Description

A dust removal mechanism for laser cutting machine

Technical Field

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

Background Art

When cutting metal and other materials, laser cutting machines will generate a large amount of metal debris and harmful gases, which will be harmful to the human body. Therefore, when using laser cutting machines, they need to be dusted. The most common method is to use a cartridge dust collector. The dust generated by laser cutting is collected through the pipes on the cartridge dust collector, so that the cutting dust will not spread to the workshop, which not only ensures the cleanliness of the working parts, but also reduces the risk of contamination of the machine's precision parts and ensures the health of workers. This method has high dust removal efficiency and the workshop conditions meet environmental assessment standards.

At present, when the filter cartridge dust collector in the prior art removes harmful substances caused by the laser cutting machine, it will also absorb the larger metal particles generated during laser cutting onto the filter net. However, the larger metal particles will cause the mesh of the filter net to be blocked, and the filter net needs to be cleaned and replaced regularly, resulting in reduced dust removal effect and higher use cost, and poor use effect.

Therefore, in view of the above problems, a dust removal mechanism for a laser cutting machine is proposed.

The dust collecting net 3 is cleaned by driving the connecting ring 12 and the cleaning frame 13 to rotate by the cleaning motor 19, and the transmission speed is uniform and uniform, and the rotation speed can be adjusted to improve the cleaning effect of the dust collecting net 3, thereby further improving the use effect of the device. When the dust collecting frame 2 and the dust collecting net 3 need to be replaced, the dust collecting frame 2 and the dust collecting net 3 are released by installing the bolts 11, and then the dust collecting frame 2 is pulled outward. In the process of pulling the dust collecting frame 2, the telescopic spring 20 is squeezed by the limiting steel ball 21, and then the limiting steel ball 21 is squeezed into the replacement groove, and then the limiting of the dust collecting frame 2 is released, and the dust collecting frame 2 and the dust collecting net 3 are taken out from the dust collecting pipe 1 and replaced.
