1.Synchronized multi-functional composite winding of optical film,metallized fifilm and foil capacitor. 2. The needle-type cutting mechanism is used to realize the synchronous  winding of aluminum foil, metal fifilm and optical fifilm, and the function of  folding aluminum foil can be matched. 3. Using Siemens PLC and touch screen control, with capacity calculation,  parameter storage, parameter reading function, to achieve humanized  operation. 4. The whole machine is controlled by Panasonic AC servo system, and the  winding tension is controlled by Japanese precision low friction cylinder,  which can improve the accuracy and compensate the tension when the  speed is lowered. 5. Precision screw rod is used to effffectively reduce the adjustment  clearance, increase the adjustable locking device, adjustable clearance  and prevent the displacement of the staggered edge. 6. The frame of the machine is of integral structure, which can change the  lack of strength of multiple assemblies, effffectively improve the accuracy  and durability, and greatly reduce the mechanical vibration. 7. It has the function of secondary heat seal. The time and pressure of  primary heat seal and secondary heat seal can be set separately,which is convenient for the later process.
