Problems solved by technology

[0004] Large-scale production cannot be carried out with the current technology. Corrugated paper itself cannot be preserved for a long time in a relatively humid environment, and its strength cannot be guaranteed. Moreover, the types of corrugated cardboard produced are relatively single, which cannot meet the diverse needs of the market.

Abstract

The invention relates to a technology for making a high-strength waterproof composite vertical corrugated board. The technology comprises the following steps: making a kraft paper, and respectively winding the kraft paper around a first paper roller to a seventh paper roller which are sequentially arranged top to bottom; arranging the first paper roller at the feeding port of the upper surface paper channel of a double-sided machine, molding the kraft paper on the second paper roller by an E corrugating machine to form an E corrugated paper, arranging the third paper roller and the fifth paperroller at the feeding port of the core layer paper channel of the double-sided machine, molding the kraft papers on the fourth paper roller and the sixth paper roller by a C corrugating machine to form a C corrugated paper, and arranging the seventh paper roller at the feeding port of the bottom surface paper channel of the double-sided machine; arranging the output end of the double-sided machine at the feeding port of a compounding device, outputting all papers through the double-sided machine, feeding all the papers into the compounding device, and performing drying to obtain a finished product, wherein compacting rollers for compacting the board are arranged in a drying channel; and cutting the finished board as demanded, and warehousing the cut finished board. The composite corrugated board made by the technology has a high strength and a high compression resistance, and is suitable for all kinds of exquisite packaging.

Description

technical field [0001] The invention relates to a production process of corrugated paper, more specifically, a production process of a water-resistant high-strength composite vertical corrugated board. [0002] technical background [0003] At present, corrugated boxes have been widely used in the outer packaging of various products, and their demand is huge, and the demand is wide and diverse. The most common cartons on the market are single-layer cartons and double-layer cartons. Single-layer carton refers to a carton formed by two boards of single corrugated cardboard, and a layer of corrugated paper is sandwiched between the two layers of paper. Refers to the carton formed by composite cardboard. Composite cardboard means two layers of corrugated paper sandwiched between three sheets of paper. According to the type of corrugated paper, it is divided into AA type and BB type cardboard. In some products that have higher requirements for packaging strength, three-pit paper...
