MDO Film Production Line
SupereX film orientation production Line is Jinming's high-intellectualized and high-performance series with features of high-output, high-automatization and superior thickness deviation, etc.. Besides, SupereX has a good adaptability of resins, which meets customers' needs on high quality and high output.
The MDO stretching unit is composed of a group of preheating rollers, a group of S-shaped stretching rollers, a group of shaping rollers and a group of cooling rollers. For each roller, there is independent temperature control and independent drive control. The entrance is equipped with a tension sensor to realize tension closed loop control.
The winding adopts a modular design and is integrated of a variety of winding functions, which can be used to the wind the films made of different materials. The winding shafts of 3 inch and 6-inch are both available. The winding shaft can be pre-accelerated to minimize tension fluctuations and ensure the high quality winding. Its functions include automatic film cutting, automatic roll change, automatic unloading, automatic length counting and automatic taper tension control. The automatic taper tension control system can feedback and realize automatic tracking according to the surface tension of the film to improve the flatness of the winding. It will help to reduce the labor intensity of labor, reduce the waste of manual roll change, improve the efficiency, and enhance safety performance as well.
The whole machine is designed with modules. The unwinding machine, stretching system, pull-off system, and winding system are all independently controlled and driven by German Siemens PLC controller and Siemens inverter.
