Description

Technical Field

[0001] This invention relates to the field of warping equipment technology, specifically to a warping device and method for adaptive tension buffering of thin, high-drape fabric filaments. Background Technology

[0002] Lightweight, high-drape fabrics are mostly woven from untwisted or low-twisted filaments such as fine denier and ultra-fine denier polyester and nylon. These fabrics are lightweight, soft to the touch, and have excellent drape, making them widely used in high-end apparel such as dresses, shirts, and fashion garments. These filaments have fine single-filament fineness, low breaking strength, smooth fiber surface, and poor cohesion, placing stringent requirements on tension consistency, yarn friction damage control, static electricity elimination, and warp beam winding quality during the warping process. Warping, as a crucial pre-weaving step, directly determines the subsequent weaving efficiency and the quality of the finished fabric.

[0003] For example, Chinese Patent CN114395836A discloses a warping machine for antistatic yarn, including a warping machine body. Both inner walls of the warping machine body are provided with a first groove, and each first groove contains a matching slider. On the side where the two sets of sliders are close to each other, there is a second groove, and each second groove contains a matching slider. The beneficial effects are: the inclusion of an antistatic plate, antistatic rod, wires, and a ground wire achieves the effect of eliminating static electricity; the inclusion of a raised strip, spray plate, connecting hose, and water inlet hose allows for uniform spraying of water mist, increasing the yarn's humidity and effectively reducing friction, thereby indirectly reducing static electricity generation; and the inclusion of a first protrusion, a first movable strip, a sliding sleeve, a second movable strip, a second protrusion, a second through hole, and a threaded rod allows for adjustment of the spray plate angle, thereby changing the distance between the spray plate and the yarn to maintain a suitable distance, thus improving the spraying effect and further enhancing the antistatic performance. Firstly, the traditional installation position of yarn bobbins is too close to the guide frame, resulting in limited space for movement when installing or replacing yarn bobbins, making it inconvenient to move batches of yarn bobbins near the yarn frame. Secondly, the installation of yarn bobbins lacks stability; when the feeding speed increases, the yarn bobbins are prone to swaying up and down, affecting the stability of the feeding process. Finally, during the warping process, when multiple strands of yarn need to be passed through the yarn feeder, only threading hooks can be used to pass through each strand one by one, resulting in low threading efficiency. Therefore, a lightweight, high-drape fabric filament adaptive tension buffer warping device and its warping method are proposed to solve the above problems. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a lightweight, high-drape fabric filament adaptive tension buffer warping device and its warping method, which offers advantages such as easy yarn bobbin replacement and solves the problem of inconvenient yarn bobbin replacement in traditional methods.

[0005] (II) Technical Solution To achieve the above-mentioned purpose of facilitating the replacement of yarn bobbins, the present invention provides the following technical solution: a lightweight, high-drape fabric filament adaptive tension buffer warping device, comprising a yarn frame, wherein a plurality of yarn bobbins are installed on the outer surfaces of both sides of the yarn frame, and a storage groove is provided on the outer surface of the yarn bobbin, wherein a retractable and expandable clip is installed inside the storage groove, and an adjustment component is provided inside the yarn bobbin, wherein the storage and expansion of the clip is controlled by the adjustment component; The guide frame is installed on both sides of the yarn frame. The bottom end of the guide frame is equipped with a guide rail. Rollers matching the guide rail are installed at the four corners of the bottom end of the guide frame. A top frame is fixedly installed on the top of the rollers. Limiting components are provided on both sides of the top frame. The front end of the yarn rack is mounted in the chassis. There are two sets of chassis. A cable tray is fixedly installed at one end between the two sets of chassis. Several branch rods are fixedly installed inside the cable tray. A crossbar is set at the top of the cable tray. Sliders are fixedly installed at the bottom of both ends of the crossbar, and the sliders are slidably connected to both ends of the cable tray. The tension adjustment frame is located at the front end of the hub frame. There are two sets of tension adjustment frames, and a tension adjustment roller is installed between the two sets of tension adjustment frames. The take-up roller is located at the other end between the two sets of housings. A drive assembly is installed inside one of the housings, which drives the take-up roller to rotate. Mounting assemblies are provided at both ends of the take-up roller.

