The second glue spraying assembly 122 is located between the grabbing part 91 and the cover closing unit 8. The first glue spraying assembly 121 and the second glue spraying assembly 122 both belong to the prior art, and the structures of the first glue spraying assembly 121 and the second glue spraying assembly 122 are not described in detail herein.

During operation, the box body 131 moves forwards through the chain conveying unit 10, the first glue spraying component 121 sprays glue to the left side and the right side of the box body 131 in the process of moving forwards, and the second glue spraying component 122 sprays glue to the front edge and the rear edge of the lower side face of the box cover 132 in the process of moving when the box cover 132 moves to the side close to the cover closing unit 8 through the conveying component 92, so that the glue can be adhered to the box cover 132 and the box body 131 all around after the box cover is closed.

Further, as shown in fig. 33, in order to adapt to heights of different box bodies 131, the first glue spraying assembly 121 is slidably connected to the frame body of the chain conveying unit 10 through a sliding assembly, and an eighth driving member 1211 for driving the first glue spraying assembly 121 to slide up and down is disposed between the first glue spraying unit and the frame body of the chain conveying unit 10. As a specific implementation manner, in the embodiment, the second driving component 36 employs a self-guiding electric slide rail, a fixed side of the electric slide rail is fixedly connected to the frame body of the chain conveying unit 10, and a moving side of the electric slide rail is fixedly connected to the first glue spraying assembly 121.
