Description

动力接收部件以及处理盒Power receiving part and processing box
本申请要求于2018年06月21日提交中国专利局、申请号为201820956460.5、发明名称为“动力接收部件的处理盒”的中国专利申请的优先权，其全部内容通过交叉引用结合在本申请中。This application claims priority from a Chinese patent application filed on June 21, 2018 with the Chinese Patent Office, application number 201820956460.5, and invention name "Processing Box for Power Receiving Component", the entire contents of which are incorporated in this application by cross-reference. .
技术领域Technical field
本申请属于电子成像领域，涉及一种动力接收部件，尤其是包含该动力接收部件的处理盒。The present application belongs to the field of electronic imaging, and relates to a power receiving component, particularly a processing box containing the power receiving component.
背景技术Background technique
处理盒作为可更换耗材广泛的使用在打印机、复印机等电子成像装置中。在成像过程中电子成像装置主要工作过程如下：充电组件给感光部件表面充上均匀预定电荷；带有预定电荷的感光部件表面接受曝光处理后形成静电潜像；显影组件将显影剂送上感光部件，使感光部件表面的静电潜像获得显影；经转印作用后，静电潜像上的显影剂被转移到图像记录介质如纸张上；清洁组件清洁感光部件表面上的未完全转印的显影剂，以让感光部件进入下一次充电，即下一个循环过程。Process cartridges are widely used as replaceable consumables in electronic imaging devices such as printers and copiers. The main working process of the electronic imaging device during the imaging process is as follows: the charging component charges the surface of the photosensitive member with a uniform predetermined charge; the surface of the photosensitive member with the predetermined charge is subjected to exposure processing to form an electrostatic latent image; the developing component sends the developer to the photosensitive member To develop the electrostatic latent image on the surface of the photosensitive member; after the transfer, the developer on the electrostatic latent image is transferred to the image recording medium such as paper; the cleaning component cleans the incompletely transferred developer on the surface of the photosensitive member To allow the photosensitive member to enter the next charge, that is, the next cycle.
在这个循环过程中，处理盒部分至少包括为感光部件，感光部件充电的充电部件，为感光部件提供显影剂的显影部件。现有技术中，所述的感光部件为感光鼓，所述的显影部件为显影辊。处理盒本身不包含如马达的驱动力生成部件，而是通过从其所位于的电子成像装置上接收旋转驱动力。由于处理盒是运用在电子成像装置上的可更换耗材，为保证普通用户可以轻松的自主更换处理盒，因而接收旋转驱动力时处理盒上设有的动力接收部件和电子成像装置上设有的旋转驱动力传递部件可以在传递旋转驱动力时耦合，不传递旋转驱动力时可以分离。During this cycle, the process cartridge portion includes at least a photosensitive member, a charging member that charges the photosensitive member, and a developing member that provides a developer for the photosensitive member. In the prior art, the photosensitive member is a photosensitive drum, and the developing member is a developing roller. The process cartridge itself does not include a driving force generating part such as a motor, but receives a rotational driving force from an electronic imaging device where it is located. Since the processing box is a replaceable consumable used on the electronic imaging device, in order to ensure that ordinary users can easily replace the processing box on their own, the power receiving part provided on the processing box and the electronic imaging device are provided when receiving the rotational driving force. The rotation driving force transmission member may be coupled when the rotation driving force is transmitted, and may be separated when the rotation driving force is not transmitted.
通常在处理盒中，用于产生显影剂静电潜像的感光部件感光鼓、用于向感光部件提供显影剂的显影元件显影辊、用于搅拌显影剂的搅拌架、向显影元件提供显影剂的搅拌架，以及部分型号的处理盒中用于向感光部件充电的充电部件充电辊均为可旋转的类似于辊状结构，因此统称为旋转辊。动力接 收部件可以设置在任一旋转辊上并通过齿轮组向其他旋转辊传递旋转驱动力，或直接驱动齿轮组带动各旋转辊。Usually in a process cartridge, a photosensitive member photosensitive drum for generating a latent electrostatic image of a developer, a developing element developing roller for supplying the developer to the photosensitive member, a stirring frame for stirring the developer, and a developer supplying the developer to the developing element. The stirring frame and the charging member charging roller used to charge the photosensitive member in some types of process boxes are rotatable similar to a roller-like structure, so they are collectively referred to as rotating rollers. The power receiving part can be arranged on any rotating roller and transmit the rotational driving force to other rotating rollers through the gear set, or directly drive the gear set to drive each rotating roller.
