工作时，后罗拉胶辊35、中罗拉胶辊4、前罗拉胶辊30顺时针旋转，后罗拉轴32、中罗拉轴3、前罗拉轴1逆时针旋转，把纱线输送到导纱钩36到钢领38，绕在锭管37旋转加捻形成纱线，其中后罗拉轴32中罗拉轴3、前罗拉轴1为主动旋转，后罗拉胶辊35中罗拉胶辊4、前罗拉胶辊30为被动旋转，一般中罗拉轴3的转速是后罗拉轴32的1.1-1.8倍，前罗拉轴1的转速是中罗拉轴3的10-100倍，粗纱经过牵伸变细，由于中罗拉胶辊4和前罗拉胶辊30速度比大，须条急剧变化，通过设置上销盖板组件使上销盖板6、下销2、输送带7形成稳定摩擦空间，使上销盖板6弧面和下销2弧面形成一个稳定的配合，以此控制须条。
上述纤维须条输送机构通过设置上销盖板组件，使其维护简单，能节约维护保养成本和时间，而且减少了牵伸功耗。但在上述纤维须条输送机构安装过程中，由于装置加工精度和安装水平等原因会出现包含且不限于下述这些问题。
如图7所示，摇架9整体相对下销2偏斜；如图8所示，下销2相对前罗拉轴1、中罗拉轴3偏斜；如图9所示，上销盖板组件51相对摇架9偏斜；以及上销盖板相对盖板支撑件的偏移，都会导致上销盖板6弧面和下销2弧面不能形成一个稳定的配合间隙，出现纱线质量波动。
本发明所要解决的技术问题是解决现有技术的上述不足而提供一种纺纱机的须条输送机构，使其能够方便调整上销盖板与盖板支撑件之间的空间关系而使上销盖板弧面和下销弧面形成一个稳定的配合间隙。
本发明解决上述技术问题所采用的技术方案为：一种纺纱机的须条输送机构，其包括罗拉墩、铰接在罗拉墩上的摇架，罗拉墩上沿出线方向依次活动设有中罗拉、前罗拉，摇架上沿出线方向依次活动设有中罗拉胶辊、前罗拉胶辊，所述中罗拉和前罗拉之间的罗拉墩上设置下销，下销上表面的中部设置弧形面，下销上方设置上销盖板组件，上销盖板组件包括与下销弧形面凹凸相配的弧形面的盖板、环形输送带、涨紧件，环形输送带套在盖板和中罗拉胶辊外表面上，其特征在于：所述上销盖板与盖板支撑件之间通过万向节机构连接。
更具体地，所述万向节机构包括铰接块座、铰接块、铰接块短轴、铰接块长轴，铰接块座固定在上销盖板上，铰接块长轴固定在盖板支撑件内，铰接块上孔套在铰接块长轴上；铰接块短轴固定在铰接块座，铰接块下孔套在铰接块短轴上；铰接块上与铰接块短轴、铰接块长轴配合的孔大于铰接块短轴、铰接块长轴的轴直径，且铰接块上的上孔、下孔倒圆角或倒角。
更具体地，所述万向节机构包括十字铰接块、铰接块座，铰接块座固定在上销盖板上，十字铰接块上设置相互垂直的上销孔、下销孔，长轴可转动地连接在上销孔上并且其二端固定在盖板支撑件上，短轴可转动地连接在下销孔上并且其二端固定在铰接块座上，由于长轴和短轴十字交叉且都能与铰接块转动，因此，上销盖板相对盖板支撑件能做万向转动。
更具体地，所述万向节机构包括铰接块座上的球形孔、铰接块、盖板支撑件的球形孔，铰接块二端分别设置球体，球体插入球形孔中，球体插入球形孔中，这样当铰接块座固定在上销盖板上，上销盖板相对盖板支撑件能做万向转动。
更好地，上述铰接块采用弹性材料，这样上销盖板与盖板支撑件之间的弹性更好，更容易调节位置。
更好地，还设置隔距块，隔距块固定在上销盖板二侧边上，这样，上销盖板弧面和下销弧面之间通过隔距块隔开而形成一个稳定配合间隙。
与现有技术相比，本发明的优点在于：由于上销盖板与盖板支撑件之间通过万向节机构连接，因此，上销盖板与盖板支撑件之间的空间位置可以方便调整，从而可以方便调整上销盖板与下销之间的位置关系、盖板支撑件与摇架之间的位置关系，这样能够使纱线质量稳定，出现意外牵伸情况大幅度减少。

上销盖板6与盖板支撑件13之间通过万向节机构连接，这样，盖板支撑件13与上销盖板6之间可以根据环境而任意变化方向，使其能够方便消除装置制造时产生的误差和安装环境发生的误差。
万向节机构具体可有以下几种结构。
如图10、图11所示，万向节机构包括铰接块座18、铰接块17、铰接块短轴23、铰接块长轴24，铰接块座18固定在上销盖板6上，铰接块长轴24固定在盖板支撑件13内，铰接块17上孔套在铰接块长轴24上；铰接块短轴23固定在铰接块座18，铰接块17下孔套在铰接块短轴23上；铰接块17上与铰接块短轴23、铰接块长轴24配合的孔大于铰接块短轴23、铰接块长轴24的轴直径，且铰接块17上的孔倒圆角或倒角，使上销盖板6相对盖板支撑件13能够做万向转动。

如图13、图14所示，万向节机构包括铰接块座27上的球形孔271、铰接块28、盖板支撑件13的球形孔131，铰接块28二端分别设置球体281、282，球体281插入球形孔271中，球体282插入球形孔131中，这样当铰接块座27固定在上销盖板6上，上销盖板6相对盖板支撑件13能做万向转动。
上述铰接块28采用弹性材料，这样上销盖板6与盖板支撑件13之间的弹性更好，更容易调节位置。
如图2所示，还设置隔距块20，隔距块20固定在上销盖板6二侧边上，这样，上销盖板6弧面和下销2弧面之间通过隔距块20隔开而形成一个稳定配合间隙。
