By improving the original nylon spinning process and streamlining the number of equipment used in the original process, the overall failure rate of the device can be effectively reduced and the operation stability of the device can be improved under the premise of ensuring accurate control of the spinning length. When the last fixed-length spinning is ejected from a stacked spinning assembly, the spinning melt residue originally contained in the micropores of the stacked spinning assembly is carried out through the squeezing effect of the gas, effectively avoiding the possibility that the spinning melt residue solidifies and clogs in the stacked spinning assembly, resulting in the need to clean the micropores of the stacked spinning assembly in advance before each start-up.

Description

Technical Field

[0001] The invention relates to the field of textiles, and more specifically to a high-efficiency spinning device for nylon textiles. Background Art

[0002] Nylon, also known as nylon, is the first synthetic fiber in the world. Nylon is a name for polyamide fiber (nylon). The emergence of nylon has given textiles a new look. Its synthesis is a major breakthrough in the synthetic fiber industry and a very important milestone in polymer chemistry. Nylon has a wide range of applications. It is widely used in industry to replace copper and other metals in the manufacture of bearings, gears, pump blades and other parts in machinery, chemical, instrumentation, automobile and other industries. It is mainly used as parachutes and other military fabrics in national defense. It can be blended or purely spun into various medical and knitwear products for civilian use.

[0003] The premise of nylon fabric is to get nylon spinning. The nylon spinning process generally refers to the use of nylon chips, that is, the flaky granulated products obtained by the pelletizing method due to its low melt strength in nylon production are melt-extruded into high-viscosity spinning melt by the screw. After the melt is transported into the spinning box, it is heated to a suitable spinning temperature, and evenly reaches each spinning position through the melt distribution pipe in the box, and then reaches each spinning component after precise metering by the spinning metering pump. After being filtered by the filter material in the component, it is extruded from the spinneret into a thin melt stream. Under the action of the set cooling air cooling and winding stretching, the thin melt stream is cooled and solidified into a certain fineness of the silk strip, and then the primary fiber formed by spinning is subjected to low-multiple drawing and high-temperature heat setting to form civil nylon silk with stable physical and mechanical properties.

[0004] According to the actual market demand, the above process can realize the production of nylon filament and short yarn by changing the spinneret. The spinneret for filament has fewer holes, while the spinneret for short yarn has more holes. However, whether it is nylon filament or short yarn, the above process flow is too long and too many equipments are used, resulting in a high failure rate of the device during long-term use, and it is impossible to accurately control the spinneret length, especially the precise control of the spinneret length of short yarn. After the spinning operation is completed, the traditional spinning equipment cannot clean the micropores of the spinneret in situ, and there will be residual spinning melt in the micropores of the spinneret. The solidified spinning melt residue will clog the spinneret. Therefore, before each start-up, the spinneret needs to be disassembled in advance to clean the micropores of the spinneret, which will delay the progress of the operation. Summary of the invention

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a high-efficiency spinneret for nylon textile. By improving the original nylon spinning process and streamlining the number of equipment used in the original process, the overall failure rate of the device can be effectively reduced and the operation stability of the device can be improved under the premise of ensuring accurate control of the spinning length. When the last fixed-length spinning is ejected from the stacked spinneret assembly, the squeezing effect of the isolation gas is cut off, so that the spinning melt residue originally contained in the micropores of the stacked spinneret assembly can be ejected together as a part of the last fixed-length spinning, and a large amount of spinning melt residue will not be formed in the micropores, causing later coagulation blockage, resulting in the possibility of needing to clean the micropores of the stacked spinneret assembly in advance before each start-up. This in-situ treatment method for the spinning melt residue in the micropores of the stacked spinneret assembly does not require the stacked spinneret assembly to be disassembled and cleaned, and can effectively improve the progress of the operation.

[0007] 2. Technical solution

[0008] To solve the above problems, the present invention adopts the following technical solutions.

[0009] A high-efficiency spinning device for nylon textile, comprising a plurality of laterally evenly arranged spinning tubes, a plurality of said spinning tubes being provided with spiral push rods, a plurality of said spiral push rods being driven by a driving motor and a corresponding gear box, a plurality of said spinning tubes being fixedly mounted with a stacked spinning assembly at the bottom end, a plurality of said spinning tubes being provided with an air supply main pipe on the right side, an air supply device being fixedly mounted at the inlet end of said air supply main pipe, a plurality of air supply branch pipes being fixedly connected to the outer end wall of said air supply main pipe, a plurality of said air supply branch pipes being respectively fixedly mounted on the upper side of the outer end wall of the corresponding spinning tube, an air supply device being provided on the right side of said spinning tubes, a plurality of said air supply device being fixedly mounted at the outlet end of said air supply device, and said air supply device being intermittently opened by a control terminal.

