When working, all folds are formed by die stamping to fold and assemble the cardboard 110. It is necessary to fold the fourth cardboard 15, the first cardboard 5, the second cardboard 9 and the third fixed plate 17 on one side of the eighth side plate 13. After folding, they are hidden in the eighth side panel 13. The first cardboard 5, the second cardboard 9, the third cardboard 14 and the second fixed plate 16 on one side of the seventh side panel 12 need to be folded and hidden in the seventh side panel 12, and the fourth side panel 8 is folded back to the outside of the third side panel 7. In this way, when packing the carton, the problem of the knife line of the inner box being exposed is avoided, thereby reducing the problem of paper scraps and dust in the inner box falling into the box, so that when the carton is in use, the protection effect of the contents is reduced, and the use effect of the carton is improved.
[0022] like Figures 1 to 3 As shown, all surfaces of the cardboard 110 are coated with UV oil; the UV oil is evenly arranged on the surface of the cardboard 110. During operation, by applying UV oil on the cardboard 110, the paper scraps and dust existing on the surface of the cardboard 110 are solidified.
