    摘要:為了解決三通道環錠細紗機牽伸區只有后區能獨立設定、導致細紗中占比較少纖維束對應的牽伸倍數過大的問題,提升細紗機紡紗質量和紡紗效果,分析了目前牽伸結構存在的主要問題,詳細介紹一種雙區牽伸均可獨立設置的新牽伸結構及應用注意事項。指出:新牽伸結構參照原三通道后羅拉的型式,將中羅拉也改造成三通道,保證后區為自由牽伸,前區為上、下膠圈式牽伸;新牽伸結構為耦合細紗的智能紡牽伸結構提出新思路,能解決三通道環錠細紗機因后區牽伸倍數獨立設定導致的、細紗中占比較少纖維束對應的后區牽伸倍數過大以及前區共用膠圈引起的細紗品質下降等問題;其傳動伺服電機應在車頭、車尾合理設置,所用上、下銷和膠圈牽伸器材需重新考慮,使用抽氣式集聚紡技術和T形對稱單槽或者三槽式負壓工藝片實現纖維集聚。

    Abstract:In order to solve the problem that the draft multiple is too large for the smaller number fiber bundles in the yarn result from that only the back zone of the draft zone of three-channel ring spinning frame can be set independently,and improve spinning quality and effect of spinning frame,the chief problems existing in current draft structure are analyzed,and a new draft structure with independently settable double-zone draft and the matters needing attention in application are introduced.It is pointed out that the new draft structure is referred to the form of the original three-channel back roller,and the middle roller is also transformed into three-channel to ensure that the back zone is free draft and the front zone is upper and lower apron draft.A new idea is proposed for the intelligent spinning draft structure of coupled spinning from the new draft structure,which can solve the problems that the draft multiple is too large for the smaller number fiber bundles in the yarn result from that only the back zone of the draft zone of three-channel ring spinning frame can be set independently,and spinning quality decline caused by the common apron in the front zone.The driving servo motor should be set up reasonably in the front and rear of the vehicle,and the drafting accessories of upper and lower pins and apron should be reconsidered.The fiber compacting should be realized by using the pumping compact spinning technology and T-shaped symmetrical single or three-groove negative pressure process sheet.
