Description

Technical Field

[0001] This application relates to the technical field of carbon fiber processing, and in particular to a carbon fiber winding device. Background Technology

[0002] In industrial production, the unwinding and rewinding of carbon fiber rolls is a common intermediate process. Its core purpose is to optimize the physical state of the carbon fiber roll, eliminate defects from previous processing, and adapt it to subsequent production requirements. Among these processes, the rewinding process is crucial, as it determines whether the internal tension of the carbon fiber roll is uniform, whether the interlayer arrangement is even, and whether it can meet the requirements of subsequent processes.

[0003] Patent application number CN202211093909.7 discloses a filament winding device for carbon fiber production, including a base at the bottom, a first support rod at the top of one end of the base, a guide wheel mounted at the top of the first support rod, a second support rod at the top of the other end of the base, a winding roller mounted at the top of the second support rod, and a winding motor with one end of the winding roller passing through the second support rod. It also includes a balancing mechanism, a cleaning mechanism, and an anti-static mechanism. Although it can wind the filaments, in this design, winding relies solely on the tension of the carbon fiber filaments themselves. This can easily lead to problems such as uncontrolled swaying or guide deviation of the carbon fiber filaments, resulting in localized overlap or excessive gaps between the filaments. Utility Model Content

[0004] To address the problem that existing carbon fiber winding equipment tends to have localized overlaps or excessive gaps in the carbon fiber filaments during the winding process, this application provides a carbon fiber winding device.

[0005] This application provides a carbon fiber winding device, which adopts the following technical solution:

[0006] The device includes a take-up roller for winding carbon fiber filaments and a mounting frame. The take-up roller is rotatably mounted on the mounting frame. The mounting frame is also rotatably mounted with a smoothing roller and a first guide assembly. The smoothing roller is in contact with the radial side of the take-up roller and rotates with the take-up roller. The first guide assembly is used to guide the carbon fiber filaments through the space between the smoothing roller and the take-up roller and onto the take-up roller. A swing seat is also rotatably mounted on the mounting frame. The take-up roller is mounted on the swing seat. When the swing seat rotates, it causes the take-up roller to come into contact with or move away from the smoothing roller. The swing seat uses its own weight to keep the take-up roller in contact with the smoothing roller.

[0007] By adopting the above implementation scheme, a smoothing roller is set next to the take-up roller, and the surfaces of the two are in close contact. This applies uniform pressure to the newly wound filament, pressing it onto the take-up roller to prevent carbon fiber filament deviation and ensuring that the carbon fiber filament winds along a preset trajectory, avoiding problems such as carbon fiber filament accumulation and misalignment. In this implementation scheme, the take-up roller is set on a rotatable swing seat, allowing it to rest against the smoothing roller under gravity. When it is necessary to replace the carbon fiber roll, simply rotating the swing seat allows the take-up roller to detach from the smoothing roller, facilitating disassembly. Furthermore, the swing seat uses gravity to keep the take-up roller in contact with the smoothing roller. As the diameter of the take-up roller increases, the thrust generated by the accumulation of carbon fiber filaments will automatically push the take-up roller upward, ensuring continuous contact between the two without the need for manual adjustment.

[0008] Preferably, the mounting frame includes a mounting plate, which has a working side and an installation side. The smoothing roller is rotatably mounted on the working side of the mounting plate, and the swing seat is rotatably mounted on the installation side of the mounting plate. The mounting plate has an arc-shaped hole connecting the front and rear sides. One end of the take-up roller is rotatably connected to the swing seat, and the other end passes through the arc-shaped hole into the working side of the mounting plate. The take-up roller is located above the pivot of the swing seat, and the swing seat tends to rotate around its pivot under the action of gravity.

[0009] By adopting the above implementation scheme, both the take-up roller and the smoothing roller are located on the working side of the mounting plate, and the swing seat is located on the mounting side of the mounting plate. The structure of the working side of the mounting plate is simpler, the path of carbon fiber winding is clearer, and the structures on both sides are prevented from interfering with each other. Since the take-up roller is located above the swing seat's rotating shaft, when the swing seat swings, if the center of gravity passes the swing seat's rotating shaft and is located on the side of the smoothing roller, the swing seat tends to swing towards the smoothing roller; if the center of gravity passes the swing seat's rotating shaft and is located on the side away from the smoothing roller, the swing seat tends to swing in a direction away from the smoothing roller. The take-up roller extends from the arc-shaped hole, so as the take-up roller swings with the swing seat, if it passes the swing seat's rotating shaft and is located on the side away from the smoothing roller, the take-up roller tends to swing towards the edge of the arc-shaped hole. However, under the limitation of the arc-shaped hole, the side wall of the arc-shaped hole can support the take-up roller. Therefore, under the action of gravity, the take-up roller can stably stop at the end of the arc-shaped hole away from the smoothing roller, which facilitates the replacement of the carbon fiber roll.

