Description

Technical Field

[0001] The present invention relates to fiber winding, and more specifically, to a fully automatic fiber winding device based on winding tension control. Background Technology

[0002] Fully automatic fiber winding equipment is widely used in the winding and forming of high-performance fiber materials such as carbon fiber, glass fiber, and aramid fiber, covering multiple industries such as aerospace, wind power, automotive lightweighting, and textile fiber. Its core function is to wind continuous fiber bundles uniformly and densely onto a mandrel or roll according to a preset pattern to form fiber rolls that meet specific strength and precision requirements. It is one of the key equipment for the preparation of fiber composite materials and textile processing.

[0003] For example, Chinese patent application No. 202311461130.0 discloses a carbon fiber rewinding mechanism and its rewinding method, including a mounting panel, a turntable, two stop bars, two winding mechanisms, and a cutting mechanism; the winding mechanism includes a winding assembly and a clamping assembly sleeved on the winding assembly. The clamping assembly includes a first clamping plate, a telescopic moving assembly, a second clamping plate, and several limiting mechanisms connected to the second clamping plate. The limiting mechanisms are used to limit the distance that the filament bundle moves toward the circular edge of the clamping assembly when it is under tension. In this invention, a limiting mechanism is added to the moving second clamping plate. After the filament bundle falls between the first clamping plate and the second clamping plate, it will be blocked by the limiting mechanism, which can effectively prevent the filament bundle from being pulled out between the first clamping plate and the second clamping plate, and is not limited by speed and cutting force.

[0004] Although the above invention achieves the limiting and constraint of the fiber bundle through the first clamping plate, the second clamping plate and the matching limiting mechanism, its fixing method of the fiber bundle is still limited to mechanical clamping and positioning. At the moment when the cutting tool performs the cutting action on the fiber bundle, the tension of the bundle will undergo a violent instantaneous change. Relying solely on the frictional force formed by the clamping force is difficult to achieve reliable anchoring during the cutting of the bundle and the tension change process. Once the tension fluctuation exceeds the preset threshold, the clamping frictional force cannot provide sufficient locking force to constrain the fiber bundle, which can easily lead to failures such as fiber bundle unanchoring and displacement during automatic roll changing, resulting in the failure of the roll changing action. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fully automatic fiber winding device based on winding tension control to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic fiber winding device based on winding tension control, comprising a main body, the main body including a conversion unit, a drive unit, a cutter, and a wire guide, and further comprising: The guiding mechanism includes a take-up shaft with a guiding component on it and a tension control wheel on the main body. When the cutting blade cuts the fiber, the instantaneous change in tension drives the tension control wheel to swing, so that the guiding component fixes the free end of the fiber to the take-up shaft. The adjustment mechanism includes a tension adjustment component, which can pre-adjust the swing angle of the tension control wheel by predicting the change in tension when the cable reversing.

[0007] Preferably, the guiding component includes a fixing block fixedly connected to the take-up shaft, and a plurality of clamping blocks are slidably connected to the rear end of the take-up shaft via splines. The fixing block and the clamping blocks are provided with slots, and the slots on the fixing block are provided with anti-reverse parts.

[0008] Preferably, a rotating shaft is rotatably connected to the main body via a torsion spring, a control rod is fixedly connected to the front end of the rotating shaft, the end of the control rod is inserted into the main body and hinged to a connecting rod, and a vertical block is hinged to the free end of the connecting rod.

[0009] Preferably, the vertical block is slidably connected to the main body, the upper end of the vertical block is provided with a contact block, a push plate is slidably connected inside the main body, an elastic element is provided between the push plate and the main body, the push plate corresponds to the clamping block, and when the contact block moves upward to the push plate, it can push the clamping block to move toward the fixed block.

[0010] Preferably, the tension adjustment assembly includes a synchronization block that is synchronously arranged with the cable guide. The synchronization block is connected to the cable guide via a synchronization rod. A telescopic rod is fixedly connected to the lower end of the synchronization block. The main body is provided with a positioning block located below the synchronization block. A sliding groove is provided on the positioning block, and the telescopic rod is slidably connected to the sliding groove.

[0011] Preferably, an electric actuator is fixedly connected below the positioning block, and an adjusting block is fixedly connected to the free end of the electric actuator, the adjusting block being able to contact the contact block.

