Technical Field

[0001] The utility model relates to the technical field of carton making, in particular to a pressing device for cutting carton. Background Art

[0002] Carton making is a process that involves several steps, including cutting the carton;

[0003] The cutting of cartons is actually cutting the cardboard according to the indentation, so as to facilitate the subsequent folding of the cardboard to form a carton. Before cutting the cardboard, the cardboard needs to be pressed and fixed to avoid displacement of the cardboard during the cutting by the cutter. Generally, a pressing structure is used to fix the cardboard, specifically: an electric telescopic rod is used to drive a pressing plate to press and fix the cardboard. However, the above operation is likely to leave indentations on the cardboard, which affects the appearance of the subsequent carton.
