通常, 当可用于激光打印机的、单独的显影剂供应装置安装到激光打印机中的预定 位置时, 显影剂供应装置上的显影剂供应口与激光打印机中的显影单元上的显影剂接 收口对接, 显影剂从显影剂供应装置供应到激光打印机中的显影单元中以参与显影。
如图 1所示为现有的一种显影剂供应装置的结构示意图,显影剂供应装置 20包括: 盒体 21, 送粉部 23, 传送螺杆 50, 驱动齿轮 60, 与驱动齿轮连接的旋转轴 61, 弹性 元件 43和开关件 40.出粉部 23设置有第一显影剂供应口 25和开口 24, 开关件 40上 设置有第二显影剂供应口 30和凸起 37, 凸起 37插入到开口 24中。盒体内部容纳显影 剂 T。 旋转轴 61通过驱动齿轮组与传送螺杆 50连接。
当显影剂供应装置安装到激光打印机中前, 在弹性元件 43 的作用下, 出粉部 23 上的第一显影剂供应口 25和开关件 40上的第二显影剂供应口 30是错开的; 当显影剂 供应装置向激光打印机中安装过程中, 凸起 37受到激光打印机中相应位置上的凸起推 动, 使开关件 40克服弹性元件 43的弹力在出粉部 23中向传送螺杆 50的方向滑动, 使出粉部 23上的第一显影剂供应口 25和开关件 40上的第二显影剂供应口 30对准, 开始供应显影剂。 驱动齿轮 60接受来自激光打印机上的驱动力, 通过旋转轴、 驱动齿 轮组带动传送螺杆 50转动, 将显影剂输送到显影剂供应口。 当显影剂供应装置从激光 打印机中取出时, 施加在凸起 37上的力释放, 在弹性元件 43的弹性力的作用下, 开 关件 40向远离传送螺杆的方向运动, 使出粉部 23上的第一显影剂供应口 25和开关件 40上的第二显影剂供应口 30是错开, 断开供应显影剂。
这种显影剂供应装置控制显影剂从显影剂供应口流出的控制机构结构较复杂,导致 显影剂供应装置的工作可靠性降低, 生产成本高。 发明内容

实施例一
参见图 2, 显影剂供应装置 100包括: 盒体, 设置在盒体上的把手 126.用户通过 拿拎把手 126将显影剂供应装置安装到显影单元 180上,显影单元 180包括显影剂接收 口 188.显影剂供应装置的盒体包括显影剂仓体盖 102和显影剂仓体 108,显影剂仓体盖 102和显影剂仓体 108通过焊接的方式连接,在内部形成容纳显影剂的显影剂储存区 103 (图 3中所示)。
参见图 3A、 3B及图 4, 显影剂仓体 108的一端上设置有齿轮组 120, 用于将激光 打印机的驱动力传递到显影剂供应装置 100上。显影剂搅拌元件 109容纳于显影剂储存 区 103中, 显影剂搅拌元件 109包括搅拌元件盒体 1091和旋转轴 1092, 旋转轴 1092 一端与齿轮组 120连接驱动旋转, 搅拌元件盒体 1091将显影剂储存区 103内的显影剂 向第一传送螺杆 110的方向传送。 第一传送螺杆 110位于显影剂导向槽 1081中, 第一 传送螺杆 110的一端安装有驱动齿轮 111,驱动齿轮 111与齿轮组 120中的齿轮啮合传 递动力。 第一传送螺杆 110将显影剂搅拌元件 109传送到显影剂导向槽 1081中的显影 剂传送到显影剂供应部 1082。显影剂供应部 1082设置有显影剂供应口 1083,显影剂供 应部 1082包括内壁, 沿第一传送螺杆 110的旋转方向, 显影剂供应部的内壁包括前壁 10821和后壁 10822 (图 6), 显影剂供应口 1083位于显影剂供应部内壁的前壁 10821 和后壁 10822之间。在显影剂导向槽 1081与显影剂供应部 1082连通位置设置有带有轴 孔的支撑部 1084。柱状体的送粉轮 120安装在显影剂供应部 1082中, 送粉轮的外部结 构与显影剂供应部的内壁结构相匹配,送粉轮 120的外表面与显影剂供应部的内壁紧密 接触。