The distance of the piston rod of the micro cylinder 19 is adjusted according to the thickness of the cardboard. After the piston rod of the micro cylinder 19 is pushed out, it drives the connecting plate 23 to rise, thereby driving the cardboard on the U-shaped placement seat 20 to approach the slitting blade 14 rotating at a high speed. When the slitting blade 14 contacts the surface of the multi-layer cardboard, the cardboard is automatically cut. The U-shaped placement seat 20 can also slide on the guide rail 24 through the positioning sliding sleeve 26 to realize automatic adjustment of the slitting position of the multi-layer cardboard.
