[0002] Paperboard is often made into packaging cartons, and the packaging cartons bear the important responsibility of protecting products as an indispensable part of modern logistics. The volume of the carton needs to adapt to different sizes of commodities, and the paperboard generally needs to be cut before entering the single paper offset press for printing. The purpose is to make the size of the paperboard meet the requirements of the product and the printing machine specifications. In order to ensure smooth operation of the offset press and accurate overprint, there are relatively strict requirements for paperboard printed by the offset press, especially paperboard printing.

At this time, by rotating the second lead screw, the second lead screw is moved downward in cooperation with the second lead screw sleeve, so as to drive the pressing plate to move downward, so that the pressing plate is tightly pressed on the upper surface of the paperboard, and the paperboard is fixed. It can prevent the paperboard from shifting during cutting, which affects the cutting quality.

[0004] However, the above-mentioned device still has some shortcomings in actual use. The most obvious one is that the device uses a pressing plate to press the paperboard downward to prevent the paperboard from shifting. In actual use, the operator cannot accurately adjust the pressing plate to the appropriate height, which may cause the paperboard to be damaged or deformed due to excessive pressure from the pressing plate. If the pressure is too small, the paperboard may loosen during cutting, affecting the cutting effect. In addition, after cutting the paperboard, the operator needs to manually rotate the screw to drive the pressing plate to rise and then remove the paperboard. Then the operator needs to rotate the screw again to cut the next paperboard, which is very troublesome and inefficient.

[0005] Therefore, it is necessary to invent a paperboard cutting machine to solve the above-mentioned problems. Utility model content
