Description

Technical Field

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

[0002] In the yarn production and processing process, the winding process is a key step in neatly winding continuously produced yarn onto a yarn tube or winding roller. The tension of the yarn during the winding process directly determines the forming quality, density uniformity, and subsequent stability of the yarn roll.

[0003] Traditional yarn winding equipment often relies on rigid mechanical components (such as fixed guide rollers or counterweight-type clamping mechanisms) or simple elastic adjustment structures to apply tension to the yarn through preset mechanical pressure or elastic force, thereby achieving basic tension control. For example, patent document CN219620575U discloses a winder for fiber yarn production, which uses limiting parts on both sides of a fixed guide rail to limit and assist in tensioning the yarn. The limiting parts include an arc-shaped cover, a slide rod, a spring, and a pulley. The arc-shaped cover is slidably connected to the fixed guide rail through the slide rod, and the spring is sleeved on the surface of the slide rod. The elastic deformation of the spring allows the pulley to finely adjust its position according to the tilt angle of the yarn, reducing the possibility of the yarn getting stuck or breaking. At the same time, a certain tensioning force is generated by the contact between the pulley and the yarn.

[0004] However, the above-mentioned winder has the following disadvantages when winding large-volume yarns: First, the tensioning force of the aforementioned structure relies on the elastic deformation of the spring, and the spring's elastic force output has the characteristics of short stroke and narrow linear change range of force value. When the winding equipment uses a large-diameter drum, as the number of yarn winding turns increases, the yarn drum diameter will increase significantly, causing the yarn running trajectory tilt angle to change non-linearly and over a large range. At this time, the spring's fine-tuning stroke is far from matching the offset of the yarn trajectory, which easily leads to gaps where the pulley and yarn are not in contact, causing the yarn to loosen, jump, and cause winding misalignment. At the same time, excessive spring compression will cause the elastic force to increase sharply, significantly increasing the yarn winding resistance, which not only easily wears down the yarn surface but may also cause yarn breakage accidents.

[0005] Secondly, the tensioning structure passively adapts to changes in the yarn tilt angle only through the spring. In the actual winding process, factors such as fluctuations in the linear speed of the yarn and uneven material (such as thickness deviation) will cause changes in the actual tension of the yarn. The passive fine adjustment of the spring cannot compensate for these tension fluctuations in real time, which can easily lead to the tension fluctuating, resulting in uneven tension between the inner and outer layers of the yarn roll and affecting the forming quality.

[0006] Therefore, it is necessary to design a tensioning structure for yarn winding equipment that can adapt to large-diameter drum winding conditions, has active tension adjustment capability, and strong tension stability. Utility Model Content

[0007] To solve one of the aforementioned technical problems, the present invention provides a tensioning structure for a yarn winding device, comprising a drum, the axle end of which is connected to the power shaft of the winding device via a key, yarn from upstream being wound on the drum, a fixedly mounted rotary control component installed above the left-side inlet end of the drum, rope-pressing adjustment components installed at the front and rear output ends of the rotary control component, a rope presser installed between the two rope-pressing adjustment components, the bottom of the rope presser abutting against the top of the drum and used to press the yarn, and a yarn guide adjustment mechanism installed on the left side of the rotary control component, the yarn guide adjustment mechanism being used to adjust the angle at which the yarn enters the drum and guide the yarn in the traction state.

[0008] When the external winding equipment is working, it drives the drum to rotate, thereby pulling the upstream yarn to continuously wind onto the drum. During the yarn winding process, the pressure change sensed by the first circular pressure sensor on the rope presser is used to adjust the lifting speed and amplitude of the rope presser, thereby ensuring that the rope presser completes contact limit with the top layer of yarn and prevents the yarn from slipping.

[0009] In addition, as the number of yarn loops wound on the drum increases, the angle at which the yarn on the left enters the drum will change. When the tilt angle is large, it will increase the friction between the yarn and the rope presser. At this time, when the first ring pressure sensor senses the pressure change on the left side, the rope presser adjustment pieces at both ends can be controlled by rotating the control piece to swing synchronously at a preset appropriate angle. The swinging and telescopic cooperation of the two rope presser adjustment pieces can drive the rope presser to swing, thereby achieving the purpose of adjusting the position.

