Description

Technical Field

[0001] This application relates to the field of manufacturing high-performance fiber unidirectional prepregs, and in particular to a high-performance fiber separation limiting device. Background Technology

[0002] High-performance fiber unidirectional prepreg is a composite material composed of high-performance fibers and resins. It has advantages such as high strength, corrosion resistance, lightweight, simple manufacturing process, good formability, and good flame retardancy. Therefore, it is widely used in the manufacturing of various fields.

[0003] As is well known, high-performance fiber unidirectional prepreg is a composite material obtained by first combing and positioning high-performance fiber bundles and then impregnating them with resin. Existing high-performance fiber bundles are generally combed and positioned using positioning combs. However, the space at the root of the teeth of the positioning comb is narrow, sharp, and prone to processing defects. Therefore, during the combing and positioning process, the high-performance fiber bundles passing through the teeth of the positioning comb are prone to excessive friction with the root of the teeth of the positioning comb, resulting in fuzzing, jamming, or even breakage. Furthermore, due to the lack of smoothness, this affects the impregnation and molding of the high-performance fiber bundles with the resin.

[0004] High-performance fibers, especially ceramic fibers and high-modulus carbon fibers, are more prone to breakage.

[0005] Therefore, there is an urgent need for a high-performance fiber separation limiting device that can reduce or even eliminate damage to high-performance fiber bundles to overcome the above-mentioned defects. Summary of the Invention

[0006] The purpose of this application is to provide a high-performance fiber separation limiting device that can reduce or even eliminate damage to high-performance fiber bundles.

[0007] To achieve the above objectives, this application provides a high-performance fiber splitting and limiting device, suitable for splitting and limiting incoming high-performance fiber bundles. The high-performance fiber splitting and limiting device includes a reference platform, a splitting and limiting component for splitting the incoming high-performance fiber bundle, and a supporting and guiding component configured to prevent relative sliding with the incoming high-performance fiber bundle. The splitting and limiting component includes a splitting needle and a splitting needle fixing seat fixedly connected to the reference platform. The splitting needle fixing seat is a strip extending in the left-right direction along the reference platform. The splitting needle is located above the splitting needle fixing seat in the up-down direction along the reference platform. The bottom end of the splitting needle is fixed to the needle, and the top end of the splitting needle extends upward in the up-down direction along the reference platform. The splitting needle has multiple... The components are evenly spaced along the left-right direction of the reference platform. The supporting guide assembly includes a rotating motor and a supporting rod. The supporting rod is parallel to the needle-feeding fixing seat and is correspondingly arranged with respect to the needle-feeding. The supporting rod is located in front of the needle-feeding fixing seat in the front-back direction of the reference platform and is spaced apart from the needle-feeding fixing seat in the front-back direction of the reference platform. The top side of the supporting rod is located above the top side of the needle-feeding fixing seat in the up-down direction of the reference platform. The rotating motor is mounted on the reference platform, and the supporting rod is rotatably mounted on the reference platform. The supporting rod is also connected to the output end of the rotating motor. The rotating motor drives the supporting rod to rotate forward synchronously with the high-performance fiber bundle being delivered in the front-back direction of the reference platform.

[0008] Preferably, the support rod is a hollow round tube.

[0009] Preferably, the support guide assembly further includes two bearing seats mounted on the reference platform, one bearing seat being disposed at one end of the support rod and the other bearing seat being disposed at the other end of the support rod, the support rod being assembled to the bearing seat.

[0010] Preferably, the support guide assembly further includes a reducer, which is mounted between the output end of the rotary motor and the support rod.

[0011] Preferably, the reducer further includes a small gear and a large gear, the small gear being mounted on the output end of the rotating motor, and the large gear being mounted on the support rod and meshing with the small gear.

[0012] Preferably, the needle is a cylindrical steel material with a diameter of 1-2 mm, and the surface of the needle is chrome-plated or polished to a mirror finish.

[0013] Preferably, the surface of the support rod is chrome-plated or polished to a mirror finish.