[0006] Furthermore, a turntable is provided at one end of the yarn bobbin, and the yarn bobbin is rotatably connected to the turntable. The adjustment assembly includes a screw rotatably installed inside the yarn bobbin. An installation ring is sleeved on the outer surface of the screw, and the installation ring is threadedly connected to the screw. A connecting block is integrally fixed on the outer surface of the installation ring. A bracket is hinged to one end of the connecting block, and one end of the bracket is hinged to the inner wall of the card holder. Rotating the adjustment knob drives the screw to rotate through the connecting rod, causing the installation ring to move along the screw. This causes the connecting block to drive the bracket to move, causing the card holder inside the storage slot to extend outward and expand, so that one end of the card holder abuts against the inner wall of the yarn bobbin, thereby fixing the yarn bobbin.

[0007] Furthermore, an adjustment knob is provided at the other end of the yarn bobbin. A limit ring is fixedly installed on the outer surface of one end of the adjustment knob. A limit groove matching the limit ring is opened on the outer surface of one end of the yarn bobbin. A connecting rod is fixedly connected to one end of the screw. An inner rod is slidably installed inside the connecting rod. A stop block is fixedly installed at one end of the inner rod. A first return spring is sleeved on the outer surface of the inner rod. The other end of the inner rod is fixedly connected to one end of the adjustment knob. Pulling the adjustment knob outward causes the inner rod inside the connecting rod to slide outward, causing the limit ring at one end of the adjustment knob to disengage from the limit groove on the surface of one end of the yarn bobbin, thus releasing the limitation on the adjustment knob.

[0008] Furthermore, several sets of guide plates are fixedly installed on the outer surfaces of both ends of the guide frame. Several guide holes are opened on the outer surface of the guide plate. An opening is provided at the top of the guide hole. Guide wheels are rotatably installed on both sides of the inner wall of the opening. The yarn is led out from the yarn bobbin and passes through the guide holes on the guide plate in sequence. The top of the guide hole is designed to be open, and guide wheels are provided on both sides of the inner wall to facilitate the threading of the yarn and then the yarn is conveyed outward.

[0009] Furthermore, the limiting component includes slide rods fixedly installed on the outer surfaces of both sides of the top frame. The inner wall of the guide rail has a groove that matches the slide rod. A locking pin is inserted inside the slide rod. The inner wall of the groove has a locking slot that matches the locking pin. A second return spring is sleeved on the outer surface of the locking pin. A retaining ring is sleeved on one end of the second return spring on the outer surface of the locking pin. An electromagnet is fixedly installed inside the top frame at the other end of the locking pin. When the electromagnet is energized, it pulls the locking pin to compress the second return spring, thereby releasing the locking pin from limiting and locking the guide frame.

[0010] Furthermore, guide rods are fixedly installed at both ends of the cable tray, and the guide rods are inserted into the interior of the slide. A fixing plate is fixedly installed on the outer surface of the guide rod, and the fixing plate is slidably connected to the inner wall of the guide rod. A third return spring is sleeved on the outer surface of the guide rod above the fixing plate. A first pin is threaded on the outer surface of the cable tray. A first insertion hole matching one end of the first pin is opened on the outer surface of the guide rod. Rotating the first pin causes one end of the first pin to disengage from the first insertion hole, releasing the restriction on the slide. The third return spring will push the slide upward, causing the slide to slide upward along the guide rod. The slide drives the top crossbar to move upward, causing the crossbar to separate from the top of the cable distribution rod. The operator can pass multiple wires through the bottom of the crossbar at the same time.

[0011] Furthermore, an adjusting cylinder is fixedly installed at the top of the tension adjusting frame, and the bottom end of the output shaft of the adjusting cylinder is fixedly connected to one end of the tension adjusting roller. Two sets of tension adjusting frames are installed below the tension adjusting roller, and a guide roller is installed between the two sets of housings at the front end of the conveying roller. After the wire is output from the coiler, it is wound around the tension adjusting roller and the conveying roller in sequence. The two ends of the tension adjusting roller are assembled on the tension adjusting frame, and the two ends of the tension adjusting roller are driven and controlled by the adjusting cylinder. The tension can be adjusted according to the real-time tension of the wire.

