本发明的最佳实施方式
[0023] 下面结合附图详细描述本发明。
[0024] 图 1本发明涉及的处理盒的一部分结构示意图， 图 2是本发明涉及的处理盒的另 一部分结构示意图。
[0025] 处理盒包括粉仓 1和废粉仓 2， 所述粉仓 1和废粉仓 2可以相互结合， 如图所示， 粉仓 1包括粉仓壳体 10、 以及安装在粉仓壳体中的显影辊 11和出粉刀 12， 所述显 影辊 11和出粉刀 12接触安装， 所述显影辊 11用于承载显影剂， 并将显影剂送至 感光鼓上， 所述出粉刀 12用于调节显影剂在显影辊 11上的厚度； 所述废粉仓 2包 括废粉仓壳体 20、 以及安装在废粉仓壳体中的感光鼓 21、 充电辊 22和清洁刮刀 2 3， 所述充电辊 22和清洁刮刀 23均与感光鼓 21接触， 所述感光鼓 21用于承载静电 潜像， 充电辊 22用于在成像前为感光鼓 21的表面充上均匀的电荷， 清洁刮刀 23 用于在一个成像周期结束后刮除残留在感光鼓上的显影剂。
[0026] 为了将粉仓 1中的显影剂输送至显影辊 11上， 所述粉仓 1还包括安装在粉仓壳体 10中的送粉辊 13 (如图 3所示） ， 所述送粉辊 13与显影辊 11接触设置， 送粉辊 13 包括辊轴 130以及覆盖在辊轴圆周面上的海绵体 131， 处理盒工作吋， 所述海绵 体 131表面吸附显影剂， 并将吸附的显影剂输送至显影辊 11。
[0027] [处理盒的再生]
[0028] 在进行处理盒的再生步骤前， 一般先对处理盒表面进行清洁， 然后进行以下再 生步骤：
[0029] a.拆卸处理盒的步骤；
[0030] b.清洁粉仓壳体 10和废粉仓壳体 20的步骤；
[0031] c.向粉仓壳体 10中添加新显影剂的步骤；
[0032] d.重新组装所述处理盒的步骤。
[0033] 其中， 所述拆卸处理盒的步骤还包括将处理盒的粉仓 1和废粉仓 2分离， 并拆卸 显影辊 11、 出粉刀 12、 感光鼓 21、 充电辊 22和清洁刮刀 23; 所述重新组装处理 盒的步骤还包括重新组装显影辊 11、 出粉刀 12、 感光鼓 21、 充电辊 22和清洁刮 刀 23， 并将粉仓 1和废粉仓 2重新组装成处理盒。
[0034] 图 3是本发明所述送粉辊的整体结构示意图， 所述送粉辊包括辊轴 130以及覆盖 在辊轴的圆周面上的海绵体 131， 辊轴 130的直径为 d2， 整个送粉辊 13的直径为 d 1， 且 dl〉d2， 如果由于所述海绵体 131破损而报废掉整个送粉辊 13， 也会造成 极大的资源浪费， 尤其是金属材质的辊轴 130， 因此， 需考虑送粉辊 13的再生。
[0035] 图 4A是图 3中送粉辊 A-A方向的侧视图， 图 4B是另一种送粉辊的侧视图。
[0036] 本发明通过切削另一种送粉辊的海绵体， 使得切削后的送粉辊能够满足本发明 所述送粉辊 13的尺寸要求。 为方便描述， 所述另一种送粉辊简称为原送粉辊， 本发明所述送粉辊简称为目标送粉辊。
[0037] 如图 4B所示， 原送粉辊 14的直径为 d3， 辊轴 140的直径为 d4， 为了使得原送粉 辊 14能够满足目标送粉辊 13的参数指标， 如上所述， 通过切削原送粉辊 14的海 绵体 141， 使得切削后的送粉辊直径与目标送粉辊 13的直径相同， 具体操作步骤 为：
[0038] a.清洁原送粉辊 14的表面；
[0039] b.切削原送粉辊 14的海绵体 141， 使得切削后的送粉辊直径与目标送粉辊 13的直 径相同。
[0040] 上述操作步骤是以原送粉辊辊轴 140的直径 d4与目标送粉辊辊轴 130的直径 d2相 同为前提的， 当所述 d2< d4吋， 所述操作步骤还包括在 a步骤后进行的减小原送 粉辊辊轴 140直径的步骤； 当所述 d2〉d4吋， 所述操作步骤还包括在 a步骤后进行 的增加原送粉辊辊轴 140直径的步骤。
