Description

Technical Field

[0001] This invention belongs to the field of textile machinery technology, and in particular relates to a guide roller mechanism with tension self-compensation function. Background Technology

[0002] In the spinning, chemical fiber, and textile production processes, the guide roller mechanism is mainly used for guiding, pulling, and conveying the yarn. Its operational stability directly affects the yarn tension, drafting quality, and subsequent winding and forming effect. Existing guide roller mechanisms typically include a roller body, a support shaft, a mounting base, and a drive assembly. After the yarn passes around the roller surface, it is continuously conveyed under the action of the roller's rotation.

[0003] In actual production, factors such as yarn running speed, winding diameter, traction load, equipment start-up and shutdown, and the yarn's own elasticity can all cause tension variations. Tension fluctuations are particularly pronounced during high-speed continuous operation. Excessive tension can lead to overstretching, fraying, or even breakage of the yarn; insufficient tension can result in loose yarn, skipped strands, misalignment, or uneven winding, thus affecting product quality and production continuity.

[0004] In existing technologies, to control yarn tension, methods such as adjusting roller speed, installing tension sensors, adding rocker arm mechanisms, or manually adjusting the guide wire path are commonly used. However, most of these methods rely on external control or manual intervention, making the structural adjustment process relatively passive and difficult to compensate for instantaneous changes in tension.

[0005] The core defects of existing guide roller mechanisms are mainly as follows: First, rollers mostly adopt a fixed rigid installation structure. When the tension of the yarn suddenly increases or decreases, the roller itself cannot automatically generate buffer displacement or compensation action according to the tension change, resulting in tension fluctuations acting directly on the yarn, which can easily cause yarn breakage, loosening, or winding abnormalities. Second, the existing tension adjustment method has a lag in response. Especially in high-speed production processes, tension changes are instantaneous, and traditional electronic or manual adjustment cannot eliminate fluctuations in time, resulting in insufficient stability of yarn delivery.

[0006] To address this issue, we provide a guide roller mechanism with tension self-compensation function. Summary of the Invention

[0007] The purpose of this invention is to provide a guide roller mechanism with tension self-compensation function, which solves the problems of tension sudden changes, fluctuations and difficulty in adapting tension to different specifications of wire bundles during the winding process by combining mechanical negative feedback compensation with electromagnetic assisted adjustment.

[0008] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0009] This invention relates to a guide roller mechanism with tension self-compensation function, comprising:

[0010] The lower support frame has a lower support plate fixedly connected to its side surface. A compensation mechanism is provided on the upper side of the lower support plate. The compensation mechanism includes a damper, a first gear, a second gear, a third gear, an identification structure, and a feedback adjustment mechanism.

[0011] A locking mechanism is provided on the upper side of the lower support frame. The locking mechanism includes a first support rod, a power shaft, a second support rod, and an adjustment mechanism. The adjustment mechanism includes a non-power shaft, an electromagnet, and a gap. The non-power shaft is magnetically connected to the electromagnet. An electromagnetic adjuster is fixedly connected to the side surface of the second support rod.

[0012] The motor has a speed reducer fixedly connected to its output end.

[0013] The present invention is further configured such that a support foot is fixedly connected to the lower side of the lower support frame, a support plate is fixedly connected to the upper side of the compensation mechanism, and the support plate is fixedly connected to the damper.

[0014] The present invention is further configured such that the output end of the damper is fixedly connected to the first gear, and the second gear and the third gear are rotatably connected to the compensation mechanism, wherein the first gear meshes with the third gear, and the second gear meshes with the third gear.

[0015] The present invention is further configured such that the identification structure includes a response roller, a second support arm, a second connecting rod and a second partition plate, wherein the second support arm is fixedly connected to a second gear.

[0016] The invention is further configured such that the second support arm is rotatably connected to the response roller, the outer surface of the second connecting rod is fixedly connected to the second partition plate, and the upper side of the second partition plate is in contact with the response roller.

[0017] The present invention is further configured such that the feedback adjustment mechanism includes a negative feedback roller, a support shaft, an adjustment hole, a first partition plate, a first connecting rod, and a first support arm.

[0018] The present invention is further configured such that the third gear is fixedly connected to the first support arm, the adjustment hole is located on the side of the first support arm and distributed vertically, the support shaft passes through the adjustment hole, the outer side of the support shaft is rotatably connected to the negative feedback roller, the first support arm is fixedly connected to the first connecting rod, and the first connecting rod is fixedly connected to the first partition plate.

[0019] The present invention is further configured such that the adjusting mechanism includes an end cap and a first bolt, the first bolt is threadedly connected to the electromagnet, the end cap is fixedly connected to the power shaft, the electromagnetic adjuster is electrically connected to the electromagnet, and the second support rod and the first support rod are respectively fixedly connected to the lower support frame.

