[0001] The utility model belongs to the technical field of laser cutting, in particular to a laser cutting dust removal device. Background Art

[0002] Laser cutting uses a high-density laser beam to irradiate the material to heat it to the vaporization temperature to form holes. When the light moves on the surface of the material, the holes are connected into lines to form slits to complete the cutting of the material. When the laser cuts the material, a lot of smoke and dust will be generated, and a dust removal device is required.

[0003] When existing laser cutting dust removal devices are performing dust removal, a dust suction fan is usually placed above the cutting machine and then the dust suction point is connected through a pipe to transport the smoke to the outside, so as to reduce the large amount of smoke generated during cutting. During long-term use observation, it was found that when existing laser cutting dust removal devices are performing dust removal, the dust suction fan is usually installed above the cutting machine, which has the problem of being far away from the cutting position, causing the smoke to drift from the cutting position to the surrounding area.

[0004] To this end, the utility model provides a laser cutting dust removal device. Utility Model Content

When the cutter 17 contacts the material, the motor 12 is started to drive the lead screw 13 to rotate to move the first slider 14. At this time, the cutter 17 can be driven to move on the surface of the material to complete the cutting. At the same time, the vacuum pump 113 is started to drive the air flow from the end of the hose 112 into the connecting assembly and then discharged from the vacuum pump 113. The end of the hose 112 can move at the same time as the cutter 17 moves. At this time, the end of the hose 112 is close to the cutting position to suck away the smoke generated during cutting. In this step, the fixed block 16 is set to connect the end of the hose 112, which can move at the same time as the cutter 17 when the cutter 17 is cutting. The vacuum pump 113 cooperates with the hose 112 to suck air, so that the hose 112 is always close to the cutting position to suck away the smoke generated, so as to reduce the situation where the smoke is far away from the cutting position and drifts around.

[0025] like Figure 2 As shown, the side wall of the cutter 17 is fixedly connected to an air intake pipe 2; a plurality of air intake holes 21 are provided at the bottom of the air intake pipe 2; an air guide pipe 22 is connected to the top of the air intake hole 21; the air guide pipe 22 is connected to the hose 112; during operation, when the fixed block 16 moves, the air intake pipe 2 can be driven to move at the same time. At this time, the air intake pipe 2 is connected to the hose 112 through the air guide pipe 22. When inhaling, the air flow can enter the air intake pipe 2 from the air intake hole 21, and then enter the hose 112 through the air guide pipe 22, and then be discharged from the vacuum pump 113. In this step, the air guide pipe 22 is provided to connect the hose 112 and the air intake pipe 2, so that the air flow can flow from the air intake hole 21 into the air intake pipe 2 and the air guide pipe 22 and then into the hose 112 during inhalation, so as to increase the air suction range of the hose 112 and reduce the smoke and dust from drifting around.

[0026] like Figure 3As shown, the connection assembly includes a filter box 3; the filter box 3 is fixedly connected to the top of the operating table 1; the inner wall of the filter box 3 is fixedly connected with a filter screen 31; during operation, when the hose 112 sucks in the smoke and dust, it will enter the filter box 3. When the airflow flows to the vacuum pump 113, it will pass through the filter screen 31. At this time, the filter screen 31 can filter the airflow mixed with smoke and dust, and filter out the larger particles of smoke and dust. In this step, the filter screen 31 is set to filter the airflow mixed with dust, and filter out the larger particles of smoke and dust, so as to reduce the situation where the vacuum pump 113 is blocked by the larger smoke and dust particles.

[0027] like Figure 3 As shown, the side wall of the filter box 3 is provided with a slot 4; the side wall of the slot 4 is bolted with a cover plate 41; the slot 4 and the cover plate 41 are bolted together; a second electric push rod 42 is fixedly connected to the top of the operating table 1; a scraper 43 is fixedly connected to the end of the second electric push rod 42; during operation, when the filter 31 needs to be cleaned, the cover plate 41 is opened, and then the second electric push rod 42 is started to drive the scraper 43 to move toward the slot 4. At this time, the scraper 43 can scrape the surface of the filter 31, and push the smoke and dust particles remaining on the surface of the filter 31 from the slot 4, and then reset the cover 41. In this step, the second electric push rod 42 is set to push the scraper 43 to push the smoke and dust particles remaining on the surface of the filter 31 from the slot 4, so as to reduce the situation where smoke and dust particles remain on the surface of the filter 31 and cause blockage.

