Description

Technical Field

[0001] This invention relates to the field of external winding machine technology, specifically a high-precision fabric external winding machine. Background Technology

[0002] In the textile industry, post-processing machines are a key group of equipment used to improve the quality and function of fabrics after they have been formed. They mainly include drying ovens, fabric roll-out machines, steaming machines, and setting machines. Fabric roll-out machines are key equipment in the textile post-processing stage. They are mainly used to neatly and smoothly roll the woven or dyed fabrics from the production line into large rolls, which facilitates subsequent transportation, storage, and cutting processing.

[0003] Existing fabric roll-up machines are often used for large-diameter fabric winding. For some fabrics with relatively soft surfaces, such as split fabrics, the fabric surface is relatively soft due to its own fuzz. When winding these fabrics, although the fabric tension can be adjusted to wind them normally, the rolled large-diameter fabric is not very tight. This makes such fabrics prone to loosening during subsequent processing. Moreover, for the same roll diameter, the winding length of such fabrics is much shorter than that of other fabrics.

[0004] For example, the aforementioned problems exist in patents (CN121698157A) and (CN221759006U); among them, (CN121698157A) describes "a constant tension machine external winding device comprising: a winding bracket assembly, the winding bracket assembly including a first winding bracket and a second winding bracket disposed opposite to each other; a winding roller, the two ends of the winding roller being respectively connected to a drive shaft and a support shaft through a detachable structure, the drive shaft and the support shaft being respectively disposed opposite to the first winding bracket and the second winding bracket; a driving mechanism, the driving mechanism being driven by the drive shaft..." The device includes: a tension roller that receives the fabric input from the loom and transfers it to the winding roller; and a tension detection mechanism that uses a tension sensor to detect the tension value of the tension roller in real time. The external winding device in the aforementioned patent uses only one tension roller to sense and detect the winding tension of the fabric. Essentially, it is used to adjust the winding tension. However, the winding tension is generally a fixed value or a small range of values. This adjustment method still results in low density of large-diameter fabric rolls when winding soft fabrics with a naturally fuzzy surface. This type of fabric is prone to loosening during subsequent processing, and for fabrics of the same roll diameter, the roll length of this type of fabric is much shorter than that of other fabrics; among them (CN221759006U), it is described as "an external fabric rolling device, including a fabric rolling frame, a vertical frame welded to one side of the top of the fabric rolling frame, a drive motor bolted to one side of the vertical frame, a connecting column connected to the end of the drive motor via a coupling, and a drive wheel welded to the outer wall of the connecting column, a fabric rolling roller welded to one end of the connecting column, and a connecting column movably connected to the inner side of the fabric rolling frame via a bearing, and a movable wheel welded to the outer wall of the connecting column, the connecting..." One end of the column is welded with a pressure roller, and the external transmission connection between the drive wheel and the movable wheel is a drive belt. A stabilizing plate is welded to one side of the fabric roll frame, and a steering motor is bolted to the top of the stabilizing plate. In the above-mentioned patent, the external fabric roll device, although the pressure roller and the movable roller can squeeze and transport the rolled fabric, are far away from the roll roll. This does not help much in terms of the tightness of the rolled fabric outside the roll roll. There is still a problem of low tightness of large-diameter fabric, which makes such fabric easy to become loose during subsequent processing. Moreover, for the same roll diameter, the roll length of such fabric is much shorter than that of other fabrics.

[0005] To address the aforementioned issues with some fabrics having relatively soft surfaces, while adjusting the fabric tension can enable normal winding, the large-diameter rolls of fabric are not tightly wound, leading to loosening during subsequent processing. Furthermore, for fabrics of the same diameter, the winding length of these fabrics is much shorter than that of other fabrics. Therefore, we propose a high-precision fabric external winding machine.