[0010] Preferably, the swing seat is provided with a handle, which extends through the arc-shaped hole to the working side of the mounting plate, and the handle is located on the side of the take-up roller away from the smoothing roller.

[0011] By adopting the above implementation scheme, the angle of the swing seat can be adjusted more conveniently via the handle, avoiding contact with the take-up roller during angle adjustment. The handle also extends to the working side of the mounting plate through the arc-shaped hole. When the take-up roller reaches the end of the arc-shaped hole away from the smoothing roller, the handle can rest against the end of the arc-shaped hole, preventing contact between the take-up roller and the arc-shaped hole. Since the take-up roller is rotatably mounted on the swing seat, contact between other structures and the take-up roller is reduced, decreasing the additional radial force on the take-up roller and preventing wear on the roller body surface, shaft deformation, or bearing overload caused by hard contact.

[0012] Preferably, the swing seat is equipped with a drive motor, which drives the take-up roller to rotate.

[0013] By adopting the above implementation scheme, the drive motor is set on the back side of the swing seat and rotates with the swing seat, which can drive the take-up roller more stably.

[0014] Preferably, the swing seat is further provided with a counterweight, which is located away from the swing seat pivot and close to the take-up roller.

[0015] By adopting the above implementation scheme, the pressure between the take-up roller and the smoothing roller is increased by the gravity of the counterweight.

[0016] Preferably, one end of the take-up roller is rotatably connected to the swing seat, and the other end is suspended; a core is sleeved on the take-up roller, and the carbon fiber filaments are wound around the surface of the core. The core is detachably fixed to the take-up roller by a fixing assembly; the fixing assembly includes a front retaining ring, a rear retaining ring, and a capped bolt sleeved on the take-up roller. The rear retaining ring is located at the end of the take-up roller near the swing seat, and the front retaining ring is detachably sleeved at the end of the take-up roller away from the swing seat. The core is located between the rear retaining ring and the front retaining ring; the suspended end of the take-up roller has a threaded hole along its axial direction, and the capped bolt is located in the threaded hole and presses against the front retaining ring, thereby fixing the core by the tightening force of the capped bolt.

[0017] Preferably, the first guide assembly includes a sliding platform and a guide roller disposed on the sliding platform. The sliding platform is driven by a screw module to reciprocate along the axial direction of the take-up roller, and the guide roller follows the movement of the sliding platform to spirally lay carbon fiber filaments on the take-up roller.

[0018] By adopting the above implementation scheme, the guide component for guiding carbon fiber filaments moves back and forth, and the carbon fiber filaments are spirally laid on the take-up roller. The take-up roller does not need to move axially, thus avoiding the axial displacement process of the take-up roller affecting the rotation axis of the take-up roller. The rotation of the take-up roller is more stable, and the carbon fiber roll is more uniform.

[0019] Preferably, a radial guide roller, an axial guide roller, and a plurality of inclined guide rollers are horizontally arranged on the sliding platform. The axis of rotation of the radial guide roller is perpendicular to the axis of rotation of the take-up roller. The axes of rotation of the axial guide roller and the plurality of inclined guide rollers are parallel to the axis of rotation of the take-up roller. The plurality of inclined guide rollers are arranged in a straight line to guide the carbon fiber filaments from the contact position between the take-up roller and the smoothing roller onto the take-up roller.

[0020] By adopting the above implementation scheme, since the entire sliding platform reciprocates along the axial direction of the take-up roller, the carbon fiber filament first passes through the radial guide roller. Therefore, the radial guide roller bears the force of the reciprocating motion of the carbon fiber filament first. The radial guide roller is perpendicular to the rotation axis of the take-up roller, which can better bear the force of the carbon fiber filament during the reciprocating motion of the sliding platform, reduce the lateral friction between the carbon fiber filament and the radial guide roller, and reduce the lateral force on the carbon fiber filament. The axial guide roller guides the carbon fiber filament to wind onto the inclined guide roller. Through the guidance of the inclined guide roller, the carbon fiber filament is squeezed by the smoothing roller just as it winds onto the lead roller, so that the carbon fiber filament can be wound more neatly on the take-up roller.