[0010] In addition, the horizontal position of the yarn guide can be adjusted by coordinating the horizontal extension and vertical lifting control of the yarn guide adjustment mechanism, so that it is closer to or further away from the inlet end of the drum. When adjusting vertically, it can be pulled up or down to keep it close to horizontal, so that the entry angle is smaller and the wear of the inlet end and the rope presser is reduced.

[0011] Based on any of the above technical solutions, a further optimization is made as follows: the rotation control component adopts a horizontally and fixedly installed dual-output shaft motor, the dual-output shaft motor is fixedly installed with splines at the ends of the motor shafts at both ends of the dual-output shaft motor, and the rope pressing adjustment component is fixedly installed on the two splines respectively.

[0012] Based on any of the above technical solutions, a further optimization is made as follows: the rope pressing adjustment component includes an inclined adjusting electric cylinder, the end of the cylinder barrel of the adjusting electric cylinder is fixedly installed on the outer side wall of the corresponding spline, and the end of the telescopic end of the adjusting electric cylinder is fixedly connected to the end of the rope pressing device; the two adjusting electric cylinders telescopically extend and retract synchronously when working.

[0013] Based on any of the above technical solutions, a further optimization is made as follows: the rope presser includes a horizontally arranged positioning tube, the two ends of the positioning tube are respectively fixed to the ends of the telescopic ends of the adjusting electric cylinder on their corresponding sides, a first circular pressure sensor is fixedly installed on the outer wall of the positioning tube, and a rope pressing ring is movably sleeved on the outer wall of the first circular pressure sensor, the bottom of the rope pressing ring abuts against the top of the yarn wound on the drum.

[0014] Based on any of the above technical solutions, a further optimization is made as follows: the yarn guiding and adjusting mechanism includes a translation cylinder group horizontally arranged on the left side of the motor housing of the dual output shaft motor. The translation cylinder group consists of two synchronously telescopic horizontal cylinders. Positioning uprights are fixed at the ends of the piston rods of the two horizontal cylinders respectively. The lifting guide is installed between the two horizontal cylinders. The top of the lifting guide is fixedly inserted into the cavity of the corresponding positioning upright.

[0015] Based on any of the above technical solutions, a further optimization is made as follows: the lifting guide includes two vertically spaced lifting cylinders, the two lifting cylinders are respectively inserted into the cavity of the positioning riser and bolted and fixed, the two lifting cylinders are in a synchronous lifting state when working, a positioning plate is fixedly installed at the bottom of the piston rod of each lifting cylinder, the yarn is located between the two positioning plates, and a guide member for clamping the yarn in the middle is installed between the two positioning plates.

[0016] Based on any of the above technical solutions, a further optimization is made as follows: the guide component includes an upper fixed shaft and a lower fixed shaft installed in the space between the two positioning plates and spaced apart from top to bottom. Both ends of the upper fixed shaft and the lower fixed shaft are fixed on the positioning plates. A second annular pressure sensor is sleeved on the outer wall of the upper fixed shaft, and a third annular pressure sensor is sleeved on the outer wall of the lower fixed shaft. An upper guide sleeve is movably sleeved on the outer wall of the second annular pressure sensor, and a lower guide sleeve is movably sleeved on the outer wall of the third annular pressure sensor.

[0017] Based on any of the above technical solutions, a further optimization is made: the first circular pressure sensor, the second circular pressure sensor, and the third circular pressure sensor are all connected to an externally configured pressure display and the existing control box signal.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a first circular pressure sensor on the rope presser to sense pressure changes in real time and dynamically adjust the lifting speed and amplitude of the rope presser. At the same time, it works with a rotary control component to control the swing of the rope presser adjustment component and a yarn guide adjustment mechanism to adjust the yarn entry angle. This can effectively prevent yarn slippage, ensure the regularity and tightness of the yarn winding on the drum, and improve the yarn winding quality.

[0019] 2. This utility model can flexibly adjust the tilt angle of the electric cylinder to change the tension of the rope presser on the yarn according to the characteristics of different types and thicknesses of yarn. It can also adapt to different specifications of yarn by changing the guide parts. At the same time, the yarn tension can be finely adjusted by the lifting cylinder, which greatly improves the adaptability of the equipment to various yarn winding needs.

[0020] 3. This utility model uses a yarn guiding and adjusting mechanism to keep the angle at which the yarn enters the drum nearly horizontal, reducing friction between the yarn and the drum's inlet end and the rope presser. The movable sleeve design of the rope presser ring reduces yarn wear, and the connection structure between the dual output shaft motor and the spline facilitates component maintenance and replacement, effectively extending the service life of the yarn and equipment components and reducing equipment maintenance costs.

