Technique for processing high bearing corrugated board

Abstract

The invention relates to a producing process for corrugated board, especially a producing process for high-loading corrugated board. A producing process that low-weight corrugated stock paper is used to produce high-loading corrugated board is provided. The process comprises feeding at least a corrugated stock paper, feeding an internal stock, corresponding to number of corrugated stock paper, feeding at least a corrugated stock paper strip with the same width of box height, adjusting and determining the position of corrugated stock paper strip to corrugated stock paper, spraying glue for each corrugated stock paper strip, preparing two-surface paper by sticking and pressing of corrugated stock paper and corrugated stock paper strip and sticking internal surface, coating glue for two-surface paper in second time, preparing paper board by sticking surface, drying, cutting in vertical direction, cutting in horizontal direction and finishing product. Because several layer of corrugated paper is added at the height position of paper box the problem that the cost of package box is against various loading quality indexes of paper box is solved. Stock is saved and cost is decreased. Various physical indexes such as loading, ring loading and edge loading so on is improved and the demand for product packaging is satisfied at a larger extent.

Description

technical field [0001] The invention relates to a production process of an automatic production line for corrugated bottom boards, in particular to a production process for producing high pressure-bearing corrugated boards from low-gram-weight corrugated raw material paper. Background technique [0002] At present, packaging cartons are the most widely used products in the packaging industry. The production of corrugated cardboard used in my country is made of corrugated paper that is processed into waves by corrugating rollers. In order to improve the value of packaging cartons, people have been researching and Improve, reduce cost, increase strength, facilitate production, improve the efficiency of automatic production, so that it can be produced on the automatic production line of multi-layer corrugated cardboard forming machine with a high degree of automation. [0003] On the corrugated cardboard automatic line, the multi-layer cardboard is formed into a corrugated type ...

Problems solved by technology

However, in the prior art, the method of improving the strength of the packaging carton is to increase the cardboard and grammage of the production carton, that is, to increase the quality of the raw material red paper, or to increase the number of layers of laminated corrugated cardboard as a whole. The current production lines in the country adopt these two methods. If these measures are not taken, the packaging cartons will not be able to achieve various physical indicators such as the pressure of the carton. The physical indicators of the carton mainly refer to the physics at the height of the carton body, while the carton indicators Failure to meet the standard means that the quality of the packaging carton is poor, which is a relatively common phenomenon
