Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a spinneret for fibers. Background Art

[0002] In chemical fiber production, the ejection method of the spinneret has a significant impact on the quality and production efficiency of the fiber. Usually, "fiber plane spinning" means that the micropores on the spinneret are evenly distributed along a plane, so that the ejected fiber streams will solidify into fibers roughly in the same plane direction, forming a curtain-like fiber output form.

[0003] During the production process of fibers, the toughness and bendability of the fibers themselves can be improved by changing their internal structure. However, when the existing spinnerets are used to produce fibers in a plane, the spinneret holes on them are difficult to change the internal structure of the fibers, so that the internal structure of the produced fibers forms a multi-dimensional structure. Therefore, there is an urgent need to develop a fiber spinneret to improve the above technical problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a fiber spinneret in view of the deficiencies of the above-mentioned prior art, which can change the internal structure of the fiber during plane spinning, so that the inside of the fiber forms a multi-dimensional structure, thereby improving the toughness and bendability of the fiber.

[0005] The technical solution adopted by the utility model is: a spinneret for fiber, comprising a spinneret body for producing fiber and a spinneret hole group thereon, wherein the spinneret hole group is composed of a plurality of spinneret holes in a uniform annular array;

[0007] A first confluence groove is provided at the lower end of each guide hole on the guide plate, and a second confluence groove is provided at the upper end of each spinneret hole on the spinneret plate, and the spinning melt flowing in the guide holes is converged into the spinneret hole through the first confluence groove and the second confluence groove.

[0008] Preferably, the first confluence groove and the second confluence groove are both hemispherical structures.

[0009] Preferably, an annular guide groove is provided on the upper surface of the guide plate, and the annular guide groove is connected to each guide hole.

[0010] Preferably, a chamfer is provided at the connection point between each of the guide holes and the annular guide groove.

[0024] See also Figure 1 The embodiment of the utility model provides a spinneret 1 for fibers, comprising a spinneret 1 and a guide plate 2 which are used in conjunction with each other, the guide plate 2 is provided with an annular guide groove 5 and a guide hole group which is connected to the annular guide groove 5, and a spinneret hole group which is adapted to and connected to the guide hole group is provided on the spinneret 1.

[0025] The spinning melt formed by the fiber raw material is injected into the annular guide groove 5, and flows through the guide hole 3 groups and the spinneret hole 4 groups in sequence under the action of pressure, and finally flows out of the spinneret hole 4 groups to form a stable fiber material.

[0026] In some embodiments, see Figure 1 and Figure 2 The guide hole group and the spinneret hole group are respectively composed of a plurality of uniform annular arrays of guide holes 3 and spinneret holes 4. The spinneret plate 1 and the guide plate 2 are assembled with each other, so that the spinneret holes 4 and the guide holes 3 correspond to each other and are connected with each other.

[0027] In some embodiments, see Figure 2 Each guide hole 3 is connected to the annular guide groove 5 at a chamfered position, so that the spinning melt flowing in the annular guide groove 5 can flow into the guide hole 3.

[0028] In some embodiments, see Figure 2 and Figure 3 The flow guide hole 3 is a cylindrical hole with a through top and a closed bottom, and a diversion hole 6 is provided on the side wall at the bottom of the flow guide hole 3 .

[0029] The spinning melt flowing in the guide hole 3 is diverted through the diversion hole 6 opened at the bottom, so that the flowing spinning melt forms a plurality of preliminary fiber materials with the same cross-sectional shape at the diversion hole 6, and the plurality of preliminary fiber materials with different cross-sectional shapes are converged into the spinneret, and finally, under the action of the spinneret hole 4, a fiber material with a multi-dimensional internal structure is formed, thereby improving the toughness and bendability of the fiber material itself.

[0030] In some embodiments, see Figure 2 and Figure 3 A first confluence groove 7 is provided at the lower end of each guide hole 3 on the guide plate 2, and a second confluence groove 8 is provided at the upper end of each spinneret hole 4 on the spinneret 1. Both the first confluence groove 7 and the second confluence groove 8 are hemispherical structures.

[0031] Under the action of the first confluence groove 7 and the second confluence groove 8, multiple strands of preliminary fiber materials with the same cross-sectional shape ejected from the diversion hole 6 can be better converged into the spinneret hole 4, so that the spinneret hole 4 forms a stable fiber material with a multi-dimensional internal structure.

[0032] In some embodiments, see Figure 3 The spinneret hole 4 is a smooth cylindrical hole, which ensures the smoothness of the fiber material surface, avoids the generation of fluff or burrs on the fiber material surface, and improves the quality of the fiber material.

[0033] In some embodiments, the flow diversion holes 6 at the bottom of each flow guide hole 3 on the guide plate 2 may have different shapes.

[0034] By changing the outflow shape of the diversion hole 6, the cross-sectional shape of the multiple strands of preliminary fiber materials with the same cross-sectional shape formed by the diversion is changed, so that the internal multi-dimensional structure of the final fiber material formed at the spinneret hole 4 is different, thereby being able to produce fiber materials with different internal multi-dimensional structures.

[0035] In summary, when a fiber spinneret 1 according to an embodiment of the utility model is used, the spinning melt formed by the fiber raw material is injected into the annular guide groove 5, and flows into the guide hole 3 on the guide plate 2 under the action of pressure, and at the same time, the chamfer provided at the connection between the guide hole 3 and the annular guide groove 5 facilitates the spinning melt to flow into the guide hole 3;

[0036] When the spinning melt flows into the bottom of the guide hole 3, the spinning melt flowing in the guide hole 3 is diverted through the diversion hole 6 opened at the bottom thereof, so that the flowing spinning melt is ejected at the diversion hole 6 and forms a plurality of preliminary fiber materials having the same cross-sectional shape. Under the action of the first confluence groove 7 and the second confluence groove 8 of the hemispherical structure, the plurality of preliminary fiber materials ejected from the diversion hole 6 are converged into the spinneret hole 4 for combination. Finally, under the action of the spinneret hole 4, a fiber material having a multi-dimensional internal structure is formed, thereby improving the toughness and bendability of the fiber material itself.
