技术领域technical field

本实用新型涉及一种在如激光打印机、复印机或传真机等成像设备中使用的处理盒。The utility model relates to a processing cartridge used in imaging equipment such as laser printers, copiers or fax machines.

背景技术Background technique

成像设备利用电子照相成像处理在记录材料上形成图像。成像设备的示例包括电子照相复印机、电子照相打印机（例如激光束打印机、LED打印机）、传真机、文字处理机等。处理盒包括作为图像承载构件的电子照相感光鼓和能够作用在鼓上的处理装置（显影剂承载构件（显影辊））中的至少一种。所述电子照相感光鼓和所述处理装置一体化构造为可拆卸安装至成像设备中的盒。盒可以包括一体的鼓和显影辊，或者可以包括鼓，或者可以包括显影辊。包括感光鼓的盒是鼓单元，包括显影辊的盒是显影单元。The image forming apparatus forms an image on a recording material using an electrophotographic image forming process. Examples of image forming apparatuses include electrophotographic copiers, electrophotographic printers (eg, laser beam printers, LED printers), facsimile machines, word processors, and the like. The process cartridge includes at least one of an electrophotographic photosensitive drum as an image bearing member and a processing device (developer bearing member (developing roller)) capable of acting on the drum. The electrophotographic photosensitive drum and the processing device are integrally constructed as a cartridge detachably mounted in an image forming apparatus. The cartridge may include an integral drum and developing roller, or may include a drum, or may include a developing roller. The cartridge including the photosensitive drum is the drum unit, and the cartridge including the developing roller is the developing unit.

如图1a和图1b所示，现有技术公开了一种鼓单元101与显影单元100的分离结构，其中，处理盒沿L方向安装至成像设备中，成像设备中的施力构件105沿M和N方向移动，施力构件105由弹簧106支撑在预定位置。当处理盒沿L方向安装至成像设备中时，设置在显影单元100上的力接收构件103下压上述施力构件105至压缩位置，施力构件105在压缩位置处沿N方向移动；当施力构件105上的突起部107越过上述力接收构件103后，施力构件105被弹簧106弹起并与力接收构件103上的凹部108啮合，施力构件105再沿M方向移动而通过力接收构件103推动显影单元100旋转，使得显影单元100中的显影辊102与鼓单元101中的感光鼓104分离。上述技术方案，由于采用了施力构件上的突起部与显影单元中力接收构件的凹部啮合的机构，使得施力构件在推动显影单元旋转时容易出现卡死的情况。由于需要压迫成像设备中的施力构件105缩进，使得支撑施力构件105的弹簧106一直处于压缩状态，容易造成弹簧106回弹不灵活的问题，进而导致施力构件105不能正常与力接收构件103啮合的问题。As shown in FIG. 1a and FIG. 1b, the prior art discloses a separation structure of thedrum unit 101 and the developingunit 100, wherein the process cartridge is installed in the image forming apparatus along the L direction, and theforce applying member 105 in the image forming apparatus is along the M direction. And moving in the N direction, theurging member 105 is supported at a predetermined position by thespring 106 . When the process cartridge is installed in the image forming apparatus in the L direction, theforce receiving member 103 provided on the developingunit 100 presses the above-mentionedforce applying member 105 to the compressed position, where theforce applying member 105 moves in the N direction; After theprotrusion 107 on theforce member 105 passes over the above-mentionedforce receiving member 103, theforce applying member 105 is springed up by thespring 106 and engages with therecess 108 on theforce receiving member 103, and theforce applying member 105 moves in the M direction to receive the force by force. Themember 103 pushes the developingunit 100 to rotate, so that the developingroller 102 in the developingunit 100 is separated from thephotosensitive drum 104 in thedrum unit 101 . In the above technical solution, since the protruding portion on the force-applying member engages with the recessed portion of the force-receiving member in the developing unit, the force-applying member is likely to be stuck when pushing the developing unit to rotate. Because the force-applyingmember 105 in the imaging device needs to be compressed to be retracted, thespring 106 supporting the force-applyingmember 105 is always in a compressed state, which may easily cause the problem of inflexibility of thespring 106 to rebound, and thus cause the force-applyingmember 105 to fail to receive the force normally. Problems withmember 103 meshing.

