Plastic PET PP Strap Extrusion Line / Plastic Manufacturing Machine For PET PP Package Belt
Qingdao Wings Plastic Technology Co.,Ltd is the professional manufacturer of PET PP strap extrusion line. We could meet high quality strap production and high capacity request from customers.
Character :
It use single screw extruder system
For PET strap production, It use 100% recycling material
Measurement pump ensure constant and stable production
Two pull four station filter can efficiently eliminate impurity
Large hauling force stretch device and insulation oven
PET and PP strap making machinery introduction:
Pre crystallization drying unit
As PET is easy to absorb moisture in the air, it must be fully dried. At the same time, in order to prevent bonding during drying, crystallization equipment needs to be configured
PP strap not need it.
Single Screw Extruder
Always PET two straps extrusion needs 90/30 single screw extruder.
PP two straps extrusion needs 75/30 single screw extruder.
Special design screw structurer could extrude PET PP materials smoothl,it does not create excessive shear molecular structure, and ensures the strength of the packing belt
Filter, Melt Pumb, Exrusion Die Unit
It is controlled by PLC pressure closed loop control system. The pressure sensor will transmit signals, and PLC is used to control the speed of melt pump and extruder, so as to stabilize the extrusion of PET or PP materials
Water tank with first haul off rollers
PET is Length 4000mm, PP 2000mm.
It is stainless steel materials.
The water is heated by water tank heating unit
The haul off rollers is five rollers, working to take PET or PP strap materials out of water tank
The stretching oven
The oven is heated by electric power. Heating air is spread evenly by fans.
In the oven, the PET and PP strap will be stretched first time.
Stretching rollers.
This device is working for PET strap second time stretching.
PP strap not need stretching.
Embossing Roller
This 38Crmoal materials, high surface hardness rollers do embossing
Annealing oven and cooling tank
As PET and PP materials has high deformation prestress after stretching. It has to do annealing and water cooling to fix the size.
Three rollers puller
It is working to take the materials out of annealing oven and cooling tank before winders
Automatic winder
The winder could be designed into servo motor unit, inverter motor unit and torque motor according PET or PP materials and with
