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.
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.
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.
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.
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.
