Fold, preparation method thereof, paper box and double-edge reverse-press cutting die

Abstract

The invention relates to paper post-printing processing technology, in particular to a fold, a preparation method thereof, a paper box and a double-edge reverse-press cutting die. The fold comprises a paper board, wherein the reverse surface of the paper board has a dent and the front side of the paper board has two tool marks of which the directions are consistent with that of the dent, and the positions of the two tool marks correspond to the two edges of the dent respectively. The preparation method for the fold comprises the following steps of: S1, providing the paper board, an upper die and a bed die; and S2, punching. The upper die provided by S1 comprises a dent line and a hanging head hole cutting tool mark; and the bed die provided by S1 has an opposite-cutting half-through tool mark, and the positions of the opposite-cutting half-through tool mark correspond to that of the dent line of the upper die. The paper box comprises a hanging head hole which is formed by folding the pre-punched paper board, the dent is formed on the inner side of the folded position, and the two tool marks are formed on the outer side of the folded position. The double-edge reverse-press cutting die has two tool marks of which the directions correspond to that of the dent line, and the two tool marks are positioned on the two edges of the dent line respectively.

Description

technical field [0001] The invention relates to the post-press processing technology of paper products in the packaging and printing industry, in particular to a crease and a preparation method thereof, a paper box, and a double-peak back-pressing knife mold. Background technique [0002] The hanging head hole is used to hang the goods for sale on the hooks in the supermarket or shopping mall to display the goods. The head-hanging hole is generally a horizontal elongated hole, and a section of circular arc is provided upwards in the middle of the elongated hole to facilitate the hook to penetrate into the head-holding hole. [0003] Hanger holes are generally punched out together with the box shape and various indentations during the die-cutting process. In order to increase the strength of the hanger holes, the parts of the hanger holes are made of double-layer cardboard. refer to figure 1 When punching, take a centering crease 002 as the axis of symmetry, and punch out t...

AI Technical Summary

Problems solved by technology

In the process of folding weighing, part of the material is cut off due to the part of the die-cut hanging head hole 011, and its ability to resist bending is significantly reduced. figure 2 Also, stress concentration occurs at the 011 part of the hanging head hole, so that the hanging head hole is deformed, affecting the processing quality, and even causing scrapping

[0005] The above problems can be solved by using thicker cardboard, but this will increase the cost of carton materials and waste resources
