Description

Technical Field

[0001] This invention relates to the field of yarn-dyed fabric winding technology, specifically to a wrinkle-resistant winding device for yarn-dyed fabric production. Background Technology

[0002] As an important category in the textile industry that combines aesthetics and practicality, the quality of the winding process directly determines the flatness, color fastness, width consistency, and suitability for subsequent cutting and sewing processes of the finished fabric. In the production of yarn-dyed fabrics, the winding stage requires solving multiple technical challenges, such as fabric wrinkles, uneven tension, heat imbalance, and condensation interference, to meet the refined production needs of high-count, high-density, and multi-material blended yarn-dyed fabrics.

[0003] In the prior art, such as the fabric winding device for yarn-dyed fabric production disclosed in CN215364029U, the fabric is prevented from loosening and wrinkling during the winding process by the cooperation of the connecting frame, pressure roller, fixing rod and buffer spring. However, during the winding process, the fabric is prone to wrinkles due to its own weight, which can lead to the fabric being loose inside and tight outside or misaligned between layers. In addition, the steam nozzles are mostly uniformly distributed and are not designed to differentiate the heating requirements of the middle and edge of the fabric. This makes it difficult for the wrinkles in the middle to be fully smoothed out, or the edges are overheated, resulting in a decrease in color fastness and fiber damage. Summary of the Invention

[0004] To solve the above technical problems, the present invention is achieved through the following technical solution: a wrinkle-resistant winding device for yarn-dyed fabric production, including a support frame, an extension frame at the rear end of the support frame, a front roller, a guide roller and a rear roller arranged sequentially from front to back inside the support frame, the front roller, the guide roller and the rear roller being rotatably connected to the support frame, the front roller being higher than the rear roller, an intermediate roller being rotatably installed inside the support frame near the rear roller, a motor being fixedly connected to the outside of the support frame, the output end of the motor being fixedly connected to the front roller, and the output end of the motor being fixedly connected to the rear roller. The layout of the front roller with high speed and slow speed and the rear roller with low speed and faster speed allows the fabric to maintain a moderate tension during transmission. Combined with the steam heating of the front roller, it can effectively smooth out the original wrinkles of the fabric, and the flatness of the fabric after winding is greatly improved. An intermediate component is arranged inside the support frame, and the intermediate component is located in the gap between the front roller and the guide roller.

[0005] The take-up roller is rotatably mounted on top of the extension frame and is set parallel to the intermediate roller at the same height.

[0006] A square hole is provided on the outer side of the bracket near the guide roller. The square hole completely penetrates the bracket along the axial direction of the guide roller. A spring plate is provided inside the square hole. Under the elastic force of the spring plate, the guide roller is made to make close contact with the yarn-dyed fabric. The two ends of the spring plate are fixedly connected to the end of the guide roller and the inner wall of the square hole, respectively. A flexible hose is fixedly connected to the end face of the guide roller. There are two flexible hoses, which are symmetrically arranged at both ends of the guide roller.

[0007] The front roller includes a connecting tube, which is fixedly connected to a bracket. There are two connecting tubes, and a cylinder is rotatably connected to the outer end of each connecting tube. The two connecting tubes are symmetrically arranged at both ends of the cylinder. The yarn-dyed fabric passes through the front roller, guide roller, rear roller, and intermediate roller in sequence, and is finally wound around the outer side of the take-up roller. At this time, the motor and external motor work, which drive the front roller and rear roller to rotate. The rear roller rotates faster than the front roller. Due to the height difference between the front roller and the rear roller, the fabric hangs down naturally. Combined with the faster speed of the rear roller, the fabric can be tightened, reducing wrinkles during feeding. At the same time, the continuous tension brought by the speed difference makes the fabric adhere more tightly layer by layer on the take-up roller. The speed difference offsets the risk of loosening during fabric transfer, keeping the fabric flat at all times and avoiding loose rolls and misalignment between layers. This makes the tightness of the rolled fabric more uniform inside and out after take-up. The outer side of the cylinder has multiple round holes.