[0026] The embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of the present utility model, and are therefore merely examples and should not be construed as limiting the scope of protection of the present utility model. The specific structure of the present utility model is as follows: Figures 1-3 As shown in the image.

[0027] Example 1: A tensioning structure for a yarn winding device includes a drum 1. The axle end of the drum 1 is connected to the power shaft 2 of the winding device via a key. Yarn 3 from upstream is wound on the drum 1. A fixedly installed rotary control component is installed above the left inlet end of the drum 1. Two rope pressing adjustment components are installed at the front and rear output ends of the rotary control component. A rope pressing device is installed between the two rope pressing adjustment components. The bottom of the rope pressing device abuts against the top of the drum 1 and is used to press the yarn 3. A yarn 3 guiding and adjusting mechanism is installed on the left side of the rotary control component. The yarn 3 guiding and adjusting mechanism is used to adjust the angle at which the yarn 3 enters the drum 1 and guide the yarn 3 in the traction state.

[0028] When the external winding equipment is working, it drives the drum 1 to rotate, thereby pulling the upstream yarn 3 to continuously wind around the drum 1. During the winding process of the yarn 3, the pressure change sensed by the first circular pressure sensor 4 set on the rope presser is used to adjust the lifting speed and amplitude of the rope presser, thereby ensuring that the rope presser completes contact limit with the top layer of yarn 3 and prevents the yarn 3 from slipping.

[0029] In addition, as the number of turns of yarn 3 wound on the drum 1 increases, the angle at which the left yarn 3 enters the drum 1 will change. When the tilt angle is large, the friction between the yarn 3 and the rope presser will increase. At this time, when the first ring pressure sensor 4 senses the pressure change on the left side, the rope pressing adjustment parts at both ends can be controlled by rotating the control component to swing synchronously at a preset appropriate angle. The swinging and telescopic cooperation of the two rope pressing adjustment parts can drive the rope presser to swing, thereby achieving the purpose of adjusting the position.

[0030] In addition, the horizontal position of the yarn 3 guide can be adjusted by coordinating the horizontal extension and vertical lifting control of the yarn 3 guide adjustment mechanism, so that it is closer to or further away from the inlet end of the drum 1. When adjusting vertically, it can be pulled up or down to keep it close to horizontal, so that the entry angle is smaller and the wear of the inlet end and the rope presser is reduced.

[0031] First, the drum 1 obtains rotational power through a keyed connection between the wheel axle end and the power shaft of the existing winding equipment. The keyed connection ensures that there is no relative rotation between the drum 1 and the power shaft during power transmission, thus guaranteeing the stability and reliability of power transmission.

[0032] When the winding equipment is started, the power shaft drives the drum 1 to rotate. The traction force generated when the drum 1 rotates will continuously pull the upstream yarn 3 to the surface of the drum 1 and complete the winding.

[0033] Secondly, a rotating control component is fixedly installed above the left side inlet end of the drum 1. The rope pressing adjustment components installed at its front and rear output ends serve to connect the rotating control component and the rope pressing device. The bottom of the rope pressing device abuts against the top of the drum 1 and applies a pressing force to the yarn 3 during the winding process to prevent the yarn 3 from becoming loose during the winding process.

[0034] Finally, the yarn 3 guide adjustment mechanism on the left side of the rotating control component changes the angle at which the yarn 3 enters the drum 1 through its own structural adjustment capability, and guides the yarn 3 in the traction state to ensure that the yarn 3 can enter the drum 1 according to the preset path and angle, thus ensuring the orderliness of the winding process. The rope presser, together with the rope pressing adjustment component and the rotation control component, forms a yarn 3 clamping adjustment structure. The clamping force of the rope presser on the yarn 3 can be flexibly adjusted according to the winding condition of the yarn 3, which is suitable for the winding needs of different types and thicknesses of yarn 3, and improves the versatility of the equipment.

