Abstract

A kind of extruder screw, screw-rod structure die orifice end starts to be divided into successively: die orifice section, compression homogenizing one section, compression section, feeding section, compression homogenizing one section surface has groove, the cross section of described groove is rectangle, die orifice segment structure is conical, and this screw rod manufacturing process is simple, compact conformation, save raw material and process time, improve operating efficiency.

Description

A kind of extruder screw
Technical field
The utility model relates to a kind of screw rod, specifically relates to a kind of extruder screw.
Background technology
Extruder screw is the most important parts of extruder equipment, and it is directly connected to extruder plasticizing effect and output.Extruder screw in barrel rotary work HTHP turn round greatly refuse under carry out, it powerfully in rotation will promote material reach, promote material to advance in screw channel, and be molten mass by material by Solid State Transformation, and shearing is formed to it, by certain compression ratio level pressure quantitative to machine head port mould feed, the effective length of its screw thread of conventional screw is divided into feeding section (transportation section), compression section (fluxing zone) and metering section (homogenizing zone) usually.
Chinese utility model patent (application number 201220534471.7) provides a kind of extruder screw of Split type structure, screw-rod structure die orifice end starts to be divided into die orifice section, homogenizing zone, transportation section, compression section, extruded segment, feeding section successively, adopt screw rod to connect between every section or adopt key to connect or adopt and be welded to connect, the every segment structure form of this screw rod is different, can adapt to the different requirements of each section of extrusion process.But if having longer requirement to compression section, for extruding the plastics of thermally-stabilised difference, this screw rod processing and manufacturing process is too complicated comparatively speaking, and manufacturing cost is high.
Utility model content
For solving the above-mentioned problem points that has or shortcoming, the utility model provides a kind of extruder screw, and this screw-rod structure is compact, and form is simple, and manufacturing process is easy.
To achieve these goals, the utility model extruder screw realizes by following technical scheme:
This extruder screw, is characterized in that: described screw-rod structure die orifice end starts to be divided into successively: die orifice section, compression homogenizing one section, compression section, feeding section.
Further, described compression homogenizing one section surface has groove, and the cross section of described groove is rectangle.
Further, described die orifice segment structure is conical.
The beneficial effects of the utility model are: this screw rod manufacturing process is simple, compact conformation, and compression travel can play again the effect of homogenizing material while increasing, save raw material and process time, improve operating efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the schematic diagram of extruder screw;
Fig. 2 is the sectional view of extruder screw.
Wherein Reference numeral is expressed as: 1-die orifice section, and 2-compresses homogenizing one section, 3-compression section, 4-feeding section, 5-groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, further illustrate the utility model extruder screw.
Extruder screw as shown in Figure 1, 2, screw-rod structure die orifice end starts to be divided into successively: die orifice section 1, compression homogenizing one section 2, compression section 3, feeding section 4, compression homogenizing one section surface has groove 5, the cross section of groove 5 is rectangle, die orifice section 1 structure is conical, the draw ratio of screw rod is 20:1, and the compression ratio of screw rod is 1 ~ 2.5:1.
This screw rod manufacturing process is simple, and arrange compression homogenizing one segment structure, make whole screw-rod structure compacter, save raw material and process time, compression travel can play again the effect of homogenizing material while increasing, improve operating efficiency.
Above embodiment, only in order to the technical solution of the utility model to be described, can not limit scope of the present utility model with this; To the amendment that the technical scheme described in foregoing embodiments is carried out, or to the equivalent replacement that wherein portion of techniques feature is carried out, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model, all should still belong in scope that the utility model patent contains.
