络筒机筒纱吸嘴吸头成功率的研究

Study on the success rate of yarn suction nozzle in winding machine

从纺纱品种、络筒工艺、机械结构、动作逻辑等方面对影响络筒机筒纱吸嘴吸头成功率的问题进行分析与探讨,提出了加大风机负压、增大支臂平衡气压、筒纱吸嘴点动吸纱、减少启动切纱并优化启动切纱吸头逻辑、优化钢梳齿形、磨砂处理钢梳背面和优化槽筒正反转程序等提高一次吸头成功率的有效措施,以提高棉纺厂的生产效率、提高筒纱质量、大幅降低挡车工的劳动强度。

The problems affecting the success rate of the suction nozzle of the winding machine were analyzed and discussed from the aspects of the spinning varieties,winding process technology,mechanical structure,action logic,etc.Some effective measures such as increasing the negative pressure of the fan,increasing the balance air pressure of the arm,applying dynamic suction of the suction nozzle of bobbin yarn,reducing the times to cut yarn at start-up,optimizing the logic for cutting and absorbing yarn at start-up,optimizing the shape of steel comb teeth,sanding treatment on steel comb back,and optimizing the positive and negative rotation program of yarn winding roller,etc.were put forward to improve the success rate of yarn suction nozzle,improve the production efficiency of cotton mills,enhance the quality of bobbin yarn,and significantly reduce the labor intensity of workers.
