Abstract
A short screw extruder comprises a cylinder (1), a screw (2), and an injection shaft (3). The screw (2) comprises a screw body provided with a central through hole. The screw body comprises a left support part (2.3) and a right support part (2.4). An external screw edge (2.1) of the screw body is arranged between the left support part and the right support part. An internal screw edge (2.2) is arranged in the central hole of the screw body from a position corresponding to the right support part (2.4) in the hole. One section of the left support part (2.3) and one section of the right support part (2.4) are rotatingly matched in the cylinder (1). The injection shaft (3) is arranged in the internal screw edge (2.2). The spiral directions of the external screw edge (2.1) and the internal screw edge (2.2) are opposite. Because the external spiral channel is folded relative to the internal spiral channel, the length of screw is reduced, and thus the extruder is minimized.
Description
Technical field
The present invention relates to the technical field of extruder, be specifically related to a kind of short screw extruder.
Background technology
Screw extruder is the visual plant of plastic cement processing, and screw rod is its core component, and the length of screw rod determines the length of extruder.
In extruder, machine barrel/screw rod has three effects greatly: one is feeding conveying effect, i.e. feeding section, and two is plastication, by particulate material
It is melted into plastic cement melt, i.e. fluxing zone；Three is the extruding zone of steady extruding, melt-stoichiometry effect to be had.
The injecting products that the screw extruder quality to be expected of prior art is good must make screw rod long enough so that it has foot
Enough mixing length is with abundant heat of fusion plastic resin material, and therefore, extruder increasingly has the trend of maximization.And in recent years produce
The product delivery cycle increasingly shortens, it is desirable to the plasticizing rate of screw rod is increasingly faster, and a lot of extruders become unable to do what one wishes.
Get the raw materials ready in the injecting cavity of screw-type extruder few, needing the occasion of mass storage liquid plastics, need to accelerate instantaneous heating
Reach shot or strengthen injecting cavity to improve liquid storage amount；The former accelerates instantaneous heating needs temperature high energy big；
The injection pressure that the latter strengthens after injecting cavity is little, and injection force is not enough.Need to design that a kind of spiro rod length is short, measurement chamber is long
Extruder meets injection needs.
Summary of the invention
For defect present in above-mentioned prior art, it is an object of the invention to provide a kind of short screw extruder.
The object of the present invention is achieved like this, a kind of short screw extruder, and including machine barrel, screw rod and injection shaft, screw rod includes tool
Having the screw body of central through hole, described screw body to have left support portion and right support portion, screw body is in left support portion and right support portion
Between be provided with outer spiral shell rib, in the centre bore of screw body from right support end corresponding in be provided with interior spiral shell rib, described screw rod hole site

In, the other end is opened in internal coiling fluxing zone.
Further, described outer spiral shell rib is gradually lowered from left support portion to the pitch in right support portion identical spiral shell rib, and screw body is from left support
Portion to right support portion has the circular cone oblique angle of 5 °～25 °.
Further, screw body correspondence internal coiling fluxing zone and internal coiling extruding zone are provided with heater, and described heater is positioned at spiral shell
Near the position of central through hole wall in the body of rod.
Further, described left support portion is rotatably supported on left shaft holder, and right support portion is rotatably supported on right bearing seat.
Further, the pressing plate of gear-box and the fixing connection of the flange of machine barrel, described left shaft holder is fitted in gear-box by flange
In bearing press mounting hole.
Further, described screw body only includes left support portion, and screw body is rotatably supported in left support portion；The right-hand member of screw body is
Free end, free end extend into the spacing distance of the right baffle plate of distance in machine barrel, and this spacing distance is configured to replace the connection of intercommunicating pore
Passage.
Further, between the endoporus correspondence position in injection shaft and right support portion, it is combined with rolling bearing.
Further, injection shaft connects driving means.
Further, the side, left support portion of described screw rod is provided with the rotating driving device being arranged in gear-box, and described rotation drives
Device includes driven gear, driving gear and drive shaft, is installed with driven gear in screw body, described driven gear with
Driving gear engages, and driving gear is installed on the driving shaft.
Further, described drive shaft is rotatably provided in gear-box, and described drive shaft is driven by motor.
Described short screw extruder, designs the length having accomplished spiro rod length less than fluid passage by the following special construction of screw rod:
1) sleeve of spiral shell rib inside and outside, screw body has outer spiral shell rib and interior spiral shell rib simultaneously, and outer spiral shell rib is used for coordinating with machine barrel, interior spiral shell rib
For coordinating with injection shaft；
2) coordinating of internal and external screw passage, sleeve and machine barrel and axle, outer spiral shell rib and machine barrel cooperatively form external spiral passage, external spiral
Passage is responsible for carrying particulate material to internal coiling passage；Interior spiral shell rib and injection shaft cooperatively form internal coiling passage；
3) intercommunicating pore or communicating passage, intercommunicating pore or communicating passage are connected between external spiral passage and internal coiling passage, and connection is logical
Road is by external spiral passage and internal coiling channel connection integrant screw rod fluid passage so that external spiral passage is relative to internal coiling
Passage folds, non-rectilinear order arrangement.
By cooperating of three above structure, jointly accomplish that external spiral passage folds relative to internal coiling passage, shortened spiral shell
The length of bar, it is achieved that the miniaturization of extruder；Thermoplastic resin makes through the dynamic shearing stress of intercommunicating pore or communicating passage
Obtain resin by Flashmelt, it is simple to form the hot-melt resin of homogenizing high pressure at extruding zone；Screw design becomes the set of inside and outside spiral shell rib
Cylinder, if the sleeve that the maintenance in terms of spiral shell rib abrasion more renews, repair and replacement low cost.