[0008] Preferably, a cover plate is fixedly connected to one end of the cylinder near the connecting pipe. A groove is formed on the side of the cylinder near the cover plate. An arc plate is provided on the outer side of the cylinder near the circular hole. Multiple arc plates are arranged circumferentially on the outer side of the cylinder, which will gather the sprayed steam into the gap between the sleeve and the front roller, forming a local steam atmosphere. The arc plate is in direct contact with the fabric, avoiding direct abrasion of the fabric by the steam hole. When the fabric contacts the outer side of the sleeve, it receives heat through the buffered steam layer. There are multiple arc plates, and two fixing blocks are fixedly connected to the ends of the arc plates. The blocks are symmetrically arranged at both ends of the arc plate, and the fixing blocks are located inside the chutes. There are multiple chutes, divided into two groups, which are symmetrically arranged at both ends of the cylinder. One group of chutes is evenly distributed at one end of the cylinder. The circular holes in the middle of the cylinder are densely arranged, while those on the outer sides of both ends are sparsely arranged. Steam is introduced into the cylinder through a connecting pipe. The steam inside the cylinder is evenly sprayed onto the surface of the yarn-dyed fabric through the circular holes, using the heat and humidity of the steam to process the fabric. The middle of the yarn-dyed fabric is the core area for winding, and the dense arrangement of circular holes in the middle can provide more... Sufficient steam ensures the central part of the fabric is fully heated, while the edge areas require relatively less heat. The widely spaced holes at the ends prevent overheating and damage to the fabric. This achieves precise heating, ensuring sufficient heat in the center and moderate temperature at the edges. A return spring is installed inside the chute, with its two ends fixedly connected to the inner wall of the chute and one end of a fixed block, respectively. A conical block is fixedly connected to the inner side of the arc plate near the cylinder. Utilizing the elastic force of the return spring, when local pressure on the fabric increases, potentially leading to misalignment or stacking, the return spring is compressed, causing adjacent... The reduced gap between the arc plate and the conical block and the round hole reduces the amount of steam, thus decreasing the thermal expansion of the fabric in this area. At the same time, the slight displacement of the arc plate caused by pressure transmission can guide the fabric back to its normal contact trajectory, indirectly suppressing deviation and stacking. By setting the conical block, the steam discharge speed can be controlled by narrowing the gap, preventing steam from going directly from the round hole to the buffer layer, reducing the impact of steam on the fabric, and preventing the color from being washed off by the steam. The end of the conical block away from the arc plate is located inside the round hole, and a spiral plate is fixedly connected inside the cylinder.

[0009] Preferably, the intermediate component includes a partition. Steam released from the front roller through the gap between the circular hole and the arc plate easily diffuses in all directions. The partition forms a barrier between the front roller and the guide roller, confining the steam to the core heating area where the fabric contacts the front roller, reducing steam escape and heat loss. The partition also prevents steam from flowing across the guide roller, protecting its elastic properties and surface friction characteristics, ensuring its long-term stable buffering and guiding function. The partition is fixedly installed inside the bracket, and has through holes. A cleaning plate is fixedly connected to the side of the partition near the front roller, and an inclined plate is fixedly connected to the side of the partition away from the cleaning plate. The pressure block near the inclined plate is magnetically set, and the two pressure blocks have the same magnetism. The yarn-dyed fabric on the front roller passes through the through holes in the partition, with the upper and lower sections... The elliptical pressure block generates continuous extrusion force at the other end due to the repulsion of magnetic poles at one end. The fabric is clamped in both directions during transmission. Combined with the steam heating of the front roller, this extrusion force further relaxes the wrinkles between the fabric fibers, allowing the fabric to form a flat base before entering the guide roller. After winding, the fabric surface is free of wavy lines and local bulges, improving flatness and tightness. The arc-shaped contact surface of the elliptical pressure block has a high degree of fit with the fabric, and the pressure is evenly distributed during extrusion, avoiding fabric indentations caused by local pressure concentration. The inclined plate and cleaning plate are set in parallel, and the inclined plate and cleaning plate clean the outside of the front roller and guide roller respectively. There are two pressure blocks rotatably connected inside the through hole. The two pressure blocks are symmetrically set inside the through hole and are elliptical in shape.

