Description

Technical Field

[0001] The present invention relates to the field of carbon fiber production equipment, and in particular to an industrialized device for three-dimensional anti-twist steering of pulp-free carbon fiber. Background Art

[0002] Pulpless carbon fiber is the precursor of finished carbon fiber of various uses and grades. It is an intermediate product in the carbon fiber production process that is processed by electrochemical surface etching and water washing and drying before the sizing process and after high-temperature carbonization. Compared with the finished carbon fiber with a sizing agent protective film on the outer surface and the pre-oxidized silk and raw silk organic molecular chain protected by flexible groups before the carbonization furnace process, the original pulpless carbon fiber is a highly oriented and brittle graphite sheet skeleton material without any protection measures. Its structure is easily destroyed by the jumping of guide rollers and guide wheels, uneven rotation, rough surface, lateral friction, and twisting and twisting perpendicular to the orientation and the running direction of the carbon fiber in the three-dimensional steering process without the protection of sizing agents. It is not easy to obtain. Traditional thermosetting carbon fiber, newly emerging thermoplastic carbon fiber and electroplated carbon fiber, and ceramic carbon fiber under development all require original pulpless carbon fiber. For this reason, original pulpless carbon fiber is also a new carbon fiber variety with the greatest application potential, the most application scenarios, and the most difficult to obtain in the future.

[0003] Mitsubishi Rayon of Japan reported a patent of 'carbon fiber bundle for resin reinforcement and its manufacturing method, as well as carbon fiber reinforced thermoplastic resin composition and molded product' (CN104603351A). The patent only introduced the main components of the sizing agent group on the surface of the carbon fiber, the sizing time and the immersion length of the sizing tank, but did not involve the source, state and device information of the original unsizing carbon fiber; the patent 'experimental carbon fiber sizing device' (CN 205398940 U) involves the sizing process and carbon fiber creel, but did not explain the source of the original unsizing carbon fiber, nor did it make further claims on the shape, characteristics, performance, function, use method and material of the carbon fiber creel; the patent 'preparation method and device of carbon fiber reinforced thermoplastic resin composite material' (CN105348768A) involves the preparation method and device of carbon fiber desizing, electroplating and then sizing. In actual applications, some users directly use thermosetting sizing agent carbon fiber to reinforce thermoplastic resin. Due to the poor compatibility between thermosetting sizing agent and thermoplastic resin, the composite material cannot significantly improve the material performance due to the poor composite interface performance. The sizing agent cannot withstand the process temperature above 280℃ and cannot enhance the high-temperature thermoplastic resin. The thermosetting sizing agent on the surface of the carbon fiber is cracked in a temperature protection atmosphere of about 500-700℃. This desizing process will reduce the performance of the carbon fiber to varying degrees. The desized carbon fiber is then sized with a thermoplastic sizing agent. Not only is the production cost high, but the waste liquid after desizing cannot be recycled and becomes an environmental hazard. The performance of the composite material cannot be stable and optimal.

[0004] The traditional fiber comb produces strong friction on the surface of carbon fiber, and the jumping of the yarn frame, guide roller and guide wheel, the surface finish and the uneven rotation of the bearing, as well as the torsion or twisting of the carbon fiber during the three-dimensional steering process of the carbon fiber damage the structure and performance of the carbon fiber. At the same time, because it is a temporary borrowing device for the three-dimensional steering of non-dedicated native pulp-free carbon fiber, its external dimensions are difficult to accurately position on site, and after being in place, it will affect the normal operation of some adjacent carbon fibers. In addition, the deformation of the fiber teeth and the instability of the yarn frame caused by the three-dimensional steering tension of the carbon fiber will in turn aggravate the deviation of the carbon fiber running track and the disorder of the yarn tow spindle number, and the hair and entanglement caused by the friction will quickly cause the fiber comb to block the teeth, the guide roller and guide wheel yarn frame bearings to jam, and production will be unsustainable.

[0005] As the market demand for high-performance, low-cost thermoplastic sizing agent carbon fiber becomes more and more urgent and the demand is increasing, it is imperative for carbon fiber manufacturers to invent simple, practical, low-cost, performance-undamaged, quality-stable, safe and environmentally friendly methods and devices for industrial mass production of thermoplastic carbon fiber to meet market requirements and expand carbon fiber applications.

[0006] The best method is to directly mass-produce lossless carbon fiber with good performance by utilizing the pulp-free carbon fiber and supporting resources on the existing thermosetting carbon fiber production line. However, the process flow and equipment control of the existing industrial carbon fiber production equipment are fixed, the equipment spacing is small, and the equipment operation and maintenance space are limited. The existing filament combs, mobile yarn frames, tilting rollers and their combinations cannot achieve online lossless three-dimensional steering of pulp-free carbon fiber. Therefore, the key technology for obtaining pulp-free carbon fiber is to first obtain the shape, material, surface and performance of the device---the pulp-free carbon fiber three-dimensional anti-twist steering device---which must avoid damaging the brittle skeleton of the original pulp-free carbon fiber.