在现有技术中，显影剂以及显影辊等部分设置在粉仓中，感光鼓以及收集的打印废粉设置在废粉仓中。当然对于废粉仓而言，也有部分处理盒不设置收集废粉的部分。通常粉仓和废粉仓是连接成一体安装进电子成像装置的，但是也有部分型号的设计为分体式，即把粉仓和废粉仓分开安装进电子成像装置中。在本申请中仅以一体结构为例。In the prior art, parts such as a developer and a developing roller are provided in a powder container, and a photosensitive drum and collected printing waste toner are provided in the waste powder container. Of course, for the waste toner box, some processing boxes are not provided with a part for collecting waste toner. Usually, the powder container and the waste powder container are integrated into the electronic imaging device, but some models are designed as a separate type, that is, the powder container and the waste toner container are separately installed in the electronic imaging device. In this application, only an integrated structure is taken as an example.
对于彩色处理盒而言，因为对于部分颜色成像时不需要所有颜色的处理盒参与，为了防止显影部件和感光部件长时间互相接触产生挤压造成损伤影响成像，或是显影部件和感光部件相互摩擦产生损伤，因此当该颜色的处理盒不工作时，现有技术中采取了一种辊鼓分离的方法，如图2，即让包含显影组件和显影剂的粉仓与包含感光部件和收集到的废弃显影剂的废粉仓之间发生相对运动，从而使显影组件相对于感光组件不再接触。在本申请中仅以粉仓带动显影部件运动为例.当然，也可以设置为废粉仓带动感光部件相对于显影部件运动，由于原理相同不再赘述。For color process cartridges, because the process cartridges of all colors are not required to participate in the imaging of some colors, in order to prevent the development member and the photosensitive member from contacting each other for a long time to cause damage and affect the imaging, or the developing member and the photosensitive member rub against each other. Damage occurs, so when the color process cartridge is not working, a roller separation method is adopted in the prior art, as shown in FIG. 2, that is, the powder container containing the developing component and the developer is separated from the powder containing the photosensitive member and collected. Relative movement occurs between the waste toner bins of the waste developer, so that the developing component is no longer in contact with the photosensitive component. In this application, only the powder container drives the developing component as an example. Of course, it can also be set to use a waste toner container to drive the photosensitive component relative to the developing component. Since the principle is the same, it will not be described again.
当粉仓和显影元件运动时，如果在粉仓上设置一个固定的动力接收部件，当该动力接收部件和电子成像装置连接较松时，虽然容易脱离啮合，但是却很难在粉仓运动回来继续工作时再次啮合；当该动力接收部件和电子成像装置连接较紧时，却容易造成因为无法脱离啮合而阻止辊鼓分离动作。因此有必要设置一个动力接收部件保持在整个辊鼓分离过程中始终与电子成像装置啮合。而如果简单的使用十字联轴或者其他类似结构也很难保证第一次装处理盒的时候能够啮合，从而导致动力接收部件和电子成像装置始终不能啮合。When the powder container and the developing element are moving, if a fixed power receiving component is provided on the powder container, when the power receiving component and the electronic imaging device are loosely connected, although it is easy to disengage, it is difficult to move back in the powder container. Engage again when you continue to work; when the power receiving part is tightly connected to the electronic imaging device, it is easy to prevent the drum from separating because it cannot be disengaged. Therefore, it is necessary to set a power receiving part to keep the meshing with the electronic imaging device during the whole drum separation process. However, if a simple cross coupling or other similar structure is used, it is difficult to ensure that it can be engaged when the process cartridge is first installed, which results in that the power receiving component and the electronic imaging device cannot always be engaged.

Obviously, the described embodiments are the present application. Some embodiments, but not all embodiments.

The following examples are used to illustrate the application, but are not intended to limit the scope of the application.
