Description

Technical Field

[0001] This invention relates to the field of fiber processing equipment, and more particularly to a fiber winding device. Background Technology

[0002] In industries such as textiles and composite materials, which require the processing and production of fibers, fibers are usually guided or wound and collected by rollers to facilitate changing the direction of the fibers during production and to enable the fibers to work with the machine for continuous output.

[0003] In the prior art, the roller is usually set to be cylindrical. When the fiber passes around, it needs to be bent to fit the curved surface of the roller, which leads to stress concentration and fiber deformation. When the fiber is picked up, it cannot be made completely straight, which in turn leads to a reduction in processing quality. Summary of the Invention

[0004] To overcome the problems existing in related technologies, the present invention provides a fiber winding device, the fiber winding device comprising: A fiber feeding mechanism is used to unwind fibers; A winding mechanism is provided for winding the fibers unwound from the feeding mechanism. The winding mechanism includes a rotating shaft and a plurality of shaped rollers fixed to the rotating shaft. The plurality of shaped rollers are distributed circumferentially along the rotating shaft. Each pair of adjacent shaped rollers cooperates to form a winding plane. The plurality of winding planes are connected end to end in sequence along the circumferential direction of the rotating shaft. The winding plane is used to support the fibers wound on the winding mechanism.

[0005] In some embodiments, the shaped roller is a triangular prism structure. The outer surface of the triangular prism structure includes a bottom surface, a first support surface, and a second support surface that are connected end to end in sequence. The bottom surface of each shaped roller faces the rotation axis. Along the circumferential direction of the rotation axis, the first support surface and the second support surface of the plurality of shaped rollers are alternately distributed in sequence. The first support surface of each shaped roller and the second support surface of the adjacent shaped roller are on the same plane to jointly form a winding plane.

[0006] In some embodiments, a rounded corner structure is provided between the first supporting surface and the second supporting surface of each of the shaped rollers.

[0007] In some embodiments, the radius of the fillet is greater than 0 and less than or equal to 0.2 mm; and / or, The width of the first support surface and the width of the second support surface are both greater than or equal to 20 mm.

[0008] In some embodiments, multiple winding planes are connected end to end in sequence to form a regular polygonal structure.

[0009] In some embodiments, the outer surfaces of the plurality of shaped rollers are provided with a wear-resistant coating.

[0010] In some embodiments, the fiber winding device further includes: A tension adjustment mechanism is disposed between the yarn feeding mechanism and the winding mechanism, and the tension adjustment mechanism is used to adjust the tension of the fiber.

[0011] In some embodiments, the fiber winding device further includes: An impregnation mechanism is disposed between the yarn feeding mechanism and the winding mechanism. The impregnation mechanism is used to impregnate the fibers unwound from the yarn feeding mechanism, and the impregnated fibers are wound around the winding mechanism.

[0012] In some embodiments, the adhesive application mechanism includes: Glue tank, the glue tank being used to hold glue liquid; A limiting roller is disposed in the glue tank, and the limiting roller is used to immerse the fiber in the glue solution.

[0014] The beneficial effects of the present invention are as follows: by setting multiple irregularly shaped rollers and making each pair of adjacent irregularly shaped rollers cooperate to form a winding plane, the multiple winding planes are connected end to end in sequence along the circumferential direction of the rotation axis. The winding plane can support the fiber wound on the winding mechanism, so that each segment of the fiber on the winding plane can remain straight, avoiding the phenomenon of reduced processing quality caused by the fiber's inability to return to straightness due to bending stress.

[0018] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0019] In the process of processing and producing fibers, fibers usually need to be guided or wound and collected by rollers, so that the direction of the fibers can be changed during production and the fibers can be continuously output in cooperation with the machine.

[0020] In existing structures, the roller is usually set to be cylindrical. When the fiber passes around, it needs to be bent to fit the curved surface of the roller, which leads to stress concentration and fiber deformation. When the fiber is picked up, it cannot be made completely straight, which in turn leads to a reduction in processing quality.

