At this time, the moving plate 26 drives the pressure roller 27 to move up and down under the restriction of the guide rod 28, so as to realize the height adjustment of the pressure roller 27. When the cardboard reaches the top of the bearing plate 34, the hydraulic cylinder 331 is activated. The hydraulic cylinder 331 drives the cutting blade 333 to move downward. Before the cutting blade 333 contacts the cardboard, the pressure plate 337 contacts the cardboard. While the hydraulic cylinder 331 continues to descend, the pressure plate 337 stably compresses the elastic element 336 under the restriction of the slide rod 335. Under the action of the restoring force of the elastic element 336, the cardboard can be effectively fixed to prevent the cardboard from slipping during cutting. After the cutting blade 333 cuts the cardboard, it will enter the groove of the cutting groove 36. At this time, the restoring spring 37 is compressed, which can buffer the cutting blade 333.