在电子成像装置中，驱动显影辊的驱动部件是位于固定位置的，而进行辊鼓分离的处理盒的动力接收部件在辊鼓分离过程中是相对于该驱动部件运动的。因此必须要使用可以活动的动力接收部件。本申请主要解决的问题在于如何保证该可以活动的动力接收部件在处理盒装入电子成像装置后直接与驱动部件啮合；辊鼓分离过程中该可以活动的动力接收部件始终与驱动部件保持啮合；取出处理盒时动力接收部件能够恢复并保持在与装入时相同的位置，从而保证下一次装入处理盒时能够顺利啮合。In the electronic imaging device, the driving member that drives the developing roller is located at a fixed position, and the power receiving member of the process cartridge that performs drum separation is moved relative to the driving member during the drum separation. Therefore, it is necessary to use a movable power receiving component. The main problem solved by this application is how to ensure that the movable power receiving part is directly engaged with the driving part after the processing box is installed in the electronic imaging device; the movable power receiving part is always engaged with the driving part during the drum separation process; When the process box is removed, the power receiving part can be restored and maintained in the same position as when it is loaded, thereby ensuring that the next time the process box is loaded, the meshing can be smoothly engaged.

图3中为本实施例中涉及的处理盒，包含本实施例中涉及的动力接收部件。如图处理盒上包含第一框架11和第二框架12，第二框架上还包含感光部件17。FIG. 3 is a process box involved in this embodiment, and includes a power receiving part involved in this embodiment. As shown in the figure, the process box includes a first frame 11 and a second frame 12, and the second frame further includes a photosensitive member 17.
图4具体的体现了第一框架11的结构，图5为图4中第一框架11位于处理盒长度方向两端的侧壁中设置有动力接收部件的一端。如图5所示，第一框架11位于处理盒长度方向两端的侧壁中设置有动力接收部件的一端上设置有端盖13，限位部分14通过弹性件141连接在端盖13上。端盖13覆盖并约束其他零件，防止其他零件从处理盒上脱出。优选地，弹性件141为弹簧。限位部分14可以在弹性件141的作用下，相对于端盖13沿处理盒长度方向伸缩。端盖13上还设置有一个开口131，驱动头15与开口131在垂直于处理盒长度方向的面上的投影至少有一部分是重合的。优选地，驱动头15在处理盒长度方向上的投影比端盖13在处理盒长度方向上的投影更远离位于处理盒长度方向两端的侧壁中另一端(即不设置动力接收部件的一端)在处理盒长度方向上的投影。FIG. 4 specifically illustrates the structure of the first frame 11, and FIG. 5 is an end of the first frame 11 in FIG. 4, which is provided with a power receiving member in sidewalls of the processing box at both ends in the longitudinal direction. As shown in FIG. 5, an end cover 13 is provided on one end of the side wall of the first frame 11 disposed at both ends in the lengthwise direction of the processing box, and the end cover 13 is connected to the end cover 13 through an elastic member 141. The end cover 13 covers and restrains other parts to prevent other parts from coming out of the process box. Preferably, the elastic member 141 is a spring. The limiting portion 14 can expand and contract along the length of the processing box relative to the end cover 13 under the action of the elastic member 141. The end cover 13 is further provided with an opening 131, and at least a part of the projection of the driving head 15 and the opening 131 on a surface perpendicular to the length direction of the process box is coincident. Preferably, the projection of the driving head 15 in the length direction of the processing box is farther from the other end of the side walls at both ends of the length of the processing box than the projection of the end cover 13 in the length of the processing box (that is, the end where no power receiving member is provided). Projection in the length direction of the process box.
图6和图7展示了处理盒向电子成像装置内部安装的过程。此时电子成像装置的门盖96处于打开位置，处理盒可以安装进电子成像装置的主体97中。限位部分14在处理盒向主体97安装过程中位于安装方向的前方。当处理盒没有安装进电子成像装置或没有安装到位时，限位部分14不与处理盒外部的其他部分抵接，弹性件141推动限位部分处于相对伸出的状态，如图5所示；当处理盒在电子成像装置安装到位时，限位部分14与电子成像装置的内壁抵接并被电子成像装置的内壁推动向处理盒内部运动，进入相对缩进的状态，如图8所示。6 and 7 illustrate a process in which the process cartridge is installed inside the electronic imaging device. At this time, the door 96 of the electronic imaging device is in the open position, and the process cartridge can be installed in the main body 97 of the electronic imaging device. The limiting portion 14 is located forward of the mounting direction during the process in which the process cartridge is mounted on the main body 97. When the processing box is not installed in the electronic imaging device or is not in place, the limiting portion 14 does not abut against other parts outside the processing box, and the elastic member 141 pushes the limiting portion in a relatively extended state, as shown in FIG. 5; When the processing box is installed in place in the electronic imaging device, the limiting portion 14 abuts the inner wall of the electronic imaging device and is pushed toward the inside of the processing box by the inner wall of the electronic imaging device and enters a relatively retracted state, as shown in FIG.
