Description

处理盒 【技术领域】
本发明涉及一种用于成像设备的新型处理盒。
【背景技术】
电子照相成像设备的例子包括复印机、打印机、传真机、一体机等以及其类似物。通常，该类成像设备设有供安装处理盒的腔室，处理盒可拆卸地安装在该类成像设备的腔室中。在处理盒安装至成像设备的腔室内后，处理盒至少在两个方向上与成像设备的腔室是弹性抵接的，比如在安装方向上或在与安装方向垂直的方向上，这使处理盒在安装或拆卸过程中会有一定的自由活动空间。在成像设备内还设有旋转力输出头。
现有一种成像设备，其旋转力输出头大致呈柱状，可沿其自身的旋转轴旋转，在垂直于其旋转轴位置上，有对称设置的两个输出突起。与该种成像设备相适配的处理盒的一端设有驱动力接收组件。驱动力接收组件设有旋转力接收部，该旋转力接收部设有与旋转力输出头侧的输出突起相联接的凸爪。一般情况下，在处理盒取出方向上，旋转力接收部的凸爪与旋转力输出头的输出突起具有部分重叠干涉距离，在处理盒的装卸过程其会造成一定的干扰。现有技术中，HP/CANON厂家采用万向节结构的驱动力接收组件，其能在处理盒卸载过程中实现与旋转力输出头的无干涉分离，但是生产成本较高；另外，兼容厂家有采用可轴向伸缩的驱动力接收组件，亦有采用带十字滑槽的驱动力接收组件，但该两种方式均存在着驱动力接收组件与成像设备侧的旋转力输出头在一些角度位置发生卡顿而难以取出的情况，强行取出会使驱动力接收组件与旋转力输出头的联接部分产生磨损或损坏，严重影响处理盒及成像设备的使用寿命。

以下结合附图对本发明的具体实施方式作进一步详细地说明。
【具体实施方式】
实施例1
如图1、图3所示，处理盒100包括有盒体1，盒体1内安装有感光鼓2、充电辊(未示出)、显影辊(未示出)、送粉辊(未示出)等旋转件。本实施例中，感光鼓2可绕自身的旋转轴线L1旋转。本实施例处理盒100与现有技术相同的部分不再赘述，以下主要针对本实施例处理盒100与现有技术的不同之处进行说明。在盒体1一端还设有驱动力接收组件3、轮毂4、端盖5和轴承板6。其中，驱动力接收组件3可从成像设备中的旋转力输出 头301接收驱动力，并将驱动力传递给感光鼓2等旋转件，使旋转件旋转；轮毂4装设于感光鼓2的一端并与感光鼓2同轴。
结合参考图2至图4、图7，驱动力接收组件3包括旋转力接收件31、位置调整机构32、推杆33、第一螺旋弹簧34、离合件35和偏压弹簧36。其中旋转力接收件31设有旋转力接收部311、旋转力传递部312和连接部313。
旋转力接收部311位于旋转力接收件31的一端，其端部设有对称的两个凸爪3111，凸爪3111可与成像设备300的旋转力输出头301的输出突起3011相互联结，进而接受来自成像设备300的旋转力。旋转力传递部312与离合件35联接，以将旋转力传递至感光鼓。旋转力传递部312的其中一部分大致呈扁长方体结构。连接部313位于旋转力接收部311和旋转力传递部312之间，用以连接旋转力接收部311和旋转力传递部312，其上设有椭圆形支撑部3131。
位置调整机构32包括从动部321、筒状件322和施力部331，其中筒状件322和施力部331构成本实施例位置调整机构32的操作组件。本实施例中，从动部321为设置在旋转力接收件31的连接部313的圆周外壁上的突筋，本实施例中突筋有两条。每条突筋均具有第一接触面3211和呈弧形的第二接触面3212。筒状件322套设在旋转力接收件31的连接部313的外侧，安装完成后，从动部321位于筒状件322的内部。在筒状件322的内侧设有弧形状的悬臂3221，本实施例中悬臂3221为弹性臂，从筒状件322的内壁沿与筒状件322的轴向相交叉的方向伸出。悬臂3221的自由端具有可与第一接触面3211抵接的第一端面32211和可与第二接触面3212滑动接触的第二端面32212。在筒状件322的圆周外壁上设有受力部3222，受力部3222可以是一个或多个凹槽，也可以是一个或多个凸起，本实施例中受力部3222呈齿状，在筒状件322外壁沿圆周方向分布。可以沿圆周一圈布满，亦可以是局部，本实施例中仅在圆周方向上局部设置。
