65mm Screw Plastic Strap Making Machine Pet Strap Production Line PLC Control
PRODUCT DESCRIPTION
PP strap production line is used to produce mechanical or manual bands with 100% PP recycled granules as materials, if raw materials, it will be better. 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 PP Straps. It can produce 2 PP 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 PP Straps.

PET and PP strap making machine introduction
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
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
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
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.
