Description

可升降并可变换旋转角度的针织机除尘装置 【技术领域】

【背景技术】
针织机是纺织行业中最常用的织布机械，针织机在织造过程中会产生大量的纱毛，且纺织原料表面附着的纱毛会在织造过程中散落，不断产生的纱毛如不及时清理，将会堆积在机器及布料表面而影响机器的正常运行，并造成加工布料的次点增多，而且也会污染针织机及周围环境，并对工人的健康造成影响。对于机台表面及纺织原料表面的除尘，现有针织机普遍采用多台风扇除尘方式，它是在一个旋转的环形框架上的不同位置间隔地装设有多台风扇，当环形框架旋转时，每台风扇只在特定的圆周内旋转除尘。这种除尘方式的缺陷是显而易见的，由于这类装置的除尘风扇多达6到8台，不仅占用了机台上方的大量空间，显得杂乱无章，且运行过程中产生了大量的噪音，并消耗了较多的电能。更为重要的是，针织机在运行过程中，纺织原料表面纱毛会在织造过程中四处散落，并附着于织机的不同高度上的不同部位，而传统的除尘装置由于位置固定且不能上下移动，因而只能对某个固定的部位除尘，因此大大影响了除尘效果和产品质量。

如图6、图7所示，本发明的可升降并可变换旋转角度的针织机除尘装置设置在针织机的机台上方的送纱器圆盘中央，其在未升起时，可对机台上的送纱器D、纱钩E等部位进行除尘。在升起后可对位于机台上方的线槽A、抽风或送风管道抽送风管B及其它管道C
等积尘部位进行除尘。本装置的升降位置可根据需要通过控制机构80进行设定和调节。下面将结合附图及实施例对本发明做更详细的描述。
在针织机送纱器圆盘101中央固定有升降机构40，其上端与所述中央旋转体30相连接，其可推动所述中央旋转体30及除尘风扇10上下移动至针织机的不同除尘部位。所述升降机构40可以是气压传动机构或液压传动机构，也可以是丝杆传动机构。本实施例中，该升降机构40为第一气压传动机构41。如图1、图2及图5所示，该第一气压传动机构41包括第一气缸411，该第一气缸411的底部固定在针织机送纱器圆盘101中央，第一气缸的活塞杆4111上端固定有法兰412，该法兰412中央固定有向上方延伸的固定柱413，该固定柱413上端穿过所述进气旋转复合体50并插入所述主轴35内，固定柱413与主轴35用螺钉固定。在第一气缸411上下各连接有一个第一进气管414，该第一进气管414与外部的空气压缩机相连接，空气压缩机则与所述控制机构80相连接。如图7所述，当第一气缸411处于未工作状态时，除尘风扇10A、10B可对送纱器、纱钩E等部位进行除尘。如图8所示，当第一气缸411内进气时，推动第一气缸的活塞杆4111向上移动，活塞杆4111经法兰412、固定柱413推动所述主轴35向上移动到设定的除尘位置。此时，除尘风扇10A、10B可对线槽A，抽风或送风管道B及其它管道C、照明器件F、车间天花板G等进行除尘，因此，实现了对针织机及周围环境的全方位除尘。
本发明的另一实施例中，所述第一气压传动机构为丝杆传动机构42，如图3所示，该丝杆传动机构42包括外套421、第二电机422、齿轮组423、丝杆424、螺母425及传动杆426。所述第二电机422为步进电机，其与齿 轮组423构成减速机构，所述第二电机422的电机轴与齿轮组的第一齿轮4231相连接，齿轮组的第二齿轮4232与第一齿轮4231相啮合。所述丝杆424装在外套421内，丝杆424的下端固定有第二齿轮4232。丝杆424与位于其下端的螺母425螺纹连接，螺母425上部固定有传动杆426，该传动杆426套设于丝杆外部，所述传动杆426上端与所述主轴35用螺钉固定。所述第二电机422经齿轮组423带动丝杆424转动，并通过螺母425推动传动杆426上下移动而带动主轴35上下移动。
