Graphic printing processing method for manufacturing of cardboard box

Abstract

The invention relates to a graphic printing processing method for manufacturing of a cardboard box, in particular to a coating device after manufacturing of a cardboard box by using graphic printing. The coating device comprises a conveying machine frame, a roller type conveyor, a belt type conveyor, a paper board guiding mechanism, a discharging coating roller group and a smoothing scraper plate mechanism, wherein the paper board guiding mechanism comprises a front retainer frame, two side retainer plates and a bidirectional adjustable screw rod; the smoothing scraper plate mechanism comprises a central rotary shaft and eight scraper plate assemblies. By adopting the method and the device provided by the invention, a pre-coating film can be smoothed in a process of performing graphic printing of the paper board and then performing coating, bubbles caused by coating can be squeezed out and then discharged completely, so that the situations of virtual pressing and folds can be avoided, the compactness and the smoothness of coating films are ensured, and the problems of lamination of bubbles, non-compactness of lamination and lamination folds caused by only simply performing hot pressing in a conventional coating film processing procedure can be solved.

Description

technical field [0001] The invention relates to the technical field of cardboard box processing, and specifically proposes a cardboard box production graphic printing processing method. Background technique [0002] As an indispensable part of modern logistics, packaging cartons bear the important responsibility of packaging, protecting products and looking beautiful. They are the most widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications. and model. [0003] During the production and processing of cardboard boxes, it is generally necessary to print corresponding graphic and text signs on the surface of the cardboard boxes. It is mainly used to display the graphic information of the appearance of the inner packaging product; after the cardboard is printed with a pattern, the surface of the printed graphic is generally covered with a film according to actual needs, so as t...

[0003] During the production and processing of cardboard boxes, it is generally necessary to print corresponding graphic and text signs on the surface of the cardboard boxes. It is mainly used to display the graphic information of the appearance of the inner packaging product; after the cardboard is printed with a pattern, the surface of the printed graphic is generally covered with a film according to actual needs, so as to achieve the purpose of protecting the printed coating and improving the gloss; but in In the traditional printing and laminating process, it is often simply hot-pressed and laminated, so there are often air bubbles, virtual pressure, and film wrinkles after lamination, which affects the quality of the lamination.
