粗纱机卷绕成形理论分析与工艺配置

Theoretical Analysis and Processing Configuration on Winding Shaping of Roving Frame

探讨粗纱机卷绕成形的理论分析与工艺配置。为了正确配置粗纱卷绕成形齿轮,分析了传统方法中以粗纱条的椭圆形截面形态作为计算粗纱卷绕成形工艺的不足之处,提出了利用粗纱整体卷装和单根粗纱条的椭圆形截面形态相结合计算粗纱成形工艺的方法。以TJFA458A型粗纱机为例,经过实际工艺上车验证,达到了生产所需的要求。结果表明:利用新方法计算的粗纱卷绕成形工艺,减少了频繁试车,理论计算工艺与实际生产工艺更为接近。

Theoretical analysis and processing configuration on winding shaping of roving frame were analyzed. In order to properly configure roving winding shaping gear, the shortages of traditional calculating roving winding forming technology was analyzed, new calculating method was put forward, i. e. combined roving package and single roving oval cross section shape. Taking TJFA458A roving frame as example, after actual test, production required can be reached. The result shows that the frequent adjustment using the roving winding forming technology by the new method can be reduced, the theoretical calculation processing and the actual production processing are closer.
