Description

Technical Field

[0001] This invention belongs to the field of textile technology, specifically relating to an integrated device for four-way elastic coated yarn air-jet spinning. Background Technology

[0002] Fabric is the material used to make clothing. As one of the three essential elements of clothing, fabric not only interprets the style and characteristics of clothing, but also directly influences the color and shape of the garment. In the vast world of clothing, fabrics are diverse and constantly evolving. Four-way stretch is a popular fabric product on the market. Its excellent elasticity makes it ideal not only for fashionable women's casual wear but also for trendy trousers. When worn, it not only makes the wearer feel relaxed and natural but also exudes style.

[0003] The current market for the production and processing of four-way elastic requires air-jet spinning, a technology that uses high-speed airflow to stretch polymer melt or solution into fibers. The spun fibers are then coated, with machine-coated or empty-coated options available as needed, to form a composite structure that improves strength or other properties.

[0004] However, when the existing four-sided elastic is produced and processed, the material transfer loss and time delay of the traditional segmented production process greatly improve the production efficiency. Moreover, the spatial layout of each process is relatively loose, the length of the yarn path is long, the yarn will be subjected to a lot of friction when it travels, the yarn breakage rate is high, and the stability of the production process needs to be improved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an integrated device for four-sided elastic coated yarn air jet spinning.

[0006] The technical solution adopted to solve the above technical problems is: a four-sided elastic coated yarn air jet spinning integrated device, including a base, a vertical plate and a mounting frame are fixed on the top of the base, a number of bearing holes are opened horizontally on the top of the mounting frame, and connecting seats are symmetrically arranged on both sides of the top of the mounting frame. A multi-element air jet spinning component for realizing the spinning of different fibers and an anti-precipitation component for preventing the spinning solution from settling are installed above the mounting frame and the base. The front side of the upright plate is fixedly installed from bottom to top with an adjustable drafting component for adjusting the tension of different fiber spinning, a yarn stranding component for gathering and pressing the spinning yarn, an air-wrapping mesh nozzle for air-coating the yarn, and a winding component for uniformly winding the wrapped yarn. Several adjustable drafting components are arranged horizontally. The side wall of the base is provided with a drive device for coordinating the operation of the anti-settling component, the multi-electro-jet spinning component, and the winding component.

[0007] Furthermore, the multi-electro-jet spinning assembly includes a spinning unit and a cross-flow air pump fixed to the upper surface of the base, a metering pump fixed to the upper surface of the mounting frame, a liquid storage tank fixed in the bearing hole, a receiving roller rotatably mounted through the inner side wall of the base, and a high-voltage electrostatic generator fixed to the outer side wall of the base. The metering pump, spinning unit, and liquid storage tank correspond to the position and number of the adjustable drafting assembly. The cross-flow air pump is connected to the multi-electro-jet spinning assembly through a split air supply pipe. The bottom of the liquid storage tank is connected to... The inlets of adjacent metering pumps are connected in a continuous manner. The metering pumps and adjacent spinning units are connected in a continuous manner through a micro-control valve. The receiving roller is located directly above the spinning unit. The metal part of the spinning unit and one end of the receiving roller are respectively connected to the positive and negative terminals of the high-voltage electrostatic generator through wires. Several partition rings are fixedly fixed at equal intervals on the side wall of the receiving roller. The top of the liquid storage tank is connected to an inlet pipe, and the top of the inlet pipe is threaded with a cap. A filter screen is fixedly installed in the outlet hole at the bottom of the liquid storage tank.

[0008] Furthermore, the spinning unit includes an air chamber connected to the gas distribution pipe and a spinneret connected to the precision control valve. The bottom end of the spinneret and the top end of the air chamber are fixedly connected by a connector. An air jet pipe is vertically installed in the middle of the connector. The precision control valve is lower than the upper end face of the air jet pipe.

