Description

Technical Field

[0001] The utility model relates to the technical field of cleaning racks of laser cutting machines, in particular to a cleaning device for racks of laser cutting machines. Background Art

[0002] Laser cutting machine is to focus 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, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal.

[0003] Laser cutting machines generally use a rack support plate to support the workpiece to be cut. When the workpiece is cut, corroded iron chips and residues often fall and adhere to the rack support plate. The rack support plate needs to be cleaned regularly. The cleaning method in the prior art is that workers clean the rack support plate by dropping the rack support plate or knocking it manually. This cleaning method will not only damage the rack support plate, but the fallen iron chips will also be inhaled by the workers and cause harm to people's health. This needs to be improved.
