Description

Technical Field

[0001] This utility model relates to the technical field of yarn production, and in particular to a winding device for packaged yarn. Background Technology

[0002] The basic process of yarn production is roughly as follows: spinning (chip drying, spinning, texturing, initial twisting, re-twisting, winding), and possible post-processing (dyeing, inspection, packaging). In the post-processing stage, such as when the yarn in cones / bodies enters the subsequent dyeing process, in order to ensure that the dye penetrates the yarn evenly for dyeing, the cones / bodies need to be rewound into skeins. The loose structure of the skeins improves the dyeing quality of the yarn.

[0003] For example, Chinese patent document CN205241932U discloses a stranding machine, which includes a frame with stranding frame rods arranged on the frame. The stranding frame rods include a main shaft, frame rods arranged parallel to the main shaft, and two sets of connecting assemblies for connecting the frame rods to the main shaft. Each connecting assembly includes a sliding rod connected to the frame rod, a fixed disk for sliding the sliding rod, and a rotating disk for radially moving the sliding rod on the fixed disk. The rotating disk is threadedly connected to the sliding rod. Thus, stranding is achieved by rewinding the yarn bobbins / tubes onto the frame rods.

[0004] However, existing yarn winding machines have the following shortcomings in practical use: after the yarn is wound into a strand, the skein needs to be slid off the frame bars along the axial direction of the frame bars. This easily leads to problems such as yarn collapse and tangling. Therefore, to avoid this problem, the thickness of the skein is not very large (the common thickness range of 30mm to 50mm in the industry). When it exceeds the above value, yarn collapse and tangling will inevitably occur after the skein is slid off the frame bars. Therefore, in order to solve the above-mentioned defects of the yarn winding machine, the skein winding device of this application is proposed. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a winding device for winding yarn that can effectively increase the thickness of the yarn and effectively avoid yarn collapse and tangling.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A winding device for packaged yarn includes a machine base and a yarn feeding mechanism disposed on the machine base. The yarn feeding mechanism is used to release yarn bobbins / tubes. The device also includes:

[0008] A stranding mechanism, comprising a spinning tube and at least one stranding frame, the spinning tube being rotatably mounted on the machine base, and the stranding frame being detachably coaxially mounted with the spinning tube; and

[0009] A winding mechanism includes an adjusting drive, a crossbeam, a traverse drive, and at least one lead block. The crossbeam is slidably mounted on the machine base and is located between the pay-off mechanism and the stranding frame. The adjusting drive is mounted on the machine base, and its output shaft is connected to the crossbeam. The adjusting drive is used to move the crossbeam closer to or further away from the stranding frame. The traverse drive is mounted on the crossbeam, and the lead block is mounted on the output shaft of the traverse drive. The traverse drive is used to drive the lead block to reciprocate along the axial direction of the stranding frame.

[0010] Optionally, the pitch-adjusting drive includes a pitch-adjusting motor and a screw. The pitch-adjusting motor is mounted on the machine base, the screw is screwed to the crossbeam, and one end of the screw is connected to the output shaft of the pitch-adjusting motor.

[0011] Optionally, the lateral movement drive includes a lateral movement motor, a lateral movement belt, a sliding shaft, and two pulleys. The two pulleys are rotatably mounted on the crossbeam, the lateral movement belt is sleeved on the two pulleys, the lateral movement motor is mounted on the crossbeam, and the output shaft of the lateral movement motor is connected to one of the pulleys. The sliding shaft is slidably mounted on the crossbeam along the axial direction of the stranding frame, and the sliding shaft is connected to the lateral movement belt. Each of the guide blocks is spaced apart on the sliding shaft.

[0012] Optionally, a plurality of guide sleeves are spaced apart on the cross frame, and the sliding shaft is slidably connected to each of the guide sleeves.

[0013] Optionally, the yarn forming frame includes a sleeve and a plurality of support bars, each of the support bars being arranged at equal angles around the circumference on the outer side wall of the sleeve, and both ends of each support bar being connected to both ends of the sleeve, and the yarn being wound around each of the support bars to form a rolled yarn.

