The Chain feeder printer slotter diecutter manufacturer tells you that during the die-cutting process of the cigarette label, due to various reasons, filamentous, powdery or serrated paper scraps, color ink powder or white spots remain at the incision of the steel knife on the cigarette label. Commonly referred to in the industry as die-cut flash. Chain feeder printer slotter diecutter manufacturers tell you that the main reasons for die-cutting burrs are as follows:
1. The die-cutting steel knife is improperly selected or the quality of the steel knife itself is defective, and the edge of the knife edge is curled and defective, resulting in obvious burrs on the edge of the die-cutting product.
2. The overall pressure is too high during plate loading, and the edge of the steel knife is crushed.
3. There is no partial decompression after the local knife change, resulting in overpressure of the new knife and damage to the blade.
4. Due to the particularity of cigarette label products, long-term mass production is required. During the production process, the steel knife will be naturally worn to varying degrees. At this time, the product is forced to be crushed instead of being cut through by the blade. In this case, it is easy to produce burrs.
5. The pressure is not enough, the paper is not cut through, but torn when removing the waste paper edge.
6. The bottom steel plate of the moving platform will produce kerfs after long-term use. The rough kerfs can easily damage the steel knives and cause burrs.
7. The hardness and height of the rubber strip on the knife side are not suitable or the sticking distance is unreasonable. The manufacturer of Chain feeder printer slotter diecutter tells you that the hardness is too low, the height is not enough, or the sticking distance is too far, and the paper cannot be effectively pressed; the hardness, height, or sticking distance of the adhesive strip is too large, and the paper is forcibly pulled by the adhesive strip before the knife is completely cut. Breaks will cause burrs.
8. When the distance between the knife on the die and the steel wire is too small, the paper will be pulled between the rubber strip and the bottom film of the indentation, and it will also cause paper burrs.
9. The die-cutting suitability of the paper itself will also lead to the appearance of burrs to a certain extent. For example, gold-silver composite cardboard is prone to filamentary burrs, while white cardboard glass cardboard is more likely to have powdery burrs; paper with shorter fibers Low cost but prone to burrs, paper with longer fibers is relatively rare, but more expensive.
10. At this stage, most of the base molds of the flat die-cutting plate are 18mm thick multi-layer composite glue boards. The Chain feeder printer slotter diecutter manufacturer tells you that theoretically, the texture, uniformity and deformation resistance of the board will also indirectly cause burrs through the influence of the angle when the die-cutting steel knife is cut.
Cause: The die-cutting knife is not sharp enough, or the rebound rubber strips on both sides of the knife are not hard enough. When the blade cuts into the paper, the paper cannot be fixed, so that the blade cannot be cut evenly, and paper fuzz is generated. Solution: The manufacturer of Chain feeder printer slotter diecutter tells you that if the new blade is blunt, in addition to the possible reasons of the equipment itself, there may also be an improper operating pressure setting. Too much pressure will shorten the life of the blade.