[0010] Furthermore, a collecting bin is provided on the left side of the plurality of spray barrels, a plurality of slide rails are fixedly installed on the inner top end of the collecting bin, an electric telescopic rod is slidably connected to the plurality of slide rails through sliders, an adhesive plate is fixedly installed on the telescopic end of the plurality of electric telescopic rods, an elastic scraper block is adhered to the bottom end of the adhesive plate, a collecting box is fixedly installed on the bottom end of the collecting bin, and after the air supply device is started, the wind blown out by the plurality of high-pressure nozzles can not only cool the ejected spinning, but also, after the last fixed-length spinning is ejected from the stacked spinneret assembly and one stage of spinning operation is completed, not only will spinning melt be formed in the micropores of the stacked spinneret assembly At this time, the gas does not play a role of isolation, but a cleaning role. Through the flushing effect of the gas, the spinning melt residue on the inner wall of the spray tube is blown out from the micropores of the stacked spinneret assembly together with the gas. The wind blown out by the high-pressure nozzle quickly cools the spinning melt residue and blows it to the collecting bin. After being started by the electric telescopic rod, it drives the sliding scraping effect of the adhesive plate and the elastic scraper block on the collecting bin, and quickly scrapes the spinning melt residue into the collecting box for collection and treatment.

[0011] Furthermore, an electrostatic suction plate is fixedly installed at a position parallel to the collecting bin and the high-pressure nozzle, and an electrostatic generator is fixedly installed on the top of the air supply device. The electrostatic generating effect of the electrostatic generator causes the wind blown out from the high-pressure nozzle to carry electrostatic ions, thereby causing the spinning melt residue guided by it to carry electrostatic ions in the process of being blown to the collecting bin, and finally be adsorbed by the electrostatic suction plate installed in the collecting bin, thereby effectively reducing the possibility of the spinning melt residue colliding and sputtering with the collecting bin in the process of being guided by the airflow to the collecting bin, and failing to be collected well.

[0012] Furthermore, a magnetic sheet is bonded to one end of the elastic scraper block away from the electrostatic suction plate. The electrostatic suction plate can not only attract the spinning melt residue with electrostatic ions, but also attract the magnetic sheet. Through the attraction effect of the electrostatic suction plate on the magnetic sheet and the sliding effect of the electric telescopic rod in the slide rail, the lateral squeezing effect of the elastic scraper block on the electrostatic suction plate is finally achieved, thereby improving the scraping effect of the elastic scraper block on the spinning melt residue collected on the electrostatic suction plate and improving the cleaning efficiency.

[0013] Furthermore, the stacked spinneret assembly comprises a connecting shaft, a pair of locking rings, and upper, middle, and lower spinneret single plates stacked one above the other. The upper, middle, and lower spinneret single plates rotate on the connecting shaft, and a pair of locking rings are locked at the upper and lower ends of the connecting shaft by screws. When the micropores on the stacked spinneret assembly are still clogged during long-term use, the operator removes the stacked spinneret assembly from the spinneret, and then removes the pair of locking rings. By removing it from the connecting shaft, the upper spinneret, the middle spinneret and the lower spinneret can be smoothly removed from the connecting shaft, and during the removal process, the solidified spinning melt residue will be peeled off from the upper spinneret, the middle spinneret or the lower spinneret, making it easy to clean it. By transforming the original one-piece structure of the stacked spinneret assembly into an independently detachable stacked structure, the cleaning effect of the spinning melt residue blocked in the stacked spinneret assembly can be effectively improved.

[0014] Furthermore, an electric swivel is installed at the bottom end of the spray barrel, and an electromagnetic locking block is fixedly connected to the lower side of the inner end wall of the spray barrel, and the inner end wall of the electric swivel is fixedly connected to a limit block. The outer end walls of the upper, middle and lower spinneret plates are all provided with locking grooves, and the inner end walls of the locking grooves on the upper and middle spinneret plates are all embedded with magnetic blocks. The upper and middle spinneret plates are stably locked with the electromagnetic locking block through the magnetic blocks embedded in the locking grooves opened thereon, and the lower spinneret plate is stably locked with the limit block through the locking grooves opened thereon. The strong locking force provided by the electromagnetic locking block can effectively reduce the possibility of the stacked spinneret assembly detaching from the spray barrel during the spinning process.

