由于第一安装孔32的轴向与X方向平行,因此,显影元件的旋转轴61的第一端部是沿与第一安装孔的轴向倾斜的方向插入到第一安装孔32中,所以,第一安装孔32的孔径需大于显影元件的旋转轴61的第一端部61b的外径,第二安装孔33的孔径大于第二端部61a的外径,以便于显影元件6的安装。但是,这样会导致安装到显影盒3上的显影元件在旋转的过程中会产生晃动,进而影响处理盒的显影质量。为了解决该问题,本实施例的处理盒1还包括固定在第一安装孔32外侧的定位件9和固定在第二安装孔33外侧的安装板8,定位件9具有可穿设在第一端部61b上的第一支撑孔92,安装板8具有可穿设在第二端部61a上的第二支撑孔81,第一支撑孔92的孔径与第一端部61b的外径大小匹配,第二支撑孔81的孔径与第二端部61a的外径大小匹配。也就是说,第一端部61b从第一安装孔32穿出至第一支撑孔92中,第二端部61a从第二安装孔33穿出至第二支撑孔81中。Since the axial direction of the first mounting hole 32 is parallel to the X direction, the first end portion of the rotating shaft 61 of the developing member is inserted into the first mounting hole 32 in a direction inclined to the axial direction of the first mounting hole, so The diameter of the first mounting hole 32 needs to be larger than the outer diameter of the first end portion 61b of the rotating shaft 61 of the developing member, and the diameter of the second mounting hole 33 is larger than the outer diameter of the second end portion 61a to facilitate the mounting of the developing member 6. . However, this causes the developing member mounted on the developing cartridge 3 to sway during the rotation, thereby affecting the developing quality of the process cartridge. In order to solve the problem, the process cartridge 1 of the present embodiment further includes a positioning member 9 fixed to the outside of the first mounting hole 32 and a mounting plate 8 fixed to the outside of the second mounting hole 33, and the positioning member 9 has a first position The first support hole 92 on the end portion 61b, the mounting plate 8 has a second support hole 81 pierceable on the second end portion 61a, and the aperture of the first support hole 92 matches the outer diameter of the first end portion 61b. The aperture of the second support hole 81 matches the outer diameter of the second end portion 61a. That is, the first end portion 61b passes out from the first mounting hole 32 into the first support hole 92, and the second end portion 61a passes out from the second mounting hole 33 into the second support hole 81.
参照图4至图6所示,定位件9具体包括:定位凸起93和定位部,定位凸起93凸向显影元件旋转轴61的轴向,定位凸起93上开设有第一支撑孔92,第一支撑孔92的孔径与显影元件的旋转轴61的第一端部61b的外径基本相同。定位部位于定位凸起93的根部外侧,定位部与第一安装孔32外侧连接。Referring to FIG. 4 to FIG. 6 , the positioning member 9 specifically includes a positioning protrusion 93 and a positioning portion. The positioning protrusion 93 protrudes in the axial direction of the rotating shaft 61 of the developing member, and the positioning protrusion 93 defines a first supporting hole 92. The aperture of the first support hole 92 is substantially the same as the outer diameter of the first end portion 61b of the rotary shaft 61 of the developing member. The positioning portion is located outside the root of the positioning protrusion 93, and the positioning portion is connected to the outside of the first mounting hole 32.
在定位部上设有沿旋转轴61轴向方向的第一卡扣91,第二壳体31上对应第一卡扣91的位置设有卡孔36。也就是说,第一卡扣91可匹配卡合在卡孔36内。当第一端部61b连接在第一支撑孔92内时,此时第一卡扣91卡合在卡孔36内,从而将定位件9固定在第二壳体31上。当将显影元件6安装到第二壳体31上之后,显影元件的旋转轴61的第一端部 61b穿过第一安装孔32,并伸出到第一安装孔32之外,然后,将定位件9安装到第二壳体31上,并使定位件9的第一支撑孔92套在显影元件的旋转轴61的第一端部61b,定位件9的第一卡扣91扣在第一安装孔32外部的卡孔36上,从而使定位件9与第二壳体31固定连接,显影元件的旋转轴61的第一端部61b通过定位件9被定位。The positioning portion is provided with a first buckle 91 along the axial direction of the rotating shaft 61, and the second housing 31 is provided with a card hole 36 at a position corresponding to the first buckle 91. That is, the first buckle 91 can be fitted into the card hole 36. When the first end portion 61b is connected in the first support hole 92, the first buckle 91 is engaged in the card hole 36 at this time, thereby fixing the positioning member 9 to the second housing 31. After the developing member 6 is mounted on the second housing 31, the first end of the rotating shaft 61 of the developing member 61b passes through the first mounting hole 32 and protrudes out of the first mounting hole 32. Then, the positioning member 9 is mounted on the second housing 31, and the first supporting hole 92 of the positioning member 9 is placed on the developing portion.