[0021] Preferably, the mounting frame is further rotatably equipped with an unwinding roller and a guide wheel for releasing the carbon fiber filaments; the mounting frame is further rotatably equipped with an unwinding roller and a guide wheel, the unwinding roller releases the carbon fiber filaments; the guide wheel is located above the unwinding roller, the axis of rotation of the guide wheel is perpendicular to the axis of rotation of the unwinding roller, and the plane of rotation of the guide wheel is located in the same plane as the unwinding direction of the carbon fiber filaments; the guide wheel is equipped with a speed sensor to detect the length of the carbon fiber filaments passing through.

[0022] Preferably, the mounting frame is further provided with a second guide assembly, which is disposed between the guide wheel and the first guide assembly, and guides the carbon fiber filament to the first guide assembly. The second guide assembly includes a first guide roller and a second guide roller rotatably disposed on the mounting frame. The first guide roller is disposed between the guide wheel and the first guide assembly, and the carbon fiber filament passes over the guide wheel and then passes over the first guide roller. The second guide roller is disposed below the first guide roller, with one end of the second guide roller near the unwinding roller rotatably disposed on the mounting frame, and the other end away from the unwinding roller inclined upward toward the first guide roller, and the axis of the second guide roller is perpendicular to the falling direction of the carbon fiber filament.

[0023] By adopting the above technical solution and setting a first guide roller, the carbon fiber filaments can be straightened after passing through the first guide roller downwards, thus improving the conveying stability and straightness. The rotation axis of the second guide roller is perpendicular to the downward movement trajectory of the carbon fiber filaments, preventing the second guide roller from exerting lateral force on the carbon fiber filaments.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The smoothing roller, which is set to fit the take-up roller, smooths the wound carbon fiber filaments to prevent local overlap or excessive gaps in the carbon fiber filaments caused by the carbon fiber filaments sticking up. By setting the take-up roller on the swing seat, the take-up roller can lean against the smoothing roller by gravity. The position of the take-up roller is automatically adjusted as the diameter of the take-up roller changes, so that the take-up roller always fits against the smoothing roller.

[0026] 2. The mounting plate simplifies the structure at the take-up roller position, making it easier to observe the winding process. The handle reduces the additional radial force on the take-up roller.

[0027] 3. A reciprocating sliding platform is installed, eliminating the need for reciprocating movement of the take-up roller, making the rotation of the take-up roller more stable and improving the quality of the carbon fiber roll. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail.

[0036] This application discloses a carbon fiber winding device.

[0037] Reference Figure 1 The application discloses a carbon fiber winding device, including a mounting frame 1. The mounting frame 1 includes a mounting plate 11, a support platform 12, and a support plate 13. The mounting plate 11 is a vertically arranged plate structure. The support platform 12 is located in the middle of the mounting plate 11, and the support plate 13 is located above the support platform 12 and on the top of the mounting plate 11. A winding roller 3 and a smoothing roller 4 are provided on the mounting plate 11. When the winding roller 3 rotates, it pulls the carbon fiber filament 9, causing the carbon fiber filament 9 to wind onto the winding roller 3. The smoothing roller 4 is in contact with the radial side of the winding roller 3 to smooth the carbon fiber filament 9. A first guide component 5 is provided on the support platform 12 to guide the carbon fiber filament 9, and a second guide component 8 is provided on the support plate 13 to guide the carbon fiber filament 9. An unwinding roller 6 is also provided on the mounting plate 11 to release the carbon fiber filament 9. The carbon fiber filament 9 is guided by the second guide component 8 and the first guide component 5 in sequence before winding onto the winding roller 3. During the winding process, the smoothing roller 4 always stays in contact with the winding roller 3. The smoothing roller 4 smooths the carbon fiber filaments 9 wrapped on the winding roller 3, preventing the carbon fiber filaments 9 from shifting, thereby avoiding local overlap or excessive gaps in the carbon fiber filaments 9 during the winding process.

