[0002] Laser cutting machine is an advanced manufacturing technology equipment, which uses high energy density laser beam as cutting means, and realizes efficient, precise and automatic cutting of various materials (including metal and non-metal) by precisely controlling the path and intensity of laser beam. The smoke and dust generated during laser cutting are captured by the dust hood and transported to the dust removal equipment through the pipeline. Inside the dust removal equipment, when the smoke and dust pass through the filter element (or filter cartridge), the particles are intercepted, and the purified air is discharged through the fan.

However, when performing large-scale cutting processing, the cutting mechanism moves a long distance in a short time, resulting in the dust removal mechanism being unable to perform dust removal processing efficiently.

This structure enables the first dust hood 7 to draw air through the dust suction branch pipe 9, allowing the extracted smoke to enter the dust suction pipe 12, and then pass through the dust suction pipe 12 into the dust collecting box 16 for smoke purification. The second dust hood 10 is sealed and connected with the dust suction pipe 12 on the side. The dust suction branch pipe 9 is a Y-shaped pipe, and the dust suction branch pipe 9 is inserted in the dust suction pipe 12, so that the dust suction branch pipe 9 and the dust suction pipe 12 can generate negative pressure suction force through the same fan, thereby increasing the dust collection range. A support frame 3 is provided under the second dust hood 10, and a workbench 6 is provided on the laser cutting machine body 1, and guide rails 5 are symmetrically fixed on both sides of the long side of the workbench 6, and the guide rails 5 are connected to the support frame 3. The lower ends of the support frames 3 are movably connected, and this structure enables the support frame 3 to be moved under the guidance of the guide rail 5. A connecting plate 4 is fixed between the support frame 3 and the door-type moving frame 2 by bolts, and a pneumatic telescopic rod 15 is symmetrically arranged between the support frame 3 and the second dust hood 10. This structure allows the support frame 3 to be fixed relative to the door-type moving frame 2 through the connecting plate 4, so that the door-type moving frame 2 drives the support frame 3 to move, thereby realizing the movement of the second dust hood 10. The second dust hood 10 is used to assist in dust extraction, expand the dust extraction range, and avoid the situation where dust extraction is not timely. The pneumatic telescopic rod 15 is tilted, and the two ends of the pneumatic telescopic rod 15 are connected to the support frame 3 by a rotating rod structure.

[0020] Working principle: When using the laser cutting machine with a mobile dust removal mechanism, first, the laser cutting machine body 1 drives the laser cutting head 8 to move through the door-type moving frame 2, the first dust hood 7 moves synchronously with the laser cutting head 8, and the second dust hood 10 moves synchronously with the door-type moving frame 2, so that the second dust hood 10 is fixed by the connecting piece 14 and rotated relative to the support frame 3 by adjusting the rotating shaft 13, and the opening angle of the second dust hood 10 can be adjusted. The pneumatic telescopic rod 15 plays a role in adjusting and stabilizing the second dust hood 10, and the connecting plate 4 is connected to the door-type moving frame 2 and the support frame 3. The guide rail 5 is used to assist the movement of the support frame 3, so that the laser cutting head 8 can perform laser cutting on the workpiece on the workbench 6. The smoke generated by the cutting is sucked by the fan in the dust removal box 16 to generate negative pressure suction, and the suction force is generated through the dust suction pipe 12 and the dust suction branch pipe 9 to extract the smoke from the first dust hood 7 and the second dust hood 10. The dust removal is performed by the dust removal box 16. The buckle 11 has a role in stabilizing the connection between the dust suction branch pipe 9 and the dust suction pipe 12.
