Description

Technical Field

[0001] This utility model relates to the field of polyamide spinning production technology, and in particular to a device for adjusting the diameter of an ultra-fine denier monofilament fiber die spinneret. Background Technology

[0002] In the production of ultrafine denier monofilament, the molten material needs to pass through the micropores of a spinneret and be cooled and solidified to become nascent fibers. The spinneret is a crucial core component in the production of functional fibers. Due to market changes, the spinnerets used for different product types vary. However, once produced, the diameter of the spinneret is fixed and cannot be changed. Since different product types require different equipment to produce them, the spinneret model is limited and cannot be used interchangeably. A single model of spinneret can only be used on a fixed production line assembly, resulting in poor versatility. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a microfiber spinneret diameter-changing device for ultra-fine denier monofilament fiber molds, which can improve the versatility of spinnerets.

[0004] This utility model is implemented as follows:

[0005] This utility model provides a microfiber spinneret diameter-changing device for a microfiber die, including a spinneret plate. The spinneret plate is composed of a first circular body and a second circular body, wherein the diameter of the second circular body is smaller than that of the first circular body. The diameter-changing device also includes a collar with a mounting hole for mounting the spinneret plate. The mounting hole is composed of a first fitting hole and a second fitting hole. When the spinneret plate is installed in the mounting hole, the first circular body is located in the first fitting hole, and the second circular body is located in the second fitting hole.

[0006] Furthermore, the second circular body has a positioning groove on its side wall, and the inner wall of the second fitting hole is connected to a positioning pin that matches the positioning groove.

[0007] Furthermore, the fit between the first circular body and the first fitting hole is a transition fit.

[0008] The advantages of this invention are as follows: by designing a variable diameter collar, a small spinneret can be used on a large-diameter component after being assisted by a large variable diameter collar, reducing the need for spinneret purchases and single-use methods. The collar concentrates the spinneret holes in the center of the spinneret, increasing the distance between the fiber and the side blower box. Especially for products with porous single-fiber fine denier filaments, increasing the distance between the fiber and the side blower box can reduce the wind speed around the fiber, reduce the fiber vibration frequency, and promote the uniformity and stability of the yarn.

[0014] Please see Figure 1 and Figure 2 This utility model provides a microfiber spinneret diameter-changing device for a microfiber die, including a spinneret 1. The spinneret 1 is composed of a first circular body 11 and a second circular body 12. The diameter of the second circular body 12 is smaller than that of the first circular body 11. The diameter-changing device also includes a collar 2. The collar 2 has a mounting hole 21 for mounting the spinneret 1. The mounting hole 21 is composed of a first fitting hole 211 and a second fitting hole 212. When the spinneret 1 is installed in the mounting hole 21, the first circular body 11 is located in the first fitting hole 211, and the second circular body 12 is located in the second fitting hole 212.

[0015] When using a small spinneret 1 on a large production component, select a collar 2 that matches the large production component and install the small spinneret 1 on the mounting hole 21 of the collar 2.

[0016] By designing a variable-diameter collar 2, a small-sized spinneret 1 can be used on a large-sized assembly after being assisted by a large variable-diameter collar 2. This reduces the need for requisitioning spinnerets 1 and its single-use application. The collar 2 concentrates the spinneret holes in the center of the spinneret 1, increasing the distance between the fiber and the side blower box. This is especially beneficial for products with porous single-fiber fine denier filaments. Increasing the distance between the fiber and the side blower box can reduce the wind speed around the fiber and lower the fiber vibration frequency, which is conducive to the uniformity and stability of the yarn.

[0017] Specifically, the second circular body 12 has a positioning groove 3 on its side wall, and the inner wall of the second fitting hole 212 is connected to a positioning pin 4 that matches the positioning groove 3. When the spinneret 1 is installed in the collar 2, the positioning pin 4 is located in the positioning groove 3.

[0018] Specifically, the first circular body 11 and the first fitting hole 211 are in a transitional fit. This transitional fit improves the installation accuracy of the spinneret 1 and facilitates the assembly and disassembly of the spinneret 1.

[0019] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