[0012] Preferably, there are two contact blocks distributed in a front-to-back direction, and the positions of the contact blocks correspond to the extreme positions of the cable tray's back-to-back reciprocating movement.

[0013] Preferably, the conversion unit includes a turntable with a stop bar on it, and the cutting blade is located between the stop bar and the winding wheel.

[0014] Preferably, the conversion unit includes a conversion block, on which a ball screw is rotatably connected, and the ball screw drives the cable guide to reciprocate.

[0015] Preferably, the main body is provided with a control module, which is capable of controlling the operation of the drive unit.

[0016] The technical effects and advantages of this invention are as follows: 1. This invention utilizes the coordinated arrangement of a tension control wheel, control rod, connecting rod, vertical block, contact block, push plate, and guide assembly. It takes advantage of the instantaneous tension change at the moment of fiber cutting as a power source to drive the tension control wheel to swing and link the guide assembly to move. Through the wrapping constraint of the V-shaped groove and the anti-detachment limit of the anti-retardation part, combined with the squeezing and locking of the clamping block, the free end of the fiber is mechanically anchored to the take-up shaft. This effectively avoids fiber detachment and displacement caused by tension fluctuations, completely solving the core problem of roll changing failure in existing technologies. Moreover, it does not require an additional power source, simplifying the structure and reducing energy consumption.

[0017] 2. This invention, through the coordinated arrangement of a synchronization block, positioning block, electric actuator, adjusting block, and tension control wheel, pre-controls tension fluctuations during the reversal of the yarn guide, ensuring fiber and package quality. Addressing the issue of tension fluctuations during the "deceleration-stop-reverse acceleration" process of the yarn guide, a predictive control mechanism is implemented. The synchronization block, moving synchronously with the yarn guide, drives the adjusting component. When the yarn guide reaches its reversal limit position, the adjusting block pre-adjusts the swing angle of the tension control wheel, tightening or buffering fiber tension in advance. This significantly reduces tension peak and trough fluctuations during reversal, preventing brittle fiber breakage and elastic fiber fatigue damage, as well as defects such as uneven end faces, uneven yarn spacing, and interlayer slippage in the package, ensuring consistent package density and compatibility with subsequent processing.

[0026] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example 1

[0027] In existing technologies, the fiber bundle is constrained by a clamping and limiting mechanism. However, the method of fixing the fiber bundle is still limited to mechanical clamping and positioning. At the moment when the cutting blade 14 performs the cutting action on the fiber bundle, the tension of the bundle will undergo a violent instantaneous change. Relying solely on the frictional force generated by the clamping force is not enough to achieve reliable anchoring during the cutting and tension change process. Once the tension fluctuation exceeds the preset threshold, the clamping frictional force cannot provide sufficient locking force to constrain the fiber bundle. This can easily lead to malfunctions such as fiber bundle de-anchoring and displacement during automatic roll changing, resulting in the failure of the roll changing action.

[0028] To resolve the above technical issues, please refer to Figures 1 to 7 As shown, the first embodiment of the present invention provides a fully automatic fiber winding device based on winding tension control, including a main body 1, which includes a conversion unit 12, a drive unit 13, a cutter 14 and a wire guide 15.

[0029] It also includes a guide mechanism 2, which includes a take-up shaft 21 with a guide assembly on it and a tension control wheel 22 on the main body 1. When the cutting blade 14 cuts the fiber, the instantaneous change in tension drives the tension control wheel 22 to swing, so that the guide assembly fixes the free end of the fiber to the take-up shaft 21. At the instant the cutting blade 14 cuts the fiber, the resistance at the take-up end disappears, causing the fiber tension to decrease instantaneously. However, the tension control wheel 22 has a very short feedback lag. Under the action of inertia, the tension control wheel 22 swings downward. The tension fluctuation of the tension control wheel 22 at the instant the cutting blade 14 cuts the fiber is used as the driving force to drive the guide assembly to fix the free end of the fiber without the need to introduce a new power source.

