Description

Technical Field

[0001] This application belongs to the technical field of cable production equipment, and more specifically, it relates to a uniform distribution equipment for aramid fiber materials used in cable production. Background Technology

[0002] During use, cables typically require aramid fiber filling to meet tensile strength requirements. Due to variations in construction environments, the arrangement of aramid fibers can differ. For example, sometimes the aramid fiber material is not layered around the core, but rather formed into multiple strands and distributed around the core, achieving the same improved tensile strength. For instance, the high-strength, corrosion-resistant aluminum alloy core low-voltage power cable disclosed in utility model patent CN220189308U features multiple aramid fiber reinforcing cores distributed around the conductor.

[0003] In actual production, depending on the tensile strength, sometimes multiple aramid fibers are not tightly wrapped around the outside of the core as in the aforementioned patented solution. Instead, a smaller number of aramid fibers are arranged around the core with some gaps between them. Because adjacent aramid fibers are not tightly bonded, uneven distribution of the aramid fibers during production can lead to poor tensile stability, uneven coverage, and even core misalignment in the cable. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a uniform distribution device for aramid fiber materials in cable production, which can evenly distribute aramid fiber materials around the wire core during the production process, ensuring uniform strength distribution of the cable.

[0005] To achieve the above objectives, the technical solution of this application provides a uniform distribution device for aramid fiber materials used in cable production, including a base. A straightening plate, a wiring bracket, and several wire feeding posts are fixedly installed on the top of the base. The wire feeding posts are used to hold aramid spools. The straightening plate has wire core perforations and several aramid wire holes evenly distributed around the wire core perforations. The wiring bracket is provided with several support ends distributed around the extension direction of the wire core perforations. Each support end corresponds to one of the aramid wire holes, and each support end is equipped with a tension wheel.

[0006] The core perforation is used to thread the aramid fiber. After the aramid fiber from the aramid bobbin is drawn out, it passes around the tension wheel and then through the corresponding aramid fiber hole, so that the aramid fiber and the core can be extruded by the extruder. The combined action of the extruder and the tension wheel ensures the aramid fiber is taut. Due to the corrective effect of the straightening plate on the position of the aramid fiber, and the orientation correction effect of the support end on the aramid fiber, it is ensured that the aramid fiber output from the straightening plate is evenly distributed around the core, ensuring uniform strength distribution of the processed cable.

[0007] Optionally, the cabling bracket includes a mounting body and a U-shaped support body. The bottom end of the support body is fixedly connected to the base via the mounting body, and both top ends of the support body serve as support ends. The internal cutouts of the support body are positioned opposite to the wire core perforations. The internal space of the U-shaped support body can accommodate the wire cores, and the support ends can accommodate the distribution of tension wheel positions.

[0008] Optionally, there are several support bodies, and the height of the support ends of these support bodies gradually increases in the direction away from the straightening plate. Since the U-shaped support body only has two support ends, by setting several support bodies, more support ends can be provided to accommodate the arrangement of a larger number of aramid fibers. The height of the support ends gradually increases in the direction away from the straightening plate, so the support bodies closer to the straightening plate will not obstruct the aramid fibers drawn out from the support bodies farther away from the straightening plate.

[0009] Optionally, the mounting body is a mounting rod, the bottom end of which is fixedly connected to the base, and the top end of which is connected to the bottom middle part of the support body, thereby connecting the support body and the base.

[0010] Optionally, several pay-off posts are distributed in two groups on both sides of the mounting rod, with each pay-off post corresponding to a support end, and the pay-off posts located at the bottom of the corresponding support end. Since the mounting rod is a thin rod structure, the bottom of the U-shaped support body has space to accommodate the pay-off posts. The pay-off posts can be placed directly below the corresponding support end, reducing space occupation while facilitating the pay-off of aramid fibers.

[0011] Optionally, the system also includes fastening bolts. A vertical guide rod is provided at the top of the base, and the straightening plate has a guide sleeve that slides onto the outside of the vertical guide rod. The fastening bolts screw into the guide sleeve from the outside and abut against the vertical guide rod. By sliding the guide sleeve along the vertical guide rod, the relative position of the straightening plate and the wiring bracket can be adjusted to achieve orientation alignment. After orientation alignment, the position of the straightening plate is fixed by the fastening bolts.

[0012] Optionally, the base is equipped with casters at the bottom to facilitate overall movement of the equipment and reduce vibration during movement.

