The feeding mechanism 2 is used to deliver the packaging material to the lower side of the taking mechanism 3. The taking mechanism 3 is used to lift the upper packaging material to the upper side. The gluing mechanism 4 is used to coat glue on the upper surface of the lower packaging material. The gluing mechanism 4 is arranged below the taking mechanism 3 and reciprocally moves along the feeding direction of the feeding mechanism 2. The gluing mechanism 4 can move above the feeding mechanism 2, and the moving track is from one end of the packaging material to the other end, and finally completes the coating of glue. The gluing mechanism 4 comprises a lifting assembly 41 and a gluing assembly 42 arranged on the lifting end of the lifting assembly 41.

The gluing assembly 42 comprises a gluing roller 421. The axis of the gluing roller 421 is arranged perpendicularly to the feeding direction. When coating glue, the gluing roller 421 moves to the lower side of the taking mechanism 3 and moves downward under the drive of the lifting assembly 41 to contact the lower packaging material on the feeding mechanism 2 to coat glue on the lower packaging material. After the coating of glue is completed, the taking mechanism 3 is lowered to press the upper packaging material thereon on the lower packaging material on the feeding mechanism 2.

[0034] The gluing mechanism 4 of the application uses glue as medium, heats the glue and coats the glue on the lower packaging material through the horizontal movement of the gluing mechanism 4.