[0009] Furthermore, the clamping roller assembly includes a first clamping roller and a second clamping roller. Both ends of the first clamping roller and the second clamping roller are respectively provided with rotatably connected bearing seats. The bearing seats at both ends of the first clamping roller are fixedly connected to the inner wall of the clamping roller assembly. The second clamping roller is located below the first clamping roller. The clamping roller assembly is symmetrically provided with first linear drive components at both ends. The output ends of the first linear drive components are respectively fixedly connected to the bearing seats at both ends of the second clamping roller.

[0010] Furthermore, the first clamping roller and the second clamping roller are both parallel to the take-up roller, and the first clamping roller, the second clamping roller and the pressure roller are arranged in a triangle. The first clamping roller and the second clamping roller have the same outer diameter. The outer diameter of the pressure roller is greater than 1.5 times the outer diameter of the first clamping roller, and the outer diameter of the pressure roller is less than 2.5 times the outer diameter of the first clamping roller.

[0011] Furthermore, the mounting frame has symmetrical swing arms at both ends of its outer wall. The outer wall of the swing arm is rotatably connected to the inner wall of the first support frame. The end of the swing arm away from the mounting frame is hinged to a first telescopic adjustment component. The end of the first telescopic adjustment component away from the swing arm is rotatably connected to the inner wall of the first support frame.

[0012] Furthermore, the first top roller mechanism and the second top roller mechanism have the same structure. The first top roller mechanism includes a second support frame. The top of the second support frame is provided with a swingable and adjustable Y-shaped frame. Both ends of the upper side of the Y-shaped frame are respectively provided with rotatably connected top rollers. The top rollers are parallel to the take-up roller.

[0013] Furthermore, the second support frame is provided with a fixed shaft at the top, the fixed shaft is parallel to the winding roller, the Y-shaped frame is rotatably sleeved on the outer wall of the fixed shaft, and a second telescopic adjustment component is hinged to one end of the lower side of the Y-shaped frame, the end of the second telescopic adjustment component away from the Y-shaped frame is rotatably connected to the inner wall of the second support frame.

[0014] Furthermore, the second support frame has an L-shaped structure, with the bottom horizontal section of the second support frame located near the take-up roller, and the fixed shaft fixedly located at the top of the vertical section of the second support frame.

[0015] Furthermore, the support base has symmetrically slidably connected connecting plates on both sides of its top, and a rack is horizontally provided on the adjacent side of the bottom of the two connecting plates. A rotatably connected gear is provided at the top center of the support base, and two racks are respectively provided on both sides of the gear. The gear is meshed with both racks. A gear rotation drive mechanism is provided at the bottom center of the support base. The first top roller mechanism and the clamping roller mechanism are fixedly provided on the top of one connecting plate, and the second top roller mechanism is fixedly provided on the top of the other connecting plate. Several second linear drive components are vertically provided at the bottom of the support base.

[0016] Furthermore, the bottom of the connecting plate is provided with several sliders, and the top of the support base is provided with a guide rail that matches the sliding of the sliders. The guide rail and the rack are parallel to each other, and the guide rail is perpendicular to the take-up roller.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are: This invention, through the configuration of a winding machine, a winding and tightening frame, a support base, a first top roller mechanism, a second top roller mechanism, and a clamping roller mechanism, tightens the wound fabric below the winding roller, ensuring the fabric is wound in a compressed and tightened state, effectively enhancing the tightness of the fabric during the winding process. The first top roller mechanism, the second top roller mechanism, and the clamping roller mechanism work together to clamp and compress the wound fabric from both sides below the winding roller, effectively improving the tightness of the fabric during winding and achieving high-precision winding. Especially for soft fabrics with a fuzzy surface, this invention effectively prevents the fabric from becoming loose during subsequent processing, ensuring that for fabrics of the same roll diameter, the winding length of this type of fabric is significantly longer than that of other fabrics. Approximately; the lifting and adjusting of the support base can drive the first top roller mechanism, the second top roller mechanism, and the clamping roller mechanism to perform overall lifting and adjusting. The first top roller mechanism, the second top roller mechanism, and the clamping roller mechanism can perform overall lifting and adjusting movements according to the change of roll diameter, ensuring that the fabric can be clamped and compressed and pressed tightly throughout the entire winding process, ensuring the tightness of the fabric throughout the winding process, and preventing the fabric from loosening and deforming during the winding process; the positions of the first top roller mechanism, the second top roller mechanism, and the clamping roller mechanism can be horizontally adjusted according to the change of the fabric winding roll diameter, ensuring that the coverage of clamping and pressing compression can be adjusted according to the roll diameter range, thereby ensuring the tightness of clamping and pressing compression during the winding process of large-diameter fabric.

