Description

Technical Field

[0001] This utility model relates to the field of spinning processing technology, and in particular to a double-cavity single-spinning assembly. Background Technology

[0002] With the development of materials science and polymer chemistry, spinning equipment is needed when spinning polymers. Spinning technology is used to extrude molten or dissolved polymer materials into long fibers through fine spinnerets by heating and high pressure. It is widely used in the production of synthetic fibers, functional fibers and high-performance materials. As the demand for new functional materials continues to increase, the technology of spinning equipment is constantly being improved to achieve precise control of materials, optimization of fiber structure and improvement of performance.

[0003] Currently, there are various types of spinning equipment on the market, but these devices usually use a four-chamber processing method. The internal material flow path is relatively complex, which can easily lead to uneven pressure distribution within the chamber, thus affecting the heating and extrusion process of the material and reducing the overall production efficiency and spinning quality. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a dual-cavity single-spinning assembly.

[0005] This utility model is achieved by the following technical solution: a double-cavity single-spinning assembly, including a spinning mechanism, an inner melt mechanism and an auxiliary mechanism, wherein the inner melt mechanism is located on one side of the spinning mechanism and the auxiliary mechanism is located on the surface of the spinning mechanism; The spinning mechanism includes a housing, a main feed inlet on one side of the housing, a feed bin fixedly connected to the inner wall of the housing near the main feed inlet, a branch feed inlet on the surface of the feed bin, a connecting pipe fixedly connected to the branch feed inlet away from the main feed inlet, and a blind hole on the surface of the feed bin.

[0006] Through the above technical solution, the material is guided into the feeding hopper through the main feed port and then transported to different channels through the branch feed ports, thereby realizing the diversion and supply of materials, effectively ensuring the uniform distribution of materials during the conveying process, and thus maintaining the stability and balance of the subsequent melt pressure.

[0007] As a further improvement to the above solution, the main feed inlet is located on the right side of the housing, and the branch feed inlet is located at the front end of the blind hole.

[0008] As a further improvement to the above scheme, the number of branch feed ports is set to two, and the two branch feed ports are symmetrically distributed vertically around the feed hopper.

[0009] The above technical solution allows for symmetrically arranged branch feed ports to prevent excessive material accumulation on one side, promoting a more uniform and efficient subsequent heating and extrusion process.

[0010] As a further improvement to the above solution, the internal melt mechanism includes a dual melt pipeline body, an inner cavity is fixedly connected to the inner wall of the dual melt pipeline body, a discharge chamber is fixedly connected to one side of the inner cavity, and a discharge port is opened on one side of the discharge chamber.

[0011] Through the above technical solution, the material can be fully heated and squeezed when passing through the inner cavity of the dual melt pipeline body, thereby ensuring the full plasticization of the material and further optimizing the production process of composite filament.

[0012] As a further improvement to the above solution, one side of the outer shell is fixedly connected to the surface of the dual melt pipeline body.

[0013] As a further improvement to the above solution, the auxiliary mechanism includes a threaded groove, and a locating pin is installed between the outer shell and the dual melt pipeline body.

[0014] Through the above technical solution, the positioning pin makes the connection between the outer shell and the body of the double melt pipeline simpler and more secure, and also facilitates assembly and disassembly, effectively improving the overall maintenance efficiency of the device.

[0015] As a further improvement to the above solution, the threaded groove is formed on the surface of the housing near the main feed inlet.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes the cooperation between the spinning mechanism and the internal melt mechanism. The operator feeds the material into the branch feed ports inside the feeding hopper through the main feed port. The branch feed ports effectively and evenly distribute the material, allowing it to smoothly enter the inner cavity of the dual melt pipeline body. The material is heated and compressed in the inner cavity and finally transported out through the discharge port. Compared to four branch feed ports, the two branch feed ports help to better balance the pressure distribution inside the inner cavity, ensuring uniformity during processing and improving the working efficiency and stability of the device, thereby further improving the overall spinning quality.

