Manufacturing method of transparent folding plastic packaging box

Abstract

The invention relates to a manufacturing method of a transparent folding plastic packaging box. The manufacturing method comprises the following steps that semi-cutting treatment is conducted on folding lines or near the folding lines; or, mark pressing is conducted on the folding lines through pressing lines, and semi-cutting treatment is conducted on the folding lines or near the folding lines after mark pressing; and semi-cutting processing treatment comprises the steps that a material with a certain thickness is cut, and after cutting, part of the material with the certain thickness is not cut. The manufacturing method of the transparent folding plastic packaging box has the beneficial effects that according to the manufacturing method, the problem that the folding lines are not liable to be folded is solved, and the folding lines do not need to be pre-folded; full-automatic production processing can be achieved, and the one-person multi-machine scheme is achieved; the problem of the low speed of high-frequency equipment is solved, the effects of energy saving, labor saving, space saving and processing cost saving are better than those of a high-frequency machine, the high-frequency equipment does not need to be purchased; and all equipment and moulds for manufacturing a color box can be used, and the packaging box is formed by folding of side pieces of box pieces according to the folding lines (10).

Description

technical field [0001] The invention relates to the technical field of packaging box manufacturing, in particular to a manufacturing method of a transparent folding plastic packaging box. Background technique [0002] With the continuous development of society and the gradual improvement of people's packaging requirements, the original paper packaging boxes can no longer meet their packaging requirements. Everyone hopes that the packaging box will become more and more beautiful, and the gold content of the product can be improved after packaging. , it is best to be able to see the products packaged inside at a glance. The transparent folding plastic box is a new type of packaging box that came into being under this demand. The transparent folding plastic box can not only meet its appearance and intuitive requirements, but also can Resists moisture and moisture. At present, there are two main manufacturing methods that are common in the market: one is the ordinary transparen...

AI Technical Summary

Problems solved by technology

The indentation lines of existing transparent plastic boxes are all indentation lines with a certain depth pressed out by ordinary crimping lines. Appropriate pressure should be applied when marking the line. If the pressure is too large, it will easily break, and if the pressure is too small, it will not be easy to fold.

For plastic sheets or coils with different materials and thicknesses, it is necessary to readjust the pressure when stamping the creasing line, so it often produces a certain scrap rate and affects work efficiency.

Not only that, when the creasing line is pressed to fold the packaging box, the packaging operation will be time-consuming and laborious because the creasing line cannot be too deep

Generally, it is necessary to arrange workers to pre-fold the product before packaging, which is particularly time-consuming and laborious; in addition, during the process of packaging items or after repeated folding and bending, cracks or even breaks often appear at the indentation line, so the scrap rate is high. Not only reduces the strength of the indentation line, but also has poor aesthetics

[0004] Another manufacturing method is that the high-frequency machine using the high-frequency principle can emboss the effect of the indentation line. The indentation line embossed by this process is soft and easy to fold, and the indentation line can be easily folded, but the process The disadvantage is that the processing speed is very slow. At present, the processing speed of ordinary high-frequency equipment is about 400 strokes per hour. All loading and unloading are manually operated by humans. People will always be tired and easily cause danger. With the gradual increase of automation , There are also a very small number of fully automatic high-frequency machine equipment. This equipment solves the problem of automatic loading and unloading, automatic embossing and cutting, and the speed has reached a new speed of about 800 strokes per hour, but the principle of high-frequency technology has already been determined. The embossing speed of the high-frequency machine has reached the limit, and the speed cannot be greatly increased.

[0005] Through the above case, we can find that the creasing line produced by the crimping line of the ordinary transparent plastic packaging box is not easy to fold, and is easy to crack or break, and manual pre-folding must be arranged before packaging, which is time-consuming and labor-intensive. Manual pre-folding Surface scratches and scratches are easy to occur. Because the crease line is too shallow, the folded plastic box is not straight and beautiful, and it is easy to warp; the high-frequency soft line manufacturing process solves the problem that the crease line is not easy to fold However, due to its slow speed and high energy consumption, it has not been able to produce in large quantities

It is not difficult to see that neither of these two methods can meet the needs of easy folding and high-speed fully automated mass production at the same time.
