Description

Technical Field

[0001] This invention relates to the field of polyester filament winding technology, specifically to an intelligent tension control winding device for differentiated polyester filaments. Background Technology

[0002] Differentiated polyester filament is a chemical fiber material made by modifying the cross-sectional structure, crimp, and physical properties of ordinary polyester fibers through a modification process. It possesses advantages such as a soft hand feel, excellent breathability, and uniform dyeing, and is widely used in home textiles, apparel weaving, and industrial fabrics. In the production process of differentiated polyester filament, the winding equipment is the core production equipment for subsequent forming and processing. Its main function is to orderly wind the stretched and shaped polyester filaments in a spiral interlaced arrangement, forming a regular cylindrical filament roll, which facilitates the storage, transportation, and subsequent secondary processing of the finished chemical fiber product. In the secondary weaving process, the polyester filament winding equipment currently used in the chemical fiber production industry generally adopts a winding process of guide yarn lateral movement combined with roller rotation. The equipment is conventionally equipped with basic tension control components. Most of the mainstream tension control methods on the market are designed to compensate for the tension changes that occur during the increase of the radial diameter of the yarn roll. Traditional tension control structures mostly use passive pressure stabilization methods such as pressure rollers and spring damping. The structure is simple and the maintenance cost is low. It can meet the basic winding production requirements of ordinary polyester filament and is currently the most universal and technologically mature supporting production structure in the chemical fiber textile field.

[0003] Given the unique material properties of polyester yarn—soft texture and high tension sensitivity—existing traditional winding equipment suffers from a single and prominent structural technical deficiency. It struggles to adapt to the dynamic tension fluctuations generated during the transverse reciprocating winding process. In conventional spiral winding operations, the yarn undergoes a regular transverse reciprocating oscillation with the guide components. The length of the yarn suspended in the air changes continuously with the oscillation position. When the yarn oscillates to both ends of the roll, the yarn is passively stretched, and the overall tension increases synchronously. When the yarn oscillates to the middle of the roll, the yarn loosens, and the tension decreases accordingly. Existing traditional winding equipment can only compensate for the increase in radial diameter of the yarn roll. The tension deviation, without a dedicated compensation mechanism for tension fluctuations caused by the difference in lateral swing stroke, directly results in tightly wound ends and loosely wound middle sections of the finished yarn roll, leading to poor overall density uniformity. This not only affects the neatness of the finished product's appearance but also makes it prone to processing defects such as yarn stripping, jamming, and yarn breakage during subsequent unwinding, directly reducing the finished product's pass rate. This cannot be improved by conventional production methods such as manual fine-tuning and speed adjustment, severely restricting the large-scale and stable production and processing of high-quality differentiated polyester yarn. Therefore, we propose an intelligent tension control winding device for differentiated polyester yarn. Summary of the Invention

[0011] Preferably, the side wall of the tension frame is provided with four horizontally distributed conveying rods, which are perpendicular to the side wall of the tension frame. The four conveying rods are symmetrically distributed on both sides of the top of the side plate frame, and the shaft end of the conveying rod is provided with an auxiliary pulley, which is in rolling cooperation with the polyester yarn.

[0012] Preferably, the inner wall of the side plate frame is provided with three first sliding grooves, the first sliding grooves have an isosceles trapezoidal structure in radial cross section, the three first sliding grooves are distributed in a T-shape, and the three first sliding grooves are located on the side of the guide rod.

[0013] Preferably, the slide cylinder is slidably engaged with the guide rod inside, and a connecting block is provided on one side shaft end of the slide cylinder.

The sliding columns are slidably engaged with the interior of the second sliding groove. The side wall of the slide cylinder is provided with four symmetrically distributed third sliding grooves, which are slidably engaged with the guide plate. The side shaft end of the slide cylinder away from the connecting block is provided with four symmetrically distributed connecting seats.

[0014] Preferably, the sidewall of the sliding sleeve is provided with three first connecting seats arranged in a T-shape, and a sliding hole is opened in the center of the sliding sleeve. The sliding hole is concentric with the third sliding groove. The sliding hole slides with the guide rod. The sliding sleeve is detachably connected to the connecting seat along the axial end sidewall of the sliding hole by an adapter screw.

[0015] Preferably, the slider consists of three parts: a connecting column, a second connecting seat, and a slider. The connecting column is a cylindrical rod structure and rotates with the conveying pulley. The second connecting seat and the slider are located at the two ends of the connecting column, and the slider is perpendicular to the connecting column. The slider has an isosceles trapezoidal cross section and slides with the first groove.

