Description

Technical Field

[0001] The utility model relates to the technical field of corrugated cardboards, in particular to a creasing machine for corrugated cardboards. Background Art

[0002] Corrugated cardboard is a material made by compounding face paper and corrugated core paper through a molding process. Corrugated core paper is a paper with a wavy structure made of pulp. This wavy structure can increase hardness and strength. Face paper is a paper with a smooth surface, which is usually used to cover the corrugated core paper to play a protective and aesthetic role. Corrugated cardboard is usually used in the packaging, transportation and storage industries, especially in the packaging of fragile items such as electronic products, film products, and glass products. The protective function of corrugated cardboard is particularly important. In the process of making packaging boxes, the corrugated cardboard needs to be folded in half. Since the corrugated cardboard is relatively hard, it needs to be indented by a creasing machine before folding it in half; however, the creasing machine currently used needs to push the corrugated cardboard to move when it is necessary to indent different positions of the corrugated cardboard. However, during the movement of the corrugated cardboard, there is no limiting structure, which makes the indentation mechanism easy to offset when indenting the cardboard, thereby affecting the quality of the corrugated cardboard indentation.