[0021] To address the problems existing in related technologies, this disclosure provides a fiber winding device in exemplary embodiments, such as... Figure 1 As shown, the fiber winding device includes a fiber feeding mechanism 1 and a winding mechanism 2. The fiber feeding mechanism 1 is used to unwind the fiber. The fiber roll is placed on the fiber feeding mechanism 1, which can be configured as an active or passive fiber feeding mechanism. The winding mechanism 2 is used to wind the fiber unwound from the fiber feeding mechanism 1. The winding mechanism 2 includes a rotating shaft 21 and multiple irregularly shaped rollers 22 fixed to the rotating shaft 21. The shape of the irregularly shaped rollers 22 can be arbitrarily set. The multiple irregularly shaped rollers 22 are distributed at intervals along the circumference of the rotating shaft 21. Each pair of adjacent irregularly shaped rollers 22 cooperate to form a winding plane. The multiple winding planes are connected end to end along the circumferential direction of the rotating shaft 21. The winding planes are used to support the fiber wound on the winding mechanism 2. The multiple winding planes connected end to end form a closed shape structure. For example, the multiple winding planes connected end to end form a hollow columnar structure. The cross-sectional shape of the columnar structure perpendicular to the extension direction of the columnar structure is polygonal. The closed shape structure can be a regular polygonal structure or a general polygonal structure, without specific limitation.

[0022] In practical use, if the fiber is not needed for immediate production, the fiber can be unloaded from the feeding mechanism 1 and wound onto the winding mechanism 2. The winding plane supports the fiber, preventing it from remaining bent and unable to straighten. When the fiber needs to be used immediately for production, the winding mechanism 2 can be used to guide the fiber output from the feeding mechanism 1. During the guiding process, the winding plane supports the fiber, allowing it to straighten. To enhance the straightening effect, multiple winding mechanisms 2 can be used to allow the fiber to pass through sequentially, or the fiber can be wound multiple times in the winding mechanism 2 before being output to the next process.

[0023] In one example, such as Figure 1 As shown, the fiber feeding mechanism 1 includes a fiber feeding bracket 11 and a fiber feeding shaft 12. The fiber feeding shaft 12 is rotatably mounted on the fiber feeding bracket 11 via a fixed bearing, and the fiber is wound on the fiber feeding shaft 12. When the fiber is pulled outward by an external force, the fiber feeding shaft 12 will rotate with the external force to smoothly feed the fiber out.

[0024] In one example, the yarn feeding mechanism 1 also includes a yarn feeding drive unit (not shown in the figure). The power output end of the yarn feeding drive unit is connected to the yarn feeding shaft 12. During yarn feeding, the yarn feeding drive unit can drive the yarn feeding shaft 12 to rotate actively, adaptively releasing and retracting fibers to adjust the fiber tension. For example, when the amount of fiber released is too small, the fibers are too tight and prone to breakage. In this case, by driving the yarn feeding shaft 12 to rotate to release more fibers, the tension on the fibers can be reduced, preventing fiber breakage. When the amount of fiber released is too large, the fibers are too loose and prone to bending, causing the fibers to become tangled or get caught in other equipment, resulting in equipment damage. In this case, by driving the yarn feeding shaft 12 to rotate in the opposite direction to tighten the fibers, the fibers can be restored to a taut and straight state. The yarn feeding drive unit can be configured in any form capable of driving the yarn feeding shaft 12 to rotate, such as a motor.

[0025] In one example, such as Figure 1As shown, to further adjust the fiber tension, the fiber winding device also includes a tension adjusting mechanism 3, which is located between the feeding mechanism 1 and the winding mechanism 2. The tension adjusting mechanism 3 includes a tension adjusting roller and an adjusting drive unit. The tension adjusting roller is located at the power output end of the adjusting drive unit, and the adjusting drive unit drives the tension adjusting roller to move vertically. After the fiber is drawn out from the feeding mechanism 1, it passes over the tension adjusting roller from above and is then fed to the winding mechanism 2. When the fiber tension is too high, the tension adjusting roller moves downward to shorten the distance the fiber needs to travel from the feeding mechanism 1 to the winding mechanism 2, thereby reducing the fiber tension. Similarly, when the fiber tension is too low, causing the fiber to bend due to lack of tension, the tension adjusting roller moves upward, increasing the distance the fiber needs to travel from the feeding mechanism 1 to the winding mechanism 2, thereby increasing the fiber tension and causing the fiber to straighten again.