[0014] Optionally, at least one protrusion is provided on the outer side wall of the spiral tube along the axial direction, and at least one slot is provided on the inner side wall of the sleeve along the axial direction. When the sleeve is fitted onto the spiral tube, each of the protrusions is received in the slot in a corresponding manner.

[0015] Optionally, the stranding mechanism further includes a rotary motor, which is mounted on the machine base. The output shaft of the rotary motor is connected to the spiral tube, and the rotary motor is used to drive the spiral tube to rotate.

[0016] Optionally, the stranding mechanism further includes a plug, which is disposed at the end of the spiral tube away from the rotary motor, and the plug is used to limit the movement of each stranding frame.

[0017] Compared with the prior art, the present invention has at least the following advantages:

[0018] Throughout the winding process of the rolled yarn, the adjusting drive unit drives the cross frame to slide away from the stranding frame by a certain distance, so that the distance between the conductor block and the stranding frame remains approximately constant. That is, throughout the winding process of the rolled yarn, the distance between the conductor block and the surface of the rolled yarn on the stranding frame remains approximately constant, so that the winding force of the yarn on the stranding frame remains approximately constant. Furthermore, after the rolled yarn is wound on the stranding frame, by removing the stranding frame together with the rolled yarn from the spinning tube, any friction between the rolled yarn and the equipment parts can be avoided when it is removed. Therefore, rolled yarn of any thickness can be wound without the problem of yarn collapse or tangling. Attached Figure Description

[0032] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0033] like Figures 1 to 4As shown, a yarn winding device 10 includes a machine base 100, a yarn feeding mechanism 200, a yarn forming mechanism 300, and a winding mechanism 400. The yarn feeding mechanism 200 is mounted on the machine base 100 and is used to release yarn from bobbins / tubes. The yarn forming mechanism 300 includes a spinning tube 310 and at least one yarn forming frame 320. The spinning tube 310 is rotatably mounted on the machine base 100, and the yarn forming frame 320 is detachably coaxially mounted with the spinning tube 310. The winding mechanism 400 includes a pitch adjustment drive 410, a crossbeam 420, a lateral movement drive 430, and at least one conductor block 44. 0. The crossbeam 420 is slidably mounted on the machine base 100 and is located between the wire feeding mechanism 200 and the stranding frame 320. The pitch adjustment drive 410 is mounted on the machine base 100 and its output shaft is connected to the crossbeam 420. The pitch adjustment drive 410 is used to drive the crossbeam 420 to move closer to or further away from the stranding frame 320. The transverse movement drive 430 is mounted on the crossbeam 420 and the conductor block 440 is mounted on the output shaft of the transverse movement drive 430. The transverse movement drive 430 is used to drive the conductor block 440 to reciprocate along the axial direction of the stranding frame 320.

