Description

Technical Field

[0001] This utility model relates to the field of yarn spreading roller technology, specifically a vertical 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 continuous improvement of material performance requirements due to industrial upgrading, the demand for low areal density prepregs is growing.

[0003] Existing carbon fiber composite materials are produced by processing raw materials through a yarn spreading device and then subjecting the raw materials to a series of subsequent processing steps.

[0004] The yarn spreading device, composed of several sets of spreading rollers, is used to spread fiber yarns evenly, control tension, guide direction, and comb the fibers. However, the positions of the spreading rollers in existing spreading devices are relatively fixed, which can easily lead to localized dense and sparse areas during the spreading process. This results in inconsistent fabric density and uneven thickness. Furthermore, the rollers are prone to tangling and knotting, and the relatively large and uneven friction between the yarn and the spreading rollers increases the wear on both the yarn and the rollers, affecting the spreading effect and the combing effect of the fibers.

[0005] Therefore, it is necessary to propose a vertical vibration component for the operation of the yarn spreading roller. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a vertical vibration component for the operation of a yarn spreading roller, which has the advantages of effectively spreading yarn evenly, reducing wear, thereby improving production efficiency and enhancing fiber combing effect, and solves the problems mentioned in the background technology.

[0007] This utility model provides the following technical solution: a vertical vibration assembly for working a yarn spreading roller, comprising a supporting body, characterized in that:

[0008] The supporting body has, from left to right, a yarn spreading roller 1, a yarn spreading roller 2, a yarn spreading roller 3, a yarn spreading roller 4, a yarn spreading roller 5, a yarn spreading roller 6, a yarn spreading roller 7, a yarn spreading roller 8, a yarn spreading roller 9, and a yarn spreading roller 10. The yarn spreading roller 1 and the yarn spreading roller 9 are connected to the yarn spreading roller 1 by a sliding groove 1, and the yarn spreading roller 3 and the yarn spreading roller 6 are connected to the supporting body by a sliding groove 2.

[0009] The two ends of the yarn spreading rollers three and six extend into the interior of the sliding groove two, and the outer surfaces of the extended ends of the yarn spreading rollers three and six are fixedly connected with the sleeve ring two. The lower side of the supporting body is fixedly connected with an L-shaped mounting block. A cylinder is mounted on the upper surface of the L-shaped mounting block. A bearing plate two is mounted on the output end of the cylinder. A motor is mounted on the upper surface of the bearing plate two. A cam is fixedly connected to the output shaft of the motor. A connecting shaft two is fixedly connected to the lower outer end of the sleeve ring two. A connecting shaft one is fixedly connected to the upper side of one side of the cam. A connecting rod is rotatably connected to the outer surfaces of the connecting shaft two and the connecting shaft one.

[0010] Preferably, slide rails are fixedly connected to both ends of the outer side of the second slide groove, and sliders are fixedly connected to both sides of the outer surface of the second sleeve ring, with the outer surface of the sliders slidably connected to the inside of the slide rails.

[0011] Preferably, limit rods are fixedly connected to both sides of the upper surface of the L-shaped mounting block, and the outer surface of the limit rods is movably connected to the interior of the bearing plate.

[0012] Preferably, a bearing plate is provided at the lower outer end of the slide groove, and the side of the bearing plate is fixedly connected to the side of the bearing body. The two ends of the yarn spreading roller 1 and the yarn spreading roller 9 extend out of the interior of the slide groove, and a sleeve ring is fixedly connected to the outer surface of the extended ends of the yarn spreading roller 1 and the yarn spreading roller 9.

[0013] Preferably, an electric telescopic rod is installed on the upper surface of the bearing plate, and the output shaft of the electric telescopic rod is fixedly connected to the lower side of the outer surface of the sleeve ring.

[0014] Preferably, both ends of the yarn spreading rollers 2, 4, 5, 7, 8 and 10 are fixedly connected to the inner sides of the supporting body.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This type of yarn spreading roller uses a vertical vibration assembly. A cylinder drives spreading rollers three and six to move up and down. Once at the designated position, a motor activates the rollers. The cam and connecting ring two, connected by a connecting shaft two, a connecting rod, and a connecting shaft one, achieve crank motion, enabling spreading rollers three and six to vibrate at high frequency. This structure effectively distributes the yarn more evenly on the spreading rollers. The small impact force generated by the vibration prevents localized yarn accumulation or tangling, maintaining good yarn spread during the spreading process. This improves subsequent processing quality, reduces yarn wear, lowers the risk of yarn breakage, and enhances yarn quality and production efficiency. It further reduces stalling and jamming during the spreading process, making the entire spreading process smoother and resulting in more orderly fiber arrangement. It also removes impurities and tangles from the fibers, improving fiber quality and spinnability. Attached Figure Description