[0009] The above technical solution enables simultaneous spinning of multiple fibers, meeting the diverse production needs of composite four-way elastic materials. The combination of a metering pump and a precision control valve achieves high-precision regulation of the spinning solution supply. Combined with a high-voltage electrostatic generator to assist in the spinning process, this effectively improves the uniformity of filament fineness. A filter screen removes impurities from the spinning solution, preventing blockage of the spinneret's micropores, which could lead to uneven or even interrupted filament output, affecting fiber continuity. A cap seals the storage tank, preventing solvent evaporation and maintaining a stable solution concentration during spinning.

[0010] Furthermore, the anti-sedimentation component includes a transmission rod that is laterally and rotatably connected to the connecting seat, and a fixing frame fixed to the inner side wall of the storage tank. Several bevel gears are equidistantly sleeved and fixed to the side wall of the transmission rod. A rotating shaft is vertically and rotatably connected to the center of the fixing frame. The top of each rotating shaft passes through the storage tank and is fixedly connected to a bevel gear. Each bevel gear meshes with an adjacent bevel gear. A forward spiral stirring blade and a stirring rod are fixedly connected to the outer side wall of the rotating shaft. A reverse spiral stirring blade is welded and fixed to the outer side of the forward spiral stirring blade through the stirring rod. Scrapers are welded and fixed to both ends of the stirring rod, and a cleaning brush is fixedly connected to the bottom end of the scraper.

[0011] Through the above technical solution, the meshing transmission of bevel gears drives the rotating shafts in each liquid storage tank to rotate, which in turn drives the forward spiral stirring blades, reverse spiral stirring blades, stirring rods, scrapers, and cleaning brushes to rotate synchronously. The rotation of the forward and reverse spiral stirring blades forms a cross flow field, breaking the tendency of solution stratification and preventing precipitation in the spinning solution. The scraper continuously scrapes the inner wall of the liquid storage tank to reduce solution residue, and the cleaning brush cleans the filter screen to prevent particles from clogging the filter screen and affecting the smoothness of solution delivery. This ensures the stable performance of each batch of spinning solution, which directly affects the strength and elasticity of the final product.

[0012] Furthermore, the adjustable stretching assembly includes a frame one fixed to the front wall of the upright plate. A roller one is rotatably connected to the inner side wall of the frame one. Side plates are symmetrically arranged at the front end of the frame one. A top plate is fixed to the top of the side plate. A rotating frame is rotatably connected to the upper surface of the top plate. A guide traction wheel is rotatably connected to the inner side wall of the rotating frame. A lifting plate is arranged between the two side plates. A rotating frame is arranged below the lifting plate. Two limiting rods are fixed to the top of the rotating frame. A stop block is fixed to the top of the limiting rods through the lifting plate. Springs are wound around the outer walls of the limiting rods. Two roller two are rotatably connected to the inner side wall of the rotating frame. An adjustment mechanism for adjusting the height of the lifting plate is provided inside the frame one.

[0013] With the above technical solution, when the fiber filaments at the corresponding positions are pulled and stretched, the fiber filaments are pulled out from the receiving roller and pass through the top of roller one, the bottom of roller two, and the top of the guide traction wheel. The spring-wrapped limiting rod can automatically make fine adjustments according to the force on the filaments to avoid filament breakage or loosening caused by sudden tension changes. The guide traction wheel rotates according to the direction of traction above the fiber filaments, so that the guide traction wheel rolls in the opposite direction of traction, which reduces the length of the fiber filaments' travel path and the risk of friction, and reduces the filament breakage rate.

[0014] Furthermore, the adjustment mechanism includes a movable groove formed in the side wall of the side plate, the side wall of the lifting plate is slidably connected to the inner side wall of the movable groove, an adjusting screw is rotatably connected through the inner wall of the movable groove, a knob is fixedly connected to the top of the adjusting screw, the side wall of the adjusting screw is threadedly connected to the top of the lifting plate, and the outer wall of the side plate is provided with scale lines perpendicular to the movable groove.

[0015] The above technical solution allows for the adjustment of tension to match the fiber filaments of the same fineness, with a wide range of compatibility. This ensures that even fibers of insufficient fineness can be adjusted to their optimal state before empty packaging, thereby improving the finished product quality of four-way elastic coated yarn.

