Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber production equipment, in particular to a tension storage fine yarn frame for a carbon fiber warp knitting machine. Background Art

[0002] In the weaving process of carbon fiber cloth, the tension control of warp yarns is one of the key factors to ensure product quality and production efficiency. With the wide application of carbon fiber materials in the fields of aerospace, automobile manufacturing, sports equipment, etc., the performance requirements for carbon fiber cloth are also increasing day by day, especially for its surface flatness, areal density uniformity and mechanical properties.

[0003] Traditional warp yarn tension control methods mainly rely on fixed tension rollers or simple mechanical adjustment devices. Although these methods can maintain the tension of warp yarns to a certain extent, there are many limitations. The fixed tension roller cannot automatically adjust the tension according to the changes in the warp yarn material, diameter or let-off speed, resulting in easy fluctuations in the warp yarn tension during the weaving process, which in turn affects the flatness of the cloth surface and the uniformity of areal density.

The terms used in the description of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0032] Such as Figures 1 to 6The shown carbon fiber warp knitting machine's storage tension flyer frame includes: a bracket 1, which includes two first bracket frames 11 and second bracket frames 12 arranged in parallel and a cross beam 13 connecting the first bracket frame 11 and the second bracket frame 12; thin rods 2, several of which are evenly spaced along the length direction within the first bracket frame 11, and the thin rods 2 are vertically arranged; yarn guiding seats 3, several of which are evenly arranged along the axial direction of the thin rods 2, and multiple yarn guiding seats 3 in the same row on the thin rods 2 are set at the same height; yarn guiding rods 4, several of which are evenly spaced along the axial direction of the thin rods 2 within the second bracket frame 12, and the yarn guiding rods 4 are provided with yarn guiding holes 41 corresponding one by one to the multiple yarn guiding seats 3 in the same row; among them, a bunching rod 5 is also provided on one side of the second bracket frame 12 above and close to the warp knitting machine's cloth dragging platform 10, and the bunching rod 5 is provided with bunching holes 51 for bunching the yarn passing through the yarn guiding holes 41; a yarn passing assembly 6 is also provided directly below the bunching rod 5 and at the bottom of the warp knitting machine's cloth dragging platform 10.

[0033] The implementation process of the present utility model is that the yarn on the roller 32 of the yarn guiding seat 3 passes through the small hole 321 at one end thereof, then passes through the yarn guiding hole 41 on the yarn guiding rod 4 at the same height as it, and enters the bunching hole 51 on the upper bunching rod 5. Several yarns of the same layer enter the same bunching hole 51. Through the turning of the bunching hole 51, the yarn changes its angle and vertically passes downward through the lower yarn passing assembly 6 and enters the rear warp knitting machine to continue other operations. The beneficial effects of the present utility model are that through the design of the thin rods and the yarn guiding seats, it can ensure that each yarn maintains a stable tension during the transmission process, avoiding the weaving quality problems caused by uneven tension. At the same time, the setting of the bunching rod and the bunching holes further enhances the bunching effect of the yarn; the bottom of the bracket is provided with a mounting frame and a bottom plate, which not only facilitates the installation and fixation of the entire flyer frame, but also is convenient for subsequent maintenance and repair work. In addition, the design of components such as the yarn guiding seat and the bunching rod also takes into account the requirements of easy replacement and adjustment; by adjusting the number and positions of the yarn guiding seats and the yarn guiding holes, this flyer frame can adapt to different specifications and types of yarns, having high flexibility and adaptability.

[0034] In the present utility model, the yarn passing assembly 6 includes a porcelain eye plate 61 and a yarn passing rod 62 arranged below the porcelain eye plate 61; the porcelain eye plate 61 is provided with porcelain eye holes 611 corresponding one by one to the bunching holes 51. The porcelain eye holes 611 on the porcelain eye plate 61 correspond one by one to the bunching holes 51, ensuring that the yarn can accurately and orderly pass through each porcelain eye hole, avoiding the intertwining and chaos of the yarn, and improving the accuracy and efficiency of yarn processing; the setting of the yarn passing rod 62 further provides stable support and guidance for the yarn, enabling the yarn to maintain a straight movement during the transmission process and reducing the bending and wear of the yarn. The material of the porcelain eye plate 61 usually has a smooth surface, which helps to reduce the friction of the yarn when passing through the porcelain eye holes, thereby reducing the risk of the yarn fuzzing and breaking.