[0026] In one example, the fiber winding device also includes a tension testing unit mounted on a tension adjusting roller. This unit measures the pressure between the fiber and the roller to monitor and control the fiber tension in real time. Before operation, a target pressure value is input to the tension testing unit. When the measured pressure is less than the target value, the fiber tension is low. The tension adjusting roller then moves upward, increasing the fiber tension until the pressure equals the target value, thus maintaining a moderate fiber tension. Similarly, when the measured pressure is greater than the target value, the fiber tension is high. The tension adjusting roller then moves downward, decreasing the fiber tension until the pressure equals the target value. The tension testing unit can be configured with a pressure sensor or other device capable of measuring force.

[0027] In one example, such as Figure 2 As shown, the shaped roller 22 has a triangular prism structure. The number of sides of the prism is moderate, which allows for the formation of a continuous winding plane through a reasonable arrangement, without causing the shaped roller 22 to become too large or heavy due to an excessive number of sides. This avoids the problem of excessive load on the rotating shaft 21 and increased energy consumption. While ensuring the above effects, the simple structure of the triangular prism also makes the processing of the shaped roller 22 easier, facilitating production. The outer surface of the triangular prism structure includes a bottom surface, a first support surface 221, and a second support surface 222 connected end to end. The bottom surface of each shaped roller 22 faces the rotating shaft 21. The connection method between the bottom surface of the shaped roller 22 and the rotating shaft 21 can be arbitrarily set, such as bolted connection or welded connection, to ensure a firm connection without loosening.

[0028] The first supporting surface 221 and the second supporting surface 222 form a certain angle. The size of this angle is determined according to the number of shaped rollers 22 and the shape of the winding plane. For example, when six shaped rollers 22 are set, the angle is 120° to ensure that the supporting surfaces of adjacent shaped rollers 22 can form a continuous regular hexagonal winding plane. Along the circumferential direction of the rotation axis 21, the first supporting surface 221 and the second supporting surface 222 of the multiple shaped rollers 22 are alternately distributed in sequence. That is, the first supporting surface 221 of the first shaped roller 22 is adjacent to the second supporting surface 222 of the second shaped roller 22, the first supporting surface 221 of the second shaped roller 22 is adjacent to the second supporting surface 222 of the third shaped roller 22, and so on. The first supporting surface 221 of each shaped roller 22 and the second supporting surface 222 of the adjacent shaped roller 22 are on the same plane to jointly form a winding plane. For example, there are six triangular prism-shaped rollers 22. The engagement process is as follows: the first support surface 221 of the first shaped roller 22 is coplanar with the second support surface 222 of the second shaped roller 22, forming a winding plane; the first support surface 221 of the second shaped roller 22 is coplanar with the second support surface 222 of the third shaped roller 22, forming a second winding plane; and so on, the six shaped rollers 22 form a total of six winding planes, and the six winding planes are connected end to end along the circumference of the rotation axis 21 to form a continuous hexagonal winding support surface.

[0029] In one example, such as Figure 1 As shown, the bottom surfaces of the triangular prism-shaped rollers 22 can also be configured to be separated from each other, that is, a gap is left between the first support surface 221 and the second support surface 222 of two adjacent shaped rollers 22. The first support surface 221, the second support surface 222, and the gap between them together form a winding plane. This configuration can reduce the weight of the shaped rollers 22, reduce the pressure on the rotating shaft 21, and improve the service life of the rotating shaft 21. At the same time, the fibers will remain taut under the support of the shaped rollers 22, and the gap between the first support surface 221 and the second support surface 222 will not cause the fibers to bend under gravity, thus not affecting the original technical effect.

