Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a laser cutting machine capable of avoiding splashing of waste materials. 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] For example, a laser cutting machine that can automatically clean waste materials with application publication number "CN117884778A" is used. Then the laser cutting head is started to move forward to the cutting position. At the same time, the trigger plate drives the single-hole piston rod to move upward through the roller, and the water in the water inlet pipe is discharged into the guide pipe. The water in the guide pipe is slowly sprayed out through the nozzle and flows on the support frame to form a water flow layer. When the laser cutting head cuts the plate, the waste material falls and is removed by the water flow layer to prevent the waste material from adhering to the support frame and agglomerating to scratch the plate placed later, thereby ensuring the integrity of the plate. However, when the laser cutting machine that can automatically clean waste materials performs laser cutting processing on the workpiece, it is necessary to fix the position of the workpiece first, and then perform laser cutting processing on the workpiece. However, the device does not limit the position of the workpiece. When laser cutting is performed, the position of the workpiece will be offset, affecting the laser cutting work of the workpiece. At the same time, when the laser cutting machine that can automatically clean waste materials performs laser cutting work, waste materials will be generated. The waste materials cannot be directly collected, and the waste materials will splash around, affecting the surrounding working environment. Summary of the invention