图9在图5的基础上移除了端盖13，从而可以更清晰的看到端盖13内部的结构。当然，限位部分14在正常情况下应该仅通过弹性件141连接在端盖13上，但是此处为了展示限位部分14与其他部分的相互作用，仍然示出了限位部分14和弹性件141。驱动头15与第一固定部143和第二固定部144相连接，第一固定部143和第二固定部144之间存在夹角，优选地，第一固定部143和第二固定部144垂直。第一固定部143和第二固定部144两者中可以随意替换更靠近处理盒内部和更靠近处理盒外部，即第一固定部143可以相对于第二固定部144更靠近处理盒内部，也可以使用类似的设计，使第二固定部144比第一固定部143更靠近处理盒内部。为了区别，称垂直于处理盒安装方向的为第一固定部143。限位部分14靠近第一固定部143和第二固定部144的一端设置有限位柱142，优选地，所述限位柱142为两个，一个可与第一固定部143抵接，另一个可与第二固定部144抵接。当限位柱142与第一固定部143和第二固定部144抵接时，框架11、限位柱142将第一固定部143和第二固定部144的位置限定，使第一固定部143和第二固定部144不能沿垂直于处理盒长度方向的面进行运动。此时驱动头15由于与第一固定部143和第二固定部144连接，因此驱动头15也不能在十字联轴16的约束下沿所述垂直于处理盒长度方向的平面进行平动。FIG. 9 removes the end cover 13 from FIG. 5, so that the structure inside the end cover 13 can be seen more clearly. Of course, the limiting portion 14 should be connected to the end cap 13 only through the elastic member 141 under normal circumstances. However, in order to show the interaction between the limiting portion 14 and other parts, the limiting portion 14 and the elastic member are still shown here. 141. The driving head 15 is connected to the first fixing portion 143 and the second fixing portion 144. An angle exists between the first fixing portion 143 and the second fixing portion 144. Preferably, the first fixing portion 143 and the second fixing portion 144 are perpendicular to each other. . Both the first fixing portion 143 and the second fixing portion 144 may be replaced closer to the inside of the process box and closer to the outside of the process box, that is, the first fixing portion 143 may be closer to the inside of the process box than the second fixing portion 144. A similar design may be used to make the second fixing portion 144 closer to the inside of the process box than the first fixing portion 143. For the purpose of distinction, the first fixing portion 143 is referred to as being perpendicular to the mounting direction of the process cartridge. One end of the limiting portion 14 near the first fixing portion 143 and the second fixing portion 144 is provided with a limiting pole 142. Preferably, there are two limiting poles 142, one of which can abut the first fixing portion 143 and the other It can be in contact with the second fixing portion 144. When the limiting post 142 is in contact with the first fixing part 143 and the second fixing part 144, the frame 11 and the limiting post 142 limit the positions of the first fixing part 143 and the second fixing part 144 so that the first fixing part 143 The second fixing portion 144 cannot move along a surface perpendicular to the longitudinal direction of the process cartridge. At this time, since the driving head 15 is connected to the first fixing portion 143 and the second fixing portion 144, the driving head 15 cannot be translated along the plane perpendicular to the length direction of the process box under the constraint of the cross coupling 16.
图10在图6的基础上移除了限位部分14、弹性件141、第一固定部143和第二固定部144，以更好的展示驱动头15、十字联轴16和显影部件18之间的位置关系。十字联轴16的一端与显影部件18连接，另一端与驱动头15连接，使得驱动头15从电子成像装置中接收旋转驱动力后能传递给显影部件18，同时又存在一定量的旷量，使驱动头15能在十字联轴支撑的范围内沿垂直于处理盒长度方向的平面进行平动，从而帮助驱动头与电子成像装置更好的啮合，使辊鼓分离过程中不会脱离啮合。FIG. 10 removes the limiting portion 14, the elastic member 141, the first fixing portion 143, and the second fixing portion 144 on the basis of FIG. 6 to better show the driving head 15, the cross coupling 16 and the developing member 18. Location relationship. One end of the cross coupling 16 is connected to the developing member 18 and the other end is connected to the driving head 15 so that the driving head 15 can transmit the driving force to the developing member 18 after receiving the rotational driving force from the electronic imaging device, and at the same time there is a certain amount of space. The driving head 15 can be translated in a plane perpendicular to the length direction of the process box within the range supported by the cross coupling, thereby helping the driving head to better engage with the electronic imaging device, so that the rollers will not be disengaged during the separation of the drums.