A positioning groove 94 is formed between the inner edge of the annular ring 90 and the outer edge of the positioning protrusion 93. The first buckle 91 is disposed on the groove wall of the positioning groove 94. The outer side of the first mounting hole 32 is provided with an end protrusion 32a, and the end protrusion 32a can be engaged in the positioning groove 94. That is, when the first end portion 61b of the rotating shaft 61 is supported in the first supporting hole 92, the end projection 32a is matched and coupled in the positioning groove 94, and at this time, the first buckle 91 is engaged with the card. In the hole 36. By the engagement of the positioning groove 94 and the end projection 32a, the connection between the positioning member 9 and the second housing 31 can be made more stable. Preferably, the number of the first buckles 91 may be one or more. When the first buckles 91 are plural, the first buckles 91 may be arranged along the circumferential direction of the annular ring 90, and the card holes are arranged. The number of the first buckles and the number of the first buckles 91 are not limited, and the specific number can be set according to actual needs.
较为优选的,该环形圈90内缘的尺寸与该端部凸起32a的外缘尺寸相同。定位凸起93的外缘尺寸与第一安装孔32的内孔壁尺寸相同。即,即当定位件9连接在第一安装孔外侧后,定位凸起93的外壁与第一安装孔32的内壁匹配贴合,第一端部61b的外壁与第一支撑孔92的内壁匹配贴合,端部凸起32a的外壁与环形圈90的内缘匹配贴合,从而进一步保证了显影元件6在旋转过程中的稳定性。More preferably, the inner edge of the annular ring 90 has the same size as the outer edge of the end projection 32a. The outer edge of the positioning projection 93 has the same size as the inner wall of the first mounting hole 32. That is, when the positioning member 9 is connected to the outside of the first mounting hole, the outer wall of the positioning protrusion 93 is matched with the inner wall of the first mounting hole 32, and the outer wall of the first end portion 61b matches the inner wall of the first supporting hole 92. In conformity, the outer wall of the end projection 32a fits snugly with the inner edge of the annular ring 90, thereby further ensuring the stability of the developing member 6 during rotation.
在本实施例中,参照图4所示,在第二壳体31设置有第二安装孔33的一侧设置有一个安装板8,安装板8设置在第二安装孔33的轴向外侧,用于可旋转的支撑显影元件6、第一传动齿轮11和第二传动齿轮12。In the present embodiment, as shown in FIG. 4, a mounting plate 8 is disposed on a side of the second housing 31 on which the second mounting hole 33 is disposed, and the mounting plate 8 is disposed on the outer side of the second mounting hole 33 in the axial direction. It is used to rotatably support the developing member 6, the first transfer gear 11, and the second transfer gear 12.
安装板8上设置有定位柱82,定位柱82上设置有第二支撑孔81,第二支撑孔81的孔径与显影元件6的旋转轴61的第二端部61a的外径基本相同。定位柱82的外径与第二安装孔33的内径匹配,当将安装板8沿X方向的反向安装到第二壳体31上时,定位柱82沿X方向的反向插入到第二安装孔33内,定位柱82的第二支撑孔81套在显影元件6的旋转轴61 的第二端部61a上,使显影元件的旋转轴61的第二端部61a可旋转的支撑在安装板8上,然后通过螺钉、粘贴、焊接等方式将安装板8与第二壳体31固定连接,显影元件的旋转轴6的第二端部61a被定位。The mounting plate 8 is provided with a positioning post 82. The positioning post 82 is provided with a second supporting hole 81. The diameter of the second supporting hole 81 is substantially the same as the outer diameter of the second end portion 61a of the rotating shaft 61 of the developing member 6. The outer diameter of the positioning post 82 is matched with the inner diameter of the second mounting hole 33. When the mounting plate 8 is mounted on the second housing 31 in the reverse direction of the X direction, the positioning post 82 is inserted in the reverse direction of the X direction to the second. In the mounting hole 33, the second support hole 81 of the positioning post 82 is fitted over the rotating shaft 61 of the developing member 6. On the second end portion 61a, the second end portion 61a of the rotating shaft 61 of the developing member is rotatably supported on the mounting plate 8, and then the mounting plate 8 and the second housing 31 are screwed, pasted, welded, or the like. The second end portion 61a of the rotating shaft 6 of the developing member is fixedly connected.