[0034] It should be noted that the winding device 10 of this application has a vertical wiring structure. Specifically, the pay-off mechanism 200 and the winding mechanism 400 are located on one side of the stranding mechanism 300, and the pay-off mechanism 200 and the winding mechanism 400 are arranged from bottom to top. The pay-off mechanism 200 is used to release the bobbin or tube yarn, so that the yarn of the bobbin / tube yarn is rewound onto the stranding mechanism 300 by the winding mechanism 400, and finally formed into a skein on the stranding mechanism 300. Further, the stranding mechanism 300 includes a spiral tube 310 and a stranding frame 320 fitted on the spiral tube 310. Thus, the stranding frame 320 can slide along the axial direction of the spiral tube 310 to fit onto the spiral tube 310, or be removed from the spiral tube 310. When the spiral tube 310 rotates, it can drive the multiple stranding frames 320 fitted on the spiral tube 310 to rotate simultaneously. Furthermore, the pitch adjustment drive 410 can drive the crossbeam 420 to slide on the machine base 100, thereby allowing the crossbeam 420 to slide closer to or further away from the stranding frame 320. Furthermore, the lateral movement drive 430 can drive the conductor block 440 to slide laterally on the crossbeam 420. Thus, when the pay-off mechanism 200 releases the bobbin / tube yarn, the yarn is guided by the guide block 440. As the guide block 440 slides laterally along the axis of the winding frame 320 on the crossbeam 420, and simultaneously the spinning tube 310 drives the winding frame 320 to rotate continuously, the yarn is evenly wound onto the winding frame 320. After a certain length of yarn is released from the bobbin / tube yarn, or after a certain period of time, the thickness of the wound yarn on the winding frame 320 increases. Therefore, the adjustment drive 410 drives the crossbeam 420 to slide relative to the machine base 100, causing the guide block 440 to move away from the winding frame 320 by a certain distance. Thus, throughout the entire winding process of the wound yarn, the adjustment drive 410 drives the crossbeam 420 to slide away from the winding frame 320 by a certain distance, thereby ensuring the guide block 440 remains evenly wound. The distance between the wire block 440 and the stranding frame 320 remains approximately constant. That is, during the entire winding process of the coiled yarn, the distance between the wire block 440 and the surface of the coiled yarn on the stranding frame 320 remains approximately constant. This ensures that the winding force of the yarn on the stranding frame 320 remains approximately constant, thus preventing the formation of coiled yarn of any thickness without the problem of yarn collapse or tangling. Furthermore, after the coiled yarn is wound on the stranding frame 320, it can be removed from the spinning tube 310 along with the stranding frame 320. This avoids any friction between the coiled yarn and the equipment parts during removal. Therefore, even if the thickness of the coiled yarn exceeds the current common specifications (currently, the common specifications are 30mm to 50mm), for example, a thickness of 100mm to 300mm, the problem of yarn collapse or tangling can be avoided.In existing technologies, as the thickness of the skein increases, the distance between the unwinding head and the surface of the skein gradually decreases because the unwinding head remains stationary. This means that the winding force of the yarn around the skein increases, resulting in a loose inner layer and a dense outer layer structure in the skein. This structure of the skein makes it prone to problems such as yarn collapse and yarn tangling. In particular, in existing technologies, when the skein is taken out of the skeining machine after it has been skeined, the friction between the skein and the parts of the skeining machine further increases the risk of yarn collapse and yarn tangling.

[0035] Furthermore, it should be noted that the winding device 10 of this application can wind yarn of any thickness. When the thickness of the yarn increases, it means that the volume of a single yarn increases, which also means that the yarn length of a single yarn increases. Therefore, when using the winding device 10 of this application and the existing skeining machine to skein yarn of the same length, the yarn wound by the winding device 10 of this application is thicker, which means that the wound yarn is longer, and the total number of yarns is less. Since the completed yarn needs to be removed after a single yarn is skeined before skeining can continue, the total number of yarns is less, which means that the winding time of a single yarn can be extended, the number of times the yarn is unloaded can be reduced, and the effective skeining production efficiency of yarn can be improved.

[0036] like Figure 4 As shown, in one embodiment, the pitch adjustment drive 410 includes a pitch adjustment motor 411 and a screw 412. The pitch adjustment motor 411 is mounted on the machine base 100, and the screw 412 is screwed to the cross frame 420. One end of the screw 412 is connected to the output shaft of the pitch adjustment motor 411.

[0037] It should be noted that the machine base 100 is equipped with several slide rails, and the crossbeam 420 is mounted on each slide rail, allowing the crossbeam 420 to reciprocate relative to the machine base 100. The screw 412 is screwed to the crossbeam 420. Thus, when the pitch motor 411 drives the screw 412 to rotate, it causes the crossbeam 420 to reciprocate along the front-back direction on the machine base 100. This allows the wire block 440 mounted on the crossbeam 420 to reciprocate relative to the machine base 100, enabling the wire block 440 to move closer to or further away from the stranding frame 320. In one embodiment, the output shaft of the pitch motor 411 can be directly fixed to the screw 412, or it can be connected via a belt.

[0038] like Figure 4As shown, in one embodiment, the transverse drive 430 includes a transverse motor 431, a transverse belt 432, a sliding shaft 433, and two pulleys 434. The two pulleys 434 are rotatably mounted on the cross frame 420. The transverse belt 432 is sleeved on the two pulleys 434. The transverse motor 431 is mounted on the cross frame 420, and the output shaft of the transverse motor 431 is connected to one of the pulleys 434. The sliding shaft 433 is slidably mounted on the cross frame 420 along the axial direction of the stranding frame 320, and the sliding shaft 433 is connected to the transverse belt 432. Each conductor block 440 is spaced apart on the sliding shaft 433.