[0030] The guiding component includes a fixing block 23 fixedly connected to the take-up shaft 21. Multiple clamping blocks 24 are slidably connected to the rear end of the take-up shaft 21 via splines. The fixing block 23 and the clamping blocks 24 are both provided with slots 25. The slots 25 on the fixing block 23 are provided with anti-retraction parts 26. The slots 25 are formed in the mating area of ​​the fixing block 23 and the clamping blocks 24. The groove space inside the slot 25 is enclosed by the continuous zigzag contour of the clamping blocks 24 and the fixing block 23. The slot 25 as a whole presents a V-shape to adapt to the fiber bundle. The groove opening faces the fiber introduction direction. The inner wall of the groove cavity is a continuous bent contour. The groove width of the slot 25 matches the diameter of the fiber bundle. The groove depth can form a wrapping constraint on the fiber bundle.

[0031] A rotating shaft 27 is rotatably connected to the main body 1 via a torsion spring 214. A control rod 28 is fixedly connected to the front end of the rotating shaft 27. The end of the control rod 28 is inserted into the main body 1 and is hinged to a connecting rod 29. A vertical block 210 is hinged to the free end of the connecting rod 29. The rotating shaft 27 is located between the tension control wheel 22 and the end of the control rod 28. The rotating shaft 27 is the center of rotation. The tension control wheel 22 and the end of the control rod 28 swing in opposite directions.

[0032] The vertical block 210 is slidably connected to the main body 1. A contact block 211 is provided at the upper end of the vertical block 210. A push plate 212 is slidably connected inside the main body 1. An elastic element 213 is provided between the push plate 212 and the main body 1. The push plate 212 corresponds to the clamping block 24. When the contact block 211 moves upward to the push plate 212, it can push the clamping block 24 towards the fixed block 23. The vertical block 210 is slidably connected to the main body 1 and can only slide in the vertical direction. The elastic element 213 can be a spring or other elastic element 213. The end of the contact block 211 near the push plate 212 is an inclined surface, and the lower end of the push plate 212 is also an inclined surface. Figure 3 As shown, when the inclined surface of the contact block 211 moves upward to contact the inclined surface of the lower end of the push plate 212, the inclined surface cooperates to push the push plate 212 to move towards the clamping block 24, thereby pushing the clamping block 24 to move closer to the fixing block 23.

[0033] The conversion unit 12 includes a turntable 16 with a stop bar 17 on it. The cutting knife 14 is located between the stop bar 17 and the winding wheel. When the turntable 16 rotates, it can switch the winding of the take-up shaft 21 to ensure that the equipment does not stop. The stop bar 17 can guide and limit the winding path, making it easier for the cutting knife 14 to cut the fiber.

[0034] The conversion unit 12 includes a conversion block 18, on which a ball screw 19 is rotatably connected. The ball screw 19 drives the wire guide 15 to reciprocate. When the lead screw of the ball screw 19 rotates, the balls in the lead screw raceway roll along a spiral trajectory, causing the nut to move linearly along the lead screw axis. This causes the nut to drive the wire guide 15 to move linearly. The ball screw 19 achieves the reciprocating linear motion of the wire guide 15 by rotating in both directions. This is existing technology and will not be described in detail. The reciprocating movement of the wire guide 15 can arrange the fibers in an orderly manner along the axial direction of the roll, thereby allowing the fiber layer to evenly cover the surface of the roll and ensuring uniform roll density.

[0035] The main body 1 is equipped with a control module 110, which can control the operation of the drive unit 13. The drive unit 13 can control the rotation of the turntable 16, the rotation of the winding shaft 21, the rotation of the ball screw 19, the swing of the conversion block 18, the swing of the tension control wheel 22, and the forward and backward movement of the cutting blade 14. The above-mentioned drives are controlled independently by the control module 110, which is the prior art and will not be described in detail.

