[0027] The driving mechanism 5 is installed inside the chassis 1 and is used to drive the laser cutting head 2 and the slag collecting mechanism 4 to move in the horizontal direction synchronously.

[0028] When the embodiment of the present application is in use, the anti-corrosion coating 6 adopts acid- and alkali-resistant polytetrafluoroethylene or ceramic material, which can effectively prevent corrosive gases and liquids from corroding the slag hopper channel 41.

[0029] Furthermore, the filter assembly includes a filter screen 45 and an activated carbon adsorption layer 46 arranged at the outlet of the slag hopper channel 41.

Ventilation holes are provided between the outer walls on both sides of the slag collecting box 44 and the inner walls on both sides of the slag discharge hopper channel 41. When in use, by starting the fan 47, the fan 47 forms a negative pressure in the slag discharge hopper channel 41, which helps the waste slag to fall into the slag discharge hopper channel 41 and can avoid splashing, so that the waste slag falls into the slot 42 through the guide plate 43 for collection.

[0031] Furthermore, the driving mechanism 5 includes a driving motor 51, a transmission belt 52 and a screw rod 53 fixedly installed inside the chassis 1.

[0033] The working principle of the utility model is as follows: when in use, by starting the driving motor 51, the transmission belt 52 drives the screw rod 53 to rotate, and the screw rod 53 drives the moving block 55 to move left and right along the moving groove 54, thereby driving the laser cutting head 2 and the slag collecting mechanism 4 to move synchronously, so that the slag collecting mechanism 4 can collect the waste slag in time, which is convenient for cleaning. The anti-corrosion coating 6 coated on the inner wall of the slag hopper channel 41 can effectively prevent the corrosive gas and liquid from corroding the slag hopper channel 41. By starting the fan 47, the fan 47 forms a negative pressure in the slag hopper channel 41, which helps the waste slag to fall into the slag hopper channel 41 and can avoid splashing, so that the waste slag falls into the slot 42 through the guide plate 43 for collection. Through the filter screen 45 and the activated carbon adsorption layer 46, the particulate matter and harmful gas in the exhaust gas can be effectively filtered to ensure that the exhaust gas meets environmental protection standards.