[0028] like Figure 3 As shown, the side wall of the filter box 3 is fixedly connected to a collecting box 5; a pull-out box 51 is placed in the collecting box 5; the collecting box 5 and the pull-out box 51 are in sliding cooperation; during operation, when the scraper 43 pushes the smoke particles remaining on the surface of the filter 31 out from the slot 4, they will fall into the pull-out box 51 below, and the pull-out box 51 can collect the smoke particles at this time. When the collection is completed, the pull-out box 51 is pulled out to pour out the smoke particles and then the pull-out box 51 is put back. In this step, the smoke particles pushed out from the slot 4 can be collected by setting the collecting box 5 and the pull-out box 51. The pull-out box 51 can be extracted and put back to facilitate the processing of the collected smoke particles to improve the convenience of collection.

[0029] like Figure 3 As shown, dust-absorbing cotton 6 is placed inside the filter box 3; the dust-absorbing cotton 6 is located at the bottom of the filter box 3; during operation, after the airflow is filtered by the filter screen 31, it will continue to flow to the vacuum pump 113. At this time, the airflow will pass through the dust-absorbing cotton 6 and then enter the vacuum pump 113. The dust-absorbing cotton 6 can filter the airflow again and absorb smaller smoke particles mixed in the airflow. In this step, the dust-absorbing cotton 6 can absorb smaller smoke particles when the airflow passes through, and then flow to the vacuum pump 113 to reduce the smoke particles entering the vacuum pump 113 and causing blockage.

[0030] like Figure 4 As shown, the side wall of the slot 4 is fixedly connected with a sealing ring 7; during operation, when the cover plate 41 is installed in the slot 4, the sealing ring 7 connects the slot 4 and the surface of the cover plate 41 to increase air tightness. In this step, the sealing ring 7 is arranged between the slot 4 and the cover plate 41 to increase air tightness and reduce the outflow of smoke and dust from the gap between the slot 4 and the cover plate 41.

[0031] Working principle: When working, the first electric push rod 15 is started to drive the fixed block 16 and the cutter 17 to move toward the material to be cut below when cutting. When the cutter 17 contacts the material, the motor 12 is started to drive the lead screw 13 to rotate to move the first slider 14. At this time, the cutter 17 can be driven to move on the surface of the material to complete the cutting. At the same time, the vacuum pump 113 is started to drive the air flow from the end of the hose 112 into the connecting assembly and then discharged from the vacuum pump 113. The end of the hose 112 can move with the cutter 17 At the same time, the end of the hose 112 is moved close to the cutting position to absorb the smoke generated during cutting. When the fixed block 16 moves, the air intake pipe 2 can be driven to move at the same time. At this time, the air intake pipe 2 is connected to the hose 112 through the air guide pipe 22. When suction is performed, the air flow can enter the air intake pipe 2 from the air intake hole 21, then pass through the air guide pipe 22, enter the hose 112, and then be discharged from the vacuum pump 113. When the hose 112 sucks the smoke, it will enter the filter box 3. When the air flow flows to the vacuum pump 113, it will pass through the filter screen. 31, at this time, the filter 31 can filter the airflow mixed with smoke and dust, and filter out the smoke and dust with larger particles. When the filter 31 needs to be cleaned, the cover 41 is opened, and then the second electric push rod 42 is started to drive the scraper 43 to move toward the slot 4. At this time, the scraper 43 can scrape the surface of the filter 31, and push the smoke and dust particles remaining on the surface of the filter 31 out of the slot 4, and then reset the cover 41. When the scraper 43 pushes the smoke and dust particles remaining on the surface of the filter 31 out of the slot 4, they will fall into the pull-out box below 51, at this time, the pull-out box 51 can collect the smoke particles. When the collection is completed, the pull-out box 51 is pulled out to pour out the smoke particles and then the pull-out box 51 is put back. When the airflow is filtered by the filter 31, it will continue to flow to the vacuum pump 113. At this time, the airflow will pass through the dust-absorbing cotton 6 and then enter the vacuum pump 113. The dust-absorbing cotton 6 can filter the airflow again and absorb the smaller smoke particles mixed in the airflow. When the cover plate 41 is installed in the slot 4, the sealing ring 7 connects the slot 4 and the surface of the cover plate 41 to increase the air tightness.
