Problems solved by technology

[0004] In the above application documents, the waterproof effect of the corrugated box can be improved by coating the outer surface of the corrugated box with waterproof paint and coating the inner surface with emulsified wax. After the printing and packaging pattern is completed, the printed pattern will be lost in the subsequent processing. There is a large friction between the corrugated paper and the processing equipment, which is easy to cause wear and tear on the pattern. At the same time, during the processing, the corrugated paper has a strong staining property, the packaging pattern is easily blocked, and it is not easy to clean up later, which leads to the overall quality of the corrugated box. The quality is greatly reduced, therefore, a new solution needs to be proposed to solve the above problems

Embodiment 1

[0042] Embodiment 1: A kind of manufacturing process of corrugated cardboard box, prepare and obtain by following steps:

[0043] Step 1, cutting, cutting the corrugated paper raw material to obtain corrugated cardboard;

[0044] Step 2, printing, transfer the cut corrugated cardboard to the printing machine, select a graphic printing plate, print the corrugated cardboard, and obtain printed matter;

[0045] Step 3, spray protection, evenly spray the protective agent on the surface of the printed matter, and carry out vacuum drying. The spraying amount of the protective agent on the printed matter is 7g / ㎡, the drying temperature is 70°C, and the drying time is 7.5min. After complete drying, the coating is obtained semi-finished products;

[0046] Step 4, slotting, and slotting the dried coated semi-finished product through a slotting machine to obtain a corrugated paper sample;

[0047] Step 5, die-cutting, die-cutting the grooved corrugated paper template through a die-cutt...

Embodiment 2-5

[0050] Embodiment 2-5: A manufacturing process of a corrugated cardboard box. The difference from Embodiment 1 is that the components of the protective agent and their corresponding parts by weight are shown in Table 1.

Abstract

The invention discloses a manufacturing method of a corrugated carton, and relates to the technical field of corrugated paper packaging. The manufacturing 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, spraying protection, specifically, evenly spraying a protective agent to the surface of the printed matter, 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,specifically, folding and bonding the die cutting sample plate through a carton bonding machine to obtain a corrugated carton finished product. In the actual application process, printed patterns arenot prone to being stained, and the overall quality of the corrugated carton can be guaranteed.

Description

technical field [0001] The present invention relates to the technical field of manufacturing technology of corrugated cardboard box, more specifically, it relates to a kind of manufacturing technology of corrugated cardboard box. Background technique [0002] Corrugated paper is a plate made of liner paper and corrugated corrugated paper formed by processing corrugated sticks.
