[0026] A reinforcement rod 6 is fixedly connected between the mounting plate 5 and the device body 1 , and the reinforcement rod 6 can enhance the installation stability of the mounting plate 5 and the structure above it.
[0027] The glue spraying mechanism includes a feed pump 10 and a spray head 11. The feed pump 10 is fixedly connected to the inside of the storage box 9, and the feed pump 10 and the ultrasonic sensor 4 are signal connected. The spray head 11 is fixedly connected to the outside of the storage box 9, and the spray head 11 and the feed pump 10 are connected by a pipeline. Two groups of vertically arranged through holes 12 are opened on the outside of the spray head 11.
[0028] The lifting mechanism includes a vertical plate 14, a micro motor 15, a rotating rod 16 and a gear 17. The vertical plate 14 is fixedly connected to the upper side of the mounting plate 5, the micro motor 15 and the vertical plate 14 are fixedly connected, the rotating rod 16 and the vertical plate 14 are rotatingly connected, and the rotating rod 16 and the micro motor 15 are fixedly connected.

By coordinating the two groups of through holes 12 to expand the glue spraying area, it can be ensured that the paper box is more stable after pasting, thereby greatly improving the quality of the product.