[0015] Furthermore, the lower spinneret sheet is provided with micropores of two sizes, and the lower spinneret sheet can be rotated by the electric rotating ring to connect with the middle spinneret sheet and the upper spinneret sheet, so as to realize the switching of spinning of different sizes.

[0016] Furthermore, the micropores opened on the upper spinneret, the middle spinneret and the lower spinneret are all cylindrical, and the sizes of the cylindrical micropores on the upper spinneret, the middle spinneret and the lower spinneret decrease successively. During the spinning process, the shaping effect of the cylindrical micropores with continuously decreasing sizes on the spinning melt can effectively improve the spinning forming degree.

[0017] Furthermore, the top end of the electromagnetic locking block is fixedly connected to a limiting ring, and the limiting effect of the limiting ring enables the electromagnetic locking block to accurately lock the upper spinneret veneer and the middle spinneret veneer.

[0018] Furthermore, the collecting bin and the air supply device are connected via a connecting piece, and the collecting bin, the spray gun, the air supply device, the air supply main pipe, the driving motor, and the gear box are all connected to external fixings to ensure the working stability of the equipment.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] (1) This scheme improves the original nylon spinning process and simplifies the number of equipment used in the original process. Under the premise of ensuring accurate control of the spinning length, it can effectively reduce the overall failure rate of the device and improve the operating stability of the device. When the last fixed-length spinning is ejected from the stacked spinneret assembly, the squeezing effect of the isolation gas is cut off, so that the spinning melt residue originally contained in the micropores of the stacked spinneret assembly can be ejected together as part of the last fixed-length spinning, and a large amount of spinning melt residue will not be formed in the micropores, causing later solidification blockage, resulting in the possibility of needing to clean the micropores of the stacked spinneret assembly in advance before each start-up. This in-situ treatment method for the spinning melt residue in the micropores of the stacked spinneret assembly does not require the stacked spinneret assembly to be disassembled and cleaned, and can effectively improve the work progress.

[0022] (2) A collecting bin is arranged on the left side of the plurality of nozzles, and a plurality of slide rails are fixedly installed on the inner top of the collecting bin, and electric telescopic rods are slidably connected to the plurality of slide rails through sliders, and adhesive plates are fixedly installed on the telescopic ends of the plurality of electric telescopic rods, and elastic scrapers are bonded to the bottom ends of the adhesive plates, and a collecting box is fixedly installed on the bottom end of the collecting bin. After the air supply device is started, the air blown out by the plurality of high-pressure nozzles can not only cool the ejected spinning, but also, after the last fixed-length spinning is ejected from the stacked spinning assembly and a stage of spinning operation is completed, not only will spinning melt residue be formed in the micropores of the stacked spinning assembly, but also Spinning melt residue is formed on the inner wall of the nozzle. The spinning melt residue in the micropores has been solved by cutting off the gas. The amount of gas injected for the last time can be increased. The gas at this time does not play a role of isolation, but a cleaning role. Through the flushing effect of the gas, the spinning melt residue on the inner wall of the nozzle is blown out from the micropores of the stacked spinneret assembly together with the gas. The wind blown out by the high-pressure nozzle quickly cools the spinning melt residue and blows it onto the collecting bin. After being started by the electric telescopic rod, it drives the sliding scraping effect of the adhesive plate and the elastic scraper block on the collecting bin, and quickly scrapes the spinning melt residue into the collecting box for collection and treatment.

[0023] (3) An electrostatic suction plate is fixedly installed at a position parallel to the collecting bin and the high-pressure nozzle, and an electrostatic generator is fixedly installed at the top of the air supply device. The electrostatic generation effect of the electrostatic generator causes the air blown out from the high-pressure nozzle to carry electrostatic ions, thereby causing the residual spinning melt guided by it to carry electrostatic ions in the process of being blown to the collecting bin, and finally being adsorbed by the electrostatic suction plate installed on the collecting bin, thereby effectively reducing the possibility that the residual spinning melt will collide and splash with the collecting bin in the process of being guided by the airflow to the collecting bin, and cannot be well collected.

