PET / PP strapping Production line(Heavy model)
|PET/PP||Φ75||9-19||2||PP100 / PET150|
PET or PP straps can be produced with the same technology. It takes a few minutes to change line set-up from one to the other. Heavy duty equipment can be used for four, six and eight straps production.
● Raw material process and extrusion system
1.High performance crystallizing and drying system.
2.Production can use 100% recycled material to obtain a high add value strapping band.
3.Special designed PET screw, select of single or twin screw extruder.
● Continuous back-flush screen changer operating technology (Europe technology)
1.100% full automatic self-cleaning screen changer;
2.Double column 4 screen cavities;
3.PLC control， change screen without production interrupted., not influence the production quality.
● Special designed hot air stretching oven
1.Configured with heating unit and automatic temperature control system;
2.High performance heat insulating layer;
3.Better on strip stretching and heating, rapid heating, complete strip orientation stretching.
● Embossing machine
2.Customization designed embossing roll patter available;
3.Configured with synchronous control system, adjust embossing roll vertical position and embossing strength accurately.
● Heating oven for sizing
1.Special designed technology, make sure the strip forming rapidly;
2.Prevent the strip from un-orientation after orientation, eliminate internal stress;
3.Make sure the quality of strip accuracy and quality.
● Strapping accumulator unit
1.Strap length and the winding tension can be controlled according to strap wind speed;
2.Two times completely cooling strapping;
3.Reduce strapping winding camber.
● Servo control winder (Single position and double position optional)
1.PLC control system, automatically adjust winding tension. Winding range from 5mm to 32mm;
2.Servo motor controls winder displacement width and distance. Reduce the strap bending;
3.Make sure the strap is fit for automatic packaging equipment.
