3/5layer stretch hood blown film solution

● Wholeline control PLC: Siemens S7-1500 series;

● Online automatic airring& thickness measurement& control, imported  KUNDIG thickness measurement& control system;

● The entire line uses Servo motors, the extruder uses Servo motors, all nip motors use  German  geared  motors, the  gearbox  uses  German  gearbox, and  the   nip  drive  uses SIEMENS Cu320;

● Blown film DIE: Unique technology for blown film processing;

● Fully automatic central& surface winding machine, automatic rollchanging/automatic winding/automatic unloading;

● The winding is controlled based on the taper tension of the coil diameter to ensure smooth winding, especially for large diameter winding.

● After the diameter of the membrane coil increases, the tension of the membrane coil is ensured;

● Tension  control: E+L  imported tension sensor from Germany, which ensures stable tension and small fluctuations, ensuring that the film does not stretch or deform;

● The central winding and gap winding modes can be freely switched for easy operation.

● Surface winding driven by Siemens servo motor

● Central winding driven by Siemens servo motor

● The automatic roll changing mode can be divided into two options:

● Length roll changing and diameter roll changing, After setting the length or diameter, the rollcan be automaticallychanged with one click operation;

● The center drive is driven by a German geared motor, with stable output; Hydraulic unwinding, safe and stable, can unload film at any position, with flexibleoperation;

● The design of the unloading hydraulic manipulator is safe and stable, with no haft protection;

● Intelligent protection function for changing the coil, predicting and preventing injuriescaused by operational errors.