[0016] Preferably, the connecting rod is a rectangular rod structure, and both ends of the connecting rod are provided with connecting holes, which are rotatably connected to the first connecting seat and the second connecting seat, respectively.

[0018] Compared with the prior art, the present invention provides an intelligent tension control winding device for differentiated polyester yarns, which has the following advantages:

[0019] This intelligent tension control winding device for differentiated polyester yarns adds a tension adjustment component consisting of a drive unit and an adjustment unit to the existing radial tension adjustment structure of the winding machine. This effectively improves the winding quality of differentiated polyester yarns and is suitable for continuous industrial production. It relies on a first motor to drive a cam to rotate, which in turn drives the slide drum, slide sleeve, and connecting rod to complete the mechanical transmission. This drives the slider to slide inside the first groove, changing the relative position of the conveyor pulleys and adjusting the polyester yarn's travel distance in real time. The cam rotation phase matches the reciprocating travel of the yarn guide, thus controlling the yarn guide's movement. When the yarn tension increases near both ends of the take-up drum, the polyester yarn travel stroke is actively reduced to counteract the tensile tension. When the guide is in the middle position and the yarn tension is low, the travel stroke is increased to maintain the yarn tension. This structure can synchronously adapt to the guide oscillation rhythm and dynamically balance the tension fluctuations caused by the lateral travel difference, ensuring that the tightness of the polyester yarn winding is consistent throughout the axial direction of the take-up drum. This reduces yarn wear and equipment jamming, eliminates the need for repeated manual parameter adjustments, adapts to the characteristics of different polyester yarn materials, improves the uniformity of yarn drum forming, optimizes finished product quality, and reduces the defect rate in later use.

[0032] 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.

[0033] Please see Figure 1-11 The present invention provides a technical solution;

[0034] A smart tension control winding device for differentiated polyester yarn includes a polyester yarn 9, a tension control end and a winding end, wherein the winding end is located at the tail of the tension control end, and the polyester yarn 9 passes through the tension control end and is wound by the winding end.

[0035] The tension control end consists of a tension frame 1 and a tension adjustment assembly. The tension frame 1 has a side plate frame 4 on its side wall. The side plate frame 4 is a horizontally placed rectangular structure. The tension adjustment assembly consists of a drive part and an adjustment part. The drive part is located inside the tension frame 1, and the adjustment part is located inside the side plate frame 4.

[0036] The drive unit consists of a first motor 10 and a cam 11. The rotation output shaft of the first motor 10 is connected to the cam 11 through a coupling. The outer sides of the two opposite sidewalls of the cam 11 are provided with second sliding grooves 22.

[0037] The adjustment unit consists of a slide cylinder 12, a slide sleeve 18, a connecting rod 19, a slider 20, and a conveying pulley 21. One side of the slide cylinder 12 is slidably engaged with the inside of the side wall of the cam 11. The other side of the slide cylinder 12 is provided with a slide sleeve 18. The side wall of the slide sleeve 18 is provided with three connecting rods 19 distributed at ninety degrees. The three connecting rods 19 are inclined and have rotational freedom. The connecting rod 19 is provided with a slider 20 at its shaft end. The slider 20 is rotatably engaged with the shaft end of the connecting rod 19, and the slider 20 is slidably engaged with the inner wall of the side plate frame 4. The conveying pulley 21 is located outside the slider 20 and has rotational freedom.

[0038] Furthermore, the side wall of the tension frame 1 is a horizontally placed rectangular plate structure. A control box 3 is located at the back of the tension frame 1, and a telescopic opening 13 is provided at the center of the side wall. The telescopic opening 13 is a square frame structure and corresponds to the inner wall of the side plate frame 4. An installation plate 17 is located inside the tension frame 1, situated beside the telescopic opening 13. The installation plate 17 is detachably connected to the first motor 10 via adapter bolts. The tension frame 1 adopts a one-piece plate-type molding structure, possessing high bending strength and capable of withstanding reciprocating mechanical vibrations for extended periods without deformation. The back is integrated with... The control box 3 is the intelligent control center of the whole machine. It integrates logic control program and can collect signals such as the speed of the second motor 32, the displacement position of the wire guide 7, and the rotation phase of the cam 11 to realize the timing matching of multi-motor linkage. The telescopic port 13 of the square frame limits the outer perimeter of the slide cylinder 12 to prevent radial rotation. The mounting plate 17 on the side facilitates the daily inspection, disassembly, lubrication and maintenance of the first motor 10. It can also manually fine-tune the motor installation position, accurately calibrate the coaxiality of the motor shaft and the cam shaft, reduce transmission error and ensure the stability of tension adjustment.

