Application of single screw extruder: The single-screw extruder is
mainly used for extruding soft and hard PVC, polyethylene and other
thermoplastics. It can process a variety of plastic products, such
as blown film, extruded tube, pressing plate, drawing ribbon, etc.,
and can also be used for melt granulation. The plastic extruder has
advanced design, high quality, good plasticization and low energy
consumption. It adopts involute gear transmission, which has the
characteristics of low noise, stable operation, large bearing
capacity and long life. The usege of single screw extruder in
various fields: A1 single screw pipe extrusion: suitable for PP-R
pipe, PE gas pipe, PEX cross-linked pipe, aluminum-plastic
composite pipe, ABS pipe, PVC pipe, HDPE silicon core pipe and
various co-extruded composite pipes. A2 Single screw plate and
sheet extrusion: suitable for the extrusion of PVC, PET, PS, PP, PC
and other profiles and plates. Extrusion of various other plastics
such as silk and rods. A3 Extrusion of single-screw profiles:
Adjusting the speed of the extruder and changing the structure of
the extruder screw can be applied to the production of various
plastic profiles such as PVC and polyolefins. Modified granulation:
It is suitable for blending, modifying and enhancing granulation of
various plastics. The core patents of Single screw extruder: A1: Extruder screw It is a key component of plastic transportation
and plasticization. Due to its rotation, the plastic is pushed
forward to achieve compaction, melting and mixing. The thread is
composed of different functional parts to achieve better conveying,
compaction, mixing, plasticizing effect and high output. The screw
material is made of high-quality nitrided steel (38CrMoALA), and is
nitrided and finely ground. It has high corrosion resistance and
wear resistance, and has a long service life. A2: Extruder head
flange joint It is part of the joint and barrel and is heated by a
heating ring to prevent the molten plastic from cooling. A3:
Extruder drive system The transmission system will evenly rotate
the screw 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 speeds. The machine uses a variable frequency motor
to directly drive the gearbox through the coupling, and uses a
speed regulator to achieve speed regulation, so that the screw
speed can be smoothly adjusted within the speed range, and the
screw speed can be directly adjusted. It is read by the tachometer
on the control panel. It can also be read directly on the governor. |
