Description

Technical Field

[0001] The utility model belongs to the field of carbon fiber processing, and in particular relates to a carbon fiber tow guiding device. Background Art

[0002] Carbon fiber is a fiber material with a carbon content of more than 90%. In terms of material performance, it has both the inherent characteristics of carbon materials and the softness of fibers. Due to its superior performance, it is widely used in aerospace, automotive, electronics, machinery, chemical, sports equipment and other industries.

[0003] The production process of carbon fiber is a system engineering involving multiple disciplines and fields, mainly chemical engineering, polymer physics and chemistry, fiber material physics and chemistry, chemical engineering, textiles, metallurgy and machinery. Therefore, the production technology of carbon fiber is a complex and difficult task.

[0004] For a long time, the production process of carbon fiber has been composed of oxidation of raw silk ingots, low-temperature carbonization, high-temperature carbonization, surface treatment, sizing and drying, and winding. In the process of carbon fiber processing, oxidized silk after oxidation, low-carbon silk after low-temperature carbonization, and carbon fiber after high-temperature carbonization all have their specific application scenarios. However, unlike carbon fiber after high-temperature carbonization, oxidized silk and low-carbon silk have not undergone surface treatment, sizing and drying, so they are generally not wound. The traditional way of collecting silk is to collect silk by manual drawing. The efficiency of manual collection is low, and the size of single carbon fiber is extremely small. When multiple strands are drawn, it is very easy to have hair. The shorter hair has extremely high rigidity and is very easy to pierce the skin of the operator. At the same time, depending on the indoor environment, the air will be full of floating carbon fiber broken silk, and the working environment is not conducive to the long-term work of the operator.

[0005] In order to solve the above problems, the industry needs a wire guiding device for collecting carbon fiber pre-oxidized yarns and low-carbon yarns, which can protect operators from harm while meeting the requirements of yarn collection. Summary of the invention
