When cutting is needed, cutting materials are placed on the upper end face of the bearing block 28, the vacuum aspirator 21 is started at the moment to aspirate, when thin materials are cut, the vacuum aspirator 21 can adsorb the cut materials on the upper end face of the bearing block 28 when aspirating, the power motor 15 is started at the moment to drive the power rotating shaft 13 to rotate so as to drive the nursing box body 34 to rotate, the nitrogen machine 17 is started at the moment, nitrogen generated by the nitrogen machine 17 can comprehensively enter the rotating shaft cavity 14 to enter the first space 35 so as to enter the two second flow passages 51, and the heat conducting block 39 conducts a large amount of heat to expand the expansion block 45 so as to push the corresponding reversing sliding plate 46 to slide due to laser cutting of the laser emitting head 40, thereby driving the corresponding reversing rack 47 to slide, thereby driving the corresponding reversing gear 49 to rotate, thereby driving the corresponding reversing plate 52 to rotate, thereby causing the nitrogen to enter the third flow channel 53 and be ejected from the exhaust pipeline 36 to the cutting position, simultaneously, the air suction space 27 sucks air, thereby sucking the cutting scraps into the scrap suction port 29, and simultaneously sucking the blown nitrogen, thereby accelerating the circulation of the nitrogen and further accelerating the nitrogen to contact the cutting end face, thereby improving the flatness of the cutting end face, avoiding the generation of scale on the cutting surface, thereby causing the appearance of false welding, accelerating the cutting speed, simultaneously, the scraps enter the air suction flow channel 24 and are intercepted by the intercepting filter 23 and fall into the collecting space 22, and closing the laser assembly 20 after the cutting is completed, thereby dissipating heat of the heat conducting block 39, so that the expansion block 45 is contracted, the reversing rack 47 is reset, the reversing plate 52 is reset, nitrogen enters the first flow passage 43 to be cleaned, the corrugated air bag 42 is inflated, the cleaning slide column 38 slides downwards, the cleaning slide column 38 abuts against the laser emitting head 40 close to the end face of the laser emitting head 40, the nursing box body 34 rotates, the cleaning slide column 38 is driven to rotate around the laser emitting head 40, the control slide rod 41 slides in the abutting slide way 33, the control slide rod 41 slides up and down in a reciprocating mode, the corrugated air bag 42 is inflated and deflated in a clearance mode, the cleaning slide column 38 slides up and down in a reciprocating mode, and the cleaning slide column 38 rotates on the laser emitting head 40 and slides up and down in a reciprocating mode, the laser emitting head 40 is cleaned, so that scraps generated by cutting are prevented from contacting the laser head and adhering to the laser head.

The above description is only an embodiment of the invention, but the scope of the invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the invention. Therefore, the protection scope of the invention should be subject to the protection scope defined by the claims.
