Phase insulation perforating machine

Technical Field

Specifically, when the blanking device performs blanking, the traction device can pause traction, and after each blanking of one sheet, the traction device can re-traction the polyester film at a fixed speed and with a fixed strength, so that the blanking device can stagger the position just after blanking and perform next blanking, and the operation is repeated in this way, thereby realizing the automatic assembly line blanking production of the interphase insulation sheets.

It is known that there is a relationship between the overall friction experienced by a typical film web and the web diameter, and as the web diameter decreases, not only will the rolling friction between the films decrease, but as the weight decreases, the friction between the film web and the support frame also decreases, and therefore the maximum traction required to pull the film web for unreeling also gradually decreases. However, after each punching is completed, the traction device can re-drag at the same speed and the same torque force again in a short time, and then the traction device is immediately suspended, so that the comprehensive friction force suffered by the film coiled material can be gradually reduced along with the consumption of the polyester film, the traction of the film coiled material by the traction device becomes unstable, even the situation that the film is broken or excessively pulled by the instant traction force of the traction roller easily occurs, the punching efficiency of the punching machine is influenced, and the yield of the interphase insulation thin sheet is also influenced.
