Description

一种显影盒a developing cartridge 技术领域technical field
本发明涉及一种显影盒，尤其涉及一种显影盒的被检测单元。The present invention relates to a developing cartridge, in particular to a detected unit of the developing cartridge.
背景技术Background technique
现有技术的图像形成装置中(打印机、复印机和传真机等)广泛使用一种显影盒，这种显影盒含有计数机构，显影盒可拆卸地安装在图像形成装置上，通过图像形成装置的信息检测机构和显影盒上的计数机构相互作用，实现对安装到图像形成装置上的显影盒是否是新的显影盒的检测，从而确定显影盒的寿命。In the prior art image forming apparatuses (printers, copiers, facsimile machines, etc.), a developing cartridge is widely used, and this developing cartridge contains a counting mechanism. The detection mechanism interacts with the counting mechanism on the developing cartridge to detect whether the developing cartridge installed on the image forming apparatus is a new developing cartridge, thereby determining the life of the developing cartridge.
现有的显影盒的计数机构皆采用具有缺齿部的检测齿轮用来检测显影盒是否为新的，在检测过程中，检测齿轮的有齿部与驱动齿轮啮合，检测齿轮跟随驱动齿轮旋转完成检测，当检测完成时，检测齿轮的缺齿部与驱动齿轮相对，检测齿轮与驱动齿轮脱离啮合，检测齿轮不再跟随驱动齿轮旋转，具有缺齿部的检测齿轮制造及安装精度要求高，而且由于显影盒的检测齿轮包括缺齿部，因此在使用过程中可能会发生传动不稳定或失效的情况，这样将直接导致检测突起不能有效与打印机传感器触碰，从而造成误判。另一方面，显影盒的再次利用过程中，需要拆除显影盒端盖复位检测机构才能再次使用，直接影响回收效率。The counting mechanisms of the existing developing cartridges all use detection gears with missing teeth to detect whether the developing cartridges are new. During the detection process, the toothed parts of the detection gear mesh with the drive gear, and the detection gear follows the drive gear to complete the rotation. Detection, when the detection is completed, the missing tooth part of the detection gear is opposite to the driving gear, the detection gear is disengaged from the driving gear, the detection gear no longer rotates with the driving gear, and the detection gear with the missing tooth part requires high manufacturing and installation accuracy, and Since the detection gear of the developing cartridge includes a missing tooth, the transmission may become unstable or fail during use, which will directly cause the detection protrusion to fail to effectively contact the printer sensor, resulting in misjudgment. On the other hand, in the process of reusing the developing cartridge, it is necessary to remove the end cover reset detection mechanism of the developing cartridge before it can be used again, which directly affects the recycling efficiency.
发明内容SUMMARY OF THE INVENTION
本发明的目的是提供一种显影盒，以解决了现有技术中显影盒齿轮系布局不够灵活，影响显影盒的小型化设计的问题，为了解决上述技术问题，本发明是通过以下技术方案实现的：The purpose of the present invention is to provide a developing cartridge, so as to solve the problem that the layout of the gear train of the developing cartridge is not flexible enough in the prior art, which affects the miniaturization design of the developing cartridge. In order to solve the above technical problems, the present invention is realized by the following technical solutions of:
一种显影盒，可拆卸地安装至具有检测部件的图像形成装置中，所述显影盒包括：A developing cartridge is detachably mounted in an image forming apparatus having a detection part, the developing cartridge comprising:
壳体，其内可容纳显影剂；a housing in which the developer can be accommodated;
驱动力接收构件，接收所述图像形成装置输出的驱动力，可绕沿左右方向延伸的轴线旋转；a driving force receiving member that receives a driving force output from the image forming apparatus and is rotatable about an axis extending in the left-right direction;
检测单元，设置在所述壳体上的一侧，并被所述检测部件检测；a detection unit, arranged on one side of the casing, and detected by the detection component;
端盖，设置在所述壳体上的一侧；an end cover, arranged on one side of the casing;
所述检测单元包括连接齿轮、旋转组件以及滑动构件；所述连接齿轮和旋转组件可旋转的安装在所述壳体上，所述连接齿轮可以接收所述驱动力接收构件的驱动力并旋转，所述连接齿轮可以带动所述旋转组件旋转，所述旋转组件可在左右方向上相对所述连接齿轮移动；The detection unit includes a connecting gear, a rotating assembly and a sliding member; the connecting gear and the rotating assembly are rotatably mounted on the housing, the connecting gear can receive the driving force of the driving force receiving member and rotate, The connecting gear can drive the rotating assembly to rotate, and the rotating assembly can move relative to the connecting gear in the left-right direction;
所述旋转组件可以迫使所述滑动构件相对于所述端盖滑动，以使所述滑动构件接触或脱离所述检测部件。The rotation assembly may force the sliding member to slide relative to the end cap to bring the sliding member into contact with or disengage from the detection component.
