NOVELTY - The utility model claims a screw device for graphene and plastic particle co-extruded, comprising two screw charging barrel and have the same structure, the two screw parallel set in the charging barrel, the screw rotating joint inside of the material cylinder; one end of the charging barrel is provided with a feeding hopper, discharge port is set on the other end of the charging barrel, the screw rod comprises multiple rotor assemblies and several reverse screw thread component, the rotor component and the reverse thread component are orderly arranged from the feed hopper to the discharge port direction. The utility model increases the rotor assembly and a reverse screw thread component on the common screw rod, it is good for the large graphene to mix with molten plastic, which solves the problem of difficult to mix the large-size graphene extruder of the reverse screw thread component to increase the pressure and shear forces in the extruder, extruder pressure is increased, the shearing force increases graphene is uniformly dispersed in the molten plastic.