[0020] The invention is further configured such that a large support plate is fixedly connected to the upper side of the lower support frame by a second bolt, and the large support plate is provided with an opening for the movement of the non-powered shaft.

[0021] The invention is further configured such that the motor is fixedly connected to the large support plate, the output end of the reducer is fixedly connected to a rotating shaft, and a collecting roller is provided on the outer side of the rotating shaft.

[0022] The beneficial effects of this invention are as follows: This invention constructs a mechanical tension compensation chain consisting of a response roller, a second support arm, a second gear, a third gear, a first support arm, and a negative feedback roller. When the tension of the yarn bundle changes, the response roller displaces with the force of the yarn bundle, and drives the negative feedback roller to produce a corresponding compensation displacement via gear transmission, thus synchronously adjusting the yarn bundle conveying path and preventing excessive sag after tension release. The first gear, in conjunction with a damper, constrains the oscillation speed and stroke of the compensation mechanism, reducing the reciprocating oscillation of the response roller and the negative feedback roller, and maintaining a smooth tension change state of the yarn bundle during continuous conveying and winding. The support shaft can be installed in different adjustment holes on the first support arm to change the force arm and compensation stroke of the negative feedback roller, enabling the mechanism to adapt to the tension requirements of yarn bundles of different specifications.

[0023] This invention utilizes a power shaft, an electromagnet, and an electromagnetic regulator to form an electromagnetic-assisted adjustment structure. The electromagnetic regulator can adjust the magnetic attraction of the electromagnet to the power shaft, causing the position of the power shaft to change according to control requirements. This, in turn, alters the bending degree and conveying path length of the filament bundle at the power shaft, achieving further tension correction after mechanical compensation. The power shaft employs a lightweight rod with magnetically conductive parts, reducing the additional load on the filament bundle caused by its own weight while accepting electromagnetic effects. The first and second partition plates separate and guide the filament bundles passing through the compensation mechanism, reducing the crossing and entanglement of adjacent filament bundles during the oscillation compensation process. Combined with the continuous winding of the collecting roller, this ensures coordinated filament conveying, tension compensation, and winding processes. Attached Figure Description

The adjustment mechanism 24 includes a non-power shaft 28, an electromagnet 31 and a gap 29. The non-power shaft 28 and the electromagnet 31 are magnetically connected. An electromagnetic adjuster 25 is fixedly connected to the side surface of the second support rod 26.

[0037] Motor 34, and reducer 35 is fixedly connected to the output end of motor 34.

[0038] The lower side of the lower support frame 1 is fixedly connected to the support foot 2, and the upper side of the compensation mechanism 4 is fixedly connected to the support plate 5. The support plate 5 is fixedly connected to the damper 6.

[0039] The output end of the damper 6 is fixedly connected to the first gear 7, and the second gear 8 and the third gear 9 are rotatably connected to the compensation mechanism 4. The first gear 7 meshes with the third gear 9, and the second gear 8 meshes with the third gear 9.

[0040] The identification structure 15 includes a response roller 16, a second support arm 17, a second connecting rod 18 and a second partition plate 20, with the second support arm 17 fixedly connected to the second gear 8.

[0041] The second support arm 17 is rotatably connected to the response roller 16, the outer surface of the second connecting rod 18 is fixedly connected to the second partition plate 20, and the upper side of the second partition plate 20 is in contact with the response roller 16.

[0042] The feedback adjustment mechanism includes a negative feedback roller 11, a support shaft 12, an adjustment hole 13, a first partition plate 14, a first connecting rod 19, and a first support arm 10.

[0043] The third gear 9 is fixedly connected to the first support arm 10. The adjustment hole 13 is located on the side of the first support arm 10 and is distributed vertically. The support shaft 12 passes through the adjustment hole 13. The outer side of the support shaft 12 is rotatably connected to the negative feedback roller 11. The first support arm 10 is fixedly connected to the first connecting rod 19. The first connecting rod 19 is fixedly connected to the first partition plate 14.

[0044] The adjustment mechanism 24 also includes an end cap 27 and a first bolt 30, the first bolt 30 being threadedly connected to an electromagnet 31, the end cap 27 being fixedly connected to a power shaft 23, an electromagnetic adjuster 25 being electrically connected to an electromagnet 31, and a second support rod 26 and a first support rod 22 being fixedly connected to the lower support frame 1 respectively.

[0047] In summary, the compensation mechanism 4 forms a linked compensation structure through the response roller 16, the second support arm 17, the second gear 8, the third gear 9, the first support arm 10, and the negative feedback roller 11.

