Description

Technical Field

[0001] This utility model relates to the field of polyethylene fiber production and processing technology, specifically a melt spinning device for polyethylene fiber production and processing. Background Technology

[0002] Polyethylene fiber is a synthetic fiber material made from polyethylene through melt spinning. It has advantages such as being lightweight, wear-resistant, corrosion-resistant, acid and alkali-resistant, high-temperature resistant, and insulating. Its mechanical strength can be adjusted by the spinning process parameters. It is widely used in textiles, industry, and construction, especially in the production of filter materials, tarpaulins, mesh belts, and sportswear. Polyethylene fiber also has good thermal conductivity, which can quickly dissipate heat and provide a cooling effect. When processing polyethylene fiber, a melt spinning device is needed to melt spin the polyethylene fiber raw material to produce a linear object that can be spun.

[0003] However, in existing melt spinning equipment for polyethylene fiber production and processing, the melted polyethylene fiber raw material tends to adhere to the inner wall of the melting device during use, resulting in incomplete heating of the raw material and affecting the fiber output effect. Furthermore, most existing devices use fixed spinning heads, which is not convenient for operators to arbitrarily change spinning heads of different diameters according to actual spinning needs. Utility Model Content

[0004] The purpose of this utility model is to provide a melt spinning device for the production and processing of polyethylene fibers, so as to solve the problems mentioned in the background art and overcome its technical defects.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a melt spinning device for polyethylene fiber production and processing, including a base plate, two support frames are fixedly connected to the outer surface of the base plate, a melting kettle is fixedly connected to the outer surface of the two support frames, a melting mechanism is provided inside the melting kettle, and a spinning mechanism is fixedly connected to the outer surface of the melting kettle.

[0006] Preferably, the outer surface of the melting vessel is fixedly connected to a feed funnel, and the inner wall of the melting vessel is provided with several heating plates.

[0007] Preferably, the outer surface of the feed funnel is provided with four placement slots, and the interior of the four placement slots is provided with a filter rack.

[0008] Preferably, the melting mechanism includes a mounting frame and two sealed bearings, and a drive motor is fixedly mounted on the outer surface of the mounting frame.

[0009] Preferably, the output end of the drive motor is fixedly connected to a stirring frame, one end of which passes through one of the sealed bearings and extends into the interior of the melting vessel.

[0010] Preferably, one end of the stirring frame is fixedly connected to the inner ring of another sealed bearing, a number of scrapers are fixedly connected to the outer surface of the stirring frame, and a number of temperature sensors are provided on the outer surface of the stirring frame.

[0011] Preferably, the spinning mechanism includes a liquid guide tube, and a control valve is provided inside the liquid guide tube.

[0012] Preferably, the outer surface of the liquid guide tube is threaded with a spinneret, and the spinneret is provided with a heat-resistant sealing ring inside.

[0013] Compared with the prior art, the beneficial effects of this utility model include: The drive motor rotates the stirring rack, and the scraper design effectively prevents the molten polyethylene fiber raw material from adhering to the inner wall of the melting vessel, ensuring uniform heating of the raw material and avoiding local overheating or incomplete heating. This improves melting efficiency and quality. The spinneret is connected by a thread, allowing operators to quickly change to different diameter spinnerets according to actual production needs, adapting to diverse fiber production requirements and improving the equipment's versatility and production flexibility. The heat-resistant sealing ring ensures a tight seal between the spinneret and the liquid guide pipe, preventing leakage of molten polyethylene. Its high-temperature resistance ensures long-term stable operation. A temperature sensor monitors the melting temperature in real time, and combined with the dynamic adjustment of the stirring mechanism, ensures the melting process occurs within the optimal temperature range, avoiding temperature fluctuations that affect fiber quality. This solves the problems of molten polyethylene fiber raw material easily adhering to the inner wall of the melting device, leading to incomplete heating and affecting fiber output, and the inconvenience of using fixed spinnerets that prevent operators from arbitrarily changing to different diameter spinnerets according to actual spinning needs.

[0016] According to one embodiment of the present invention, in conjunction with the appended drawings Figures 1-4 As shown.

