Description
Technical field
The utility model is related to taper super long type films to be granulated screw barrel, belongs to screw technique field.
Background technology
Screw rod outer surface cuts with the cylinder of helicla flute, and screw rod is the core component of plastic molding equipment, is that heating squeezes out modeling
The part of change is the core of plastics machinery.The screw rod that prior art film is granulated in machine barrel all only has single screw rod header structure,
Cause machine barrel Inner Front End material that can not obtain sufficient stirring during discharging.In order to solve above-mentioned difficulties, it is necessary to develop one
Money is granulated the screw rod of machine barrel for the taper super long type film of twin-screw header structure.
The content of the invention
The purpose of this utility model is to provide taper super long type film and is granulated screw barrel.
Problem to be solved in the utility model is that the screw rod that prior art film is granulated in machine barrel all only has single screw rod
The problem of header structure.
To realize the purpose of this utility model, the technical solution adopted in the utility model is：
Taper super long type film is granulated screw barrel, including screw body, the first spiral shell rib, perpendicular rib, the first screw head, the second spiral shell
Head, stirring ring, the second spiral shell rib, slant edge and horizontal rib, the screw body are externally provided with the first spiral shell rib, stirring are installed on the first spiral shell rib
Ring, stirring ring are equipped with the second spiral shell rib, the first screw head, the first big middle part of screw head upper and lower ends diameter are installed under screw body
Position diameter is small, and the first screw head outer surface is equipped with multiple equally distributed perpendicular ribs, and the first screw head lower end is equipped with the second screw head,
The one horizontal rib of circle outside the second screw head is installed, four slant edges are installed outside the second screw head, horizontal rib and slant edge intermesh.
Connecting shaft is installed in 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
Material is held to obtain sufficiently stirring during discharging, the bubble in extruded product can be reduced, the perpendicular rib of the first screw head can make
Material stirring is more abundant, while makes material discharging rapider；Second screw head is pyramidal structure, what slant edge and horizontal rib interlocked
Structure pushes ahead material to be more prone to, and the structure of the first screw head indent closes the second screw head pyramidal structure so that material
Discharging is rapider；Stirring ring can make mixing process adequacy, uniformity more preferably, and product quality is high, does not have bubble；Material energy
As the first spiral shell rib is pushed ahead, accelerate the discharging of material.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
The utility model taper super long type film is granulated screw barrel, including screw body 2, the first spiral shell rib 3, perpendicular rib 4, first
Screw head 5, the second screw head 6, stirring ring 7, the second spiral shell rib 8, slant edge 9 and horizontal rib 10, the screw body 2 are externally provided with the first spiral shell rib
3, installation stirring ring 7 on the first spiral shell rib 3, stirring ring 7 is equipped with the second spiral shell rib 8, and stirring ring 7 can make mixing process adequacy,
More preferably, product quality is high, does not have bubble for even property；Material can be pushed ahead with the first spiral shell rib 3, accelerate the discharging of material, spiral shell
2 times the first screw heads 5 of installation of the body of rod, the big middle part diameter of 5 upper and lower ends diameter of the first screw head is small, outside the first screw head 5
Surface is equipped with the twin-screw header structure of multiple equally distributed perpendicular ribs 4, the first screw head 5 and the second screw head 6 so that in barrel
Front end material obtains sufficiently stirring during discharging, can reduce the bubble in extruded product, the perpendicular rib 4 of the first screw head 5
Material stirring can be made more abundant, while make material discharging rapider；First screw head, 5 lower end is equipped with the second screw head 6, the
The one horizontal rib 10 of circle of installation outside two screw heads 6, the second screw head 6 install four slant edges 9 outside, and horizontal rib 10 and slant edge 9 intermesh, the
Two screw heads 6 are pyramidal structure, and the structure that slant edge 9 and horizontal rib 10 interlock pushes ahead material to be more prone to, the first screw head 5
The structure of indent closes 6 pyramidal structure of the second screw head so that material discharging is rapider；Connecting shaft 1 is installed in screw body 2.
The utility model application method：The twin-screw header structure of first screw head 5 and the second screw head 6 so that in barrel
Front end material obtains sufficiently stirring during discharging, can reduce the bubble in extruded product, the perpendicular rib 4 of the first screw head 5
Material stirring can be made more abundant, while make material discharging rapider；Second screw head 6 is pyramidal structure, slant edge 9 and horizontal rib
10 structures staggeredly push ahead material to be more prone to, and the structure of 5 indent of the first screw head closes 6 taper knot of the second screw head
Structure so that material discharging is rapider；Stirring ring 7 can make mixing process adequacy, uniformity more preferably, and product quality is high, will not
There is bubble；Material can be pushed ahead with the first spiral shell rib 3, accelerate the discharging of material.
