Extrusion Machine PET Plastic Steel Strapping Production Line PP
Strapping Equipment for Single Station Wrapping Machine
PRODUCT DESCRIPTION
PET packing strap, also known as PET plastic belt, is a world
widely used new type package material substitute for steel belt.
With years development on it and decrease on cost, it is now widely
used in steel industry, chemical fiber industry, Aluminum industry,
paper industry, Brick ceramics, Screw industry, tobacco industry,
electric industry, textile industry and wood industry. It is most
widely used steel belt substitute with high strength.
Extrusion scre:---The extruder of the PET plastic steel belt production line adopts a
PET special screw with a unique parameter design. The screw has a
unique separation and mixing effect, which ensures the uniform
plasticization of the raw materials. It has the advantages of large
extrusion volume, good plasticization, high hardness, and high wear
resistance.
Extrusion scre---The flow channel is extruded evenly, with high
hardness, wear resistance and corrosion resistance, and long
service life.

Features of Plastic Strapping
(1) high tensile strength, both strip-like tensile strength, but
also can impact scalability, better ensure transportation safety
products.
(2) Small elongation, elongation rate is one-sixth of polypropylene
tape, can long maintain the tension.
(3) temperature resistance, melting point of 260 degrees, 120
degrees below the use of deformation.
(4) safety, without risk of pollution rusty steel tied objects,
bright colors to be learned.
(5) economic good, one ton PET packaging belt length equivalent to
6 tons with the specifications of the strip length, unit price per
meter more than 40% lower than steel, to reduce packaging costs.
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.
