Corrugated paper production mechanism, four-layer corrugated board production line and production process thereof

Abstract

The invention relates to a corrugated paper production mechanism, a four-layer corrugated paper board production line and a production process thereof. A corrugated paper production mechanism comprises a corrugated paper molding part. The corrugated paper molding part comprise a first corrugated roller, a second corrugated roller, a third corrugated roller, a fourth corrugated roller and a first glue painting mechanism, wherein the first corrugated roller and the second corrugated roller are used for molding first corrugated paper in a matched mode; the third corrugated roller and the fourth corrugated roller are used for molding second corrugated paper in a matched mode, and the first glue painting mechanism is used for painting glue on the second corrugated paper. The first corrugated roller is arranged between the fourth corrugated roller and the second corrugated roller, and the first corrugated roller and the fourth corrugated roller are matched to form a bonding passage, the bonding passage is bound by the first corrugated paper molded by the first corrugated roll and the second corrugated roller and the second corrugated paper molded by the third corrugated roller and the fourth corrugated roller. The tip a of the first corrugated paper and the tip b of the second corrugated paper are bonded in a tip-to-tip mode to form double-layer corrugated paper under the action of addendums of the first and fourth corrugated rolls separately. The corrugated paper production mechanism, the four-layer corrugated paper board production line and the production process thereof solvesthe problems that a layer of bottom paper needs to be clamped between two pieces of corrugated paper, the paper consumption is large, and the strength of the corrugated paper is low due to the fact that a tip-to-tip mode is difficult to achieve in the corrugated paper bonding process are solved.

Description

technical field [0001] The invention relates to the technical field of corrugated cardboard production equipment, in particular to a corrugated cardboard production mechanism, a four-layer corrugated cardboard production line and a production process thereof. Background technique [0002] In the prior art, when producing corrugated cardboard, the base paper is usually first pressed into corrugated paper, bonded with the base paper to form a single-sided corrugated cardboard, and then glued on the corrugated board and pasted with the face paper to form a three-layer corrugated cardboard. , Or add a set of single-sided corrugated cardboard forming equipment, and then bond to form five layers of corrugated cardboard or even seven layers. [0003] A Chinese invention patent with the authorized notification number CN102173162B, which discloses a production method and production line of pre-printed corrugated cardboard, which solves the problem that the existing corrugated cardboa...

AI Technical Summary

Problems solved by technology

[0005] One of the objectives of the present invention is to provide a corrugated paper production mechanism for the deficiencies of the prior art. By passing two sheets of corrugated paper between two corrugated rollers, the tooth tops between the two corrugated papers are facing the tooth tops. It realizes bonding the tip of two pieces of corrugated paper to the tip to form a double-layer corrugated paper, and then coats the face paper and the bottom paper on both sides of the double-layer corrugated paper to form a four-layer corrugated board, thereby overcoming the two-layer corrugated paper in the prior art. A layer of backing paper needs to be sandwiched between corrugated papers, resulting in large paper consumption and high cost, and it is difficult to realize that the tip of the two corrugated papers is facing the tip during the bonding process, resulting in the use of an extra piece of backing paper.
