Screw The design of the screw has been changed, and the thread pitch between the screws has been increased to enable the plastic to be fully plasticized and melted in the barrel during heating; the variable diameter type has been used to increase the relative service life of the screw; High-strength 38CrMoAlA 18618 142980 Zhang Qingbo improves the performance of the entire machine. Barrel The design of the barrel adopts 45# steel after fine processing and quenching treatment with high hardness and certain wear and corrosion resistance, and a certain size of slot is provided at the feeding end to facilitate feeding. Heating system The heating system is composed of heating coils, which are separately distributed outside the barrel, and the material in the barrel is uniformly heated and plasticized, and controlled by the instrument on the electric cabinet to form a change automatically adjusting the set temperature. Cooling fan In order to achieve the stability of the temperature inside the barrel, a cooling fan is added to the bottom of the barrel, and the temperature is automatically controlled when the temperature is too high, which increases the temperature stability of the barrel. Machine head In order to keep the extruded plastic from appearing due to temperature drop, the fluidity is insufficient to hinder the extrusion. Specifically, a heating coil of a certain power is added outside the machine head to ensure normal and full discharge. And the discharge hole set on the machine head is parallel 15 hole type, which increases the discharge amount and increases the production speed. The machine head structure parallel extruder head, the thread is connected with the barrel, which can save time and effort when replacing the stencil. Pelletizing system After the strip is cooled by the cooling system, it enters the pelletizer and is rolled into pellets for convenient packaging. A rolling feed wheel is arranged on the granulator, and the material is automatically transferred to the body by the motor, and the rolling blade inside the body is cut.