如图3所示，为本实施例中处理盒1在设置有边盖6的一侧的分解结构示意图。本实施例将处理盒1在设置有驱动力接收构件9的一侧定义为驱动侧。显影框架包括边盖6、端盖8、护盖10和粉仓主体等。其中，端盖8、驱动力接收构件9以及护盖10都设置在显影单元2的驱动侧，具体的，端盖8固定至显影单元2的粉仓主体的一侧，驱动力接收构件9安装在端盖8上，护盖10套接着驱动力接收构件9并与端盖8相结合，且护盖10穿过边盖6上形成的通孔6a而被边盖6所支撑。本实施例中，力接收构件7具体设置在端盖8上，可选择的，也可将力接收构件7设置在护盖10上，或可将力接收构件7设置在显影单元2的框架上，只需满足力接收构件7接收外力后推动显影单元2旋转即可。为了便于下文描述，下面简要定义在本实施例中描述的方向，将处理盒1安装至成像设备中的重力方向定义为上下方向，处理盒1的纵向方向定义为前后方向，同时垂直于上下方向和左右方向的方向称为左右方向。As shown in FIG. 3 , a schematic diagram of an exploded structure of the process cartridge 1 on the side provided with theside cover 6 in this embodiment is shown. The present embodiment defines the side of the process cartridge 1 on which the drivingforce receiving member 9 is provided as the driving side. The developing frame includes aside cover 6 , anend cover 8 , aprotective cover 10 , a main body of the powder container, and the like. Theend cover 8 , the drivingforce receiving member 9 and theprotective cover 10 are all arranged on the driving side of the developingunit 2 . Specifically, theend cover 8 is fixed to one side of the main body of the toner container of the developingunit 2 , and the drivingforce receiving member 9 is installed On theend cover 8 , theprotective cover 10 is fitted over the drivingforce receiving member 9 and combined with theend cover 8 , and theprotective cover 10 is supported by theside cover 6 through the throughhole 6 a formed in theside cover 6 . In this embodiment, theforce receiving member 7 is specifically arranged on theend cover 8 , alternatively, theforce receiving member 7 can also be arranged on theprotective cover 10 , or theforce receiving member 7 can be arranged on the frame of the developingunit 2 , as long as theforce receiving member 7 receives the external force and pushes the developingunit 2 to rotate. For the convenience of the following description, the directions described in this embodiment are briefly defined below, the direction of gravity in which the process cartridge 1 is installed in the image forming apparatus is defined as the up-down direction, and the longitudinal direction of the process cartridge 1 is defined as the front-rear direction, while being perpendicular to the up-down direction and the left-right direction is called the left-right direction.