本实施例中,优选地,通过将定位柱82的横截面的形状设置成与第二安装孔33的形状基本相同,当将安装板8安装到第二壳体31上后,通过定位柱82与第二安装孔33的配合,使安装板8对使显影元件的旋转轴的第二端部61a的定位更加稳定。In the present embodiment, preferably, by arranging the shape of the cross section of the positioning post 82 to be substantially the same as the shape of the second mounting hole 33, after the mounting plate 8 is mounted on the second housing 31, the positioning post 82 is passed. The engagement with the second mounting hole 33 makes the mounting plate 8 more stable to the positioning of the second end portion 61a of the rotating shaft of the developing member.
当将安装板8安装完成后,显影元件6的旋转轴61的第二端部61a穿过第二安装孔33,并伸出到安装板8沿X方向的一侧与第一传动齿轮11连接。如图2和图4所示,第二端部61a的横截面设置成非圆形,第一传动齿轮11设置有与第二端部61a的横截面形状基本相同的通孔11a。第一传动齿轮11沿X方向的反向安装到第二端部61a上,通过将第一传动齿轮11上设置的非圆横截面形状的通孔11a套在非圆横截面形状的第二端部61a上,从而使显影元件6与第一传动齿轮11联动。When the mounting plate 8 is mounted, the second end portion 61a of the rotating shaft 61 of the developing member 6 passes through the second mounting hole 33 and protrudes to the side of the mounting plate 8 in the X direction to be coupled to the first transmission gear 11. .

The portion 61a is such that the developing member 6 is interlocked with the first transmission gear 11.
通过通孔11a与第二端部61a的配合,使显影元件6会随着第一传动齿轮11的转动而转动,但是,第一传动齿轮11与显影元件6之间并没有沿显影元件的轴向方向的作用力,因此,安装在第二端部61a上的第一传动齿轮11很容易沿X方向移动而与显影元件6脱离连接。为了防止出现这种情况,本实施例中,在第二传动齿轮12上设置了一个挡板121。By the cooperation of the through hole 11a and the second end portion 61a, the developing member 6 is rotated in accordance with the rotation of the first transmission gear 11, but there is no axis along the developing member between the first transmission gear 11 and the developing member 6. The force in the direction, therefore, the first transmission gear 11 mounted on the second end portion 61a is easily moved in the X direction to be disconnected from the developing member 6. In order to prevent this from occurring, in the present embodiment, a baffle 121 is provided on the second transmission gear 12.
如图4所示,第二传动齿轮12设置在安装板8上,并与第一传动齿轮11啮合。第二传动齿轮12通过螺钉、卡扣等方式与安装板8可旋转连接,而不会从安装板8上脱离。挡板121设置在第二传动齿轮12沿X方向的一侧,当将第二传动齿轮12安装到安装板8上之后,第二传动齿轮12与第一传动齿轮11啮合,且挡板121位于第一传动齿轮11沿X方向的一侧,并且,在X方向上,挡板121与第一传动齿轮11d的轴向外侧部分重叠,使挡板121能够阻止第一传动齿轮11沿X方向移动。为了满足上述要求,挡板的尺寸应满足:第二传动齿轮12的节圆面积在挡板121的范围内。本实施例中,优选地,挡板121为圆形,且挡板121的直径大于第二传动齿轮12的齿顶圆直径。As shown in FIG. 4, the second transmission gear 12 is disposed on the mounting plate 8 and meshes with the first transmission gear 11. The second transmission gear 12 is rotatably coupled to the mounting plate 8 by screws, snaps, or the like without being detached from the mounting plate 8. The baffle 121 is disposed on one side of the second transfer gear 12 in the X direction. After the second transfer gear 12 is mounted on the mounting plate 8, the second transfer gear 12 meshes with the first transfer gear 11, and the baffle 121 is located The first transmission gear 11 is on one side in the X direction, and in the X direction, the flap 121 overlaps with the axially outer portion of the first transmission gear 11d, so that the flap 121 can prevent the first transmission gear 11 from moving in the X direction. . In order to satisfy the above requirements, the size of the baffle should be such that the pitch area of the second transfer gear 12 is within the range of the baffle 121. In this embodiment, preferably, the baffle 121 is circular, and the diameter of the baffle 121 is larger than the diameter of the addendum circle of the second transfer gear 12.

