The indentation Candlewick filter filtering of acetate fiber slurries, then spinneret cap is transported to by feed pipe, is distributed on spinneret cap many outer
The small eyelet of tens microns of diameter is sprayed into the fiber strand silk of required diameter by these small eyelets.In order to keep fiber strand silk smooth
It throws away, quantity, aperture and the emission direction of small eyelet need stringent cooperation, otherwise can twine and stir together, cannot be at silk.This
The experiment that the cooperation of a little parameters generally requires thousands of times just can determine that.
At present in spinneret cap small eyelet negligible amounts, production efficiency is relatively low, how to increase small eyelet quantity
In the case of also ensure spinneret quality become urgent need to resolve the problem of.
Disclosed in Chinese patent literature CN103276462A《A kind of spinneret cap》, including plate-like ontology has on ontology
It is taper hole to have several perforative spinneret orifices, spinneret orifice, and there are three inclined guide parts for spinneret orifice inside tool, and guide part is by spinneret orifice
Gradient is gradually reduced at large port to portlet, spinneret orifice along body plane direction section be in equilateral triangle, spinneret orifice it is small
Port is straight hole, and portlet is equilateral triangle along the section in body plane direction, and the length of side of equilateral triangle is at portlet
0.02mm to 0.1mm.
Above-mentioned spinneret cap only solves the problems such as existing spinneret cap pore structure is complicated, difficulty of processing is big.But it can not
It solves the problems, such as to ensure spinneret quality in spinneret cap in the case where increasing eyelet quantity.
Invention content
The utility model is directed to insufficient existing for the spinneret cap in existing spinning-drawing machine, provides that a kind of spinneret is efficient, operation
Stablize, ensure the fibre spinning spinneret cap of spinneret quality.
The fibre spinning spinneret cap of the utility model, using following technical proposals：
Perforative spinneret orifice is distributed on bottom plate in the spinneret cap, including bottom plate；Spinneret orifice successively include the big tapering of seal wire,
The big end of the small tapering of seal wire and wire vent straight hole, the big tapering of seal wire carries chamfered section；The big tapering of seal wire and the small tapering of seal wire it is transversal
Face is equilateral triangle, and is inclined-plane per one side；It is each that the oblique angle of each side in the big tapering of seal wire is more than the small tapering of seal wire
The oblique angle of side；The cross section of wire vent straight hole is equilateral triangle, and three sides are to face directly (cross sectional dimensions is consistent everywhere).
The big end equilateral triangle length of side in the big tapering of seal wire is 2~2.5mm.
The oblique angle of the big tapering side of seal wire is 25~30 degree.
The outside diameter of the chamfered section is 1.5~2mm.
The taper of the chamfered section is 15~20 degree.
The oblique angle of the small tapering side of seal wire is 10~15 degree.
The equilateral triangle section length of side of the wire vent straight hole is 0.05~0.06mm.
The height of the wire vent straight hole is 0.01~0.04mm.
The big end in the small tapering of seal wire is 0.06~0.2mm at a distance from bottom plate bottom surface.
The spinneret cap of the utility model passes through chamfered section, the big tapering of seal wire and seal wire conelet before wire vent straight hole wire vent
Three sections of guiding in portion and everywhere size and angular compliance, make spinning solution be emitted according to direction initialization, ensure that spinning solution
Smooth ejection, spinneret is efficient, stable, ensure that spinneret quality.

Portion.
Specific implementation mode
As shown in Figure 1, the fibre spinning spinneret cap of the utility model, including bottom plate 1, one end periphery setting of bottom plate 1 are outer
Along 2, bottom plate 1 and outer 2 constitute spinneret cap main body.Such as Fig. 2, perforative spinneret orifice 3 is distributed on bottom plate 1, spinneret orifice 3 is with bottom plate
1 center is distributed in concentric circles, and the spinneret orifice 3 on same circumference is uniformly distributed.
Such as Fig. 3 and Fig. 4, spinneret orifice 3 includes leading successively from the inner face (one end of setting outer 2) of bottom plate 1 to outer end face
The big end of the big tapering 7 of silk, the small tapering 5 of seal wire and wire vent straight hole 4, the big tapering of seal wire 7 carries chamfered section 6.It the big tapering of seal wire 7 and leads
The cross section (plane for being parallel to 1 end face of bottom plate) in the small tapering of silk 5 is equilateral triangle, and is inclined-plane, seal wire per one side
