细纱机负压系统自动清棉技术

Automatic Cotton Blowing Technology with Negative Pressure System on the Spinning Frame

针对人工掏棉的弊端,阐述了自动清棉技术在吸棉负压系统中的运用,从滤网结构分析、剥棉机构选择、运动体选择和常压区域的建立等方面,建立细纱机自动清棉负压系统结构模型。指出:细纱机吸棉负压系统在纺纱过程中不可或缺,自动清棉技术采用圆周滤网等有效设计,实现笛管口的负压始终恒定,可以选择较低的初始负压,减小风机功率;与人工掏棉相比,实际能耗降低15%,剥棉动作自动完成,有效减轻劳动强度,且可节省人工5%;采用自动清棉技术,能确保纱线品质,进一步提高细纱机自动化程度。

As to the disadvantages of artificial cotton blowing, the automatic cotton blowing technology with negative pressure system is described. The structural model is established for the automatic cotton blowing system with negative pressure on the spinning frame considering the factors including the mesh structure analysis, selection of stripping mechanism and the motion parts and the establishment of atmospheric area. It is pointed out that the negative pressure system is an indispensable part in the process of spinning, the circumferential strainer design can keep constant negative pressure of the flute. The initial negative pressure can be adjusted low for less power consumption. Comparison with the artificial blowing process, the actual energy consumption of the automatic product is reduced by 15%. The cotton stripping actions are automatically completed,effectively reducing the labor intensity with labor saving 5 %. The automatic blowing technology can ensure yarn quality, further reinforcing the automation of the spinning frame.