[0038] Reference Figure 1The smoothing roller 4 is arranged parallel to the take-up roller 3. The smoothing roller 4 is in contact with the radial side of the take-up roller 3 and rotates with the take-up roller 3, smoothing the carbon fiber filaments 9 wound on the take-up roller 3. A swing seat 2 is also rotatably mounted on the mounting frame 1. The swing seat 2 is mounted on the mounting frame 1 via a swing seat shaft 23. The take-up roller 3 is mounted on the swing seat 2. When the swing seat 2 rotates, it drives the take-up roller 3 to swing, so that the take-up roller 3 is in contact with or away from the smoothing roller 4. The smoothing roller 4 is located on the swing trajectory of the take-up roller 3. The swing seat 2 can rely on its own weight to keep the take-up roller 3 in contact with the smoothing roller 4. During the winding process, as the diameter of the take-up roller 3 increases, the wound carbon fiber filaments 9 automatically lift the take-up roller 3. Therefore, the take-up roller 3 always stays in contact with the smoothing roller 4 during the winding process. When it is necessary to disassemble the carbon fiber roll, simply rotate the swing seat 2 to move the take-up roller 3 away from the smoothing roller 4, which facilitates the disassembly of the carbon fiber roll.

[0039] Reference Figure 1 and 2 The mounting plate 11 includes a working side and an installation side. The installation side of the mounting plate 11 is located inside a housing, which protects the structure installed on the installation side. The smoothing roller 4 is rotatably mounted on the working side of the mounting plate 11, and the swing seat 2 is mounted on the installation side of the mounting plate 11 via the swing seat shaft 23. The mounting plate 11 has an arc-shaped hole 111 connecting the working side and the installation side. One end of the take-up roller 3 is rotatably connected to the swing seat 2, and the other end passes through the arc-shaped hole 111 into the working side of the mounting plate 11. When the swing seat 2 swings around its shaft, the take-up roller 3 swings within the arc-shaped hole 111. The take-up roller 3 is located above the shaft of the swing seat 2. The upper part of the swing seat 2 is heavier, so under the action of gravity, the swing seat 2 tends to swing around its shaft. When the take-up roller 3 swings toward the smoothing roller 4, it can eventually rest stably against the smoothing roller 4, relying on its own weight to adhere to the smoothing roller 4 and remain stable.

[0040] Reference Figure 3The swing seat 2 is plate-shaped, with a smaller upper part and a larger lower part. The pivot of the swing seat 2 is located at its lower part, and the take-up roller 3 is installed on the upper part of the swing seat 2. A drive motor 33 is also installed on the upper part of the swing seat 2. The drive motor 33 is located on the mounting side of the mounting plate 11, and drives the take-up roller 3 to rotate and take up the roller. Therefore, the upper part of the swing seat 2 is heavier, making the take-up roller 3 more stable when placed on the smoothing roller 4. A counterweight 21 is also provided on the upper part of the swing seat 2. The counterweight 21 is located away from the pivot 23 of the swing seat and close to the take-up roller 2. The weight of the counterweight 21 increases the compressive force between the take-up roller 3 and the smoothing roller 4. A handle 22 is provided on the swing seat 2. The handle 22 extends through the arc-shaped hole 111 to the working side of the mounting plate 11. Holding the handle 22 allows for adjustment of the angle of the swing seat 2, avoiding direct contact with the take-up roller 3. The handle 22 is located on the side of the take-up roller 3 away from the smoothing roller 4. When the take-up roller 3 swings toward the end away from the smoothing roller 4, the handle 22 will eventually abut against the edge of the arc-shaped hole 111, relying on gravity to adhere to the edge of the arc-shaped hole 111 and remain stable.

[0041] Reference Figure 4 A core 31 is detachably fixed to the take-up roller 3. Carbon fiber filaments 9 are wound around the core 31 to form a carbon fiber roll. One end of the take-up roller 3 is rotatably connected to the swing seat 2, and the other end is suspended. The core 31 is detachably fixed to the take-up roller 3 by a fixing assembly 32. The fixing assembly 32 includes a front retaining ring 321 and a rear retaining ring 322 sleeved on the take-up roller 3. The rear retaining ring 322 is fixed to the end of the take-up roller 3 near the swing seat 2, and the front retaining ring 321 is detachably sleeved on the take-up roller 3 away from the swing seat. At one end of 2, the core 31 is disposed between the rear retaining ring 322 and the front retaining ring 321; the fixing assembly 32 also includes a capped bolt 323, and the suspended end of the take-up roller 3 has a threaded hole along its axial direction. The capped bolt 323 is disposed in the threaded hole. The take-up roller 3 extends from the side of the front retaining ring 321 away from the core 31, so that when the capped bolt 323 is tightened, the nut of the capped bolt 323 can contact and press the front retaining ring 321, and fix the core 31 by the tightening force of the bolt.

