The punching frame 1 is provided with a blowing component 4, and the blowing component 4 includes a plurality of blowing areas and blowing ports arranged toward the paper scrap storage box 51. The blowing component 4 blows paper scraps into the paper scrap storage box 51 through the blowing ports.

[0026] The paper to be punched is conveyed forward by the conveying mechanism 10, and the paper passes through the first conveying roller 13, the active guide roller 18 and the second conveying roller 14 in sequence. When passing through the active guide roller 18, it cooperates with the punching mechanism 2, and the punching mold mounted on the punching guide roller 21 punches holes in the paper, so that holes are formed on the paper. After the holes are punched, the paper scraps at the hole positions are blown to the paper scrap storage box 51 by the blowing port arranged on the punching machine frame 1, and are recovered through the paper scrap storage box 51. There is no need to manually remove the paper scraps. Since the weight of the paper scraps is light, the blowing component 4 can blow the paper scraps from the surface of the paper to the paper scrap storage box 51, saving labor costs and facilitating subsequent paper processing.

[0033] The paper scrap storage box 51 includes a box body, and a chip outlet 53 is formed at the bottom of the box body. The chip outlet 53 is provided with a control port for controlling the removal of paper scraps. The control port includes a pair of parallel and spaced guide mounting plates 54. The guide mounting plates 54 are arranged tilted, and a control plate 55 is slidably installed between the two guide mounting plates 54. The inner side walls of the guide mounting plates 54 are formed with inner sliding grooves 56 for installing the control plate 55 along the length direction; the paper scraps entering the box body can be temporarily stored in the box body, and the control plate 55 is pressed against the chip outlet 53 to achieve temporary storage; when the paper scraps temporarily stored in the box body need to be discharged, the control plate 55 is slid, and the control plate 55 moves outward along the inner sliding groove 56 of the guide mounting plate 54, and the paper scraps can be discharged from the chip outlet 53.

[0034] In one embodiment, the box is equipped with an exhaust device, which includes an exhaust module 57 disposed outside the box, an exhaust end 58 of the exhaust module 57 inserted into the box, and a filter is installed at the exhaust end 58. After some paper scraps are blown to the guide expansion opening 52 at the top of the box by the blowing assembly 4, they will not fall into the box. The exhaust module 57 can generate negative pressure in the box, and the paper scraps near the guide expansion opening 52 can be sucked in, reducing the amount of residual paper scraps.

[0035] In addition, side panels can be installed around the punching frame 1 to form a negative pressure space inside the punching frame 1. In conjunction with the blowing assembly 4, paper scraps inside the punching frame 1 can be sucked into the guide expansion 52 and enter the box body. The filter net can isolate the paper scraps from the exhaust module 57 to prevent adsorption blockage.
