SED-170SZB-A is a bottom-feed three-servo pillow (horizontal flow) packaging machine. Three independent servo drives (film-feed servo + product-feed servo + end-seal/cut servo) provide best-in-class positioning accuracy.
Funcionamiento
Three-servo horizontal flow wrapper: Servo 1 unwinds the film up to 440 mm wide; the film passes through the forming collar to wrap the product. Color-mark photoelectric sensor (Shanghai Yatai GDJ-211 G) tracks pre-printed registration marks. Servo 2 drives the product infeed conveyor at auto-positioned speed. Center seal: heated rolls and traction rollers create the longitudinal fin seal. End-seal servo 3 drives the cross-seal jaws to seal and cut each package; rotary knife cuts the seal. Completed packages discharge from the machine end.
