Plastic Single Screw Extruder For Pipe With 38 Cr Moaia Material
Barrel and Screw
Brief introduction:
1.Single screw extruder is composed of Screw, Barrel, Transmission
system, die head connector , electric control box,etc.
2.This single screw extruder can use for producing pipe, profile,
board and other plastic product.
Characteristics of the plastic single screw extruder:
1.Screw: the screw is a critical part of plastic transimission and
plasticization, because of it's rotation, then push the plastic
forward,so as to press, melt and mixing the plastic.The screw
thread is composed of different function section,so as to good
transimission, press, mixing, the plasticization is good, the
capacity is high. Screw material adopt nitrided steel(38Cr
MOAIA),the screw is made of fine nitriding and grinding, it has
hhigh corrision resistance and wear resistance,and has long service
life.
2.Barrel:It's a part that paired with the screw, the barrel is made
of nitriding steel, inner hole is nireided treatment, in order to
achieve higher hardness and good wear resistance.There are 5 units
heater in it's outside, the heat transmission through barrel to
plastic, to make plastic melt,Each part of the heater cyclinder is
provided with five temperature measuring points, it can
automatically control in the plastic process temperature range.The
five heat zone has air cooling system, it can accelerate barrel
cooling and improve the accuracy of temperature control.
3.Die head: It is the part that connect the die head and barrel,
inside has heat coil, in case of melt plastic become cool.
4.Transimission system: Transimission system makes the screw rotate
uniformly with the necessary torque under the selected process
conditions,in order to carry out the screw plasticizing and
conveying of plastic.In order to adopt different production
requirement of different material, the screw should has different
rotation speed. Our single screw extruder adopts frequency
converter, through coupling direct drive gear box, and adopt
governor to achieve speed regulation, to make the screw rotation
smooth stepless in the speed control range.