[0030] In one example, multiple winding planes are sequentially connected end-to-end to form a regular polygonal structure. When multiple shaped rollers 22 are evenly distributed circumferentially along the rotation axis 21, and the first support surface 221 of each shaped roller 22 is coplanar with the second support surface 222 of the adjacent shaped roller 22, the multiple winding planes will naturally form a regular polygon. The shape of the regular polygonal structure can be arbitrarily set, and the shape of the regular polygonal structure is related to the number of shaped rollers 22. For example, when four shaped rollers 22 are set, the winding plane forms a regular quadrilateral; when six shaped rollers 22 are set, a regular hexagon is formed; and when eight shaped rollers 22 are set, a regular octagon is formed. By setting the shape formed by the sequential connection of multiple winding planes to a regular polygonal structure, the fibers located on each winding plane can be subjected to balanced force and the winding can be stable. It can also prevent the multiple shaped rollers 22 from generating centrifugal rotation, which would increase the force on the rotation axis 21 and reduce its service life.

[0031] In one example, such as Figure 1 As shown, the shaped roller 22 is fixedly connected to the rotating shaft 21 via a connecting rod 23. By setting the connecting rod 23, the distance between the two furthest sides of the adjacent first support surface 221 and second support surface 222 can be changed without changing the size of the shaped roller 22, thereby increasing the area of ​​the winding plane and allowing the fibers to remain straight over a longer distance. The connecting rod 23 can also be configured as a telescopic rod structure, and the area of ​​the winding plane can be controlled by changing the length of the connecting rod 23.

[0032] In one example, such as Figure 2 As shown, each shaped roller 22 has a rounded corner structure between its first supporting surface 221 and second supporting surface 222. This rounded corner structure is located at the intersection of the first supporting surface 221 and the second supporting surface 222, making the transition between them smoother. By providing this rounded corner structure, the fibers will not be scratched or worn at the right-angled edges when passing through the junction of the first supporting surface 221 and the second supporting surface 222, preventing strength loss or even breakage due to fiber surface damage and effectively protecting the fiber's integrity. Simultaneously, the rounded corner structure also prevents the fibers from bending at right angles, avoiding excessive bending angles that could cause other parts of the fiber to bend due to internal fiber stress.

[0033] The machining method for rounded corner structures can be chosen arbitrarily, but it must be ensured that the rounded corner surface is smooth and burr-free, such as by using a CNC milling machine to perform arc transition machining.

[0034] In one example, the radius of the fillet is greater than 0 and less than or equal to 0.2 mm; and / or, the width of the first support surface 221 and the width of the second support surface 222 are both greater than or equal to 20 mm.

[0035] The selection of the fillet radius needs to comprehensively consider both the fiber protection effect and the flatness of the winding plane. If the radius is 0, the fillet structure disappears, and the joint of the supporting surface returns to a right angle, failing to protect the fiber. Therefore, the radius must be greater than 0. If the radius is too large (e.g., exceeding 0.2mm), the fillet structure will form a significant protrusion at the joint of the supporting surface, causing the winding plane to become concave or uneven. During the winding process, the fiber is prone to slipping or uneven stress at the protrusion, affecting the winding accuracy. Therefore, through extensive experimental verification, when the radius is controlled within the range of 0-0.2mm, it can effectively protect the fiber while ensuring the flatness of the winding plane.

[0036] The selection of the support surface width is mainly based on the required contact area between the fiber and the support surface. If the support surface width is too small (e.g., less than 20mm), the contact area between the fiber and the support surface is too small, increasing the pressure per unit area and easily leading to excessive local pressure on the fiber, causing damage. Simultaneously, a small contact area reduces the friction between the fiber and the support surface, increasing the risk of fiber slippage and affecting winding stability. When the widths of both the first support surface 221 and the second support surface 222 are greater than or equal to 20mm, the contact area between the fiber and the support surface increases significantly, reducing the pressure per unit area and effectively preventing fiber damage. At the same time, increased friction reduces the risk of fiber slippage and improves winding stability. In actual use, the widths of the first support surface 221 and the second support surface 222 can be adjusted according to actual needs. For example, when the winding speed is high, the widths of the first support surface 221 and the second support surface 222 can be increased to reduce local pressure on the fiber and increase the friction between the fiber and the first and second support surfaces 221 and 222, ensuring smooth operation.

[0037] In one example, the outer surfaces of multiple shaped rollers 22 are all coated with a wear-resistant coating. By applying this coating, the service life of the shaped rollers 22 can be extended, preventing fiber damage due to surface wear. The material of the wear-resistant coating can be chosen arbitrarily according to actual needs, such as tungsten carbide or alumina ceramic, etc., without further limitations.

