Honeycomb paper core innovation structure and core paper gluing technique

Abstract

The present invention relates to a honeycomb paper core innovation structure and a core paper gluing technique. The structure is characterized by consisting of honeycomb core layers I and honeycomb core layers II which are made of different materials; the honeycomb core layers II are staggered; and the shape of the honeycomb core layers II in honeycomb cells is determined by the adhesion size. The honeycomb core paper adhesion technique can be implemented in two ways. According to the adhesion technique in the first way, front and reverse surfaces of the two rolls of honeycomb core paper II are glued in a staggered manner, and the two rolls of honeycomb core paper I are respectively glued and compounded with the two rolls of honeycomb core paper II through an octagonal drum to obtain core paper. According to the adhesion technique in the second way, the first layer of the honeycomb core paper I is not glued, after being glued respectively in a staggered manner, the following three honeycomb core layers are respectively adhered to the previous honeycomb core layers, and then the last layer is glued in a staggered manner, and is glued to the previous cutting unit after being cut off by a cutter so as to form continuous core paper. Compared with the original process, the honeycomb paper core gluing technique provided by the present invention is seldom changed, and has the advantages of convenience in design, reasonable structure, high strength, easiness in material selection, simplicity, low cost and the like.

Problems solved by technology

Therefore, the basis weight of the paper core is generally between 120g / m2-180g / m2. In addition, due to the limitation of the process conditions, the pore size of the honeycomb cell cannot be too small, generally greater than 6mm. Various reasons limit the compressive strength of the honeycomb paperboard.

Whether it is possible to improve the existing honeycomb paperboard structure, through low basis weight, large aperture honeycomb paper core or different basis combination to achieve high basis weight, small aperture honeycomb paper core compressive strength requirements, many literatures have tried, such as adding Inserting blocks or strips to improve the strength of honeycomb paperboard, but this method is complicated in process and low in production efficiency; and the compressive strength of honeycomb paperboard can be improved by combining different quantitative intervals of core paper, but the transformation of the production line is more complicated, and at the same time, high quantitative core paper has tension.