结合参考图1、图2、图4、图5和图7，推杆33安装在盒体的端部，位于端盖5的内侧,其长度方向垂直于感光鼓2的轴线L1。在端盖5上设有第一通孔51，推杆33的长度方向的一端可 从第一通孔51穿过。施力部331设在推杆33的靠近旋转力接收件31一端，呈可与受力部3222相啮合的凸起或凹槽。本实施例中施力部331呈与受力部3222相啮合的齿状。推杆33上还设有受力面332、第一凸块333。在垂直于感光鼓2的轴线L1的方向上，受力面332位于端盖5的外侧，其可接收来自外部的推压力。本实施例中，外部的推压力来自成像设备300的门盖302的压迫块3021。当关闭成像设备300的门盖302时，门盖302的压迫块3021抵压受力面332，使推杆33相对于通孔51沿W方向移动。第一螺旋弹簧34套设在推杆33上，其一端抵压在推杆33上，另一端抵压在端盖5上，第一螺旋弹簧34可对推杆33施加弹性力。在打开成像设备的门盖302时，推杆33失去外部的推压力，在第一螺旋弹簧34的弹力作用下，推杆33沿与W方向相反的方向移动至初始位置。在推杆33沿W方向移动时，施力部331可向受力部3222施加旋转力，从而使筒状件322沿a方向转动一定角度。此种情况下，当悬臂3221的端部碰到从动部321时，悬臂3221的第二端面32212与从动部321的第二接触面3212进行滑动接触，与此同时第二接触面3212抵压第二端面32212使悬臂3221发生弹性变形，进而使第二端面32212滑过第二接触面3212，此时即使筒状件322旋转，旋转力接收件31亦不发生旋转。当推杆33在第一螺旋弹簧34的弹力作用下沿与W方向相反方向移动时，筒状件322沿与方向a相反方向旋转，悬臂3221的第一端面32211抵接在从动部321的第一接触面3211上，此时筒状件322旋转同时将带动旋转力接收件31沿与方向a相反方向预设位置旋转。
参考图2、图6，轴承板6上设有第二通孔61和轴承孔62，在靠近轮毂4的一侧设有第一凸柱63和第二凸柱64。
如图2、图3、图4、图6、图8b所示，偏压弹簧36有两个，分别安装在轴承板6上的第一凸柱63和第二凸柱64上。每个偏压弹簧36都设有两个自由端，一自由端抵压在旋转力接收件31的支撑部3131的侧面上，另一端抵压在轴承板6的第一凸柱63或第二凸柱64上；在处理盒处于非工作状态下，偏压弹簧36的一自由端对旋转力接收件31上的椭圆形支撑部3131的侧面施加弹性力，由于扭矩的作用，可使得旋转力接收件31旋转到脱机的位置，达到辅助位置调整机构32定位的效果。
参考图8b，轮毂4设有腔室41，腔室41的底部设有沿轴线L1向轴承板6方向伸出的带斜面的第一凸部42。
结合参考图2、图5、图6、图8a和图8b，离合件35包括离合滑块351、离合传动件352和第二螺旋弹簧353。离合传动件352装设于轮毂4腔室41内，与轮毂4、感光鼓同轴。离合传动件352设有可供旋转力传递部312穿过的第三通孔3521和可与轮毂4的第一凸部42在轴线L1方向上相互啮合的第二凸部3522。在第二凸部3522与轮毂4的第一凸部42在轴线L1方向上相互啮合时，离合传动件352转动时可将旋转力传递给轮毂4。第二螺旋弹簧353安装在离合传动件352和轮毂4之间，可在轴线L1方向上对离合传动件352施加弹力。离合滑块351在轴线L1方向上靠近轴承板6一端设有第二凸块3511和第三凸块3512，第二凸块3511和第三凸块3512可分别穿过轴承板6的两个第二通孔61设置，使得离合滑块351可沿轴线L1往复移动。