送粉轮 120的一端与第一传送螺杆 110固定连接,另一端通过支架 140固定支撑 在显影剂仓体 108的侧壁上。 第一传送螺杆 110的轴端 (非齿轮端) 穿过支撑部 1084 的轴孔, 与送粉轮 120连接, 送粉轮 120与第一传送螺杆 110—起旋转。在显影剂供应 部 1082朝向搅拌元件 109 的方向上, 还设置有围墙 1085, 围墙半包围显影剂供应部 1082, 围墙 1085的一个墙壁 10851与显影剂导向槽 1081的侧壁 10811连接,另一个墙 壁 10852延伸至显影剂仓体 108的侧壁。围墙 1085的壁高大于显影剂导向槽 1081的侧 壁 10811的壁高, 即在第一传送螺杆 110的径向上, 围墙 1085的径向深度大于显影剂 导向槽 1081的径向深度。在围墙侧壁 10851与支撑部 1084之间设置有显影剂通道 1086, 连通显影剂导向槽 1081和围墙 1085的内部.当位于显影剂储存区 103内的显影剂被搅 拌元件 109传送到显影剂导向槽 1081和围墙 1085中后, 位于显影剂导向槽 1081中的 显影剂通过第一传送螺杆 110向显影剂供应部 1082传送, 显影剂导向槽内的显影剂经 过通道 1086进入到显影剂供应部 1082中。 围墙 1085可以围堵进入到显影剂供应部的 显影剂以防止其再返回到显影剂储存区 103中。 显影剂导向槽 1081、 围墙 1085和支撑 部 1084与显影剂仓体 108—体成型。
参见图 5-6, 送粉轮 120的截面为圆形, 送粉轮 120包括: 中心轴 121, 沿中心轴 径向排布的多个隔板 122和轴向封堵隔板的两个侧壁 123,隔板 122位于侧壁 123之间。 隔板的数量大于等于 4,本实施例所采用的隔板为 7个,隔板与隔板之间形成送粉槽 124, 送粉槽 124的大小均相同。 侧壁 123的径向延伸高度与隔板 122的径向延伸高度相同, 侧壁 123在轴向上封堵显影剂, 防止显影剂在轴向方向上从显影剂导向槽 1081进入到 送粉槽 124中。当显影剂由传送螺杆传送到送粉轮 120处,显影剂进入到邻近围墙 1085 的送粉槽中, 当载有显影剂的送粉槽旋转到与显影剂供应口对接的位置,送粉槽内的显 影剂从显影剂供应口 1083流出进入到显影单元的显影剂接收口 188中 (如图 2), 空的 送粉槽随着送粉轮继续旋转到可以装载显影剂的位置, 继续运载显影剂到显影剂供应 口, 即实现显影剂供应口的打开。 当显影剂供应装置处于非工作状态, 即送粉轮处于静 止时, 至少有两个送粉轮上隔板在显影剂供应部 1082的前壁 10821和后壁 10822之间 形成径向封堵, 使显影剂被隔离在显影剂供应口 1083之外, 从而实现显影剂供应口的 关闭。
参见图 7A-7C, R为送粉轮 120的旋转方向, 为清楚描述送粉轮的工作过程, 沿着 送粉轮的旋转方向 R, 将送粉轮的隔板进行数字编号为 1号隔板、 2号隔板…… 7号隔 板, 由此产生的隔板之间的送粉槽可以编号为 1-2号送粉槽、 2-3号送粉槽…… 6-7号 送粉槽。当显影剂供应装置安装到激光打印机的显影单元中开始工作时,显影剂储存区 103内的显影剂经由搅拌元件 109和第一传送螺杆 110传送至送粉轮 120所在的显影剂 供应部 1082处, 此时显影剂进入到 1-2号送粉槽、 2-3号送粉槽和 3-4号送粉槽中; 4-5号送粉槽、 5-6号送粉槽、 6-7号送粉槽和 7-1号送粉槽中为空; 如图 7A。 随着送 粉轮的继续旋转, 当 3-4号送粉槽与显影剂供应口 1083对接的时候, 其中的显影剂从 3-4号送粉槽中卸载,通过显影剂供应口 1083流入显影单元的显影剂接收口 188,同时, 7-1号送粉槽及 6-7号送粉槽开始装载显影剂, 如图 7B。 