如图1、图2所示，在所述升降机构40上部设有进气旋转复合体50，其用于为风扇连接杆角度变换机构60供气，并与中央旋转体30相连接。如图4所示，该进气旋转复合体50包括旋转部51和静止部52。所述静止部52为套状体，其置于所述旋转部51之内，并与连接于所述第一气缸的活塞杆的连接盘上的固定柱413套接固定。所述旋转部51为中空柱状体，其通过轴承53转动连接于静止部52外部，使得静止部52始终呈静止状态，而旋转部51则绕其转动。所述旋转部51外侧与连接于中央旋转体外侧的竖向连接板36相连接，由中央旋转体30带动其旋转。在所述静止部52上部设有进气口521，静止部52内设有与该进气口连通的竖向气道522。与所述竖向气道522相对应，在所述旋转部51内壁上设有与所述竖向气道522连通的内凹的环形气道511，该环形气道511与横向的出气口512相连通。所述进气口521与外部的空气压缩机相连接，所述出气口512通过一进气接头与所述风扇连接杆角度变换机构60相连通，通过该动静配合的结构，实现了为风扇连接杆角度变换机构60供气，且在旋转部51随中央旋转体30旋转时，由于静止部52不动而避免气管的缠绕。
如图1、图2所示，在所述进气旋转复合体50上部设有中央旋转体30。如图5所示，该中央旋转体30包括壳体31、第一电机32、减速机构33、碳刷34及主轴35。所述壳体31为圆形壳体。所述第一电机32为步进电机，其固定于壳体31顶部。在壳体31内设有减速机构33、碳刷34及主轴35。 所述减速机构33为齿轮减速机构，其包括与第一电机32的电机轴连接的第一组齿轮331、332和与第一组齿轮331、332的输出轴连接的第二组齿轮333、334，所述第一电机32的电机轴与所述减速机构33相连接。所述主轴35为内部中空且固定不动的固定轴，其固定在壳体31内中央，其上下两端由轴承36支承，其下端从壳体31伸出，并与插入其内的连接于第一气缸的活塞杆的连接盘上的固定柱413套接固定。所述碳刷34装在主轴35上，并分别与所述控制机构80、第一电机32、风扇连接杆角度变换机构60及风扇角度变换机构70相连接，用于中央旋转体30的供电连接。在所述壳体32外侧连接有竖向连接板36，其与所述壳体31铆接固定，并与所述进气旋转复合体50在其出气口512处用螺母与旋转复合体50固定。当第一电机32转动时，其带动壳体32同步转动，并通过固定在壳体32上的竖向连接板36带动进气旋转复合体50的旋转部51转动。
如图1、图2所示，在所述中央旋转体30上连接有至少一组风扇连接杆20，本实施例中，在所述中央旋转体30上连接有一组风扇连接杆20，一组风扇连接杆20包括第一风扇连接杆20A和第二风扇连接杆20B。该第一风扇连接杆20A和第二风扇连接杆20B均为多节式可伸缩杆，其可延伸至机台的除尘部位，且该长度可根据需要进行调节。所述第一风扇连接杆20A的一端端部设有连接块21，第一风扇连接杆20A通过该连接块21用柱销与所述中央旋转体30可转动连接，在所述连接块上设有弧形通孔211，其使得第一风扇连接杆20A在角度变化时，其端部绕柱销转动时可在弧形通孔211内滑动。该第一风扇连接杆20A另一端端部设有U形连接头22，第一风扇连接杆20A通过其U形连接头22与风扇电机上的第一连接块111可转动连接。所述第二风扇连接杆20B为固定式连接杆，其包括两根相互平行并固定为一体的杆状体，第二风扇连接杆20B的一端固定在第一风扇连接杆20A相对侧下方的中央旋转体30外侧，其另一端固定在风扇电机11的外壳上。