[0041] 所述减小原送粉辊辊轴 140直径的步骤通过切削原送粉辊辊轴 140实现。
[0042] 所述增加原送粉辊辊轴 140直径的步骤可以通过在原送粉辊辊轴 140的圆周面上 设置外接物实现， 例如可以是在圆周面上套接轴套。
[0043] [防止感光鼓和显影辊损坏的方法以及装置]
[0044] 图 5是本发明处理盒中显影辊和感光鼓之间安装隔离纸的示意图。
[0045] 如上所述， 显影辊 11用于将显影剂输送至感光鼓 21上， 因此， 当处理盒完成组 装后， 显影辊 11必定处于与感光鼓 21相对的位置， 尤其在接触式显影方式中， 显影辊 11与感光鼓 21接触设置。 处理盒从出厂到终端用户使用往往会耗费较长 吋间， 在此过程中， 不仅显影辊 11的表面会变形， 感光鼓 21的表面也会被污染 ， 从而使得打印出现问题。
[0046] 本发明还提供一种防止显影辊 11和感光鼓 21损坏的方法， 采用如下步骤： [0047] a.组装处理盒；
[0048] b.在显影辊 11和感光鼓 21之间安装隔离装置。
[0049] 如图 5所示， 所述隔离装置优选的是隔离纸 3， 当处理盒组装完毕后， 直接在显 影辊 11和感光鼓 21之间***隔离纸 3， 使得显影辊 11和感光鼓 21不直接接触， 因 而， 可有效防止因显影辊 11和感光鼓 21长吋间接触造成的打印缺陷。
[0050] 当然， 所述隔离装置并不限于隔离纸 3， 还可以是安装在处理盒两个纵向末端 的隔离销 （未示出） ， 当处理盒组装完毕后， 分别在处理盒的两个纵向末端安 装隔离销， 所述隔离销***显影辊 11和感光鼓 21之间， 使得显影辊 11和感光鼓 2 1不直接接触， 也可以有效防止显影辊 11变形以及感光鼓 21表面被污染， 从而造 成打印缺陷。
[0051] [减小粉仓中残余显影剂量的方法]
[0052] 图 6是本发明处理盒中粉仓面向废粉仓的结构示意图； 图 7是本发明处理盒中粉 仓背向废粉仓的结构示意图。
[0053] 如图 6和图 7所示， 粉仓 1的壳体包括面向废粉仓的前侧面 10a以及背向废粉仓的 后侧面 10b， 所述前侧面 10a上设置有第一检粉口 101， 后侧面 10b上设置有第二检 粉口 102， 所述第一检粉口 101与第二检粉口 102相对设置， 其工作原理是： 根据 穿过第一检粉口 101和第二检粉口 102的光线多少判断粉仓 1中显影剂的剩余量。 当粉仓 1中的显影剂较多吋， 第一检粉口 101和第二检粉口 102之间的光路完全被 显影剂阻断， 此吋， 打印机显示处理盒中的显影剂量充足； 当粉仓 1中的显影剂 逐渐被消耗掉， 第一检粉口 101和第二检粉口 102之间的光路不能再完全被显影 剂阻断， 而是有光线穿过第一检粉口 101和第二检粉口 102吋， 打印机根据透过 的光线量显示显影剂的剩余量。
[0054] 然而， 由于所述第一检粉口 101和第二检粉口 102均不是设置在粉仓 1的最底部 ， 因此， 当打印机显示处理盒中的显影剂被消耗完吋， 实际上， 位于所述检粉 口与粉仓 1的最底部之间还残留有显影剂， 也就说粉仓 1中的显影剂并没有被完 全消耗掉， 如果终端用户按照打印机的提示而更换处理盒， 势必会造成显影剂 的浪费。
[0055] 本发明还提供一种减小粉仓中残余显影剂量的方法， 具体为遮挡至少第一检粉 口 101和第二检粉口 102之一， 使得光线不能同吋穿过第一检粉口 101和第二检粉 Π 102。
[0056] 所述遮挡至少第一检粉口 101和第二检粉口 102之一的方式可以采用黑色颜料涂 覆至少第一检粉口 101和第二检粉口 102之一， 也可以采用在至少第一检粉口 101 和第二检粉口 102上安装不透光部件的方式。
采用本发明所述的再生方法， 可以有效的将已经完成一个寿命的处理盒再生， 以达到节约资源的目的。