[0010] Preferably, the guide roller includes an intermediate tube located inside a square hole. A slider is fixedly connected to the outside of the intermediate tube, and the slider is connected to the inside of the square hole. A connector is fixedly connected to the end of the intermediate tube. A cylinder is provided on the outside of the end of the connector away from the intermediate tube. There are two connectors and intermediate tubes, which are symmetrically arranged with the cylinder as the center. An intermediate plate is fixedly connected to the middle of the outer side of the cylinder. If condensate seeps into the yarn-dyed fabric fibers, it will cause localized dampness in the fabric. The intermediate plate, cylinder, and side plates are made of rubber. Steam is introduced into the cylinder through the intermediate tube and inner cylinder. The steam then enters the larger diameter end of the conical cylinder and exits from the smaller diameter end of the conical cylinder and the intermediate tube. After the steam flows through the inside of the cylinder, the overall temperature of the guide roller rises and approaches the temperature of the heating area of ​​the front roller. There is no temperature difference condensation condition when the steam contacts the guide roller, avoiding the generation of condensate. At the same time, the guide roller can also dissipate heat to provide secondary constant temperature and moisture retention for the fabric, preventing the fabric from rapidly cooling down and losing water after the front roller is heated. To maintain fiber flexibility and reduce the risk of deformation due to uneven drying and wetting during winding, the intermediate plate is axially arranged, and there are multiple intermediate plates evenly distributed. Side plates are fixedly connected to the outside of the cylinder. The side plates are arc-shaped and there are multiple side plates, which are divided into two groups. The two groups of side plates are symmetrically arranged with the intermediate plate as the center. A conical cylinder is fixedly connected inside the cylinder. The concave structure of the conical cylinder can accelerate the steam flow rate. Combined with the diversion effect of the intermediate plate, it can prevent the steam from forming eddies or dead zones inside the guide roller. The steam can make full contact with the inner wall of the guide roller and then be quickly discharged from the outlet. At the same time, the smooth flow of steam can carry away the trace amount of water vapor inside the guide roller, reducing the risk of steam retention and condensation. This further reduces the possibility of condensation inside the guide roller, thereby avoiding quality defects such as dampness and water stains in the fabric. A guide plate is fixedly connected to the inner wall of the cylinder, and there are multiple guide plates evenly distributed inside the cylinder.

[0011] Preferably, the connecting component includes an inner cylinder rotatably connected to the cylinder body, an outer shell rotatably connected to the outer side of the inner cylinder, the outer shell being fixedly connected to the cylinder body, and the inner cylinder being fixedly connected to a support. A bearing is provided between the inner cylinder and the outer shell. A connecting hole is provided on the outer side of the outer shell, penetrating through the outer shell. A connecting hole is provided inside the inner cylinder near the connecting hole. The connecting hole is L-shaped, and a ring is fixedly connected to the bend of the connecting hole. A middle block is provided inside the ring, and an annular groove is provided in the middle of the outer side of the middle block. When the motor is powered by an external power source, the motor drives the inner cylinder and the cylinder body to rotate. Under the action of centrifugal force, the middle block moves towards the outer shell and slides inside the ring, so that the ring is located at one end of the annular groove on the outer side of the middle block. At this time, the steam inside the cylinder cannot be discharged through the connecting hole and the connecting hole, thus avoiding... To prevent uneven local temperature distribution of the guide rollers due to steam leakage, ensuring a smoother temperature transition during fabric transfer and a more uniform shaping effect, when not in use, the middle block resets under the elastic force of the compression spring. At this time, the steam remaining inside the guide rollers is discharged through the connecting holes and connecting holes, preventing moisture accumulation that could cause rust on the guide roller shaft, bearings, and other metal parts, or hardening of the elastic rubber layer due to long-term moisture aging. A compression spring is fixedly connected to the end of the middle block away from the outer shell, and the end of the compression spring away from the middle block is fixedly connected to the inner wall of the connecting hole. A groove is opened on the inner side of the outer shell, and a convex ring is fixedly connected to the outer side of the inner cylinder. There are multiple grooves and multiple convex rings. Multiple grooves are symmetrically arranged on both sides of the connecting hole, and the convex rings are located inside the grooves. The convex rings and grooves form a sealing structure.