如图1、图2所示，在所述第一风扇连接杆20A和第二风扇连接杆20B的自由端各连接有一个除尘风扇10A、10B，该除尘风扇10A、10B对称设置于中央旋转体的两侧。其中的除尘风扇10A的风扇连接杆与水平面之间的夹角可变换且风扇可摆动90度，另一个除尘风扇10B的风扇连接杆与水平面之间的角度固定，且风扇可在竖向平面内360度旋转，使得本装置可不留死角地进行全方位除尘。所述除尘风扇10A、10B各包括一个风扇电机11和风扇12，在所述风扇电机11外壳的两侧分别设有第一连接块111和第二连接块112，两个连接块分别用于连接风扇连接杆角度变换机构60和风扇角度变换机构70。
如图1、图2所示，为了控制除尘风扇10A在圆周方向的旋转角度，在所述第一风扇连接杆20A上连接有风扇连接杆角度变换机构60。该风扇连接杆角度变换机构60包括第二气压传动机构61、连接头62及连接套63。所述第二气压传动机构61包括第二气缸611和与气缸内的活塞连接的第二活塞杆612，其第二气缸611的一端固定到中央旋转体的竖向连接板36上，其第二活塞杆612端部设有U形连接头62，在所述风扇连接杆中部固定有连接套63，该连接套63包括套体631和与之一体的连接块632，所述套体631固定于风扇连接杆20中部，所述连接块632活动地插入所述U形连接头62内，使得第二气压传动机构61与连接套63形成活动连接。当风扇连接杆角度变换机构的第二气缸611进气时，推动气缸内的活塞及第二活塞杆612向前移动，第二活塞杆经连接套63推动风扇连接杆20以其与中央旋转体30的连接端为支点从低于水平面的位置向上转动，当第二活塞杆612运行至行程终点时，风扇连接杆20上升至水平位置，行程结束，此时，风扇连接杆20可根据预设的时间在该位置除尘一定时间后由风扇连接杆角度变换机构60带动其向下旋转。
如图1、图2所示，除了控制第一风扇连接杆20A在圆周方向的旋转角度外，本发明还设置了风扇角度变换机构70，其包括第三气压传动机构71、 第三连接块72及连接座73。第三气压传动机构71包括第三气缸711和与气缸内的活塞连接的第三活塞杆712。所述连接座73为块状体，其一端设有连接孔731，另一端呈U形，在其开口端装有销轴732，所述连接座通过其连接孔731套接固定于风扇连接杆20上。在所述第三气压传动机构的第三活塞杆712端部固定有第三连接块72，该第三连接块72呈U形，第三气压传动机构71的一端活动套接于连接座的销轴732上，另一端通过其U形的第三连接块72与除尘风扇的第二连接块112插接而形成转动连接。第三气缸711的前端设有进气口7111，其与外部气源相连接。当第三气缸未进气时，除尘风扇10A被风扇角度变换机构的第三活塞杆712拉起，此时，除尘风扇10A的风扇电机11的轴线与第三气缸711处于同一直线上。当第三气缸进气时，第三活塞杆712逐渐向外伸出，当第三活塞杆712到达最大行程时，其停止运行，除尘风扇10A通过其自身重力落下，此时，风扇电机11的轴线与水平面间的夹角接近或等于90度。通过该风扇角度变换机构70实现了除尘风扇10A的角度变换。
本发明的除尘装置的运动由控制机构80控制。如图6所示，该控制机构80为单片机，其内可定入控制程序，并可根据需要进行修改。控制程序包括设定升降机构40的升降高度、第一风扇连接杆20A的旋转角度、除尘风扇10A的旋转角度，在不同高度和不同角度运行的时间及角度变换的时间间隔等。该控制机构80设于所述中央旋转体30内的线路板81上，并通过电刷分别与所述中央旋转体30、升降机构40、进气旋转复合体50、风扇连接杆角度变换机构60及风扇角度变换机构70相连接，以控制中央旋转体30的启动或停止，升降机构40的升降，进气旋转复合体50的进气，风扇连接杆20及除尘风扇10的旋转角度。
尽管通过以上实施例对本发明进行了揭示，但本发明的保护范围并不局限于此，在不偏离本发明构思的条件下，对以上各构件所做的变形、替换等均将落入本发明的权利要求范围内。