[0017] A melt spinning device for polyethylene fiber production and processing includes a base plate 1. Two support frames 2 are fixedly connected to the outer surface of the base plate 1. A melting pot 3 is fixedly connected to the outer surface of the two support frames 2. A feed funnel 6 is fixedly connected to the outer surface of the melting pot 3. Several heating plates 7 are provided on the inner wall of the melting pot 3. Four placement slots 8 are opened on the outer surface of the feed funnel 6. A filter frame 9 is provided inside the four placement slots 8. The feed funnel 6 is used to add polyethylene raw materials. Its large opening facilitates the input of raw materials. At the same time, the filter frame 9 can pre-filter impurities to prevent clogging of the melting pot 3. The heating plates 7 provide a stable heat source to melt the raw materials. The placement slots 8 are used to place the filter frame 9. The filter frame 9 filters impurities in the polyethylene raw materials to prevent impurities from entering the melting pot 3 and causing the spinneret 503 to become clogged or the fiber quality to decline.

[0018] In this embodiment, the melting vessel 3 is equipped with a melting mechanism 4. The melting mechanism 4 includes a mounting frame 401 and two sealed bearings 402. A drive motor 403 is fixedly mounted on the outer surface of the mounting frame 401. A stirring frame 404 is fixedly connected to the output end of the drive motor 403. One end of the stirring frame 404 passes through one of the sealed bearings 402 and extends into the interior of the melting vessel 3. One end of the stirring frame 404 is fixedly connected to the inner ring of the other sealed bearing 402. Several scrapers 405 are fixedly connected to the outer surface of the stirring frame 404. Several temperature sensors 406 are provided on the outer surface of the stirring frame 404. The mounting bracket 401 fixes the drive motor 403 and the sealed bearing 402, providing mechanical support to ensure the stable rotation of the stirring rack 404. The sealed bearing 402 supports the rotation of the stirring rack 404 and prevents the molten liquid from leaking. The drive motor 403 provides power to drive the stirring rack 404 to rotate, so that the raw materials are heated evenly. The scraper 405 scrapes off the raw materials adhering to the inner wall of the melting vessel 3 to avoid the accumulation of raw materials, which may cause uneven heating or affect the melting efficiency. The temperature sensor 406 monitors the temperature inside the melting vessel 3 in real time and feeds it back to the remote control system to ensure that the melting temperature is kept within the optimal range and to avoid overheating or insufficient melting.

[0019] In this embodiment, a spinning mechanism 5 is fixedly connected to the outer surface of the melting vessel 3. The spinning mechanism 5 includes a liquid guide pipe 501, a control valve 502 inside the liquid guide pipe 501, and a spinneret 503 threadedly connected to the outer surface of the liquid guide pipe 501. A heat-resistant sealing ring 504 is provided inside the spinneret 503. The liquid guide pipe 501 delivers molten polyethylene to the spinneret 503. At the same time, the control valve 502 can adjust the flow rate to ensure the stability of the spinning process. The spinneret 503 extrudes the molten polyethylene into fibers. The diameter of the fibers determines their thickness. The fibers can be rotated off the surface of the liquid guide pipe 501 and replaced to meet different production needs. The heat-resistant sealing ring 504 prevents the molten liquid from leaking from the connection between the spinneret 503 and the liquid guide pipe 501, ensuring the safety and stability of the spinning process.

[0020] Working Principle: First, polyethylene fiber raw materials are added to the melting kettle 3 through the feed funnel 6. The filter rack 9 performs preliminary filtration of the raw materials to remove impurities. The heating plate 7 is energized to heat the melting kettle 3, while the drive motor 403 drives the stirring rack 404 to rotate. The scraper 405 continuously scrapes the inner wall of the kettle to prevent raw materials from adhering and ensure uniform heating. The temperature sensor 406 monitors the melting temperature in real time and feeds it back to the cloud control system to dynamically adjust the heating power and maintain the optimal melting state. Molten polyethylene is transported through the liquid guide pipe 501, and the control valve 502 regulates the flow rate to ensure stable feeding. The molten liquid is extruded through the spinneret 503 to form fibers. The diameter of the spinneret 503 can be replaced as needed. Different specifications of spinnerets 503 can be disassembled and installed by threads to adjust the fiber thickness. The heat-resistant sealing ring 504 prevents molten liquid leakage and ensures the safety and continuity of the spinning process. The staff can clean the filter rack 9 or replace the spinneret 503 regularly to ensure long-term efficient operation of the equipment.

[0021] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