The first separator 14 and the second separator 20 separate and guide the filament bundle that has passed through the compensation mechanism 4. The motor 34 drives the collecting roller 36 to rotate via the reducer 35 and the rotating shaft 38, thereby completing the continuous conveying, tension compensation and winding collection of the filament bundle.

[0048] Example 2

[0049] Please see Figures 1-7 Based on Example 1, this example illustrates how the negative feedback roller 11 adapts to different specifications of filament bundles when the support shaft 12 is connected to different adjustment holes 13.

[0050] Based on the structure of Embodiment 1, the side of the first support arm 10 is provided with three adjustment holes 13 spaced apart in the vertical direction, namely the upper adjustment hole, the middle adjustment hole, and the lower adjustment hole. The support shaft 12 can selectively pass through one of the adjustment holes 13, and the negative feedback roller 11 is rotatably disposed on the outside of the support shaft 12.

[0051] With the connection center between the first support arm 10 and the third gear 9 as the rotation center, the distances between the upper adjustment hole, the middle adjustment hole, and the lower adjustment hole and the rotation center are 62mm, 52mm, and 42mm, respectively. Taking the 52mm lever arm length corresponding to the middle adjustment hole as the benchmark, the lever arm coefficients corresponding to the three adjustment holes 13 are 1.19, 1.00, and 0.81, respectively.

[0052] The correspondence between different filament specifications and the installation position of support shaft 12 is as follows:

[0053] Table 1: Installation Location Correspondence Table.

[0054] filament specifications Mounting position of support shaft 12 lever arm length Lever arm coefficient 50D / 24F Upper adjustment hole 13 62mm 1.19 150D / 48F Center position adjustment hole 13 52mm 1.00 300D / 96F Lower adjustment hole 13 42mm 0.81

[0055] When processing 50D / 24F filament bundles, the support shaft 12 is installed inside the upper adjustment hole 13. The force arm of the negative feedback roller 11 is 62mm. Under the condition that the output torque of the third gear 9 is the same, the pressure applied to the filament bundle by the negative feedback roller 11 is limited, which is suitable for fine filament bundles.

[0056] When processing 150D / 48F filament bundles, the support shaft 12 is installed in the center adjustment hole 13 with a lever arm length of 52mm, serving as the reference connection position for the compensation mechanism 4. After the response roller 16 is displaced, the second gear 8 drives the third gear 9 to rotate, and the third gear 9 drives the negative feedback roller 11 via the first support arm 10 to compensate for the filament bundle.

[0057] When processing 300D / 96F filament bundles, the support shaft 12 is installed in the lower adjustment hole 13. The force arm of the negative feedback roller 11 is 42mm. Under the condition that the output torque of the third gear 9 is the same, the negative feedback roller 11 can apply the corresponding compensation pressure to the filament bundle, which is suitable for coarse filament bundles.

[0058] When changing the yarn bundle specification, stop the motor 34 and the collecting roller 36, remove the support shaft 12 from the original adjustment hole 13, and install it into the adjustment hole 13 corresponding to the target yarn bundle specification. By changing the connection position between the support shaft 12 and the adjustment hole 13, the force arm and compensation pressure of the negative feedback roller 11 can be adjusted, so that the compensation mechanism 4 can adapt to the tension compensation requirements of yarn bundles of different specifications.

[0059] The working principle of this invention is as follows: the filament bundle passes sequentially from the upper side of the response roller 16, the lower side of the negative feedback roller 11, the lower side of the power shaft 23, and the upper side of the collecting roller 36, and then winds around the outer periphery of the collecting roller 36. The power output from the motor 34 is transmitted to the rotating shaft 38 via the reducer 35. The rotating shaft 38 drives the collecting roller 36 to rotate, so that the filament bundle is continuously conveyed along a predetermined path and the winding is completed.

[0060] The compensation mechanism 4 includes an identification structure 15 and a feedback adjustment mechanism. The filament bundle passes over the upper side of the response roller 16 of the identification structure 15, and the response roller 16 bears the force generated by the tension of the filament bundle. When the tension of the filament bundle increases, the filament bundle exerts a downward pressure on the response roller 16, causing the response roller 16 to swing downward with the second support arm 17. After the response roller 16 moves downward, the degree of bending of the filament bundle at the response roller 16 is reduced, and the filament bundle transport path is shortened accordingly, thereby releasing part of the tension.

[0061] The second support arm 17 is connected to the second gear 8. When the response roller 16 swings downward, the second support arm 17 drives the second gear 8 to rotate. The second gear 8 meshes with the third gear 9. After the second gear 8 rotates, it drives the third gear 9 to rotate in the opposite direction. The third gear 9 is connected to the first support arm 10. When the third gear 9 rotates, it drives the first support arm 10 and the negative feedback roller 11 to swing downward. Since the filament bundle passes under the negative feedback roller 11, the downward movement of the negative feedback roller 11 increases the degree of bending of the filament bundle at the corresponding position and extends the conveying path of the filament bundle, so that the filament bundle maintains the corresponding tension and avoids excessive drop in filament bundle tension after the response roller 16 moves downward.