如图4所示，为本实施例中力接收构件7、端盖8和显影单元2的框架相互装配的示意图。其中，力接收构件7可活动地安装至端盖8上，具体的，端盖8上形成有第一限制部8a和第二限制部8b，第一限制部8a和第二限制部8b之间形成大致“倒八字”形状的容纳开口8c，力接收构件7两侧抵接着第一限制部8a和第二限制部8b而安置在容纳开口8c中，并可在容纳开口8c中上下移动。需要说明的是，本实施例中力接收构件7的第一侧面7b和第二侧面7c分别抵接着第一限制部8a、第二限制部8b，且第一侧面7b为一竖直面，第二侧面7c为一斜平面。当力接收构件7沿容纳开口8c向下移动时，由于容纳开口8c自上而下越来越窄（即第一限制部8a与第二限制部8b之间的距离越来越小），力接收构件7在容纳开口8c中的可活动空间逐渐变小，第一限制部8a、第二限制部8b逐渐夹紧力接收构件7而限制力接收构件7在容纳开口8c中的活动量（晃动量）；当力接收构件7沿容纳开口8c向上移动时，由于容纳开口8c自下而上越来越宽（即第一限制部8a与第二限制部8b之间的距离越来越大），力接收构件7在容纳开口8c中的可活动空间逐渐变大，力接收构件7在容纳开口8c中的活动量（晃动量）也会变大。还需说明的是，本实施例中力接收构件7的第一侧面7b和第二侧面7c与第一限制部8a、第二限制部8b之间的接触面是光滑的，即第一侧面7b和第二侧面7c与第一限制部8a、第二限制部8b之间的摩擦力很小，当力接收构件7在容纳开口8c中上下移动时，力接收构件7只需很小的向上作用力即可在容纳开口8c中向上移动，且力接收构件7由于自身重力即可在容纳开口8c中向下移动。As shown in FIG. 4 , it is a schematic diagram of the mutual assembly of the frame of theforce receiving member 7 , theend cover 8 and the developingunit 2 in this embodiment. Theforce receiving member 7 is movably mounted on theend cover 8. Specifically, theend cover 8 is formed with a first restricting portion 8a and a second restrictingportion 8b, between the first restricting portion 8a and the second restrictingportion 8b. Anaccommodating opening 8c is formed in a substantially "inverted figure" shape, and theforce receiving member 7 is seated in theaccommodating opening 8c against the first restricting portion 8a and the second restrictingportion 8b on both sides, and can move up and down in theaccommodating opening 8c. It should be noted that in this embodiment, thefirst side surface 7b and thesecond side surface 7c of theforce receiving member 7 are respectively abutted against the first restricting portion 8a and the second restrictingportion 8b, and thefirst side surface 7b is a vertical surface, and thefirst side surface 7b is a vertical surface. The twoside surfaces 7c are inclined planes. When theforce receiving member 7 moves downward along theaccommodating opening 8c, since theaccommodating opening 8c becomes narrower from top to bottom (ie, the distance between the first restricting portion 8a and the second restrictingportion 8b becomes smaller and smaller), the force receiving The movable space of themember 7 in theaccommodating opening 8c gradually becomes smaller, and the first restricting portion 8a and the second restrictingportion 8b gradually clamp theforce receiving member 7 to restrict the amount of movement (vibration amount) of theforce receiving member 7 in theaccommodating opening 8c. ); when theforce receiving member 7 moves upward along theaccommodating opening 8c, since theaccommodating opening 8c becomes wider and wider from bottom to top (that is, the distance between the first restricting portion 8a and the second restrictingportion 8b becomes larger and larger), the force The movable space of the receivingmember 7 in theaccommodating opening 8c gradually increases, and the amount of movement (vibration amount) of theforce receiving member 7 in theaccommodating opening 8c also increases. It should also be noted that in this embodiment, the contact surfaces between thefirst side 7b and thesecond side 7c of theforce receiving member 7 and the first restricting portion 8a and the second restrictingportion 8b are smooth, that is, thefirst side 7b The frictional force between thesecond side surface 7c and the first restricting portion 8a and the second restrictingportion 8b is very small, and when theforce receiving member 7 moves up and down in theaccommodating opening 8c, theforce receiving member 7 needs only a small upward action The force can move upward in theaccommodating opening 8c, and theforce receiving member 7 can move downward in theaccommodating opening 8c due to its own gravity.

可选择的，第一限制部8a还可以用于防止力接收构件7在接收施力构件105的分离力后相对于显影单元的框架发生旋转。具体的，在第一限制部8a上设置有一个朝向容纳力接收构件7的容纳部突出的突出部，该突出部设置为当力接收构件7接收外力而带动显影单元相对于鼓单元旋转时防止力接收构件7在容纳部滑动和松脱。Alternatively, the first restricting portion 8a may also serve to prevent theforce receiving member 7 from rotating relative to the frame of the developing unit after receiving the separation force of theforce applying member 105 . Specifically, a protruding portion protruding toward the accommodating portion of the accommodatingforce receiving member 7 is provided on the first restricting portion 8a. The protruding portion is configured to prevent the developing unit from rotating relative to the drum unit when theforce receiving member 7 receives an external force and drives the developing unit to rotate relative to the drum unit. Theforce receiving member 7 is slid and released in the receptacle.

本实施例中，力接收构件7上形成有一通孔7a，显影单元2的框架上形成有突起2a，当安置有力接收构件7的端盖8装配至显影单元2的框架上时，突起2a穿过力接收构件7的通孔7a而限制力接收构件7在容纳开口8c中的上下移动量，如此，力接收构件7不会从容纳开口8c中脱离。In this embodiment, a through hole 7a is formed on theforce receiving member 7, and a protrusion 2a is formed on the frame of the developingunit 2. When theend cap 8 on which theforce receiving member 7 is placed is assembled to the frame of the developingunit 2, the protrusion 2a penetrates The amount of up-and-down movement of theforce receiving member 7 in theaccommodating opening 8c is restricted by the through hole 7a of theforce receiving member 7, so that theforce receiving member 7 is not disengaged from theaccommodating opening 8c.