[0012] This invention provides a wrinkle-resistant winding device for yarn-dyed fabric production. It has the following beneficial effects:

[0013] (i) This anti-wrinkle winding equipment for yarn-dyed fabric production uses the height difference between the front roller and the rear roller to allow the fabric to hang naturally. Combined with the faster speed of the rear roller, it can tighten the fabric and reduce wrinkles during feeding. At the same time, the continuous tension brought by the speed difference makes the fabric adhere more tightly layer by layer on the winding roller. The speed difference offsets the risk of loosening during fabric transfer, keeping the fabric flat at all times.

[0014] (ii) The anti-wrinkle winding equipment for yarn-dyed fabric production has a dense arrangement of round holes in the middle of the cylinder and a sparse arrangement of round holes on the outer sides of both ends of the cylinder. This ensures that the middle of the fabric is fully heated and the edge areas at both ends of the fabric have relatively low heat requirements. The sparse arrangement of round holes at both ends can avoid fabric damage caused by overheating at the edges, thus achieving precise heating with sufficient heat in the middle and appropriate temperature at the edges.

[0015] (III) The anti-wrinkle winding equipment for yarn-dyed fabric production uses two elliptical pressure blocks at the top and bottom. Under the action of magnetic repulsion at one end, the other end generates continuous extrusion force. This extrusion force can further relax the wrinkles between the fabric fibers, so that the fabric has formed a flat base before entering the guide roller. After winding, the fabric surface is free of wavy lines and local protrusions, and the flatness and tightness are improved.

[0016] (iv) The anti-wrinkle winding equipment for yarn-dyed fabric production can accelerate the steam flow rate through the conical shrinkage structure. Combined with the diversion effect of the intermediate plate, it avoids the formation of eddies or dead zones in the steam inside the guide roller. The steam can be fully contacted with the inner wall of the guide roller and then quickly discharged from the outlet. At the same time, the smooth flow of steam can carry away the trace amount of water vapor inside the guide roller, reduce the risk of steam retention and condensation, and further reduce the possibility of condensation inside the guide roller. This can avoid quality defects such as dampness and water stains in the fabric. Attached Figure Description

[0028] 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.

[0029] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution: a wrinkle-resistant winding device for yarn-dyed fabric production, including a support 1, an extension frame at the rear end of the support 1, a front roller 3, a guide roller 4 and a rear roller 5 arranged sequentially from front to back inside the support 1, the front roller 3, the guide roller 4 and the rear roller 5 being rotatably connected to the support 1, the front roller 3 being higher than the rear roller 5, an intermediate roller 6 being rotatably installed inside the support 1 near the rear roller 5, a motor 10 being fixedly connected to the outside of the support 1, and a motor 11 being fixedly connected to the outside of the support 1, the output end of the motor 11 being fixedly connected to the front roller 3, and the output end of the motor 10 being fixedly connected to the rear roller 5. The layout of the front roller 3 being high speed and slow speed, and the rear roller 5 being low speed and faster speed, allows the fabric to maintain a moderate tension during transmission. Combined with the steam heating of the front roller 3, it can effectively smooth out the original wrinkles of the fabric, and the flatness of the fabric is greatly improved after winding. An intermediate component 2 is arranged inside the support 1, and the intermediate component 2 is located at the interval between the front roller 3 and the guide roller 4.

[0030] The take-up roller 7 is rotatably mounted on the top of the extension frame, and is set parallel to the intermediate roller 6 at the same height.

[0031] A square hole 8 is provided on the outer side of the bracket 1 near the guide roller 4. The square hole 8 completely penetrates the bracket 1 along the axial direction of the guide roller 4. A spring plate 9 is provided inside the square hole 8. The two ends of the spring plate 9 are fixedly connected to the end of the guide roller 4 and the inner wall of the square hole 8, respectively. A flexible hose 12 is fixedly connected to the end face of the guide roller 4. There are two hoses 12, and the two hoses 12 are symmetrically arranged at both ends of the guide roller 4.

