Description

A dust removal mechanism for magnetic material laser cutting machine

Technical Field

The utility model relates to the technical field of laser cutting machines, in particular to a dust removal mechanism for a magnetic material laser cutting machine.

Background Art

Laser cutting machine is to focus 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. As the relative position of the beam and the workpiece moves, the material is eventually cut, thereby achieving the purpose of cutting. Nowadays, laser cutting machines are usually used for cutting magnetic materials. When using a laser cutting machine to cut magnetic materials, a large amount of smoke and toxic gases will be generated, so the smoke treatment of laser cutting is particularly important.

After searching, the Chinese utility model patent with authorization announcement number "CN217991334U" discloses a magnetic material laser cutting machine with stable cutting performance. The application proposes the prior art problem that "when cutting magnetic materials, the dust and fume generated by the cutting, in addition to harmful gases, also contain some powdered magnetic materials. These powdered magnetic materials will cause the suction fan to be blocked. If a filter is set at the front end of the suction fan alone, the accumulation of powdered materials will easily lead to blockage of the filter, and the filter needs to be manually unblocked regularly afterwards." In response to this problem, the applicant proposed a dust removal mechanism for a magnetic material laser cutting machine to solve the problem that when a filter is used in the prior art to intercept and filter powdered materials, the filter needs to be manually unblocked regularly.
