在图1至图3所示的示例性实施方式中，所述旋转体1-2为导电金属球体。本发明不限于此，所述旋转体1-2也可以是由其他导电材料制成的球体。在可选的实施方式中，所述旋转体还可以为导电圆柱体或导电圆筒体。
【第二实施方式】
图4示意性示出了本发明第二实施方式的静电纺丝设备。参阅图4，除了使用导电圆柱体1-4替换图1至图3所示的旋转体1-2外，本实施方式的静电纺丝设备的结构与图1至图3所示的静电纺丝设备的结构相同。在图4所示的静电纺丝设备中，在环形外罩1-1内设置转轴，并使所述导电圆柱体1-4能够围绕所述转轴自由转动，从而，当所述环形外罩1-1在电动机5的驱动下转动时，所述转动带动所述导电圆柱体1-4围绕各自的转轴转动且无法脱离所述环形外罩1-1的孔洞。当所述导电圆柱体1-4被所述环形外罩1-1带动而在所述孔洞中转动时，所述导电圆柱体1-4的表面会从所述环形空腔沾满纺丝液。在高压电源10产生的静电场中，所有暴露在所述环形外罩1-1表面的旋转体1-2，其表面沾上的纺丝液在电场力的作用下，一起被拉伸成射流，溶剂挥发，最后固化沉积到环形接收装置9上，形成纳米纤维。在可选的实施方式中，可以采用导电圆筒体替换所述导电圆柱体1-4。
在图4所示的实施方式中，通过设置转轴来允许。在可选的实施方式中，当然也可以采用本领域已知的结构，只要能够实现导电圆柱体1-4自由转动的同时不会脱离所述环形外罩1-1的孔洞即可。
在以上示例性实施方式中，多个旋转体在所述环形外罩的外周面的第一高度环绕所述环形外罩布置。换句话说，多个旋转体在所述环形外罩的外周面的同一高度环绕所述环形外罩布置。
在可选的实施方式中，所述多个旋转体中有一部分在所述环形外罩的外周面的第一高度环绕所述环形外罩布置，还有一部分在所述环形外罩的外周面的第二高度环绕所述环形外罩布置，所述第一高度与所述第二高度不同。换句话说，所述多个旋转体在所述环形外罩的外周面的高度方向设置为至少两层。在一些实施方式中，位于所述第一高度的旋转体与位于所述第二高度的旋转体在圆周方向上彼此错位设置，也就是说，相邻层的旋转体彼此错开设置。从而，可以进一步提高纳米纤维的产量。当然，在其他实施方式中，相邻层的旋转体可以彼此对齐，便于设备制造，提高设备的生成效率。
在本发明的一些实施方式中，位于所述环形外罩的外周面上的同一高度(或同一层)的多个旋转体中相邻旋转体之间的间隔可以相等，也可以不相等。例如，在图1至图4所示的实施方式中，多个旋转体在环形外罩的周向上间隔相等，即均匀布置。
在本发明的一些实施方式中，所述多个旋转体离所述环形接收装置的接收纳米纤维的表面的距离相等。从而，使得射流尽可能受到相同条件的牵伸，从而提高纳米纤维的直径的分布均匀性和形貌结构均一性。
在本发明的一些实施方式中，所述回转式纺丝发生装置的旋转中心与所述环形接收装置的圆心重合。这样也可以使得射流尽可能受到相同条件的牵伸，从而提高纳米纤维的直径的分布均匀性和形貌结构均一性。
在一些实施方式中，所述回转式纺丝发生装置的转速可调，例如，通过调节电动机5的输入电流来调节环形外罩1-1的转速，由此可以调节纤维的拉伸和取向排列。
在本发明的示例性实施方式中，供给纺丝液的流量泵通过包含螺旋进料杆的通道与所述环形空腔连接并流体连通。在可选的实施方式中，所述供液装置包括流量泵，所述流量泵通过连接管与所述环形空腔相连，从而直接向所述环形空腔供给纺丝液。
此外，在可选的实施方式中，不是必须将所述回转式纺丝发生装置设置在供液装置的上方，可以将所述回转式纺丝发生装置设置在固定铁架台6的底座上，例如，可以将电动机5设置在固定铁架台6的底座上，此时，供液装置可以设置所述回转式纺丝发生装置的上方，并且无需螺旋进料杆即可向所述回转式纺丝发生装置供给纺丝液。可选地，流量泵可通过连接管直接向所述回转式纺丝发生装置供给纺丝液。
