Detailed Description of the Embodiment

[0018] The following further describes the present application in detail Figures 1-5 in conjunction with the attached drawings.

[0019] The embodiment of the present application discloses a fume treatment mechanism for a laser cutting machine, including a frame 1, on which a cover body 2 and an air extraction mechanism are arranged. The bottom surface of the cover body 2 is closed, and uniformly distributed air inlets 6 are provided on the side surface of the cover body 2. A trough 11 is provided on the bottom surface of the cover body 2, and a detachable dust collection tray 5 is arranged at the bottom of the cover body 2, and dust accumulates in the dust collection tray 5 through the trough 11.

[0020] Furthermore, the air extraction mechanism includes a pump 4 fixedly installed on the top of the frame 1, and the pump 4 is connected to the cover body 2 through a pipeline 3.

[0021] In this embodiment, during the laser cutting process, when the pump 4 is turned on, the fumes generated by the laser cutting can be sucked into the cover body 2 through the air inlet 6 and then discharged through the pipeline 3. Since the air inlet 6 is provided on the side surface of the cover body 2 and the dust collection tray 5 is arranged at the bottom of the cover body 2, part of the dust settles in the cover body 2 and falls into the dust collection tray 5 through the trough 11, collecting the dust.

[0022] Further, a plurality of connecting plates 7 are provided on the cover body 2. There are at least three groups of connecting plates 7, and the three groups of connecting plates 7 are distributed in an annular array on the lower surface of the cover body 2. Slots 9 are formed on the surfaces of the connecting plates 7. Blocks 8 corresponding to the connecting plates 7 one by one are fixedly connected to the surface of the dust collecting tray 5. Both the slots 9 and the blocks 8 are arc-shaped, and the blocks 8 can be rotated into the inside of the slots 9.

[0023] In this embodiment, by setting the cooperation of the blocks 8 and the slots 9, when it is necessary to remove the dust collecting tray 5, only need to rotate the dust collecting tray 5 to move the blocks 8 on the dust collecting tray 5 out of the slots 9 on the connecting plates 7, and then pour out the dust accumulated in the dust collecting tray 5, and the dust collecting tray 5 can be cleaned; when it is necessary to reinstall the dust collecting tray 5, only need to screw the blocks 8 back into the slots 9.
