Description

一种环锭纺细纱机的纤维须条输送机构 技术领域
本发明涉及纺纱细纱机须条的输送机构。
 背景技术
参考图1--3，中国专利文献CN211227482U公开了一种环锭纺细纱机的纤维须条输送机构，其包括罗拉墩31、通过摇架握持管33铰接在罗拉墩上的摇架9，罗拉墩31上沿出线方向依次活动设有后罗拉轴32、中罗拉轴3、前罗拉轴1，摇架9上沿出线方向依次活动设有后罗拉胶辊35、中罗拉胶辊4、前罗拉胶辊30，所述中罗拉轴3、前罗拉轴1之间的罗拉墩上设置下销2，下销2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2弧形面凹凸相配的弧形面的上销盖板6、环形输送带7、盖板支撑件13、涨紧弹簧8、涨紧块5，环形输送带7套在上销盖板6和中罗拉胶辊4外表面上，并由涨紧弹簧8涨紧上销盖板6，上销盖板组件连接在摇架9上。
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，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。但也有以下不足：
1.须条在牵伸过程中要求输送带7匀速运行，中罗拉胶辊4和中罗拉轴3形成的摩擦副带动输送带7顺时针旋转，会形成一个对上销盖板6如图2、图3、图5所示的拉力F，同时，输送带7在涨紧弹簧8和涨紧块5作用下涨紧，这个涨紧力也会把F 拉力增大，如图2所示。
2.纺纱过程中，在须条粗细变化、须条各股纤维之间抱合力突变、温湿度变化时该拉力F会波动，拉力F波动有可能会超过上销盖板6的下压力，会使上销盖板6头部抬起，破坏上销盖板6与下销2形成的稳定间隙，引起纱线质量恶化，同时会引起输送带7速度变化而导致纱线质量不稳定。
3.还由于压紧上销盖板6的着力点在输送带7涨紧弹簧8中心，与纺纱过程中输送带6拉力F距离较远，上销盖板6受拉力F拉起时不能提供足够下压力，拉力F波动会使上销盖板6头部抬起，破坏上销盖板6弧面与下销2弧面形成的稳定间隙，导致纱线质量不稳定。
 技术问题
本发明为解决现有技术的上述不足问题而提供一种环锭纺细纱机的纤维须条输送机构，使其能在摇架压紧状态下保持上销盖板与下销之间的间距更稳定。
 技术解决方案
本发明解决现有技术的问题所采用的技术方案为：
一种环锭纺细纱机的纤维须条输送机构，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：所述上销盖板靠近前罗拉胶辊的头部与下销头部之间设置自锁机构，所述自锁机构在摇架压下时纤维须条输送机构工作时上销盖板头部与下纺纱组件头部组合在一起而阻止上销盖板头部抬起纤维须条输送机构，摇架抬起纤维须条输送机构不工作时，上销盖板头部与下纺纱组件头部可脱离。
更具体地，所述自锁机构包括钩突和弯钩，弯钩钩住钩突而锁住，弯钩离开钩突而脱钩。
更好地，所述弯钩为Ｃ型弯钩，这样，更容易钩住钩突而锁住。
更好地，所述上销盖板组件包括主件和连接件，连接件连接在主件二端上，连接件头部与下销头部之间设置自锁机构，所述自锁机构包括钩突和弯钩，连接件头部上设置钩突或弯钩，相应地，下锁头部设置弯钩或弧形钩突，这样容易制造上销盖板组件。
更好地，所述连接件套在主件上，这样连接件与主件的连接更为方便。
更好地，所述自锁机构包括弧形槽中的弧形钩突和弯钩，弧形槽设置在连接件前端上，连接件套在上销盖板的二端上，下锁头部设置弯钩，弯钩钩住钩突而锁住，弯钩离开钩突而脱钩，这样，弧形槽能限制弯钩外移，这样更容易钩住钩突而锁住。
更好地，所述自锁机构设置在上盖板组件头部和下纺纱组件靠近前罗拉轴位置，这样，能够更好地抵消拉力。
 有益效果
本发明的优点在于：由于上销盖板靠近前罗拉胶辊处的头部与下销之间设置自锁机构，在摇架压紧状态下，自锁机构在上销盖板支撑件内弹性压力下能够阻止上销盖板头部抬起，这样能使上销盖板与下销之间间距稳定，从而使输送带运行稳定，纱线指标稳定。摇架抬起后，压紧力消失后，自锁机构能顺利脱开，上销盖板又能方便脱离。

