A kind of manufacturing method of high-strength offset printing color plate

Abstract

The invention relates to a method for making high-strength offset printing color plates, which includes installing the inner paper and corrugated base paper on the base paper support and aligning them with a photoelectric induction device; respectively heating them through preheating wheels; feeding the corrugated base paper into single-sided The adhesive is applied on the machine, and it is bonded with the inner paper to form a single-sided corrugated paper; the steam atomized water is humidified, and the preheating wheel is used to heat; the corrugated paper is sent to the overpass conveyor, and it is conveyed straight forward in the form of bridge conveying; according to the established The specifications are cut to become single-sided corrugated cardboard; the single-sided corrugated cardboard is sent to the gluing position; after the adhesive is applied, it is laminated with the printed color face paper; the colored corrugated cardboard is stored front and back through the flipping device. The invention effectively controls the moisture content of the paper in the whole process, the strength of the cardboard can be improved, and the physical index of the carton in the traditional craft can be increased by 20%; the pressed cardboard can be directly die-cut, and the production efficiency is high.

Description

technical field [0001] The invention relates to a method for manufacturing a high-strength offset printing color plate, in particular to a method for manufacturing a three-layer offset printing color plate. Background technique [0002] The traditional manufacturing process of colored corrugated cardboard mainly uses high-temperature baking of the inner paper to make it bonded to the corrugated paper, and then produces a single-corrugated cardboard through an adhesive; Cardboard lamination, this process is generally that the paper feeding direction of the single-wale cardboard is the direction of the vertical corrugation, and the amount of adhesive used is generally 30-40g; the mounted colored cardboard can be placed for 8-12 hours before it can enter the next step Process Die-cutting into boxes. [0003] The disadvantages of this manufacturing process are: high-temperature baking will cause most of the moisture in the paper to lose, destroy the fibers of the paper, and red...

Problems solved by technology

[0003] The disadvantages of this manufacturing process are: high-temperature baking will cause most of the moisture in the paper to lose, destroy the fibers of the paper, and reduce the folding strength of the cardboard; Manual re-correction wastes cost and time; at the same time, excessive glue application makes the cardboard soft, reducing the edge pressure, burst resistance and compressive strength after boxing, and at the same time, the storage time is too long due to the soft cardboard. Prolonged lead time, reduced production efficiency, and is not conducive to protecting the contents
