Face shape is unfavorable for modern's demand changeable to false eyelashes；There are feed openings and discharge hole arrangement not to conform to for traditional spinneret simultaneously
The defect of reason, spinneret low efficiency.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of design reasonable, easy to use and energy
Enough manufacture the filametntary spinneret of different cross section shape PBT.
To achieve the goals above, the technical solution of the utility model is:
For producing the filametntary spinneret of PBT, including spinnerette body, the spinnerette body is stepped knot one kind
Structure, spinnerette body include charging face and discharge feed side, and the charging face edge offers annular groove, and the annular slot cross-section is in
Ladder structure of right angle, the annular groove bottom offer multiple regularly arranged feed openings, and the discharge feed side offers multiple rule
The spinneret orifice then arranged offers multiple channels, the one end of the channel and feed opening connection inside the spinnerette body, another
End and spinneret orifice connection.
Further, the feed opening is arranged in annular groove in circular array, and single feed opening is in inverted rotary table
Shape structure, feed opening two corresponding buses are in angle, and the angle is α, and α is 60 °~120 °.
Further, the channel and spinneret orifice connection end offer chamfering.
Further, the spinneret orifice circular array shape is arranged in discharge feed side, and the depth of spinneret orifice is less than 3mm, spinneret
The diameter in hole is less than 2mm.
Further, the spinneret orifice section is butterfly.
Further, the spinneret orifice section is the triangle that the tangent shape of circular arc is formed.
Further, the spinneret orifice section is the cross of the tangent formation of circular arc.
Further, the spinneret orifice section is ellipse.
The utility model has the following beneficial effects: a kind of for producing the filametntary spinneret of PBT, spinneret charging face is opened
If groove, charging face is in middle part protrusion, and the PBT fiber of viscous state is directly from middle part convex transitional to charging face in process of production
In the feed opening of bottom portion of groove, accelerate the charging of PBT fiber flowed while viscous state PBT fiber being prevented to be jammed in spinneret
Face influences working efficiency, and spinneret orifice is in truncated cone-shaped structure, while being connected to channel, is conducive to viscous state PBT fiber and flow to charging
In hole, increase ductility, the effective performance indicator for improving PBT of spinneret；Spinneret orifice section is that various shapes can be effective
Improve the single problem of the spinneret orifice of traditional spinneret, while the filametntary shape of PBT changed by the shape in spinneret orifice section,
To increase the bond area of false eyelashes, working efficiency is improved；The fibre that spinneret spinneret orifice of different shapes manufactures simultaneously
Dimension silk can be used for the production of different articles, improve service efficiency.
