Problems solved by technology

[0004] Disclosed in Chinese patent 02232527.1 is a packing box with a bottom surface and sides with vertical folds. The packing box has a plurality of vertical folds near each side edge of the side. The problem of leakage, the disadvantage is that this kind of fold affects the beauty of the packaging box, which will greatly limit its application
However, for corrugated cardboard or low-density cardboard such as gray cardboard, the edges of the grooves formed by the current process are uneven. If you bend inwards along the grooves, the inner corner seams after bending will be very unsightly, and the packaging box The speed of encapsulation in the box is very slow, which seriously affects its use occasions; therefore, the prior art adopts the method of bending outwards along the cutting groove to form the joint angle as shown in Figure 2
Although this kind of corner can be mounted from the outside relatively conveniently, the outer corner of the corner after mounting is not a right angle with edges, the aesthetics is poor, and there are also strength problems

Embodiment 1

[0040] Corrugated cardboard was chosen as the raw material for the preparation of the packaging box. Cut the cardboard according to the box shape of the heaven and earth cover packaging box; then use half-piercing knives (double knives) to cut off the paper fiber of the cardboard (half-piercing treatment), forming two parallel cut marks 1 as shown in Figure 3, The depth of the cut marks is about 0.3 mm; and then a V-shaped cut groove 2 is excavated between the two parallel cut marks with a high-speed V-groove knife above 6000 rpm, as shown in FIG. 4 .

[0041] Apply glue (adhesive) on the V-shaped groove 2 excavated above, and then bend inwardly along the V-shaped groove 2 to form a corner structure 3 as shown in Figure 5, the corner 3 The inner corner 4 is basically a seamless structure and does not need to be mounted inside, and the outer corner 5 is a sharp right angle without a smooth transition.

[0042] Fig. 9 is the heaven and earth cover packing box prepared in this emb...

Embodiment 2

[0045] A book-shaped packaging box was prepared in the same manner as in Example 1, but the raw material used in the packaging box was low-density gray cardboard, and the depth of the cut was 0.6 mm.

[0046] Fig. 10 is a book-shaped packaging box prepared in this embodiment. The packaging box includes an inner box and an outer box, wherein the inner box is composed of an inner bottom plate 81 and an inner side plate 73 , and the outer box is composed of a cover plate 61 , an outer bottom plate 82 and an outer side plate 74 . A slot 23 is excavated between the inner bottom plate 81 and the inner side plate 73 of the inner box, and a slot 24 that can be bent is also provided between each inner side plate 73. The inner bottom plate 81 and the inner side plate 73 are of an integral structure. It is bent inwardly along the slots 23 and 24, and can be bent into the box body of the inner box. . The 61 of the outer box, the outer bottom plate 82 and the outer side plate 74 are an i...

Embodiment 3

[0049] The book-shaped packaging box is prepared by basically the same method as in Example 2, but the depth of the two parallel cuts is controlled to be 1 / 3 of the thickness of the cardboard during the preparation process, and the excavated groove is V as shown in Figure 6. Shape deformation grooving.

Abstract

The invention relates to a method of how to make packing-boxes, and the packing-boxes. And some parts or the whole of the packing-boxes are made by the following methods: (1)choosing some proper paper-boards, (2)on the inside place of the boards where need bending, delineating two parallel mars which shallower than the thickness of the boards using delineation cutters, (3)digging grooves between the parallel mars, (4)bending towards inside along with the grooves and at last making the boxes. The internal corners with the conjunctions of this invention have the instruction without chink, but the outer corners are edges and corners, having good virtual effects and high strengthen structure.

Description

technical field [0001] The invention relates to a process for producing a high-strength packaging box from cardboard, more specifically, the invention relates to a process for producing a high-strength packaging box by first scratching the cardboard and then digging out the groove method. Background technique [0002] The packaging of many products is inseparable from the packaging box, such as the packaging of daily necessities such as clothes and shoes, the packaging of communication products such as mobile phones and telephones, and the packaging of electrical products such as rice cookers and electric irons. The commonly used packaging box is a paper packaging box, because the paper packaging box is easy to recycle, even if it is used as garbage, it is easy to handle because of its cellulose content, so from the perspective of environmental protection, the paper packaging box is the preferred packaging box . Paper packaging boxes can basically be divided into two types...