上述本发明显影盒的技术方案，检测单元完成计数后，连接齿轮在驱动齿轮的驱动力作用下继续旋转，但计数齿轮的驱动力无法传递至旋转构件，使得旋转构件无法触动滑动构件，显影盒的工作稳定性能够得到有效保证。显影盒在回收利用时，只需使用外力重新调整旋转组件的初始位置即可，而不必拆除显影盒端盖，有效提高了回收的成本和效率。In the above technical solution of the developing cartridge of the present invention, after the detection unit completes the count, the connecting gear continues to rotate under the action of the driving force of the driving gear, but the driving force of the counting gear cannot be transmitted to the rotating member, so that the rotating member cannot touch the sliding member. The work stability can be effectively guaranteed. When the developing cartridge is recycled, it is only necessary to use an external force to readjust the initial position of the rotating assembly without removing the end cover of the developing cartridge, which effectively improves the cost and efficiency of recycling.

The external force is applied to the toggle member 423 to rotate in the detection direction. At this time, the rotary member 421 and the connecting gear 41 do not rotate, so that the toggle member 423 rotates in the detection direction relative to the connecting gear 41. When the first force receiving part 4236 indicates When the mark points to the indicating bump, the rotation is stopped. At this time, the detected unit is at the initial position, and the detected unit can receive the driving force of the input gear 2 to complete the detection again. The reset process does not need to remove the side cover of the developing cartridge, nor to rotate the detection gear, and the reset is simple and convenient.
本实施显影盒，被检测单元完成计数后，旋转构件中的拨动件由于第一弹性构件的迫推与连接齿轮脱离啮合，连接齿轮在输入齿轮的驱动力作用下继续旋转，但连接齿轮的驱动力无法传递至拨动件，使得拨动件无法触动滑动构件，显影盒的工作稳定性能够得到有效保证。显影盒在回收利用时，只需使用外力重新调整旋转组件的初始位置即可，而不必拆除显影盒端盖，复位简单方便，有效提高了回收效率，降低了回收成本。In this embodiment of the developing cartridge, after the detected unit completes the count, the toggle piece in the rotating member is disengaged from the connecting gear due to the forcible push of the first elastic member, and the connecting gear continues to rotate under the driving force of the input gear. The driving force cannot be transmitted to the toggle piece, so that the toggle piece cannot touch the sliding member, and the working stability of the developing cartridge can be effectively guaranteed. When the developing cartridge is recycled, it is only necessary to use external force to readjust the initial position of the rotating assembly without removing the end cover of the developing cartridge. The reset is simple and convenient, which effectively improves the recycling efficiency and reduces the recycling cost.

下面将结合附图，详细描述本实施被检测单元的检测过程。当传递齿轮15位于初始位置，旋转构件16上的限位柱162与传递齿轮15上的第一限位壁152抵接，导向柱161与第一护盖12上的初始限位部123抵靠并同时位于第一护盖12的平面121上；当传递齿轮15开始旋转时，第一限位壁152旋转离开限位柱162，检测体17不能接收来自传递齿轮15的驱动力，所以检测体17不能跟随传递齿轮15旋转；当传递齿轮15旋转预定角度后，第二限位壁153才与旋转构件16的限位柱162抵接，从而当传递齿轮15进一步旋转时，传递齿轮15可通过连接杆14带动检测体17一起旋转，此时导向柱161与平面121抵接并接收传递齿轮15传递的驱动力与检测体17一起旋转，检测体17与传递齿轮15一起以转速R1旋转，在检测体17以R1速度旋转时，检测体17可与图像形成装置中的检测单元接触并施加力至检测单元，检测单元受到检测体17的力后，会以速度N1旋转，图像形成装置中的控制单元(未示出)识别检测单元的旋转，输出信号，被检测部的突起171可设置为多个，沿着检测体17的周向间隔分布，当突起171设置为多个时，当沿着平面121旋转时，可多次与图像形成装置中的检测单元接触而迫使检测单元旋转，从而多次输出信号；当传递齿轮15带动检测体17进一步旋转，旋转构件16的导向柱161离开平面121与斜面122抵接，由于斜面122相对于平面121倾斜更靠近壳体1，旋转构件16失去稳定地支撑，此时弹性构件13施加弹性力至旋转构件16，迫使旋转构件16进一步沿斜面122 快速转动且同时检测体17朝向靠近第一护盖12一侧移动；限位柱162与传递齿轮15脱离啮合，由于弹性构件13的作用，旋转构件16的旋转速度R2大于传递齿轮15的旋转速度R1；此时，当检测体17跟随旋转构件16以速度R2旋转时，检测体17与图像形成装置中的检测单元接触并促使检测单元以速度N2旋转，图像形成装置中的控制单元(未示出)可识别检测单元的旋转的变化，并输出信号；从而图像形成装置可根据显影盒中检测体17的旋转变化而输出不同的信号，从而识别显影盒的具体型号；在本实施例中，当旋转构件16沿着斜面122转动时，检测体17一直与图像形成装置中的检测单元保持接触。在本实施例中R2大于R1；当旋转构件16的导向柱161旋转离开斜面122时，旋转构件16停止旋转，检测体17停止旋转，旋转构件16的导向柱161与终止限位部124抵接并且限位在终止位置；此时旋转构件16的限位柱162完全脱离了传递齿轮15的凹槽151，从而不会与第一限位壁152和第二限位壁153接触，当传递齿轮15继续接收传递齿轮15传递的驱动力而持续旋转时，旋转构件16因与传递齿轮15脱离啮合，检测体17也不会再与旋转构件16一起旋转而停止在终止位置，从而检测体17完成检测。