φ120mm cable extruder Machine: Machine Description: - Screw diameter 120mm
- Screw structure BM screw
- Screw L/C 25:1
- Screw speed: 0-70r/min
- Extrusion volume: PVC: 800kg, PE600KG
- The material of the screw and barrel is 38CrMoAl, the hardness
requirements: the barrel is not less than 900HV, the screw is not
less than 760HV, nitriding treatment, corrosion resistance and wear
resistance.
- Motor power: AC variable frequency motor.
- The screw adopts the design method of the arc-shaped screw rib
structure, and the extrusion quality is much better than that of
other forms of screw; the screw design adopts the heat pipe
technology. It can prevent plastic from overheating and decompose
while strengthening shearing; improve plasticization and
homogenization of plastics; ensure high-speed extrusion and
homogenization of plastics; ensure high-speed extrusion of
plastics.
- The barrel is heated by cast aluminum heater.
- The number of temperature control sections in 6 areas of the
fuselage and the number of temperature control sections in 4 areas
of the crosshead. The fuselage adopts electric heating and air
cooling, and the maximum heating temperature of the barrel is 300
℃. The fuselage and the machine head are equipped with temperature
measuring holes. The thermocouple adopts a spiral compression
spring type, and the contact point of the temperature sensing head
can be adjusted manually on the thermocouple without any tools.
- The transmission gear adopts hard surface grinding, forced
lubrication by pressure oil, and has the function of oil pressure
protection. The gear box model is 375.