[0039] It should be noted that when multiple conductor blocks 440 are configured, and each conductor block 440 corresponds to a stranding frame 320, the transverse drive component 430 is configured as described above in order to enable each conductor block 440 to reciprocate synchronously on the cross frame 420. Specifically, two pulleys 434 are mounted on the cross frame 420 via bearings, a transverse belt 432 is fitted onto the two pulleys 434, and a sliding shaft 433 is slidably mounted on the cross frame 420. The axis of the sliding shaft 433 is parallel to the axis of the spiral tube 310, and the sliding shaft 433 is fixedly connected to the transverse belt 432. Each conductor block 440 is spaced apart and mounted on the sliding shaft 433. Thus, the transverse motor 431 drives the transverse belt 432 to reciprocate, causing the transverse belt 432 to drive the sliding shaft 433 to reciprocate on the transverse frame 420. This causes each conductor block 440 to reciprocate relative to the transverse frame 420. Each conductor block 440 corresponds to a stranding frame 320 and reciprocates. As the spin tube 310 drives each stranding frame 320 to rotate simultaneously, multiple conductor blocks 440 can wind the yarn onto multiple stranding frames 320 to form multiple rolls of yarn. This effectively improves the yarn stranding production efficiency.

[0040] like Figure 1 and Figure 4 As shown, in one embodiment, a plurality of guide sleeves 450 are spaced apart on the cross frame 420, and the sliding shaft 433 is slidably connected to each guide sleeve 450.

[0041] It should be noted that, in order to improve the sliding stability of the slide shaft 433, multiple guide sleeves 450 are installed at intervals on the cross frame 420, and the slide shaft 433 is adapted to pass through each guide sleeve 450, so that the slide shaft 433 can slide axially along the guide sleeve 450.

[0042] like Figure 3 As shown, in one embodiment, the yarn forming frame 320 includes a sleeve 321 and a plurality of support bars 322. Each support bar 322 is arranged at equal angles around the outer side wall of the sleeve 321, and both ends of each support bar 322 are respectively connected to both ends of the sleeve 321. The yarn is used to be wound around each support bar 322 to form a rolled yarn.

[0043] It should be noted that the sleeve 321 has a through hole in its shaft, and each support bar 322 has a U-shaped structure. Both ends of each support bar 322 are welded and fixed to both ends of the sleeve 321. Thus, when the yarn is wound around each support bar 322, a rolled yarn can be formed. After the rolled yarn is wound, the winding frame 320, along with the rolled yarn supported by each support bar 322, is removed from the spinning tube 310. The rolled yarn can be wrapped and packaged with cloth strips before being removed from each support bar 322, thus avoiding problems such as yarn collapse and tangling. Further, in one embodiment, six support bars 322 are provided, and the six support bars 322 are distributed at equal angles to each other on the outer peripheral wall of the sleeve 321.

[0044] like Figure 3 As shown, in one embodiment, at least one protrusion 330 is provided on the outer side wall of the spiral tube 310 along the axial direction, and at least one slot 3211 is provided on the inner side wall of the sleeve 321 along the axial direction. When the sleeve 321 is fitted onto the spiral tube 310, each protrusion 330 is accommodated in each slot 3211 in a corresponding manner.

[0045] It should be noted that the above-mentioned structural scheme is designed to allow the stranding frame 320 to slide along the axial direction of the spinning tube 310, while ensuring that the spinning tube 310 can stably drive the stranding frame 320 to rotate. Specifically, a protrusion 330 is provided on the outer wall of the spinning tube 310, and a groove 3211 is provided on the inner wall of the sleeve 321, wherein the protrusion 330 and the groove 3211 are adapted to each other. Thus, when the protrusion 330 and the groove 3211 are aligned, the sleeve 321 can slide along the axial direction of the spinning tube 310. When the spinning tube 310 rotates, each stranding frame 320 rotates with the spinning tube 310, so that the yarn can be wound on the stranding frame 320 to form a packaged strand. After winding is completed, the stranding frame 320 can be quickly removed from the spinning tube 310, or the stranding frame 320 can be quickly loaded onto the spinning tube 310.