[0012] Furthermore, baffles are fixedly installed on the outer surfaces near both ends of the take-up roller, and each baffle has a retainer at both ends. A motor is fixedly installed inside the housing, and the output end of the motor is connected to a first pulley group and a second pulley group. The output end of the second pulley group is drivenly connected to one end of the conveyor roller. A transmission unit is fixedly installed inside the housing, and the input end of the transmission unit is drivenly connected to the output end of the first pulley group. The output end of the transmission unit is drivenly connected to a third pulley group, and the output end of the third pulley group is fixedly connected to a coupling shaft, one end of which is fixedly connected to a retainer. The motor outputs power, which drives the conveyor roller to rotate sequentially through the first pulley group and the second pulley group. At the same time, the power is transmitted to the take-up roller through the transmission unit, the third pulley group, and the coupling shaft, driving the take-up roller to rotate and perform warping and winding of the yarn. Baffles are provided at both ends of the take-up roller to limit the axial position of the yarn winding and prevent axial deviation during yarn winding.

[0013] Furthermore, the mounting assembly includes inner shafts inserted into both ends of the take-up roller. One end of the inner shaft is fixedly fitted with a locking block, which is inserted into the slot. The outer surfaces of both ends of the take-up roller are fitted with outer rings. The other end of the inner shaft passes through a groove on the outer surface of the take-up roller and is fixedly connected to the inner wall of the outer ring. The outer surface of the outer ring is threaded with a second pin. The outer surface of the take-up roller has a second insertion hole that matches the bottom end of the second pin. Rotating the second pin on the outer ring causes the second pin to disengage from the second insertion hole on the surface of the take-up roller, releasing the restriction on the outer ring. Then, the outer ring is moved along the groove, causing the locking block at one end of the inner shaft to disengage from the slot, releasing the restriction on both ends of the take-up roller.

[0014] A warping method for a self-adaptive tension buffer warping device for lightweight, high-drape fabric filaments, comprising the following steps: Step 1: Unlock the guide frame and carry out yarn spool replacement. When replacing the yarn spool, the electromagnet is energized, releasing the locking pin on the guide frame. The guide frame slides along the guide rail via the bottom rollers to achieve overall translation, creating an operating space between it and the yarn frame, making it convenient for operators to disassemble and replace the yarn spool. Step 2: Adaptive clamping and fixing of yarn bobbin. Place the yarn bobbin on the outside of the yarn tube, rotate the adjustment knob to drive the installation ring to move, and with the help of the connecting block and bracket, drive the clip in the storage slot to extend outward, so that the end of the clip is pressed against the inner wall of the yarn bobbin, which can adapt to yarn bobbins with different inner diameters and ensure rotational stability. Step 3: Reset and lock the guide tube. After the yarn bobbin is fixed, move the guide tube back to its original position, de-energize the electromagnet, and lock the guide tube. During the warping operation, the yarn bobbin rotates synchronously with the turntable to release the yarn, and the yarn is drawn through the guide tube holes of the guide plate in sequence. Step 4: The yarn collection frame is opened and closed to separate the yarns. After the yarns are guided out from the yarn rack, they enter the yarn collection frame to complete the yarn separation operation. The horizontal frame and the yarn separation rod are separated to form a threading channel. The operator passes multiple yarns through the horizontal frame from below. After the threading is completed, the yarn collection frame is closed. Step 5: Dynamically adjust the working tension of the yarn. After splitting, the yarn is wound sequentially on the tension adjusting roller and the conveying roller. During operation, the tension adjusting roller can be moved up and down along the tension adjusting frame by adjusting the cylinder according to the real-time tension of the yarn, thereby changing the gap between the roller and the conveying roller, dynamically controlling the yarn tension, avoiding yarn slack, wrinkling or breakage, and ensuring stable operation. Step Six: Power transmission. The continuous warping, winding, and roller changing motor outputs power to drive the winding roller to rotate at a constant speed, completing the warping and winding of the yarn. After the operation is completed, the fixed limit at both ends of the winding roller can be released, allowing for quick disassembly and replacement of the winding roller, thus improving the equipment's winding efficiency.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a self-adaptive tension buffer warping device and warping method for lightweight, high-drape fabric filaments, which has the following beneficial effects: 1. By installing rollers and guide rails at the bottom of the wire guide frame, when a new yarn bobbin needs to be replaced, the limit of the wire guide frame can be released first, and the rollers at the bottom can be used to pull the wire guide frame and the yarn frame apart by a certain space along the guide rail, making it convenient for workers to move the yarn bobbin for installation and replacement. 2. By setting an outwardly expandable bracket on the surface of the yarn tube, during the installation of the yarn tube, the bracket can be expanded outward from the storage slot by rotating the adjustment knob, so that one end of the bracket abuts against the inner wall of the yarn tube, ensuring the stability of the yarn tube installation. At the same time, it can install and fix yarn tubes of different specifications. 3. With the set cable tray, during the cable threading process, the limit on the slide can be released first. The slide will drive the top crossbar to move upward, so that the crossbar is separated from the top of the dividing rod. This makes it convenient to pass several wires through the bottom of the crossbar at the same time. The wires are then separated by the dividing rod. After the cable threading is completed, the crossbar is returned to the bottom and the cable tray is closed, which increases the efficiency of the cable threading. 4. The tension adjustment roller is set up so that the yarn passes through the tension adjustment roller and the conveying roller in sequence. The two ends of the tension adjustment roller are controlled by the adjustment cylinder. The tension adjustment roller can be adjusted up and down along the tension adjustment frame according to the tension of the yarn, thereby adjusting the distance between the tension adjustment roller and the conveying roller and thus controlling the tension of the yarn.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-11 The present invention provides the following technical solution: a lightweight, high-drape fabric filament adaptive tension buffer warping device, including a yarn frame 1, on which a plurality of yarn tubes 11 are installed on the outer surfaces of both sides of the yarn frame 1, and a storage groove 141 is provided on the outer surface of the yarn tube 11. A retractable and expandable card holder 14 is installed inside the storage groove 141, and an adjustment component is provided inside the yarn tube 11 to control the storage and expansion of the card holder 14. In this embodiment, the wire guide frame 2 is installed on both sides of the yarn frame 1. The bottom end of the wire guide frame 2 is equipped with a guide rail 21. Rollers 23 matching the guide rail 21 are installed at the four corners of the bottom end of the wire guide frame 2. A top frame 24 is fixedly installed on the top of the rollers 23. Limiting components are provided on both sides of the top frame 24. The limiting assembly includes slide rods 25 fixedly installed on the outer surfaces of both sides of the top frame 24. The inner wall of the guide rail 21 has a groove matching the slide rods 25. A locking pin 26 is inserted into the slide rods 25. The inner wall of the groove has a locking slot matching the locking pin 26. A second return spring 261 is sleeved on the outer surface of the locking pin 26. A retaining ring 262 is sleeved on one end of the second return spring 261 on the outer surface of the locking pin 26. An electromagnet 27 is fixedly installed inside the top frame 24 at the other end of the locking pin 26. When the electromagnet 27 is energized, it pulls the locking pin 26 to compress the second return spring 261, thereby releasing the locking pin 26 from limiting and locking the guide frame 2.