送粉轮继续旋转, 2-3号送粉 槽与显影剂供应口 1083对接, 显影剂从 2-3号送粉槽中卸载, 3-4号送粉槽空, 开始 进入到下一个装载显影剂的周期。 随着送粉轮的旋转, 送粉槽装载、 卸载显影剂, 从而 实现显影剂供应装置向显影单元供应显影剂。 当送粉轮停止转动时, 位于前壁 10821 侧的任意一个隔板可以与位于后壁 10822 的任意一个隔板形成对显影剂供应部的径向 封堵,处于非显影剂供应口的送粉槽中的显影剂被保留在相应的送粉槽中,实现显影剂 供应装置停止向显影单元供应显影剂, 例如, 图 7B中, 若送粉轮停止转动, 3-4号送 粉槽中显影剂已通过显影剂供应口 1083流入到显影单元的显影剂接收口 188中后, 位 于前壁的 4号、 5号及 6号隔板中的任意一个隔板可以与位于后壁 10822的 2号和 3号 隔板中的任意一个隔板形成径向封堵, 处于送粉槽中的显影剂不会流向显影剂供应口 1083。
参见图 8, 为进一步提高向显影剂供应部的显影剂传送量, 显影剂供应装置还可以 在第一传送螺杆 110的并排位置设置第二传送螺杆 210,第二传送螺杆 210安装在第二 显影剂导向槽 220中。第二传送螺杆 210的一端安装有驱动齿轮 230, 驱动齿轮 230由 齿轮组 120驱动,驱动齿轮 230与第一传送螺杆 110的驱动齿轮 111啮合驱动第一传送 螺杆 110旋转。第一传送螺杆 110与第二传送螺杆 210的螺纹方向相反。通过这种双传 送螺杆的方式, 可以大大提到向显影剂供应部及送粉轮处的显影剂供应量。
第一传送螺杆的轴端与支撑部 1084的轴孔 10841配合, 第一传送螺杆在高速旋转 过程中, 显影剂很容易进入到第一传送螺杆的轴端与支撑部 1084的轴孔 10841之间的 间隙中, 第一传送螺杆的轴端与支撑部 1084的轴孔 10841配合位置一直 "浸"在显影 剂中,因为显影剂中含有添加剂,位于第一传送螺杆的轴端与支撑部 1084的轴孔 10841 之间的间隙中的显影剂添加剂受力摩擦很容易融化,第一传送螺杆的轴端和支撑部的轴 孔 10841被融化的显影剂添加剂粘在一起,导致第一传送螺杆"卡死"而无法正常工作。 为解决此问题, 参见图 17, 在轴孔 10841的径向上设置多个凹槽 10842, 以减少第一传 送螺杆的轴端与支撑部的轴孔的接触面积,同时也为进入到间隙中的显影剂提供活动空 间, 从而有效地解决上述传送螺杆 "卡死" 的问题。 实施例二
本实施仅对于实施例一不同的结构进行描述说明, 其他与实施例一相同的结构不 再赘述。
参见图 9-10, 传送螺杆 310位于显影剂导向槽 320中, 一端通过驱动齿轮 111与 齿轮组 120连接接收旋转动力,另一端通过支架 340被支撑在显影剂供应装置的盒体上。 送粉轮 330设置在显影剂供应部 2082中, 一端通过轴孔配合的方式可旋转地支撑在显 影剂供应部的侧壁上,另一端也通过支架 340被支撑在显影剂供应装置的盒体上。传送 螺杆 310和送粉轮 330在支架 340侧的一端各安装有传动齿轮 350和 360,传动齿轮 350 和 360啮合传递动力。 齿轮组 120通过传动齿轮 111将旋转动力传递给传送螺杆 310, 传送螺杆 310再带动送粉轮 330旋转。
参见图 11, 送粉轮 330包括: 中心轴 331和沿中心轴径向排布的多个隔板 332, 隔板与隔板之间形成送粉槽 334.中心轴 331可作为送粉轮 330的旋转轴, 一端与显影 剂供应部的侧壁连接, 一端由支架 340支撑且安装有传动齿轮 360.隔板 332的一侧端 部与显影剂供应部的侧壁抵接,另一侧的端部与支架 340抵接,防止显影剂在送粉轮不 旋转时从送粉轮的轴向上泄漏。