[0016] Furthermore, the thread stranding assembly includes a frame two fixed to the front wall of the upright plate. Positioning and pressing rollers are rotatably connected to the inner walls on both sides of the frame two. A sliding groove is laterally opened on the inner wall of the rear side of the frame two. A bidirectional lead screw is rotatably connected to the inner walls on both sides of the sliding groove. A knob two is fixedly connected to one end of the bidirectional lead screw. A symmetrically arranged displacement frame is threaded through the side wall of the bidirectional lead screw. Clamping rollers are rotatably connected to the inner walls of the front and rear sides of the displacement frame.

[0017] Through the above technical solution, the traction thread passes under the positioning and pressing roller, which further compacts the fiber filaments, providing a flat base for subsequent coating. By driving the bidirectional screw through the knob, the clamping roller on the displacement frame moves relative to each other, which can symmetrically adjust the spacing and pressure of multiple fiber filaments, ensuring that the twisted filament bundle structure is tight and free of fuzz.

[0018] Furthermore, the winding assembly includes a support frame one and a support frame two fixed to the front wall of the upright plate. The support frame one is located below the support frame two. The inner side wall of the support frame one is rotatably connected to a reciprocating winding screw, and the inner side wall of the support frame two is rotatably connected to a winding drum. Both the reciprocating winding screw and the winding drum have an extension rod at the same end.

[0019] Through the above technical solution, the drive device drives the take-up drum and the reciprocating winding screw to rotate synchronously. The groove of the reciprocating winding screw pushes the covering yarn to move back and forth along the axial direction of the take-up drum, avoiding the shoulder phenomenon caused by unidirectional winding and ensuring the winding quality.

[0020] Furthermore, the driving device includes a motor fixed to the outer wall of the base, a driven synchronous pulley one fixed to one end of the transmission rod, and a driven synchronous pulley two fixed to one end of the extension rod. The output end of the motor is fixedly connected to one end of the receiving roller. Two main synchronous pulleys are fixedly connected to the outer wall of the output end of the motor. One of the main synchronous pulleys is connected to the driven synchronous pulley one via a synchronous belt, and the other main synchronous pulley is connected to the driven synchronous pulley two via a synchronous belt.

[0021] The above technical solution drives the receiving roller and the main synchronous wheel to rotate, thereby driving the anti-settling component and the winding component to operate synchronously, ensuring that the line speed of each process is strictly synchronized, and avoiding excessive stretching or accumulation of the yarn.