[0042] Reference Figure 5The support platform 12 is fixed to the working side of the mounting plate 11, and the smoothing roller 4 is rotatably mounted on the support platform 12. The support platform 12 is also equipped with a first guide assembly 5, which includes a sliding platform 51 and multiple guide rollers 52 disposed on the sliding platform 51. The sliding platform 51 is driven by the screw module 53 to reciprocate along the axial direction of the take-up roller 3. The multiple guide rollers 52 follow the movement of the sliding platform 51 to spirally lay the carbon fiber filament 9 onto the take-up roller 3. The screw module 53 includes a servo motor, a ball screw, and a slider, and the sliding platform 51 is fixed on the slider. A radial guide roller 521, an axial guide roller 522, and multiple inclined guide rollers 523 are horizontally arranged on the sliding platform 51. The axis of rotation of the radial guide roller 521 is perpendicular to the axis of rotation of the take-up roller 3. The axes of rotation of the axial guide roller 522 and multiple inclined guide rollers 523 are parallel to the axis of rotation of the take-up roller 3. The multiple inclined guide rollers 523 are arranged in a straight line to guide the carbon fiber filament 9 from the contact position between the take-up roller 3 and the smoothing roller 4 onto the take-up roller 3.

[0043] Reference Figure 6 A guide wheel 7 is rotatably mounted on the support plate 13, positioned above the unwinding roller 6. The axis of rotation of the guide wheel 7 is perpendicular to that of the unwinding roller 6, and the plane of rotation of the guide wheel 7 is on the same plane as the unwinding direction of the carbon fiber filament 9. A speed sensor 71 is mounted on the guide wheel 7 and fixed to the support platform 12. The speed sensor 71 detects the number of rotations of the guide wheel 7, thereby detecting the length of the carbon fiber filament 9. In this embodiment, reflective areas are alternately arranged on the side of the guide wheel 7, and the speed sensor 71 uses the principle of light reflection to achieve non-contact counting. When the carbon fiber filament 9 is guided by the guide wheel 7, it experiences minimal lateral force, making it less prone to cracking or burr formation.

[0044] Reference Figure 6 The second guide assembly 8 is disposed between the guide wheel 7 and the first guide assembly 5, and guides the carbon fiber filament 9 to the first guide assembly 5 through the second guide assembly 8. The second guide assembly 8 includes a first guide roller 81 rotatably disposed on the support plate 13, and the first guide roller 81 is disposed between the guide wheel 7 and the first guide assembly 5. The carbon fiber filament 9 passes over the guide wheel 7 and passes over the first guide roller 81. The second guide assembly 8 also includes a second guide roller 82 disposed on the support plate 13, and the second guide roller 82 is disposed below the first guide roller 81. The end of the second guide roller 82 near the unwinding roller 6 is rotatably disposed on the support plate 13, and the end away from the unwinding roller 6 is inclined upward toward the first guide roller 81, and the axis of the second guide roller 82 is perpendicular to the falling direction of the carbon fiber filament 9.

[0045] The implementation principle of this application embodiment is as follows: The carbon fiber filament 9 passes upward from the unwinding roller 6 or other container storing the filament and wraps around the guide wheel 7. Since the rotation axis of the guide wheel 7 is perpendicular to the rotation axis of the unwinding roller 6, the carbon fiber filament 9 is less prone to lateral friction during unwinding. Then, the carbon fiber filament 9 passes over the first guide roller 81 from above, and then downward from the side of the first guide roller 81, resting on the side of the second guide roller 82. Since the axis of the second guide roller 82 is perpendicular to the downward movement direction of the carbon fiber filament 9, the lateral force on the carbon fiber filament 9 is small, and burrs are less likely to form. The carbon fiber filament 9 passes downward through the lead roller 52, then passes between the smoothing roller 4 and the take-up roller 3, and then winds onto the take-up roller 3. During the winding process, the sliding platform 51 reciprocates along the axis of the take-up roller 3 via the lead screw module 53, winding the carbon fiber filament 9 onto the take-up roller 3. After winding is complete, hold the handle 22 and pull the swing seat 2 to rotate, so that the winding roller 3 is separated from the smoothing roller 4. Remove the cap bolt 323 installed on the winding roller 3, and remove the front retaining ring 321. Then the carbon fiber roll can be removed, and the disassembly of the carbon fiber roll is completed.

[0046] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