[0062] The response roller 16 and the negative feedback roller 11 are linked by the second gear 8 and the third gear 9. The response roller 16 generates a tension release displacement according to the change in yarn tension, and the negative feedback roller 11 synchronously generates a compensating displacement, thus constraining the tension release process and forming a mechanical negative feedback adjustment. After the yarn tension returns, the response roller 16, the second support arm 17, the second gear 8, the third gear 9, the first support arm 10, and the negative feedback roller 11 rotate back to their initial positions under the combined action of the yarn force and the mechanism's restoring force.

[0063] The first gear 7 meshes with the third gear 9, and the first gear 7 is connected to the working end of the damper 6. When the third gear 9 rotates, it drives the first gear 7 to rotate. The damper 6 applies a damping effect to the rotation of the third gear 9 through the first gear 7, limiting the swing speed and swing stroke of the second support arm 17 and the first support arm 10, suppressing the reciprocating oscillation of the response roller 16 and the negative feedback roller 11 when the tension changes continuously, so that the compensation mechanism 4 completes the tension compensation at a controlled speed.

[0064] The first support arm 10 is provided with adjustment holes 13 spaced apart in the vertical direction. The support shaft 12 can be selectively installed in one of the adjustment holes 13, and the negative feedback roller 11 is rotatably mounted on the support shaft 12. By adjusting the installation position of the support shaft 12 in different adjustment holes 13, the distance between the rotation center of the negative feedback roller 11 and the first support arm 10 can be changed, thereby changing the force arm, swing stroke, and compensating force applied to the filament bundle by the negative feedback roller 11, so that the compensation mechanism 4 can adapt to the tension adjustment requirements of filament bundles of different specifications.

[0065] When the filament bundle passes through the compensation mechanism 4, it passes along the guide interval formed by adjacent first partition plates 14. The first partition plate 14 is connected to the first connecting rod 19 and moves synchronously with the first support arm 10. A second partition plate 20 is provided on one side of the identification structure 15, and adjacent second partition plates 20 separate the filament bundles passing through the response roller 16. The first partition plate 14 and the second partition plate 20 together restrict the lateral movement of adjacent filament bundles, so that each filament bundle remains separated from each other during the tension compensation process, reducing filament bundle crossing and entanglement.

[0066] The drive shaft 23 is a lightweight rod with a magnetically conductive part. The wire bundle passes under the drive shaft 23 and provides upward support to the drive shaft 23. The lightweight structure of the drive shaft 23 can limit the additional influence of its own weight on the tension of the wire bundle; the magnetically conductive part of the drive shaft 23 allows it to accept the magnetic attraction generated by the electromagnet 31.

[0067] The electromagnetic regulator 25 is electrically connected to the electromagnet 31 and is used to adjust the energization state and magnetic attraction force of the electromagnet 31. The electromagnet 31 applies a magnetic attraction to the magnetically conductive parts linked to the drive shaft 23, causing the drive shaft 23 to produce controlled displacement under the constraint of the adjustment mechanism 24. The change in position of the drive shaft 23 can change the degree of bending of the wire bundle at the drive shaft 23 and the length of the conveying path, thereby actively adjusting the wire bundle tension.

[0068] When the tension of the filament bundle increases, the electromagnetic regulator 25 controls the electromagnet 31 to change the magnetic attraction force, causing the drive shaft 23 to move in the direction that reduces the bending degree of the filament bundle, thus shortening the conveying path of the filament bundle at the drive shaft 23. When the tension of the filament bundle decreases, the electromagnetic regulator 25 controls the drive shaft 23 to move in the direction that increases the bending degree of the filament bundle, thus lengthening the conveying path of the filament bundle. The drive shaft 23 relies on electromagnetic action for position adjustment, and no rigid pushing component is needed to directly impact the filament bundle during the adjustment process.

[0069] The compensation mechanism 4 provides mechanical follow-up compensation for changes in yarn tension, while the electromagnetic regulator 25, electromagnet 31, and drive shaft 23 actively correct the yarn tension. When the two parts work together, the response roller 16 first generates displacement according to the changes in yarn tension, the negative feedback roller 11 forms reverse compensation through gear transmission, the damper 6 limits the oscillation state of the compensation mechanism 4, and the drive shaft 23 changes the yarn conveying path according to the tension control requirements. This achieves continuous adjustment of yarn tension and limits sudden tension changes during winding.

[0070] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