[0038] In one example, such as Figure 1 As shown, the fiber winding device also includes an impregnation mechanism 5, which is disposed between the fiber feeding mechanism 1 and the winding mechanism 2. The impregnation mechanism 5 is used to impregnate the fibers unwound from the fiber feeding mechanism 1, and the impregnated fibers are then wound onto the winding mechanism 2. By providing the impregnation mechanism 5 between the fiber feeding mechanism 1 and the winding mechanism 2, the fibers unwound from the fiber feeding mechanism 1 can be uniformly impregnated, thereby improving the performance of subsequent products.

[0039] In one example, the impregnation mechanism 5 includes an adhesive tank 51 and a limiting roller 52. The adhesive tank 51 holds the adhesive solution, and the limiting roller 52 is disposed on the adhesive tank 51 to restrict the fiber path within the adhesive tank 51, allowing the fibers to be immersed in the adhesive solution for uniform and complete impregnation. The material of the adhesive tank 51 can be arbitrarily set according to actual needs. In this example, the adhesive tank 51 is made of stainless steel, giving it good corrosion resistance and preventing reaction with the adhesive solution.

[0040] In one example, the impregnation mechanism 5 also includes a heating component and a temperature sensor, which are disposed in the adhesive tank 51. When the ambient temperature is too low, the low temperature will significantly reduce the fluidity of the adhesive, resulting in ineffective impregnation of the fibers. By setting up the heating component, the adhesive can be heated, ensuring that the adhesive maintains good fluidity and facilitating fiber impregnation. Simultaneously, the temperature sensor can monitor the temperature of the adhesive in real time. When the adhesive temperature is detected to be too low, the heating component is activated to heat the adhesive; when the adhesive temperature is detected to reach the preset temperature, the heating component is deactivated to prevent excessively high temperatures from altering the adhesive properties. The heating component can be any device capable of heating the adhesive, such as an electric heating wire.

[0041] In one example, the impregnation mechanism 5 also includes a liquid level sensor and a limit drive unit. The liquid level sensor and the limit drive unit are disposed within the glue tank 51. The power output end of the limit drive unit is connected to a limit roller 52, used to drive the limit roller 52 to move vertically along the glue tank 51. When the liquid level sensor detects a drop in the glue level, it controls the limit drive unit to activate, controlling the limit roller 52 to move downwards, ensuring the fibers are always immersed in the glue. When the liquid level sensor detects that the glue level is too low, it issues an alarm to remind the operator to add glue. After adding glue, the glue level rises, and the liquid level sensor controls the limit roller 52 to move upwards to reset, repeating the aforementioned process. The liquid level sensor can be any component capable of detecting liquid level height, such as a float-type liquid level sensor.

[0042] In one example, such as Figure 1 As shown, the fiber winding device also includes a guide roller 4, which is disposed between the fiber feeding mechanism 1 and the winding mechanism 2. The guide roller 4 is used to guide the fiber's direction of travel. By setting the guide roller 4, the fiber's direction of travel can be changed, allowing the fiber to smoothly pass through multiple structures along a preset path before entering the winding mechanism 2. Multiple guide rollers 4 can be provided to change the fiber's direction of travel multiple times.

[0043] In one example, such as Figure 1As shown, the fiber winding device also includes a frame 6. All other components of the fiber winding device are mounted on the frame 6 according to their arrangement, making all components a single unit, facilitating the handling and use of the fiber winding device. The frame 6 can be configured in any form according to actual needs, such as a flat steel plate or an irregular structure.

[0044] In summary, by setting multiple irregularly shaped rollers 22, and having each pair of adjacent irregularly shaped rollers 22 cooperate to form a winding plane, and having these multiple winding planes connected end-to-end along the circumferential direction of the rotation axis 21, the winding planes can support the fibers wound on the winding mechanism 2, ensuring that each segment of the fiber on the winding plane remains straight. This avoids the phenomenon of reduced processing quality caused by the fiber's inability to return to straightness due to bending stress. Simultaneously, by setting tension adjustment mechanisms 3 and impregnation mechanisms 5, the smooth progress of the fiber winding process can also be guaranteed.
