PET Plastic Belt Production Line Pet Packing Tape Equipment Strap Making Machine
PRODUCT DESCRIPTION ABOUT PET STRAP MACKING MACHINE
PET strap production line Function and Advantage:
High tensile strength, limited elongation, good impact resistance, economic, convenient operation and safety. It is an ideal substitution of traditional steel strap.
Packing for paper, wood, cotton, fiber, metal, aluminum-plastic profile products and various pallets.
Features pet strap production line:
1, Special twin screw extrusion technology and single screw extrusion technology, can be choose as per customer needs
2, Process 100% recycled PET bottle flakes( After Grace-M PET washing and recycling line)
3, Even plasticization and stable extrusion with PC automatic control for the full line
4, As per different requirements, changing A coating materials for make strap have better and special function. Foe example, the strap for packing cotton, can be from enhancing the breaking strength and joint strength when welding strap
5, Melt filter with two pistons with air venting design and backflusing
6, Number of strap: 1, 2, 4, 6

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.
