One-step folding forming method for honeycomb paper

Abstract

The invention discloses a one-step folding forming method for honeycomb paper. In the existing honeycomb paper core making process, the multi-layer raw paper bonding / cutting or cutting / bonding forming method is adopted, which has the problems of low work efficiency, poor product quality and large material consumption. The method comprises the following steps of: firstly, pressing raw paper by gears to form isosceles trapezoids and inverted isosceles trapezoids, which are interconnected and provided with three equal three sides; then, coating adhesives on the surfaces of the isosceles trapezoids and the surfaces of V-shaped structures; subsequently, mechanically connecting the upper bottom outer surfaces of the trapezoids on the left side of one V-shaped structure with the upper bottom outer surfaces of the trapezoids on the left side of a corresponding inverted V-shaped structure, and mechanically connecting the inner surfaces of the V-shaped structures; and finally, mechanically cutting the honeycomb paper core in the transverse direction, to obtain finished products of honeycomb paper core. The paper sheets as raw materials are continuously fed one by one and not scissored or divided or cut in the whole process, and are always connected as an integral body. The honeycomb paper is in end-to-end connection all the time. The method achieves the effect of continuous operation.

Description

technical field [0001] The invention belongs to the technical field of paper product packaging, and in particular relates to a honeycomb paper one-time folding forming method. Background technique [0002] Most of the existing honeycomb paper core processing methods adopt multi-layer base paper bonding and cutting or slitting and bonding forming method. The basic principle is to use two rolls (layers) or more of It is processed by multiple processes such as bonding. It is characterized in that the honeycomb paper core is composed of several separated single paper strips with a number greater than 1. It is mainly cut, separated, and bonded. After at least two gluing processes , That is to cut the roll paper, separate it into individual paper or paper strips, and then bond the individual paper or paper strips together. This method uses several rolls of base paper to feed paper at the same time. In the process of processing, there are many processes, long process routes, and m...

Problems solved by technology

This method uses several rolls of base paper to feed paper at the same time. In the process of processing, there are many processes, long process routes, and many mechanical equipment used, which makes the work efficiency low, the product quality is not high, the consumption of raw materials is large, and it is difficult to realize the honeycomb process from the process. For the multi-layer compounding of cardboard or the compounding of honeycomb cardboard and corrugated cardboard, due to the low production speed, it is difficult to break through the ten meters per minute mark, and it is difficult to realize high-speed uninterrupted continuous rolling flow operation
