Preparation and processing method of corrugated carton

Abstract

The invention discloses a preparation and processing method of a corrugated carton, and relates to the technical field of corrugated paper processing. The preparation and processing method comprises the following steps of 1, cutting, specifically, cutting a corrugated paper raw material to obtain a corrugated paperboard; 2, printing, specifically, conveying the cut corrugated paperboard to a printing machine, selecting an image-text printing plate, printing the corrugated paperboard, and obtaining a printed matter; 3, line pressing and spraying protection, specifically, folding the printed matter to form a longitudinal indentation and a transverse indentation through a line pressing wheel, marking a notch line through pre-mould pressing, spraying a shape fixing protective agent at the longitudinal indentation, the transverse indentation and the notch line, and obtaining a coated semi-finished product after complete drying; 4, slotting, specifically, slotting the dried coated semi-finished product through a slotting machine to obtain a corrugated paper sample plate; 5, die cutting, specifically, performing die cutting on the grooved corrugated paper sample plate through a die cutter, and obtaining a die cutting sample plate; and 6, box pasting. The corrugated carton obtained by the preparation and processing method has good edge compression strength.

Description

Technical field [0001] The invention relates to the technical field of corrugated paper processing, and more specifically, it relates to a method for preparing and processing corrugated paper boxes. Background technique [0002] Corrugated paper is a board formed by bonding liner paper and corrugated paper formed by corrugated stick processing. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. , Can be used as packaging for food or digital products, relatively environmentally friendly and widely used. [0003] A Chinese invention patent application document with the publication number CN107042654A discloses a method for producing corrugated paper packaging boxes, which includes the following steps: 1) cutting: cutting the corrugated cardboard into the required shape with a die cutting machine; 2) pressing the line : Fold the carton with a creasing wheel to produce longitudina...

AI Technical Summary

Problems solved by technology

[0004] In the above application documents, the carton is folded out of longitudinal and transverse indentations by creasing wheels, and then slots are cut out on the corrugated cardboard to allow the upper and lower flaps to be folded smoothly, and the excess cardboard is cut off to ensure production. The size of the produced carton is accurate, but in the above operation process, the structure of the corrugated paper at the incision is easy to change during the process of slotting and cutting off the excess cardboard, and the strength is greatly reduced after the deformation, which leads to the overall edge compressive strength of the obtained corrugated carton. Poor, poor applicability, therefore, need to propose a new solution to solve the above problems