The detection process of the detected unit in this implementation will be described in detail below with reference to the accompanying drawings. When the transmission gear 15 is at the initial position, the limiting post 162 on the rotating member 16 abuts against the first limiting wall 152 on the transmission gear 15 , and the guide post 161 abuts against the initial limiting portion 123 on the first protective cover 12 and at the same time on the plane 121 of the first protective cover 12; when the transmission gear 15 starts to rotate, the first limit wall 152 rotates away from the limit post 162, and the detection body 17 cannot receive the driving force from the transmission gear 15, so the detection body 17 cannot follow the rotation of the transmission gear 15; when the transmission gear 15 rotates by a predetermined angle, the second limit wall 153 abuts the limit post 162 of the rotating member 16, so that when the transmission gear 15 rotates further, the transmission gear 15 can pass through. The connecting rod 14 drives the detection body 17 to rotate together. At this time, the guide column 161 is in contact with the plane 121 and receives the driving force transmitted by the transmission gear 15 to rotate together with the detection body 17. The detection body 17 rotates with the transmission gear 15 at the rotational speed R1. When the detection body 17 rotates at the speed of R1, the detection body 17 can contact the detection unit in the image forming apparatus and apply force to the detection unit. After the detection unit receives the force of the detection body 17, it will rotate at the speed N1, and the detection unit in the image forming apparatus The control unit (not shown) recognizes the rotation of the detection unit, and outputs a signal. The protrusions 171 of the detected portion may be provided in plural and distributed at intervals along the circumferential direction of the detection body 17. When the plane 121 rotates, it can contact the detection unit in the image forming apparatus for many times to force the detection unit to rotate, so as to output signals many times; when the transmission gear 15 drives the detection body 17 to rotate further, the guide column 161 of the rotating member 16 leaves the plane 121 is in contact with the inclined surface 122. Since the inclined surface 122 is inclined and closer to the housing 1 relative to the plane 121, the rotating member 16 loses its stable support. At this time, the elastic member 13 applies elastic force to the rotating member 16, forcing the rotating member 16 to further along the inclined surface 122. Rapidly rotate and at the same time the detection body 17 moves toward the side close to the first cover 12 ; the limit post 162 is disengaged from the transmission gear 15 , due to the action of the elastic member 13 , the rotational speed R2 of the rotating member 16 is greater than the rotational speed of the transmission gear 15 R1; at this time, when the detection body 17 follows the rotation member 16 to rotate at the speed R2, the detection body 17 contacts the detection unit in the image forming apparatus and causes the detection unit to rotate at the speed N2, and the control unit (not shown) in the image forming apparatus out) can identify the change of the rotation of the detection unit, and output a signal; thus the image forming device can output different signals according to the rotation change of the detection body 17 in the developing cartridge, thereby identifying the specific model of the developing cartridge; in this embodiment, When the rotating member 16 is rotated along the inclined surface 122, the detection body 17 is kept in contact with the detection unit in the image forming apparatus. In this embodiment, R2 is greater than R1; when the guide column 161 of the rotating member 16 rotates away from the inclined surface 122, the rotating member 16 stops rotating, the detection body 17 stops rotating, and the guide column 161 of the rotating member 16 abuts against the stop limit portion 124 And the limit is at the end position; at this time, the limit post 162 of the rotating member 16 is completely separated from the groove 151 of the transmission gear 15, so as not to contact the first limit wall 152 and the second limit wall 153, when the transmission gear When the 15 continues to receive the driving force transmitted by the transmission gear 15 and continues to rotate, the rotating member 16 is disengaged from the transmission gear 15, and the detection body 17 will no longer rotate together with the rotating member 16 and stop at the end position, so that the detection body 17 is completed. detection.

