This utility model discloses a pressing device for paper packaging materials. A cylinder is installed at the top center of the support frame, and a push rod is connected to the bottom of the cylinder. A connecting plate is installed at one end of the push rod, and the push rod is fixedly connected to the top center of the connecting plate. Multiple springs are installed at equal intervals at the bottom of the connecting plate, and a pressure plate is connected to the connecting plate through the springs. Telescopic rods are symmetrically installed on both sides of the top of the pressure plate between two springs, and the top of the telescopic rods is fixedly connected to the connecting plate. This utility model is equipped with a compression component. The cylinder compresses the pressure plate to compress the packaging material, and the springs are compressed, so that the pressure plate applies force evenly to the paper packaging material during pressing, avoiding excessive pressure that could damage the paper packaging material. The telescopic rods fix the positional relationship between the pressure plate and the connecting plate, preventing the springs from deflecting during pressing and causing the pressure plate to shift its pressing position.