[0020] In this embodiment, a turntable 12 is provided at one end of the yarn bobbin 11, and the yarn bobbin 11 is rotatably connected to the turntable 12. The adjustment component includes a screw 15 rotatably installed inside the yarn bobbin 11. An installation ring 16 is sleeved on the outer surface of the screw 15, and the installation ring 16 is threadedly connected to the screw 15. A connecting block 161 is integrally fixedly installed on the outer surface of the installation ring 16. A bracket 142 is hinged to one end of the connecting block 161, and one end of the bracket 142 is hinged to the inner wall of the card holder 14. Rotating the adjustment knob 13 drives the screw 15 to rotate through the connecting rod 17, which drives the installation ring 16 to move along the screw 15. This causes the connecting block 161 to drive the bracket 142 to drive the card holder 14 to move, causing the card holder 14 inside the storage groove 141 to extend outward and expand, so that one end of the card holder 14 abuts against the inner wall of the yarn bobbin, thereby fixing the yarn bobbin.

[0021] The yarn bobbin 11 has an adjustment knob 13 at one end. A limit ring 131 is fixedly installed on the outer surface of one end of the adjustment knob 13. A limit groove matching the limit ring 131 is opened on the outer surface of one end of the yarn bobbin 11. A connecting rod 17 is fixedly connected to one end of the screw 15. An inner rod 171 is slidably installed inside the connecting rod 17. A stop block 172 is fixedly installed at one end of the inner rod 171. A first return spring 173 is sleeved on the outer surface of the inner rod 171. The other end of the inner rod 171 is fixedly connected to one end of the adjustment knob 13. Pulling the adjustment knob 13 outward causes the inner rod 171 inside the connecting rod 17 to slide outward, causing the limit ring 131 at one end of the adjustment knob 13 to disengage from the limit groove on the surface of one end of the yarn bobbin 11, thus releasing the limit on the adjustment knob 13.

