Description

Technical Field

[0001] This utility model relates to the field of laser machine technology, specifically to a smoke removal device for a laser machine. Background Technology

[0002] Laser machines are a general term encompassing laser engraving machines, laser cutting machines, and laser marking machines. They utilize their high-temperature working principle to act on the surface of the material being processed, simultaneously drawing patterns, text, and other designs required by the customer based on the graphics input into the machine.

[0003] A search revealed a smoke removal device for a laser machine, disclosed in patent application number CN201820090922.X. This device includes a hollow smoke extraction plate fixed to a gantry frame connecting to a laser head. The smoke extraction plate has a through hole for mates with the laser head. Smoke extraction ports are located on the bottom of the smoke extraction plate and the sidewalls of the through hole. The smoke extraction plate also has an exhaust vent communicating with the smoke extraction ports. This smoke removal device for a laser machine can more effectively remove smoke near the laser head, exhibiting high smoke removal efficiency, a reasonable and simple structure, and easy and convenient installation.

[0004] However, this patent still has shortcomings. The laser smoke removal device lacks components that can filter impurities, odors, and harmful gases in the smoke. Directly discharging the smoke outdoors during the smoke removal process can easily cause environmental pollution, and the smoke and dust directly entering the smoke extraction plate can easily cause blockage, affecting the subsequent smoke removal effect.

[0005] Therefore, we propose a smoke removal device for laser machines. Utility Model Content

[0022] Please see Figures 1 to 4 This utility model provides a smoke removal device for a laser machine, including a laser head 1 and a processing box 2. Two connecting plates 6 are fixedly installed on the right side of the processing box 2, and the two connecting plates 6 are fixedly installed on the laser head 1 by external bolts. A filter seat 3 is fixedly installed on the left side of the processing box 2. An adjusting seat 10 is rotatably connected inside the filter seat 3. A cover plate 12 is provided on the left side of the adjusting seat 10. A cross shaft 19 is rotatably connected on the right side of the cover plate 12. A cross slot 20 is provided inside the adjusting seat 10. The cross shaft 19 is inserted into the cross slot 20. Multiple filter chambers 13 are provided inside the adjusting seat 10 outside the cross slot 20. A connecting pipe 9 is fixedly installed on the right end of the cover plate 12. A smoke bucket 5 is fixedly installed at the bottom of the processing box 2. A connecting port 24 is provided on the left side of the processing box 2 corresponding to one of the filter chambers 13. A bracket 15 is inserted into the upper part of the connecting port 24 inside the processing box 2. An activated carbon filter element 14 is fixedly installed inside the bracket 15. Two exhaust fans 16 are fixedly installed at the top of the processing box 2.

[0023] A threaded tube 7 is fixedly installed on the left side of the smoking pipe 5. A threaded cover 8 is rotatably connected to the outer side of the connecting tube 9 away from the cover plate 12. The threaded cover 8 is threaded onto the outside of the threaded tube 7. This design facilitates the assembly and disassembly of the connecting tube 9 and the smoking pipe 5. Locking strips 21 are fixedly installed on the right sides of both the front and rear ends of the cover plate 12. Connecting seats 22 are provided at both the front and rear ends of the adjusting seat 10. Two locking strips 21 are respectively inserted into the corresponding connecting seats 22. This design facilitates the assembly and disassembly of the cover plate 12. Locking bolts 23 are threadedly connected to the outer side of each connecting seat 22 away from each other. The inner end of each locking bolt 23 extends into the locking strip 21. The locking bolt 23 can limit and fix the clip 21. The front end of the insert 15 is fixedly installed with a lever 17. The lever 17 is internally threaded with a fixing bolt 18. The rear end of the fixing bolt 18 extends into the processing box 2. The fixing bolt 18 can limit and fix the lever 17. The front end of the processing box 2 is located below the lever 17 and is fixedly installed with a PLC controller 4. The PLC controller 4 facilitates the control of the equipment. The left side of the cover plate 12 is fixedly installed with a motor 11. The output end of the motor 11 is fixedly installed on the cross shaft 19. The motor 11 drives the cross shaft 19 to rotate, which is beneficial to the use of the equipment.

[0024] Working principle: Multiple filter chambers 13 are fixedly equipped with filter screens. During use, when the laser head 1 generates smoke and dust during laser engraving, the two exhaust fans 16 work to exhaust the air in the processing box 2. At this time, a negative pressure is generated at the smoke bucket 5 to draw in the smoke and dust. When the smoke and dust enter the filter chamber 13 through the connecting pipe 9, the smoke and dust particles in the smoke are filtered and accumulated in the filter chamber 13. Then, the smoke enters the processing box 2 through the connecting port 24, and then passes through the activated carbon filter element 14 to adsorb and purify harmful substances and odors before being discharged. The PLC controller 4 will periodically start the motor 11. Each time, the motor 11 drives the cross shaft 19 to rotate 90 degrees, and the cross shaft 19 drives the adjusting seat 10 to rotate 90 degrees, which can rotate the unused filter chamber 13 into the connecting pipe 9, avoiding excessive accumulation of smoke and dust impurities in the filter chamber 13 to clog the filter screen and affect the smoke extraction efficiency. When cleaning is required, first unscrew the two locking bolts 23, then unscrew the threaded cover 8 to disconnect the threaded cover 8 from the threaded tube 7. Then pull the cover plate 12 to the left to disengage the two locking strips 21 from the connecting seat 22, and then remove the cross shaft 19 from the cover plate 12. Then remove the adjusting seat 10 to clean the smoke and dust impurities in the multiple filter chambers 13. This type of laser machine smoke removal device is easy to use. Through the above components, it can filter and adsorb impurities, odors and harmful gases in the smoke before emission, thereby avoiding the problem of direct emission of smoke and dust that easily pollutes the environment. At the same time, it can automatically switch the filter chamber 13 periodically for the use of smoke and dust impurity filtration, avoiding smoke and dust impurities clogging the filter screen and affecting the smoke removal efficiency of this equipment. It can also quickly disassemble and assemble the adjusting seat 10 and the filter seat 3 to facilitate the cleaning of the filtered smoke and dust impurities.