[0046] like Figure 2 As shown, in one embodiment, the stranding mechanism 300 further includes a rotary motor 340, which is mounted on the machine base 100. The output shaft of the rotary motor 340 is connected to the spinning tube 310, and the rotary motor 340 is used to drive the spinning tube 310 to rotate.

[0047] It should be noted that, in order for the spinning tube 310 to continuously drive the winch 320 to rotate, a rotary motor 340 is installed on the machine base 100 to drive the spinning tube 310 to rotate continuously. It should be noted that the output shaft of the rotary motor 340 can be directly coaxially mounted with the spinning tube 310, allowing the rotary motor 340 to directly drive the spinning tube 310 to rotate. Alternatively, it can drive the spinning tube 310 to rotate through intermediate components such as a reducer. Furthermore, it can also drive the spinning tube 310 to rotate through intermediate components such as a belt assembly. The specific connection structure is not limited; it is only necessary to ensure that the rotary motor 340 can drive the spinning tube 310 to rotate. This application illustrates a specific embodiment in which a rotary motor 340 drives the middle position of the spinning tube 310 via a belt to rotate the spinning tube 310. Thus, multiple stranding frames 320 can be mounted at both ends of the spinning tube 310 where it is connected to the rotary motor 340, thereby maintaining the balance of the spinning tube 310 and ensuring that the yarn is stably wound onto each stranding frame 320. In one embodiment, the spinning tube 310 is rotatably mounted on the machine base 100 via bearings. Thus, the rotary motor 340 drives the spinning tube 310 to rotate stably, thereby ensuring the stable rotation of each stranding frame 320 on the spinning tube 310.

[0048] like Figure 3 As shown, in one embodiment, the stranding mechanism 300 further includes a plug 350, which is disposed at the end of the spiral tube 310 away from the rotating motor 340, and is used to limit the movement of each stranding frame 320.

[0049] It should be noted that since the multiple stranding frames 320 are fitted and fixed to the spiral tube 310 from one end, a plug 350 is installed at the end of the spiral tube 310 to prevent the stranding frames 320 from detaching. Thus, the plugs 350 limit and fix each stranding frame 320, preventing it from sliding off the spiral tube 310. In one embodiment, two plugs 350 are provided, one at each end of the spiral tube 310.

[0050] like Figure 1 and Figure 5As shown, in one embodiment, the yarn feeding mechanism 200 includes a yarn feeding shaft 210, a yarn feeding motor 220, a plurality of yarn feeding posts 230, a plurality of yarn feeding rollers 240, and a plurality of yarn pressing structures 250. Each yarn feeding post 230 is spaced apart on the machine base 100 and is used to fix the yarn bobbin. The yarn feeding shaft 210 is rotatably mounted on the machine base 100 and is located between the yarn feeding posts 230 and the stranding frame 320. The yarn feeding motor 220 is mounted on the machine base 100 and its output shaft is connected to the yarn feeding shaft 210. Each yarn feeding roller 240 is spaced apart on the yarn feeding shaft 210. Each yarn pressing structure 250 is rotatably mounted on the machine base 100 and is used to abut against each yarn feeding roller 240. The yarn pressing structure 250 is used to press and clamp the yarn together with the yarn feeding roller 240.

[0051] It should be noted that the yarn bobbin is the raw material for the yarn, and it is placed on the pay-off post 230. After being released from the yarn bobbin, the yarn passes between the pay-off reel 240 and the pressing structure 250, and finally winds onto the stranding frame 320. Thus, as the pay-off motor 220 drives the pay-off shaft 210 to rotate, each pay-off reel 240 rotates accordingly, and each pressing structure 250 abuts against each pay-off reel 240. Therefore, as the pay-off reels 240 rotate, the yarn is continuously drawn from the yarn bobbin and eventually stably wound onto the stranding frame 320.

