Abstract
Description
Technical Field
[0001] This utility model relates to the field of fiber manufacturing equipment, and in particular to a cored wire forming device. Background Technology
[0002] The pleated filter screen in air conditioning filters is made of interwoven fibers. These fibers are typically manufactured by pressing the fiber material into a spinneret using an extruder, then extruding the fibers and allowing them to solidify. However, existing spinneret technology has significant limitations, only able to spin out single fibers and unable to produce core-spun fibers with special structures and properties. Core-spun fibers mainly consist of a core fiber and an outer sheath fiber. This unique structure endows core-spun yarn with a variety of excellent properties, such as electrical conductivity, multicolor properties, multilayer properties, flame retardancy, and antibacterial properties.
[0003] In the process of improving pleated filter materials, the application of core-spun fibers has become increasingly important. These fibers can achieve one or more of the aforementioned functions, thereby significantly improving the performance and applicability of the filter. For example, conductive core-spun fibers can effectively reduce static electricity buildup, multi-colored core-spun fibers can provide visual identification, multi-layered core-spun fibers can achieve different levels of filtration effects, flame-retardant core-spun fibers can improve the safety of the filter, and antibacterial core-spun fibers can inhibit bacterial growth and improve the hygienic performance of the filter.
[0004] However, existing fiber production equipment cannot meet the demands of core-spun fibers. Traditional spinnerets can only produce fibers with a single structure and cannot process both core and coating materials simultaneously, which severely limits the production and application of core-spun fibers. Furthermore, existing equipment lacks the ability to precisely control and combine core and coating materials, making it difficult to guarantee the quality and performance stability of core-spun fibers.
[0005] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention
[0006] To address the aforementioned problems, the present invention aims to provide a cored fiber forming device that can simultaneously process core materials and coating materials to achieve the production of cored fibers, and can precisely control the combination of core materials and coating materials to ensure the quality and performance stability of cored fibers.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] This application provides a cored wire forming apparatus, the technical solution of which is as follows: It includes a spinneret, a first feeding assembly for forming the cored wire, and a second feeding assembly for forming the cored wire; the spinneret has multiple spinneret channels, each spinneret channel including an outer channel and an inner channel; the end of the first feeding assembly is connected to the outer channel on the spinneret, and a through hole is formed on the side of the end of the first feeding assembly; the end of the second feeding assembly passes through the through hole and is connected to the inner channel on the spinneret.
[0009] Furthermore, this application also proposes that the spinneret has an outer channel extending through its upper and lower end faces, an inner tube is constructed at the center of the outer channel, and an inner channel is formed inside the inner tube; only the upper end of the inner tube is connected to the inner wall of the outer channel through a spiral track; the coating material fed in by the first feeding assembly can be conveyed downward through the spiral track.
[0010] Furthermore, this application also proposes that the end of the second feed assembly is sealed to the sidewall of the through hole.
[0011] Furthermore, this application also proposes that the first feeding assembly includes a first feeding pipe and a first extrusion zone connected to the first feeding pipe; the second feeding assembly includes a second feeding pipe and a second extrusion zone connected to the second feeding pipe; the downstream of the first extrusion zone is connected to the outer channel of each spinneret channel on the spinneret, and the downstream of the second extrusion zone is connected to the inner channel of each spinneret channel on the spinneret.
[0012] As described above, the core-spun yarn forming apparatus provided in this application includes a spinneret, a first feeding assembly for forming the coated yarn, and a second feeding assembly for forming the core yarn. The spinneret has multiple spinneret channels, each including an outer channel and an inner channel. The end of the first feeding assembly is connected to the outer channel on the spinneret, and a through hole is formed on the side of the end of the first feeding assembly. The end of the second feeding assembly passes through the through hole and connects to the inner channel on the spinneret. This design allows the apparatus to simultaneously process the core material and the coating material, realizing the production of core-spun fibers. Furthermore, by controlling the first and second feeding assemblies separately, the combination of the core material and the coating material can be precisely controlled, thereby ensuring the quality and performance stability of the core-spun fibers.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

Therefore, they should not be construed as limitations on this utility model.
[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.
[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figures 1-5 As shown, this application proposes a cored wire forming apparatus, including a spinneret 1, a first feeding assembly 2 for forming the coated wire, and a second feeding assembly 3 for forming the core wire. The spinneret 1 has multiple spinneret channels, each including an outer channel 10 and an inner channel 11. The end of the first feeding assembly 2 communicates with the outer channel 10 on the spinneret 1, and a through hole 4 is formed on the side of the end of the first feeding assembly 2. The end of the second feeding assembly 3 passes through the through hole 4 and communicates with the inner channel 11 on the spinneret 1. Specifically, each spinneret channel on the spinneret 1 is designed to include an outer channel 10 and an inner channel 11. This structure allows the coated wire and the core wire to be formed through different channels respectively. The end of the first feeding assembly 2 communicates with the outer channel 10, ensuring that the coating material can smoothly enter the outer channel 10. Furthermore, the through hole 4 on the side of the end of the first feeding assembly 2 is designed so that the end of the second feeding assembly 3 can pass through the through hole 4 and communicate with the inner channel 11, thereby realizing the forming of the core wire.
