In one embodiment, the top cover hemming outer die 2 is provided with a plurality of protruding columns 24 for positioning the top cover incoming material 100 and the ground cover incoming material 200. By the design, the protruding columns play a limiting role on the top cover incoming material and the ground cover incoming material from the side edges of the materials, and the top cover incoming material and the ground cover incoming material can be prevented from shifting during processing, so that edge folding precision is guaranteed.

In an embodiment, the operating component on the ground cover hemming station 04 is the ground cover hemming outer die 4, and the ground cover hemming outer die 4 includes a press table 41 and a shovel plate 42 for hemming provided on the press table 41.

Although the folding groove can reduce the resilience force of a part of the folding edge of the formed box body, for some box-shaped or material packaging boxes, the resilience force (or called stress) of the folding edge opening outwards is still insufficient.

For a common rectangular box body, the top cover incoming material 100 and the ground cover incoming material 200 are generally designed to comprise a bottom plate and four side plates, when the slots are cut, two long side edge folding slots and two wide side edge folding slots are cut on the top cover incoming material 100 and the ground cover incoming material 200, and when the glue is coated, glue solution can be coated in the two long side edge folding slots and/or the wide side edge folding slots.
