Multi-layer corrugated board gluing device

Abstract

The invention discloses a multi-layer corrugated board gluing device, and relates to the technical field of corrugated board processing. The multi-layer corrugated board gluing device comprises a rack, one end of the rack is rotatably provided with three groups of flat paper rolls and two groups of corrugating medium rolls, and the two groups of corrugating medium rolls are located between two adjacent corrugating forming extrusion rollers; and two groups of flattening conveying rollers are rotatably installed at the other end of the rack, two groups of corrugated forming extrusion rollers are arranged at the positions, corresponding to the two corrugated forming extrusion rollers, of the rack, and the number of each group of corrugated forming extrusion rollers is two. The two groups of flattening conveying rollers are rotatably driven, so that the flattening conveying rollers are utilized to realize the pressing function of glued flat paper and corrugated paper, the traction function of all paper tapes is also realized, and meanwhile, the swinging of an arc-shaped glue smearing plate is utilized to realize the functions of gluing and uniformly smearing the bonding surface of the flat paper, thus the gluing and compounding efficiency of the device is improved, and the gluing effect of corrugated board forming and gluing is improved.

Description

technical field [0001] The invention relates to the technical field of corrugated cardboard processing, in particular to a multilayer corrugated cardboard gluing device. Background technique [0002] Corrugated cardboard is a multi-layer bonded body, which consists of at least one layer of corrugated core paper (commonly known as pit sheet, corrugated paper, corrugated core paper, corrugated core, corrugated base paper) and a layer of cardboard (also known as boxboard, boxboard, etc.) ) composition, has high mechanical strength, can withstand collision and fall during handling, and is mainly used in the manufacture of cartons, the sandwich of cartons, and other packaging materials for fragile goods. It mainly adopts domestic straw pulp and waste paper to be beaten to make raw cardboard similar to yellow cardboard, and then it is machined and rolled into a corrugated shape, and then the surface is bonded with boxboard paper with an adhesive such as sodium silicate.

AI Technical Summary

Problems solved by technology

[0004] Since corrugated cardboard has a multi-layer structure, the structural parts of each layer need to be bonded. At this time, it is necessary to use a gluing mechanism for gluing. However, the existing gluing mechanism has a single structure, a single function, and the gluing is not uniform enough, resulting in The production efficiency of corrugated cardboard in the later stage is low and the quality is poor