[0032] The front roller 3 includes a connecting pipe 31, which is fixedly connected to the bracket 1. There are two connecting pipes 31, and a cylinder 32 is rotatably connected to the outer end of each connecting pipe 31. The two connecting pipes 31 are symmetrically arranged at both ends of the cylinder 32. The yarn-dyed fabric passes sequentially through the front roller 3, guide roller 4, rear roller 5, and intermediate roller 6, and is finally wound around the outer side of the take-up roller 7. At this time, the motors 11 and 10 are externally connected and work, causing the motors 11 and 10 to drive the front roller 3 and rear roller 5 to rotate. The rear roller 5 rotates faster than the front roller. The high rotation speed of roller 3, due to the height difference between the front roller 3 and the rear roller 5, allows the fabric to hang naturally. Combined with the faster speed of the rear roller, it can tighten the fabric and reduce wrinkles during feeding. At the same time, the continuous tension brought by the speed difference makes the fabric adhere more tightly layer by layer on the winding roller. The speed difference offsets the risk of loosening during fabric transfer, keeping the fabric flat at all times and avoiding loose rolls and misalignment between layers. This makes the tightness of the rolled fabric more uniform inside and outside after winding. The outer side of the cylinder 32 is provided with multiple round holes 38.

[0033] A cover plate 33 is fixedly connected to one end of the cylinder 32 near the connecting pipe 31. A groove 310 is provided on the side of the cylinder 32 near the cover plate 33. An arc plate 34 is provided on the outer side of the cylinder 32 near the circular hole 38. Multiple arc plates 34 are arranged circumferentially on the outer side of the cylinder 32, which will gather the sprayed steam in the gap between the sleeve and the front roller to form a local steam atmosphere. The arc plates 34 are in direct contact with the fabric, avoiding the steam hole from directly scraping the fabric. When the fabric contacts the outer side of the sleeve, it receives heat through the buffer steam layer. There are multiple arc plates 34, and two fixing blocks 35 are fixedly connected to the ends of the arc plates 34. Blocks 35 are symmetrically arranged at both ends of the arc plate 34. The fixing blocks 35 are located inside the slide grooves 310. There are multiple slide grooves 310, divided into two groups. The two groups of slide grooves 310 are symmetrically arranged at both ends of the cylinder 32. One group of slide grooves 310 is evenly distributed at one end of the cylinder 32. The circular holes 38 located in the middle of the cylinder 32 are densely arranged, while the circular holes 38 located on the outer sides of both ends of the cylinder 32 are sparsely arranged. Steam is introduced into the cylinder 32 through the connecting pipe 31. The steam inside the cylinder 32 is evenly sprayed onto the surface of the yarn-dyed fabric through the circular holes 38, utilizing the heat and humidity of the steam to process the fabric. The middle part of the yarn-dyed fabric is the core area for winding. The closely spaced central holes 38 provide ample steam, ensuring sufficient heating of the fabric's center. The lower heat demand at the edges, with more spaced holes 38, prevents overheating and fabric damage, achieving precise heating with adequate heat in the center and suitable temperature at the edges. A return spring 36 is installed inside the slide 310, with its two ends fixedly connected to the inner wall of the slide 310 and one end of the fixing block 35, respectively. A conical block 39 is fixedly connected to the inner side of the arc plate 34 near the cylinder 32. Utilizing the elastic force of the return spring 36, when localized pressure on the fabric increases, potentially leading to misalignment or stacking, the return spring 36... Under compression, the gap between two adjacent arc plates 34 decreases, as does the gap between the conical block 39 and the circular hole 38, resulting in a reduction in the amount of steam. This reduces the thermal expansion of the fabric in this area. At the same time, the slight displacement of the arc plates caused by pressure transmission can guide the fabric back to its normal contact trajectory, indirectly suppressing deviation and stacking. By setting the conical block 39, the steam discharge speed can be controlled by narrowing the gap, preventing steam from going directly from the circular hole 38 to the buffer layer, reducing the impact of steam on the fabric, and preventing the color from being washed off by the steam. The end of the conical block 39 away from the arc plate 34 is located inside the circular hole 38, and a spiral plate 37 is fixedly connected inside the cylinder 32.