[0052] like Figure 5 and Figure 6 As shown, in one embodiment, the pressing structure 250 includes a swing arm 251, a spring 252, a pressing belt 253, and two rotating wheels 254. One end of the swing arm 251 is rotatably mounted on the machine base 100, and the two rotating wheels 254 are rotatably mounted on the swing arm 251 at intervals. The pressing belt 253 is sleeved on the two rotating wheels 254. The spring 252 is connected to the machine base 100 and the swing arm 251 respectively. The spring 252 is used to drive the swing arm 251 to rotate so that the pressing belt 253 abuts against the outer wall of the pay-off wheel 240, so that the pressing belt 253 and the pay-off wheel 240 jointly press and clamp the yarn.

[0053] It should be noted that the elastic tension of the spring 252 causes the pressing belt 253 to press against the outer wall of the pay-off wheel 240. The yarn is pressed and clamped by the pressing belt 253 and the pay-off wheel 240. Thus, when the pay-off shaft 210 drives the pay-off wheel 240 to rotate, the pressing belt 253 passively follows the rotation, thereby allowing the yarn to be stably released from the yarn bobbin.

[0054] like Figure 5 and Figure 6As shown, in one embodiment, the wire feeding mechanism 200 further includes a guide shaft 260, a guide drive member 270, and several guide blocks 280. The guide shaft 260 is slidably disposed on the machine base 100 along the axial direction of the spiral tube 310. The guide drive member 270 is disposed on the machine base and connected to the guide shaft 260. The guide drive member 270 is used to drive the guide shaft 260 to reciprocate along the axial direction. Each guide block 280 is also disposed at intervals on the guide shaft 260, and each guide block 280 is located between each wire feeding post 230 and each wire feeding wheel 240.

[0055] It should be noted that, in order to ensure that the yarn is accurately clamped by the pressure belt 253 and the feed roller 240 when released from the yarn bobbin, a guide shaft 260 is provided to drive the guide block 280 to reciprocate axially, ensuring that the yarn is always guided by the guide block 280 between the feed roller 240 and the pressure belt 253. Furthermore, in one embodiment, the guide shaft 260 is slidably mounted on the machine base 100 via bearings.

[0056] Furthermore, such as Figure 5 As shown, in one embodiment, the guide drive 270 includes a guide motor 271, an eccentric wheel 272, a rocker arm 273, and a slide plate 274. The slide plate 274 is mounted on the guide shaft 260, the guide motor 271 is mounted on the machine base 100, the eccentric wheel 272 is mounted on the output shaft of the guide motor 271, and the two ends of the rocker arm 273 are rotatably connected to the eccentric wheel 272 and the slide plate 274, respectively.

[0057] Thus, the guide motor 271 drives the eccentric wheel 272 to rotate continuously, causing the swing arm 273 to drive the slide plate 274 to slide on the machine base 100, thereby enabling the guide shaft 260 to drive each guide block 280 to slide back and forth relative to the machine base 100.

[0058] like Figure 1 , Figure 5 and Figure 6 As shown, in one embodiment, the wire feeding mechanism 200 further includes a plurality of guide blocks 290, each guide block 290 being spaced apart on the machine base 100, and each guide block 290 being located between each wire feeding wheel 240 and each wire block 440.

[0059] Thus, under the combined action of guide block 290 and guide block 280, the yarn is always clamped by the pay-off wheel 240 and the pressure belt 253, thereby allowing the yarn to be released stably from the yarn bobbin.

[0060] like Figure 7 , Figure 8 As shown, a method for dyeing skein yarn, used to dye skein yarn formed by the aforementioned skein yarn winding device 10, includes the following steps:

[0061] Step S1: Obtain the rolled yarn and wrapping cloth, and wrap the wrapping cloth around the outside of the rolled yarn to obtain the yarn roll to be dyed;

[0062] Step S2: Obtain the dyeing cage 30 and place several rolls of yarn to be dyed coaxially inside the dyeing cage 30.

[0063] Step S3: Inject dye into dyeing cage 30 and dye the yarn roll to be dyed.

