Recycling ABS PC POM PP PE film extruder machine,plastic single
screw extruder
The extruder screw according to different materials, different
screw different optimum combination of form and the mixing element,
barrel used for the optimization design of the grooved drum and
lengthened feeding, material melting process was optimized, thus
improve the extrusion production, achieve the extrusion material
melt at lower temperatures. For different material provides a wide
range of processing range, suitable for all kinds of polyolefin
materials, especially suitable for HDPE, PP, ABS raw material
coffin.
Applications:
Single screw extruder with the proper head and auxiliaries, PE, PPR
powder can be processed into a variety of plastic products. Such as
ribbon cable insulation membrane tube bar plate and hollow
products, etc.
The structure is briefly
The machine has the following structure
1, because the screw has more sections ranging from the
characteristics of the pitch, for the heat transfer area of the
material and the shear velocity is large, promotes the plasticizing
of material, can make the melt extrusion under low temperature.
2, in the feed hopper is equipped with the magnetic body, prevent
iron, sundry fall into, protect the screw.
3, set the gear box, driving moment passed to screw gear evenly.
4, barrel heating using cast aluminum heating, long service life,
convenient installation.
5, barrel cooling by air cooling, small temperature fluctuations.
6, three-phase asynchronous motor, frequency control of motor
speed, speed stability, speed and convenient.
With 7, over current protection device, to prevent damage to parts.
(2), structure
Host by the screw, barrel, transmission system, barrel heating,
cooling system, frame, the nose join body, electric control box,
the main thing.
1, the screw
It is a complete plastic flow of key parts and plasticizing, inside
the barrel rotates, the powdered plastic plasticizing into the
nose, so as to achieve compaction, melting and mixing
homogenization. On the screw thread is composed of different pitch
section in order to achieve better transmission, compaction, mixing
and plasticizing.
2, barrel
Barrel is for plastic parts and screw, it directly with plastic and
screw friction. Barrel material is nitrided steel, after nitriding
treatment, inner hole surface with high hardness and good wear
resistance and corrosion resistance ability. The surface of the
barrel is equipped with four groups of electric heaters, heat the
barrel to the plastic, the plastic melt plasticization. Each heater
is equipped with temperature measuring points, control the heating
temperature of the barrel.
3, the head connecting body
It is the connecting head parts, it is equipped with with the nose
flange connection.
4, drive
Drive system is under the condition of the selected process, must
make the screw to rotate at a constant speed of torque, to complete
the screw plastic plasticizing and transport. In order to meet the
needs of the PE, PPR products production, the machine adopts ac
motor drive, through the elastic coupling and gear reducer drive,
make the speed of the screw 3.5-50 smooth, stepless speed
regulation in the r/min. The speed of the screw can be directly
read tachometer on the control panel.
5 and frame
Frame is made of steel, channel steel welding of steel structures.
