[0002] Cartons are the most widely used packaging products. Depending on the materials used, there are various specifications and models such as corrugated boxes and single-layer cardboard boxes. Cartons are generally made of folded cardboard. For some special uses, holes need to be opened in the cardboard.

[0003] After searching, the utility model patent with announcement number CN219806197U discloses a punching device for corrugated cardboard production, including a body, a mounting plate, a mounting block driving roller and a driven roller, a conveyor belt is provided on the driving roller and the driven roller, a rotating motor is provided on the mounting block, a transmission shaft and a rotating shaft are provided on the mounting plate, a transmission gear is fixed on the transmission shaft, a rotating gear is fixed on the rotating shaft, a connecting assembly is provided on the connecting assembly, a punching roller is installed on the punching roller, and a hole opening knife is fixed on the punching roller; the patent can continuously open holes on the corrugated cardboard, and can open multiple rows of holes at the same time, thereby improving the hole opening efficiency; it can provide support for the corrugated cardboard to prevent the corrugated cardboard from being squeezed by the hole opening knife and wrinkled or deformed; it can replace punching rollers of different specifications to improve the applicability of the device.

[0004] However, the above patent has the following shortcomings: the conveyor belt does not position the cardboard during transportation, and the cardboard is prone to tilting and shifting during movement, which can cause the punching to be offset. In addition, the cardboard may be pulled up by the rotating punching knife during the punching process, causing the cardboard to move with the punching knife, affecting the smooth punching process. To address this problem, we propose a positioning and clamping mechanism for cardboard punching. Utility Model Content
