Description
Technical field
The utility model is related to PVD plated film screw barrels, belong to screw technique field.
Background technology
Screw rod outer surface cuts with the cylinder of helicla flute or cuts with the circular cone of Conical Spiral Groove, and screw rod is plastic molding equipment
Core component, be heat extrusion plasticizing part, be plastics machinery core.The screw rod of the screw rod of prior art plated film machine barrel
Head all only has single screw rod header structure, causes barrel Inner Front End material that can not obtain sufficient stirring during discharging.For
Above-mentioned difficulties are solved, it is necessary to develop the screw rod of a PVD plated film machine barrels for twin-screw header structure.
The content of the invention
The purpose of this utility model is to provide PVD plated film screw barrels.
Problem to be solved in the utility model is that prior art plated film screw rod all only has the problem of single screw rod header structure.
To realize the purpose of this utility model, the technical solution adopted in the utility model is：
PVD plated film screw barrels, including inner cavity, the second screw head, the first agitation beads, the first screw head, the second stirring
Pearl, the first spiral shell rib, screw body, stirring ring and the second spiral shell rib, the screw body are externally provided with multiple first spiral shell ribs, the first spiral shell rib or so
Stirring ring is respectively installed in the both sides up and down at both ends, and stirring ring is equipped with multiple second spiral shell ribs, and screw body upper end periphery is equipped with multiple the
Two agitation beads install the first screw head in screw body, and the first screw head is externally provided with multiple first agitation beads, pacifies on the first screw head
The second screw head is filled, the second screw head is equipped with multiple inner cavities being recessed inwardly.
Connecting shaft is installed under the screw body.
The utility model has the advantages that：The twin-screw header structure of first screw head and the second screw head so that before in barrel
End material obtains sufficient stirring in extrusion, can reduce the bubble in extruded product；Stirring ring can fill mixing process
Divide property, uniformity more preferably, the product quality of extrusion is high, does not have bubble；Material can be pushed ahead with the first spiral shell rib, accelerate object
The discharging of material, the second agitation beads can promote the mixing of material, reduce the bubble in material.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
The utility model PVD plated film screw barrels, including inner cavity 1, the second screw head 2, the first agitation beads 3, the first spiral shell
Head 4, the second agitation beads 5, the first spiral shell rib 6, screw body 7, connecting shaft 8, stirring 9 and second spiral shell rib 10 of ring, outside the screw body 7
Equipped with multiple first spiral shell ribs 6, stirring ring 9 is respectively installed in the both sides up and down of 6 left and right ends of the first spiral shell rib, and stirring ring 9 is equipped with multiple
Second spiral shell rib 10, stirring ring 9 can make mixing process adequacy, uniformity more preferably, and the product quality of extrusion is high, does not have bubble；
7 upper end periphery of screw body is equipped with multiple second agitation beads 5, and screw body 7 time installs connecting shafts 8, the first screw rod is installed in screw body 7
First 4, the first screw head 4 is externally provided with multiple first agitation beads 3, and the second screw head 2, the second screw head 2 are installed on the first screw head 4
Multiple inner cavities 1 being recessed inwardly are equipped with, the first agitation beads 3 and inner cavity 1 can promote mixing of the material during discharging,
The twin-screw header structure of first screw head 4 and the second screw head 2 so that barrel Inner Front End material obtains fully in extrusion
Stirring, the bubble in extruded product can be reduced；Material can be pushed ahead with the first spiral shell rib 6, accelerate the discharging of material, and second
Agitation beads 5 can promote the mixing of material, reduce the bubble in material.
The utility model application method：The twin-screw header structure of first screw head 4 and the second screw head 2 so that in barrel
Front end material obtains sufficient stirring in extrusion, can reduce the bubble in extruded product；Stirring ring 9 can make mixing process
More preferably, the product quality of extrusion is high, does not have bubble for adequacy, uniformity；Material can be pushed ahead with the first spiral shell rib 6, be added
The discharging of fast material, the second agitation beads 5 can promote the mixing of material, reduce the bubble in material.
