Plastic single screw extruder machine SJ55/30 tube screw extruder
machine
Application:
The extruder is mainly composed of a screw, a barrel, a
transmission system, a joint of a machine head, and an electric
control box.
A1:Screw
It is a key component for the transportation and plasticization of
plastics. Because of its rotation, the plastic is pushed forward to
achieve the purpose of compaction, melting and mixing. The thread
is composed of different functional sections to achieve better
conveying, compaction, mixing, plasticizing effect and high output.
The screw material is made of high-quality nitrided steel
(38CrMoALA), which is finished by nitriding and finishing. It has
high corrosion resistance and wear resistance and long service
life.
A2:Barrel
It is a part matched with a screw. The barrel is made of nitrided
steel, and the inner hole is nitrided to achieve higher hardness
and better wear resistance, and has a certain corrosion resistance.
There are five sets of heaters on the surface. The heat is
transferred from the barrel to the plastic to melt and plasticize
the plastic. There are five temperature measuring points in each
part of the heater barrel, which can be automatically controlled
within the plastic processing temperature range. The heating zone
of the cylinder is equipped with air circulation cooling, which can
accelerate the cooling of the cylinder and improve the accuracy of
temperature control.
A3:Head flange joint
It is a part of the joint head and the barrel, which is heated by a
heating ring to prevent the cooling of the molten plastic.
A4:Transmission system
The transmission system is to rotate the screw evenly with the
necessary torque under the selected process conditions to complete
the plasticization and transportation of the plastic to the screw.
In order to meet the production requirements of various
specifications of plastic products, the screw should have different
rotation speeds. The machine adopts the variable frequency motor to
directly drive the gear box through the coupling, and adopts the
governor to realize the speed regulation, so that the screw speed
can be smoothly steplessly regulated within the speed regulation
range, and the screw speed can be directly read by the tachometer
on the control panel. Can also be read directly on the governor