[0022] The beneficial effects of this invention are as follows: (1) By setting up a multi-electro-jet spinning assembly, an adjustable drawing assembly, a yarn twisting assembly, an air-wrapped mesh nozzle, and a winding assembly, the six core processes of multi-electro-jet spinning, anti-settling, drawing control, yarn twisting, air wrapping, and winding are integrated into the same platform. The integrated design avoids material transfer losses and time delays in traditional segmented production, greatly improves production efficiency, and significantly improves the uniformity, elasticity, and package quality of the product. It is especially suitable for the production of high-end functional fibers such as four-way elastic coated yarn. At the same time, the compact spatial layout of each process reduces the length of the yarn travel path and the risk of friction, reduces the yarn breakage rate, and ensures the stability of the production process. (2) By setting up anti-precipitation components, caps, and filters, the caps seal the storage tank to prevent solvent evaporation and maintain the stability of solution concentration. The filters filter impurities in the spinning solution to prevent clogging of the micropores of the spinneret, which could lead to uneven or even interrupted yarn output. The anti-precipitation components break the layering trend of the solution in each tank to prevent precipitation in the spinning solution. The cleaning brush cleans the filter screen to prevent particles from clogging the filter screen and ensure that the performance of each batch of spinning solution is stable, which directly affects the strength and elasticity of the final product. (3) By setting the drive device, the anti-settling component and the winding component are driven to run synchronously, ensuring that the speed of each process line is strictly synchronized, avoiding excessive stretching or accumulation of the yarn, and a single power source enables the operation of multiple components, reducing the cost of using the equipment and making maintenance convenient.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] like Figures 1-10As shown, an integrated air-jet spinning device for four-sided elastic coated yarn in this embodiment includes a base 1, a vertical plate 2 and a mounting frame 4 fixed on the top of the base 1, a plurality of bearing holes 401 are opened horizontally on the top of the mounting frame 4, and connecting seats 402 are symmetrically arranged on both sides of the top of the mounting frame 4. A multi-element air-jet spinning component 3 for realizing the spinning of different fibers and an anti-precipitation component 5 for preventing the precipitation of spinning solution are installed above the mounting frame 4 and the base 1. The front side of the upright plate 2 is fixedly installed from bottom to top with an adjustable drafting assembly 6 for adjusting the tension of different fibers, a yarn stranding assembly 7 for gathering and pressing the yarn together, an air-coating mesh nozzle 8 for air-coating the yarn, and a winding assembly 9 for uniformly winding the coated yarn. Several adjustable drafting assemblies 6 are arranged horizontally. The side wall of the base 1 is equipped with a drive device 10 for coordinating the operation of the anti-settling assembly 5, the multi-electro-jet spinning assembly 3, and the winding assembly 9. The device integrates six core processes—multi-electro-jet spinning, anti-settling, drafting control, yarn stranding, air-coating, and winding—on the same platform, forming a continuous production line of "spinning—drafting—stretching—coating—winding." The integrated design avoids material transfer losses and time delays in traditional segmented production, significantly improving production efficiency. At the same time, the compact spatial layout of each process reduces the length of the yarn travel path and the risk of friction, reduces the yarn breakage rate, and ensures the stability of the production process. The multi-electro-jet spinning assembly 3 includes a spinning unit 301 fixed to the upper surface of the base 1, a cross-flow air pump 302, a metering pump 304 fixed to the upper surface of the mounting frame 4, a liquid storage tank 305 fixed in the bearing hole 401, a receiving roller 307 rotatably mounted through the inner wall of the base 1, and a high-voltage electrostatic generator 309 fixed to the outer wall of the base 1. The metering pump 304, spinning unit 301, and liquid storage tank 305 correspond to the position and number of the adjustable drafting assembly 6. The cross-flow air pump 302 is connected to the multi-electro-jet spinning assembly 3 through a split air supply pipe 303. The bottom of each liquid storage tank 305 is connected to the inlet of the adjacent metering pump 304. The metering pump 304 is connected to the adjacent spinning unit 301 through a precision control valve 306. The receiving roller 307 is located directly above the spinning unit 301. The metal part of the spinning unit 301 and one end of the receiving roller 307 are respectively connected to the positive and negative poles of the high voltage electrostatic generator 309 through wires 310. Several partition rings 308 are fixedly connected at equal intervals on the side wall of the receiving roller 307. The top of the liquid storage tank 305 is connected through a liquid inlet pipe 3051. The top of the liquid inlet pipe 3051 is threadedly connected to a cap 3052. A filter screen 3053 is fixedly connected in the liquid outlet hole at the bottom of the liquid storage tank 305. The spinning unit 301 includes an air chamber 3011 that is connected through a diversion air supply pipe 303 and a spinneret 3013 that is connected through a precision control valve 306. The bottom end of