Description

Technical Field

[0001] This utility model relates to the field of yarn spreading roller technology, specifically a horizontal vibration component for working yarn spreading rollers. Background Technology

[0002] Carbon fiber composites are widely used in high-end manufacturing fields such as aerospace, new energy vehicles, and wind turbine blades due to their excellent properties such as lightweight, high strength, corrosion resistance, and high temperature resistance. With the increasing demands for material performance from industrial upgrading, the demand for low areal density prepregs is growing daily.

[0003] However, the limitations of existing carbon fiber spreading devices severely restrict the quality of mass production of such products:

[0004] (1) Insufficient uniformity of fiber dispersion

[0005] Traditional yarn spreading devices mostly adopt a fixed or single vibrating yarn spreading rod design, which makes it difficult to achieve uniform spreading at the single filament level for low areal density products (such as filament bundles below 12k). The initial agglomeration effect caused by the adhesion of fiber bundles before entering the spreading area leads to a prepreg areal density deviation of more than ±3%, and even fiber overlap or void defects in some areas, which seriously affects the consistency of mechanical properties of composite materials.

[0006] (2) Lack of dynamic regulation capability

[0007] Existing yarn spreading rollers are mostly fixed or have simple lifting structures, lacking an adaptive adjustment mechanism for the dynamic deformation of fiber bundles. During the yarn spreading process, fiber bundles are prone to buckling deformation due to tension fluctuations, resulting in uncontrollable yarn spreading paths. This makes it difficult to meet the flattening requirements of high-precision irregular cross-section fibers, thus restricting the application of advanced processes such as multi-axial weaving.

[0008] (3) Low thermal energy utilization efficiency

[0009] Traditional yarn spreading devices often employ overall constant temperature control, failing to consider the differences in thermal expansion between different resin systems. During the high-temperature impregnation stage, microcracks are easily generated at the fiber-matrix interface due to thermal stress mismatch, leading to a decrease in the interlaminar shear strength of the composite material.

[0010] (4) Bottleneck in cleaning processes

[0011] Existing equipment lacks active cleaning capabilities, making it difficult to effectively remove residual sizing agents and impurities from the fiber surface.

[0012] Therefore, it is necessary to propose a horizontal vibration assembly for the operation of the yarn spreading roller. Utility Model Content

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] In recent years, carbon fiber composites have seen rapid market demand growth due to their unique characteristics such as high strength, low density, corrosion resistance, and aging resistance. In the production process of carbon fiber composites, the spreading device is crucial to ensure stable areal density parameters and consistent mechanical properties of the prepreg. The main function of the spreading device is to evenly spread the carbon fiber bundles. Before entering the spreading device, each fiber filament of the carbon fiber bundle is bonded together; for example, a 12k fiber bundle consists of 12,000 individual fibers bonded together. If these unspread fibers are directly used to produce prepreg, the areal density will be uneven, with some areas having higher or lower densities. This results in highly unstable mechanical properties, and products made from such prepreg will be substandard. This is especially true when producing low areal density products, requiring a smaller number of fiber bundles while simultaneously spreading each bundle and ensuring each fiber filament is evenly distributed. Therefore, the arrangement of the spreading rods and the functions of each spreading rod are paramount.

[0040] The yarn spreading device mainly consists of multiple sets of yarn spreading rods. The yarn spreading rod arrangement process applied for here consists of 10 yarn spreading rods, and each yarn spreading rod has a different process function. The fiber is produced in accordance with a specific process path in the 10 yarn spreading rods, and under the action of the vibration function of the yarn spreading rods, a product with good uniformity and excellent performance can be produced.