[0036] In use, when one of the take-up drums is fully loaded, the control module 110 first drives the fully loaded take-up shaft 21 to stop rotating, and then drives the cable guide 15 to move backward to the fixed block 23. The cable guide 15 drives the fiber backward to the slot 25 on the fixed block 23 and the clamping block 24. Since the slot 25 is V-shaped to fit the fiber bundle, the slot opening faces the fiber introduction direction, the inner wall of the slot cavity is a continuous bending profile, and the width of the slot matches the diameter of the fiber bundle, when the cable guide 15 drives the fiber to fold back and forth in the slot 25, the fiber bundle is embedded in the slot 25 to form a self-locking effect. The depth of the slot 25 cavity can form a wrapping constraint on the fiber bundle. The initial locking is completed, and the control module 110 drives the cutter 14 to move the stop bar 17 and the cable guide 15. The fiber is cut during the cutting operation. At the instant the cutting blade 14 cuts the fiber, the winding tension at the winding end suddenly disappears. At this moment, the fully wound take-up drum separates from the fiber, and the force balance of the fiber is instantly broken. After the tension at the winding end disappears, only the tensioner at the unwinding end maintains the damping force, and the effective tension of the fiber will decrease rapidly. Due to the sudden drop in tension, the tension of the fiber on the tension control wheel 22 weakens. The tension control wheel 22 will swing downward under its own weight and the force of the torsion spring 214. The tension control wheel 22 drives the control rod 28 to swing downward, causing the rotating shaft 27 to rotate clockwise and stretch the torsion spring 214. The end of the control rod 28 then drives the connecting rod 29 to swing upward. The connecting rod 29 drives the vertical block 210 to move upward. Because the tension control wheel 22 swings downward at the instant the cutting blade 14 cuts the fiber, the tension control wheel 22 is quickly reduced. Wheel 22 drives control lever 28 to swing significantly, causing vertical block 210 to move contact block 211 upward to push plate 212. When the inclined surface of contact block 211 moves upward to contact the inclined surface of the lower end of push plate 212, the inclined surface of contact block 211 pushes push plate 212 towards main body 1 clamping block 24 through the inclined surface of push plate 212 and compresses elastic element 213. Push plate 212 pushes the corresponding clamping block 24 towards fixed block 23. At this time, clamping block 24, through the squeezing of slot 25, pushes the fiber pre-clamped in slot 25 towards fixed block 23 for further clamping. Because the slot 25 of fixed block 23 is provided with a stop part 26, the stop part 26 inserts into the fiber in slot 25, further fixing the fiber. Due to the tension control wheel The instantaneous fluctuation of tension control wheel 22 causes it to swing downwards. Upon receiving this downward signal, control module 110 immediately adjusts the tensioner at the pay-off end, gradually increasing the fiber's damping force. As the tension recovers, the fiber's tension on tension control wheel 22 gradually returns to normal, causing it to swing back from the downward position to the center position until the tension stabilizes and returns to a balanced state. Tension control wheel 22 then drives control rod 28 to swing back, which in turn drives vertical block 210 downwards via connecting rod 29. Vertical block 210 causes contact block 211 to disengage from push plate 212, and push plate 212 resets under the force of elastic element 213. At this point, the free end of the fiber is fixed in slot 25, and control module 110 drives an unloaded take-up drum to perform a take-up operation on the fiber.Without introducing a new power source, the guide assembly secures the free end of the fiber by controlling the large fluctuations of the tension control wheel 22 during the instantaneous change in tension when the fiber is cut. Furthermore, the bent groove 25 and the anti-reverse portion 26 of the groove 25 further restrict the movement, effectively preventing the retainer from dislodging from the groove 25. Example 2

[0037] As can be seen from the above embodiments, tension fluctuations will occur in the fiber during the winding process. The tension fluctuations will inevitably be caused when the wire guide 15 changes direction. The reversal of the wire guide 15 is a dynamic process of "deceleration → stopping → reverse acceleration". During this process, the force balance of the fiber is broken by the mechanical motion characteristics. Tension fluctuations will lead to uneven wire spacing, fiber accumulation in the slack section and fiber tightening in the stretched section, affecting the consistency of subsequent cutting and composite forming.

[0038] To resolve the above technical issues, please refer to Figures 1 to 7 As shown, it also includes: an adjustment mechanism 3, which includes a tension adjustment component. When the cable guide 15 reverses direction, the tension adjustment component can predict the change in tension and pre-adjust the swing angle of the tension control wheel 22.

[0039] The tension adjustment assembly includes a synchronization block 31 that is synchronously arranged with the cable guide 15. The synchronization block 31 is connected to the cable guide 15 via a synchronization rod. A telescopic rod 32 is fixedly connected to the lower end of the synchronization block 31. A positioning block 33 located below the synchronization block 31 is provided inside the main body 1. A sliding groove 34 is provided on the positioning block 33. The telescopic rod 32 is slidably connected to the sliding groove 34. When the cable guide 15 moves back and forth, the synchronization block 31 located inside the main body 1 can move with the movement of the cable guide 15. The position of the conversion block 18 is not fixed and will swing, causing the position of the cable guide 15 to be not fixed. When the cable guide 15 drives the synchronization block 31 to swing through the synchronization rod, the synchronization block 31, through the telescopic rod 32 and the sliding groove 34 provided on the positioning block 33, allows the positioning block 33 to move only in the front and back direction with the synchronization block 31. The positioning block 33 will not swing with the conversion block 18.

