Method and device for improving die-cutting pit explosion of color box

Abstract

The invention discloses a method and a device for improving a die-cutting pit explosion of a color box, wherein the method comprises the steps of: arranging a humidifying device to humidify a die-cutting plant, and keeping air humidity in the die-cutting plant in a first humidity range; and starting a die cutting machine, and when the air humidity is in the first humidity range, conducting die-cutting indentation and folding on a laminated color box paperboard. For the method and the device, by controlling the humidity of the die cutting plant, the water content of the color box paperboard is controlled, so that the purpose of improving die cutting pit explosion is achieved without directly wetting the color box paperboard with water, adverse effects on the printing quality of color box surface paper are avoided, and the possibility of weakening the strength of the color box is reduced. Moreover, the method can control the water content of the color box paperboard in the whole plant without adding procedures and manpower, so that the method is low in cost and good in effect and is green, safe and harmless.

Description

technical field [0001] The invention relates to the field of color box beer cutting, more specifically, to a method and device for improving the cracking of color box beer cutting. Background technique [0002] With the continuous improvement of people's living standards and the gradual prosperity of the commodity economy, paper packaging materials with light weight, low price and environmental protection are popular. Among them, the demand for colorful packaging cartons with advertising functions and exquisite printing is increasing. bigger and bigger. Colored packaging cartons (hereinafter referred to as color boxes) refer to cartons that are printed on a sheet PS plate first, and then undergo mounting pits, beer cutting and nailing / gluing processes, also known as color boxes. Beer cutting is an indispensable key link in the production and molding process of color box products. The color box after the mounting hole has indentation after beer cutting. During the subsequen...

AI Technical Summary

Problems solved by technology

[0004] 1. Reasonable matching of materials, such as choosing lining paper and face paper with better folding resistance, such as surface coating of cardboard, but the cost will increase accordingly;

[0005] 2. Improve the cracking of the color box in the beer cutting process, such as choosing a widened and thickened arc-back beer knife to press the line, but it can only slightly reduce the cracking, and cannot fundamentally solve it;

[0006] 3. If you directly apply wet water to the surface of the cardboard to control the moisture, but it will inevitably affect the printing part, affecting the printing quality and the strength of the cardboard

[0007] Therefore, the existing technology for improving color box bursting pits cannot be simultaneously considered in terms of environmental protection, cost, effect and stability.