[0041] Reference Figures 1-3 As shown, a horizontal vibration assembly for working yarn spreading rollers includes a main body 100. Inside the main body 100, from left to right, are arranged yarn spreading rollers 200, 201, 302, 403, 504, 605, 706, 807, 908, and 10029. The two side walls of the main body 100 are provided with sliding grooves 101, 202, 3103, and 4104 from left to right. The rotating shafts at both ends of yarn spreading roller 200 are slidably engaged with sliding groove 101; the rotating shafts at both ends of yarn spreading roller 504 are slidably engaged with sliding groove 202; the rotating shafts at both ends of yarn spreading roller 807 are slidably engaged with sliding groove 303; and the rotating shafts at both ends of yarn spreading roller 908 are slidably engaged with sliding groove 4104. By using spreading rollers 1-200, 2-201, 3-202, 4-203, 5-204, 6-205, 7-206, 8-207, 9-208, and 10-209, dynamic path control of the fiber yarn during the spreading process is achieved. The lifting function allows for flexible adjustment of the spacing between upper and lower layers to accommodate the threading requirements of fiber bundles of different specifications; the vibration function breaks the initial adhesion state of the monofilaments within the fiber bundle through high-frequency rubbing, significantly improving the uniformity of spreading, thereby reducing the surface density deviation of the prepreg and ensuring the stability of mechanical properties.

[0042] In a further preferred embodiment, a lifting rod 105 is fixedly installed on the side wall surface of the main body 100. The top end of the lifting rod 105 is rotatably connected to the end of the rotating shaft on the yarn spreading roller 200. A lifting rod 206 is fixedly connected to the side wall surface of the main body 100. The top end of the lifting rod 206 is rotatably connected to the end of the rotating shaft on the yarn spreading roller 208. By using independent lifting rods 105 and 206 to control the vertical displacement of the yarn spreading roller 200 and the yarn spreading roller 208 respectively, the path interference problem caused by the synchronous adjustment of multiple rollers in traditional yarn spreading devices is solved. This design allows for staged adjustment of the fiber bundle envelope angle, optimizes the yarn spreading tension distribution, and reduces the risk of fiber damage while improving yarn threading efficiency. It is suitable for the large-scale production of high-precision, low-area-density prepregs.

[0043] In a further preferred embodiment, a rack 300 is provided directly below the main body 100. Both ends of the rack 300 are fixedly connected to a sleeve block 301. The top of the sleeve block 301 is fixedly connected to a connecting rod 302. The top of the connecting rod 302 is rotatably connected to the shaft at the end of the yarn spreading roller 203. The end of the yarn spreading roller 203 is slidably inserted into the side wall of the main body 100. A slide rod 303 is slidably inserted into the side of the sleeve block 301. One end of the slide rod 303 is fixedly connected to the side wall of the main body 100. A spring 304 is movably sleeved on the surface of the slide rod 303. One end of the spring 304 is fixedly connected to the sleeve block 301, and the other end of the spring 304 is fixedly connected to the side wall of the main body 100. The horizontal vibration of the spreading roller 203 is driven by a composite mechanism of rack 300, sleeve block 301 and spring 304. The energy storage characteristics of spring 304 are used to achieve adaptive amplitude adjustment. When the fiber bundle load changes, the deformation of spring 304 can buffer the impact load and maintain a constant vibration frequency. The sliding fit between rack 300 and sleeve block 301 ensures the straightness of the vibration trajectory and avoids uneven spreading caused by sway. It is particularly suitable for the precision dispersion of high modulus carbon fibers.

[0044] In a further preferred embodiment, a rack 2 500 is provided directly below the main body 100. Both ends of the rack 2 500 are fixedly connected to a sleeve block 2 501. A hydraulic rod 1 502 is fixedly connected to the top of the sleeve block 2 501. The top of the hydraulic rod 1 502 is rotatably connected to the shaft at the end of the yarn spreading roller 5 204. A sliding rod 2 503 is slidably inserted into the side of the sleeve block 2 501. One end of the sliding rod 2 503 is fixedly connected to the side wall of the main body 100. A spring 2 504 is movably sleeved on the surface of the sliding rod 2 503. One end of the spring 2 504 is fixedly connected to the sleeve block 2 501, and the other end of the spring 1 304 is fixedly connected to the side wall of the main body 100. Innovatively, a dual-drive mode of linkage between the hydraulic rod 1 502 and the rack 2 500 is used to control the yarn spreading roller 5 204. Combined with the crank-slider mechanism of the eccentric wheel 1 306 and the groove frame 1 305, the dual functions of high-frequency reciprocating vibration and axial position fine adjustment of the yarn spreading roller 5 204 are realized. This structure can precisely transmit vibrational energy to the fiber bundle, and together with the reverse rubbing motion of the spreading roller 203, it forms a vortex spreading effect, which greatly improves the lateral elongation of the fiber monofilament.