[0035] The yarn 3 guide adjustment mechanism is independently located on the left side of the rotating control component. It works in conjunction with the rope pressing structure without interfering with each other. It can adjust the yarn 3 entry angle and the yarn 3 clamping state separately, so that various parameters of the yarn 3 winding process can be controlled independently, improving the controllability of winding quality. The core function of the yarn 3 guiding and adjusting mechanism is to adjust the angle at which the yarn 3 enters the drum 1, so as to avoid the yarn 3 from getting tangled and messy due to improper entry angle. At the same time, it guides the pulled yarn 3 to ensure the stability of the yarn 3's movement path. The yarn 3 guide adjustment mechanism can reduce the friction between the yarn 3 and the edge of the inlet end of the drum 1 during the process of entering the drum 1 by adjusting the guide position, thereby reducing the wear of the yarn 3, extending the service life of the yarn 3, and also preventing the inlet end of the drum 1 from being damaged due to long-term friction, thus improving the overall service life of the equipment.

[0036] Based on any of the above technical solutions, a further optimization is made as follows: the rotation control component adopts a horizontally and fixedly installed dual-output shaft motor 5, the dual-output shaft motor 5 is fixedly installed with splines 7 at the ends of the motor shafts at both ends of the dual-output shaft motor 5, and the rope pressing adjustment component is fixedly installed on the two splines 7 respectively.

[0037] In this optimized scheme, the rotary control component uses a horizontally and fixedly mounted dual-output shaft motor 5. Its fixed mounting method ensures that the motor will not shift position during operation, providing a stable foundation for subsequent power transmission and motion control.

[0038] The core function of the dual-output shaft motor 5 is to output rotational power. Its front and rear motor shafts serve as power output ends, and the splines 7 fixedly mounted at the ends provide a connection interface for the installation of the rope-pressing adjustment component. When the dual-output shaft motor 5 receives a command from an external control mechanism, the motor shaft drives the splines 7 to rotate synchronously. The splines 7 then drive the rope-pressing adjustment component to swing around the motor shaft axis, achieving angle adjustment of the rope-pressing adjustment component and providing power support for subsequent position adjustment of the rope presser. A dual-output shaft motor 5 is selected as the rotation control component to ensure consistent power supply to the rope-pressing adjustment components at both ends, facilitating synchronous operation. The dual-output shaft motor 5 is horizontally fixed, ensuring that the motor shaft axis is parallel to the swing plane of the rope-pressing adjustment component. This ensures that the swing direction of the rope-pressing adjustment component meets design requirements, avoids deviation of the rope-pressing adjustment component due to improper motor installation angle, and guarantees adjustment accuracy.

[0039] The fixed configuration of the dual-output shaft motor 5 allows it to serve as a stable support structure for the rope-pressing adjustment component during operation. Besides providing power, it also limits the displacement of the rope-pressing adjustment component in the non-oscillating direction, preventing it from shifting due to the lateral force of the yarn 3. This ensures the stability of the rope-pressing adjustment component's operation and indirectly improves the reliability of the rope presser's clamping and limiting of the yarn 3. When the rope-pressing adjustment component malfunctions or is damaged, it can be directly removed and replaced from the spline 7 without disassembling the entire dual-output shaft motor 5, reducing equipment maintenance difficulty and time, and improving equipment maintenance convenience.

[0040] Based on any of the above technical solutions, a further optimization is made as follows: the rope pressing adjustment component includes an inclined adjusting electric cylinder 8, the end of the cylinder of the adjusting electric cylinder 8 is fixedly installed on the outer side wall of the corresponding spline 7, and the end of the telescopic end of the adjusting electric cylinder 8 is fixedly connected to the end of the rope pressing device; the two adjusting electric cylinders 8 extend and retract synchronously when working.

[0041] In this optimized solution, the rope pressing adjustment component adopts an inclined adjustment electric cylinder 8, the end of which is fixedly installed on the outer wall of the spline 7. This installation method makes the adjustment electric cylinder 8 and the spline 7 form a rigid connection. When the spline 7 rotates, it can drive the adjustment electric cylinder 8 to swing around the motor shaft axis.

[0042] The core function of the adjusting electric cylinder 8 is to realize the telescopic action. Its telescopic end is fixedly connected to the end of the rope presser. When the adjusting electric cylinder 8 receives a control command, the telescopic end extends or retracts, driving the rope presser to move along the axis of the adjusting electric cylinder 8, thereby adjusting the distance between the rope presser and the drum 1. At the same time, since the two adjusting electric cylinders 8 extend and retract synchronously when working, it can ensure that the driving force on both ends of the rope presser is uniform, and avoid the rope presser from tilting due to inconsistent extension and retraction at both ends.

