Description

Technical Field

[0001] The utility model relates to the technical field of carton processing, in particular to a carton folding 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. The paper (color, feel) produced by different manufacturers is also different. Different types of cartons need to be indented and creased before production. Especially in the forming process of corrugated boxes, the folded part must be indented first before the carton can be successfully made. Therefore, a creased mechanism will be used. However, existing carton creasers all use indentation plates or indentation wheels for indentation. After indentation, it is usually necessary to manually fold the cardboard, which wastes manpower and leads to low creased efficiency. Therefore, a carton creased mechanism is proposed.
