Description

Technical Field

[0001] The utility model relates to the technical field of carton printing, in particular to a carton printing and forming production line with a printing part provided with a large belt transmission mechanism. Background Art

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Commonly used cartons are three-layer and five-layer, and seven-layer is less used. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The lining and face paper are tea board paper and kraft paper, and the core paper is corrugated paper. The color and feel of various papers are different, and the paper (color, feel) produced by different manufacturers is also different. Cartons need to be printed during the production process, and generally the printing is transported through a special conveying mechanism.
