After the second cutting station 124 completes die cutting the other two sides, the discharging part 350 picks up the stack of sheets and conveys the stack of sheets to the discharging conveyor 310 to complete discharging. The second fixing seat 353 of the discharging part 350 is provided with a second gripping device, the second gripping device includes a second upper gripping head 355, a second lower gripping head 356, a second upper gripping head driving cylinder 357 and a second lower gripping head driving cylinder 358, the second upper gripping head 355 is disposed above the supporting part 110, and the second lower gripping head 356 is disposed in a gap formed between the supporting part 110 and the machine base 100, and grips the paper stack placed on the second through-groove 132 of the supporting part 110. The second gripper assembly grips the stack of sheets and then moves the stack of sheets under the influence of the second drive assembly to transport the stack of sheets from the second cutting station 124 to the outfeed conveyor 310. The width of the paper stack is larger than that of the second through groove 132, after the discharging component 350 loosens the paper stack, the paper stack conveyed to the tail end of the second through groove 132 is in contact with the discharging conveyor belts 310 arranged on two sides of the tail end of the second through groove 132, and is far away from the second through groove 132 under the driving of the discharging conveyor belts 310, so that discharging is completed.

The machine base is further provided with a protective device, the protective device comprises a first baffle 510 and a second baffle 520, the first baffle 510 is arranged between the feeding station 121 and the first paper cutting station 122, and the second baffle 520 is arranged between the second paper cutting station 124 and the discharging conveyor belt 310. The first baffle 510 is arranged on one side of the first paper cutting station 122, the second baffle 520 is arranged on one side of the second paper cutting station 124, and the paper cutting operation on the first paper cutting station 122 and the second paper cutting station 124 can be isolated and protected, so that the safety of an operator is protected. It will be appreciated that the first and

second baffles
