The press box forming mechanism 23 also includes two gray board bending retaining rods 236 arranged below the gray board guide rail 2102 for pre-bending the two ends of the gray board. The assembly is away from the side of the gray board feeding device 1 . When the gray board after gluing is transported to the right below the box pressing die 233, the box pressing motor 234 drives the box pressing die 233 to move vertically downwards, and the gray board is pressed into a box shape. The molten glue will glue the box into shape.

Specifically, a method for forming a box body using the above-mentioned fully automatic glue spraying and corner pasting machine includes the following steps:

S10, feeding: the gray board feeding device 1 transports the gray board to the gray board conveying mechanism 21 of the glue spraying forming device 2;

S20, positioning: the gray board conveying mechanism 21 positions the gray board, and pushes the gray board to the position of the glue spraying mechanism 22;

S30, gluing: the gray board conveying mechanism 21 pushes the gray board to pass under the glue spraying mechanism 22, and at the same time, the glue spraying mechanism 22 applies glue to the pre-opened V-shaped groove on the gray board;

S40, box press forming: the gray board conveying mechanism 21 pushes the gray board that has been glued to the position of the box press forming mechanism 23, and then the box press forming mechanism 23 presses the gray board into a box shape, and utilizes the melting in the V-shaped groove of the gray board Glue to form the box;

S50. Pressure holding: the box pressing mechanism 23 presses the gray board box into the forming pressure holding device 3, and then the forming pressure holding device 3 clamps and fixes the gray board box so that the molten glue is fully solidified.