 本发明的实施方式
下面结合附图、实施例对本发明做进一步说明。
如图1-11所示，环锭纺细纱机的纤维须条输送机构，包括罗拉墩31、通过摇架握持管33铰接在罗拉墩上的摇架9，罗拉墩31上沿出线方向依次活动设有后罗拉轴32、中罗拉轴3、前罗拉轴1，摇架9上沿出线方向依次活动设有后罗拉胶辊35、中罗拉胶辊4、前罗拉胶辊30，所述中罗拉轴3、前罗拉轴1之间的罗拉墩上设置下销2，下销2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2弧形面凹凸相配的弧形面的上销盖板6、环形输送带7、盖板支撑件13、涨紧弹簧8、涨紧块5，环形输送带7套在上销盖板6和中罗拉胶辊4外表面上，并由涨紧弹簧8涨紧盖板，上销盖板组件连接在摇架9上。
如图4所示，盖板支撑件13上设置上销弹簧16、弹簧罩15，上销弹簧16置于盖板支撑件13的弹簧槽131中，弹簧罩15弹簧罩15被摇架9下压，经过上销弹簧16传递到盖板支撑件13，上销盖板6通过铰接块17和铰接块座18与盖板支撑件13连接，使上销盖板6得到一个下压力，上销盖板6弧面和下销2弧面形成一个稳定配合间隙。
为抵消环形输送带7回转产生拉力F和涨紧弹簧8、涨紧块5对上销盖板头部抬升力，在上销盖板6靠近前罗拉胶辊30的一侧的头部与下销2头部设置自锁机构，所述自锁机构在摇架压下时纤维须条输送机构工作时上销盖板头部与下纺纱组件头部组合在一起而阻止上销盖板头部抬起纤维须条输送机构，纤维须条输送机构不工作时，上销盖板头部与下纺纱组件头部可脱离。以下具体描述自锁机构，但这些自锁机构只是部分实施例，是为了更好地说明本发明而不是仅限制下述实施例。
实施例1：

如图5、6所示，自锁机构包括弧形钩突611和C型弯钩22，弧形钩突611设置在连接件61前端上，连接件61通过其内腔612套在上销盖板6的二端上，这样上销盖板6与连接件61组合成一体，成为上销盖板组件，C型弯钩22设置在下销2的前端上，所述C型弯钩22可套在弧形钩突611上而将二者连接在一起。
本实施例中下销2为下纺纱组件，下纺纱组件包括下销52和纺纱块57，纺纱块57可拆卸地连接在下销52上。
上述下销52和纺纱块57还可以有多种变化的配合。
如图7所示，自锁机构的连接件61在作用力S的作用下，连接件61头部弧形钩突611与下销2的C型弯钩22结合而自锁，使连接件61位置固定，从而使上销盖板6相对下销2位置固定，拉力F对上销盖板6上拉力抵消。本实施例中，连接件61还受下销20连接件61的圆弧面推力D作用，这样效果更好。
如图8所示，当摇架9抬起时，摇架9带动盖板支撑件13向上移动，带动盖板支撑件13拉起上销盖板6和连接件61，连接件61脱开下销2的C型弯钩，完成分离。

如图4所示，来自摇架9的压力N经过弹簧16、盖板支撑件13形成对上销盖板6压力S。
如图9所示，自锁机构包括弧形槽621中的弧形钩突6211和弯钩23，弧形钩突6211设置在连接件62前端上，连接件62套在上销盖板6的二端上，这样上销盖板6与连接件62组合成一体，成为上销盖板组件，弯钩23设置在下销20的前端上，所述弯钩23插入弧形槽621中时，弯钩23套在弧形钩突6211上而将二者连接在一起，弧形槽621相对弯钩23一侧能够限位弯钩23移动。
本实施例中下销20为下纺纱组件，下纺纱组件包括下销52和纺纱块57，纺纱块57可拆卸地连接在下销52上。
上述下销52和纺纱块57还可以有多种变化的配合。
如图10所示，连接件62在力S作用下，连接件62头部弧形钩突6211与下销52的弯钩23结合自锁，使得连接件62位置固定，从而使上销盖板6相对下销20位置固定，F拉力对上销盖板6上拉力抵消。本实施例中，连接件62还受下销20连接件62圆弧面推力D作用，这样效果更好。
如图11所示，当摇架9抬起时，摇架9带动盖板支撑件13向上移动，带动盖板支撑件13拉起上销盖板6和连接件62，连接件62脱开下销20的弯钩，完成分离。