参见图 12, 显影剂供应部 2082包括上层 20821和下层 20822。 送粉轮 330的隔板 332的外圆周与下层 20822的内壁抵接, 显影剂供应口 20823设置在下层 20822上。 参见图 13, 在显影剂供应部 2082 的径向方向上, 送粉轮 330位于显影剂供应口 20823与传送螺杆 310之间。显影剂先由传送螺杆 310传送至显影剂供应部的上层 20821 处,显影剂自由下落到送粉轮 330的送粉槽 334中,载有显影剂的送粉槽旋转至与显影 剂供应口对接,位于送粉槽中的显影剂流出显影剂供应口。送粉轮 330输送显影剂的过 程, 请参考实施例一。
本实施例中, 送粉轮的隔板两端也可以设置如实施例一中所述的侧壁。
实施例一中所述的围墙结构也适用于本实施例。
本实施例的传送螺杆与送粉轮在显影剂供应部径向方向上错开设置的结构, 相比 于实施例一中送粉螺杆与送粉轮同轴的结构而言,显影剂可以直接从传送螺杆传送给送 粉轮, 显影剂传送效率更高。 实施例三
实施例一和实施例二中的送粉轮的结构存在一个技术问题, 就是为保证送粉轮与 显影剂供应部之间的密封,送粉轮的隔板必须与显影剂供应部的内壁接触,且接触的越 紧密, 密封性越好; 但是接触越紧密, 送粉轮与显影剂供应部之间的摩擦越大, 导致送 粉轮的旋转扭矩变大。为解决上述问题,本实施例是对实施例一和实施例二的送粉轮结 构进行优化的一种方案,为突出本实施例与实施例一和实施例二不同的技术特征,对与 实施例一和实施例二相同的技术特征不再重复描述。
参见图 14-15, 本实施例的送粉轮 420隔板采用 4个, 隔板 500上粘贴有可弹性变 形的密封片 400,密封片 400在送粉轮 420的径向方向上的延伸长度大于显影剂供应部 1082 ( 2082 ) 的内径; 隔板 500的外圆周不与显影剂供应部 1082 ( 2082 ) 的内壁接触。 当送粉轮在显影剂供应部中旋转时,密封片与显影剂供应部的内壁接触,并发生弹性弯 曲,从而实现当送粉轮不转动时送粉轮与显影剂供应部之间的径向密封。通过上述结构, 不仅可以降低送粉轮的旋转扭矩, 还大大提高了送粉轮与显影剂供应部之间的密封性。
密封片 400可采用硬度较小的 RET片等。 实施例四
本实施例提供另外一种不同于实施例三、 解决实施例三所述的技术问题。 参见图 16, 显影剂供应部 1082 ( 2082 ) 与送粉轮 120 ( 230 ) 之间设置弹性密封件 600和可弯 曲密封件 700。弹性密封件 600粘贴在显影剂供应部的内壁上, 弹性密封件可采用通孔 海绵、 P0R0棉等。 可弯曲密封件 700位于弹性密封件 600与送粉轮之间, 可弯曲密封 件 700粘贴在弹性密封件 600上,可弯曲密封件 700可采用具有光滑表面摩擦系数较小 的 PRT片等。送粉轮的外圆周与可弯曲密封件 700的表面抵接。弹性密封件 600主要是 密封送粉轮与显影剂供应部,可弯曲密封件 700主要用于减小送粉轮的旋转扭矩。通过 设置上述密封件,不仅可以增强送粉轮与显影剂供应部之间的密封性, 同时也可以减小 送粉轮的旋转扭矩。
因为送粉轮在工作时高速、 不停的旋转, 为了防止上述密封件受到送粉轮旋转的 影响而脱落或者移位,上述密封件在送粉轮旋转方向 R的最上游的端部 610和 710固定 在显影剂供应部的固定部 1087上。 因为可弯曲密封件 700具有一定硬度, 如果可弯曲 密封件 700与弹性密封件 600之间贴合的不好,可影响送粉轮的密封性及扭矩,所以可 弯曲密封件 700最好是只有端部 710固定在固定部 1087上, 其余部分不与弹性密封件 600固定, 这样, 可弯曲密封件 700可以在送粉轮旋转过程中, 动态调整与弹性密封 件之间的贴合效果,从而使弹性密封件 600和可弯曲密封件 700的密封效果及降低扭矩 的效果更好。
本发明中的隔板数量至少为 3个, 实际应用的时候可以根据实际情况进行选择。
