Pet Polyester Strapping Band Making Machine / PP Pet Strap Extrusion Production Line

PET Polyester Strapping Band Making Machine / PP PET Strap Extrusion Production Line

Basic Information:
1. Special design of the screw extrusion technology can be choosing as per customer needs.
2.  Can process 100% recycled PP/PET bottle flakes or pellets.
3.  Plasticization and stable extrusion can with PLC automatic control for the full line.
4.  According different requirements, changing materials for make strap have better and special function.  For 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 back flushing.
6.  Number of strap:1,2,4,6,Width: 5mm-22mm,Thickness: 0.5mm-1.5mm
7.  Workers: 2 -3 workers per shift, 12 hours/shift.

PET strap, also known as plastic steel band, which is used in place of steel on the world of a new environmentally friendly packaging materials, the development of new materials in recent years the cost of success and a substantial decline, have been widely used in the steel industry, chemical fiber industry, aluminum ingots, paper, brick kiln industry, screw industry, tobacco industry, electronics, textiles and wood, etc.; is replaced by a new high-strength steel strapping, is the world's most widely used for steel products.

PET and PP strap making machinery introduction:

1, The raw material will be dried by the dehumidifier, and the below 40 dew point make the material humidity less than 40PPM, and condensation polymerization(this is for PET straping line);
2, The conveyor of the raw is in a enclosed and circular mode, and without contacting with the air, in order to made perfect effect of drying;
3, Special designed extruder screw for PP/PET production, bear the better performance of material separating and mixing.  Automatic material feeding provide the smooth environment for the PP/PET strap production.
4, Special designed extrusion die & mould;  And the improved screen changer realize non-stop screen changing, and without material leakage;  Wedo also equitp the melting pump to ensure the packing strap material out more everage.
5, Water tank cooling the PET strap band.  The steady water temperature enhance of the molecular tension strength(better equip water chiller);
6, Heating cabinet is used for thermal annealing, relief the band distortion after long-time storage;
7, Double-station automatic winder, easy operation;  We provide our worldwide customer the turn-key project.  We will assist our customer from the installation to the final production of this line.
 

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
