Reasons for label breakage of heat shrinkable film label labeling machine

The reason for the label breakage of the heat shrinkable film label labeling machine. Release time: 2019-04-04 1. The problem of the label itself. The cut of the bottom paper of the label is one of the reasons for the label break. An obvious phenomenon of this problem is that the fracture is very large. Neatly, when you observe carefully, you can find that the bottom paper of the label has obvious cut marks, as shown in the figure below. This situation is caused by the heavy pressure of the cutter when making the label, and the label needs to be redone. The wrong material of the bottom paper of the label will also cause the label to be broken. The standard labeling machine labels are all glassine, and the bottom paper of the coated paper is due to the insufficient strength of the bottom paper. In addition to the problem of the label itself, the label breakage is mainly concentrated on the stripping plate. 　　 One of the main reasons is that the stripping plate is too sharp. The stripping plate is made by sheet metal processing, and the main knife edge It is caused by excessive cutting and milling. The main treatment method is to manually polish the knife edge to make the transition at the knife edge smoother. Then there is a broken mark caused by the knife edge due to the crooked assembly of the stripping plate. The edge of the knife is not level, which causes the label to be unevenly cut when passing the knife edge, and it will also cause the label to be broken. 3. The problem of the tensioning mechanism is in the entire header. The purpose of the tensioning mechanism is to ensure that the label is It can be separated from the stripping plate relatively uniformly and stably. For this purpose, the tension of the label needs to ensure a certain strength. When the force is too large, it will also cause the label to break. Strength, the elasticity of the brake lever is resolved. Heat shrinkable film label, heat shrinkable film label manufacturer Previous: Features of ops heat shrinkable film