图3至图5中所展示的动力接收部件的状态均为处理盒尚未安装到电子成像装置上时的状态。此时限位柱142与第一固定部143和第二固定部144抵接，框架11、限位柱142将第一固定部143和第二固定部144的位置限定，使第一固定部143和第二固定部144不能沿垂直于处理盒长度方向的面进行运动。驱动头15由于与第一固定部143和第二固定部144连接，因此驱动头15也不能在十字联轴16的约束下沿所述垂直于处理盒长度方向的平面进行 平动，如图11所示，此时状态与图5中状态相对应。此时图11的上下方向为处理盒长度方向。在图11中，十字联轴16直接与显影部件18连接传递动力。The states of the power receiving parts shown in FIGS. 3 to 5 are states when the process cartridge has not been mounted on the electronic imaging device. At this time, the limiting post 142 is in contact with the first fixing part 143 and the second fixing part 144, and the frame 11 and the limiting post 142 limit the positions of the first fixing part 143 and the second fixing part 144 so that the first fixing part 143 and the The second fixing portion 144 cannot move along a surface perpendicular to the longitudinal direction of the process cartridge. Because the driving head 15 is connected to the first fixing portion 143 and the second fixing portion 144, the driving head 15 cannot be translated along the plane perpendicular to the length direction of the process box under the constraint of the cross coupling 16, as shown in FIG. 11 As shown, the state at this time corresponds to the state in FIG. 5. At this time, the vertical direction of FIG. 11 is the length direction of the process cartridge. In FIG. 11, the cross coupling 16 is directly connected to the developing member 18 to transmit power.
当所述处理盒安装到所述电子成像装置上时，驱动头15所在的位置刚好可以与电子成像装置上的旋转驱动力传递部件啮合，且此时由于与电子成像装置内壁抵接，限位部分14沿处理盒长度方向向靠近处理盒长度方向两端的侧壁中另一端(即不设置动力接收部件的一端)运动，限位柱142不再抵接第一固定部143和第二固定部144，如图12所示。此时状态与图8中状态相对应。When the process cartridge is mounted on the electronic imaging device, the position of the driving head 15 can just be engaged with the rotational driving force transmission member on the electronic imaging device, and at this time, due to the abutment with the inner wall of the electronic imaging device, the position is limited The portion 14 moves along the length direction of the processing box toward the other end of the side wall near the two ends of the processing box length (that is, the end where no power receiving member is provided), and the limiting post 142 no longer abuts the first fixing portion 143 and the second fixing portion 144, as shown in Figure 12. The state at this time corresponds to the state in FIG. 8.
由于限位柱142不再进行抵接限位，因此驱动头15可以在十字联轴16的支撑下在垂直于处理盒长度方向的平面上进行平动。由于电子成像装置上的旋转驱动力传递部件固定在电子成像装置的内壁上，倘若使用固定的动力接收部件进行图2中描述的感光部件17与显影部件18之间的接触和分离的动作会改变动力接收部件相对于电子成像装置的位置从而造成脱离啮合，而使用本实施例中的动力接收部件可以进行图2中描述的感光部件17与显影部件18之间的接触和分离的动作使驱动头15和电子成像装置上的旋转驱动力传递部件不脱离啮合，从而使处理盒在电子成像装置中正常工作。同理，其他类似的导致处理盒相对电子成像装置发生位移的运动，只要在十字联轴16支撑驱动头15的旷量之内，都可以使本实施例中的处理盒正常工作。Since the limit post 142 no longer abuts the limit position, the driving head 15 can perform translation on a plane perpendicular to the length direction of the process box under the support of the cross coupling 16. Since the rotational driving force transmission member on the electronic imaging device is fixed on the inner wall of the electronic imaging device, if a fixed power receiving member is used to perform the contact and separation actions between the photosensitive member 17 and the developing member 18 described in FIG. 2 The position of the power receiving member relative to the electronic imaging device causes disengagement, and the power receiving member in this embodiment can perform contact and separation between the photosensitive member 17 and the developing member 18 described in FIG. 2 to make the driving head 15 and the rotational driving force transmitting member on the electronic imaging device are not disengaged, so that the process cartridge works normally in the electronic imaging device. Similarly, other similar movements that cause the process cartridge to be displaced relative to the electronic imaging device can make the process cartridge in this embodiment work normally as long as the crosshead 16 supports the driving head 15.
