The utility model has the advantages that：In stirring mix stage, the first screw head is located at barrel front end, and steel ball, which contradicts, is expecting
In medial wall of the tube, compression spring, make puddler lower end more in groove；Sealing ring is avoided that material enters groove
In, the first screw head with the second screw body rotate when, puddler rotates also with the second screw body；Discharging stage is being molded,
When second screw body is rotating the injection discharging opening for being moved rearwardly away from barrel, the first screw head also with the second screw body backward
Mobile, puddler ejects forward under the restoring force effect of spring, more puddlers is removed outside groove, before making puddler
End makes the material of barrel front end can still be stirred between barrel front end and the first screw head so that and injection effect is good,
It will not make to produce bubble in product；The twin-screw header structure of first screw head and the second screw head so that barrel Inner Front End material
Sufficiently stirring is obtained in extrusion, the bubble in extruded product can be reduced；Material can push ahead with spiral shell rib, accelerate
The discharging of material, the second teeter column and the first teeter column can promote the mixing of material；Perpendicular rib can make material stirring more abundant, together
When make material discharging it is rapider.