[0014] Compared with the prior art, in the high-performance fiber separation limiting device of this application embodiment, the separation limiting component includes a separation needle and a separation needle fixing seat fixedly connected to the reference platform. The separation needle fixing seat is a strip extending in the left-right direction of the reference platform. The separation needle is located above the separation needle fixing seat in the up-down direction of the reference platform. The bottom end of the separation needle is fixed to the separation needle, and the top end of the separation needle extends upward in the up-down direction of the reference platform. Multiple separation needles are provided and evenly spaced in the left-right direction of the reference platform. The supporting guide component includes a supporting rod, which is parallel to the separation needle fixing seat and parallel to the separation needle. In this configuration, the support rod is rotatably mounted on the reference platform, allowing the sizing and limiting assembly to size and limit the incoming high-performance fiber bundle, and enabling the support and guiding assembly to smoothly guide and output the sized and limited high-performance fiber bundle from the sizing and limiting assembly. This ensures that the high-performance fiber sizing and limiting device of this embodiment can smoothly and steadily size, limit, and guide the incoming high-performance fiber bundle. Furthermore, since the support and guiding assembly in the high-performance fiber sizing and limiting device of this embodiment includes a rotating... The rotating motor is mounted on the reference platform, and the support rod is also connected to the output end of the rotating motor. The rotating motor drives the support rod and the high-performance fiber bundle being transported to rotate forward synchronously along the front-back direction of the reference platform. This avoids relative sliding between the support rod and the high-performance fiber bundle being transported, thereby preventing frictional fuzzing or even breakage caused by sliding friction between the glass fiber bundle and the support rod. Furthermore, since the support rod is located in front of the needle-spinning fixing seat along the front-back direction of the reference platform and is arranged separately from the needle-spinning fixing seat along the front-back direction of the reference platform, motion interference between the support rod and the needle-spinning fixing seat is avoided. The top side of the support rod is located above the top side of the needle-spinning fixing seat along the vertical direction of the reference platform, preventing the high-performance fiber bundle passing through the top side of the support rod from abutting the needle-spinning fixing seat during forward movement. This avoids frictional fuzzing, jamming, or even breakage caused by mutual friction between the high-performance fiber bundle and the needle-spinning fixing seat. Thus, the high-performance fiber splitting limiting device of this embodiment can reduce or even avoid damage to the high-performance fiber bundle during the splitting and transport process.

[0020] Please see Figure 1-3The high-performance fiber splitting limiting device 1 of this application embodiment includes a reference platform 10, a splitting limiting component 20, and a supporting guide component 30. The splitting limiting component 20 includes a splitting needle 21 and a splitting needle fixing seat 22 fixedly connected to the reference platform 10. The splitting needle fixing seat 22 is strip-shaped, extending in the left-right direction along the reference platform 10. The splitting needle 21 is located above the splitting needle fixing seat 22 in the up-down direction along the reference platform 10. The bottom end of the splitting needle 21 is fixed to the splitting needle 21, and the top end of the splitting needle 21 extends upward in the up-down direction along the reference platform 10. Multiple splitting needles 21 are provided and evenly spaced in the left-right direction along the reference platform 10 for splitting the high-performance fiber bundles that are transported. The supporting guide component 30 includes a rotating motor 31 and a supporting rod 32. The supporting rod 32 is parallel to the splitting needle fixing seat 22 and is correspondingly arranged with respect to the splitting needle 21. The supporting rod 32 is located in front of the splitting needle fixing seat 22 in the front-back direction along the reference platform 10 and is parallel to the splitting needle fixing seat 22 in the front-back direction along the reference platform 10. The reference platform 10 is arranged in a front-to-back direction with the top side of the support rod 32 located above the top side of the needle fixing seat 22 along the vertical direction of the reference platform 10. The rotary motor 31 is mounted on the reference platform 10, and the support rod 32 is rotatably mounted on the reference platform 10. The support rod 32 is also connected to the output end of the rotary motor 31. The rotary motor 31 drives the support rod 32 to rotate forward synchronously with the high-performance fiber bundle being transported along the front-to-back direction of the reference platform 10. This reduces friction between the support guide assembly 30 and the high-performance fiber bundle being transported, and prevents the high-performance fiber bundle passing through the top side of the support rod 32 from passing through the narrow space formed by the needle fixing seat 22 and the bottom end of the needle 21 during its forward movement. This avoids friction rubbing, jamming, or even breakage caused by the high-performance fiber bundle rubbing against the needle fixing seat 22 and the bottom end of the needle 21, thus preventing significant damage to the high-performance fiber bundle during the separation and limiting process. More specifically as follows:

[0021] Preferably, the support rod 32 is a hollow round tube to reduce its weight.

[0022] like Figure 1-3 As shown, the support guide assembly 30 also includes two bearing seats 33 mounted on the reference platform 10. One bearing seat 33 is located at one end of the support rod 32, and the other bearing seat 33 is located at the other end of the support rod 32. The support rod 32 is assembled on the bearing seat 33.

