Background
The high-performance carbon fiber is light in weight, has excellent performances of high strength, high modulus, high temperature resistance, corrosion resistance, scouring resistance, sputtering resistance and the like, also has good designability and compositability, and is an indispensable strategic emerging material for building equipment such as rockets, satellites, missiles, fighters, ships and the like; the density of the high-performance carbon fiber is less than 1/4 of that of steel, but the strength of the high-performance carbon fiber is 5-7 times that of the steel; compared with an aluminum alloy structural member, the structural member made of the carbon fiber composite material can be reduced by 20-40% in weight; compared with a steel metal structure, the weight of the structure made of the carbon fiber composite material can be reduced by 60-80%.
With the progress of technology, the application of carbon fiber in the civil field is wider and wider, in order to meet the demands of the civil market and the demands of reducing production cost, the carbon fiber in the civil field is developed towards a wide filament direction, and the carbon fiber with 48K or above is the current key development direction. The carbon fiber has the characteristics of softness and brittleness, the 48K yarn is composed of 48000 fine fibers, although the 48K yarn has extremely strong breaking force in the length direction, the 48K yarn is extremely fragile in the transverse direction, any fine external force can damage the 48K yarn, the external force interference in the transverse direction of the fiber needs to be strictly controlled in the production process, and in addition, the consistency of the forming width of the tows greatly influences the subsequent process. The winding machine used as the last process of the carbon fiber production line is responsible for winding the carbon fibers into a cylindrical spindle for processing the rear-section composite material, and the quality of the winding and forming of the spindle directly influences the quality of the rear-section composite material, so that the winding link requires no damage to the carbon fibers, consistent width and complete forming of the spindle.

The spindle winding mechanism winds the fiber onto the bobbin of the spindle according to the production line operating speed. When the spindle is wound, the yarn guide in the reciprocating yarn guide mechanism transversely reciprocates to drive the fibers to be uniformly wound on the bobbin of the spindle, and the fibers are transversely driven by the yarn guide to form a winding angle alpha and are wound on the bobbin. Reciprocating yarn guide mechanism drives the fibre and is horizontal reciprocating motion, applys a horizontal power all the time to the fibre, and the fibre is influenced to soft fibre easily, also can influence fibrous width, when coiling fibre, receives the influence of coiling angle and tension, and the fibre can produce certain lateral displacement on the spool surface, and this lateral displacement can produce "the silk of rubbing" for the fibre fluff (hinder the silk) and make the fibre narrow, influence fibre quality and silk width. This phenomenon is increasingly apparent for fibers at 48K and above. In addition, when the fiber reciprocates, the fiber swings in a reciprocating manner at the position of the fiber feeding wheel, so that the fiber is easy to generate 'edge rubbing' at the position of the fiber feeding wheel, and the quality of the fiber is influenced.
