[0022] The anti-drop mechanism 5 includes a fixed block 51, which is fixedly connected to the bottom end of the movable plate 3. The movable plate 3 and the fixed block 51 are an integrated structure. An opening 52 is provided on one side of the fixed block 51, and a squeezing plate 53 is slidably connected to the opening 52. The squeezing plate 53 is tilted upward, and a spring 54 is fixedly connected to one side of the squeezing plate 53. One end of the spring 54 is fixedly connected to the opening 52, and an elastic pad is fixedly connected to one side of the squeezing plate 53.

[0023] Working process: when stacking cardboard, the mounting frame 1 is moved downward, the mounting frame 1 drives the two movable plates 3 to move downward, the movable plate 3 drives the fixed block 51 to move, and the fixed block 51 drives the squeezing plate 53 to move, so that the cardboard is located between the two squeezing plates 53, and the motor 2 is started and drives the bidirectional screw 4 to rotate. After the bidirectional screw 4 rotates, the two movable plates 3 move toward each other, so that the two squeezing plates 53 move toward each other, and the squeezing plates 53 move toward each other for a distance and contact and squeeze the side of the cardboard. After being pressed, the squeezing plates 53 move toward the opening 52, and the squeezing plates 53 move a certain distance and are flush with the opening 52. At the same time, the squeezing plates 53 squeeze the spring 54 after moving, and the spring 54 generates elastic force after being pressed, and the squeezing plates 53 are tilted upward. The elastic force generated by the spring 54 causes the squeezing plates 53 to push the cardboard upward, and the cardboard is subjected to an oblique upward thrust. During the stacking process of the cardboard, it will not fall under the push of the squeezing plates 53.

[0024] Embodiment 2: In embodiment 1, when the cardboard is tilted and supported by the squeezing plate 53, the supported cardboard is easily bent upward, thereby reducing the quality of the cardboard.

The upper end of the rotating shaft 62 is fixedly connected to a turntable, and the bottom end of the rotating shaft 62 is fixedly connected to a threaded rod 63. A pressing plate 64 is slidably connected to the movable plate 3, and the pressing plate 64 and the extrusion plate 53 are located on the same side. A second threaded hole is provided on the pressing plate 64, and the threaded rod 63 cooperates with the second threaded hole. The rotating shaft 62 is driven to rotate by the turntable, and the rotating shaft 62 drives the threaded rod 63 to rotate. After the threaded rod 63 rotates, the pressing plate 64 moves downward by a set distance. When the extrusion plate 53 extrudes and fixes the cardboard, the extrusion plate 53 contacts the upper end surface of the cardboard, and the upper end surface of the cardboard is limited. When the extrusion plate 53 extrudes the cardboard, the cardboard will not bend upward.