The opposite side of the first casing 21 in the direction (Y direction) in which the developing cartridge 3 is attached to the drum assembly 2 is the abutting portion 22. After the developing cartridge 3 is mounted on the drum assembly 2 in the Y direction, the drum assembly 2 supports and positions the developing cartridge 3 through the first side panel 23, the second side panel 24, and the abutting portion 22, so that the developing cartridge 3 is developed. The element 6 is held in a predetermined position with the photosensitive element 25 of the drum assembly 2.
参照图1、图4和7所示,显影盒3的第二壳体31沿处理盒的长度方向(X方向)两端设置有导向轴41,并且在显影盒3上与抵接部22相对的面上设置有支撑凸起42。支撑凸起42的数量可以是一个或多个。本实施例中,支撑凸起42的数量为两个,分别设置在显影盒3沿X方向的两端。与显影盒3的导向轴41相对的,鼓组件2的第一侧板23和第二侧板24上还设置有凹口26。凹口26为设置有缺口的圆孔,圆孔的直径与导向轴41的直径基本相同,缺口的距离大于导向轴41的直径,其尺寸满足:导向轴41沿径向方向穿过该缺口。当将显影盒3安装到鼓组件2上时,显影盒3的第二壳体31两端的导向轴41进入到凹口26内,并且第二壳体31上的支撑凸起42与抵接部22抵接,显影盒3与鼓组件2处于预定位置。Referring to FIGS. 1, 4 and 7, the second casing 31 of the developing cartridge 3 is provided with guide shafts 41 at both ends in the longitudinal direction (X direction) of the process cartridge, and is opposed to the abutting portion 22 on the developing cartridge 3. A support protrusion 42 is provided on the face. The number of support protrusions 42 may be one or more.

The direction of the rotating shaft 71 is parallel to the direction of the rotating shaft 61 of the developing element, and the pushed portion 711 and the holding portion 715 are both connected to the rotating shaft 71 and protrude in a direction perpendicular to the axial direction of the rotating shaft 71. The extending direction of the pushed portion 711 and the extending direction of the holding portion 715 are set at a set angle according to the structure of the second casing 31, and the grip portion 715 is provided with a claw 716 at the end portion in the extending direction. In specific implementation, the rotation of the rotating shaft 71 can be realized by the elastic member 72 sleeved on the rotating shaft 71. The elastic member 72 is preferably a torsion spring. The mounting hole includes a third mounting hole 73 and a fourth mounting hole 74 distributed along the X-square direction. In specific implementation, the third mounting hole 73 may be a circular hole provided with a notch, and the diameter of the circular hole and the diameter of one end 713 of the rotating shaft Basically the same, and the distance of the notch is smaller than the outer diameter of one end 713 of the rotating shaft. The fourth mounting hole 74 is a circular hole having a diameter substantially the same as the outer diameter of the other end 714 of the rotating shaft. When the rotary holding member 70 is mounted on the second housing 31, the axial direction of the rotating shaft 71 holding the rotary holding member 70 is at an angle with the X direction, and the other end 714 of the rotating shaft of the rotating holding member 70 is first rotated. Through the fourth mounting hole, then, one end 713 of the rotating shaft of the rotating holding member 70 passes through the notch of the third mounting hole 73 in the radial direction of the rotating shaft 71, so that the rotating holding member 70 is rotatably supported in the developing On the second housing 31 of the cartridge 3. The torsion spring applies a rotational force to the rotary holder 70 so that the torsion spring can push the rotary holder 70 to rotate about the rotary shaft 71 when the developing cartridge 3 is not mounted to the drum assembly 2. When the rotary latch 70 is installed, the torsion spring is sleeved on the rotating shaft 71. The first end of the torsion spring abuts against the second housing 31, and the second end of the torsion spring abuts the rotating holder 70, thereby The rotary holder 70 applies a rotational force.