[0022] In this embodiment, several sets of wire plates 22 are fixedly installed on the outer surfaces of both ends of the wire frame 2. Several wire holes 221 are opened on the outer surface of the wire plate 22. The top of the wire hole 221 is provided with an opening. Guide wheels 222 are rotatably installed on both sides of the inner wall of the opening. The yarn is led out from the yarn bobbin and passes through the wire holes 221 on the wire plate 22 in sequence. The top of the wire hole 221 is designed to be open, and guide wheels 222 are provided on both sides of the inner wall to facilitate the threading of the yarn and then the yarn is conveyed outward.

[0023] The working principle of this embodiment is as follows: When changing yarn bobbins, the electromagnet 27 is energized, pulling the locking post 26 to compress the second return spring 261, releasing the locking post 26 from the limit lock on the guide frame 2; the bottom of the guide frame 2 is equipped with rollers 23, which can slide along the guide rail 21 to move the guide frame 2 as a whole, opening up the operating space between it and the yarn frame 1, making it convenient for operators to move the yarn bobbins and perform yarn bobbin disassembly and replacement. During the yarn bobbin installation stage, the yarn bobbin is fitted onto the outside of the yarn bobbin 11. First, pull the adjusting knob 13 outward, causing the inner rod 171 inside the connecting rod 17 to slide outward, so that the limiting ring 131 at one end of the adjusting knob 13 disengages from the limiting groove on the surface of one end of the yarn bobbin 11, releasing the limiting effect on the adjusting knob 13. Then, rotate the adjusting knob 13, which drives the screw 15 to rotate through the connecting rod 17, causing the mounting ring 16 to move along the screw 15, thus moving the connecting block 161. The bracket 142 drives the card holder 14 to extend outward from the storage slot 141, so that one end of the card holder 14 presses against the inner wall of the yarn bobbin to fix the yarn bobbin. This accommodates yarn bobbins with different inner diameters and ensures the rotational stability of the yarn bobbin. After adjustment, the adjustment knob 13 is released, and the first return spring 173 pulls the adjustment knob 13 inward to reset it, so that the limit ring 131 is inserted into the limit groove to limit the adjustment knob 13. After the yarn bobbin is fixed, the guide frame 2 is moved and reset. Then, the electromagnet 27 is de-energized, and the second return spring 261 pushes the locking post 26 to reset. The locking post 26 is reinserted into the slot on the inner wall of the guide rail 21, locking the guide frame 2. The yarn is drawn out from the yarn bobbin and passes through the guide hole 221 on the guide plate 22 in sequence. The top of the guide hole 221 is designed to be open, and guide wheels 222 are set on both sides of the inner wall to facilitate the thread to be passed through the hole and then the yarn is conveyed outward. During the warping operation, the yarn bobbin rotates together with the turntable 12 to feed the yarn.

[0024] Please see Figure 12-18The present invention provides the following technical solution: a lightweight, high-drape fabric filament adaptive tension buffer warping device, wherein the front end of the yarn frame 1 is installed in the machine box 3, and there are two sets of machine boxes 3. A yarn collection frame 4 is fixedly installed at one end between the two sets of machine boxes 3. Several yarn distribution rods 41 are fixedly installed inside the yarn collection frame 4. A cross frame 42 is provided at the top of the yarn collection frame 4. Slide frames 43 are fixedly installed below both ends of the cross frame 42, and the slide frames 43 are slidably connected to both ends of the yarn collection frame 4. In this embodiment, guide rods 45 are fixedly installed at both ends of the inside of the cable tray 4, and the guide rods 45 are inserted into the inside of the slide 43. A fixing plate 46 is fixedly installed on the outer surface of the guide rod 45, and the fixing plate 46 is slidably connected to the inner wall of the guide rod 45. A third return spring 47 is sleeved on the outer surface of the guide rod 45 above the fixing plate 46. A first pin 44 is threaded on the outer surface of the cable tray 4. A first insertion hole 48 matching one end of the first pin 44 is opened on the outer surface of the guide rod 45. Rotating the first pin 44 causes one end of the first pin 44 to disengage from the first insertion hole 48, releasing the restriction on the slide 43. The third return spring 47 will push the slide 43 upward, causing the slide 43 to slide upward along the guide rod 45. The slide 43 drives the top crossbar 42 to move upward, causing the crossbar 42 to separate from the top of the cable divider 41. The operator can pass multiple wires through the bottom of the crossbar 42 at the same time.