[0013] The advantages of the technical solution in this application compared to the prior art are as follows:

[0014] The core perforation is used to thread the aramid fiber. After the aramid fiber from the aramid bobbin is drawn out, it passes around the tension wheel and through the corresponding aramid fiber hole, so that the aramid fiber and the core can be extruded by the extruder. Due to the corrective effect of the straightening plate on the position of the aramid fiber, and the orientation correction effect of the support end on the aramid fiber, it can be ensured that the aramid fiber output from the straightening plate is evenly distributed around the core, ensuring uniform strength distribution of the processed cable. This equipment can be integrated into the entire cable processing production line as part of the aramid fiber even distribution. Attached Figure Description

Detailed Implementation

[0018] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0019] Example:

[0020] This embodiment provides a uniform distribution device for aramid fiber materials used in cable production, based on... Figure 1 As shown, the system includes a base 1, on the top of which a straightening plate 2, a wiring bracket 3, and several wire feeding posts 4 are fixedly mounted. The wire feeding posts 4 are used to mount aramid spools 5, which rotate on the posts 4 to feed the wire. In this embodiment, the straightening plate 2 has a disc-shaped structure, with wire core perforations 200 and several aramid wire holes 7 evenly distributed around the perforations 200. The wiring bracket 3 has several support ends 8 distributed around the extension direction of the perforations 200, each support end 8 corresponding to one of the aramid wire holes 7, and each support end 8 is equipped with a tension wheel 9.

[0021] In this embodiment, there are four support ends 8 and four pay-off posts 4. Four sets of aramid spools 5 are respectively sleeved on the outside of the pay-off posts 4. After the aramid fibers 100 are drawn out from the aramid spools 5, they pass around the four tension wheels 9 and through the corresponding aramid wire holes 7 on the straightening plate 2. The wire core holes 200 are used to pass through the wire cores 200. After the wire cores 200 and aramid fibers 100 pass through the straightening plate 2, they are squeezed by the subsequent extruder to form a cable wrapped with four aramid fibers 100. During the production process, the tension wheels 9 and the extruder in the subsequent process can ensure the tension of the aramid fibers 100. Due to the corrective effect of the straightening plate 2 on the position of the aramid fibers 100, it can be ensured that the aramid fibers 100 output from the straightening plate 2 can be evenly distributed around the wire cores 200, ensuring the uniform strength distribution of the processed cable. The aramid fiber material uniform distribution equipment for cable production in this embodiment can be integrated into the entire cable processing production line and used as part of the uniformly distributed aramid fiber 100.

[0022] Of course, in other embodiments, the number of support end 8, wire release post 4 and corresponding through aramid wire hole 7 can be set to six or eight as needed, so as to process a cable wrapped with six or eight aramid fibers 100.

[0023] Furthermore, the wiring bracket 3 includes a mounting body 10 and a U-shaped support body 11. The bottom end of the support body 11 is fixedly connected to the base 1 via the mounting body 10, and both top ends of the support body 11 serve as support ends 8. The internal hollow portion of the support body 11 is positioned opposite to the wire core through-hole 200. In this case, the internal space of the U-shaped support body 11 can avoid the wire core 200, and the support ends 8 can accommodate the distribution of the tension wheel 9.

[0024] Furthermore, since each support body 11 has only two support ends 8, to accommodate a larger number of aramid fibers 100, there are several support bodies 11, and the height of the support ends 8 of these support bodies 11 gradually increases in the direction away from the straightening plate 2. For the four aramid fibers 100 in this embodiment, two support bodies 11 are required, and the corresponding number of pay-off posts 4 is four. For a larger number of aramid fibers 100, the number of support bodies 11 and pay-off posts 4 increases accordingly. The support ends 8 of different heights are used to achieve the arrangement of the support ends 8 of different support bodies 11 around the extension direction of the wire core perforation 200. The height of the support ends 8 gradually increases in the direction away from the straightening plate 2, so that the support bodies 11 closer to the straightening plate 2 will not obstruct the aramid fibers 100 drawn out from the support bodies 11 away from the straightening plate 2, thus avoiding the aramid fibers 100 from tangling together.

[0025] Furthermore, the mounting body 10 is a mounting rod, with its bottom end fixedly connected to the base 1 and its top end connected to the bottom middle of the support body 11, thus connecting the support body 11 to the base 1. Simultaneously, several wire-feeding posts 4 are distributed in two groups on both sides of the mounting rod, with each wire-feeding post 4 corresponding to a support end 8, and the wire-feeding post 4 located at the bottom of the corresponding support end 8. For example, in this embodiment, four wire-feeding posts 4 are distributed in pairs on both sides of the mounting rod. For six or eight wire-feeding posts 4, they are similarly evenly divided into two groups on both sides of the mounting rod. Because the mounting rod is a thin rod structure, the bottom of the U-shaped support body 11 has space to accommodate the wire-feeding posts 4. The wire-feeding posts 4 can be positioned directly below the corresponding support end 8, reducing space occupation while also facilitating the direct extraction of aramid fibers 100 from the aramid spool 5 to the support end 8.

[0026] Furthermore, it also includes a fastening bolt 12. A vertical guide rod 13 is provided on the top of the base 1, and the straightening plate 2 is provided with a guide sleeve 14 that slides on the outside of the vertical guide rod 13. The fastening bolt 12 screws in from the outside, passes through the guide sleeve 14, and abuts against the vertical guide rod 13. By sliding the guide sleeve 14 along the vertical guide rod 13, the relative position of the straightening plate 2 and the wiring bracket 3 can be adjusted to achieve orientation alignment. After orientation alignment, the position of the straightening plate 2 is fixed by the fastening bolt 12.

[0027] In this embodiment, a caster wheel 15 is provided at the bottom of the base 1 to facilitate overall movement of the equipment and reduce vibration during movement.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