When the rotating member moves along the inclined surface, under the action of the elastic force of the elastic member, the rotation speed of the rotating member along the inclined surface is faster than the detection speed. The rotation speed of the component along the plane, the rotating component drives the detection body to rotate through the connecting rod; by setting a plane and an inclined plane on the cover, the rotation speed of the detection body is changed, and in the process of accelerated rotation of the detection body, the image is formed.

下面将结合附图，详细描述本发明被检测单元的检测过程。当检测体位于初始位置，检测体85上的限位柱856与旋转构件84上的第一限位壁842抵接，导向柱853与边盖81上的初始限位部813抵靠并同时位于边盖81的平面811上； 当传递齿轮7开始旋转时，第一限位壁842旋转离开限位柱856，检测体85不能接收来自传递齿轮7的驱动力，所以检测体85不能跟随传递齿轮15旋转；当传递齿轮7旋转预定角度后，第二限位壁843才与检测体85的限位柱856抵接，从而当传递齿轮7进一步旋转时，传递齿轮7可通过连接杆83带动旋转构件84一起旋转，此时导向柱853与平面811抵接并接收旋转构件84传递的驱动力带动检测体85一起旋转，检测体85与旋转构件84一起以转速R1旋转，在检测体85以R1速度旋转时，检测体85可与接触构件88的触发端881接触并带动接触构件88沿滑轨818移动，此时，接触构件88的接触端882与图像形成装置中的检测单元接触并施加力至检测单元，检测单元受到检测体85的力后，会以速度N1旋转，图像形成装置中的控制单元(未示出)识别检测单元的旋转，输出信号，当突起855设置为多个时，当沿着平面811旋转时，接触构件88可多次与图像形成装置中的检测单元接触而迫使检测单元旋转，从而多次输出信号；当传递齿轮7带动检测体85进一步旋转，检测体85的导向柱853离开平面811与斜面812抵接，由于斜面812相对于平面811更靠近壳体1倾斜，检测体85失去稳定地支撑，此时第一弹性构件82施加弹性力至检测体，迫使检测体85进一步沿斜面812快速转动且同时检测体85朝向靠近边盖81一侧移动；限位柱856与旋转构件84脱离啮合，由于弹性构件84的作用，检测体85的旋转速度R2大于传递齿轮7的旋转速度R1；此时，当检测体85以速度R2旋转，检测体85与与接触构件88的触发端881接触并带动接触构件88沿滑轨818移动，接触构件88的接触端882与图像形成装置中的检测单元接触并促使检测单元以速度N2旋转，图像形成装置中的控制单元(未示出)可识别检测单元的旋转的变化，并输出信号；从而图像形成装置可根据显影盒中接触构件88的移动变化而输出不同的信号，从而识别显影盒的具体型号；在本实施例中，当检测体85沿着斜面812转动时，接触构件88一直与图像形成装置中的检测单元保持接触。在本实施例中R2大于R1；当检测体85的导向柱853旋转离开斜面812时，检测体85停止旋转，检测体85的导向柱853与终止限位部814抵接并且限位在终止位置；此时检测体85的限位柱856完全脱离了旋转构件84的凹槽841，从而不会与第一限位壁842和第二限位壁843接触，当旋转构件84继续接收传递齿 轮7传递的驱动力而持续旋转时，检测体85因与旋转构件84脱离啮合，检测体85也不会再与旋转构件84一起旋转而停止在终止位置，接触构件88不再移动，从而完成检测。The detection process of the detected unit of the present invention will be described in detail below with reference to the accompanying drawings. When the detection body is at the initial position, the limit post 856 on the detection body 85 abuts against the first limit wall 842 on the rotating member 84 , and the guide post 853 abuts against the initial limit portion 813 on the side cover 81 and is located at the same time. On the plane 811 of the side cover 81; when the transmission gear 7 starts to rotate, the first limit wall 842 rotates away from the limit post 856, and the detection body 85 cannot receive the driving force from the transmission gear 7, so the detection body 85 cannot follow the transmission gear. 15 rotation; when the transmission gear 7 rotates by a predetermined angle, the second limit wall 843 abuts the limit post 856 of the detection body 85, so that when the transmission gear 7 rotates further, the transmission gear 7 can be driven to rotate by the connecting rod 83 The member 84 rotates together. At this time, the guide column 853 is in contact with the plane 811 and receives the driving force transmitted by the rotating member 84 to drive the detection body 85 to rotate together. When the speed rotates, the detection body 85 can contact the trigger end 881 of the contact member 88 and drive the contact member 88 to move along the slide rail 818. At this time, the contact end 882 of the contact member 88 is in contact with the detection unit in the image forming apparatus and exerts a force To the detection unit, after the detection unit receives the force of the detection body 85, it will rotate at the speed N1, and the control unit (not shown) in the image forming apparatus recognizes the rotation of the detection unit, and outputs a signal. When rotating along the plane 811 , the contact member 88 can contact the detection unit in the image forming apparatus for many times to force the detection unit to rotate, thereby outputting signals multiple times; when the transmission gear 7 drives the detection body 85 to rotate further, the detection body 85 The guide post 853 leaves the plane 811 and abuts against the inclined plane 812. Since the inclined plane 812 is inclined closer to the housing 1 than the plane 811, the detection body 85 loses its stable support. At this time, the first elastic member 82 applies an elastic force to the detection body, forcing the detection body.

