Laser engraving machine

Abstract

The invention belongs to the field of engraving, and particularly relates to a laser engraving machine. The laser engraving machine comprises a laser engraving machine body, a smoke exhaust pipe is connected to one side of the outer side wall of the laser engraving machine body, a machine cover is connected to the upper surface of the laser engraving machine body, a water tank is connected to oneside of the rear surface of the laser engraving machine body, and a dust prevention mechanism is arranged behind the inner side wall of the laser engraving machine body. Through the arrangement of a dust prevention plate, a rotating wheel and a blowing fan, dust in the external environment is not prone to entering the laser engraving machine, moreover, dust attached to the surface of a workpiece is removed, and the problems that the engraved workpiece is deviated in shape and the surface is rough and not attractive cannot be caused; an electric push rod, a support and bristles are arranged, the bristles clean the inner wall of the water tank, and then the situation that due to the fact that moss grows on the inner wall of the water tank, the water cooling effect is affected, and normal operation of the laser engraving machine is affected is prevented; and through the arrangement of an activated carbon plate and a filter box, exhausted gas cannot pollute the environment.

Description

technical field [0001] The invention relates to the field of engraving, in particular to a laser engraving machine. Background technique [0002] Laser engraving machine, as the name suggests, is an advanced equipment that uses laser to engrave the material that needs to be engraved. The laser engraving machine can improve the engraving efficiency, make the surface of the engraved place smooth and round, rapidly reduce the temperature of the engraved non-metallic material, and reduce the deformation and internal stress of the engraved object. [0003] There are following problems in prior art: [0004] 1. During the engraving process of the workpiece to be processed by the laser engraving machine, the dust in the external environment is easy to contaminate the surface of the workpiece, making it difficult for the laser to directly act on the surface of the workpiece during engraving, resulting in deviations in the shape of the engraved workpiece, and the surface is rough N...

AI Technical Summary

Problems solved by technology

[0004] 1. During the engraving process of the workpiece to be processed by the laser engraving machine, the dust in the external environment is easy to contaminate the surface of the workpiece, making it difficult for the laser to directly act on the surface of the workpiece during engraving, resulting in deviations in the shape of the engraved workpiece, and the surface is rough unsightly

[0005] 2. In the process of engraving the workpiece to be processed, the laser engraving machine needs to use the water flow in the water tank to cool each device. During the long-term storage of the water flow, the inner wall of the water tank is prone to moss due to impurities in the water flow. The moss is easy to grow after falling off. Cause the blockage of the water pipe, affect the water cooling effect and the normal operation of the laser engraving machine

[0006] 3. When the laser engraving machine is engraving the workpiece to be processed, the smoke generated by engraving is directly discharged from the exhaust pipe to the external environment, which is easy to cause environmental pollution
