The early start of pressure discharge is also an important reason for the loose version. After die cutting, when the moving platform descends, although the paper has been bounced off the cutting line by the elastic rubber strip (sponge), the elastic rubber strip (sponge) is generally 2-3 millimeters higher than the cutting line. If the paper teeth start to move at this time, the elastic rubber strip (sponge) will still press the paper onto the die cutting bottom plate, which is easy to tear the paper and cause loose plate. At this point, the connecting sleeve between the intermittent mechanism and the main chain wheel shaft should be loosened for adjustment, so that the moving platform can drop by 7-8 millimeters from the top dead center (which should be around 10-15 millimeters during corrugated paper die-cutting), and the pressing plate begins to move. If the elastic rubber strip (or sponge) on the die-cutting plate is too soft, the fully automatic die-cutting machine cannot smoothly bounce the paper, which can also cause plate scattering. At this point, elastic rubber strips (or sponges) with high hardness and good elasticity of the die-cutting machine should be selected. The quality of the printed matter being die-cut is also one of the reasons for the loose plate of the die-cutting machine. If the printed image of the fully automatic die-cutting machine has poor paper quality and short fibers, it may cause loose printing during the die-cutting process. At this point, the die-cutting machine can reduce the die-cutting speed and increase the number of connecting points appropriately. When making die-cutting plates, if the shape of the live parts is complex or there are many arranged live parts, and the die-cutting connection points are very small or few, it is easy to cause loose plates during die-cutting. At this point, the number of connecting points should be appropriately increased, and if possible, the length direction of the live parts should be consistent with the direction of paper transfer.
