Description
技术领域technical field
本发明涉及一种可拆卸的安装在图像形成装置中的碳粉盒。The invention relates to a toner cartridge detachably installed in an image forming device.
背景技术Background technique
现有技术公开了一种碳粉盒,碳粉盒是可拆卸的安装在图像形成装置中,其中碳粉盒包括显影辊和感光元件,显影辊与感光元件接触并将碳粉转运到感光元件的表面,因此感光元件的表面上形成碳粉图像。The prior art discloses a toner cartridge, which is detachably installed in an image forming device, wherein the toner cartridge includes a developing roller and a photosensitive element, and the developing roller contacts the photosensitive element and transfers the toner to the photosensitive element surface, so a toner image is formed on the surface of the photosensitive element.
在传统的激光打印机中,碳粉盒可拆卸的安装在其中,这种类型的打印机提供有检测装置,用于检测安装在激光打印机中的碳粉盒是否是新产品。In a conventional laser printer, the toner cartridge is detachably installed therein. This type of printer is provided with a detection device for detecting whether the toner cartridge installed in the laser printer is a new product.
例如,美国专利US20110243578公开了一种碳粉盒,其中碳粉盒的侧壁上设置有支撑检测齿轮的斜坡面,当检测齿轮接收驱动力旋转的过程中可沿着斜坡面运动从而在轴向方向上相对碳粉盒侧壁向外伸出或向内缩进,在检测齿轮向外伸出的过程中,设置在检测齿轮上的检测凸起拨动图像形成装置中的检测臂,并产生一个ON-OFF信号,根据此信号图像形成装置的CPU即可判断此碳粉盒是未用过的。由于以上专利公开的碳粉盒检测齿轮在接受驱动力旋转的过程中同时沿着支撑检测齿轮的斜坡面轴向伸缩,导致检测齿轮与传动齿轮之间啮合不平稳,进而影响碳粉盒的打印质量。For example, U.S. Patent US20110243578 discloses a toner cartridge, wherein the side wall of the toner cartridge is provided with a slope surface supporting the detection gear. When the detection gear receives the driving force and rotates, it can move along the slope surface so that In the direction relative to the side wall of the toner cartridge, it protrudes outward or retracts inward. During the process of the detection gear protruding outward, the detection protrusion arranged on the detection gear moves the detection arm in the image forming device and generates An ON-OFF signal, according to this signal, the CPU of the image forming device can judge that the toner cartridge is unused. Since the toner cartridge detection gear disclosed in the above patents expands and contracts axially along the slope surface supporting the detection gear while receiving the driving force and rotates, the meshing between the detection gear and the transmission gear is not smooth, which in turn affects the printing of the toner cartridge quality.
发明内容Contents of the invention

The detection protrusion is provided with a guide post, the detection gear is provided with a guide hole for accommodating the guide post, and the elastic element is installed in the guide hole of the detection gear and sleeved on the detection protrusion on the guide column.
所述检测凸起上设置有导向面。The detection protrusion is provided with a guide surface.
所述导向面是弧形面。The guide surface is an arc surface.
所述碳粉盒还包括限制所述检测凸起导向柱轴向运动的限制部件。The toner cartridge also includes a limiting component that limits the axial movement of the detection protrusion guide post.
所述限制部件为卡簧。The restricting part is a snap spring.
所述弹性元件为压缩弹簧。The elastic element is a compression spring.
在采用上述技术方案后,由于碳粉盒的检测凸起可相对检测齿轮在平行于显影辊轴向方向上向外伸出或向内缩进,不影响检测齿轮与传动齿轮之间的平稳啮合传动,当碳粉盒在装入图像形成装置后,碳粉盒的检测凸起在弹簧的作用下伸出并进入图像形成装置容纳检测臂的凹部中,检测凸起在随检测齿轮一起转动的过程中会拨动检测臂,从而达到图像形成装置检测装入其中的碳粉盒是否是未用过的目的,此方案工艺简单,解决了现有技术碳粉盒检测齿轮在轴向伸缩导致检测齿轮与传动齿轮之间的啮合不平稳致使碳粉盒的打印质量低劣技术问题。After adopting the above technical solution, since the detection protrusion of the toner cartridge can protrude outward or retract inward relative to the detection gear in the direction parallel to the axial direction of the developing roller, the smooth meshing between the detection gear and the transmission gear will not be affected. Transmission, when the toner cartridge is loaded into the image forming device, the detection protrusion of the toner cartridge will protrude under the action of the spring and enter the concave part of the image forming device to accommodate the detection arm, and the detection protrusion will rotate with the detection gear. During the process, the detection arm will be toggled, so as to achieve the purpose of the image forming device detecting whether the toner cartridge loaded therein is unused. This solution has a simple process and solves the problem of detection caused by the expansion and contraction of the toner cartridge detection gear in the prior art. The poor print quality of the toner cartridge is caused by the uneven meshing between the gears and the drive gear Technical issues.

Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
如图1,图2,图9和图10所示,图像形成装置20包括左右相对的第一侧壁22和第二侧壁23,其中第一侧壁22包括内壁22a和容纳检测臂21的凹部22b。As shown in Fig. 1, Fig. 2, Fig. 9 and Fig. 10, the
如图2与图6所示,碳粉盒1包括左右相对的第一侧壁13A和第二侧壁(图中未示出)以及可旋转支撑在两侧壁之间的显影辊3,显影辊3的末端套接有由导电材料做成的电极4,其中粉仓12存储碳粉,齿轮系安装在碳粉盒的第一侧壁13A上由设置在驱动头2上的输入齿轮2a,显影辊齿轮14,送粉辊齿轮15,第一惰轮9,搅拌架齿轮10,第二惰轮11和检测齿轮5组成,检测齿轮5上设置有无齿部分5a,有齿部分5b和导向孔5c,其中输入齿轮2a同时与显影辊齿轮14,送粉辊齿轮15和第一惰轮9啮合,第一惰轮9和第二惰轮11均为直径外大内小的双联齿轮,第一惰轮9的外部齿轮9a与输入齿轮2a啮合,其内部齿轮9b与搅拌架齿轮10啮合,第二惰轮11的内部齿轮11b与搅拌架齿轮10啮合,其外部齿轮11a与检测齿轮5啮合,如图3至图5所示,其中碳粉盒1还包括与检测凸起6配合的弹簧7和卡簧8,其中检测凸起6包括导向柱6a和圆弧形的导向面6c,导向柱6a上设置有圆形缺口6d和阶梯台6b,检测凸起6的导向柱6a与检测齿轮5的导向孔5c配合,弹簧7安装在检测齿轮5的导向孔5c内并套接在检测凸起6的导向柱6a上,弹簧7的一端与检测凸起6的阶梯台6b抵接,卡簧8卡在检测凸起6的圆形缺口6d内防止检测凸起6从检测齿轮5的导向孔5c内脱落。As shown in Figures 2 and 6, the toner cartridge 1 includes left and right opposite first side walls 13A and second side walls (not shown in the figure) and a developing
当碳粉盒1沿着F方向装入图像形成装置20的过程中,在最初阶段,如图7至图8所示,在碳粉盒1的检测凸起6接触图像形成装置20的内壁22a时,由于检测凸起6的导向面6c与图像形成装置20的内壁22a过盈接触,因此图像形成装置20的内壁22a迫推检测凸起6沿着平行于显影辊3轴向方向相对检测齿轮5在R方向上向内缩进,此时弹簧7处于压缩状态。When the toner cartridge 1 is loaded into the
当碳粉盒1完全装入图像形成装置20后(如图9所示),检测凸起6在弹簧7的作用下在平行于显影辊3轴向方向相对检测齿轮5在L方向上向外伸出,检测凸起6进入图像形成装置20容纳检测臂21的凹部22b中,并且检测凸起6沿着C方向从如图9所示的初始位置旋转到如图10所示的最终位置的过程中会触碰图像形成装置20的检测臂21,当启动图像形成装置20,碳粉盒1的驱动头2接受图像形成装置20的驱动力并将驱动力传递至检测齿轮5,由于检测齿轮5包括无齿部分5a和有齿部分5b,因此在最初阶段如图11所示,第二惰轮11与检测齿轮5的有齿部分5b啮合从而带动检测凸起6旋转,当检测凸起6运动到如图12所示的位置,检测凸起6触碰图像形成装置20的检测臂21并产生一个ON-OFF信号,从而图像形成装置20的CPU根据接收到的ON-OFF信号即可判断此碳粉盒1是新碳粉盒,当第二惰轮11带动检测齿轮5继续转动到如图13所示的位置,此时检测齿轮5的无齿部分5a与第二惰轮11相对,动力传输中止,检测凸起6停止在如图13所示的位置。When the toner cartridge 1 is fully loaded into the image forming device 20 (as shown in FIG. 9 ), the
当碳粉盒1沿着D方向从图像形成装置20中拆出的时候(如图10所示),碳粉盒1在拆出的过程中检测凸起6的导向面6c会过盈接触图像形成装置20的内壁22a,因此图像形成装置20的内壁22a迫推检测凸起6压缩弹簧7相对检测齿轮5在平行于显影辊3的轴向方向上向内缩回,碳粉盒1即可轻松的从图像形成装置20中拆出。When the toner cartridge 1 is removed from the
由于碳粉盒1在装入图像形成装置20或从图像形成装置20拆出的过程中,检测凸起6会相对检测齿轮5向内缩进,从而利于碳粉盒1的装入和拆出,当碳粉盒1完全装入图像形成装置20后,检测凸起6会相对检测齿轮5向外伸出进入图像形成装置20容纳检测臂21的凹部22b中,因此检测凸起6同检测齿轮5逆时针旋转过程中会触碰检测臂21,从而图像形成装置20的CPU接收一个ON/OFF信号,即可判断此碳粉盒1是未用过的。由于检测齿轮5并不是相对碳粉盒1的第一侧壁13A向外伸出或向内缩进,因此并不影响检测齿轮5与第二惰轮11之间的平稳啮合传动,保证了碳粉盒1的打印质量。Since the toner cartridge 1 is loaded into the
