Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a slag cleaning device and laser cutting equipment. Background Art

[0002] Laser cutting uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporated to form holes. As the beam moves over the material, the holes continuously form a very narrow (such as about 0.1mm) slit to complete the cutting of the material. When cutting metal sheets, laser cutting equipment in the prior art will leave a large amount of metal slag on the surface of the workbench. The metal slag accumulates and forms plates, which are difficult to clean, affecting the cutting of the finished product. Eventually, the entire workbench needs to be replaced, and the cutting cost is high. Utility Model Content

[0032] When the slag cleaning device 10 in the above embodiment is used, first, the workpiece to be cut is placed on the workbench 200. Secondly, the driving mechanism 300 drives the first rotating shaft 210 to rotate, and the first rotating shaft 210 drives the first rotating disc 220 to rotate, so as to transport the workpiece to be cut to the cutting position. Then, the laser cutting device cuts the workpiece to be cut, and slag will remain on the surface of the first rotating disc 220 during the cutting process. Finally, when the workpiece to be cut is cut, the driving mechanism 300 continues to drive the first rotating shaft 210 to rotate, and the first rotating shaft 210 drives the first rotating disc 220 to rotate, so as to unload the workpiece to be cut, and the first rotating disc 220 will also drive the slag to the first slag cleaning groove 410, so that the first slag cleaning member 400 can automatically and timely scrape off the slag on the first rotating disc 220, and no slag will accumulate on the first rotating disc 220, which ensures the cutting quality of the workpiece to be processed and prolongs the service life of the workbench 200. In addition, the first slag cleaning member 400 and the fixing seat 100 are detachable, which facilitates the maintenance and replacement of the first slag cleaning member 400 and improves the practicality of the slag cleaning device 10 .

[0043] As shown in FIG. 1 and FIG. 4 , in one embodiment, the driving mechanism 300 includes a driving member 310, a first transmission member 320 and a second transmission member 330. The number of the first transmission members 320 is the same as the number of the first rotating shafts 210. Each first transmission member 320 is correspondingly mounted on each first rotating shaft 210. There is at least one second transmission member 330. The outer side walls of two adjacent first transmission members 320 are sleeved with a second transmission member 330. The driving member 310 is in transmission connection with one of all the first transmission members 320, so that each first transmission member 320 can drive each first rotating shaft 210 to rotate.