[0024] Therefore, the cored wire forming device of this application can effectively solve the problem that the spinneret 1 in the prior art can only spin out a single fiber. By designing the outer channel 10 and the inner channel 11, the coated wire and the core wire can be formed separately, thereby realizing the production of cored fibers. Compared with the prior art, the technical solution of this application not only improves production efficiency, but also enhances the functionality of the product, such as improvements in conductivity, multicolor, multilayer, flame retardancy, and antibacterial properties.
[0025] In a specific implementation, an outer channel 10 is constructed on the spinneret 1, penetrating its upper and lower end faces. An inner tube 13 is constructed at the center of the outer channel 10, and an inner channel 11 is formed inside the inner tube 13. Only the upper end of the inner tube 13 is connected to the inner wall of the outer channel 10 via a spiral track 14, allowing the coating material fed in by the first feeding assembly 2 to be conveyed downwards via the spiral track 14. This design not only improves the material conveying efficiency but also ensures the uniform distribution of the coating material. Specifically, the design of the outer channel 10 allows the coating material to enter from the upper end face of the spinneret 1 and be conveyed downwards via the spiral track 14, thereby achieving uniform distribution and forming of the coating material. The inner tube 13 not only forms the inner channel 11 but also connects to the spiral track 14 on the inner wall of the outer channel 10 via its upper end, ensuring the stability and continuity of the coating material during the conveying process. As a preferred embodiment, the spiral track 14 can be designed in various forms, such as adjusting the spiral angle, pitch, and track width, to adapt to different coating materials and forming requirements.
[0026] Therefore, the technical solution of this application, by setting a through outer channel 10 and an inner tube 13 on the spinneret 1 and connecting them with a spiral track 14, can achieve the fixed connection and centering of the inner tube 13, and solve the technical problem in the prior art that the spinneret 1 can only spin out a single fiber and cannot obtain core-spun fibers. This technical solution not only realizes the forming of core-spun fibers, but also improves the conveying efficiency and forming quality of the coating material through the optimized design of the spiral track 14. Compared with the prior art, the technical solution of this application has the advantages of simple structure, convenient operation and good forming effect while realizing the forming of core-spun fibers.
[0027] Furthermore, this application proposes that the end of the second feeding assembly 3 is sealed to the sidewall of the through hole 4. Specifically, the sealing of the end of the second feeding assembly 3 to the sidewall of the through hole 4 can prevent the coating material and the core material from mixing or leaking during the conveying process. This sealing design ensures that the coating material and the core material can pass through the outer channel 10 and the inner channel 11 respectively, thereby forming core-spun fibers. As a preferred embodiment, the seal can be achieved by mechanical seals, elastic seals, or other forms of sealing technology. For example, mechanical seals can use metal gaskets or rubber gaskets, while elastic seals can utilize silicone or other elastic materials. Thus, the sealing design of the end of the second feeding assembly 3 to the sidewall of the through hole 4 can effectively solve the technical problem of material mixing during the production of core-spun fibers. This design not only improves the forming quality of the core-spun fibers but also enhances their properties, such as conductivity, multicolor, multilayer distribution, flame retardancy, and antibacterial properties. Compared with the prior art, the technical solution of this application has significant advantages in ensuring material separation and performance improvement.
[0028] Furthermore, this application proposes that the first feeding assembly 2 includes a first feeding pipe 21 and a first extrusion zone 22 connected to the first feeding pipe 21; the second feeding assembly 3 includes a second feeding pipe 31 and a second extrusion zone 32 connected to the second feeding pipe 31; the downstream of the first extrusion zone 22 is connected to the outer channel 10 of each spinneret channel on the spinneret 1, and the downstream of the second extrusion zone 32 is connected to the inner channel 11 of each spinneret channel on the spinneret 1. Specifically, the first feeding pipe 21 and the second feeding pipe 31 are used to transport the coating material and the core material, respectively. The first extrusion zone 22 and the second extrusion zone 32 extrude the transported material to ensure that the material can pass smoothly through the outer channel 10 and the inner channel 11 on the spinneret 1. The downstream of the first extrusion zone 22 is connected to the outer channel 10 of all spinneret channels on the spinneret 1, so that the coating material can be evenly distributed in the outer channel 10 of each spinneret channel. Similarly, the downstream of the second extrusion zone 32 is connected to the inner channel 11 of all spinnerets on the spinneret 1, ensuring that the core material can be evenly distributed in the inner channel 11 of each spinneret. As a preferred embodiment, the first feed pipe 21 and the second feed pipe 31 can employ different materials and structural designs to accommodate different coating materials and core materials. For example, the first feed pipe 21 can be made of a high-temperature resistant material to accommodate the conveying of high-temperature coating materials; the second feed pipe 31 can be made of a corrosion-resistant material to accommodate the conveying of corrosive core materials. Furthermore, the first extrusion zone 22 and the second extrusion zone 32 can employ different extrusion methods, such as mechanical extrusion, hydraulic extrusion, or pneumatic extrusion, to meet the molding requirements of different materials. Thus, through the above technical means, this application can effectively solve the problem in the prior art that the spinneret 1 can only extrude a single fiber and cannot obtain core-spun fibers. Specifically, this application achieves the production of core-spun fibers by setting up a first feed assembly 2 and a second feed assembly 3 to respectively convey coating materials and core materials, and by evenly distributing the materials in the spinneret channels of the spinneret 1 through the extrusion zone. Compared with existing technologies, the technical solution of this application can not only produce core-spun fibers, but also be flexibly adjusted according to different material requirements, resulting in higher production efficiency and a wider range of applications.