[0025] In this embodiment, the tension adjusting frame 5 is set at the front end of the hub frame 4, and there are two sets of tension adjusting frames 5. A tension adjusting roller 52 is installed between the two sets of tension adjusting frames 5. The tension adjusting frame 5 is fixedly equipped with an adjusting cylinder 51 at its top, and the bottom end of the output shaft of the adjusting cylinder 51 is fixedly connected to one end of the tension adjusting roller 52. Two sets of tension adjusting frames 5 are installed below the tension adjusting roller 52, and a conveying roller 53 is installed between the two sets of machine housings 3 at the front end of the conveying roller 53. After the wire is output from the wire collector 4, it is wound around the tension adjusting roller 52 and the conveying roller 53 in sequence. The tension adjusting roller 52 is assembled at both ends of the tension adjusting frame 5, and the tension adjusting roller 52 is driven and controlled by the adjusting cylinder 51 at both ends. The tension can be adjusted according to the real-time tension of the wire.

[0026] In this embodiment, the take-up roller 6 is located at the other end between the two sets of housings 3. A drive assembly is installed inside one of the housings 3, which drives the take-up roller 6 to rotate. Mounting assemblies are provided at both ends of the take-up roller 6.

[0027] Among them, the take-up roller 6 has baffles 61 fixedly installed on its outer surface near both ends, and each baffle 61 has a retainer 62 at both ends. A motor 32 is fixedly installed inside the housing 3. The output end of the motor 32 is connected to a first pulley group 33 and a second pulley group 34. The output end of the second pulley group 34 is drivenly connected to one end of the conveyor roller 53. A transmission unit 35 is fixedly installed inside the housing 3, and the input end of the transmission unit 35 is drivenly connected to the output end of the first pulley group 33. The output end of the transmission unit 35... A third pulley group 36 is connected to the transmission. The output end of the third pulley group 36 is fixedly connected to a coupling 37, and one end of the coupling 37 is fixedly connected to the card holder 62. The motor 32 outputs power, which drives the conveyor roller 53 to rotate sequentially through the first pulley group 33 and the second pulley group 34. At the same time, the power is transmitted to the take-up roller 6 through the transmission unit 35, the third pulley group 36, and the coupling 37, driving the take-up roller 6 to rotate and warp and wind the yarn. The take-up roller 6 is equipped with baffles 61 at both ends to limit the axial position of the yarn winding and prevent axial deviation during the winding of the yarn.

[0028] This embodiment also requires further explanation that the mounting assembly includes an inner shaft 63 inserted at both ends of the take-up roller 6. One end of the inner shaft 63 is fixedly mounted with a locking block 64, and the locking block 64 is inserted into the slot 62. The outer surfaces of both ends of the take-up roller 6 are fitted with outer rings 65. The other end of the inner shaft 63 passes through a groove opened on the outer surface of the take-up roller 6 and is fixedly connected to the inner wall of the outer ring 65. The outer surface of the outer ring 65 is threaded with a second pin 66. The outer surface of the take-up roller 6 has a second insertion hole 67 that matches the bottom end of the second pin 66. Rotating the second pin 66 on the outer ring 65 causes the second pin 66 to disengage from the second insertion hole 67 on the surface of the take-up roller 6, releasing the restriction on the outer ring 65. Then, the outer ring 65 is moved along the groove, causing the locking block 64 at one end of the inner shaft 63 to disengage from the slot 62, releasing the restriction on both ends of the take-up roller 6.

[0029] The working principle of this embodiment is as follows: After the yarn is drawn out from the yarn rack 1, it first enters the yarn collection rack 4 for yarn separation and threading. During the threading operation, the first pin 44 is rotated to disengage one end of the first pin 44 from the first insertion hole 48, releasing the limit on the slide 43. The third return spring 47 will push the slide 43 upward, causing the slide 43 to slide upward along the guide rod 45. The slide 43 drives the top crossbar 42 to move upward, separating the crossbar 42 from the top of the yarn separating rod 41. The operator can pass multiple yarns through the crossbar 42 at the same time, relying on the yarn separating rod 41 to complete the yarn separation. After the threading is completed, the slide 43 drives the crossbar 42 to return downward, squeezing the third return spring 47. The crossbar 42 and the top of the yarn separating rod 41 close, completing the closure of the yarn collection rack 4 and improving the yarn threading efficiency.

