Treatment Scheme for Fuzzing and Dusting of Carton Die-Cutting Machine

During die-cutting, it is often found that the edge of cartons is not smooth and fluffy, especially at some edges near the indentation line. This is because the rubber strip and indentation steel wire on the die-cutting plate exert a tension on the paper during die-cutting and pressing, and the paper is pulled off by the tension when it is not completely cut through, resulting in burrs.

Solution: First, choose different types of die-cutting knives according to the paper. The die-cutting knife includes a straight line knife and a horizontal line knife. The blade of the two lines has different heights. The lines formed by the blade are different in height, which directly affects the die-cutting quality and the service life of the die-cutting knife. In terms of avoiding die-cutting fuzzing, straight grain knife is better than horizontal grain knife; In terms of service life, the short blade is better than the high blade. When die-cutting coated cardboard, the straight-line high blade should be selected, and the blade is required to be grinded. It is not necessary to use the concave-convex one-time molding process, otherwise too much pressure will have a great impact on die-cutting; When processing ordinary paperboard, it is advisable to select a short blade, and determine the grain of the blade according to the quality of the paper fiber. www.chinacartonmachine.com

Cause of the problem: The reason for the low precision of die-cutting is the problem of die-cutting version body, as well as the problem of printing. The error of hand-made die-cutting plate is large; The different working environment of die-cutting indentation and printing process will cause paper deformation, resulting in inaccurate position of die-cutting indentation. Especially after polishing and laminating, the paper deformation is serious, affecting the die-cutting accuracy.

Solution: Select the die-cutting plate making process to improve the accuracy of die-cutting plate. The die-cutting indentation and printing process should be carried out in the same working environment or the same working environment (i.e. the same temperature, relative humidity, etc.); The paper after glazing and lamination shall be pre-processed for die-cutting to minimize the impact of paper deformation on die-cutting accuracy.
