Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a laser cutting head self-cleaning device and a laser cutting machine. Background Art

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. After the cutting nozzle of the laser cutting machine has been cutting for a long time, due to spattering, the surface of the nozzle closest to the cutting point is very likely to be adhered to metal particles, affecting the normal flow direction of the cutting gas flow, and increasing the error value of the capacitive sensor, thereby affecting the gap value between the nozzle and the plate, and the cutting quality deteriorates. The existing announcement number is CN 220160626 U, which is a self-cleaning device for a laser cutting head for a laser cutting machine. The device drives a brush plate to make a circular motion at the lower end of the cutting head by rotating a motor, so that the cleaning sponge on the upper end of the horizontal plate cleans the lower end of the cutting head, and the cleaning sponge on the side end of the vertical plate cleans the side end surface of the cutting head, thereby realizing the cleaning of the cutting head by the cleaning sponge, thereby making the nozzle surface at the lower end of the cutting head clean; however, the above-mentioned device needs to adjust the position of the motor through two hydraulic telescopic rods, and the motor drives the brush plate to rotate and then clean the cutting head. The overall movement power is relatively large, which increases the use cost of the device. Utility Model Content
