Problems solved by technology

Letterpress printing is used for graphic printing of a single corrugated box. Its feature is to print graphics directly on the cut corrugated box. Therefore, the corrugated is easy to damage and the strength of the box is reduced.
Lamination is used for the compounding of single pre-printed paper and corrugated box sheets, that is, the cut single-sheet pre-printed paper and corrugated cardboard are bonded together with glue. This method is due to the fact that the glue is rich in water. , so that the water content of the corrugated box sheet increases, causing the corrugated box sheet to become soft, and it can only be shipped after drying. Therefore, the production cycle is long, which is not conducive to industrial continuous production, and the efficiency is low

Embodiment Construction

[0008] The present invention will be further described below in conjunction with accompanying drawing by embodiment:

[0009] The process steps of the production method include: web (120g / square meter-300g / square meter) pre-printing, corrugated paper rolling, bonding and drying, longitudinal cutting, cross cutting and box sheeting. The steps of web pre-printing consist of web unwinding, multi-color gravure (flexo) printing, and post-press winding. Then, the pre-printed web is fed into the corrugated board production line and laminated with the rolled corrugated paper. Dried, then longitudinally cut and crosscut into box pieces. The corrugated board production line includes four processes of corrugated paper rolling, lamination and drying, slitting, and cross-cutting. Five-layer and three-layer corrugated board production lines can be selected.

Abstract

The production process of corrugated box sheet includes th technological steps of: preprinting of rolled paper, rolling corrugated paper, adhering and stoving, longitudinal cutting and transverse cutting to form box sheet. The said technological process is superior to available process and has high production efficiency, high paper utilization, high corrugation strength and beautiful corrugated box product.

Description

technical field [0001] The invention belongs to a production method of corrugated box sheets. Background technique [0002] Before the present invention was made, the structure of the existing corrugated box sheet was mainly composed of three layers of printing surface paper, corrugated paper, and inner paper, or five layers of printing surface paper, corrugated paper, core paper, corrugated paper, and inner paper. The method of producing corrugated box sheets in China is divided into two types: direct letterpress printing and lamination of box sheets according to the surface paper of the box sheets. Letterpress printing is used for graphic printing of a single corrugated box. Its feature is to print graphics directly on the cut corrugated box. Therefore, the corrugation is easy to damage and the strength of the box is reduced. Lamination is used for the compounding of single pre-printed paper and corrugated box sheets, that is, the cut single-sheet p...