下面结合附图具体说明本实施例中力接收构件7与成像设备中的施力构件105配合而使显影辊4与感光鼓5相互分离的过程。The process in which theforce receiving member 7 and theforce applying member 105 in the image forming apparatus cooperate to separate the developingroller 4 and thephotosensitive drum 5 from each other in this embodiment will be specifically described below with reference to the accompanying drawings.

为了便于描述，将力接收构件7向下移动至一个可接收施力构件105的力的位置称为分隔力接收位置，将力接收构件7从上述分隔力接收位置向上移动至一个更靠上的位置称为撤回位置，力接收构7可在分隔力接收位置和撤回位置之间移动。如图5所示，为本实施例中处理盒1安装至成像设备中的示意图。当处理盒1向下安装至成像设备中时，处理盒1的力接收构件7与成像设备中施力构件105的突起部107相接触，由于力接收构件7是可活动地安装在端盖8上的，且只需一很小的向上作用力即可向上移动，因此施力构件105的突起部107可迫推力接收构件7向上移动至撤回位置，可以理解的是，成像设备中施力构件105是被弹簧106所支撑的，力接收构件7在弹簧106弹力作用下即可向上移动。此时，处理盒1的显影辊4与感光鼓5处于相互接触状态。For ease of description, moving theforce receiving member 7 downward to a position where it can receive the force of theforce applying member 105 is referred to as a separation force receiving position, and moving theforce receiving member 7 upward from the above separation force receiving position to a more upper position The position is referred to as the retracted position, between which the force-receivingmember 7 is moveable for the separation force-receiving position and the retracted position. As shown in FIG. 5 , it is a schematic diagram of the process cartridge 1 installed in the image forming apparatus in this embodiment. When the process cartridge 1 is mounted downward into the image forming apparatus, theforce receiving member 7 of the process cartridge 1 comes into contact with theprotrusion 107 of theforce applying member 105 in the image forming apparatus, since theforce receiving member 7 is movably mounted on theend cap 8 and only a small upward force is required to move upward, so the protrudingportion 107 of theforce applying member 105 can force thethrust receiving member 7 to move upward to the retracted position. It can be understood that the force applying member in theimaging device 105 is supported by aspring 106 , and theforce receiving member 7 can move upward under the elastic force of thespring 106 . At this time, the developingroller 4 of the process cartridge 1 and thephotosensitive drum 5 are in contact with each other.

如图6所示，为本实施例中处理盒1在成像设备中的第一状态示意图。当处理盒1已安装至成像设备中时，成像设备中的施力构件105向左移动，施力构件105的突起部107越过力接收构件7，即施力构件105在上下方向不再抵接着力接收构件7，施力构件105移动至力接收构件7的左侧位置，力接收构件7在自身重力作用下向下移动至分隔力接收位置，力接收构件7被第一限制部8a、第二限制部8b逐渐夹紧。此时，处理盒1的显影辊4与感光鼓5处于相互接触状态。As shown in FIG. 6 , it is a schematic diagram of the first state of the process cartridge 1 in the image forming apparatus in this embodiment. When the process cartridge 1 has been installed in the image forming apparatus, the urgingmember 105 in the image forming apparatus moves to the left, theprotrusion 107 of the urgingmember 105 goes over theforce receiving member 7, that is, the urgingmember 105 no longer abuts in the up-down direction Theforce receiving member 7, the urgingmember 105 is moved to the left position of theforce receiving member 7, theforce receiving member 7 is moved downward to the separation force receiving position under the action of its own gravity, and theforce receiving member 7 is limited by the first restricting portion 8a, The two restrictingportions 8b are gradually clamped. At this time, the developingroller 4 of the process cartridge 1 and thephotosensitive drum 5 are in contact with each other.

