Description

Technical Field

[0001] This utility model relates to the field of spinning devices for ultrafine porous filaments, specifically a spinning device for ultrafine porous filaments. Background Technology

[0002] Due to its excellent properties such as large specific surface area, good air permeability, and lightweight, ultrafine porous yarn is increasingly in demand for applications in textile fabrics, filter materials, and biomedical carriers. The performance of its spinning equipment directly determines the quality of the finished yarn and production efficiency.

[0003] Existing ultrafine porous filament spinning devices have poor separation or coordination between the mixing and conveying structures. A single mixing blade mixes the raw materials, making it difficult to ensure both uniform mixing and stable conveying. Especially when the viscosity of the spinning raw materials is high, problems such as local accumulation of raw materials in the cylinder and uneven conveying thrust can easily occur, leading to frequent blockages or flow interruptions during the raw material conveying process.

[0004] Therefore, it is necessary to design a new type of spinning device for ultrafine porous filaments to solve the above problems. Utility Model Content

[0007] Preferably, the stirring structure includes a drive motor, one end of which is fixedly connected to a rotating shaft, a auger blade is fixedly connected to the rotating shaft, and one end of the rotating shaft is fixedly connected to a conveying shaft, on which a conveying blade is fixedly connected.

[0008] Preferably, a filter plate is fixedly connected to one end of the inner cavity of the cylinder, and the filter plate is provided with a plurality of filter holes, which are evenly distributed on the filter plate.

[0009] Preferably, a spinneret is fixedly connected to one end of the cylinder, and the spinneret is provided with a plurality of spinneret holes evenly distributed.

[0010] Preferably, a conveying pipe is fixedly connected to the side of the cylinder, and a feeding hopper is fixedly connected to one end of the conveying pipe.

[0011] Preferably, a flange is fixedly connected to the side of the spinneret, and air jet holes are evenly provided on the flange along the axis of the spinneret.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the stirring structure works in concert with the auger blades and the conveying blades, which can not only achieve thorough mixing of raw materials, but also stably push the raw materials to the spinneret, reducing the problem of blockage or flow interruption during the raw material conveying process; the filter holes of the filter plate can effectively intercept impurities, reduce the risk of spinneret blockage, and ensure the continuous and stable operation of the device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] All electronic components in this application are controlled by an external controller.

[0021] Example 1 Please refer to Figure 1-5As shown, this utility model provides a spinning device for ultrafine porous yarns, including a support frame 1, on which a cylinder 2 is fixedly connected, providing a closed cavity for the heating, stirring, and conveying of raw materials; a heating ring 3 is fixedly connected to the inner wall of the cylinder 2, and multiple heating rings 3 are evenly distributed along the axial direction of the cylinder 2. When energized, they generate heat to uniformly heat the spinning raw material inside the cylinder 2, causing the raw material to melt or reach the required flow viscosity for spinning; a stirring structure is fixedly connected inside the cylinder 2.

[0022] Specifically, the stirring structure includes a drive motor 4, one end of which is fixedly connected to a rotating shaft 5, and a auger blade 6 is fixedly connected to the rotating shaft 5. A conveying shaft 7 is fixedly connected to the other end of the rotating shaft 5, and a conveying blade 8 is fixedly connected to the conveying shaft 7. The output end of the drive motor 4 is connected to the rotating shaft 5 on the cylinder 2. The auger blade 6 fixed on the rotating shaft 5 rotates with the rotating shaft 5, thoroughly stirring and mixing the spinning raw material in the cylinder 2 to ensure uniform composition. Simultaneously, the end of the rotating shaft 5 near the spinneret 11 is connected to the conveying shaft 7, and the conveying blade 8 on the conveying shaft 7 rotates synchronously, stably pushing the uniformly mixed raw material towards the spinneret 11. Through the coordinated work of the auger blade 6 and the conveying blade 8, the raw material is uniformly mixed.

[0023] The filter plate 9 is fixedly connected to one end of the inner cavity of the cylinder 2. The filter plate 9 is provided with a plurality of filter holes 10, which are evenly distributed on the filter plate 9. The filter holes 10 can intercept impurities that may exist in the raw materials, and prevent impurities from entering the spinneret 11 and clogging the spinneret hole 12 or affecting the quality of the finished yarn.

[0024] Based on the above embodiments, specifically, one end of the cylinder 2 is fixedly connected to a spinneret 11, and the spinneret is uniformly provided with a plurality of spinneret holes 12; the spinneret holes 12 are evenly distributed, and under the action of conveying pressure, the filtered raw material is extruded through the spinneret holes 12 to initially form ultrafine filaments.

[0025] Specifically, a conveying pipe 13 is fixedly connected to the side of the cylinder 2, and a feeding hopper 14 is fixedly connected to one end of the conveying pipe 13; the feeding hopper 14 is used to temporarily store the spinning raw materials to be processed; the conveying pipe 13 connects the feeding hopper 14 and the cylinder 2, and conveys the raw materials in the feeding hopper 14 to the inside of the cylinder 2.

[0026] Specifically, a flange 15 is fixedly connected to the side of the spinneret 11, and air jet holes 16 are evenly provided on the flange 15 along the axis of the spinneret. The flange 15 is fixed to the side of the spinneret 11 and can be used to connect an external air source or other auxiliary devices. The air jet holes 16 are evenly distributed along the axis of the spinneret 11 and are used to eject airflow to stretch and refine the filaments that have just been extruded from the spinneret holes 12, cool and shape them, or help form a porous structure.

[0027] Working principle: The spinning raw material is first temporarily stored in the feed hopper 14 and enters the cylinder 2 through the feed pipe 13. The heating ring 3 on the inner wall of the cylinder 2 is energized and heats up, uniformly heating the raw material to melt it or reach the required flow viscosity for spinning. At the same time, the drive motor 4 of the stirring structure drives the rotating shaft 5 to rotate. The auger blades 6 on the rotating shaft 5 fully stir the molten raw material to ensure uniform composition. The conveying shaft 7 and conveying blades 8 near the spinneret 11 push the uniformly mixed raw material toward the spinneret 11. Under the action of the pushing force, the raw material flows through the filter plate 9. The filter holes 10 on the filter plate 9 intercept impurities in the raw material. The filtered pure raw material is continued to be pushed to the spinneret 11. Under the conveying pressure, it is extruded through the spinneret holes 12 on the spinneret 11 to form ultrafine filaments. At the same time, the air jet holes 16 on the flange 15 spray air, which plays a role in stretching and refining the filament diameter and assisting in the formation of a porous structure.