[0024] (4) A magnetic sheet is bonded to one end of the elastic scraper away from the electrostatic suction plate. The electrostatic suction plate can not only attract the spinning melt residue with electrostatic ions, but also attract the magnetic sheet. Through the attraction effect of the electrostatic suction plate on the magnetic sheet and the sliding effect of the electric telescopic rod in the slide rail, the lateral squeezing effect of the elastic scraper on the electrostatic suction plate is finally achieved, thereby improving the scraping effect of the elastic scraper on the spinning melt residue collected on the electrostatic suction plate and improving the cleaning efficiency.

[0025] (5) The stacked spinneret assembly includes a connecting shaft, a pair of locking rings, and upper, middle, and lower spinneret sheets stacked one above the other. The upper, middle, and lower spinneret sheets rotate on the connecting shaft. A pair of locking rings are locked to the upper and lower ends of the connecting shaft by screws. When the micropores on the stacked spinneret assembly are still clogged during long-term use, the operator removes the stacked spinneret assembly from the spinneret and then removes the pair of locking rings from the connecting shaft. The upper spinneret, the middle spinneret and the lower spinneret can be removed from the connecting shaft smoothly, and during the disassembly process, the solidified spinning melt residue will be peeled off from the upper spinneret, the middle spinneret or the lower spinneret, making it easy to clean them. By transforming the original one-piece structure of the stacked spinneret assembly into an independently detachable stacked structure, the cleaning effect of the spinning melt residue blocked in the stacked spinneret assembly can be effectively improved.

[0026] (6) The strong locking force provided by the electromagnetic locking block effectively reduces the possibility of the stacked spinneret assembly detaching from the spinneret during the spinning process.

[0027] (7) The lower spinneret sheet is provided with micro-holes of two sizes, and the lower spinneret sheet can be connected to the middle spinneret sheet and the upper spinneret sheet by rotating the lower spinneret sheet through an electric rotating ring, so as to switch between spinnings of different sizes.

[0028] (8) The micropores opened on the upper spinneret, the middle spinneret and the lower spinneret are all cylindrical, and the sizes of the cylindrical micropores on the upper spinneret, the middle spinneret and the lower spinneret decrease successively. During the spinning process, the cylindrical micropores with decreasing sizes have a shaping effect on the spinning melt, which can effectively improve the spinning forming degree.

[0029] (9) The top of the electromagnetic locking block is fixedly connected to a limiting ring. Through the limiting effect of the limiting ring, the electromagnetic locking block can accurately lock the upper spinneret veneer and the middle spinneret veneer.

[0030] (10) The collecting bin and the air supply device are connected by a connector. The collecting bin, the nozzle, the air supply device, the air supply main pipe, the driving motor, and the gear box are all connected to external fixings to ensure the working stability of the equipment.

[0047] Embodiment 1:

[0048] See also Figure 1-4A high-efficiency spinning device for nylon textile comprises a plurality of laterally evenly arranged spinning tubes 1, a plurality of spinning tubes 1 are each provided with a spiral push rod 2, the plurality of spiral push rods 2 are each driven by a driving motor 3 and a corresponding gear box, a stacked spinning assembly 7 is fixedly mounted on the bottom end of the plurality of spinning tubes 1, an air supply main pipe 5 is disposed on the right side of the plurality of spinning tubes 1, an air supply device 4 is fixedly mounted on the inlet end of the air supply main pipe 5, a plurality of air supply branch pipes 6 are fixedly connected to the outer end wall of the air supply main pipe 5, and the plurality of air supply branch pipes 6 are respectively fixedly mounted on the upper side of the outer end wall of the corresponding spinning tube 1, an air supply device 16 is disposed on the right side of the plurality of spinning tubes 1, a plurality of high-pressure nozzles 17 are fixedly mounted on the outlet end of the air supply device 16, and the air supply device 4 is intermittently opened by a control terminal.