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] Please see Figure 1 , Figure 2 and Figure 3 A vertical vibration assembly for working a yarn spreading roller includes a supporting body 1:

[0030] The supporting body 1 has, from left to right, a yarn spreading roller 110, a yarn spreading roller 2 120, a yarn spreading roller 3 130, a yarn spreading roller 4 140, a yarn spreading roller 5 150, a yarn spreading roller 6 160, a yarn spreading roller 7 170, a yarn spreading roller 8 180, a yarn spreading roller 9 190, and a yarn spreading roller 10 2. The yarn spreading roller 110 and the yarn spreading roller 9 190 are connected to the yarn spreading roller 110 by a sliding groove 330. The yarn spreading roller 3 130 and the yarn spreading roller 6 160 are connected to the supporting body 1 by a sliding groove 430.

[0031] The two ends of the yarn spreading rollers 130 and 160 extend into the interior of the groove 430. The outer surfaces of the extended ends of the yarn spreading rollers 130 and 160 are fixedly connected to the sleeve ring 450. The lower side of the bearing body 1 is fixedly connected to the L-shaped mounting block 4. The upper surface of the L-shaped mounting block 4 is equipped with a cylinder 410. The output end of the cylinder 410 is equipped with a bearing plate 420. The upper surface of the bearing plate 420 is equipped with a motor 421. The output shaft of the motor 421 is fixedly connected to a cam 422. The lower outer side of the sleeve ring 450 is fixedly connected to the connecting shaft 451. The upper side of the cam 422 is fixedly connected to the connecting shaft 423. The outer surfaces of the connecting shaft 451 and the connecting shaft 423 are rotatably connected to the connecting rod 470.

[0032] The operation of cylinder 410 can drive the yarn spreading roller 3 130 and yarn spreading roller 6 160 to move up and down. When they move to the designated position, the motor 421 will work. Since the cam 422 and the sleeve ring 2 450 are connected by connecting shaft 2 451, connecting rod 470 and connecting shaft 1 423 to achieve crank motion, the yarn spreading roller 3 130 and yarn spreading roller 6 160 can achieve high-frequency vertical vibration.

[0033] As a preferred technical solution of this utility model, slide rails 440 are fixedly connected to both ends of the outer side of the slide groove 430, and sliders 452 are fixedly connected to both sides of the outer surface of the sleeve ring 450. The outer surface of the sliders 452 is slidably connected to the inside of the slide rails 440.

[0034] The sliding engagement of slide rail 440 and slider 452 ensures the stability of yarn spreading roller 3 130 and yarn spreading roller 6 160 during high-frequency vertical vibration, preventing positional shifts.

[0035] As a preferred technical solution of this utility model, the upper surface of the L-shaped mounting block 4 is fixedly connected to both sides of the limiting rod 460, and the outer surface of the limiting rod 460 is movably connected to the interior of the bearing plate 420.

[0036] When the cylinder 410 drives the second support plate 420, which is equipped with a motor 421, to move up and down, the second support plate 420 moves up and down synchronously on the outer surface of the limit rod 460 to ensure stability during movement.

[0037] As a preferred technical solution of this utility model, a bearing plate 3 is provided at the lower outer end of the slide groove 330, and the side of the bearing plate 3 is fixedly connected to the side of the bearing body 1. The two ends of the yarn spreading roller 110 and the yarn spreading roller 9190 extend out of the interior of the slide groove 330, and a sleeve ring 320 is fixedly connected to the outer surface of the extended end of the yarn spreading roller 110 and the yarn spreading roller 9190. An electric telescopic rod 310 is installed on the upper surface of the bearing plate 3, and the output shaft of the electric telescopic rod 310 is fixedly connected to the lower side of the outer surface of the sleeve ring 320.

[0038] The electric telescopic rod 310 operates to drive the yarn spreading rollers 110 and 190 to move up and down, providing pre-tension force for the entire system and ensuring the quality of yarn spreading.

[0039] As a preferred technical solution of this utility model, both ends of yarn spreading roller 2 120, yarn spreading roller 4 140, yarn spreading roller 5 150, yarn spreading roller 7 170, yarn spreading roller 8 180 and yarn spreading roller 10 2 are fixedly connected to the inner sides of the supporting body 1.

[0040] During the spreading process, the fiber yarn passes through spreading rollers 110, 120, 130, 140, 150, 160, 170, 180, 190 and 10 in an S-shape.
