It usually uses high-energy laser beams to cut various materials into desired shapes, including metals, plastics, wood, glass, etc. Laser cutting equipment can be widely used in many fields such as industrial production, manufacturing, construction, and art. The working principle of laser cutting equipment is to focus the laser beam to a very small focus, and use the thermal energy of the high-energy laser beam to heat and melt the material to achieve cutting. Laser cutting can generate extremely high energy density on the surface of the material, causing the material to melt and evaporate rapidly, thereby achieving high-precision, high-speed and high-quality cutting.

[0030] Reference Figure 1 - Figure 3The utility model provides an embodiment: a laser cutting device with smoke exhaust and dust removal function, comprising a protective shell 1, a laser cutting machine 2 is fixedly connected to the bottom of the protective shell 1, a motor 3 is fixedly connected to the right side of the rear of the protective shell 1, a threaded rod 4 is fixedly connected to the output end of the motor 3, a scraper 5 is threadedly connected to the outer side of the threaded rod 4, a sliding rod 6 is slidably connected to the left side of the scraper 5, a smoking port 8 is opened on the top of the protective shell 1, a processing box 7 is fixedly connected to the top of the protective shell 1, a smoke exhaust fan 9 is fixedly connected to the right side of the processing box 7, a filter assembly is installed inside the processing box 7, front and rear ends of the threaded rod 4 are rotatably connected to the inside of the protective shell 1, front and rear ends of the sliding rod 6 are fixedly connected to the inside of the protective shell 1, and the bottom of the scraper 5 is slidably connected to the inner bottom wall of the protective shell 1.
[0031] Specifically, the protective shell 1 is used to connect other parts to protect the laser cutting machine 2 from external factors affecting the cutting accuracy during cutting. The motor 3 is used to drive the threaded rod 4 to rotate. The threaded rod 4 is used to drive the scraper 5 to move back and forth. The scraper 5 is used to scrape the debris scattered on the bottom of the protective shell 1 and collect it on the front side of the protective shell 1 for unified processing. The slide bar 6 is used to limit the movement direction of the scraper 5 to ensure that the scraper 5 can only move back and forth and will not move around. The processing box 7 is used to centrally process the smoke. The smoking port 8 is used to facilitate the inhalation of smoke into the processing box 7. The smoke exhaust fan 9 is used to inhale the smoke into the processing box 7 and discharge it.
[0032] Reference Figure 2 - Figure 4 The filter assembly includes an inner frame 10, the outer wall of the inner frame 10 is slidably connected to the inner wall of the processing box 7, the inner frame 10 is slidably connected with a filter screen 11, the rear side of the inner frame 10 is fixedly connected to an outer shell 12, the inner shell 12 is fixedly connected to a partition 13, the left and right sides of the partition 13 are fixedly connected to a limit rod 14, the outer side of the limit rod 14 is slidably connected to a plug rod 15, the adjacent sides of the two plug rods 15 are fixedly connected to springs 16, the outer wall of the plug rod 15 is fixedly connected to a side close to the spring 16, the spring 16 is internally sleeved on the outside of the limit rod 14, the adjacent ends of the two springs 16 are fixedly connected to the left and right sides of the partition 13, the outer side of the paddle 17 is slidably connected to the inside of the outer shell 12, the outer wall of the plug rod 15 passes through the outer shell 12 and is inserted into the rear side of the protective shell 1, and the bottom of the inner frame 10 is slidably connected to the top of the protective shell 1.
[0033] Specifically, the inner frame 10 is used to install the filter 11. The smoke generated during the cutting process contains a large amount of harmful substances such as nitrogen oxides, carbon dioxide, carbon monoxide, hydrogen, metal vapor, etc. The filter 11 is used to filter the harmful substances contained in the smoke. The filter 11 is an activated carbon with a large number of micropores and mesoporous structures on the surface, which can adsorb a variety of metal ions on its surface. The outer shell 12 is used to protect and connect the internal parts. The partition 13 is used to fix the limit rod 14 and the spring 16.

The smoke generated during the cutting process is passed through the rotation of the smoke exhaust fan 9, and the smoke floats into the processing box 7 from the smoking port 8. The nitrogen oxides, carbon dioxide, carbon monoxide, hydrogen, metal vapor and other harmful substances contained in the smoke are adsorbed cleanly through the filter 11, and the filtered smoke is discharged into the air through the smoke exhaust fan 9. When the cutting is completed, the motor 3 is controlled to rotate by an external power supply, and the motor 3 drives the threaded rod 4 to rotate. At this time, the screw The scraper 5 on the pattern rod 4 moves forward under the limit of the slide rod 6, and pushes the debris to the front of the protective shell 1 for subsequent processing. Then, the handle on the rear side of the inner frame 10 is grasped, and by simultaneously shifting the two paddles 17, the rod 15 will move together toward the inside of the outer shell 12 to unlock, and the inner frame 10 is pulled out. Then the filter 11 is removed and replaced with a new filter 11, and the inner frame 10 is reinserted into the processing box 7. At this time, the paddle 17 is released, and the rod 15 will be reinserted into the rear side of the processing box 7 due to the thrust of the spring 16 to complete the fixation.
