Description

Dust absorption device for laser cutting machine processing

Technical Field

The utility model relates to the technical field of laser cutting machine dust removal, in particular to a dust adsorption device for laser cutting machine processing.

Background technique

Laser cutting machines are widely used in cutting various materials. Laser cutting uses a high-power density laser beam to scan the surface of the material, melt or vaporize the material in a very short time, and then blow the molten or vaporized material away from the cut to achieve the cutting of the material. Existing laser cutting machines can automatically complete the cutting of materials under the control of computer program commands, with high cutting efficiency. However, some materials generate a lot of dust and debris during laser cutting, which needs to be collected by a dust adsorption device.

The patent with announcement number CN211759269U discloses a laser cutting machine with a protective device, which relates to the field of laser cutting machine protection technology. In order to solve the problem that there is a lack of corresponding protective devices, the debris generated by processing is prone to sputtering, the edges of the debris are relatively sharp, which poses a safety hazard, and it is easy to absorb dust under the action of static electricity. The accumulation of a large amount of dust easily leads to reduced cutting accuracy, affecting use, and cannot meet the use requirements. A mobile frame is arranged above the cutting table, a cutting mechanism is arranged outside the mobile frame, a blower is arranged above the cutting mechanism, a laser cutting head is arranged below the cutting mechanism, a grid carrier is arranged below the laser cutting head, a filter bin is arranged below the grid carrier, a slag discharge port is arranged on one side of the filter bin, an exhaust fan is arranged inside the cutting table, air ducts are arranged on both sides of the exhaust fan, and glass protective covers are arranged on both sides of the cutting mechanism.

During use, the above-mentioned laser cutting machine uses a fan and a filter plate to suck and filter dust or debris, thereby cleaning the dust or debris. However, this cleaning method has a relatively poor cleaning effect, and the surface temperature of the workpiece is high after laser cutting, and it needs to be left to cool, which reduces work efficiency.
