[0022] The gluing mechanism, the gluing mechanism includes a U-shaped plate 2 fixedly connected to the upper end of the base 1. A hollow rod 3 is inserted into the side wall of the U-shaped plate 2. A gluing roller 4 is fixedly connected to the side wall of the hollow rod 3. The gluing roller 4 penetrates through the side wall of the U-shaped plate 2. A plurality of first holes 5 are opened on the side wall of the hollow rod 3. A plurality of second holes 6 corresponding to the plurality of first holes 5 one by one are opened on the side wall of the gluing roller 4. The side wall of the U-shaped plate 2 above the hollow rod 3 is slidably connected with an L-shaped plate 8. A rotary joint 9 is fixedly connected to the side wall of the L-shaped plate 8 close to the gluing roller 4 through a bracket. One end of the hollow rod 3 is fixedly connected to the side wall of the rotary joint 9. The end of the rotary joint 9 far from the hollow rod 3 is fixedly connected with a conveying pipe 10.

[0023] Furthermore, since a plurality of second holes 6 are opened on the side wall of the gluing roller 4, the contact length of the gluing roller 4 on the upper surface of the cardboard can be adjusted, thereby adjusting the gluing size on the cardboard of the gluing roller 4, enabling different-size gluing treatments on the cardboard, being applicable to different-size labels, and avoiding the need to replace the corresponding gluing wheel according to the size of the label on the cardboard at present, which wastes a lot of time during the operation of this model change.

[0024] It should be noted that during the conveying of the cardboard on the conveying roller 16, at this time, the side wall of the gluing roller 4 is in contact with the upper surface of the cardboard. The end of the conveying pipe 10 far from the rotary joint 9 is connected to an external glue pump for pumping glue into it, which is the prior art.