[0034] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figure 6As shown, the intermediate component 2 includes a partition 21. Steam released from the front roller 3 through the gap between the circular hole 38 and the arc plate 34 easily diffuses in all directions. The partition 21 forms a barrier between the front roller 3 and the guide roller 4, confining the steam to the core heating area where the fabric contacts the front roller, reducing steam escape and heat loss. The partition 21 also prevents steam from flowing in the direction of the guide roller 4, protecting the elastic properties and surface friction characteristics of the guide roller 4, ensuring its long-term stable buffering and guiding function. The partition 21 is fixedly installed inside the bracket 1. A through hole 22 is provided inside the partition 21. A cleaning plate 25 is fixedly connected to the side of the partition 21 closest to the front roller 3, and an inclined plate 24 is fixedly connected to the side of the partition 21 away from the cleaning plate 25. A pressure block 23 is magnetically set at the end near the inclined plate 24, and the two pressure blocks 23 have the same magnetism. The yarn-dyed fabric on the front roller 3 passes through the through hole 22 on the partition 21. The hole 22 has two elliptical pressure blocks 23. Due to the repulsion of magnetic poles at one end, the other end generates continuous extrusion pressure. The fabric is clamped in both directions during transmission. Combined with the steam heating of the front roller 3, this extrusion pressure can further relax the wrinkles between the fabric fibers, so that the fabric has formed a flat base before entering the guide roller. After winding, the fabric surface is free of wavy lines and local bulges, improving flatness and tightness. The arc-shaped contact surface of the elliptical pressure block 23 has a high degree of fit with the fabric, and the pressure is evenly distributed during extrusion, avoiding fabric indentations caused by local pressure concentration. The inclined plate 24 and the cleaning plate 25 are set in parallel. The inclined plate 24 and the cleaning plate 25 clean the outside of the front roller 3 and the guide roller 4, respectively. The pressure block 23 is rotatably connected inside the through hole 22. There are two pressure blocks 23, which are symmetrically arranged inside the through hole 22. The pressure blocks 23 are elliptical.

[0035] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 7 to 10As shown, the guide roller 4 includes an intermediate tube 41 located inside the square hole 8. A slider 42 is fixedly connected to the outside of the intermediate tube 41. The slider 42 is connected to the inside of the square hole 8. A connector 43 is fixedly connected to the end of the intermediate tube 41. A cylinder 44 is provided on the outer side of the end of the connector 43 away from the intermediate tube 41. There are two connectors 43 and intermediate tubes 41, which are symmetrically arranged with the cylinder 44 as the center. An intermediate plate 46 is fixedly connected to the middle of the outer side of the cylinder 44. If condensate seeps into the interior of the yarn-dyed fabric fibers, it will... This causes localized dampness in the fabric. The middle plate 46, cylinder 44, and side plates 45 are made of rubber. Steam is introduced into the cylinder 44 through the middle pipe 41 and inner cylinder 431. The steam then enters the larger diameter end of the conical cylinder 47 and exits from the smaller diameter end and the middle pipe 41. After the steam circulates throughout the cylinder 44, the overall temperature of the guide roller 4 rises, approaching the temperature of the heating area of ​​the front roller 3. There is no temperature difference causing condensation when the steam contacts the guide roller 4, preventing the formation of condensate. Simultaneously, the guide roller 4 dissipates heat, providing secondary temperature and moisture control for the fabric and preventing the front roller 3 from becoming damp. After heating, the fabric cools down rapidly and loses water, maintaining fiber flexibility and reducing the risk of deformation due to uneven drying during winding. The intermediate plate 46 is axially positioned, and there are multiple intermediate plates 46 evenly arranged. Side plates 45 are fixedly connected to the outer side of the cylinder 44. These side plates 45 are arc-shaped, and there are multiple side plates 45, divided into two groups, symmetrically arranged around the intermediate plate 46. A conical cylinder 47 is fixedly connected inside the cylinder 44. The contraction structure of the conical cylinder 47 accelerates steam flow. In conjunction with the diversion function of the intermediate plate 46, steam is prevented from forming eddies or dead zones inside the guide roller. After the steam comes into full contact with the inner wall of the guide roller 4, it is quickly discharged from the outlet. At the same time, the smooth flow of steam can carry away the trace amount of water vapor inside the guide roller 4, reducing the risk of steam retention and condensation. This further reduces the possibility of condensation inside the guide roller 4, thereby avoiding quality defects such as dampness and water stains on the fabric. The inner wall of the cylinder 44 is fixedly connected with a guide plate 48. There are multiple guide plates 48, which are evenly distributed inside the cylinder 44.

