Technical Field
[0001] This utility model relates to the field of steel structures, and in particular to a dust removal mechanism for a laser cutting machine with a steel structure. Background Technology
[0002] A search of Chinese patents revealed CN220498092U, a dust removal mechanism for a laser cutting machine, comprising a main body and a dust removal unit. This utility model provides a dust removal mechanism for a laser cutting machine. When the machine starts normally, gas containing a large amount of laser cutting fumes enters the dust removal mechanism through the suction port. Large dust particles and dust-laden sparks are extinguished by layers of filters and fall directly into the dust collection box. Very small amounts of fine dust are filtered and deposited on the outer surface of the filter. Over time, the dust accumulates on the filter surface, reducing its permeability. Adjusting the fan speed cleans the dust adhering to the filter, reducing resistance and restoring suction. When the filter becomes clogged again, a cyclical cleaning process is performed. The funnel-shaped dust collection unit prevents dust from being stirred up again.
[0003] Existing dust removal mechanisms are inconvenient to maintain. Generally, the filters are installed inside the dust collection box, requiring regular maintenance of both the filter and the box. Maintenance necessitates opening the dust collection box cover, which is bolted in place and requires tools for disassembly and reassembly. This process is cumbersome, increasing workload and reducing efficiency. Furthermore, the position of the dust hood is fixed; if the cutting area is outside the hood, dust removal becomes difficult. Moving the hood requires disassembly, repositioning, and reinstallation, which is extremely troublesome, reducing practicality and usability. To address these issues, we propose a steel-structured dust removal mechanism for laser cutting machines. Utility Model Content

A disassembly and assembly mechanism 19 is provided at the bottom of the slider 17, and a dust suction hood 20 is provided at the bottom of the disassembly and assembly mechanism 19. A telescopic tube 21 connects the dust suction hood 20 and the processing box 2. By rotating the turntable 27, the screw 18 is rotated, which drives the slider 17 to move. The movement of the slider 17 moves the dust suction hood 20, thereby achieving the purpose of adjusting the position of the dust suction hood 20, reducing the workload, and improving practicality and applicability.
[0038] refer to Figure 5 The disassembly and assembly mechanism 19 includes a mounting base 22, the top of which is bolted to the bottom of the slider 17, and the inner wall of the mounting base 22 is slidably sleeved with the dust cover 20. A fixing pin 23 is provided through the dust cover 20 and the inner wall of the mounting base 22. A locking block 24 is slidably sleeved on the inner wall of the fixing pin 23. A second spring 25 is provided between the locking blocks 24. By setting up the disassembly and assembly mechanism 19, pressing the locking block 24 causes the locking block 24 to disengage from the mounting base 22, the fixing pin 23 is removed, and the dust cover 20 is removed, which facilitates the disassembly and assembly of the dust cover 20 and facilitates the maintenance of the dust cover 20.
[0039] refer to Figure 1 and Figure 2 The guide rod 26 is slidably sleeved on the inner wall of the fixing frame 1, and the bottom of the guide rod 26 is bolted to the top of the crossbar 15. By setting the guide rod 26, the stability of the crossbar 15 is improved.

[0041] Brief description of usage: Hold the pull plate 12 with both hands to move it. The movement of the pull plate 12 moves the pull rod 13, which in turn moves the locking rod 8, disengaging it from the locking hole 10. Remove the cover plate 7 for maintenance. After maintenance, replace the cover plate 7. The locking rod 8, under the action of the first spring 9, engages with the locking hole 10 to secure it, thus completing the maintenance and facilitating the process. Rotate the turntable 27. The rotation of the turntable 27 drives the screw 18 to rotate, which in turn moves the slider 17, which in turn moves the dust cover 20. Move the dust cover 20 to the desired position to adjust its position.
