摘　　要：用不同长度纤维在FA322B型并条机上并条牵伸,通常需要根据人工经验调整并条机牵伸机构的部分结构参数,较难达到最佳牵伸效果。为此,在分析FA322B型并条机牵伸机构工作原理的基础上,通过建模优化方式,得到主牵伸区中二皮辊和二罗拉横向距离的最佳调整位置,为实际生产中工艺调整提供理论指导。同时研究二皮辊和二罗拉横向距离大小对牵伸效果的影响。研究结果表明:二皮辊和二罗拉横向距离选取不当会致使纤维黏附于前皮辊之上,严重影响牵伸效果,因此在实际生产中,需要合理调整二皮辊和二罗拉横向距离,以保证良好的牵伸效果。For drawing and drafting fibers of different lengths on the FA322B drawing frame,partial process parameters of the drafting mechanism of the drawing frame are needed to be adjusted according to artificial experiences,but it is hard to achieve optimal drafting effect.In order to solve this problem,based on analyzing the operating principle of the drafting mechanism of the FA322B drawing frame,the modeling optimization was adopted to obtain the optimal adjustment position of the transverse distance between the second upper and lower rollers,providing theoretical guide for the process adjustment in actual production.The influence of the transverse distance between the second upper and lower rollers on the drafting effect was also investigated.The results indicate that improper transverse distance between the second upper and lower rollers can cause fibers to adhere to the front upper roller,thereby greatly affecting the drafting effect.Therefore,transverse distance between the second upper and lower rollers should be adjusted carefully to ensure good drafting effect in actual production.
