250KW GUGAO PP Pet Strap Extrusion Machine

PET Polyerster Plastic Strap Production Line Band Packaging Belt Extruding Machine

PRODUCT DESCRIPTION

PET Strap Production Line Machine List

Application & features of Plastic Strapping

1. The conveyor width can be easily adjusted without the use of any tool, which can be quickly changed to the required size. Uniquely designed pull film part can be widely applicable to different types of shrink film.

2. Vertical sealing designed, sealing action is stable to provide excellent stability and durability.

3. It can reduce the sealing line folded to get a perfect sealing and cutting effect.

4. It can be equipped with automatic feeding system.

5. With horizontal and vertical two groups of electric eyes the machine can adapt to different thickness of the products.

6. It is easier to replace the product sizes.

7. It can use the shrink film of different brands.

8. It can be equipped with extra contact device and pack smaller products.

9. Relative to the traditional machine, vertical sealing machine has a major breakthrough that sealing path can be automatically adjusted according to the thickness of the product, greatly improving the production efficiency. The fastest speed is up to 40 packs per minute. For packaging those higher or lower products, it can even highlight the advantages. It can bring more satisfying effect of packaging to the user.

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.