[0043] When the dual-output shaft motor 5 drives the spline 7 to rotate, the adjusting electric cylinder 8 swings with the spline 7 and simultaneously coordinates with the synchronous telescopic action, which can realize the angle adjustment and position movement of the rope presser in space, so as to meet the position requirements of the rope presser under different yarn 3 winding states.

[0044] The electric cylinder 8 is tilted so that its extension and retraction direction matches the force direction of the rope presser. When adjusting the position of the rope presser, the clamping force of the rope presser on the yarn 3 can be changed more directly, reducing force loss and improving adjustment efficiency. At the same time, it avoids the rope presser from bearing additional lateral force due to improper adjustment direction, thus extending the service life of the rope presser.

[0045] The synchronous extension and retraction design of the two adjusting electric cylinders 8 ensures that the two ends of the rope presser move synchronously, so that the rope presser always remains in a horizontal state (or a preset angle state), avoiding the rope presser tilting and causing excessive or insufficient local clamping force, ensuring the uniformity of the clamping force of the rope presser on the yarn 3, and further improving the regularity of the yarn 3 winding. The extension and retraction of the adjusting electric cylinder 8 can serve as an emergency protection mechanism for the rope presser. When the first circular pressure sensor 4 senses that the pressure of the rope presser on the yarn 3 exceeds the preset safety threshold (such as when the yarn 3 is wound too tightly or when foreign objects are stuck), the external control mechanism can immediately control the extension and retraction end of the adjusting electric cylinder 8 to retract, moving the rope presser away from the yarn 3, thus preventing the yarn 3 from breaking due to excessive compression or damage to equipment parts, and providing overload protection.

[0046] The tilt angle of the electric cylinder 8 can be preset and adjusted according to the characteristics of different types of yarn 3. For example, for yarn 3 with low elasticity and easy breakage, the tilt angle of the electric cylinder 8 can be set to make the tensioning force of the rope presser on the yarn 3 gentler; for thicker yarn 3 that requires greater tension, the tilt angle can be adjusted to increase the tension, thereby improving the adaptability of the equipment to different yarns 3 and expanding the application range of the equipment.

[0047] Based on any of the above technical solutions, a further optimization is made as follows: the rope presser includes a horizontally arranged positioning tube 9, the two ends of the positioning tube 9 are respectively fixed to the ends of the telescopic ends of the adjusting electric cylinder 8 on their corresponding sides, a first circular pressure sensor 4 is fixedly installed on the outer wall of the positioning tube 9, and a rope pressing ring 10 is movably sleeved on the outer wall of the first circular pressure sensor 4, the bottom of the rope pressing ring 10 abuts against the top of the yarn 3 wound on the drum 1.

[0048] In this optimized design, the core supporting component of the rope presser is a horizontally positioned positioning tube 9, with both ends fixed to the telescopic ends of the corresponding side adjusting cylinder 8. The horizontal positioning of the positioning tube 9 ensures the stability of the overall structure of the rope presser and provides an installation base for the first annular pressure sensor 4 and the rope pressing ring 10. The first annular pressure sensor 4 is fixedly installed on the outer wall of the positioning tube 9, with its inner side fixed to the positioning tube 9 and its outer side movably sleeved with the rope pressing ring 10. This structure allows the pressure generated by the rope pressing ring 10 when it abuts against the yarn 3 to be directly transmitted to the first annular pressure sensor 4.

[0049] When yarn 3 is wound onto the drum 1, the bottom of the pressure ring 10 abuts against the top of the yarn 3. The yarn 3 generates an upward reaction force on the pressure ring 10, which is transmitted to the first circular pressure sensor 4. The first circular pressure sensor 4 converts the pressure signal into an electrical signal and transmits it to the external control mechanism. Since the pressure ring 10 is movably sleeved on the outside of the first circular pressure sensor 4, it can rotate or move slightly with the slight undulations of the yarn 3 surface during the winding process, ensuring that the pressure ring 10 always maintains good contact with the yarn 3 surface and avoiding inaccurate pressure sensing due to unevenness of the yarn 3 surface. The first circular pressure sensor 4 is fixedly installed between the positioning tube 9 and the pressure ring 10. The pressure transmission path is short and direct, reducing pressure loss and ensuring that the pressure sensor can accurately sense the reaction force of the yarn 3 on the pressure ring 10, thereby improving the pressure monitoring accuracy.