第二凸块3511上设有斜面35111，斜面35311可与第一凸块333相抵接，当推杆33的受力面332受外力作用沿W方向移动时，推杆33上的第一凸块333挤压斜面35111，使得离合滑块351在轴线L1方向上向靠近轮毂4一侧移动，同时挤压离合传动件352，离合传动352沿着轴线L1向轮毂4方向移动，使得离合传动件352的第二凸部3522与轮毂4的第一凸部42啮合，此时旋转力接收件31旋转时可将旋转力通过离合件35传递至轮毂4，进而传递给感光鼓。当作用在受力面332上的外力消失时，推杆33在第一螺旋弹簧34的弹力作用下沿与W相反方向移动，推杆33上的第一凸块333不再挤压离合滑块351的斜面35111，使得离合滑块351也将不再挤压离合传动件352，在第二螺旋弹簧353的弹力作用下，离合传动件352的第二凸部3522与轮毂4上的第一凸部42处于分离状态，此时旋转力接收件31转动时，轮毂4不旋转。
下面结合参考图4、图7、图9、图10，介绍处理盒100的装机过程。图7是未关闭成像设备300的门盖302时的成像设备300和处理盒100的结构示意图；图9是未关闭成像设备300的门盖302时，处理盒100的推杆33未受外力推压状态处理盒100的局部结构示意图；图10是实施例1门盖302关闭，处理盒100在推杆33的受力面332受到门盖302推压作用力时的局部状态示意 图。成像设备300的门盖302上有一压迫块3021。当处理盒100安装至成像设备300的腔室中，处理盒100的凸爪3111与成像设备300侧的输出突起3011相联接，关闭门盖302，门盖302上的压迫块3021抵压在推杆33的受力面332，推杆33在推压力的作用下，沿方向W移动。在推杆33沿方向W移动过程中，推杆33上的施力部331与筒状件322上的受力部3222相互啮合并带动筒状件322沿与a方向旋转，此时旋转力接收件31不发生转动。
结合参考图3至图5，图11、图12，推杆33的移动使得推杆33上的第一凸块333挤压离合滑块351上的第二凸块3511的斜面35111，使得离合滑块351沿着轴线L1向靠近轮毂4的方向移动，同时挤压离合传动件352，使得离合传动件352向靠近轮毂4的方向移动，进而离合传动件352上的第二凸部3522与轮毂4上的第一凸部42啮合。当成像设备启动工作时，成像设备的旋转力输出头301转动将会带动旋转力接收件31转动，进而实现凸爪3111与旋转力输出头301的相互联接。结合参考图3和图4，在处理盒工作状态下，旋转力接收件31从成像设备中的旋转力输出头301接收旋转力沿a的反方向旋转。在旋转力接收件31旋转过程中，第二接触面3212与第二端面32212滑动接触的同时，第二接触面3212抵压第二端面32212使悬臂发生弹性变形，进而使的第二接触面3212滑过第二端面32212，从而使旋转力接收件31继续旋转，而使筒状件322不旋转。
下面结合参考图4至图15c介绍处理盒100的拆卸过程。
参考图13b，本实施例中，旋转力接收件31的预设位置被预设为：当旋转力接收件31处于预设位置时，旋转力接收部311的两个凸爪3111的连线基本垂直于处理盒100拆卸方向p。
本实施例中，在打开门盖302时，门盖302不再挤压推杆33上的受力面332，推杆33在第一螺旋弹簧34的弹性力作用下，沿与W相反方向移动。在推杆33沿与W相反方向移动过程中，推杆33上的第一凸块333与离合滑块351上的第二凸块3511的斜面35111分离，离合滑动件351不再挤压离合传动件352，离合传动件352在第二螺旋弹簧353的弹力作用下，使得离合传动件352的第二凸部3522与轮毂4上的第一凸部42分离。随着推杆 33的继续沿与W相反移动，推杆33上的施力部331与筒状件322受力部3222啮合，推杆33继续沿与W相反方向移动将带动筒状件322沿a的反方向转动，而筒状件322上的悬臂3221推动旋转力接收件31上的从动部321一起转动，可使得旋转力接收件31一起沿a的反方向向预设位置旋转。