[0017] This utility model, by setting up an auxiliary mechanism, ensures the structural stability and modular connectivity of the overall device by fixing the outer shell to the body of the double melt pipeline through positioning pins. The threaded groove facilitates the connection and installation with other devices, thereby further improving the overall practical effect of the device. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0021] Please combine Figure 1-5 The dual-cavity single-spinning assembly of this embodiment includes a spinning mechanism 1, an inner melt mechanism 2, and an auxiliary mechanism 3. The inner melt mechanism 2 is located on one side of the spinning mechanism 1, and the auxiliary mechanism 3 is located on the surface of the spinning mechanism 1. The spinning mechanism 1 includes a housing 11, with a main feed inlet 12 on one side of the housing 11. A feed bin 13 is fixedly connected to the inner wall of the housing 11 near the main feed inlet 12. A branch feed inlet 14 is opened on the surface of the feed bin 13. A connecting pipe 15 is fixedly connected to the side of the branch feed inlet 14 away from the main feed inlet 12. A blind hole 16 is opened on the surface of the feed bin 13. The material is guided into the feed bin 13 through the main feed inlet 12 and conveyed to different channels through the branch feed inlets 14, thereby realizing the diversion and supply of materials, effectively ensuring the uniform distribution of materials during the conveying process, and thus maintaining the stability and balance of the subsequent melt pressure.

[0022] The main feed inlet 12 is located on the right side of the outer casing 11, and the branch feed inlet 14 is located at the front end of the blind hole 16.

[0023] There are two branch feed inlets 14, which are symmetrically distributed around the feed hopper 13. The symmetrical arrangement of the branch feed inlets 14 can prevent the material from accumulating excessively on one side, and promote a more uniform and efficient heating and extrusion process in the subsequent process.

[0024] The inner melt mechanism 2 includes a double melt pipeline body 21. An inner cavity 22 is fixedly connected to the inner wall of the double melt pipeline body 21. A discharge cavity 23 is fixedly connected to one side of the inner cavity 22. A discharge port 24 is opened on one side of the discharge cavity 23. When the material passes through the inner cavity 22 inside the double melt pipeline body 21, it can be fully heated and squeezed, thereby ensuring that the material is fully plasticized and further optimizing the production process of composite yarn.

[0025] One side of the outer casing 11 is fixedly connected to the surface of the dual melt pipeline body 21.

[0026] The auxiliary mechanism 3 includes a threaded groove 31, and a positioning pin 32 is installed between the housing 11 and the dual melt pipeline body 21. The positioning pin 32 makes the connection between the housing 11 and the dual melt pipeline body 21 easier and more secure, and also facilitates assembly and disassembly, effectively improving the overall maintenance efficiency of the device.

[0027] The threaded groove 31 is formed on the surface of the housing 11 near the main feed port 12.

[0028] The implementation principle of the dual-cavity single-spinning assembly in this embodiment is as follows: The operator places the material from the main feed inlet 12 into the branch feed inlets 14 within the feed bin 13. The material is then transported through the connecting pipe 15 to the inner cavity 22 inside the dual melt pipeline body 21. In the inner cavity 22, the material is heated and compressed, and finally pushed to the discharge cavity 23. Through the connecting pipe 15, the material is smoothly transported to its respective inner cavity 22 for processing, thus ensuring that the two inner cavities 22 can operate synchronously without interfering with each other, maintaining uniform pressure within the inner cavity 22. The blind holes 16 not only enhance the aesthetics of the device to a certain extent, but also improve the efficiency of the process by optimizing the layout of the branch feed inlets 14. To improve the overall performance of the device, compared to the setup of four branch feed ports 14, the use of two branch feed ports 14 helps to better balance the pressure distribution inside the inner cavity 22, ensuring uniformity during processing and improving the working efficiency and stability of the device. The final processed composite filament is conveyed out through the discharge port 24, and the outer shell 11 and the dual melt pipeline body 21 are fixed by the positioning pin 32 to ensure the stability of the connection between the two. The threaded groove 31 opened on the outer shell 11 provides a convenient installation method for connecting the device with other equipment. The entire device effectively ensures the fineness uniformity of each bundle of filament after the spinneret, thereby further improving the quality and efficiency of subsequent spinning production.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