[0023] like Figure 1-3 As shown, the support guide assembly 30 also includes a reducer 34, which is mounted between the output end of the rotating motor 31 and the support rod 32 to reduce speed and increase torque, thereby better driving the support rod 32 to rotate synchronously with the high-performance fiber bundle.

[0024] like Figure 1As shown, the reducer 34 also includes a small gear 341 and a large gear 342. The small gear 341 is mounted on the output end of the rotating motor 31, and the large gear 342 is mounted on the support rod 32 and meshes with the small gear 341, so that the reducer 34 has a reasonable and compact structure.

[0025] Preferably, the sparse needle 21 is a cylindrical steel material with a diameter of 1-2 mm. The surface of the sparse needle 21 is chrome-plated or polished to a mirror finish in order to separate high-performance fiber bundles and reduce or even avoid damage to the high-performance fiber bundles.

[0026] Preferably, the surface of the support rod 32 is chrome-plated or polished to a mirror finish to reduce or even avoid damage to the high-performance fiber bundle.

[0027] Compared with the prior art, in the high-performance fiber separation limiting device 1 of this application embodiment, the separation limiting component 20 includes a separation needle 21 and a separation needle fixing seat 22 fixedly connected to the reference platform 10. The separation needle fixing seat 22 is strip-shaped and extends along the left-right direction of the reference platform 10. The separation needle 21 is located above the separation needle fixing seat 22 along the up-down direction of the reference platform 10. The bottom end of the separation needle 21 is fixed to the separation needle 21, and the top end of the separation needle 21 extends upward along the up-down direction of the reference platform 10. Multiple separation needles 21 are provided and evenly spaced along the left-right direction of the reference platform 10. The supporting guide component 30 includes a supporting rod 32, which is parallel to the separation needle 21. The needle fixing seat 22 is correspondingly arranged with the sparse needle 21, and the support rod 32 is rotatably mounted on the reference platform 10, so that the sparse limiting component 20 can sparse and limit the high-performance fiber bundle that is fed in, and the support guide component 30 can smoothly guide and output the high-performance fiber bundle that has been sparse and limited by the sparse limiting component 20. Thus, the high-performance fiber sparse limiting device 1 of this application embodiment can smoothly and steadily sparse, limit and guide the high-performance fiber bundle that is fed in. In addition, since the support guide component 30 includes a rotary motor 31 in the high-performance fiber sparse limiting device 1 of this application embodiment, The rotating motor 31 is mounted on the reference platform 10, and the support rod 32 is also connected to the output end of the rotating motor 31. The rotating motor 31 drives the support rod 32 to rotate forward synchronously with the high-performance fiber bundle being transported along the front-back direction of the reference platform 10. This avoids relative sliding between the support rod 32 and the high-performance fiber bundle being transported, thereby preventing frictional fuzzing or even breakage caused by sliding friction between the glass fiber bundle and the support rod 32. Furthermore, since the support rod 32 is located in front of the needle-retaining seat 22 along the front-back direction of the reference platform 10 and is arranged separately from the needle-retaining seat 22 along the front-back direction of the reference platform 10, it avoids frictional fuzzing or even breakage caused by sliding friction between the support rod 32 and the high-performance fiber bundle being transported. Movement interference occurs between the needle fixing seats 22; the top side of the support rod 32 is located above the top side of the needle fixing seat 22 along the vertical direction of the reference platform 10, which can prevent the high-performance fiber bundle passing through the top side of the support rod 32 from passing through the narrow space formed by the bottom end of the needle fixing seat 22 and the needle 21 during forward movement, thereby avoiding friction fuzzing, jamming or even breakage caused by mutual friction between the high-performance fiber bundle and the bottom end of the needle fixing seat 22 and the needle 21; thus, the high-performance fiber separation limiting device 1 of this application embodiment can avoid damage to the high-performance fiber bundle during the separation and transmission process.

[0028] It should be noted that in the attached diagram, arrow A points downward along the vertical direction of the reference base 10, and vice versa. Arrow B points to the right along the horizontal direction of the reference base 10, and vice versa. Arrow C points forward along the front-back direction of the reference base 10, and vice versa. The directions of arrow A, arrow B, and arrow C are perpendicular to each other, but this is not a limitation.

[0029] The above-disclosed examples are merely preferred embodiments of this application, intended to facilitate understanding and implementation by those skilled in the art. They should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with the scope of this application are still within the scope of this application.