[0039] Furthermore, a guide rod 14 is provided at the center of the telescopic opening 13, and four symmetrically distributed guide plates 15 are provided on the side wall of the guide rod 14. The guide plates 15 are rectangular plates, and the guide plates 15 are welded to the internal corners of the telescopic opening 13 along the long axis. The axial end of the telescopic opening 13 opposite to the guide plates 15 is welded to the inner wall of the side plate frame 4. The guide rod 14 provides a central sliding reference for the slide cylinder 12, constraining the slide cylinder 12 to only move in a straight line along the axial direction to prevent offset and swaying. The four symmetrically welded guide plates 15 constitute a four-way limiting guide. The guide structure, together with the guide rod 14, forms a double guide, and the welding and fixing method makes the guide plate 15, telescopic port 13, and side plate frame 4 form an integrated rigid frame. Under long-term high-frequency reciprocating motion, there will be no loosening or displacement, and the structure has extremely strong stability. This double guide structure can completely offset the lateral component force of the cam 11, avoid problems such as radial deflection, jamming, and accelerated wear of the slide cylinder 12, ensure the smooth sliding of the slide cylinder 12, reduce mechanical noise and friction loss, extend the service life of the equipment, and is suitable for long-term continuous uninterrupted production conditions in the chemical fiber industry.

[0040] Furthermore, the side wall of the tension frame 1 is provided with four horizontally distributed conveying rods 5, which are perpendicular to the side wall of the tension frame 1. The four conveying rods 5 are symmetrically distributed on both sides of the top of the side plate frame 4, and the shaft end of the conveying rod 5 is provided with an auxiliary pulley. The auxiliary pulley rolls in cooperation with the polyester filament 9. The four conveying rods 5 are arranged symmetrically from left to right to form a smooth, horizontal, and regular front-feeding channel, avoiding excessive tension loss caused by excessive inclination angle. The auxiliary pulleys at the rod ends adopt a low-friction rolling structure to replace the traditional rigid guide ring, which greatly reduces the surface friction scratches during the conveying process of polyester filament 9. It is suitable for the material characteristics of differentiated polyester filaments that are thin, easy to fray, and easy to damage. At the same time, multiple sets of auxiliary pulleys can limit the left and right movement of the filament and prevent deviation correction, ensuring that the polyester filament 9 enters the internal adjustment area of ​​the side plate frame 4 accurately, smoothly, and without deviation, providing stable feeding conditions for subsequent high-precision tension adjustment.

[0041] Furthermore, the inner wall of the side plate frame 4 is provided with three first sliding grooves 16. The radial cross-section of the first sliding groove 16 is an isosceles trapezoidal structure, and the three first sliding grooves 16 are distributed in a T-shape. The three first sliding grooves 16 are located on the side of the guide rod 14. The three first sliding grooves 16 are arranged in a T-shaped spatial arrangement to precisely match the linkage swing trajectory of the three connecting rods 19, ensuring that the movement trajectory of each group of sliders 20 does not interfere with each other, and realizing the synchronous and equal amplitude displacement of the three conveying pulleys 21. The isosceles trapezoidal cross-section is an anti-detachment sliding groove structure with a narrow groove opening and a wide groove bottom, which can firmly lock the slider 20's slider strip 31, preventing the slider from jumping out, deviating, or jamming during high-speed sliding. The three first sliding grooves 16 are concentrated on the side of the guide rod 14, shortening the power transmission stroke, reducing transmission energy loss, and improving the tension response speed. The three first sliding grooves 16 are independently limited and move in coordination, so that the polyester yarn 9 is supported and adjusted uniformly, multi-point, and synchronously, further improving the tension balance effect.

[0042] Furthermore, the slide cylinder 12 is slidably fitted with the guide rod 14. A connecting block 23 is provided on one side of the shaft end of the slide cylinder 12. The connecting block 23 has a U-shaped block structure, and two opposite inner walls of the connecting block 23 are provided with sliding columns 24. The sliding columns 24 are slidably fitted with the second sliding groove 22. Four symmetrically distributed third sliding grooves 26 are opened on the side wall of the slide cylinder 12. The third sliding grooves 26 are slidably fitted with the guide plate 15. Four symmetrically distributed connecting seats 25 are provided on the shaft end of the slide cylinder 12 away from the connecting block 23. The U-shaped connecting block 23 is semi-enclosed and fitted. The outer wall of the cam 11 is adapted to the changing pattern of the cam profile. Two sliding pillars 24 are embedded in the double-sided second sliding grooves 22 to form a double-point sliding hinge structure. The transmission has no idle stroke and no lag. It can accurately capture the position changes of the far end and near end of the cam and smoothly convert the rotational motion into linear thrust. The four sets of symmetrically arranged third sliding grooves 26 correspond one-to-one with the guide plate 15 to achieve four-way synchronous limiting, further correct the sliding posture of the slide cylinder 12, and eliminate eccentric wear. The evenly arranged connecting seats 25 at the tail are detachable connection points, so that the slide cylinder 12 and the slide sleeve 18 are assembled compactly.