[0036] Connector 43 includes an inner cylinder 431, which is rotatably connected to the cylinder body 44. An outer shell 432 is rotatably connected to the outer side of the inner cylinder 431 and is fixedly connected to the cylinder body 44. The inner cylinder 431 is fixedly connected to the bracket 1. A bearing 433 is provided between the inner cylinder 431 and the outer shell 432. A connecting hole 434 is provided on the outer side of the outer shell 432, penetrating through it. A connecting hole 435 is provided inside the inner cylinder 431 near the connecting hole 434. The connecting hole 435 is L-shaped. A ring 436 is fixedly connected at the turning point. A middle block 437 is provided inside the ring 436. An annular groove 439 is formed in the middle of the outer side of the middle block 437. The motor 10 is connected to an external power source and drives the inner cylinder 431 and the cylinder body 44 to rotate. Under the action of centrifugal force, the middle block 437 moves towards the outer shell 432. The middle block 437 slides inside the ring 436, so that the ring 436 is located at one end of the annular groove 439 on the outer side of the middle block 437. At this time, steam inside the cylinder body 44 cannot pass through. Steam escapes through connecting holes 435 and 434, preventing uneven local temperature on the guide roller 4 due to steam leakage. This ensures a smoother temperature transition during fabric transfer and a more uniform shaping effect. When not in use, the intermediate block 437 resets under the elastic force of the compression spring 438. At this time, the steam remaining inside the guide roller 4 is discharged through connecting holes 435 and 434, preventing moisture accumulation that could cause rust on the guide roller shaft, bearings, and other metal parts, or cause the elastic rubber layer to harden due to long-term moisture exposure. The end of the intermediate block 437 furthest from the outer shell 432... A compression spring 438 is fixedly connected. The end of the compression spring 438 away from the middle block 437 is fixedly connected to the inner wall of the connecting hole 435. A groove 4311 is opened on the inner side of the outer shell 432. A convex ring 4310 is fixedly connected to the outer side of the inner cylinder 431. There are multiple grooves 4311 and multiple convex rings 4310. Multiple grooves 4311 are symmetrically arranged on both sides of the connecting hole 434. The convex ring 4310 is located inside the groove 4311. The convex ring 4310 and the groove 4311 form a sealing structure.

[0037] In use, the yarn-dyed fabric passes sequentially through the front roller 3, guide roller 4, rear roller 5, and intermediate roller 6, and is finally wound around the outside of the take-up roller 7. At this time, the motors 11 and 10 are connected to work externally, causing the motors 11 and 10 to drive the front roller 3 and the rear roller 5 to rotate. The rear roller 5 rotates faster than the front roller 3. Due to the height difference between the front roller 3 and the rear roller 5, the fabric hangs down naturally. Combined with the faster speed of the rear roller, the fabric can be tightened, reducing wrinkles during feeding. At the same time, the continuous tension brought by the speed difference makes the fabric adhere more tightly layer by layer on the take-up roller. The speed difference offsets the risk of loosening during fabric transfer, keeping the fabric flat at all times, avoiding loose rolls and misalignment between layers, and making the tightness of the roll inside and outside more uniform after winding.