如图7所示，为本实施例中处理盒1在成像设备中的第二状态示意图。成像设备中的施力构件105向右移动，施力构件105的突起部107抵接力接收构件7的第一侧面7b，此时，第一侧面7b作为受力面，具体的将力接收构件7的第一侧面7b构造为在重力方向上延伸的一竖直面，施力构件105通过突起部107挤压第一侧面7b而向力接收构件7施加向右作用力，力接收构件7进而带动显影单元2旋转，显影辊4与感光鼓5逐渐分离。在该过程中，力接收构件7被第一限制部8a、第二限制部8b所夹紧，即使施力构件105在推动力接收构件7旋转的过程中产生向上作用力，力接收构件7也不会向上移动，始终保持与施力构件105的突起部107相互抵接的状态，使得处理盒1维持在显影辊4与感光鼓5相互分离状态。As shown in FIG. 7 , it is a schematic diagram of the second state of the process cartridge 1 in the image forming apparatus in this embodiment. The force-applyingmember 105 in the imaging device moves to the right, and the protrudingportion 107 of the force-applyingmember 105 abuts against thefirst side surface 7b of the force-receivingmember 7. At this time, thefirst side surface 7b serves as the force-receiving surface. Thefirst side surface 7b is configured as a vertical surface extending in the direction of gravity, the force-applyingmember 105 presses thefirst side surface 7b through theprotrusion 107 to exert a rightward force on the force-receivingmember 7, and the force-receivingmember 7 further drives theThe developing unit 2 rotates, and the developingroller 4 is gradually separated from thephotosensitive drum 5 . During this process, theforce receiving member 7 is clamped by the first restricting portion 8a, the second restrictingportion 8b, and even if theforce applying member 105 generates an upward force during the rotation of the pushingforce receiving member 7, theforce receiving member 7 is not The process cartridge 1 is maintained in a state in which the developingroller 4 and thephotosensitive drum 5 are separated from each other without moving upward, and the protrudingportion 107 of the urgingmember 105 is always kept in contact with each other.

And the downward elastic force exerted by the elastic member on theforce receiving member 7 is smaller than the upward elastic force exerted by thespring 106 on theforce applying member 105 , so that theforce receiving member 7 can move upward to the retracted position under the action of theforce applying member 105 .

优选的，为了使得力接收构件7与施力构件105配合并接收分隔力时更加稳定，在力接收构件7的受力面即第一侧面7b上设置一个防滑构件，具体的可以设置为一个海绵，海绵贴在该第一侧面7b上，突起部107在抵接上述海绵时，可以压迫海绵变形，突起部107与海绵接触的地方海绵会被压缩而自动凹入形成一个凹口，当突起部107在迫推力接收构件7移动时，由于突起部107与海绵上由于变形而形成的凹口配合不容易打滑，使得力接收构件7接收施力构件105的分隔力时更加稳定。防滑构件除了设置为为海绵也可以设置为其他形式，例如软性的塑胶和硅胶等。Preferably, in order to make the force-receivingmember 7 cooperate with the force-applyingmember 105 and receive the separation force more stably, a non-slip member, specifically a sponge, is provided on the force-receiving surface of the force-receivingmember 7 , that is, thefirst side 7b , the sponge is attached to thefirst side 7b, theprotrusion 107 can press the sponge to deform when theprotrusion 107 is in contact with the sponge, and the sponge will be compressed where theprotrusion 107 contacts the sponge and automatically concave to form a notch. 107 When thethrust receiving member 7 is forced to move, theprotrusion 107 and the notch formed by the deformation on the sponge are not easily slipped, so that theforce receiving member 7 is more stable when receiving the separating force of theforce applying member 105 . In addition to being configured as sponge, the anti-skid member can also be configured in other forms, such as soft plastic and silicone.

需要说明的是，在本实施例的描述中，术语“向上”、“向下”并不是指示或暗示所指的装置或元件必须具有的特定方位，即不仅仅指在竖直方向的“向上”、“向下”，可以理解的是，也可解释为相对竖直方向倾斜一定角度的“斜向上”、“斜向下”，在处理盒向成像设备中安装的过程中，力接收构件7的移动方式可以总结为：当处理盒安装至成像设备中时，力接收构件7可被施力构件105迫推而至少在重力方向上向上移动。It should be noted that, in the description of this embodiment, the terms "upward" and "downward" do not indicate or imply the specific orientation that the referred device or element must have, that is, not only refer to "upward" in the vertical direction ” and “downward”, it can be understood that it can also be interpreted as “oblique upward” and “slanted downward” inclined at a certain angle relative to the vertical direction. During the process of installing the process cartridge into the imaging device, the force receiving member The moving manner of 7 can be summarized as follows: when the process cartridge is mounted in the image forming apparatus, theforce receiving member 7 can be urged by the urgingmember 105 to move upward at least in the direction of gravity.

