性。 1. The whole machine is controlled by AC servo system. The winding  tension and pressure are constant and controllable. The winding diameter  of the core can reach 150 mm. 2. The machine is controlled by PLC and touch screen. It has the functions  of capacity calculation, parameter storage and parameter reading to  realize the humanized operation. 3. Material disc mechanism adopts double guide rods and precision screw  rods to ensure the parallel movement of material disc and base surface;  Material fifilm adopts double tightening combination mechanism to locate  and tighten the positioning surface and move back after tightening,  effffectively ensuring the stability of material end surface smoothness and  staggered edge; 4. Metallized fifilm material axis unwinding has translation follow-up  flflattening roller mechanism to effffectively prevent fifilm material wrinkling;  material tray movement adopts double-column guidance to improve  movement accuracy. 5. The outer needle coiling sleeve has anti-skid function, which avoids the  powder produced by skidding friction with the mandrel and affffects the  capacitance performance. 6. 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. 7. Digital control mode can be selected to improve accuracy and convenience when adjusting the scope of specifications.
