Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a dust removal device for laser cutting machines. Background Art

[0002] The laser cutting machine is a machine that emits laser light from a laser and focuses it into a high-power density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. As the relative position of the beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting. When processing metal materials, a laser cutting machine is needed to process the shape of the material to be processed.

[0003] A laser cutting machine is needed when processing metal materials. The "a laser cutting machine dust removal device" disclosed in the publication number "CN205600133U" has solved the problem that when cutting the workpiece, the large-diameter scraps generated will be sucked into the dust suction port of the dust suction device. If this continues for a long time, the port will easily be blocked, which greatly reduces the dust suction effect of the dust suction device.

[0004] However, there are still many defects in the actual use of laser cutting machines with similar structures, such as: it does not have an anti-clogging function, and the residues generated by cutting materials using the device can easily clog the inside of the device, resulting in the operator needing to use external equipment to clear the inside of the device, which increases the operator's workload. At the same time, it does not have the function of automatically collecting dust and impurities collected inside the device, and the device needs to be disassembled to collect the dust and impurities accumulated inside the device, which reduces the automation effect of using the device. Therefore, it is necessary to design a dust removal device for a laser cutting machine. Utility Model Content