[0043] Furthermore, the side wall of the sliding sleeve 18 is provided with three first connecting seats 27 arranged in a T-shape, and the center of the sliding sleeve 18 is provided with a sliding hole 28. The sliding hole 28 is concentric with the third sliding groove 26. The sliding hole 28 is slidably engaged with the guide rod 14. The sliding sleeve 18 is detachably connected to the connecting seat 25 along the axial end side wall of the sliding hole 28 by an adapter screw. The sliding hole 28 and the guide rod 14 are arranged concentrically to ensure that the sliding axis of the sliding sleeve 18 is consistent. The clearance fit reduces the sliding friction coefficient, reduces movement jamming and heat loss. The T-shaped first connecting seats 27 are precisely aligned with the installation points of the three connecting rods 19 to achieve uniform load distribution and avoid stress concentration at a single point causing deformation of the connecting parts. The screw detachable connection structure not only facilitates disassembly, maintenance, cleaning and lubrication, but also allows for fine adjustment of the installation gap during assembly to adapt to different precision production requirements. The sliding sleeve 18 moves axially synchronously with the sliding cylinder 12. As an intermediate transmission hub, it stably and evenly transmits power to the three sets of linkage mechanisms to ensure the consistency of multi-channel tension adjustment actions.

[0044] Furthermore, the slider 20 consists of three parts: a connecting column 29, a second connecting seat 30, and a slider 31. The connecting column 29 is a cylindrical rod structure, and it rotates with the conveying pulley 21. The second connecting seat 30 and the slider 31 are located at the two ends of the connecting column 29, and the slider 31 is perpendicular to the connecting column 29. The slider 31 has an isosceles trapezoidal cross-section and slides with the first slide groove 16. The second connecting seat 30 serves as the power input end, receiving the connecting rod 1. The push-pull or power of 9, the vertically arranged isosceles trapezoidal slide bar 31 is adapted to the anti-detachment structure of the slide groove, with strong sliding stability and high wear resistance. The cylindrical connecting column 29 provides a rotation fulcrum for the conveying pulley 21, ensuring that the pulley rotates flexibly and guides the yarn smoothly. The spatial structure of the three vertically distributed components reasonably disperses mechanical stress, avoiding breakage and deformation due to long-term reciprocating motion. It allows the conveying pulley 21 to be precisely and finely adjusted with the slider 20, changing the wrap angle of the polyester yarn 9 in real time, and accurately compensating for the stroke tension difference caused by the swing of the yarn guide 7.

[0045] Furthermore, the connecting rod 19 is a rectangular rod structure, and both ends of the connecting rod 19 are provided with connecting holes. The two connecting holes are respectively rotatably connected to the first connecting seat 27 and the second connecting seat 30. The connecting holes at both ends form a hinged rotating pair, which enables the connecting rod 19 to have bidirectional adaptive deflection capability. It can adapt to the angular offset caused by the axial movement of the sliding sleeve 18 and the radial movement of the slider 20 in real time, eliminate mechanical motion dead points and transmission interference. The hinged structure has low frictional resistance and sensitive transmission, and can transmit displacement without delay, ensuring that the tension adjustment action and the swing action of the wire guide 7 are strictly synchronized, and realizing dynamic real-time compensation.

[0046] Furthermore, the bottom of the winding end is a winding frame 2, and the top of the winding frame 2 is equipped with a lead screw 6. A wire guide 7 is located on the outside of the lead screw 6, and the wire guide 7 has a sliding degree of freedom along the axial direction of the lead screw 6. A second motor 32 is located at the bottom of one side of the shaft end of the lead screw 6. The output of the second motor 32 is connected to the shaft end of the lead screw 6 via a belt, and the lead screw 6 is located near the tension frame 1. The top of the winding frame 2 is equipped with a winding drum 8, and the bottom of one side of the shaft end of the winding drum 8 is equipped with a third motor 33. The output shaft of the third motor 33 is connected to the shaft end of the winding drum 8 via a belt. The winding frame 2 is a high-strength load-bearing frame, ensuring structural stability when the lead screw 6 and winding drum 8 are operating, and suppressing high-speed winding. Resonance and belt drive have the advantages of buffering and shock absorption, overload slippage protection, noise reduction and wear resistance. They can avoid the polyester yarn 9 from breaking due to excessive instantaneous tension in rigid transmission. The second motor 32 drives the lead screw 6 to rotate. Relying on the lead screw spiral transmission principle, it drives the guide 7 to make uniform reciprocating linear motion, realizing the spiral cross winding of the polyester yarn 9. The third motor 33 independently drives the take-up drum 8 to rotate at a constant speed. It matches the guide speed to control the winding density. The lead screw 6 is arranged close to the tension frame 1 to shorten the distance of the yarn suspended in the air and reduce the tension interference caused by air vibration. The timing of the winding action, the guide action and the tension adjustment action are highly matched to form a complete closed loop winding.