[0064] It should be noted that after wrapping the cloth around the outer wall of the rolled yarn to form a yarn roll to be dyed, multiple yarn rolls to be dyed are placed in the dyeing cage 30, with each yarn roll arranged coaxially. By injecting dye into the dyeing cage, the dye ultimately dyes the yarn rolls to be dyed.

[0065] like Figure 8 As shown, in one embodiment, in step S2, the dyeing cage 30 includes an outer cage 31 and an inner cage 32. The inner cage 32 is coaxially disposed inside the outer cage 31, and each yarn roll to be dyed is sleeved on the inner cage 32 so that each yarn roll to be dyed is placed coaxially inside the dyeing cage 30.

[0066] It should be noted that after the yarn rolls to be dyed are sequentially placed inside the inner cage 32, each yarn roll can be placed coaxially within the dyeing cage 30. When dye is injected into the inner cage 32, the dye can fully and evenly contact the yarn rolls as it flows from the inner cage 32 to the outer cage 31. This effectively improves the dyeing quality of the rolled yarn. It is particularly important to note that the rolled yarn wound by the rolled yarn winding device 10 of this application is thick. Therefore, when dyeing using the aforementioned dyeing cage 30, the dyeing efficiency and effect can be effectively improved by repeatedly circulating the dye from the inner cage 32 to the outer cage 31.

[0067] like Figure 9 and Figure 10 As shown, in one embodiment, before step S1, the following steps are included: obtaining the material picking mechanism 40, placing the stranding frame 320 together with the rolled strand on the material picking mechanism 40, and taking the rolled strand from the stranding frame 320 through the material picking mechanism 40. The material picking mechanism 40 includes a central shaft 41, a slide rod 42, a plurality of first arms 43, a plurality of second arms 44, and a plurality of support rods 45. The slide rod 42 is slidably disposed coaxially at one end of the central shaft 41. One end of each first arm 43 is rotatably connected to the central shaft 41, and the other end of each first arm 43 is rotatably connected to each support rod 45. One end of each second arm 44 is rotatably connected to the slide rod 42, and the other end of each second arm 44 is slidably connected to each support rod 45. Each first arm 43 is rotatably connected to each second arm 44.

[0068] It should be noted that after removing the stranding frame 320 along with the rolled yarn from the spinning tube 310, the stranding frame 320 is placed on the central shaft 41, so that each support rod 45 passes through the inside of the rolled yarn. Then, by pushing the sliding rod 42 to slide relative to the central shaft 41, the first arm 43 and the second arm 44 interact, causing each support rod 45 to move away from the central shaft 41. When each support rod 45 exceeds the support bar 322 of the stranding frame 320, the support rod 45 will open the rolled yarn wound on each support bar 322 outward. It should be noted that because the yarn is elastic, the yarn will not collapse or become tangled during the process of the support rod 45 opening the rolled yarn. In this way, when the rolled yarn is opened by each support rod 45 and detaches from each support bar 322, the stranding frame 320 can be removed from the central shaft 41, thus allowing the rolled yarn to be smoothly separated from the stranding frame 320. At this point, the slide bar 42 slides in the opposite direction relative to the central axis 41, and each support rod 45 retracts until it disengages from the rolled yarn. Thus, the rolled yarn can be smoothly removed from the winding frame 320 by the material handling mechanism 40. It should be noted that because each support rod 45 expands and contracts to remove the rolled yarn from the winding frame 320, the rolled yarn does not experience any sliding friction with the support bars 322 or support rods 45 during this process, effectively preventing problems such as yarn collapse and tangling. In one embodiment, the slide bar 42 can be driven by a linear drive source such as a cylinder or electric cylinder to reciprocate along the axis of the central axis 41, allowing each support rod 45 to move closer or further apart.

[0069] like Figure 9 and Figure 10 As shown, in one embodiment, the support rod 45 includes two rods 45a with a gap between them. Thus, when the stranding frame 320 is fitted onto the central shaft 41, each support bar 322 is located between the two rods 45a of the support rod 45. Therefore, when the support rod 45 is extended outwards, both rods 45a extend outwards simultaneously, thereby simultaneously unwinding the wound yarn from both sides of the support bar 322. This ensures that the wound yarn can smoothly detach from the stranding frame 320.