图13和图14是从端盖13一侧观察处理盒时限位部分14与第一固定部143和第二固定部144以及驱动头15之间的位置关系图。如图13所示，此时处理盒安装完成并且处于正常打印过程中，此时状态与图8、图12中状态相对应。之后当该颜色的处理盒不进行打印时，辊鼓分离，此时驱动头15和电子成像装置的驱动部件保持啮合并且不进行位移，处理盒的粉仓相对于处理盒的废粉仓发生运动，状态如图14所示。当辊鼓分离结束时，又从图14中的状态恢复到图13中的状态。13 and 14 are positional relationship diagrams between the stop portion 14 and the first and second fixing portions 143 and 144 and the driving head 15 when the process cartridge is viewed from the side of the end cover 13. As shown in FIG. 13, at this time, the process cartridge is installed and is in the normal printing process, and the state at this time corresponds to the state in FIGS. 8 and 12. After that, when the process box of the color is not printed, the drum is separated. At this time, the driving head 15 and the driving part of the electronic imaging device remain engaged and do not move, and the powder box of the process box moves relative to the waste toner box of the process box. The state is shown in Figure 14. When the drum separation ends, the state shown in FIG. 14 is restored to the state shown in FIG. 13.
当处理盒从电子成像装置中取下时，由于此时电子成像装置已经停止进行电子成像回到了处理盒装入电子成像装置时的位置，取出过程中弹性件141带动限位部分14沿处理盒长度方向向远离处理盒长度方向两端的侧壁中另一端(即不设置动力接收部件的一端)运动，限位柱142重新与第一固定部 143和第二固定部144抵接，框架11、限位柱142将第一固定部143和第二固定部144的位置限定，驱动头15此时也不能沿垂直于处理盒长度方向的平面进行平动。因此取出的处理盒又恢复到了图5、图11中的状态。When the processing box is removed from the electronic imaging device, since the electronic imaging device has stopped performing electronic imaging at this time and returned to the position when the processing box was loaded into the electronic imaging device, the elastic member 141 drives the limiting portion 14 along the processing box during removal. The length direction moves toward the other end (that is, the end where no power receiving member is provided) of the side wall far from the two ends of the processing box in the length direction, and the limiting post 142 abuts the first fixing portion 143 and the second fixing portion 144 again. The limiting post 142 restricts the positions of the first fixing portion 143 and the second fixing portion 144, and the driving head 15 cannot perform translation along a plane perpendicular to the length direction of the process box at this time. Therefore, the removed process cartridge is restored to the state shown in FIG. 5 and FIG. 11.
实施例二Example two
本实施例中方案在实施例一的基础上，对于实际的生产和使用过程中出现的一些问题进行了改进。因此对于所有未明确说明的内容，本实施例中内容依照实施例一中设置。On the basis of the first embodiment, the solution in this embodiment improves some problems that occur during actual production and use. Therefore, for all content that is not explicitly described, the content in this embodiment is set according to the first embodiment.
