CN102529175B - One-step folding forming method for honeycomb paper - Google Patents

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

The honeycomb paper once folding process to form

Technical field

The invention belongs to the packaging paper product technical field, be specifically related to a kind of honeycomb paper once folding process to form.

Background technology

The processing method of existing honeycomb paper core adopts mostly that the multilayer body paper is bonding cuts or cut bonding forming process, its basic principle is to adopt two volumes (layer) or the body paper more than two volumes to cut or cut multiple working procedure such as bonding through bonding simultaneously to process, it is characterized in that honeycomb paper core is combined by the single paper slip of quantity greater than several separation of l, mainly be cut-out, separation, bonding combination, coating process through at least twice, just roll web is cut off, be separated into single paper or paper slip, again with single paper or the combination of paper slip bonding.This method paper supply adopts a few volume body paper paper supply simultaneously, operation is many in the process, process route long, used plant equipment is many, make operating efficiency lower, product quality is not high, raw materials consumption is big, and is difficult to realize the compound of the MULTILAYER COMPOSITE of honeycomb cardboard or honeycomb cardboard and corrugated board from technology, because speed of production is very low, be difficult to break through ten meters high pointes of per minute, be difficult to realize high-speed uninterrupted continuous rolling continuous productive process.

Summary of the invention

The purpose of this invention is to provide and a kind ofly can simplify working process, shorten the production cycle, reduce technological equipment, reduce raw materials consumption, improve the quality of products, and can realize at a high speed the uninterruptedly once folding process to form honeycomb paper core of flowing water operation.

The objective of the invention is to be achieved through the following technical solutions:

At first body paper is pressed into continuous, three positive and negative isosceles trapezoids that the limit equates by gear, between the positive and negative isosceles trapezoid that links to each other, keep at a certain distance away and be pressed into positive V font, at interval same distance is pressed into anti-V font again, and trapezoidal have two 120 degree angles and two 60 degree angles.

Secondly at a side gluing of the inner surface of trapezoidal upper base outer surface of the forward on the positive V word left side and positive V word, at a side gluing of the inner surface of reverse trapezoidal the go to the bottom outer surface and the anti-V word on the anti-V-shape left side.

Join by the trapezoidal upper base outer surface of the forward on machinery the upper base outer surface that the forward on the positive V word left side is trapezoidal and the anti-V-shape left side then, positive V word inner surface joins, under the effect of adhesive, the part of joining can bond together, form hexagon, because the existence of V font, thereby two bottom surfaces can become easy when joining; Repeat turnover afterwards again, form cellular refill, and it is adhered stubbornly the adhesive oven dry.

At last with machine with above-mentioned cellular refill transverse cuts, can obtain the honeycomb paper core of final finished.

Beneficial effect of the present invention:

1. raw material adopts individual (layer) continuously to supply with, from start to finish paper do not cut open, not itemize, do not cut off, be connected to become an integral body all the time, the honeycomb paper slip also all the time from connection from, can work continuously.

2. do not have leftover pieces in the production process, improved utilization rate of raw materials greatly.

3. simplify original technology, reduced mechanized equipment, changed the existing process forming method of honeycomb paper core, improved speed of production.

4. easily realize the purpose of Fast transforms description, enlarge range of product size.

5. perfect part operation, the dimensional accuracy and the shape degree of accuracy that have effectively improved honeycomb paper core have improved product quality.

The specific embodiment

The present invention is described further below in conjunction with embodiment, but the scope of protection of present invention is not limited to the scope that embodiment expresses.Except as otherwise noted, embodiment mid-score and percentage all are with dry weight basis.

Present embodiment comprises technical process such as die mould, gluing, folding, oven dry, cutting, below in conjunction with Figure of description present embodiment is elaborated:

1, at first body paper is pressed into continuous, three positive and negative isosceles trapezoids that the limit equates by gear, and keeps at a certain distance away and be pressed into positive V font, same distance is pressed into anti-V font at interval again, and trapezoidal have two 120 degree angles and two 60 degree angles, referring to Fig. 1;

2, then at a side gluing of the inner surface of trapezoidal upper base outer surface of the forward on the positive V word left side and positive V word, at a side gluing of the inner surface of reverse trapezoidal the go to the bottom outer surface and the anti-V word on the anti-V-shape left side;

3, then join by the trapezoidal upper base outer surface of the forward on machinery the upper base outer surface that the forward on the positive V word left side is trapezoidal and the anti-V-shape left side, positive V word inner surface joins, under the effect of adhesive, the part of joining can bond together, thereby form hexagon referring to Fig. 2, because the existence of V font, thereby two bottom surfaces can become easy when joining.Repeat turnover afterwards again, form cellular refill (semi-finished product), and it is adhered stubbornly its oven dry (adhesive).

4, at last with machine with above-mentioned half-finished refill transverse cuts, can obtain the honeycomb paper core of final finished, referring to Fig. 3.
