Abstract:
 Abstract:Aiming at the problem of large temperature difference,material heating nonuniformly and long
preheating time of plasticizing machine and extruding machine,a new material was proposed conveying
heating technology based on principle of induction motor. Electromagnetic coils were placed inside cylin-
der,so high frequency alternating radial magnetic field was produced,flux line constitute a closed loop
by cylinder,air gap and rotor screw,so cylinder and rotating screw were induced as heat sources. The
material was mixing heated when screw rotating conveying,heating efficiency and heating uniformity were
improved. Eddy current distribution of barrel and screw rotor were simulated, influence of air gap,slot
width,frequency on heating power and heating performance were analyzed,and selection principle of rel-
evant parameters was given. Heating experiment for rubber plasticizing machine was carried out,and the
experiment results show that the material conveying heating technology on the principle of induction motor
reduces the radial temperature difference to 10 0C,the equipment preheating time is shortened to 70 min.