优选地,在旋转卡持件70的卡持部715上还设有朝向卡持部715的一侧延伸的凸条717,扭簧的第二端抵接在凸条717上,防止旋转卡持件70在旋转的过程中,扭簧的第二端与旋转卡持件70脱离。Preferably, a rib 717 extending toward a side of the latching portion 715 is further disposed on the latching portion 715 of the rotating latch 70, and the second end of the torsion spring abuts on the rib 717 to prevent the rotation of the latching portion During the rotation of the member 70, the second end of the torsion spring is disengaged from the rotary catch 70.
参照图14所示,扭簧对旋转卡持件70施加的旋转力使旋转卡持件70绕着转轴沿顺时针方向转动,直到旋转卡持件70的受推部711与第二壳体31抵接,旋转卡持件70的旋转停止。在将显影盒3安装到鼓组件2上的过程中,卡持部715的卡爪716会与抵接部22沿Z方向一侧的斜面接触,并且,卡爪716受到斜面的挤压,从而带动旋转卡持件70绕着转轴71沿逆时针方向转动,直到卡爪716移动到抵接部22沿Z方向的下方, 抵接部22对卡爪716的作用力消失,旋转卡持件70在扭簧的作用下沿顺时针方向旋转,使卡爪716勾在抵接部22上,从而防止显影盒3相对鼓组件2绕着导向轴沿顺时针方向转动,显影盒3相对鼓组件2被定位。从而使显影盒3与鼓组件2之间的位置固定,防止在从电子成像装置中取出处理盒的过程中,或将处理盒安装到电子成像装置的过程中,显影盒3与鼓组件2脱离。Referring to FIG. 14, the rotational force applied by the torsion spring to the rotary catching member 70 causes the rotary catching member 70 to rotate in the clockwise direction about the rotating shaft until the pushed portion 711 of the rotating catching member 70 and the second housing 31 are rotated. Upon abutment, the rotation of the rotation catch 70 is stopped. In the process of mounting the developing cartridge 3 to the drum assembly 2, the claw 716 of the catching portion 715 comes into contact with the inclined surface of the abutting portion 22 on one side in the Z direction, and the claw 716 is pressed by the inclined surface, thereby The rotation holding member 70 is rotated in the counterclockwise direction about the rotating shaft 71 until the claw 716 moves to the lower side of the abutting portion 22 in the Z direction. The force of the abutting portion 22 on the claw 716 disappears, and the rotary catching member 70 rotates in the clockwise direction under the action of the torsion spring, so that the claw 716 is hooked on the abutting portion 22, thereby preventing the developing cartridge 3 from opposing the drum assembly. 2 is rotated in the clockwise direction about the guide shaft, and the developing cartridge 3 is positioned relative to the drum assembly 2. Thereby, the position between the developing cartridge 3 and the drum assembly 2 is fixed, preventing the developing cartridge 3 from being separated from the drum assembly 2 during the process of taking out the process cartridge from the electronic image forming apparatus, or during the process of mounting the process cartridge to the electronic image forming apparatus. .
本实施例中,卡持部715和卡爪716的数量可以为一个或多个,其数量可以根据具体情况设置。In this embodiment, the number of the holding portions 715 and the claws 716 may be one or more, and the number thereof may be set according to a specific situation.
当需要将显影盒3从鼓组件2上取下时,如图14所示,使用者对受推部711施加一个作用力,该作用力对转轴71的矩的方向为逆时针方向,从而使旋转卡持件70相对转轴71沿逆时针方向转动,卡爪716与抵接部22脱离,从而使显影盒3能够相对鼓组件2转动,便于将显影盒3从鼓组件2上取下。When it is necessary to remove the developing cartridge 3 from the drum assembly 2, as shown in Fig. 14, the user applies a force to the pushed portion 711 which is counterclockwise to the direction of the moment of the rotating shaft 71, thereby The rotary catching member 70 is rotated in the counterclockwise direction with respect to the rotary shaft 71, and the claw 716 is disengaged from the abutting portion 22, thereby enabling the developing cartridge 3 to be rotated relative to the drum assembly 2, facilitating removal of the developing cartridge 3 from the drum assembly 2.
