其中 ，所述存储卷筒的中心空腔一端开口 ，用于动力电机的插入安装， 另一端均匀设有至少两片空气扰动叶片，该空气扰动叶片由存储卷筒外壁 向轴心延伸，并于轴心附近形成动力电机支撑架，该空气扰动叶片之间形 成空隙保证在存储卷筒转动时驱使存储卷筒的内外空气进行交换。
优选的，所述空气扰动叶片为 4片，其均匀分布于存储卷筒的端面上。 优选的，所述空气扰动叶片沿圆周方向呈不规则的 Ζ字型走向。
优选的 ，所述薄卷带为两条，对应的回收卷筒为两个，两条薄卷带分 别卷绕在回收卷筒上，另一端层叠固定于存储卷筒外表面上，两条薄卷带 在回收卷筒与存储卷筒之间的部分形成夹持状态。
该薄片介质暂存装置与现有技术对比分析具有如下优点：
该薄片介质暂存装置的存储卷筒设计有主动散热式叶片，该设计结构 简单，实现在不增加零件的基础上解决现有问题，而且并不需要增加装置 的结构空间 ，有利于小型化设置。 附图说明

其中两件薄卷带 102足够长度，其一端分别安装在两个回收卷筒 101 上，另一端分别绕转两件薄卷带导向轴 103后共同安装在存储卷筒 201上， 薄卷带 102的剩余长度绕卷储存在回收卷筒 101上。
参阅图 3和图 4所示，该存储卷筒 201的中心空腔一端开口 ，该存储 卷筒 201 固定安装在动力电机 202 的第一动力输出轴上，并且存储卷筒 201 转动覆盖在动力电机 202 表面；另一端均匀设有四片空气扰动叶片 302 ,该空气扰动叶片 302由存储卷筒外壁 303向轴心延伸，并于轴心附 近形成动力电机支撑架 301 ,该空气扰动叶片 302沿圆周方向呈不规则的 Z字型走向 ，相邻动气扰动叶片 302之间形成空隙保证在存储卷筒 201转 动时驱使存储卷筒 201的内外空气进行交换，该空隙形成驱动风口 203。
参阅图 5进一步说明该存储卷筒转动时的风道情况，当存储卷筒 201 由动力电机 202驱动旋转时，存储卷筒 201上的空气扰动叶片 302启动空 气流动，空气通过动力电机 202表面与存储卷筒 201内表面之间形成的散 热通道 204 ,带走电机表面的热量。 存储卷筒 201驱动风口 203处的空气 流动速度为 Vk ,动力电机 202表面散热通道 204处的空气流动速度为 Vr , 结合图 5 ,存储卷筒 201的内部横截面积示意图 ，有存储卷筒 201内部横 截面积 Si , 电机支撑架 301横截面积 S2 ,动力电机横截面积 S3 , 由于动 力电机横截面宽度 d2 >电机支撑架 301 的宽度 ,故得 S3 > S2。 根据图 示，存储卷筒 201驱动风口 203的面积 Sk= Si - S2 ,散热通道 204的面 积 Sr= Si - S3 ,所以驱动风口 203的面积 Sk与热通道 204的面积 Sr的关 系是： Sk > Sr。 即热通道 204的风速 Vr与驱动风口 203的风速 Vk的关系 满足： Vr= Vkx(Sk/Sr) > Vko 驱动风口 203处形成的气流在经过散热通道 204时因通道截面变小，气体流动速度会变快，电机表面的热量散失加快。
参阅图 7和图 8 ,进一步说明该存储卷筒 201正反转动时的空气交换 方向 ，本实施例是以动力电机 202正向转动时从散热通道内抽风，因此该 空气扰动叶片 302的倾斜方向的正向。当然根据空气扰动叶片 302倾斜方 向不同，其设置可以是正向 ，也可以是反向 ，均可以实现本发明的目的。
结合图 1至图 8进一步说明该薄片介质暂存装置在工作时的动力电机 散热过程，当薄片介质 100被送入该薄片介质暂存装置时，两件薄卷带导 向轴 103和两件绕卷薄卷带 102间形成的薄片入口接纳被送入的薄片介质 100，动力电机 202驱动存储卷筒 201和大传动轮 105大传动轮作正向转 动，大传动轮 105通过传动带 106带动两件小传动轮 104作正向转动，两 件小传动轮 104又分别通过两件小卷筒转轴 108带动两件回收卷筒 101 作正向转动，两件回收卷筒 101逐步释放出预先储存在其上的两件薄卷带 102将其内夹持的薄片介质卷绕在存储卷筒 201上完成薄片介质的存储过 程。在该过程中当存储卷筒 201转动时存储卷筒 201—端的空气扰动叶片 302绕动力电机的第一动力输出轴转动，由于该空气扰动叶片的倾斜设置， 导致其转动时其斜面撞击空气粒子，令气体粒子加速运动，并且改变运动 方向 ，从而形成从散热风道 204向驱动风口 203流动的气流，由于该气流 的形成导致散热风道 204内由于动力电机 202的工作而发出的热量被与其 接触的空气带出而实现动力电机的快速散热目的。 反之，当动力电机 202反转时，驱动存储卷筒 201 和大传动轮 105 作反向转动，两件薄卷带 102夹持薄片介质 100从存储卷筒 201绕转退出 ， 两件回收卷筒 101逐步回收薄卷带 102 ,将被夹持的薄片介质逐一放出 ， 完成暂时存储在存储卷筒 201上的薄片介质的送出功能。在该过程中当存 储卷筒 201反向转动时存储卷筒 201—端的空气扰动叶片 302—起绕动力 电机的第一动力输出轴转动， 由于该空气扰动叶片的倾斜设置，导致其转 动时斜置的斜面撞击空气粒子，令气体粒子加速运动，并且改变运动方向 ， 从而形成从驱动风口 203向散热风道 204流动的气流，由于该气流的形成 导致散热风道 204内由于动力电机 202的工作而发出的热量被与其接触的 流动空气带出而实现动力电机的快速散热目的。
另外，由于空气扰动叶片 302卷筒叶片为倾斜设置，且相邻两个空气 扰动叶片 302卷筒叶片之间留有通气空间 ，即使动力电机停止旋转时，即 存储卷筒 201不再转动，其内部由于动力电机 202工作过程中散发的热量 也可以由热对流方式从这些通气空间散失，加快动力电机自然降温。
以上仅是本发明的优选实施方式，应当指出的是，上述优选实施方式 不应视为对本发明的限制，本发明的保护范围应当以权利要求所限定的范 围为准。 对于本技术领域的普通技术人员来说，在不脱离本发明的精神和 范围内 ，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的 保护范围。
