Research on Innovative Mechanical Structure Design in Carbon Fiber Ingot Winding Technology

Carbon fiber ingot winding, the final step in the production of carbon fiber, is a crucial process that directly influences the quality of the final product, ensuring the quality of carbon fiber and facilitating smooth processing in the subsequent process. This paper describes the principle of carbon fiber ingot winding, summarises the difficulties of winding carbon fiber ingots, and designs a winding machine that can wind different specifications of carbon fiber ingots. It figures out the folding curve and spiral rise angle in the winding movement of carbon fiber spindles using theoretical knowledge of physical kinematics. It then builds an experimental test platform, prepares the experimental samples, and, based on the needs of the experiment, analyses the process of carbon fiber spindle winding technology. The results demonstrate that the error value between the measurement on the experimental platform and the actual manual measurement remains within 0.01 g, the carbon fiber spindle becomes compact at a tension setting scale value of 5, and the winding end surface remains flat. Furthermore, we find that a larger spiral angle, ranging from 51.7° to 208.5°, enhances the winding’s overlapping effect. The innovative mechanical structure design scheme proposed in this paper has been proven to be effective in process simulation.