[0049] The present invention improves the original nylon spinning process and simplifies the number of equipment used in the original process, which can effectively reduce the overall failure rate of the device and improve the operation stability of the device. In the actual operation of the device, after the spinning melt is put into the nozzle 1, it is finally ejected from the stacked spinneret assembly 7 into filaments under the thrust of the screw driven by the motor. During the spinning operation, according to the currently required spinning length, the control terminal controls the gas supply device 4 to be intermittently opened, and an appropriate amount of gas is intermittently quickly sent into multiple nozzles 1 through the gas supply main pipe 5 and the gas supply branch pipe 6. The gas forms a partition in the nozzle 1. The spinning melt content in the two gas partitions adjacent to each other is the spinning melt content actually required for the current spinning length. By utilizing the automatic partition effect of the gas, the device does not need to set a spinning metering pump in each nozzle 1 to control the spinning length, nor does it need to install a cutting device on the lower side of the stacked spinneret assembly 7 to control the spinning length. In this way, the number of equipment can be simplified while ensuring accurate control of the spinning length.

[0050] At the same time, when the last fixed-length spinning is ejected from the stacked spinneret assembly 7, the squeezing effect of the isolation gas is used to allow the spinning melt residue originally contained in the micropores of the stacked spinneret assembly 7 to be ejected together as a part of the last fixed-length spinning, and no large amount of spinning melt residue will be formed in the micropores to cause coagulation blockage in the later stage, resulting in the possibility of needing to clean the micropores of the stacked spinneret assembly 7 in advance before each start-up. Moreover, this in-situ treatment method for the spinning melt residue in the micropores of the stacked spinneret assembly 7 does not require the stacked spinneret assembly 7 to be disassembled and cleaned, and can effectively improve the progress of the operation.

[0051] See also Figure 5A collecting bin 8 is arranged on the left side of the plurality of spray barrels 1, a plurality of slide rails 10 are fixedly installed on the inner top of the collecting bin 8, an electric telescopic rod 11 is slidably connected to the plurality of slide rails 10 through a slider, an adhesive plate 12 is fixedly installed on the telescopic end of the plurality of electric telescopic rods 11, an elastic scraper block 13 is bonded to the bottom end of the adhesive plate 12, a collecting box 15 is fixedly installed on the bottom end of the collecting bin 8, and after the air supply device 16 is started, the wind blown out by the plurality of high-pressure nozzles 17 can not only cool the ejected spinning, but also, after the last fixed-length spinning is ejected from the stacked spinning assembly 7 and a stage of spinning operation is completed, not only will the spinning melt residue be formed in the micropores of the stacked spinning assembly 7, but also the spinning melt residue will be formed in the micropores of the stacked spinning assembly 7. At the same time, spinning melt residue will also be formed on the inner wall of the nozzle 1. The spinning melt residue in the micropores has been solved by isolating the gas. The amount of gas injected for the last time can be increased. The gas at this time does not play a role of isolation, but a cleaning role. Through the flushing effect of the gas, the spinning melt residue on the inner wall of the nozzle 1 is blown out from the micropores of the stacked spinneret assembly 7 together with the gas. The wind blown out by the high-pressure nozzle 17 quickly cools the spinning melt residue and blows it onto the collecting bin 8. After the electric telescopic rod 11 is started, it drives the sliding scraping effect of the adhesive plate 12 and the elastic scraper block 13 on the collecting bin 8, and quickly scrapes the spinning melt residue into the collecting box 15 for collection and treatment.

[0052] An electrostatic suction plate 9 is fixedly installed at a parallel position between the collecting bin 8 and the high-pressure nozzle 17, and an electrostatic generator 18 is fixedly installed at the top of the air supply device 16. The electrostatic generating effect of the electrostatic generator 18 makes the wind blown out by the high-pressure nozzle 17 carry electrostatic ions, so that the spinning melt guided by it will remain in the process of being blown to the collecting bin 8, and will also carry electrostatic ions, and will eventually be adsorbed by the electrostatic suction plate 9 installed in the collecting bin 8, effectively reducing the possibility of the spinning melt remaining in the process of being guided by the airflow to the collecting bin 8, colliding and sputtering with the collecting bin 8, and failing to be collected well.

[0053] A magnetic suction sheet 14 is bonded to one end of the elastic scraper block 13 away from the electrostatic suction plate 9. The electrostatic suction plate 9 can not only attract the spinning melt residue with electrostatic ions, but also attract the magnetic suction sheet 14. Through the attraction effect of the electrostatic suction plate 9 on the magnetic suction sheet 14 and the sliding effect of the electric telescopic rod 11 in the slide rail 10, the lateral extrusion effect of the elastic scraper block 13 on the electrostatic suction plate 9 is finally achieved, thereby improving the scraping effect of the elastic scraper block 13 on the spinning melt residue collected on the electrostatic suction plate 9 and improving the cleaning efficiency.

