Each section of filament spinning component undertakes the function of distribution melt, filtering and blend spinning melt.At present, the core material and skin of spinning melt
Material is to carry out being extruded into strand by common spinneret micropore after mixing, in this case, due to core material
Fusing point is low, and the fusing point of cladding is high, during blend melt flow in micropore, cladding compared with being easier curing for core material, from
And so that blend melt flow velocity is slack-off, it is difficult to ensure to squeeze out the strand of high quality.
Therefore, there is an urgent need for a kind of novel melt-spun composite spinneret components.
Utility model content
The purpose of this utility model is that for the above-mentioned prior art the shortcomings that, provide a kind of melt-spun composite spinneret group
Part, the component are described to have into slurry seat tool from top to bottom successively by being formed into slurry seat, distribution plate, intubation plate and spinneret board stacking
Core material inlet pipeline and cladding inlet pipeline, the core material inlet pipeline connect core material chamber, and the cladding inlet pipeline connects skin
Expect chamber, the core material and cladding respectively from respective core material chamber and cladding chamber reallocated by the distribution plate, intubation plate after to
Up to the spinneret, the spinneret has multiple micropores, and each micropore includes core material hole and the cladding around the core material hole
Annular distance, the core material hole have core material import, and the cladding annular distance has cladding import, the intubation in the core material of the core material chamber
Into the core material import, the cladding of the cladding chamber enters the cladding import, and the core material and the cladding are described micro-
The exit mixing in hole.
Preferably, the diameter of the cladding annular distance entrance is more than the diameter in the cladding annular distance exit.
Preferably, the near exit of the cladding annular distance has the gradual change portion from major diameter annular distance to minor diameter annular distance.
Preferably, it is 2~4 that the ratio between the length of minor diameter annular ring member and outer diameter, which are draw ratio,.
Preferably, the distribution plate includes the first distribution plate and the second distribution plate.
Preferably, the component bottom further includes trim ring, and entire component is fixedly mounted by the trim ring.
The utility model has the advantages that：
The utility model proposes melt-spun composite spinneret component, can be by skin by the specific structure of spinneret micropore
Material and core material are squeezed out from different holes respectively, and fusing point difference will not influence each other so as to two kinds of larger materials of the temperature difference, are solved
The problem of overall flow is not smooth, so as to promoting the quality of spinning.

Specific embodiment
With reference to specific examples below and attached drawing, the utility model is described in further detail.
As shown in Figures 1 to 3, a kind of melt-spun composite spinneret component of the utility model, the component from top to bottom successively by
It is formed into slurry seat 1, the first distribution plate 2, the second distribution plate 3, intubation plate 4, spinneret 5 and trim ring 6.Trim ring 6 consolidates entire component
Dingan County fills, and passes through screw 7 and lock.It is described that there is core material inlet pipeline 11 and cladding inlet pipeline 12, the core material into slurry seat 1
Inlet pipeline 11 connects core material chamber 13, and the cladding inlet pipeline 12 connects cladding chamber 14, and the core material and cladding are respectively from each
From core material chamber 13 and cladding chamber 14 pass through first distribution plate 2, the second distribution plate 3, intubation plate 4 reallocate after reach described in
Spinneret 5.First distribution plate 2 makes core material, cladding distinguish pressure balance in component internal.Second distribution plate 3 walks core material, cladding
Spinneret 5 is flowed to by different channels.
With reference to figure 3 (b), there are the spinneret multiple micropores (the section signal of the micropore of left and right two is illustrated only in Fig. 1
Figure), each micropore 8 includes core material hole 81 and the cladding annular distance 82 around the core material hole.The core material hole 81 have core material into
Mouthful 81a, the cladding annular distance 82 have a cladding import 82a, the core material of the core material chamber 13 by the intubation 41 that is intubated in plate 4 into
Enter the core material import 81a, the cladding of the cladding chamber 14 enters the cladding import 82a, and the core material and the cladding exist
The exit mixing of the micropore 8.
Referring again to the micropore enlarged local section schematic diagram of Fig. 2, the diameter of 82 entrance of cladding annular distance is more than described
The diameter in cladding annular distance exit, i.e., including major diameter annular distance 83 above and following minor diameter annular distance 84.It is mentioned here
Diameter refers to the diameter of the outer shroud of cladding annular distance.The near exit of the cladding annular distance 82 have from major diameter annular distance 83 to it is small directly
The gradual change portion 85 of diameter annular distance 84.That is the annular distance diameter in the gradual change portion 85 tapers into.Preferably, the length of minor diameter annular distance (hole pipe)
The ratio between degree and outer diameter i.e. draw ratio are 2~4.For example, length can be 1.2cm, outer diameter can be 0.3cm, then draw ratio is 4.
It can ensure that cladding will not be too thick, can increase the intensity of fiber in this way.
By the specific structure of the utility model spinneret micropore, cladding and core material can be squeezed from different holes respectively
Go out, fusing point difference will not influence each other so as to two kinds of larger materials of the temperature difference, solve the problems, such as that overall flow is not smooth, be promoted
The quality of spinning.
The protection content of the utility model is not limited to above example.In the spirit and model conceived without departing substantially from utility model
Under enclosing, various changes and advantages that will be apparent to those skilled in the art are all included in the utility model, and with appended power
Sharp claim is protection domain.
