Description

Technical Field

[0001] The utility model relates to dust removal equipment, in particular to dust removal equipment used for a laser cutting machine, and belongs to the technical field of laser cutting machines. 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.

[0003] However, the existing laser cutting machines lack dust removal measures, and waste chips will be generated during the cutting process of materials. Since the laser beam irradiates the surface of the material and cuts it quickly, waste materials may splash and cause physical harm to surrounding workers, posing a safety hazard. Secondly, the waste chips accumulated on the surface of the workbench will also affect the next cutting effect.

[0004] To this end, a dust removal device for a laser cutting machine is proposed. Utility Model Content