the spinneret 3013 and the top end of the air chamber 3011 are fixedly connected through a connector 3012. A jet pipe 3014 is vertically installed in the middle of the connector 3012. The precision control valve 306 is lower than the upper end face of the jet pipe 3014. During operation, spinning solutions of different fibers are injected into each storage tank 305 through the inlet pipe 3051, and a cap 3052 is screwed into the inlet pipe 3051. The spinning solutions in the storage tank 305 are fed into the corresponding spinnerets 3013 at the same speed by each metering pump 304 in the same row. Each spinning unit 301 controls the solution flow rate according to the characteristics of the fiber solution through the micro-control valve 306. Then, the cross-flow air pump 302 inputs air into each air chamber 3011 through the split air supply pipe 303. The airflow is sprayed upward through the jet pipe 3014. The spinning solution forms a hollow solution protrusion at the upper end of the spinneret 3013. The high-voltage electrostatic generator 309 is turned on, and a high-voltage electric field is formed between the spinneret 3013 and the receiving roller 307. The hollow solution protrusion is stretched by electrostatic force to form nanofibers. The driving device 10 drives the receiving roller 307 to rotate, and synchronously winds and receives different nanofibers. It can simultaneously spin multiple fibers, meeting the diverse production needs of composite four-way elastic materials. The combination of metering pump 304 and precision control valve 306 enables high-precision regulation of the spinning solution supply. Combined with the high-voltage electrostatic generator 309 to assist in the spinning process, it effectively improves the uniformity of filament fineness. Filter screen 3053 filters impurities in the spinning solution, preventing blockage of the spinneret's micropores, which could lead to uneven or even interrupted filament output, affecting fiber continuity. Cap 3052 seals the storage tank 305, preventing solvent evaporation and maintaining a stable solution concentration during spinning. The anti-sedimentation component 5 includes a transmission rod 501 that is laterally and rotatably connected to the connecting seat 402, and a fixing frame 503 fixed to the inner side wall of the storage tank 305. Several bevel gears 502 are equidistantly sleeved and fixed to the side wall of the transmission rod 501. A rotating shaft 505 is vertically and rotatably connected to the center of the fixing frame 503. Each top of the rotating shaft 505 passes through the storage tank 305 and is fixedly connected to a bevel gear 504. Each bevel gear 502 meshes with an adjacent bevel gear 504. A forward spiral stirring blade 506 and a stirring rod 508 are fixedly connected to the outer side wall of the rotating shaft 505. A reverse spiral stirring blade 507 is welded and fixed to the outer side of the forward spiral stirring blade 506 via the stirring rod 508. Scrapers 509 are welded and fixed to both ends of the stirring rod 508, and a cleaning brush 510 is fixedly connected to the bottom end of the scraper 509. The device operates... At the same time, the drive device 10 drives the transmission rod 501 to rotate each bevel gear 502. Through the meshing transmission of the second bevel gear 504, the rotating shaft 505 in each liquid storage tank 305 is rotated, which drives the forward spiral stirring blade 506, the reverse spiral stirring blade 507, the stirring rod 508, the scraper 509, and the cleaning brush 510 to rotate synchronously. The rotation of the forward spiral stirring blade 506 and the reverse spiral stirring blade 507 forms a cross flow field, which breaks the tendency of solution stratification and avoids precipitation of the spinning solution. The scraper 509 continuously scrapes the inner wall of the liquid storage tank 305 to reduce solution residue. The cleaning brush 510 cleans the filter screen 3053 to prevent particles from clogging the filter screen 3053 and affecting the smoothness of solution delivery. This ensures the stable performance of each batch of spinning solution, which directly affects the strength and elasticity of the final product. The adjustable stretching assembly 6 includes a frame 601 fixed to the front wall of the upright plate 2. A roller 602 is rotatably connected to the inner wall of the frame 601. Side plates 603 are symmetrically arranged at the front end of the frame 601. A top plate 604 is fixedly connected to the top of the side plates 603. A rotating frame 605 is rotatably connected to the upper surface of the top plate 604. A guide traction wheel 606 is rotatably connected to the inner wall of the rotating frame 605. A lifting plate 607 is provided between the two side plates 603. A rotating frame 608 is provided below the lifting plate 607. Two limiting rods 609 are fixedly connected to the top of the rotating frame 608. A stop block 611 is fixedly connected to the top of the limiting rods 609 through the lifting plate 607. Springs 610 are wound around the outer walls of the limiting rods 609. Two rollers 612 are rotatably connected to the inner wall of the rotating frame 608. The body 601 is equipped with an adjustment mechanism for adjusting the height of the lifting plate 607. When the fiber filament at the corresponding position is pulled and stretched, the fiber filament is pulled out from the receiving roller 307 and passes through the top of roller 1 602, the bottom of roller 2 612 and the top of the guide traction wheel 606. The limiting rod 609 wrapped by the spring 610 can automatically fine-tune according to the force on the fiber filament to avoid fiber breakage or loosening caused by sudden tension changes. The guide traction wheel 606 rotates according to the direction of the