下面结合图12至图13说明本实施例中，力接收构件701与成像设备中的施力构件105啮合并接收分离力的过程。The process in which theforce receiving member 701 engages with theforce applying member 105 in the image forming apparatus and receives the separation force in this embodiment will be described below with reference to FIGS. 12 to 13 .

当处理盒安装入成像设备中，在显影单元的纵向方向，将力接收构件701的偏置位置设置成与成像设备中的施力构件105不重叠，因此，处理盒可以正常沿着与显影单元纵向方向垂直的左右方向顺畅安装入成像设备中，随着成像设备中的门盖的合上动作，设置在处理盒上的力接收组件20可接收成像设备中外力，具体的是成像设备中的内壁对受力杆21施加压力，受力杆21和控制杆22一同开始受力，由于受力杆21被肋板10a阻挡，因此控制杆22开始绕着圆形突出柱22c旋转，并通过施力面22d1操作力接收构件701向靠近成像设备中的施力构件105移动，此时，在显影单元的纵向方向上，施力构件105和力接收构件701的至少一部分是相互重叠的，因此，力接收构件701被施力构件105阻挡而停止在施力构件105的一侧，此时，控制杆22被来自成像设备内壁的力挤压而具有一定的变形量，当成像设备预转并驱动施力构件105向左移动（参见图6）时，在显影单元的纵向方向，施力构件105将会与力接收构件701解除重叠状态，利用控制杆22的弹性恢复可以迫使力接收构件701在纵向方向上继续移动一定行程使得施力构件105与力接收构件107在左右方向上重叠，力接收构件107可以接收施力构件105的分离力使得显影辊与感光鼓分离。当需要取出盒子时，随着成像设备中的门盖的开启，成像设备取消对力接收组件20的力，在回位弹簧23的弹力作用下，控制杆22沿着相反方向旋转回到预设的初始位置，控制杆22取消对力接收构件701的按压力，力接收构件701在偏置构件24的偏置力下回到偏置位置，处理盒可以顺畅取出。When the process cartridge is installed in the image forming apparatus, in the longitudinal direction of the developing unit, the offset position of theforce receiving member 701 is set so as not to overlap theforce applying member 105 in the image forming apparatus, and therefore, the process cartridge can be normally aligned with the developing unit along the The left and right directions perpendicular to the longitudinal direction are smoothly installed into the imaging device, and along with the closing action of the door cover in the imaging device, theforce receiving assembly 20 disposed on the process cartridge can receive the external force in the imaging device, specifically the force in the imaging device. The inner wall exerts pressure on the force-bearingrod 21, and the force-bearingrod 21 and thecontrol rod 22 begin to be stressed together. Since the force-bearingrod 21 is blocked by the rib 10a, thecontrol rod 22 starts to rotate around the circularprotruding column 22c, and is rotated by applying the force. The force surface 22d1 operates theforce receiving member 701 to move toward theforce applying member 105 in the image forming apparatus, and at this time, in the longitudinal direction of the developing unit, at least a part of theforce applying member 105 and theforce receiving member 701 overlap each other, and therefore, Theforce receiving member 701 is blocked by theforce applying member 105 and stops at one side of theforce applying member 105. At this time, thecontrol rod 22 is pressed by the force from the inner wall of the image forming apparatus and has a certain amount of deformation. When the image forming apparatus is pre-rotated and driven When the urgingmember 105 moves to the left (see FIG. 6 ), in the longitudinal direction of the developing unit, the urgingmember 105 will be released from the overlapping state with theforce receiving member 701 , and theforce receiving member 701 can be forced by the elastic recovery of thelever 22 in the longitudinal direction of the developing unit. Continuing the movement in the longitudinal direction for a certain stroke causes the urgingmember 105 to overlap theforce receiving member 107 in the left-right direction, and theforce receiving member 107 can receive the separation force of the urgingmember 105 to separate the developing roller from the photosensitive drum. When the box needs to be taken out, as the door cover in the imaging device is opened, the imaging device cancels the force on theforce receiving assembly 20, and under the elastic force of thereturn spring 23, thecontrol lever 22 rotates in the opposite direction to return to the preset When thecontrol lever 22 cancels the pressing force on theforce receiving member 701, theforce receiving member 701 returns to the biased position under the biasing force of the biasingmember 24, and the process cartridge can be taken out smoothly.

