Description

Technical Field

[0001] This utility model relates to the field of yarn separation technology, and in particular to an auxiliary tool for separating carbon fiber warp yarns. Background Technology

[0002] Carbon fiber is a new type of fiber material made by stacking organic fibers along the fiber axis and then undergoing carbonization and graphitization. It has advantages such as being lightweight, corrosion-resistant, high-temperature resistant, high-strength, and high-modulus. Due to its excellent properties, it has been widely used in aerospace, automotive industry, energy equipment and other fields.

[0003] Carbon fiber can be woven into fabrics or woven materials. Three-dimensional weaving technology is used to weave yarns formed by mixing fiber and resin under heat and pressure, resulting in large-size, high-precision carbon fiber composite materials. These materials offer excellent performance in improving interlaminar strength, damage tolerance, and thermal stress loss. However, during the weaving process using a weaving machine, the large space required for weaving necessitates multiple working platforms. To ensure the quality of the woven product, personnel on the first working platform must sequentially pass the carbon fiber yarns to the second working platform, and then arrange and organize them to ensure the separation of each warp yarn column, facilitating subsequent weaving operations. This method is not only time-consuming and labor-intensive, but manual operation also makes it difficult to guarantee production efficiency, thus affecting the output and quality of the woven material.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background technology of this utility model, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] like Figures 1 to 5 The auxiliary tooling for separating carbon fiber warp yarns shown is set at the second working platform 1a of the braiding machine 1. It includes a grid frame 3 and several grid bars 4. The inner side of the grid frame 3 is hollow to form a yarn separating space 3a. Several grid bars 4 are arranged sequentially in the yarn separating space 3a along the length direction of the grid frame 3.

[0029] Among them, several grid bars 4 are arranged in parallel to each other, and a layer gap 3b is formed between adjacent grid bars 4. Each layer of warp yarns is arranged in the corresponding layer gap 3b.

[0030] This invention, by setting a grid frame 3 and grid bars 4 on the second-layer working platform 1a of the braiding machine 1, can automatically separate and arrange the warp yarns, reducing the step of manually passing the warp yarns layer by layer, thereby saving time, reducing labor costs and improving production efficiency; the warp yarns can be automatically and accurately arranged in the corresponding layer gaps 3b according to the predetermined positions, which helps to reduce damage during the weaving process and improves the accuracy and quality of the woven fabric 2b.

[0031] The grid frame 3 provides a stable support platform for the grid bars 4, which facilitates the support and separation of warp yarns. The hollow design provides installation space while reducing the overall weight, making it easier to operate and maintain. The layer gap 3b between adjacent grid bars 4 provides a precise arrangement position for the warp yarns, ensuring the uniform distribution of the warp yarns, guaranteeing the accurate arrangement effect, facilitating subsequent weaving work, and also improving the quality of the woven fabric 2b.

[0032] Based on the above embodiments, the size of the interlayer gap 3b can be adjusted, and the size of the interlayer gap 3b between adjacent layers is the same. The size of the interlayer gap 3b can be achieved by adding, subtracting or adjusting the position of the grid bars 4. By adjusting the size of the interlayer gap 3b, it is possible to adapt to the production of carbon fiber woven fabrics 2b with different thicknesses and performance requirements, thereby increasing the flexibility and adaptability of the process.

[0033] Based on the above embodiments, the grid frame 3 is rectangular, including a pair of support plates 31 and a pair of connecting plates 32. The two support plates 31 are arranged parallel to each other, and the two connecting plates 32 are arranged parallel to each other. The rectangular grid frame 3 provides a stable support structure. The parallel support plates 31 and connecting plates 32 can evenly distribute the force, enhancing the stability and durability of the entire frame. It is also easy to assemble and operate, reducing the complexity of operation.

[0034] Based on the above embodiments, the axis of the grid bar 4 is arranged parallel to the connecting plate 32, and both ends are detachably connected to the support plates 31 on both sides. When it is necessary to replace the damaged grid bar 4 or perform maintenance, it can be quickly disassembled and reinstalled, reducing maintenance time and cost. It is also convenient to adjust the position and number of grid bars 4 according to specific production needs, improving the flexibility and adaptability of the tooling. Furthermore, the parallel arrangement of the grid bar 4 and the connecting plate 32 helps to evenly distribute the tension of the warp yarns, reduce structural deformation caused by uneven stress, and enhance the stability of the entire grid frame 3.

[0035] Based on the above embodiment, several pairs of assembly holes 31a are symmetrically arranged on the two support plates 31 along the length direction. The two ends of the grid rod 4 are set in any one of the assembly holes 31a, and the two end faces of the grid rod 4 protrude from the side of the grid frame 3 away from the yarn separating space 3a. By setting the assembly holes 31a on the support plate 31, the grid rod 4 can be accurately positioned and fixed, ensuring that the spacing between the grid rods 4 is uniform, thereby ensuring the consistency of the yarn separating space 3a. It also allows the grid rod 4 to be quickly assembled and adjusted, improving the assembly efficiency of the tooling. Furthermore, the design of the two ends of the grid rod 4 protruding from the assembly holes 31a increases the contact area between the grid rod 4 and the support plate 31, improving the stability of the connection and the overall strength of the structure.

[0036] Based on the above embodiments, the number of mounting holes 31a on each support plate 31 is greater than or equal to the number of grid bars 4; the increase in the number of mounting holes 31a provides more installation options, and the installation position of grid bars 4 can be flexibly selected according to specific production needs and warp yarn arrangement requirements; and when the number of grid bars 4 changes, it is not necessary to replace the support plate 31, reducing material waste and production costs.

[0037] Based on the above embodiments, the cross-sectional shape of the assembly hole 31a is the same as that of the grid bar 4, and the grid bar 4 and the assembly hole 31a are fitted with a clearance fit; this ensures a precise fit between the grid bar 4 and the assembly hole 31a, improving the fit accuracy of the overall structure; it reduces the error during the installation of the grid bar 4, ensuring the accurate position of the grid bar 4 on the support plate 31, which is beneficial for maintaining the uniform distribution of warp yarns during the weaving process; the clearance fit facilitates the assembly of the grid bar 4 while helping to reduce the wear between the grid bar 4 and the assembly hole 31a during assembly and use, thus extending the service life of the grid bar 4.

[0038] Based on the above embodiments, the cross-sectional shape of the assembly hole 31a is circular or polygonal; it can be adapted to the cross-sectional shape of the grid bar 4. The circular assembly hole 31a can reduce the wear and tear of the grid bar 4 during assembly and disassembly; the polygonal cross-section provides higher structural strength in different directions, which helps to enhance the overall stability of the grid frame 3 after the grid bar 4 is assembled.

[0039] Based on the above embodiment, a limiting hole 41 is provided on the outer axial surface of the grid rod 4 located outside the grid frame 3, and the axis of the limiting hole 41 is arranged along the radial direction of the grid rod 4; a locking member 5 is provided in each limiting hole 41, and the locking member 5 is detachably connected to the grid rod 4; the use of the locking member 5 can ensure that the grid rod 4 is securely locked in the limiting hole 41, preventing the grid rod 4 from shifting or falling off due to vibration or external force, thus improving the reliability of the entire structure; and the detachable connection between the grid rod 4 and the locking member 5 allows the grid rod 4 to be quickly and safely disassembled and replaced when needed, reducing the safety risks during operation.

[0040] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
