[0002] At present, the first step in stainless steel plate processing is to cut the incoming material according to size, and laser cutting technology is mostly used for cutting. Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to quickly melt, vaporize, ablate or reach the ignition point, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the workpiece. Laser cutting is one of the thermal cutting methods.
[0003] Laser cutting produces a lot of harmful gases and particles during operation, including nitrogen oxides, photochemical ozone, organic matter, etc., which are harmful to human health. These harmful gases not only pollute the environment, but also harm the operator of the laser cutting machine. Therefore, the exhaust system is crucial to the operation of the laser cutting machine and environmental protection. Utility Model Content
