The glue coating mechanism 5 can apply glue to the upper part of the rectangular frame 10 and can apply pressing pressure to the folding strip 261 folded to the upper part of the rectangular frame 10.

[0039] This embodiment discloses an automatic box-sticking machine for the box, which clamps the rectangular frame 10 of the box 1 through the clamping mechanism 3 so that its through opening faces the front-to-back direction. The bottom cover plate 26 provided at the bottom of the rectangular frame 10 is supported by the bent portion 443 and flipped to a certain angle, and the glue coating mechanism 5 applies glue to the rectangular frame 10. The equipment is easy to implement industrial production and can quickly seal the bottom of the box 1.

[0040] The clamping mechanism 3 includes a bottom plate 34 disposed at the bottom of the box body 1, a cylinder 31 disposed below the bottom plate 34, a push block 32 fixedly connected to the actuator of the cylinder 31, and two rockers 33 connected at one end to the push block 32;

Before the bottom cover 26 is folded into a vertical state, the glue injection tube 54 is glued to the side of the rectangular frame 10, and then the arranged glue injection tube 54 is lifted to fold the bottom cover 26 into a vertical state. After that, the glue injection tube 54 is pressed down by the cylinder 2 51 so that the glue injection tube 54 presses the folding strip 261 onto the rectangular frame 10.