[0050] The pressure ring 10 is movably sleeved on the outside of the first circular pressure sensor 4, giving the pressure ring 10 a certain degree of freedom of movement, so that it can adapt to the unevenness of the yarn 3 surface, avoid local gaps or excessive compression between the pressure ring 10 and the yarn 3, ensure the uniformity of the pressure force of the pressure ring 10 on the yarn 3, and at the same time reduce the friction between the pressure ring 10 and the yarn 3, and reduce the wear of the yarn 3.

[0051] The core function of the first circular pressure sensor 4 is to sense the reaction force of the yarn 3 transmitted by the rope pressing ring 10, convert the pressure signal into an electrical signal, and realize real-time monitoring of the rope pressing force.

[0052] The movable sleeve structure of the pressure rope ring 10 can act as a buffer when yarn 3 breaks. When yarn 3 suddenly breaks, the pressure rope ring 10 loses the support of yarn 3 and moves downward under the action of gravity. Due to its movable sleeve characteristic, the pressure rope ring 10 can avoid instantaneous impact on the first circular pressure sensor 4 or the positioning tube 9, reducing the risk of component damage. At the same time, the first circular pressure sensor 4 senses the sudden drop in pressure and can send a yarn breakage signal to the control mechanism in a timely manner, which facilitates the timely shutdown of the equipment and reduces subsequent failures.

[0053] Based on any of the above technical solutions, a further optimization is made as follows: the yarn 3 guiding and adjusting mechanism includes a translation cylinder group horizontally arranged on the left side of the motor housing of the dual output shaft motor 5. The translation cylinder group consists of two synchronously telescopic horizontal cylinders 11. Positioning risers 12 are fixed to the ends of the piston rods of the two horizontal cylinders 11 respectively. The lifting guide is installed between the two horizontal cylinders 11. The top of the lifting guide is fixedly inserted into the cavity of the corresponding positioning riser 12.

[0054] In this optimized scheme, the horizontal adjustment function of the yarn 3 guide adjustment mechanism is realized by the translation cylinder group. The translation cylinder group is horizontally set on the left side of the motor housing of the dual output shaft motor 5. Its position setting ensures that the adjustment action of the translation cylinder group will not interfere with the rope pressing structure. At the same time, it is close to the yarn inlet end of the drum 1, which facilitates the adjustment of the yarn 3 entry path.

[0055] The translation cylinder assembly consists of two synchronously telescopic horizontal cylinders 11. The synchronous operation of the two horizontal cylinders 11 ensures that the positioning riser 12, which is fixed at the end of its piston rod, moves synchronously, preventing the positioning riser 12 from shifting. The core function of the positioning riser 12 is to provide an installation interface and support for the lifting guide. Its cavity structure provides space for the fixed insertion at the top of the lifting guide. Through the fixed insertion method, it is ensured that there is no relative movement between the lifting guide and the positioning riser 12, thus improving the stability of the lifting guide.

[0056] When the translation cylinder assembly receives a control command, the piston rod of the horizontal cylinder 11 extends or retracts, driving the positioning riser 12 to move horizontally. The positioning riser 12 then drives the lifting guide to move horizontally synchronously, thereby adjusting the horizontal position of the lifting guide and changing the guiding path of the yarn 3 in the horizontal direction. At the same time, the lifting guide can achieve vertical lifting and lowering movements with the support of the positioning riser 12, which, in conjunction with the horizontal adjustment, together completes the adjustment of the entry angle of the yarn 3. The yarn 3 guide adjustment mechanism is set on the left side of the dual output shaft motor 5, maintaining a reasonable distance from the rope pressing structure. This avoids interference between the two during operation, ensuring smooth horizontal and vertical adjustment. At the same time, it makes the yarn 3 guide path closer to the yarn inlet end of the drum 1, resulting in a more direct adjustment effect and improving the adjustment efficiency of the yarn 3 entry angle. The core function of the positioning riser 12 is to connect the horizontal cylinder 11 and the lifting guide, transmit the power of the horizontal cylinder 11, drive the lifting guide to move horizontally, and at the same time provide vertical installation support and guidance for the lifting guide to ensure the stability of the vertical movement of the lifting guide.

