Changed the shape of the screw design, increase the screw between the thread spacing in the heating can make the plastic in the barrel of the full plastic melting, the use of variable-diameter, the technology to increase the relative life of the screw, the use of high-strength 38CrMoAlA materials to improve the performance of the entire machine.
The design of the barrel adopts by steel after the fine processing quenching treatment has the high hardness and certain wear and corrosion resistance performance, and in the feed end sets has the certain size slot hole, facilitates the feeding.
The heating system is composed of heating coil, distributed separately in the barrel, the material in the barrel is heated and plasticized, and the control of the instrument on the cabinet is made, and the change of setting temperature is formed automatically.
In order to achieve the stability of the temperature in the barrel, the design on the bottom of the cylinder to increase the cooling fan, through the automatic temperature control when the temperature is too high to automatically cool, increasing the barrel temperature stability.
In order to maintain the extrusion of plastic will not appear due to temperature reduction, lack of liquidity, hinder extrusion. A certain power heating circle is added to the Machine head to ensure the normal fullness of the discharging. And the discharging hole which is set on the nose is parallel 15-hole type, and the output quantity increases the production speed. The head structure type parallel extruding head, the thread is connected with the material barrel, when replacing the net board can save time and effort.
