PET Strap PLC Control System from

Polyester PET Strap Making Machine Belt Package Production Line GUGAO Motor

PRODUCT DESCRIPTION

PET Strap Production Line Machine List

Features:
1. PET plastic steel strip is a kind of packaging material with good tensile strength and excellent fusion performance.
2. It has a very good tightening and holding capacity, and does not relax for a long time after packing, so as to ensure that the goods have excellent impact resistance in long-distance transportation.
3. Good economic benefits. The density of PET plastic steel strip is only 1 / 6 of that of steel strip, and the price per unit length is relatively low. The length of one ton of plastic steel strip is equivalent to that of six tons of steel strip, and the cost per meter is lower than that of steel strip.
4. It can be packed directly with PET plastic steel belt, and the goods will not be damaged or corroded.
5. Good flexibility, convenient and safe operation. PET plastic steel belt has no sharp edge of steel belt, which will not scratch the package or hurt your hands. No special tools are needed when cutting. Even if the binding is tighter, people will not be hurt when cutting.
6. Excellent weather resistance, between - 50 ºC - 100 ºC, keep good stability.
7. Beautiful appearance, environmental protection, recyclable.

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.

• 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.

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.