实施例3Example 3

接下来，接收本实用新型实施例3。本实施例中，将力接收构件702设置成可旋转移动的结构。Next, the third embodiment of the present invention is received. In this embodiment, theforce receiving member 702 is provided in a rotatably movable structure.

如图14和图15所示，粉仓主体11上设置有一个安装孔11b，力接收构件702上设置有可安装入所述安装孔11b内的旋转支撑部702a，力接收构件702通过旋转支撑部702a插入安装孔11b中可以相对于粉仓主体11旋转。在力接收构件702的分隔力接收一侧的侧面还贴有一个防滑构件7021，优选的，该防滑构件7021构造为海绵。As shown in Fig. 14 and Fig. 15 , a mountinghole 11b is provided on themain body 11 of the powder container, and theforce receiving member 702 is provided with arotating support portion 702a which can be mounted in the mountinghole 11b, and theforce receiving member 702 is rotatably supported by Theportion 702a is inserted into the mountinghole 11b so as to be rotatable relative to thecontainer body 11 . Ananti-slip member 7021 is also attached to the side of the force-receiving side of the force-receivingmember 702, and preferably, theanti-slip member 7021 is configured as a sponge.

如图16中（a）至（c）所示，当处理盒初始安装入成像设备中，随着成像设备的门盖的闭合，力接收构件702初始位于成像设备中的施力构件105的左侧，此时，力接收构件702可以处于一个与施力构件105分隔的位置，也可以与施力构件105有接触并被施力构件105压迫而向上旋转一定角度，随着成像设备的预转，施力构件105开始从右向左移动，在施力构件105从右向左移动的过程中，会迫推力接收构件702向上旋转，施力构件105越过向上旋转后的力接收构件702，最终如图16中（c）所示，施力构件105的施力部在力接收构件702的左侧，力接收构件702将会在自身重力的作用下向下旋转回到图16中（a）中位置，并与防滑构件7021接触，此位置时力接收构件702可以接收施力构件105的间隔力，当施力构件105被成像设备控制从图16中（c）中位置从左向右移动时，通过施力构件105对力接收构件702施加力使得显影辊与感光鼓分隔开。此种设置，可以使得力接收构件702被施力构件105迫推时更容易向上移动而避开与施力构件105的干涉。As shown in (a) to (c) of FIG. 16 , when the process cartridge is initially installed in the image forming apparatus, with the closing of the door cover of the image forming apparatus, theforce receiving member 702 is initially positioned to the left of theforce applying member 105 in the image forming apparatus At this time, theforce receiving member 702 may be in a position separated from theforce applying member 105, or may be in contact with theforce applying member 105 and be pressed by theforce applying member 105 to rotate upward by a certain angle, with the pre-rotation of the imaging device , the force-applyingmember 105 starts to move from right to left. During the process of the force-applyingmember 105 moving from right to left, thethrust receiving member 702 will be forced to rotate upward, and the force-applyingmember 105 will pass the upwardly rotatedforce receiving member 702, and finally As shown in FIG. 16( c ), the urging portion of the urgingmember 105 is on the left side of theforce receiving member 702 , and theforce receiving member 702 will rotate downward under the action of its own gravity and return to FIG. 16( a ) In this position, theforce receiving member 702 can receive the spacing force of theforce applying member 105, and when theforce applying member 105 is controlled by the imaging device to move from the position in FIG. 16(c) from left to right When the force is applied to theforce receiving member 702 by theforce applying member 105, the developing roller is spaced apart from the photosensitive drum. This arrangement can make it easier for theforce receiving member 702 to move upward when it is forcibly pushed by theforce applying member 105 to avoid interference with theforce applying member 105 .

优选的，为了使得力接收构件702在向上旋转后可以更加灵活的回到一个可以接收施力构件105的分隔力的力接收位置，可以在力接收构件702和粉仓主体11之间设置一个弹性构件26，利用弹性构件26的弹性力辅助力接收构件702向下旋转回到力接收位置。Preferably, in order to make the force-receivingmember 702 more flexibly return to a force-receiving position that can receive the separation force of the force-applyingmember 105 after the force-receivingmember 702 is rotated upward, an elastic force can be set between the force-receivingmember 702 and the powder binmain body 11 Themember 26 utilizes the elastic force of theelastic member 26 to assist the force-receivingmember 702 to rotate downwardly back to the force-receiving position.