[0030] After the yarn is output from the coiler 4, it is wound sequentially around the tension regulating roller 52 and the conveying roller 53. The tension regulating roller 52 is mounted on the tension regulating frame 5 at both ends, and the tension regulating roller 52 is driven and controlled by the regulating cylinder 51 at both ends. According to the real-time tension of the yarn, the tension regulating roller 52 can be moved up and down along the tension regulating frame 5 by the regulating cylinder 51, thereby changing the roller gap between the tension regulating roller 52 and the conveying roller 53, and thus adjusting the yarn tension in real time.

[0031] After tension adjustment, the yarn is guided by guide roller 31 and then conveyed to take-up roller 6. Motor 32 outputs power, which drives conveyor roller 53 to rotate through first pulley group 33 and second pulley group 34 in sequence. At the same time, it is transmitted to take-up roller 6 through transmission group 35, third pulley group 36 and connecting shaft 37, driving take-up roller 6 to rotate and warp and wind yarn. The take-up roller 6 is equipped with baffles 61 at both ends to limit the axial position of the yarn winding and prevent axial deviation during yarn winding. When the take-up roller 6 is disassembled and replaced after winding, first rotate the second pin 66 on the outer ring 65 to disengage the second pin 66 from the second insertion hole 67 on the surface of the take-up roller 6, releasing the restriction on the outer ring 65. Then move the outer ring 65 along the slide groove to drive the locking block 64 at one end of the inner shaft 63 to disengage from the locking seat 62, releasing the restriction on both ends of the take-up roller 6, making it convenient to replace the take-up roller 6.

10. A warping method for a lightweight, high-drape fabric filament adaptive tension buffer warping device according to any one of claims 1-9, characterized in that, The steps are as follows: Step 1: Unlock the wire frame and carry out yarn spool replacement. When replacing the yarn spool, the electromagnet (27) is energized, releasing the locking pin (26) on the wire frame (2). The wire frame (2) slides along the guide rail (21) via the bottom roller (23) to achieve overall translation, forming an operating space between it and the yarn frame (1), which is convenient for operators to disassemble and replace the yarn spool. Step 2: Adaptive clamping and fixing of yarn bobbin. Place the yarn bobbin on the outside of the yarn bobbin (11), rotate the adjustment knob (13) to drive the installation ring (16) to move, and cooperate with the connecting block (161) and the bracket (142) to drive the card holder (141) in the storage groove (141) to extend outward, so that the end of the card holder (14) abuts against the inner wall of the yarn bobbin, adapting to yarn bobbins with different inner diameters and ensuring rotational stability; Step 3: Reset and lock the wire guide. After the wire guide yarn bobbin is fixed, move the wire guide (2) back to its original position, de-energize the electromagnet (27), and lock the wire guide (2). During the warping operation, the yarn bobbin rotates synchronously with the turntable (12) to release the wire, and the yarn leads out passes through the wire hole (221) of the wire guide plate (22) in sequence. Step 4: Open and close the yarn collection frame to separate the yarns and arrange the yarns. After the yarns are led out from the yarn rack (1), they enter the yarn collection frame (4) to complete the yarn separation operation. Separate the horizontal frame (42) from the yarn separation rod (41) to form a threading channel. The operator passes multiple yarns through the horizontal frame (42). After the threading is completed, close the yarn collection frame (4). Step 5: Dynamically adjust the working tension of the yarn. After the yarn is split, it is wound around the tension adjusting roller (52) and the conveying roller (53) in sequence. During the operation, the tension adjusting roller (52) can be moved up and down along the tension adjusting frame (5) by adjusting the cylinder (51) according to the real-time tension of the yarn, so as to change the gap between the roller and the conveying roller (53), dynamically adjust the tension of the yarn, avoid the yarn from loosening, wrinkling or breaking, and ensure stable operation. Step 6: Power transmission, continuous warping and winding and roller changing motor (32) outputs power to drive the winding roller (6) to rotate at a constant speed to complete the warping and winding of the yarn. After the operation is completed, the fixed limit at both ends of the winding roller (6) can be released, and the winding roller (6) can be quickly disassembled and replaced to improve the equipment's winding efficiency.
