Corrugated board production method and apparatus thereof

Abstract

The invention discloses a corrugated board production method and an apparatus thereof. The production method comprises the following steps: coating corrugated paper with a heated adhesive at a low temperature, and bonding the coated corrugated paper with a cardboard to obtain a one-sided corrugated board. Traditional technologies and apparatuses for producing corrugated paper through a starch adhesive are subverted, a hot adhesive is applied in production of the corrugated paper, and the hot adhesive obtained after heating the adhesive can effectively bond paper with the corrugated paper without heating the paper, so the corrugated board can be produced at a low temperature, and heating is carried out in adhesive application and adhesive storage processes without heating a corrugation roller, thereby the energy consumption is greatly reduced.

Description

technical field [0001] The invention relates to a corrugated cardboard production technology, in particular to a corrugated cardboard production method and device. Background technique [0002] Corrugated cardboard is a multi-layer bonded body, also known as corrugated cardboard. It is made of at least one layer of corrugated paper and a layer of cardboard (also called cardboard), which has good elasticity and extensibility. It is mainly used in the manufacture of cartons, the sandwich of cartons and other packaging materials for fragile goods. Corrugated cardboard is made of raw cardboard similar to yellow cardboard by beating straw pulp and waste paper by local methods, and then machined to make it rolled into corrugated shapes, and then glued on the surface with adhesive and boxboard paper. [0003] At present, most of the adhesives used for gluing corrugated paper are starch adhesives. After compounding, the flatness of the cardboard is low. After the cardboard is used...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the adhesives used for gluing corrugated paper are starch adhesives. After compounding, the flatness of the cardboard is low. After the cardboard is used for a long time, the cardboard layer on the surface is easy to crack from the corrugated paper layer, and degumming occurs. , its adhesive strength needs to be improved

In addition, the upper and lower transmission methods used in the prior art need to occupy a large amount of installation space. The lower surface of the corrugated paper is used as the glue surface, and the phenomenon of glue dripping is serious.

[0004] The use of starch adhesive requires the use of a large amount of heat source in the production process to heat the starch adhesive and paper to achieve the bonding effect. At the same time, the transportation channel after the production of corrugated paper, because the corrugated paper uses water-based starch, humidity It is relatively large and needs to be heated and dried. Usually, a heating channel is used for transmission. The above heating temperature needs to be above 100°C. Generally, it is necessary to burn a boiler to achieve long-term high temperature, which will consume a lot of coal and electricity energy.
