Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber manufacturing, in particular to a carbon fiber manufacturing yarn laying device. Background Art

[0002] Carbon fiber has excellent properties, including low density, high strength, high modulus, high temperature resistance, and chemical corrosion resistance. Textile processing can improve these properties of carbon fiber, enabling it to be better applied in fields such as aerospace, sports equipment, and the automotive industry. The carbon fiber textile manufacturing process often requires the use of a yarn laying device. However, its actual operation still has some defects.

[0003] Carbon fiber manufacturing yarn laying devices often require workers to manually operate the pay-off, which will result in uneven pay-off speeds and difficulty in achieving synchronous yarn laying operations for multiple groups of carbon fiber yarns, affecting the processing effect. In addition, since the device is fixed, it is difficult to flexibly adjust the laying starting height according to the usage requirements of different yarn laying tables. Based on this, we propose a new type of carbon fiber manufacturing yarn laying device to provide better use results. Utility Model Content