以上各实施例中，力接收构件的移动方式可以总结为如下，力接收构件相对于显影框架具有一个可与成像设备中的施力构件接触并接收使得显影辊与感光鼓分离的间隔力的间隔力接收位置，以及一个与间隔力接收位置不同的避让位置，具体的，在上述避让位置和间隔力接收位置，力接收构件接收所述施力构件的分隔力的力接收部相对于与显影框架具有不同的位置，该不同的位置可以是在处理盒的纵向方向上的不同位置，也可以是在处理盒上下方向，也可以是同时在处理盒的纵向方向和上下方向都具有不同的位置，只要满足，在间隔力接收位置力接收构件可以与施力构件接触并接收分隔显影辊和感光鼓的力，在避让位置时允许施力构件可以自由左右移动即可。另外，由于在处理盒的驱动侧具有驱动力接收构件9，当驱动力接收构件9接收成像设备中的驱动力旋转时会产生一个大的扭矩使得显影辊靠近感光鼓，即使现有技术中在该驱动力接收构件9与显影单元中增阿离合结构也会产品一个扭矩，因此，将力接收构件702设置在处理盒的驱动侧可以用里一个较小的分隔力以克服上述使得显影辊靠近感光鼓的扭矩。In each of the above embodiments, the moving manner of the force receiving member can be summarized as follows, the force receiving member has an interval relative to the developing frame that can contact the force applying member in the image forming apparatus and receive an interval force that separates the developing roller from the photosensitive drum The force receiving position, and an escape position different from the spacer force receiving position, specifically, in the above-mentioned avoidance position and spacer force receiving position, the force receiving portion of the force receiving member receiving the spacer force of the force applying member is relative to the developing frame. have different positions, and the different positions can be different positions in the longitudinal direction of the process cartridge, or in the up and down direction of the process cartridge, or have different positions in both the longitudinal direction and the up and down direction of the process cartridge at the same time, As long as it is satisfied, the force receiving member can contact the urging member at the spaced force receiving position and receive the force separating the developing roller and the photosensitive drum, and the urging member can freely move left and right at the avoidance position. In addition, since the drivingforce receiving member 9 is provided on the driving side of the process cartridge, a large torque is generated when the drivingforce receiving member 9 receives the driving force in the image forming apparatus and rotates so that the developing roller is brought close to the photosensitive drum, even though in the prior art The drivingforce receiving member 9 and the increased clutch structure in the developing unit also generate a torque, therefore, arranging theforce receiving member 702 on the driving side of the process cartridge can use a smaller separation force to overcome the above-mentioned making the developing roller close to the Torque of the drum.

与现有技术相比，本实用新型实施例中处理盒的力接收构件在上下方向是可自由活动的，而在左右方向是被限制活动的，因此，当处理盒安装进成像设备中时，力接收构件可移动至与成像设备中的施力构件不相干涉的位置；当成像设备中的施力构件左右移动时，力接收构件可与施力构件配合使得处理盒的显影辊与感光鼓相互分离。解决了现有技术中成像设备中的施力构件在推动显影单元旋转时容易出现卡死的技术问题。Compared with the prior art, in the embodiment of the present invention, the force receiving member of the process cartridge is freely movable in the up-down direction, but restricted in the left-right direction. Therefore, when the process cartridge is installed in the image forming apparatus, The force receiving member can be moved to a position that does not interfere with the force applying member in the image forming apparatus; when the force applying member in the image forming apparatus moves left and right, the force receiving member can cooperate with the force applying member so that the developing roller of the process cartridge and the photosensitive drum separated from each other. The technical problem that the force-applying member in the prior art image forming apparatus is likely to be stuck when pushing the developing unit to rotate is solved.

以上实施例仅用以说明本实用新型的技术方案，而非对其限制；尽管参照前述实施例对本实用新型进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本实用新型各实施例技术方案的精神和范围。The above embodiments are only used to illustrate the technical solutions of the present utility model, but not to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it can still be used for the foregoing implementations. The technical solutions described in the examples are modified, or some technical features thereof are equivalently replaced; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