traction above the fiber filament, so that the guide traction wheel 606 rolls in the opposite direction of traction, which reduces the length of the fiber filament's travel path and the risk of friction, reduces the fiber breakage rate, ensures the stability of the production process, guides the fiber filament to smoothly enter the next process, reduces offset error, makes the stretching ratio of different batches of products consistent, and significantly improves the strength CV value of the finished product. The adjustment mechanism includes a movable groove 613 on the side wall of the side plate 603. The side wall of the lifting plate 607 is slidably connected to the inner side wall of the movable groove 613. An adjusting screw 614 is rotatably connected through the inner wall of the movable groove 613. A knob 616 is fixedly connected to the top of the adjusting screw 614. The side wall of the adjusting screw 614 is threadedly connected to the top of the lifting plate 607. The outer wall of the side plate 603 is vertically provided with a scale line 615 along the movable groove 613. When stretching fibers of different fineness, the adjusting screw 614 can be rotated by the knob 616. The height of the lifting plate 607 can be precisely adjusted by observing the scale line 615, which drives the roller 612 to move up and down. The tension can then be adjusted according to the fiber of the same fineness. The range of adaptability is wide, ensuring that fibers of insufficient fineness can be adjusted to the optimal state before empty wrapping, thus improving the finished product quality of four-way elastic coated yarn. The thread stranding assembly 7 includes a frame 701 fixed to the front wall of the upright plate 2. Positioning and pressing rollers 702 are rotatably connected to the inner walls of both sides of the frame 701. A sliding groove 7011 is laterally opened on the inner wall of the rear side of the frame 701. A bidirectional lead screw 705 is rotatably connected to the inner walls of both sides of the sliding groove 7011. A knob 706 is fixedly connected to one end of the bidirectional lead screw 705. A symmetrically arranged displacement frame 703 is threaded through the side wall of the bidirectional lead screw 705. Clamping rollers 704 are rotatably connected to the inner walls of both the front and rear sides of the displacement frame 703. The pulled thread passes through the fixed... Below the positioning pressing roller 702, the positioning pressing roller 702 further compacts the fiber filaments, providing a flat base for subsequent coating. By driving the bidirectional lead screw 705 through the knob 706, the clamping roller 704 on the displacement frame 703 moves relative to each other, which can symmetrically adjust the spacing and pressure of multiple fiber filaments, ensuring that the twisted filament bundle structure is tight and free of fuzz. The twisted filaments pass through the empty wrapping mesh nozzle 8, which uses the airflow diffusion principle to uniformly wrap the twisted fiber filaments 360°, giving the product better elastic recovery rate and wear resistance. The winding assembly 9 includes a first support frame 901 and a second support frame 903 fixed to the front wall of the upright plate 2. The first support frame 901 is located below the second support frame 903. A reciprocating winding screw 902 is rotatably connected to the inner side wall of the first support frame 901, and a winding drum 904 is rotatably connected to the inner side wall of the second support frame 903. An extension rod 905 is provided at the same end of both the reciprocating winding screw 902 and the winding drum 904. The end of the covering yarn passes through the groove of the reciprocating winding screw 902 and is fixed in place. When the covered yarn is wound, the drive device 10 drives the winding drum 904 and the reciprocating winding screw 902 to rotate synchronously. The groove of the reciprocating winding screw 902 pushes the covered yarn to move back and forth along the axial direction of the winding drum 904, avoiding the shoulder phenomenon caused by unidirectional winding and ensuring the winding quality. The extension rod 905 connects the same end of the two components and is uniformly driven by the drive device 10 to ensure the matching of linear speeds, and the winding surface is flat and tight, making it less likely to fall apart when unwinding. The drive unit 10 includes a motor 1001 fixed to the outer wall of the base 1, a driven synchronous pulley 1004 fixed to one end of the transmission rod 501, and a driven synchronous pulley 2 1005 fixed to one end of the extension rod 905. The output end of the motor 1001 is fixedly connected to one end of the receiving roller 307. Two main synchronous pulleys 1002 are fixedly connected to the outer wall of the output end of the motor 1001. One main synchronous pulley 1002 is connected to the driven synchronous pulley 1004 via a synchronous belt 1003, and the other main synchronous pulley 1002 is connected to the driven synchronous pulley 1004 via a synchronous belt. 1003 is connected to the secondary synchronous pulley 1005. When the device is running, the motor 1001 drives the receiving roller 307 and the main synchronous pulley 1002 to rotate. Through the two synchronous belts 1003, the secondary synchronous pulley 1004 and the secondary synchronous pulley 1005 are driven to rotate synchronously. This drives the anti-settling component 5 and the winding component 9 to operate synchronously, ensuring that the line speed of each process is strictly synchronized, avoiding excessive stretching or accumulation of the yarn. A single power source enables the operation of multiple components, reducing the operating cost of the equipment and making maintenance convenient.