When the speed rotates, the detection body 95 can come into contact with the trigger end 981 of the contact member 98 and drive the contact member 98 to rotate around the rotation axis 983. At this time, the contact end 982 of the contact member 98 is in contact with the detection unit in the image forming apparatus and exerts a force To the detection unit, after the detection unit receives the force of the detection body 95, it will rotate at the speed N1, the control unit (not shown) in the image forming apparatus recognizes the rotation of the detection unit, and outputs a signal. When rotated along the plane 911 , the contact member 98 can contact the detection unit in the image forming apparatus for many times to force the detection unit to rotate, thereby outputting signals multiple times; when the transmission gear 7 drives the detection body 95 to rotate further, the detection body 95 The guide post 953 leaves the plane 911 and abuts against the inclined plane 912. Since the inclined plane 912 is inclined closer to the housing 1 than the plane 911, the detection body 95 loses its stable support. At this time, the first elastic member 92 applies an elastic force to the detection body, forcing the detection body. The body 95 further rotates rapidly along the inclined plane 912 and at the same time the detection body 95 moves towards the side close to the side cover 91; the limit post 956 is disengaged from the rotating member 94, due to the action of the elastic member 94, the rotation speed R2 of the detection body 95 is greater than the transmission gear At this time, when the detection body 95 rotates at the speed R2, the detection body 95 contacts with the trigger end 981 of the contact member 98 and drives the contact member 98 to rotate around the rotation axis 983, and the contact end 982 of the contact member 98 and The detection unit in the image forming apparatus contacts and causes the detection unit to rotate at a speed N2, and a control unit (not shown) in the image forming apparatus can recognize the change in the rotation of the detection unit and output a signal; thus the image forming apparatus can The movement of the middle contact member 98 changes to output different signals, thereby identifying the specific model of the developing cartridge; in this embodiment, when the detection body 95 rotates along the slope 912, the contact member 98 is always in contact with the detection unit in the image forming apparatus. Keep in touch. In this embodiment, R2 is greater than R1; when the guide column 953 of the detection body 95 rotates away from the inclined surface 912, the detection body 95 stops rotating, and the guide column 953 of the detection body 95 abuts against the stop limit portion 914 and stops at the stop position At this time, the limit post 956 of the detection body 95 is completely separated from the groove 941 of the rotating member 94, so as not to contact the first limit wall 942 and the second limit wall 943, when the rotating member 94 continues to receive the transmission gear 7 When the transmitted driving force continues to rotate, the detection body 95 is disengaged from the rotating member 94, the detection body 95 does not rotate together with the rotating member 94, and stops at the end position, and the contact member 98 stops moving, thereby completing the detection.
