250kg/H Brick PET Plastic Packing Belt Machine 9-32mm Strap Manufacturing
PRODUCT DESCRIPTION
Pet packing belt one out two production line equipment:
Pet belt (commonly known as plastic steel belt) is a new type of
binding belt which is currently popular in the world to replace
steel belt. It is widely used in steel, aluminum, chemical fiber,
cotton spinning, paper industry, wood industry, building materials,
metal products and other industries.

Advantages of Plastic Strapping
PET strap is recognized a new environment protective strapping
material to substitute for Steel Strap &PP Strap in the ruling
international market. They are not only the aggregation of the
intensity and the tenacity of steel strap, but also overcome the
disadvantage of the tradition packing material such as insufficient
intensity, brittle and so on. At present, they have been applied in
wood, steel and so on.
Adopts advanced dehumidify dryer system. It makes sure the material
humidity at 80PPM at 50PPM dew point. Meanwhile, it compact
material and increase the viscidity.
Adopts closed cycle transport system after dryer to avoid contact
with outside air and make sure the material drying continuously.
Extruder adopts special screw for PET. The screw has unique
separate and mix property to make sure uniform plasticizing. The
screw is suitable for recycled PET bottle flakes, PET mixture and
original PET material. And the extruder adopts ration forced
feeding to make sure the stable extruding. It makes sure the
product uniform.
Produce different model product at one die and mould, adopting
hydraulic screen exchanger without material leak.
Static cooling roller replaces the water cooling tank. The roller
will cool the strap at the constant temperature. It improves the
product's stretch intensity.
The strap after formed will be warm and anneal treated to wipe off
the part stress remained after stretch. It makes molecule tropism
be steady to avoid strap distortion caused by storage.
The winder adopts double work position and auto-meter. It is easy
operation and convenient coil change.
Centralized electrical control, PLC self-correcting control make it
is easy operate.
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.
