Paper web honeycomb board

Abstract

The invention discloses a paper tube honeycomb panel, which is composed of a tubular paper core, the paper core can be bonded to the panel, or the bottom plate, or between the panel and the bottom plate, and the paper core is composed of several mutually independent single structure paper tubes Composition, the paper tubes of each monomer structure are closely and orderly arranged in the same direction and superimposed, and are fixed by glue bonding at the superimposed places. Among them, the paper tube can be a cylindrical closed structure, the paper tube can be single-layer, or double-layer or multi-layer, and the cross-section of the paper tube can be circular, square or regular hexagonal, forming the individual structures of the paper core. The paper tubes are independent of each other, and their positions can be adjusted by external force to fix the shape, and the length of each paper tube can be different. Since the paper tube with a single structure is used as a single component of the honeycomb structure, the honeycomb structures are independent of each other, so that the honeycomb uniformity of the honeycomb panel can achieve a better effect and the strength of the honeycomb panel is uniform; It is also possible to make the shape of the honeycomb panel into a curved surface.

Description

technical field [0001] The invention belongs to the technical field of plate processing, in particular to a paper tube honeycomb plate. Background technique [0002] Cardboard is a board with a wide range of uses. It has the characteristics of light weight, high strength, heavy load bearing, and good shock resistance. The traditional structural cardboard is mainly corrugated cardboard and honeycomb cardboard, which are generally made by stretching. figure 1 , figure 2 The structure of the paper core of the honeycomb paperboard in the prior art is given. When making it, a number of paper strips are stacked together, and glue is applied to the mutually misplaced position 1', and the glue sticks to make the paper strips stick together. After the mutual dislocation forms a fixed phase connection, the paper core is stretched on both sides to form a honeycomb shape, and then the upper and lower ends of the honeycomb paper core are pasted with upper and lower paper to form a hone...

AI Technical Summary

Problems solved by technology

Although the corrugated cardboard and honeycomb cardboard made in this way have the advantages of light weight and high strength, there are still the following deficiencies. One is that the bonding glue at the bonding position 1' is difficult to form uniformly, resulting in stretching. The size of the honeycomb formed in the end is not easy to be uniform, which leads to poor uniformity of the strength of the cardboard; second, the thickness of the core paper and the weight per unit area of ​​the cardboard cannot be sufficiently large, which affects the increase in the strength of the cardboard; third, the edge of the corrugated core honeycomb The length cannot be sufficiently small, which affects the improvement of the strength of the cardboard; the fourth is that the total height of the core paper cannot be sufficiently high, which limits the thickness of the cardboard (usually not more than 50mm); the fifth is that the structure of the core paper is not independent and cannot be formed as required Arrangement of paper cores with different structures; Sixth, this kind of core paper can only be made into flat boards, and cannot be made into curved boards