根据本发明第一、第二实施方式可知，本发明的回转式纺丝发生装置为一种公转自转装置，其环形外罩带动各旋转体围绕环形外壳的旋转中心公转的同时各旋转体围绕自己的圆心发生自转，所述自转使得相应的旋转体从环形空腔内沾满纺丝液，这种公转自转的运动方式使得各旋转体能够充分蘸取纺丝液的同时不会发生堵塞，并且，通过各个旋转体表面来实现喷丝操作，可以达到自由液面纺丝装置相同的效果，但不会导致纺丝液内有机溶剂的快速挥发，避免出现纳米纤维膜的形貌和性能下降。因此，采用本发明的回转式纺丝发生装置不仅能够提高纳米纤维的产量，还能提高纳米纤维的质量。
此外，在本发明的可选实施方式中，所述环形接收装置构造成能够与所述回转式纺丝发生装置同向或反向旋转。例如，所述环形接收装置的外周具有齿以用作蜗轮，与电动机连接的蜗杆与所述齿啮合，由此通过电动机驱动所述环形接收装置正转或反转。并且，可以通过调节输入电动机的电流对所述环形接收装置的转速进行调节。通过调节所述环形接收装置与所述回转式纺丝发生装置的转动方向以及相对转速，可以调节纤维的拉伸和取向排列。
在示例性实施方式中，可通过利用所述环形接收装置与所述回转式纺丝发生装置反向转动来达到纤维的拉伸以及取向排列。本发明不限于此，即使所述环形接收装置与所述回转式纺丝发生装置同向转动，也可以通过调节二者的相对转速来调节纤维的拉伸和取向排列。
【第三实施方式】
图5示出了根据本发明的第三实施方式的静电纺丝设备的概要结构。在本实施方式中，所述静电纺丝设备包括：高压电源510；圆盘形接收装置520，其与所述高压电源510的负极电连接；回转式纺丝发生装置530，其位于圆盘形接收装置520的下方，并与所述高压电源510的正极电连接；以及供液装置540，例如流量泵，其与所述回转式纺丝发生装置530流体连通，以向所述回转式纺丝发生装置530供给纺丝液。在本实施方式中，所述回转式纺丝发生装置530设置在底座550上，所述圆盘形接收装置520经由支撑结构(未示出)支撑在所述回转式纺丝发生装置530的上方。
在本实施方式中，所述回转式纺丝发生装置530包括：环形供液池531，其与所述供液装置540流体连通，以接收并容纳所述纺丝液；多个旋转体532，所述多个旋转体532中的每一个至少部分位于所述环形供液池531中，并且设置成可沿着所述环形供液池531移动的同时自转。在一些实施方式中，如图6所示，所述环形供液池531包括：环形槽531-1，其界定出用于接收并容纳纺丝液的环形空腔，所述环形空腔的上部开口；环形盖板531-2，其用于盖住所述环形槽的上部开口并且能够相对所述环形槽531-1转动，所述环形盖板531-2具有多个孔洞，其中，所述多个旋转体532分别设置在所述多个孔洞中且至少部分暴露在所述孔洞外，并且所述旋转体适于在所述环形盖板531-2的转动的带动下在所述孔洞中转动。如图7所示，该图示出了环形供液池的一部分，其中所述环形槽531-1的开口端的侧壁设有卡槽，所述环形盖板531-2卡在所述卡槽中，并且能够沿着所述卡凹槽移动。例如，可以通过驱动组件来驱动所述环形盖板531-2移动。返回参阅图6，在示例性实施方式中，所述驱动组件包括电动机560和传动机构570。所述传动机构570与所述电动机的输出轴561连接，例如，所述传动机构570包括旋转轴，所述旋转轴的一端连接输出轴561，另一端设有与环形盖板531-2连接的连接件。从而，电动机560的转动经由输出轴561和传动机构570传递给所述环形盖板531-2，使得所述环形盖板531-2沿着环形槽531-1上的卡槽移动(即转动)，进而带动环形盖板531-2的各孔洞中的旋转体532围绕所述环形槽531-1的圆心(即环形供液池531的圆心)公转，同时所述旋转体532在相应的孔洞中会自转。这样，所述旋转体的表面部分或全部会沾上纺丝液，在所述高压电源510产生的静电场中，所述纺丝液在电场力的作用下被拉伸成射流，所述射流伴随溶剂挥发而形成纳米纤维并沉积到所述圆盘形接收装置520上。
在一些实施方式中，所述圆盘形接收装置520的圆心与所述环形供液池531的圆心同轴。可选的，所述圆盘形接收装置520的直径大于或等于所述环形盖板531-2的外径。这样，可以确保所述接收装置能够接收所有的纳米纤维。
