Technical Field
[0001] The utility model relates to the technical field of dust collectors, in particular to a dust collector for a laser cutting machine. Background Art
[0002] Laser cutting machine is a device that uses high-energy-density laser beam to cut workpieces. Through the irradiation of laser beam, the local area of the workpiece surface is heated to a melted or vaporized state, thereby achieving the purpose of cutting. Laser cutting machine has the advantages of fast cutting speed, high precision, and wide application range. It is widely used in metal processing, plate processing and other fields. The current laser cutting machine will generate a lot of smoke and dust during operation. These smoke and dust will corrode the equipment and also cause harm to the health of the operator.