[0018] In this invention, the fabric first passes through the inside of the clamping roller assembly of the clamping roller mechanism. After being clamped and compressed by the clamping roller assembly, the fabric then wraps around the pressure roller and onto the take-up roller. The fabric processed by the clamping roller mechanism undergoes a first clamping and compression process inside the clamping roller assembly, and a second clamping and compression process between the pressure roller and the take-up roller. The fabric processed by the clamping roller mechanism is essentially double-compressed before being wound onto the surface of the take-up roller, which effectively improves the tightness of the fabric winding process. By setting a first top roller mechanism... The system includes a second support frame, a Y-shaped frame, and top rollers. The two top rollers on the upper side of the Y-shaped frame press and compress the fabric at two positions on the same side outside the take-up roller. The swing adjustment of the Y-shaped frame can adjust the swing of the top rollers, thereby adjusting the contact position and pressing force of the fabric outside the top roller and the take-up roller. The first and second top roller mechanisms work together to press and compress the fabric outside the take-up roller at four positions, which can effectively improve the tightness of the fabric winding and achieve high-precision fabric winding.

[0020] 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.

[0021] Example 1 Please see Figures 1-7This invention provides a technical solution: a high-precision fabric outer winding machine, comprising a winding machine 1 and a winding and tightening frame 2. The winding and tightening frame 2 is disposed below the winding roller 101 of the winding machine 1. The winding and tightening frame 2 includes a liftable support base 3. The top of the support base 3 is provided with a horizontally adjustable first top roller mechanism 4, a second top roller mechanism 5, and a clamping roller mechanism 6. The first top roller mechanism 4 and the second top roller mechanism 5 are symmetrically disposed on both sides of the top of the support base 3. Between the top roller mechanism 5 and the clamping roller mechanism 6; the clamping roller mechanism 6 includes a first support frame 601, and the top of the first support frame 601 near the first top roller mechanism 4 is provided with a swingable and adjustable mounting frame 602. The inner side of the mounting frame 602 is provided with a clamping roller assembly 603 and a pressure roller 604. Both ends of the pressure roller 604 are rotatably connected to the inner wall of the mounting frame 602. The pressure roller 604 is located between the take-up roller 101 and the clamping roller assembly 603. The pressure roller 604 is connected to the take-up roller 101 and the clamping roller assembly 603. Rollers 101 are parallel to each other; the clamping roller assembly 603 includes a first clamping roller 605 and a second clamping roller 606. Both ends of the first clamping roller 605 and the second clamping roller 606 are respectively provided with rotatably connected bearing seats 607. The bearing seats 607 at both ends of the first clamping roller 605 are fixedly connected to the inner wall of the clamping roller assembly 603. The second clamping roller 606 is located below the first clamping roller 605. The clamping roller assembly 603 is symmetrically provided with a first linear drive assembly 608 at both ends. The output ends of the first linear drive assembly 608 are respectively fixedly connected to the bearing seats 607 at both ends of the second clamping roller 606. The outer wall of the mounting frame 602 is symmetrically provided with swing arms 610 at both ends. The outer wall of the swing arm 610 is rotatably connected to the inner wall of the first support frame 601. The end of the swing arm 610 away from the mounting frame 602 is hinged to a first telescopic adjustment assembly 609. The end of the first telescopic adjustment assembly 609 away from the swing arm 610 is rotatably connected to the inner wall of the first support frame 601.

