Automatic hot foil stamping and die cutting machine common problem: paper feeding is not smooth

The unsmooth paper feeding is one of the common problems of the automatic hot foil stamping and die cutting machine. There are various reasons for the paper feeding being unsmooth, mainly due to paper deformation, too smooth printed surface or other mechanical failure.

1. Paper feeding caused by paper deformation is not smooth

    Since the die-cutting process is the end of the whole printing process, the paper is easily deformed after several processes, especially after the high-temperature, high-pressure glazing film is deformed more severely. Feed paper.

2. the paper is not smooth due to the smooth surface of the printed matter

    After the glazing film is too smooth, it will cause certain difficulties in paper feeding. For the above two cases, the experienced operator will do the preparatory work before loading the paper. For example, when loading paper, add some wooden wedges or paper rolls to the paper to keep the paper flat, and pre-print it when loading paper. This problem can generally be avoided by cutting the paper edge or by appropriately lowering the speed of the die cutting machine.

3. Paper feeding difficulties caused by mechanical failure

    The suction of the Feida nozzle is not enough, the position of the plane on the paper stack is not suitable, the positioning of the rule is not accurate, and other mechanical reasons may cause slanting, double, and empty sheets during the paper feeding process. As long as the maintenance of the die-cutting machine and the adjustment of the mechanical parts are done normally, it will avoid the difficulty of paper feeding due to mechanical failure.
