Description

A dust removal device for laser cutting machines Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust removal device applied to a laser cutting machine. Background Technology

[0002] Laser cutting utilizes a focused, high-power-density laser beam to irradiate the workpiece, causing the irradiated material to rapidly melt, vaporize, ablate, or reach its ignition point. Simultaneously, a high-speed airflow coaxial with the beam blows away the molten material, thus cutting the workpiece. However, laser cutting machines generate significant amounts of smoke, metal shavings, large particles of waste, sparks, and residual laser light during operation, posing considerable health risks to workers. Traditional dust removal equipment uses welded, fixed frame structures that lack strength, making products susceptible to deformation during transport. Furthermore, these systems are noisy and have poor filtration efficiency. Summary of the Invention