[0022] In one embodiment, the first clamping roller 605 and the second clamping roller 606 are both parallel to the take-up roller 101, ensuring that the first clamping roller 605 and the second clamping roller 606 clamp the fabric at a position parallel to the take-up roller 101; the first clamping roller 605, the second clamping roller 606, and the pressure roller 604 are arranged in a triangle; the first clamping roller 605 and the second clamping roller 606 have the same outer diameter, the outer diameter of the pressure roller 604 is greater than 1.5 times the outer diameter of the first clamping roller 605, and the outer diameter of the pressure roller 604 is less than 2.5 times the outer diameter of the first clamping roller 605; the first clamping roller 605, the second clamping roller 606, and the pressure roller 604 are arranged in a triangle. The rollers 604 are arranged in a triangular pattern to clamp and flatten the fabric, preventing the first clamping roller 605, the second clamping roller 606, and the pressure roller 604 from being arranged in a straight line outside the take-up roller 101. By limiting the dimensions of the first clamping roller 605, the second clamping roller 606, and the pressure roller 604, the pressure roller 604 is always the closest to the take-up roller 101, regardless of how the mounting frame 602 swings and adjusts. This ensures that the pressure roller 604 always presses and winds the fabric tightly around the outside of the take-up roller 101, thus guaranteeing the tightness of the fabric winding.

