[0035] The upper motor 2 is a variable frequency motor.

[0036] like Figure 4 As shown, the rope splitter 7 consists of a frustum, a connecting rod and a sliding sleeve. The axis of the frustum is in the same straight line as the axis of the large gear 3.

[0040] The method for using the large-diameter carbon fiber rope braiding device of the present invention comprises the following steps:

[0041] 1) 4 to 8 strands of fine carbon fiber rope 6 are drawn out from the corresponding winding shaft, passed through the corresponding upper tension shaft 5, passed around the corresponding rope hook, passed through the corresponding rope groove on the rope splitter 7, and then passed out from the rope twisting shaft 13, and fixed on the rope collection hook of the rope collection shaft 14;

[0042] 2) Start the tightening motor 2, the rope-twisting motor 12, and the rope-collecting motor 15; the tightening motor 2 drives the large gear 3 to rotate, which in turn drives the small gears 4 to rotate; the tightening shaft 5 rotates synchronously with the small gear 3, and the spiral groove of the tightening shaft 5 is used to tighten each strand of the fine carbon fiber rope 6; the tightened multiple strands of fine carbon fiber rope 6 are automatically twisted together after passing through the rope splitter 7 to form a thick carbon fiber rope 10; at the same time, the rope-twisting motor 12 drives the rope-twisting shaft 13 to rotate, and the rope-collecting motor 15 drives the rope-collecting shaft 14 to rotate; the thick carbon fiber rope 10 moves forward under the guidance of the spiral groove on the rope-twisting shaft 13 and is wound around the rope-collecting shaft 14;

[0043] 3) The force generated during the twisting of the thin carbon fiber rope 6 causes the rope splitter 7 to slowly move along the slide rail 8 toward the rope twisting assembly. When the rope splitter 7 moves to the extreme position close to the upper tension assembly, the corresponding proximity switch 9 is triggered, and the control system controls the rope twisting motor 12 to increase the speed, causing the rope splitter 7 to move in the opposite direction. When the rope splitter 7 moves to the extreme position close to the rope twisting assembly, the corresponding proximity switch 9 is triggered, and the control system controls the rope collection motor 15 to increase the speed. Through the two proximity switches 9, the rope twisting and rope collection actions are balanced, thereby ensuring the tightness and uniformity of the thick carbon fiber rope 10.

[0044] 4) After the coarse carbon fiber rope 10 is woven, the tails of the twisted ends of each strand of the fine carbon fiber rope 6 are knotted to prevent the coarse carbon fiber rope 10 from loosening, and the woven coarse carbon fiber rope 10 is removed from the rope reel 14, thus completing the production of the large-diameter coarse carbon fiber rope.

[0045] Each thin carbon fiber rope 6 is composed of at least 3 carbon fiber tows, and each carbon fiber tow is twisted from 1000 to 3000 carbon fiber filaments; the diameter of the carbon fiber filament is 5 to 10 μm, the tensile strength is 3.5 to 7 GPa, and the elastic modulus of the carbon fiber filament is 200 to 600 GPa; the thick carbon fiber rope 10 formed after plying has a diameter of 10 to 60 mm and a tensile strength of 3 to 6 GPa.

[0046] The large diameter carbon fiber rope braiding device described in the present invention is a complete set of devices designed to realize automatic braiding of carbon fiber ropes. Figure 1 As shown, the main components include a rope twisting frame 11, a rope twisting motor 12, a rope twisting shaft 13, a rope splitter 7, a slide rail 8, a tensioning shaft 5, a large gear 3, a small gear 4, a tensioning motor 2, a tensioning bracket 1, a rope collection shaft 14, a rope collection motor 15, a proximity switch 9, and a control system. Its working principle is as follows: 4 to 8 strands of fine carbon fiber rope 6 are selected, each strand of fine carbon fiber rope 6 being twisted from multiple carbon fiber filaments; the pre-treated strands of fine carbon fiber rope 6 are arranged in a petal-like pattern and twisted using a rotary twisting method to form a tensioned fine carbon fiber rope; the tensioned strands of fine carbon fiber rope 6 are twisted using a twisting mechanism to ultimately form a large-diameter carbon fiber rope (referred to as a thick carbon fiber rope). The braided large-diameter carbon fiber rope is then tensioned and coiled to form a finished product.

[0047] The tightening assembly described in the present invention is used to stiffen 4 to 8 strands of fine carbon fiber ropes 6. When the fine carbon fiber ropes 6 pass through the rotating tightening shaft 5, they are continuously tightened under the action of the spiral groove. Then, multiple strands of fine carbon fiber ropes 6 are twisted together behind the rope splitter 7, and move forward under the guidance and driving action of the spiral groove in the rotating rope twisting shaft 13, and are finally wound around the rope collecting shaft 14.

[0048] The length of the slide rail 8 of the present invention is preferably 1 to 3 meters, and two slide rails 8 are preferably provided. A proximity switch 9 is provided at each end of one of the slide rails 8. The signal output end of the proximity switch 9 is connected to the control system, which is further connected to the control ends of the rope twisting motor 12 and the rope collection motor 15. When one of the proximity switches 9 is triggered, the speed of the corresponding motor is adjusted, so that the rope splitter 7 always slides back and forth between the rope tightening assembly and the rope twisting assembly during the rope braiding process.

[0049] Compared with conventional carbon fiber rope weaving equipment, the advantages of the present invention are as follows: 1) The special design of the tensioning structure, the tensioning motor drives the large gear to rotate, and the large gear drives multiple (preferably 4 to 8) small gears to rotate synchronously, thereby achieving uniformity in the tensioning of the fine carbon fiber rope, and providing a guarantee for the uniformity of the large-diameter carbon fiber rope structure; 2) The rope splitter adopts a frustum structure, and the outer surface of the frustum is provided with multiple concave rope grooves (preferably 4 to 8), and the fine carbon fiber rope is placed in the rope groove, which can effectively prevent the fine carbon fiber rope from being entangled together before the strands are woven during the tensioning process, thereby further ensuring the uniformity of the large-diameter carbon fiber rope structure and the smooth woven process; 3) The twisting process adopts automatic control. During the tensioning and twisting process of the fine carbon fiber rope, the rope splitter is controlled by the interlocking control of the proximity switch and each motor to slide along the slide rail to ensure uniform tensioning and prevent the coarse carbon fiber rope from being locally loose or too tight.

[0050] The large-diameter carbon fiber rope braiding device described in the present invention can be used to produce large-diameter carbon fiber ropes with large diameters and compact and uniform structures, solving the common problems of loose structures and small diameters in existing carbon fiber ropes. The large-diameter carbon fiber ropes produced by the present invention have high strength and good stability, and are not easy to break after long-term use. At the same time, the production efficiency of the carbon fiber rope and the degree of automation of the equipment are improved.

[0051] Currently available carbon fiber ropes are not suitable for pulling large and thick soft felts, especially when used in high-temperature environments, where their performance deteriorates and they can oxidize or break. However, the carbon fiber rope produced using the large-diameter carbon fiber rope braiding device described in this invention has high strength and is capable of pulling large and thick soft felts. It can also be used in continuous carbonization furnaces and graphitization furnaces for long periods of time (over one month) without oxidation or breakage.

[0052] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
