[0002] In the production and manufacturing process of advertising materials, such as metal brackets, acrylic boards, light box boards, KT boards, etc., it is often necessary to cut the above materials. At present, efficient laser cutting machines are generally used. Laser cutting machines use the principle of laser melting materials to cut materials. The gantry drives the laser head to move in the X, Y, and Z axis directions to achieve precise cutting of materials.

[0003] During the cutting process, the melting of materials will produce a certain amount of smoke and dust. Some plastic materials will produce toxic gases after melting, which will not only affect the workshop environment, but more importantly, will harm the health of the staff. At present, workshops generally use large-scale integrated dust removal equipment, which is collected uniformly by multiple dust removal fans installed at high places in the workshop, and then transported to the purification equipment installed outside the workshop through a central pipeline for centralized treatment. However, this type of dust removal equipment is expensive, complicated to arrange, and cannot perform dust removal operations on a single device. Therefore, the use effect is average and needs to be improved. Utility Model Content