[0023] Working principle of the invention: Refer to the instruction manual appendix Figures 1-7 This invention comprises a winding machine 1, a winding and tightening frame 2, a support base 3, a first top roller mechanism 4, a second top roller mechanism 5, and a clamping roller mechanism 6. The winding machine 1 serves as the main structural support for the fabric winding machine, undertaking the function of winding the fabric. The winding and tightening frame 2, located below the winding roller 101, tightens the wound fabric, ensuring it is wound in a compressed and tightened state, effectively enhancing the tightness of the fabric winding process. The support base 3 supports the first top roller mechanism 4, the second top roller mechanism 5, and the clamping roller mechanism 6. The first top roller mechanism 4 and the second top roller mechanism 5, located on both sides below the winding roller 101, perform compression and tightening of the wound fabric, enabling... Effectively improves the tightness of the fabric winding process; the clamping roller mechanism 6 clamps and compresses the wound fabric on the outside below the take-up roller 101, which can effectively improve the tightness of the fabric winding process; the first top roller mechanism 4, the second top roller mechanism 5 and the clamping roller mechanism 6 work together to clamp and compress the wound fabric on both sides below the take-up roller 101, which can effectively improve the tightness of the fabric winding process and achieve high-precision fabric winding; especially for soft fabrics with a fuzzy surface, it can effectively avoid the problem of the fabric becoming loose during subsequent processing, so that the winding length of this type of fabric is similar to that of other fabrics of the same roll diameter; The lifting and adjusting mechanism of support base 3 can drive the first top roller mechanism 4, the second top roller mechanism 5, and the clamping roller mechanism 6 to perform overall lifting and adjusting, which facilitates the winding of fabrics with different roll diameters. The first top roller mechanism 4, the second top roller mechanism 5, and the clamping roller mechanism 6 can adjust their overall lifting and lowering movement according to the change of roll diameter, ensuring that the fabric can be clamped and compressed and pressed tightly throughout the entire winding process, ensuring the tightness of the fabric throughout the winding process, and preventing the fabric from loosening and deforming during the winding process. The horizontal adjustment movement of the first top roller mechanism 4, the second top roller mechanism 5, and the clamping roller mechanism 6 can adjust the clamping and pressing and pressing position of the fabric, enabling clamping and pressing and pressing treatment at different positions for large roll diameter fabrics. This allows the position of the first top roller mechanism 4, the second top roller mechanism 5, and the clamping roller mechanism 6 to be horizontally adjusted according to the change of the roll diameter of the fabric, ensuring that the coverage of clamping and pressing and pressing can be adjusted with the roll diameter range, thereby ensuring the tightness of clamping and pressing and pressing on large roll diameter fabrics during the winding process. During the fabric winding process, the fabric is first clamped and compressed by the clamping roller mechanism 6, and then wound around the outer wall of the winding roller 101. The first top roller mechanism 4 and the second top roller mechanism 5 respectively clamp and compress the fabric wound on the winding roller 101 on both sides below the winding roller 101. The first support frame 601 provides overall support for the clamping roller mechanism 6, and the mounting frame 602 provides mounting support for the clamping roller assembly 603 and the pressure roller 604. Before the fabric enters the outside of the take-up roller 101 for winding, the fabric first passes through the inside of the clamping roller assembly 603 of the clamping roller mechanism 6. After being clamped and compressed by the clamping roller assembly 603, the fabric then passes around the pressure roller 604 and is wound onto the take-up roller 101. In the above working process, the clamping roller mechanism 6 first performs clamping and compression treatment on the fabric. This process compresses the surface pile of the fabric, and then the fabric is pressed and wound up between the pressure roller 604 and the take-up roller 101. The fabric processed by the clamping roller mechanism 6 undergoes a first clamping and compression process inside the clamping roller assembly 603, and a second clamping and compression process between the pressure roller 604 and the take-up roller 101. The fabric processed by the clamping roller mechanism 6 is essentially wound onto the surface of the take-up roller 101 after undergoing double compression, which can effectively improve the tightness of the fabric during the winding process. The swing adjustment of the mounting frame 602 can adjust the swing of the clamping roller assembly 603 and the pressure roller 604, adjust the distance between the mounting frame 602 and the take-up roller 101, and thus adjust the position of the pressure roller 604, so that the pressure roller 604 can compress and press fabrics of different roll diameters. At the same time, the pressing force of the pressure roller 604 on the fabric can be adjusted. The first clamping roller 605 and the second clamping roller 606 cooperate to clamp and compress the fabric. The bearing seats 607 at both ends of the first clamping roller 605 ensure the rotational movement of the first clamping roller 605, and at the same time ensure the fixed relative position between the first clamping roller 605 and the pressure roller 604. The bearing seats 607 at both ends of the second clamping roller 606 ensure the rotational movement of the second clamping roller 606, thereby ensuring rolling contact between the fabric and the first clamping roller 605 and the second clamping roller 606, and ensuring the normal coiling work of the fabric; The first linear drive assembly 608 pushes the second clamping roller 606 located below towards the first clamping roller 605. With such a design, the first linear drive assembly 608 is located at the lower side of the clamping roller assembly 603, making the first linear drive assembly 608 far away from the coiling roller 101, avoiding contact between the first linear drive assembly 608 and the coiled fabric on the outer side of the coiling roller 101 during the swing adjustment of the clamping roller assembly 603; The swing arm 610 of the mounting frame 602 supports the mounting frame 60 to swing. The first telescopic adjustment assembly 609 performs telescopic movement adjustment, enabling swing adjustment of the swing arm 610, and further enabling swing adjustment of the mounting frame 602, thereby enabling swing adjustment of the clamping roller assembly 603 and the pressure roller 604; In the present invention, the structures (such as: the machine frame, the quick roll-changing structure of the coiling roller 101, the drive motor, the reducer, the design of the tension detection structure, the design of the tension adjustment structure, the design of the deviation correction structure, etc.) supporting the coiling machine 1 and the coiling roller 101 can all directly adopt existing mature supporting equipment; the first linear drive assembly 608 and the first telescopic adjustment assembly 609 can be servo electric cylinders, hydraulic cylinders or air cylinders, and specific limitations are not made here. Their synchronous control systems and asynchronous control systems can both be conventionally selected and used according to needs with existing mature control technologies; the rotational and hinged connection methods, lubrication design, sealing design, waterproof design, dust-proof design, etc. between the pressure roller 604 and the mounting frame 602, the first clamping roller 605 and the bearing seat 607, the second clamping roller 606 and the bearing seat 607, the swing arm 610 and the first support frame 601, the first telescopic adjustment assembly 609 and the swing arm 610 can directly adopt existing mature designs. The above contents are all well-known common sense in the art and are not the improvement objects of the present invention. Therefore, no detailed explanation is provided.