[0054] See also Figure 9-11The stacked spinneret assembly 7 includes a connecting shaft 704, a pair of locking rings 705, and upper and lower stacked spinneret single plates 701, middle and lower spinneret single plates 702, 703. The upper and lower spinneret single plates 701, 702 and 703 rotate on the connecting shaft 704. The pair of locking rings 705 are locked at the upper and lower ends of the connecting shaft 704 by screws. When the micropores on the stacked spinneret assembly 7 are still clogged during long-term use, the operator removes the stacked spinneret assembly 7 from the spray barrel 1 and then removes the pair of locking rings. 705 is removed from the connecting shaft 704, and the upper spinneret single plate 701, the middle spinneret single plate 702 and the lower spinneret single plate 703 can be smoothly removed from the connecting shaft 704, and during the removal process, the solidified spinning melt residues will be peeled off from the upper spinneret single plate 701, the middle spinneret single plate 702 or the lower spinneret single plate 703, which is convenient for cleaning. By transforming the original one-piece structure of the stacked spinneret assembly 7 into an independently detachable stacked structure, the cleaning effect of the spinning melt residues blocked in the stacked spinneret assembly 7 can be effectively improved.

[0055] See also Figure 6-8 An electric swivel 19 is installed at the bottom end of the spray barrel 1, and an electromagnetic locking block 20 is fixedly connected to the lower side of the inner end wall of the spray barrel 1. The inner end wall of the electric swivel 19 is fixedly connected to the limiting block 21. The outer end walls of the upper spinneret single plate 701, the middle spinneret single plate 702 and the lower spinneret single plate 703 are all provided with locking grooves 22. The inner end walls of the locking grooves 22 on the upper spinneret single plate 701 and the middle spinneret single plate 702 are all embedded with magnetic blocks. The upper spinneret single plate 701 and the middle spinneret single plate 702 are stably locked with the electromagnetic locking block 20 through the magnetic blocks embedded in the locking grooves 22 opened thereon, and the lower spinneret single plate 703 is stably locked with the limiting block 21 through the locking grooves 22 opened thereon. The strong locking force provided by the electromagnetic locking block 20 effectively reduces the possibility of the stacked spinneret assembly 7 being detached from the spray barrel 1 during the spinning process.

[0056] See also Figure 8 The top of the electromagnetic locking block 20 is fixedly connected to a limiting ring 23. Through the limiting effect of the limiting ring 23, the electromagnetic locking block 20 can accurately lock the upper spinneret veneer 701 and the middle spinneret veneer 702.

[0057] See also Fig. 9 The lower spinneret plate 703 is provided with micropores of two sizes, and the lower spinneret plate 703 can be rotated by the electric rotating ring 19 to connect with the middle spinneret plate 702 and the upper spinneret plate 701, so as to realize the switching of spinning of different sizes.

[0058] See also Fig.10The micropores opened on the upper spinneret veneer 701, the middle spinneret veneer 702 and the lower spinneret veneer 703 are all cylindrical, and the sizes of the cylindrical micropores on the upper spinneret veneer 701, the middle spinneret veneer 702 and the lower spinneret veneer 703 decrease successively. During the spinning process, the shaping effect of the cylindrical micropores with continuously decreasing sizes on the spinning melt can effectively improve the spinning forming degree.

[0059] See also Figure 1 The collecting bin 8 and the air supply device 16 are connected by a connecting piece, and the collecting bin 8, the spray gun 1, the air supply device 4, the air supply main pipe 5, the driving motor 3, and the gear box are all connected to the external fixing parts to ensure the working stability of the equipment.

[0060] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

The gas forms a partition in the nozzle (1). The spinning melt content in the two gas partitions adjacent to each other is the spinning melt content actually required for the current spinning length, thereby ensuring accurate control of the spinning length. At the same time, when the last fixed-length spinning is ejected from the stacked spinneret assembly (7), the squeezing effect of the partition gas allows the spinning melt residue originally contained in the micropores of the stacked spinneret assembly (7) to be ejected as part of the last fixed-length spinning, thereby increasing the amount of gas injected in the last time. At this time, the gas does not play a partition role, but a cleaning role, thereby achieving a gas flushing effect.