在一些实施方式中，如图8所示，所述多个旋转体532在所述环形盖板531-2上排列成一圈。在其他实施方式中，所述多个旋转体在所述环形盖板上可排列成至少两圈。并且，在一些实施方式中，位于一圈的旋转体与位于另一圈的旋转体彼此错位设置。可选的，位于一圈的旋转体与位于另一圈的旋转体可径向对齐设置。在一些实施方式中，在所述环形盖板上，位于同一圈的多个旋转体中相邻旋转体之间的间隔可相等。在一些实施方式中，所述多个旋转体可以在所述环形盖板上随机分布。
在一些实施方式中，所述多个旋转体532离所述圆盘形接收装置520的接收所述纳米纤维的表面的距离相等。从而，使得射流尽可能受到相同条件的牵伸，从而提高纳米纤维的直径的分布均匀性和形貌结构均一性。
在一些实施方式中，所述圆盘形接收装置520构造成能够与所述环形盖板531-2同向或反向旋转。通过调节所述圆盘形接收装置与所述环形盖板的转动方向以及相对转速，可以调节纤维的拉伸和取向排列。

在一些实施方式中，如图10所示，所述圆盘形盖板931-2底部设有环形卡槽，所述圆形供液池931-1的开口端嵌入所述环形卡槽中，并且所述圆盘形盖板931-2能够相对于所述圆形供液池931-1转动。例如，可以通过驱动组件来驱动所述圆盘形盖板932-1转动。在一些实施方式中，所述驱动组件可以包括电动机960和传动机构970，所述传动机构970可以包括与电动机960的输出轴961连接的齿轮。所述圆形盖板931-2的周侧具有与所述齿轮啮合的齿，由此，所述电动机960的转动可以经由输出轴961和传动机构970的齿轮传递至所述圆形盖板931-2，使得圆形盖板931-2沿着圆形供液池931-1的圆周转动。所述圆形盖板931-2的转动带动其各孔洞中的旋转体932围绕所述圆形供液池931-1的圆心公转，同时所述旋转体932在相应的孔洞中会自转。这样，所述旋转体的表面部分或全部会沾上纺丝液，在所述高压电源910产生的静电场中，所述纺丝液在电场力的作用下被拉伸成射流，所述射流伴随溶剂挥发而形成纳米纤维并沉积到所述圆盘形接收装置920上。
在一些实施方式中，所述圆盘形接收装置920的圆心与所述圆形供液池931-1的圆心同轴。并且，所述圆盘形接收装置920的直径大于或等于所述圆形盖板931-2的外径。从而，确保所述接收装置对纳米纤维的接收。
在一些实施方式中，如图11所示，所述多个旋转体932在所述圆形盖板931-2上排列成一圈。在其他实施方式中，所述多个旋转体在所述圆形盖板上可排列成至少两圈。并且，在一些实施方式中，位于一圈的旋转体与位于另一圈的旋转体彼此错位设置。可选的，位于一圈的旋转体与位于另一圈的旋转体可径向对齐设置。在一些实施方式中，在所述环形盖板上，位于同一圈的多个旋转体中相邻旋转体之间的间隔可相等。在一些实施方式中，所述多个旋转体可以在所述圆形盖板上随机分布。
在一些实施方式中，所述多个旋转体932离所述圆盘形接收装置920的接收所述纳米纤维的表面的距离相等。从而，使得射流尽可能受到相同条件的牵伸，从而提高纳米纤维的直径的分布均匀性和形貌结构均一性。
在一些实施方式中，所述圆盘形接收装置920构造成能够与所述圆形盖板931-2同向或反向旋转。通过调节所述圆盘形接收装置与所述环形盖板的转动方向以及相对转速，可以调节纤维的拉伸和取向排列。
在本发明的上述第一至第三实施方式中，所述多个旋转体围绕所述供液池的圆心公转的同时自转。在其他实施方式中，所述多个旋转体可以围绕保持旋转体的保持件的圆心公转的同时在所述保持件中自转，例如，在上述实施方式中，具有安装旋转体的孔洞的环形外罩、环形盖板、圆形盖板可以作为所述保持件的例子。
本领技术人员应当理解，以上所公开的仅为本发明的实施方式而已，当然不能以此来限定本发明请求专利保护的权利范围，依本发明实施方式所作的等同变化，仍属本发明之权利要求所涵盖的范围。例如，在本发明的第三、第四实施方式中，虽然以导电球体作为旋转体对本发明进行了说明，但是，应当理解，类似于第二实施方式，所述旋转体还可以实施为导电圆柱体或导电圆筒体，或所述旋转体可以由导电球体、导电圆柱体、以及导电圆筒体中的至少两种的组合来实施。
