Description

Technical Field

[0001] This utility model relates to the field of carbon dioxide laser cutting technology, specifically a dustproof device for the cutting head of a carbon dioxide laser cutting machine. Background Technology

[0002] Laser cutting technology is a technique that uses a high-power-density laser beam to irradiate the material being cut, causing the material to melt, vaporize, ablate, or reach its ignition point rapidly. At the same time, a high-speed airflow coaxial with the laser beam blows away the molten material, thereby cutting the workpiece. In current industrial production, CO2 laser cutting machines are favored due to their high precision, high efficiency, and wide range of applications.

[0003] However, metal powder, dust, and other impurities generated during the cutting process easily adhere to the cutting head, affecting not only the cutting quality but also potentially damaging the cutting head, increasing maintenance costs and downtime. Existing dust prevention measures mostly rely on external protective covers or regular manual cleaning, which have limited protective effects and are cumbersome to maintain. Utility Model Content