[0045] In a further preferred embodiment, a slot frame 305 is fixedly connected to the side of rack 300, and a mounting plate 308 is fixedly connected to the bottom of the main body 100. A motor 307 is fixedly mounted on the mounting plate 308, and an eccentric wheel 306 is fixedly connected to the output shaft of the motor 307. The eccentric protrusion on the eccentric wheel 306 is slidably engaged with the slot frame 305. A gear 400 is rotatably connected to the bottom of the main body 100. The gear 400 is located between rack 300 and rack 500 and meshes with both rack 300 and rack 500 respectively. Through the transmission design of gear 400 meshing with rack 300 and rack 500, a phase synchronization mechanism for the two sets of horizontal vibrating rollers is established. When the motor 307 drives the gear to rotate via the eccentric wheel 306, the reciprocating motion of the rack 300 and the rack 500 is converted into differential vibration of the spreading roller, forming a spirally interwoven spreading path, which effectively eliminates the local accumulation defects of the fiber bundle.

[0046] In a further preferred embodiment, a rack 3 600 is provided directly below the main body 100. Both ends of the rack 3 600 are fixedly connected to a sleeve block 3 601. The top of the sleeve block 3 601 is fixedly connected to a connecting rod 2 602. The top of the connecting rod 2 602 is rotatably connected to the shaft at the end of the yarn spreading roller 7 206. The shaft of the yarn spreading roller 7 206 is slidably inserted into the side wall of the main body 100. A slide rod 3 603 is slidably inserted into the side of the sleeve block 3 601. One end of the slide rod 3 603 is fixedly connected to the side wall of the main body 100. A spring 3 604 is movably sleeved on the surface of the slide rod 3 603. One end of the spring 3 604 is fixedly connected to the sleeve block 3 601, and the other end of the spring 3 604 is fixedly connected to the side wall of the main body 100. An independent vibrating yarn-spreading roller group, consisting of yarn-spreading roller 7 (206) and yarn-spreading roller 8 (207), and equipped with hydraulic rod 2 (702), achieves independent high-frequency vibration of the second group of yarn-spreading rollers through the meshing transmission of rack 4 (700) and gear 2 (800). This design can perform secondary untwisting of the initially spread fiber bundle, and is particularly suitable for processing irregular cross-section fibers in multi-axial woven prepregs.

[0047] In a further preferred embodiment, a rack 4 700 is provided directly below the main body 100. Both ends of the rack 4 700 are fixedly connected to a sleeve block 4 701. A hydraulic rod 2 702 is fixedly connected to the top of each sleeve block 4 701. The top of the hydraulic rod 2 702 is rotatably connected to the shaft at the end of the spreading roller 8 207. A slide rod 4 703 is slidably inserted into the side of the sleeve block 4 701. One end of the slide rod 4 703 is fixedly connected to the side wall of the main body 100. A spring 4 704 is movably sleeved on the surface of the slide rod 4 703. One end of the spring 4 704 is fixedly connected to the sleeve block 4 701, and the other end of the spring 4 704 is fixedly connected to the side wall of the main body 100. When the fiber bundle thickness fluctuates, the hydraulic system automatically compensates for pressure changes, maintaining a constant rubbing contact force, avoiding fiber damage caused by hard compression, and significantly extending the service life of the spreading roller.

[0048] In a further preferred embodiment, a slotted frame 705 is fixedly connected to the side of rack four 700, and a mounting plate 708 is fixedly connected to the bottom of the main body 100. A motor 707 is fixedly mounted on the mounting plate 708, and an eccentric wheel 706 is fixedly connected to the output shaft of the motor 707. The eccentric protrusion on the eccentric wheel 706 is slidably engaged with the slotted frame 705. A gear 800 is rotatably connected to the bottom of the main body 100. The gear 800 is located between rack three 600 and rack four 700 and meshes with rack three 600 and rack four 700 respectively. The composite vibration mechanism that drives the slotted frame 705 through the eccentric wheel 706 realizes the multi-dimensional motion coupling of the yarn spreading roller 8 207. The elliptical trajectory vibration generated by this design can effectively remove the sizing agent residue on the surface of the fiber bundle, and online cleaning can be achieved in conjunction with a vacuum adsorption device.
