110mm Single Screw PET Strap Extrusion Line With PLC Control And
Automatic Winder
PRODUCT DESCRIPTION
PET strap production line is used to produce mechanical or manual
bands with 100% PP recycled as materials, This kind of band is widely used in the packing of kinds of fields
such as mines, general merchandise, weaving, electrical equipment,
apparatus, architecture, medicine, etc.
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
Advantages:
1. This line is specially designed for the production of PET
Straps. It can produce 2,4,6,8,10,12 Straps at the same time that
saves energy by 20%-30%;
2. Both the Shaping Water Tank and Calibrating Tank are made of
stainless steel that the tanks are long-lived;
3. PLC Controller by touching keys with alternative languages,
which is safe and easy to operate that keeps good status of all
part and ensures the stable performance of whole line and
continuous production of PET Straps.

PET and PP strap making machine 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.
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 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.
This device is working for PET strap second time stretching.
PP strap not need stretching.
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.
It is working to take the materials out of annealing oven and
cooling tank before winders
The winder could be designed into servo motor unit, inverter motor
unit and torque motor according PET or PP materials.
The unique back tooth shaft is used to make the packing belts
neatly arranged without overlapping and no horn shape, so that the
packing belts maintain a good straightness, which is more suitable
for the use of automatic packing machines, and ensures that the
automatic equipment conveyor belts are in place. Do not drop the
belt.