[0035] In the present utility model, the number of the bunching holes 51 is less than that of the yarn guiding holes 41. Through the preliminary dispersion of the yarn guiding holes 41, the yarn can be guided to different areas along a predetermined path; while the bunching holes 51 mean that before the yarn enters the key processing area (such as a warp knitting machine), some of the yarn will be combined and processed, improving the flexibility of yarn management and enabling the yarn to be organized and transmitted orderly according to production requirements; during the yarn transmission process, if the number of yarns is too large and too dense, entanglement is likely to occur, and the reasonable setting of the number of bunching holes can effectively avoid this situation and ensure that the yarn remains smooth and orderly during transmission.

[0036] In the present utility model, the yarn guiding seat 3 includes a base 31 fixed on the thin rod 2 and a roller 32 connected to the base 31; a small hole 321 is further provided at the front end of the roller 32. The base 31 is fixed on the thin rod 2, providing a stable support foundation for the entire yarn guiding seat, ensuring the stable position of the yarn guiding seat in the textile machinery, not prone to shaking or offset, thereby guaranteeing the continuity and stability of yarn transmission; the design of the roller 32 enables the yarn to be wound or transmitted around its surface, which not only facilitates the collection and management of the yarn, but also can adjust the tension and density of the yarn to a certain extent to meet different production requirements; the small hole 321 at the front end of the roller 32 may be used for the introduction, export or adjustment of the yarn. Through the small hole 321, the flow direction and speed of the yarn can be conveniently controlled to ensure that the yarn remains smooth and orderly during transmission.

[0037] As a preference of the above embodiment, the base 31 is composed of two symmetric semi-circular fixing pieces, and connection holes are provided thereon. The two symmetric semi-circular fixing pieces are combined together to form a complete circular or approximately circular base, which can ensure uniform force in all directions of the base, thereby providing stable structural support; the setting of the connection holes enables the base to be firmly fixed on the thin rod or other support structures. By using fasteners such as bolts and nuts to tightly connect the base with the support structure, it can be ensured that the base will not become loose or fall off during the operation of the textile machinery.

[0038] In the present utility model, the bunching rod 5 is fixedly connected to the cross beam 13 through a connecting piece 7 arranged at an obtuse angle. The connecting piece 7 with an obtuse angle design is mainly used to convert the angle of the yarn and increase the tension of the yarn during the yarn transmission process to avoid the situation of yarn shaking during transmission. At the same time, the connecting piece 7 with an obtuse angle design provides a more stable support structure in mechanics; compared with a right-angle or acute-angle connection, the obtuse-angle connection can better disperse and bear the force from the bunching rod 5, reducing the stress concentration phenomenon, thereby enhancing the stability and durability of the entire structure.

[0039] In the present utility model, mounting brackets 8 are provided on both sides of the bottom of the bracket 1. The provision of the mounting brackets 8 provides additional support points for the bracket 1, especially at the positions on both sides of the bottom, which helps to disperse the weight and load borne by the bracket, thereby enhancing the stability and anti-overturning ability of the entire structure. In addition, during the operation of the textile machinery, due to the action of factors such as yarn tension and vibration, the bracket may be subject to certain impact forces. The mounting brackets 8 can effectively reduce the impact of such impact forces on the bracket, prevent the bracket from shaking or tilting, and ensure the stable operation of the textile machinery.

[0040] In the present utility model, a bottom plate 9 is further provided at the bottom of the bracket 1. The bottom plate 9 enhances the stiffness of the bracket. The bottom plate 9 is tightly connected to the bottom of the bracket, forming a more solid overall structure and improving the ability of the bracket to resist deformation and vibration. The bottom plate 9 can also prevent pollutants such as oil stains and dust generated during the operation of the textile machinery from directly contacting the ground, which is beneficial to maintaining the cleanliness and hygiene of the production environment.

[0041] Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