[0024] Embodiment 2 Please refer to Figures 1-2 and Figures 7-9The present invention provides a technical solution: a high-precision fabric take-up machine, wherein the first top roller mechanism 4 and the second top roller mechanism 5 have the same structure. The first top roller mechanism 4 includes a second support frame 401, and the top of the second support frame 401 is provided with a swingable and adjustable Y-shaped frame 402. Top rollers 403 are rotatably connected to both ends of the upper side of the Y-shaped frame 402, and the top rollers 403 are parallel to the take-up roller 101. The top of the second support frame 401 is provided with a fixed shaft 404, which is connected to the take-up roller 101. The take-up rollers 101 are parallel to each other. The Y-shaped frame 402 is rotatably sleeved on the outer wall of the fixed shaft 404. A second telescopic adjustment component 405 is hinged to one end of the lower side of the Y-shaped frame 402. The end of the second telescopic adjustment component 405 away from the Y-shaped frame 402 is rotatably connected to the inner wall of the second support frame 401. The second support frame 401 has an L-shaped structure. The bottom horizontal section of the second support frame 401 is located on the side close to the take-up roller 101. The fixed shaft 404 is fixedly located at the top of the vertical section of the second support frame 401.

[0025] In one embodiment, the support base 3 has symmetrically slidably connected connecting plates 301 on both sides of its top. A rack 302 is horizontally arranged on the adjacent side of the bottom of the two connecting plates 301. A rotatably connected gear 303 is located at the center of the top of the support base 3. Two racks 302 are respectively located on both sides of the gear 303, and the gear 303 meshes with both racks 302. A rotation drive mechanism for the gear 303 is located at the center of the bottom of the support base 3. The connecting plates 301 serve as horizontal movement adjustment components, while the racks 302 and gear 303 are the core components for main horizontal movement adjustment, primarily responsible for the conversion between rotational and linear motion. The rotation drive mechanism can drive the gear 303 to perform rotational movement adjustment, and the rotational movement of the gear 303 can drive the two racks 302 to perform linear movement adjustment. The racks 302 drive the connecting plates... The linear motion adjustment of the two connecting plates 301 is performed, with the linear motion directions of the two connecting plates 301 being opposite. The first top roller mechanism 4 and the clamping roller mechanism 6 are fixedly mounted on the top of one connecting plate 301, and the second top roller mechanism 5 is fixedly mounted on the top of the other connecting plate 301. One connecting plate 301 can drive the first top roller mechanism 4 and the clamping roller mechanism 6 to perform horizontal motion adjustment, and the other connecting plate 301 can drive the second top roller mechanism 5 to perform horizontal motion adjustment. The first top roller mechanism 4 and the second top roller mechanism 5 are adjusted to move outward or inward simultaneously under the drive of the two connecting plates 301, so that the first top roller mechanism 4 and the second top roller mechanism 5 are symmetrically positioned below the take-up roller 101 to clamp and compress the fabric during the take-up process. The clamping roller mechanism 6 clamps and compresses the fabric outside the first top roller mechanism 4. The bottom of the support base 3 is vertically provided with several second linear drive components 7. The linear motion adjustment of the second linear drive components 7 can realize the lifting and lowering adjustment of the support base 3.

[0026] In one embodiment, the bottom of the connecting plate 301 is provided with a plurality of sliders 304, and the top of the support base 3 is provided with a guide rail 305 that slides and matches the sliders 304. The guide rail 305 and the rack 302 are parallel to each other, and the guide rail 305 is perpendicular to the take-up roller 101. The sliding cooperation between the sliders 304 and the guide rail 305 can effectively ensure the smoothness and stability of the linear horizontal movement adjustment of the connecting plate 301, thereby ensuring the smoothness and stability of the horizontal movement adjustment of the first top roller mechanism 4, the second top roller mechanism 5 and the clamping roller mechanism 6.