由于成像设备停止工作时，旋转力输出头301和旋转力接收件31的停止旋转后的位置是随机的，但经过位置调整机构的调整后，二者之间的位置基本可以分为三种情况。
假设箭头P所示的方向为处理盒的取出方向，旋转力输出头301上对称设置的两个输出突起3011的端部在处理盒取出方向p上的最大投影距离为H1；旋转力接收件31处于预设位置时，旋转力接收件31上对称设置的两个凸爪3111间距离最近的两点在处理盒取出方向P上的投影距离为H。
图13a是成像设备停止工作时旋转力输出头的输出突起3011与旋转力接收件31上对称设置的两凸爪3111间的一任意位置关系示意图，此种情况如果直接取出处理盒，二者在取出方向上会有干涉，会造成输出突起3011和凸爪3111的磨损。图13b是经过位置调整机构调整后输出突起3011与凸爪3111间的位置关系示意图，如图13b所示，旋转力输出头301不可转动，但在门盖302打开时，在位置调整装置的作用下旋转力接收件31沿a反方向转动到预设位置，此时H1＜H，在处理盒取出方向P上，凸爪3111与输出突起3011不会发生干涉。参考图13c，处理盒可顺利地从成像设备中取出。
图14a是成像设备停止工作时旋转力输出头的输出突起3011与旋转力接收件31上对称设置的两凸爪3111间的另一任意位置关系示意图。此种情况如果直接取出处理盒，二者在取出方向上会有干涉，会造成输出突起3011和凸爪3111的磨损。图14b是经过位置调整机构调整后输出突起3011与凸爪3111间的位置关系示意图。如图14b所示，在位置调整装置的作用下旋转力接收件31沿a反方向转动到预设位置，但此时虽然存在H1＞H，但凸爪3111与输出突起3011之间会存在一定的干涉，但是，由于在容纳处理盒的成像设备的腔室内在大致垂直于处理盒取出方向p 的方向q上存在自由活动空间，使得处理盒可在q方向上移动，参考图14c，此时只要稍微活动一下处理盒，处理盒便可顺利地从成像设备中取出。
图15a是成像设备停止工作后旋转力输出头301的输出突起3011处于旋转力接收件31的预设位置时旋转力输出头的输出突起3011与旋转力接收件31上对称设置的两凸爪3111间的位置关系示意图。此种情况如果直接取出处理盒，二者在取出方向上会有干涉，会造成输出突起3011和凸爪3111的磨损。图15b是经过位置调整机构调整后输出突起3011与凸爪3111间的位置关系示意图。如图15b所示，在位置调整装置的作用下旋转力接收件31上的凸爪3111沿a反方向转动直至受到输出突起3011的阻碍，此时旋转力接收件不能转动到预设位置，而是处于最接近预设位置的位置。虽然此时仍存在H1＞H，在取出显影盒时凸爪3111与输出突起3011之间会存在一定的干涉，但由于在容纳处理盒的成像设备的腔室内在大致垂直于处理盒取出方向p的方向q上存在自由活动空间，使得处理盒可在q方向上移动，参考图15c，此时只要稍微活动一下处理盒，处理盒便可顺利地从成像设备中取出。
实施例2
实施例2处理盒与实施例1处理盒100的结构基本相同，区别仅在于施力部和筒状件的受力部的结构不同。
如图16所示，在筒状件322＇的圆周外壁上设有受力部3222＇，受力部3222＇在本实施例中为多个凸轮且其在筒状件322＇的外壁沿圆周方向一圈布满设置。施力部331＇为与受力部3222＇相啮合的凹槽。
最后需要强调的是，以上所述仅为本发明的优选实施例，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种变化和更改，旋转体可以是显影辊、送粉辊或充电辊，驱动力接收组件可以安装在任何旋转体的一端，驱动力接收组件亦可以不包含轮毂、离合件等等，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
