Description

一种纱线的加捻装置及连续加捻方法 技术领域
本发明涉及纺织领域，尤其涉及一种纱线的加捻装置及连续加捻方法。
背景技术
在利用棉纱纺织成棉织物时，需要对纱线进行加捻处理，加捻是为了将两根或两根以上单纱固定成股线，并得到较好的成型与强力等质量状态，若不加捻处理，两根或两根以上的单纱在一起就没有抱合，受外力则会分开，影响成品质量。
加捻是使纤维条成为纱线的必要手段，加捻丝又其名倍捻丝，还有称有捻丝，总之是让长丝加上捻度。加捻丝适用针织机织，涵盖纺织所有领域，规格也因粗细(15D-50D为超细旦)150D以上为粗规格丝，捻度大小用每厘米多少个捻为单位，民间有称80捻-500捻为弱捻，500捻-1000捻为中度捻，1000捻以上称之强度捻。捻的方向为S向和Z向，按照织物风格需要是单根Z捻还是s和z配对使用。
加捻的作用有：增加丝线的强力和耐摩擦性能，以减少起毛和断头，提高丝织物的牢度；使丝线具有一定的外形和花色，赋予织物外观以折光、绉纹或毛圈、结子等效应；增加丝线的弹性，提高织物的抗皱性能(仿记忆免烫面料)和透气性(强捻面料)，并使织物穿着凉爽、舒适。
倍捻机是一种常用的加捻设备，但是其结构复杂，设备昂贵，且在加捻过程中纱线的张力过大。
发明内容

图2为加捻装置的立体图；
图3为图2中A-A的剖视图；

图5为图4中卷绕机构的***图。
具体实施方式
如图1～图3所示的加捻装置，包括机架以及安装在机架上的中空轴8、 驱动机构、卷绕机构4和减速机构。
中空轴8内部为供纱线穿过的通道，图3中B箭头表示纱线的运动方向，单股或多股纱线直接进入中空轴8内。
驱动机构包括加捻电机2，加捻电机2通过固定件1固定安装在机架上，中空轴8在加捻电机2的驱动以第一转速旋转。
本实施例中，加捻电机2的主轴与中空轴8为同一部件，即加捻电机2的主轴与中空轴8同轴设置。另外，还可以使加捻电机2的主轴与中空轴8异轴设置，通过传动部件保持加捻电机2与中空轴8联动，所用的传动部件如齿轮或传动带等。
中空轴8的中部装有加捻臂3，中空轴8由加捻臂3中部穿过。本实施例中，加捻臂3固定在中空轴8上，在中空轴8转动的同时，带动加捻臂3同步转动，图3中C箭头表示加捻臂3和中空轴8的转动方向。
加捻臂3的一侧设置有纱线导向机构，另一侧安装有平衡块9，用于保持加捻臂3转动过程中两侧的平衡。
中空轴8的中部还设有与其内部通道连通的通孔，纱线穿出通孔后经纱线导向机构进入卷绕机构4进行纱线卷收。
本实施例中，纱线导向机构包括位于加捻臂3端部的导向轮11，以及位于导向轮11和通孔之间的导向套10，为保持纱线的具备足够的张力，通孔与导向轮11的纱线呈折弯状，且通孔与导向套10之间的纱线倾斜角度小于导向套10和导向轮11之间的纱线倾斜角度。
本实施例中，加捻臂3的端部连接有延伸至卷绕机构4周面外的导向板12，该导向板12上设置有导向孔13，经导向轮11后的纱线由导向孔13进入卷绕机构4进行纱线卷收。
如图4和图5所示，卷绕机构4由中空轴8带动并以第二转速同步旋转，用于收卷加捻纱线；减速机构，在中空轴8和卷绕机构4间传动配合，用于将输入的第一转速降低为输出的第二转速。
本实施例中，卷绕机构4包括绕线筒41。减速机构为齿轮减速组件，减速机构包括套装在中空轴8的主动齿轮42以及至少一个主动齿轮42啮合且轮轴相对机架固定的变速齿轮组43，绕线筒41内壁设置与变速齿轮组啮 合的轮齿44。
中空轴8的一端伸入绕线筒41内，由主动齿轮42与变速齿轮组43和轮齿44的传动配合，将中空轴8的第一转速降低为驱动绕线筒42的第二转速，以第二转速转动的绕线筒41不断收卷加捻后的纱线，另外，或根据实际需要，在其他机构的牵引下，绕线筒41可同时释放卷收的纱线，如图3中的D箭头所示方向，形成连续加捻。
本实施例中，由于绕线筒41始终处于转动状态，而变速齿轮组43位于绕线筒41，要实现齿轮传动减速，应保持变速齿轮组43的位置不变。因此，变速齿轮组43的轮轴上安装有第一磁性件6，固定在机架的安装座5上设有与第一磁性件6配合的第二磁性件7，第一磁性件6和第二磁性件7位于加捻臂3的上下两侧，通过两者的相互吸合，以固定变速齿轮组43的轮轴位置。另外，绕线筒41的侧面设置有盖板46，为更好固定第一磁性件6，利用导磁座46将第一磁性件6固定。
本实施例中，轮齿44设置在与绕线筒41固定的内齿环47上，且绕线筒41内部中空，为避免绕线筒41的晃动，绕线筒41内设置有至少一个与轮齿44啮合的定位齿轮45，该定位齿轮45的转轴端部也安装有磁性件，也是通过磁性吸合来固定。
以上所述仅为本发明的较佳实施举例，并不用于限制本发明，凡在本发明精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