[0027] Working principle of the invention: Refer to the instruction manual appendix Figure 1 and Figures 6-9 The present invention comprises a first top roller mechanism 4 including a second support frame 401, a Y-shaped frame 402, and top rollers 403. The second support frame 401 supports the first top roller mechanism 4, and the Y-shaped frame 402 provides overhead support for the two top rollers 403 on the top of the second support frame 401. The two top rollers 403 on the upper side of the Y-shaped frame 402 respectively apply pressure and compression to the fabric at two positions on the same side outside the take-up roller 101. The Y-shaped support structure of the top rollers 403 ensures that the distance between the two top rollers 403 remains constant and that the swing centers of the two top rollers 403 are the same, so that the two top rollers 403 apply the same pressure force to the fabric outside the take-up roller 101. The lower part of the Y-shaped structure provides a connecting support structure for swing adjustment, facilitating the swing adjustment of the top rollers 403. The swing adjustment of frame 402 can adjust the swing of top roller 403, and adjust the contact position and clamping force of the fabric on the outside of top roller 403 and take-up roller 101. The second top roller mechanism 5 has the same structure as the first top roller mechanism 4. The two top rollers 403 on the second top roller mechanism 5 and the two top rollers 403 on the first top roller mechanism 4 clamp and compress the fabric at two positions on both sides of the outside of take-up roller 101. This allows the first top roller mechanism 4 and the second top roller mechanism 5 to perform clamping and compression treatment on the fabric outside of take-up roller 101 at four positions, which can effectively improve the tightness of the fabric winding and achieve high-precision winding of the fabric. In particular, for soft fabrics with a fluffy surface, it can effectively avoid the problem of the fabric becoming loose during subsequent processing, so that the winding length of this type of fabric is similar to that of other fabrics of the same roll diameter. The fixed shaft 404 provides a swing support position for the Y-shaped frame 402 at the top of the second support frame 401. The telescopic adjustment component 405 can drive the Y-shaped frame 402 to swing by telescopic movement. The Y-shaped frame 402 swings along the fixed shaft 404, thereby driving the two top rollers 403 on the Y-shaped frame 402 to swing and adjust. The second support frame 401 is designed with an L-shaped structure. The bottom horizontal section of the second support frame 401 is located near the take-up roller 101. The fixed shaft 404 is fixedly located at the top of the vertical section of the second support frame 401, so that the second support frame 401 supports the Y-shaped frame 402. This allows the top roller 403 at the end of the Y-shaped frame 402 to easily compress and tighten fabrics of different roll diameters. The horizontal section of the second support frame 401 is mainly used to adapt to changes in the roll diameter of the fabric and to prevent fabrics of different roll diameters from contacting and wearing with the second support frame 401. The second linear drive component 7 can be a servo electric cylinder, hydraulic cylinder, or pneumatic cylinder, without specific limitations. Its synchronous control system and asynchronous control system can be conventionally selected and operated using existing mature control technologies as needed. The rotary drive mechanism can adopt high-precision rotary drive components such as servo motors and geared motors, and its control technology adopts existing conventional mature control technologies. The meshing transmission connection method, lubrication design, waterproof design, and dustproof design of the gear 303 and rack 302 can be adapted to existing conventional mature designs. The rotation and hinge connection method, lubrication design, sealing design, waterproof design, and dustproof design of the fixed shaft and Y-shaped frame 402, the top roller 403 and Y-shaped frame 402, and the second telescopic adjustment component 405 and Y-shaped frame 402 can directly adopt existing mature designs. The above contents are common knowledge in the field and are not the object of improvement of the present invention. Therefore, they are not explained in detail.