[0027] The working principle of this embodiment is as follows: In use, spinning solutions of different fibers are injected into each storage tank 305 through the inlet pipe 3051, and the cap 3052 is screwed into the inlet pipe 3051. The spinning solution in the storage tank 305 is input into the corresponding spinneret 3013 through each metering pump 304 in the same row. Then, the cross-flow air pump 302 inputs air into each air chamber 3011 through the split air supply pipe 303. The airflow is sprayed upward through the jet pipe 3014. The spinning solution forms a hollow solution protrusion at the upper end of the spinneret 3013. The high-voltage electrostatic generator 309 is turned on, and a high-voltage electric field is formed between the spinneret 3013 and the receiving roller 307. The hollow solution protrusion is stretched by electrostatic force to form nanofibers. The motor 1001 drives the receiving roller 307 to rotate, and the different nanofibers are synchronously wound and received. At the same time, the drive device 10 drives the transmission rod 501 to rotate each bevel gear 502. Through the meshing transmission of the second bevel gear 504, it drives the rotating shaft 505 in each liquid storage tank 305 to rotate, which drives the forward spiral stirring blade 506, the reverse spiral stirring blade 507, the stirring rod 508, the scraper 509, and the cleaning brush 510 to rotate synchronously. The rotation of the forward spiral stirring blade 506 and the reverse spiral stirring blade 507 forms a cross flow field, which breaks the tendency of solution stratification, avoids precipitation in the spinning solution, and ensures the stable performance of each batch of spinning solution. Next, the fiber is drawn out from the receiving roller 307, passing through the top of roller 1 602, the bottom of roller 2 612, and the top of guide traction wheel 606. The limiting rod 609 wrapped by spring 610 can automatically make fine adjustments according to the force on the fiber. The guide traction wheel 606 rotates according to the direction of the traction above the fiber, reducing the length of the fiber's travel path and the risk of friction, and guiding the fiber smoothly into the next process. When stretching to adapt to fibers of different fineness, the adjusting screw 614 can be rotated by knob 1 616, and the height of the lifting plate 607 can be precisely adjusted in conjunction with the observation scale line 615, thereby adjusting the tension to match the fiber of the same fineness. The traction fiber passes under the positioning and pressing roller 702, which further compacts the fiber. The two-way lead screw 705 is driven by the knob 706, which drives the clamping roller 704 on the displacement frame 703 to move relative to each other. The spacing and pressure of multiple fiber filaments can be symmetrically adjusted to ensure that the twisted fiber bundle structure is compact and free of fuzz. The twisted fiber filaments pass through the air-wrapped mesh nozzle 8 to air-encapsulate the fiber filaments. When the covered yarn is wound up, the drive device 10 drives the winding drum 904 and the reciprocating winding screw 902 to rotate synchronously. The groove of the reciprocating winding screw 902 pushes the covered yarn to move back and forth along the axial direction of the winding drum 904. The winding drum 904 winds up the yarn to avoid the shoulder phenomenon caused by unidirectional winding and to ensure the winding quality. It solves key problems of traditional spinning equipment such as "dispersed process, solution sedimentation, uncontrolled tension, and uneven coating". While improving production efficiency, it significantly improves the uniformity, elasticity and package quality of products, and is especially suitable for the production of high-end functional fibers such as four-way stretch coated yarn.
