[0029] It should be noted that when the computer printing paper 3 moves to the left, it will contact the bent plate 45. The bent plate 45 is arranged in an arc shape, which can enable the computer printing paper 3 to move better, thereby driving the pressing plate 48 to move upward, thereby causing the slide bar 47 to move upward, thereby compressing the spring 46. At the same time, the limit rod 43 arranged on the left side will move upward, ensuring the stable movement of the pressing plate 48, thereby flattening the computer printing paper 3 so that the computer printing paper 3 will not curl, thereby achieving a better slitting effect.

[0035] It should be noted that by starting the motor 1 21, the left wheel 24 rotates counterclockwise, thereby driving the conveyor belt 23 to rotate counterclockwise, placing the computer printing paper 3 on the conveyor belt 23, and the conveyor belt 23 will drive the computer printing paper 3 to move to the left, and then start the set motor 27, so that the rotating shaft 28 rotates clockwise, thereby driving the two slitting blades 29 to rotate clockwise. The set slitting blades 29 are located in the middle position of the conveyor belt 23, and then cut the computer printing paper 3 moving to the left. After cutting, the computer printing paper 3 continues to move to the left and then falls into the collection box 22, thereby achieving the collection effect.