[0057] The core function of the lifting guide is to achieve vertical lifting under the support of the positioning riser 12, change the guiding path of the yarn 3 in the vertical direction, and adjust the entry angle of the yarn 3 in conjunction with the horizontal adjustment. Based on any of the above technical solutions, a further optimization is made as follows: the lifting guide includes two vertically spaced lifting cylinders 13, the two lifting cylinders 13 are respectively inserted into the cavity of the positioning riser 12 and bolted and fixed, the two lifting cylinders 13 are in a synchronous lifting state when working, a positioning plate 14 is fixedly installed at the bottom of the piston rod of each lifting cylinder 13, the yarn 3 is located between the two positioning plates 14, and a guide member for clamping the yarn 3 in the middle is installed between the two positioning plates 14.

[0058] In this optimized scheme, the vertical adjustment power of the lifting guide is provided by two vertically spaced lifting cylinders 13. The two lifting cylinders 13 are respectively inserted into the cavity of the positioning riser 12 and fixed by bolting. The bolting method ensures that the connection between the lifting cylinder 13 and the positioning riser 12 is firm and there is no relative movement, which provides a basis for the stable lifting of the lifting cylinder 13.

[0059] When the two lifting cylinders 13 are working, they lift and lower synchronously, which can ensure that the positioning plate 14 fixed at the bottom of its piston rod moves vertically synchronously, and prevent the positioning plate 14 from tilting due to asynchronous lifting and lowering.

[0060] The guide installed between the two positioning plates 14 can clamp the yarn 3 in the middle, which can limit and guide the yarn 3, and ensure that the yarn 3 always moves along the preset path during the traction process.

[0061] When the lifting cylinder 13 receives an external control command, the piston rod extends or retracts, causing the positioning plate 14 and the guide to move vertically in sync. The guide then causes the clamped yarn 3 to change its vertical position. In conjunction with the horizontal adjustment of the translation cylinder group, precise control of the angle at which the yarn 3 enters the drum 1 is achieved.

[0062] The use of two synchronously lifting cylinders 13 provides vertical power to the positioning plate 14 and guide components from both sides, compared to a single lifting cylinder 13. This ensures that the positioning plate 14 is subjected to uniform force during lifting, preventing tilting of the positioning plate 14 due to force on one side. It also ensures stable clamping and guiding position of the guide components on the yarn 3, and improves the accuracy of vertical adjustment.

[0063] The two positioning plates 14 cooperate with the guide to form a yarn 3 clamping and guiding structure, which can ensure that the yarn 3 does not deviate from the preset path during the guiding process, and avoid damage to the yarn 3 due to excessive clamping force. It achieves a balance between guiding stability and yarn 3 protection, and improves the winding quality of the yarn 3. The core function of the guide is to clamp the yarn 3 in the middle, limit and guide the yarn 3, ensure that the yarn 3 moves along the preset path during the pulling process, avoid the yarn 3 swinging or deviating, and ensure that the path of the yarn 3 entering the drum 1 is stable. When the tension of yarn 3 is too low, the lifting cylinder 13 can be controlled to appropriately lower the position of the guide to increase the path length of yarn 3 between the guide and the drum 1, thereby indirectly increasing the tension of yarn 3 by extending the path; when the tension of yarn 3 is too high, the position of the guide can be raised to shorten the path length and reduce the tension of yarn 3, thereby achieving fine adjustment of the tension of yarn 3 and improving the stability of yarn 3 winding.

[0064] The detachable connection between the guide and the positioning plate 14 makes it easy to replace the guide with a suitable one according to the different thicknesses of yarn 3.

[0065] For example, for finer yarns 3, the guide with a smaller clamping gap can be replaced to ensure the guiding effect; for coarser yarns 3, the guide with a larger clamping gap can be replaced to avoid the yarns 3 being over-compressed and to improve the equipment's adaptability to yarns 3 of different specifications.

[0066] Example 2: Compared with Example 1, this example also includes the following technical features: Based on any of the above technical solutions, a further optimization is made as follows: the guide component includes an upper fixed shaft 15 and a lower fixed shaft 16 installed in the space between the two positioning plates 14 and spaced apart from top to bottom. Both ends of the upper fixed shaft 15 and the lower fixed shaft 16 are fixed on the positioning plates 14. A second annular pressure sensor 17 is sleeved on the outer wall of the upper fixed shaft 15, and a third annular pressure sensor 18 is sleeved on the outer wall of the lower fixed shaft 16. An upper guide sleeve 19 is movably sleeved on the outer wall of the second annular pressure sensor 17, and a lower guide sleeve 20 is movably sleeved on the outer wall of the third annular pressure sensor 18.

