Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and specifically to a laser cutting mechanism. Background Technology

[0002] Laser cutting is a technology that uses a high-power-density laser beam to irradiate a material, rapidly heating it to its vaporization temperature, causing it to evaporate and form a hole. The material is then cut by moving the laser beam. This technology can be used to cut various materials, including metals (such as stainless steel, carbon steel, and aluminum) and non-metals (such as plastics, wood, fabrics, and paper).

[0003] Laser cutting generates smoke, which is mainly composed of tiny particles and gases formed by the evaporation or combustion of materials after being heated. Different materials produce smoke with different compositions during laser cutting. For example, metals, plastics, and wood release their own specific chemical substances during cutting. This smoke may contain harmful substances, and if the smoke diffuses into the production workshop, it can easily pose a threat to the health of the operators. Utility Model Content