[0047] Working principle: Install the intelligent tension control winding device for differentiated polyester yarns correctly according to the diagram. This device is located at the rear end of the winding machine. After the polyester yarn 9 passes through the inside of the winding machine, it passes through the conveyor rod 5 and enters the side plate frame 4 in its middle section, that is, outside the adjustment part of the tension adjustment component. Then it is conveyed by the conveyor rod 5 to the inside of the take-up guide 7. After passing through the inside of the guide 7, it will be wound around the outside of the take-up drum 8. The guide 7 will be driven by the forward and reverse rotation of the second motor 32 to drive the screw 6 to rotate forward and reverse synchronously. Thus, the guide 7 is reciprocated and slids, and the polyester yarn 9 is reciprocated and spirally wound around the outside of 8.

[0048] During the reciprocating sliding process of the guide wire 7, the polyester filament 9 will swing in an isosceles triangle shape with the conveyor rod 5 at the very end and the inlet section of the guide wire 7. That is, when the guide wire 7 is in the middle position, the tension of the polyester filament 9 is in a normal state. When the guide wire 7 is in the extreme positions on both sides, the polyester filament 9 will stretch, that is, the tension will increase. At this time, the winding ends of the take-up drum 8 are relatively tight, while the middle is relatively loose. The tension adjustment component can solve this problem, specifically:

[0049] The first motor 10 of the drive unit drives the cam 11 to rotate through the coupling. During the rotation, the second slide groove 22 on the outer side of the cam 11 drives the slide cylinder 12 of the adjustment unit to slide back and forth. The slide cylinder 12 slides axially along the guide rod 14. During the sliding of the slide cylinder 12, the sliding cooperation between the third slide groove 26 and the guide plate 15 effectively ensures the smoothness of its axial sliding and prevents it from radially deflecting. During the axial sliding of the slide cylinder 12, the slide sleeve 18 slides synchronously. The sliding of the slide sleeve 18 drives the three connecting rods 19 to rotate. The connecting rods 19 synchronously pull or push the three sliders 20 to slide inside the first slide groove 16, thereby changing the path of the polyester yarn 9 that passes around the outside of the three conveying pulleys 21.

[0050] When the guide 7 is in the middle section of the take-up drum 8, the far end of the cam 11 corresponds to the connecting block 23 of the slide drum 12. At this time, the adjustment part is in the maximum stroke state, and the stroke formed by the three second slide grooves 22 is at its maximum, which is the normal tension state. When the guide 7 is in the extreme position on one side of the take-up drum 8, the near end of the cam 11 corresponds to the connecting block 23, and the adjustment part is in the initial state. At this time, the stroke formed by the three second slide grooves 22 is at its minimum. That is, the stroke change of the second slide grooves 22 is exactly the tension stretching change when the guide 7 is in the extreme position. The single stroke of the guide 7 corresponds to two turns of the cam 11, thereby achieving consistent pressure at both ends and in the middle of the polyester yarn 9 spirally wound on the outside of the take-up drum 8 by the guide 7.

[0052] The first motor 10, the second motor 32, and the third motor 33 all adopt small AC servo motors commonly used in existing textile and chemical fiber equipment. They have built-in encoders to achieve high-precision speed feedback, support stepless speed regulation and frequent switching between forward and reverse rotation, with a speed error of ≤±0.5%. The protection level reaches IP54, which is dustproof, anti-flying material, and anti-oil mist. They are suitable for the harsh working conditions in polyester spinning workshops. The motors have built-in electromagnetic brakes that lock the shaft instantly when the machine stops to prevent the yarn from springing back and loosening. They are widely used in chemical fiber equipment such as texturing machines, winding machines, and yarn guides.

It has the ability to reduce vibration, noise, and compensate for axial, radial and angular installation deviations. It is maintenance-free, wear-resistant and has high transmission efficiency. It is suitable for low-speed, high-torque precision transmission and is widely used in spinning cams and small shaft precision connection scenarios.