[0067] In this optimized solution, the guide component adopts a double-layer shaft structure of upper fixed shaft 15 and lower fixed shaft 16. The two are installed in the space between two positioning plates 14 from top to bottom, and both ends are fixed on the positioning plates 14. The fixed installation method ensures that the upper fixed shaft 15 and lower fixed shaft 16 do not shift during operation.

[0068] The second annular pressure sensor 17, sleeved on the outer wall of the upper fixed shaft 15, and the third annular pressure sensor 18, sleeved on the outer wall of the lower fixed shaft 16, primarily function to sense pressure changes between the yarn 3 and the guide sleeve. The upper guide sleeve 19 is movably sleeved on the outside of the second annular pressure sensor 17, and the lower guide sleeve 20 is movably sleeved on the outside of the third annular pressure sensor 18. This movable sleeve structure allows the upper guide sleeve 19 and the lower guide sleeve 20 to rotate around their respective fixed shafts.

[0069] When yarn 3 passes between the upper guide sleeve 19 and the lower guide sleeve 20, yarn 3 contacts the upper guide sleeve 19 and the lower guide sleeve 20 and generates pressure. This pressure is transmitted to the second circular pressure sensor 17 and the third circular pressure sensor 18, which convert the pressure signal into an electrical signal and transmit it to the external control mechanism. At the same time, during the pulling process, yarn 3 drives the upper guide sleeve 19 and the lower guide sleeve 20 to rotate, reducing the sliding friction between yarn 3 and the guide sleeves and reducing yarn 3 wear. The second circular pressure sensor 17 and the third circular pressure sensor 18 can monitor the pressure changes between the yarn 3 and the guide sleeve in real time, providing additional signal basis for the tension adjustment of the yarn 3.

[0070] The upper guide sleeve 19 and the lower guide sleeve 20 are connected by a movable sleeve, which allows the guide sleeve to rotate synchronously with the movement of the yarn 3, converting the sliding friction between the yarn 3 and the guide sleeve into rolling friction, greatly reducing the coefficient of friction, reducing the wear of the yarn 3, and extending the service life of the guide sleeve. The movable sleeve structure of the upper guide sleeve 19 and the lower guide sleeve 20 can act as a buffer when the yarn 3 experiences a momentary tension peak. When the tension of the yarn 3 suddenly increases, the guide sleeve can absorb part of the impact force through a slight rotation or displacement, preventing the tension peak from being directly transmitted to the fixed shaft and sensor, reducing the risk of component damage, and protecting the yarn 3 from breaking due to excessive momentary tension.

[0071] Based on any of the above technical solutions, a further optimization is made: the first circular pressure sensor 4, the second circular pressure sensor 17, and the third circular pressure sensor 18 are all connected to an externally configured pressure display and the existing control box signal.

[0072] In this solution, the first ring pressure sensor 4, the second ring pressure sensor 17, and the third ring pressure sensor 18 are connected by a signal connection method, which is existing technology. They transmit the pressure signals sensed by each sensor to an externally configured pressure display and an existing control box.

[0073] Signal connections can be wired (e.g., cable) or wireless to ensure the stability and timeliness of pressure signal transmission. After receiving the pressure signal, the pressure display shows the pressure data in a visual format (e.g., numbers, curves), allowing staff to monitor the pressure status of each sensor in real time.

[0074] The existing control box serves as the core of the equipment's control. Upon receiving a pressure signal, it analyzes and processes the signal according to preset control logic (such as pressure threshold and adjustment algorithm). If the pressure data exceeds the preset range, the control box sends control commands to the corresponding actuators (such as adjusting electric cylinder 8, lifting cylinder 13, translation cylinder group, and dual output shaft motor 5) to drive the actuators to move, thereby achieving automatic adjustment of the position of the rope presser, the position of the guide, etc., ensuring that the yarn 3 winding process is always in a stable state.

[0075] The pressure sensor converts physical pressure signals into electrical signals (such as analog signals 4-20mA or digital signals RS485), which are then transmitted to display and control devices via wired (cable) or wireless (Bluetooth, LoRa) methods. This signal conversion and transmission principle has been widely used in textile machinery, machine tools, chemical instruments, and other fields, and is common knowledge that can be grasped by those skilled in the art without creative effort. The externally configured pressure display is essentially a digital display instrument commonly used in the industrial field. The existing control box has a built-in PLC (Programmable Logic Controller) microcontroller, and mature supporting components can be directly purchased from the market, without the need for special design for the yarn winding equipment of this utility model.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