如图15和图16所示，为了防止运输过程中限位部分14被碰撞而向处理盒内部方向运动，或用户拿到处理盒后因好奇而按压限位部分14，造成限位柱142没能抵接第一固定部143和第二固定部144，驱动头15在安装进电子成像装置时并没有位于图5、图11中的状态从而驱动头15无法在安装时和电子成像装置的驱动部件啮合，因此设置了一个端盖护罩19。端盖护罩19包含与处理盒固定的固定部分192和用于用户拆除端盖护罩19的把手191。优选地，在端盖护罩19上粘贴说明内容，提示用户拆除端盖护罩19并且不要按压限位部分14。As shown in FIG. 15 and FIG. 16, in order to prevent the limit portion 14 from being collided during transportation and moving toward the inside of the processing box, or the user presses the limit portion 14 because of curiosity after receiving the processing box, causing the limit column 142 to fail. It can abut the first fixing portion 143 and the second fixing portion 144. When the driving head 15 is installed in the electronic imaging device, it is not in the state shown in FIG. 5 and FIG. 11 so that the driving head 15 cannot be driven by the electronic imaging device during installation. The parts engage, so an end cap shield 19 is provided. The end cap shield 19 includes a fixing portion 192 fixed to the process cartridge and a handle 191 for a user to remove the end cap shield 19. Preferably, the description content is pasted on the end cover shield 19 to prompt the user to remove the end cover shield 19 and do not press the limiting portion 14.
如图17所示为改进后的端盖13。改进后的端盖由两部分构成，分别是第一端盖131和第二端盖132。在工厂生产的装配过程中实施例一中的一体式端盖会导致需要放置好端盖下方的十字联轴16、驱动头15、第一固定部143、第二固定部144以及限位部分14之后再进行安装，倘若安装端盖的过程中对一个或数个零件发生了干涉，导致其位置发生了变化，则无法继续安装端盖13，需要将端盖13卸下并重新调整位置，之后再进行安装。这样不仅增加了生产难度，还降低了效率。因此使用本实施例中的改进后的端盖进行代替。在布置好端盖下方的零件之后，先安装第二端盖132。优选地，使用在短螺钉孔135中打螺钉的方式将第二端盖固定在处理盒上。优选地，此时不将在短螺钉孔135中的螺钉完全安装到位，而是处于一种端盖下方的零件也不会脱出，第二端盖132也不会脱落的状态，之后通过第二端盖132上的窗口136调整零件位置(即用于调整驱动头15、十字联轴16和限位部分14的位置，以及能够调整第一固定部143和第二固定部144分别与上述零件的相对位置)，使各个零件处于合适的位置，再将短螺钉孔135中的螺钉完 全安装到位。之后安装第一端盖131，优选地经由第一长螺钉孔133、第二长螺钉孔134打螺钉，将第一端盖和第二端盖固定在处理盒上。Figure 17 shows the improved end cap 13. The improved end cap is composed of two parts, a first end cap 131 and a second end cap 132, respectively. During the assembly process in the factory, the integrated end cap in the first embodiment will result in the cross coupling 16, the driving head 15, the first fixing portion 143, the second fixing portion 144, and the limiting portion 14 under the end cover. Then install it later. If one or several parts interfere during the process of installing the end cap, causing the position to change, you cannot continue to install the end cap 13. You need to remove the end cap 13 and readjust the position. Install it again. This not only increases production difficulty, but also reduces efficiency. Therefore, the improved end cap in this embodiment is used instead. After the parts under the end cap are arranged, the second end cap 132 is first installed. Preferably, the second end cover is fixed on the process box by screwing in the short screw hole 135. Preferably, at this time, the screws in the short screw holes 135 are not completely installed in place, but the parts under the end cap will not come off, and the second end cap 132 will not fall off. The window 136 on the end cover 132 adjusts the position of the parts (that is, used to adjust the positions of the driving head 15, the cross coupling 16 and the limiting portion 14), and can adjust the first fixing portion 143 and the second fixing portion 144 and the above-mentioned parts, respectively. Relative position), so that each part is in a proper position, and then fully install the screws in the short screw holes 135 in place. After that, the first end cover 131 is installed, and preferably, the first end cover and the second end cover are fixed on the process box by screwing through the first long screw hole 133 and the second long screw hole 134.
为了简便起见，将以上实施方式中处理盒未装入电子成像装置中时动力接收部件的位置和与该位置相同的状态称为第一位置；处理盒在电子成像装置内正常进行工作时的动力接收部件的位置和与该位置相同的状态称为第二位置；处理盒进行辊鼓分离动作时动力接收部件的位置称为第三位置。For the sake of simplicity, the position of the power receiving member when the process cartridge is not installed in the electronic imaging device and the same state as the first position are referred to as the first position; the power when the process cartridge normally works in the electronic imaging device The position of the receiving member and the same state as the position are referred to as a second position; the position of the power receiving member when the process cartridge performs the roller separation operation is referred to as a third position.
