我国新型纺织机械研制工作又获得突破性进展,列入国家“七五”纺织业技术改造计划的抽气式气流纺纱机由航空部远东机械制造公司研制成功,今年四月通过部级鉴定,现已投入批生产。 QF-1型气流纺纱机利用机械离心力与空气动力相结合的自由端纺纱原理进行气流纺纱,属于国际八十年代初先进水平的新型抽气式气流纺纱机。其结构复杂,技术先进,它采用纺杯间接式轴泵、开关车程序控制、自动排杂、自动留头、往复绕纱、筒纱半自动输送、
The development of new textile machinery in China has achieved breakthrough progress. The pumping-type air spinning machines listed in the National “7th Five-Year Plan” for the technological transformation of the textile industry were successfully developed by the Far East Machinery Manufacturing Company of the Ministry of Aviation and passed the ministerial appraisal in April this year. Has been put into batch production. The QF-1 air-jet spinning machine utilizes the principle of free-end spinning combined with mechanical centrifugal force and aerodynamics to perform air-spinning. It is a new type of air-drawing air spinning machine with international advanced level in the early 1980s. Its structure is complex and its technology is advanced. It adopts indirect shaft pump of spinning cups, program control of switch car, automatic impurity removal, automatic head retention, reciprocating winding, semi-automatic conveying of package yarn,