[0040] An electric push rod 35 is fixedly connected below the positioning block 33. An adjusting block 36 is fixedly connected to the free end of the electric push rod 35. The adjusting block 36 can contact the contact block 211. There are two contact blocks 211, which are distributed in the front-back direction. The position of the contact block 211 corresponds to the limit position of the cable guide 15 reciprocating back and forth. The shape of the adjusting block 36 is an isosceles trapezoid, and both the front and rear end faces of the adjusting block 36 are inclined surfaces. The shape of the contact block 211 is a parallelogram. The inclined surfaces of the two contact blocks 211 are distributed in a figure-eight shape. When the adjusting block 36 moves to the corresponding contact block 211, the inclined surface of the adjusting block 36 can push the contact block 211 to move upward, so that the contact block 211 drives the end of the control rod 28 to swing upward around the rotating shaft 27 through the connecting rod 29, so that the control rod 28 drives the tension control wheel 22 to swing downward and stretch the torsion spring 214.

[0041] Based on the above embodiments, the reciprocating movement of the yarn guide 15 allows the fibers to be arranged orderly along the axial direction of the roll, thereby ensuring that the fiber layer evenly covers the surface of the roll and that the roll density is uniform. The reversal of the yarn guide 15 is a dynamic process of deceleration → stopping → reversal acceleration. When the yarn guide 15 reaches the end of its stroke, the drive unit 13 drives it to decelerate and brake, and the movement speed of the yarn guide 15 decreases rapidly. At this time, the winding end still winds up the fibers at a constant speed. The lag movement of the yarn guide 15 will cause the fibers to slack briefly. When the yarn guide 15 reaches the end of its stroke, the yarn guide 15 drives the synchronizing block 31 to move to the end of its stroke through the synchronizing rod. The telescopic rod 32 and the groove 34 on the positioning block 33 move the positioning block 33 to the end of its stroke in the front-back direction. The positioning block 33 then drives the adjusting block 36 to contact the corresponding contact block 211 via the electric push rod 35. Since the adjusting block 36 is an isosceles trapezoid with inclined surfaces on both its front and rear ends, and the contact block 211 is a parallelogram with the inclined surfaces of the two contact blocks 211 arranged in a figure-eight shape, when the adjusting block 36 moves to the corresponding contact block 211, the inclined surface of the adjusting block 36 can push the contact block 211 upward, causing the contact block 211 to drive the control rod 28 via the connecting rod 29. The end swings upward around the pivot 27, causing the control lever 28 to drive the tension control wheel 22 to swing downward and stretch the torsion spring 214. This allows the tension control wheel 22 to pre-tighten the fibers by swinging downward before the yarn guide 15 reverses direction, reducing tension fluctuations caused by the yarn guide 15 reversing. When the yarn guide 15 completes its deceleration and return, its movement becomes an acceleration motion. After braking, the yarn guide 15 immediately accelerates in the opposite direction, and the output torque of the drive unit 13 increases instantaneously. This causes the ball screw 19 to pull the yarn guide 15 in a rapid reverse motion, generating an instantaneous pulling force on the fibers, resulting in a sharp increase in tension and forming a reversing tension peak. To avoid tension fluctuations, when the cable guide 15 returns to its maximum stroke position, the electric actuator 35 pulls the adjusting block 36, causing the adjusting block 36 to disengage from the contact block 211. As the torsion spring 214 is stretched, the torsion spring 214 drives the rotating shaft 27 to rotate counterclockwise. The rotating shaft 27 drives the control lever 28 to swing counterclockwise. The control lever 28 drives the tension control wheel 22 to swing upward, predicting the peak tension and avoiding excessive stretching of the fiber, thus reducing tension fluctuations. When the cable guide 15 leaves the reversing limit position and the adjusting block 36 no longer corresponds to the contact block 211, the control module 110 drives the electric actuator 35 to reset the adjusting block 36 to the initial position.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
