The body of rod, the second spiral shell rib, the 3rd screw body, screw head, the 3rd spiral shell rib, stirring ring, slant edge and horizontal rib, two are installed on the supporting plate
Bearing, screw shaft is mounted on bearings, and respectively the first screw body of installation, the first screw body are externally provided with the first spiral shell rib under screw shaft, the
One screw body middle part is provided with multiple row teeter column, and the first spiral shell rib is provided with stirring ring, and stirring ring is provided with the 3rd spiral shell rib, and first
It is the second screw body under screw body, the second screw rod external surface is provided with multiple equally distributed perpendicular ribs, and the second screw body has
3rd screw body, the 3rd screw body are externally provided with the second spiral shell rib, and the 3rd screw body has screw head, and the outer middle part of screw head is horizontal
To provided with a horizontal rib of circle, longitudinal direction is provided with four slant edges to the second screw head outside, and horizontal rib and slant edge intermesh.
The first screw body quantity is two.
The utility model has the advantages that：It is more abundant that perpendicular rib can be kneaded material, while it is more fast material is elapsed forward
Speed；Screw head is pyramidal structure, and the structure that slant edge and horizontal rib interlock pushes ahead material to be more prone to；Stirring ring can make mixing
More preferably, product quality is high, does not have bubble for process adequacy, uniformity；Teeter column can promote the mixing of material；Material can be with
First spiral shell rib, the second spiral shell rib are pushed ahead, and accelerate the discharging of material；This screw rod spiral shell rib is complicated various, can improve plastics original
The mixing of material.
