Description
Technical field
Field of plastics processing is the utility model is related to, specifically a kind of difunctional feed screw.
Background technology
Plastics are the raw materials based on synthetic resin or natural resin, add (or being not added with) various plastic additives, strengthening material
Material and filler, under certain temperature, pressure, type or crosslinking curing shaping, the solid material or product obtained is made in processing modeling；Plastics
Refer to resin (or using monomer direct polymerization in process) for main component, with plasticizer, filler, lubricant,
The additives such as toner are auxiliary element, in process can flowing forming material, be synthesis high-molecular compound, can be with
Freely change body styles；Using material of the raw material monomer to synthesize or condensation reaction is polymerized, by synthetic resin and filler,
The additives such as plasticizer, stabilizer, lubricant, colorant composition, its main component is synthetic resin.
During plastics-production, extruder is often used, is handled in extruder feeding outside normal feeding pellet, warp
Often online rim charge or clean crushed material can be fed extruder, still, once pellet and crushed material feed extruder simultaneously
When, it may appear that crush rim charge and lamination occurs in pellet, crushed material can be difficult to mix feeding extruder, mesh with pellet
Preceding most of effects for using common vertical screw, primarily serving mixing pellet and crushed material；Play what is slightly pushed in addition
Effect；But it is not good enough there are still feeding efficiency, extruder decompression phenomenon be present.
Utility model content
The purpose of this utility model is to provide a kind of difunctional feed screw, to solve what is proposed in above-mentioned background technology
Problem.
To achieve the above object, the utility model provides following technical scheme：
A kind of difunctional feed screw, including difunctional feed screw body；The difunctional feed screw body be by
Vertical screw axle, backgauge flange, continuous blade, interruption blade composition；Wherein vertical screw axle is deeply to feed opening and extruder
Screw rod intersection, intersection are provided with pulling tray valve more, and vertical screw shaft length extends to 2 centimeters above pulling tray valve；Backgauge flange,
Continuous blade and interruption blade ring are around on vertical screw axle；The backgauge flange welding between reductor and blade,
Prevent that friction causes to lump dust for a long time in speed reducer output shaft part for a long time；Continuous blade is arranged under backgauge flange
Side, continuous blade are connect using whole lap welding, and continuous blade mainly reaches the purpose of continuous forced conveyance pellet and crushed material, avoids
All interruption blades when material may be caused to skid cause to allow material phenomenon；The interruption blade encloses uniform etc. set up separately using whole
Put the effect in the bottom of continuous blade, primarily serving pellet and crushing rim charge mixing.
As further program of the utility model：The vertical screw axle is integrally formed using copper to be fabricated.
As the utility model further scheme：The continuous blade cast using low-alloy high-tensile structural steel and
Into.
As the utility model further scheme：It is described interruption blade using low-alloy high-tensile structural steel cast and
Into.
As the utility model further scheme：The backgauge flange is fabricated using stainless steel.
Compared with prior art, the beneficial effects of the utility model are：
The utility model between reductor and blade between be provided with backgauge flange, can prevent dust for a long time in reductor
Friction causes to lump output shaft part for a long time；Using continuous blade and interruption blade, playing pellet and crushing rim charge mixing
Effect while avoid all interruption blades when material may be caused to skid cause to allow material phenomenon, feed so as to improve
The efficiency of material.
Brief description of the drawings
Fig. 1 is a kind of structural representation of difunctional feed screw.
In figure：Vertical screw axle 1, backgauge flange 2, continuous blade 3, interruption blade 4.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, in the utility model embodiment, a kind of difunctional feed screw, including difunctional feed screw sheet
Body；The difunctional feed screw body is made up of vertical screw axle 1, backgauge flange 2, continuous blade 3, interruption blade 4；Its
