Problems solved by technology

Although this method can effectively avoid cracks, the high humidity of the cardboard will affect the compressive strength, puncture strength and other indicators of the carton; the carton still cannot meet the requirements of relevant standards
In addition, after the corrugated carton is made, it is inefficient and expensive to paste colored paper.

Abstract

The invention relates to a continuous production line for single-paper preprinted color box corrugated boards and a technological process of the continuous production line. The continuous production lien comprises a raw paper conveying portion, a corrugated machine set portion, a face paper conveying portion, a double-layer laminator portion, a bonding and drying portion and a cutting portion. The face paper conveying portion comprises a face paper frame and a single-piece paper conveying machine, the single-piece paper conveying machine is arranged in front of the double-layer laminator, and the face paper frame is arranged in front of the single-piece paper conveying machine.

Description

Technical field [0001] The invention relates to the field of cardboard production, in particular to a continuous single-sheet paper preprinted color box corrugated cardboard production line and its technological process. Background technique [0002] The production process of corrugated color boxes is usually to first dry each layer of raw paper, and combine the layers of raw paper into corrugated cardboard according to the way of bonding, and then paste a single pre-printed colored paper on the corrugated cardboard, roll the creases, and cut it. Groove, and finally fold the cardboard into a carton along the crease. Due to the fragile texture of corrugated cardboard, many irregular cracks are easily produced on the surface of the cardboard near the indentation line during the creasing process, which seriously affects the quality of the carton; especially when the cardboard is folded into a carton, the cracks will continue to extend and expand, and the cardboard will break , Resu...
