Description

Technical Field

[0001] The utility model relates to the technical field of waste collection mechanisms, in particular to a laser cutting waste collection mechanism. Background Art

[0002] Laser cutting uses the energy released when the laser beam hits the surface of the workpiece to melt and evaporate the workpiece, so as to achieve the purpose of cutting and engraving. 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 hits 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 melted or vaporized metal. As the relative position of the beam and the workpiece moves, the material is eventually cut, thereby achieving the purpose of cutting.

[0003] In the process of laser cutting workpieces, a large amount of waste will be generated. If these wastes are not collected in time and effectively, they will pollute the working environment and may affect the normal operation of the equipment. The current waste collection method has the problem of low efficiency, so how to solve this problem is what we need to consider. Utility Model Content
