Film slitting is very important in film production, especially high strength film. When the slitting blade is good, it can provide smooth winding and reduce wrinkles.
Influence of blade on film cutting
Because of the friction between the film and the blade, the film elongates along the slitting edge. In severe cases, the edge of the film looks like the edge of a stamp. In the winding process, if this situation continues to occur, the film will accumulate at the edge of the roll, resulting in a speed difference between the edge and the center of the roll. There are other problems such as production stoppage during rewinding and printing.
Poor slitting quality results in plastic powder adhering to the film and cannot be used in purification workshops or printing. In addition, poor blades need to be replaced more frequently, which increases the operational risk of replacing blades.
Blade has the following several kinds: General razor blade, standard industrial blade, tin plated industrial blade, special coating blade. The blade thickness is mainly 200 μ M. The slicing quality depends on the friction between the blade and the film. The smoother the blade, the better the slitting. There is a thin coating on the blade. The coating is applied on the grinding edge. The coating is very hard and plays a protective role when cutting.
Excellent blade has the following characteristics: 1. Safe and long-life blade means that you can rarely change the blade, there is always a safety risk.
2. Flat film roll: (1) flat winding; (2) eliminating wrinkles; (3) increasing printing and compound production.
3. Eliminate dust (1) solve the problem of cleaning the room; (2) increase printing and compound production; (3) reduce dust removal process and maintenance.
