groove 404 is provided on the side of the top of the dust box 103 close to the dust pipe 102. The sliding plate 401 is slidingly connected to the inside of the scraper groove 404. The pressure plate 4 is arranged on the side of the sliding plate 401 away from the dust box 103 and is fixedly connected to the sliding plate 401. The pressure plate 4 and the sliding plate 401 can be integrally formed. The scraper 402 is arranged at one end of the sliding plate 401 inside the dust box 103 and is fixedly connected to the sliding plate 401, and the scraper 402 abuts against the surface of the filter 104. One end of each elastic member 403 is fixedly connected to the top of the dust box 103, and the other end of each elastic member 403 is fixedly connected to the pressure plate 4.

[0030] When the staff needs to remove the dust on the surface of the filter 104, they only need to move the pressing plate 4 downward to move the pressing plate 4 in the direction of compressing the elastic members 403. At the same time, the scraper 402 will scrape the dust or impurities on the surface of the filter 104 driven by the moving plate. Since the elastic member 403 has the force to restore the deformation, the staff can move the scraper 402 back and forth several times to improve the cleaning effect. At the same time, the scraper assembly in this embodiment has a simple structure and can reduce the manufacturing cost. The staff may tilt the moving plate during the pressing process, causing the scraper 402 to deviate. In order to avoid this situation, guide grooves 407 are provided on both sides of the scraper groove 404, and guide blocks 408 are provided on both sides of the sliding plate 401. The guide blocks 408 are connected to the inner wall of the guide groove 407 by sliding. The guide blocks 408 and the guide grooves 407 can prevent the moving plate from tilting or deviating when the staff presses down the moving plate, thereby improving the stability of the moving plate movement and improving the cleaning effect of the scraper 402.

[0031] In order to facilitate the handling of dust sucked into the dust box 103, a collecting box 3 is movably connected to the side of the dust box 103 close to the dust pipe 102, a slope 207 is provided on the side of the fixed block 205 close to the collecting box 3, and a second handle 301 is fixedly connected to the outer surface of the collecting box 3.

[0032] When the engraving machine is working, the negative pressure component 105 can be started to generate negative pressure inside the dust box 103. Under the action of air pressure, dust enters the dust box 103 through the dust suction pipe 102. The filter 104 provided can intercept the dust. When the engraving machine stops working, the dust will automatically fall into the collection box 3 under the influence of gravity, and the dust or impurities attached to the surface of the filter 104 can be scraped off by the scraper component, so that the dust or impurities fall into the collection box 3. The inclined surface 207 provided on the side of the fixed block 205 close to the collection box 3 can play a role in guiding the dust to fall into the collection box 3, which can prevent dust from accumulating on the fixed block 205, thereby improving the dust collection efficiency. The second handle 301 provided can facilitate the staff to pull out the collection box 3 and clean the dust inside.

[0033] Working principle: When the engraving machine is working, the negative pressure component 105 can be started to generate negative pressure inside the dust box 103. Under the action of air pressure, dust enters the dust box 103 through the dust pipe 102. The filter 104 can intercept dust to prevent it from entering the negative pressure component 105 and causing damage. The dust collection mechanism can timely remove dust and waste generated during the engraving machine processing, keep the working environment clean, and reduce the impact of dust on the equipment and operators. At the same time, the dust collection mechanism can prevent dust from accumulating on the tool or spindle, thereby improving the cutting ability of the tool and reducing the processing quality.

[0034] When the engraving machine stops working, the dust will automatically fall into the collection box 3 due to the influence of gravity. As for the dust or impurities attached to the surface of the filter 104, the staff can move the pressure plate 4 downward to make the pressure plate 4 move in the direction of compressing the elastic members 403. At the same time, the scraper 402 will scrape off the dust or impurities on the surface of the filter 104 driven by the moving plate. The inclined surface 207 can guide the dust into the collection box 3, thereby facilitating collection. When cleaning is completed, the collection box 3 can be pulled out through the second handle 301 to clean the dust inside.
