Technical Field

[0001] This utility model relates to the field of electronic imaging equipment, and more particularly to a processing box that can be detachably installed in electronic imaging equipment. Background Technology

[0002] The processing box is detachably installed on the imaging device. Generally, the processing box has a driving force receiver for receiving driving force from the imaging device. Before installation, the axis of the driving force receiver of the existing processing box is not parallel to the extension direction of the processing box. After the processing box is installed in the predetermined position of the imaging device, the axis of the driving force receiver is parallel to the extension direction of the processing box. However, the structure of the driving force receiver of this type is complex, the installation requires high precision, and the processing box with this driving force receiver needs to be matched with the corresponding model of imaging device, which is not very versatile. Utility Model Content

[0003] This utility model provides a processing box to solve the above-mentioned technical problems. The specific solution is as follows:

[0004] A processing cartridge, detachably mounted to an imaging device having a drive force output element, the processing cartridge comprising: a developing housing for containing developer; a developing roller rotatably disposed in the developing housing for carrying developer, having a first rotation axis extending in a longitudinal direction; a drive force receiver for receiving drive force from the drive force output element and driving the developing roller to rotate, the drive force receiver having a second rotation axis extending in a longitudinal direction and being movable in a longitudinal direction, one end of the drive force receiver being a driving end, and the other end opposite the driving end in the longitudinal direction being a non-driving end; an adjusting member for engaging with the drive force receiver to keep the second rotation axis parallel to the longitudinal direction; and a first elastic member for resetting the drive force receiver in the longitudinal direction, wherein the adjusting member is further away from the developing housing than the first elastic member in the longitudinal direction.

[0005] The adjusting member includes a first body having a first part and a second part, the first part having a first notch and the second part having a second notch, and when the first part and the second part are closed together, the first notch and the second notch form a second exposure hole for allowing the driving force receiving member to pass through.

[0006] When viewed along the radial direction of the driving force receiver, the adjustment member overlaps with the driving force receiver.

[0007] The driving force receiving member includes a main body, a connecting part, and a force receiving part. The connecting part connects the main body and the force receiving part in the left-right direction. The force receiving part is further away from the developing housing than the main body. The force receiving part is used to receive driving force from the driving force output member. The connecting part is used to movably engage with the second exposure hole.

[0008] The driving force receiving component further includes a first joint, a second joint, and a third joint disposed in the main body. In the longitudinal direction, the first joint is closer to the non-driving end than the second joint, and the first joint is farther away from the non-driving end than the third joint.

[0009] The processing box further includes a driving force transmission assembly having at least a first transmission member, the first transmission member having a first coupled portion for abutting against the first coupled portion to receive driving force from the driving force receiving member; the adjusting member further includes a second coupled portion disposed on the first body for interacting with the second coupled portion; the third coupled portion is for contacting one end of the first elastic member.

[0010] Along the radial direction of the driving force receiver, the dimensions of the main body and the force-receiving part are larger than the dimensions of the second exposure hole.

[0013] Figure 2 This is an exploded view of some components of the processing box involved in this utility model.

[0014] Figure 3 This is a schematic diagram showing the combination of the driving force receiving component and the adjusting component in the processing box involved in this utility model. Detailed Implementation

[0015] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0016] The processing cartridge C includes at least a developing cartridge 100, which is detachably mounted into an imaging device equipped with a drive force output element. For accuracy and ease of understanding, the developing cartridge 100 is defined as having a front, rear, left, right, top, and bottom as shown in the figure. Specifically, the front-back, left-right, and top-bottom directions intersect each other. Preferably, the front-back, left-right, and top-bottom directions are perpendicular to each other. The left-right direction is the length direction / longitudinal direction / axial direction of the developing cartridge 100, and the developing cartridge 100 extends along the left-right direction.

[0017] like Figure 1 and Figure 2 As shown, the developing cartridge 100 includes a developing housing 1, a developing roller 21 rotatably disposed on the developing housing 1, and a driving force receiving and transmitting assembly 3. The developing housing 1 is used to contain developer, and the developing roller 21 is used to carry developer and supply it to a photosensitive drum (not shown) outside the developing cartridge 100. The driving force receiving and transmitting assembly 3 is used to receive driving force from the imaging device and transmit the driving force to the developing roller 21 to drive the developing roller 21 to rotate about a first rotation axis L21 parallel to the left and right direction. Further, the driving force receiving and transmitting assembly 3 includes a driving force receiving member 31 and a driving force transmitting assembly 32. The driving force receiving member 31 is used to receive the driving force output by the driving force output member and rotate about a second rotation axis L31 parallel to the left and right direction. The driving force transmitting assembly 32 is used to directly or indirectly transmit the driving force received by the driving force receiving member 31 to the developing roller 21 to drive the developing roller 21 to rotate.

[0018] In this embodiment, the driving force receiver 31 is located on the right side of the figure. The end where the driving force receiver 31 is located is defined as the driving end, and the end opposite to the driving end along the left-right direction is the non-driving end / left side.

[0019] like Figure 2 and Figure 3 As shown, the driving force receiving member 31 can move relative to the developing housing 1 in the left-right direction. The driving force receiving and transmitting assembly 3 also includes an adjusting member 33 and a first elastic member 34. In the left-right direction, the adjusting member 33 is further away from the developing housing 1 than the first elastic member 34. The adjusting member 33 is used to engage with the driving force receiving member 31 so that the second rotation axis L31 of the driving force receiving member 31 remains parallel to the left-right direction and can move in the left-right direction. The first elastic member 34 is used to enable the driving force receiving member 31 to move to the right in the left-right direction to reset.

[0020] In some embodiments, the first elastic member 34 is configured as a compression spring.

[0021] Furthermore, the developing cartridge 100 also includes a first cover 13 connected to the developing housing 1. Along the left-right direction, the first cover 13 is disposed at the driving end of the developing housing 1. The first cover 13 is used to protect the driving end of the developing housing 1 to prevent damage to the various components disposed at the driving end. The first cover 13 includes a first cover body 130 and a first exposure hole 131 disposed in the first cover body 130. The driving force receiving member 31 is exposed through the first exposure hole 131 so as to be able to receive driving force from the driving force output member.

[0022] Furthermore, along the left-right direction, the developing housing 1, the first elastic member 34, and the driving force receiver 31 are arranged sequentially from left to right. When viewed in the radial direction, the adjusting member 33 overlaps with the driving force receiver 31, and the driving force receiver 31 is movable relative to the adjusting member 33. For example, the driving force receiver 31 is rotatable relative to the adjusting member 33 and can move in the left-right direction relative to the adjusting member 33. During the process of installing the developing cartridge 100 into the imaging device, when the driving force receiver 31 interferes with other components in the imaging device, the driving force receiver 31 can move in the left-right direction toward the non-driving end, thereby enabling the developing cartridge 100 to be installed smoothly.

[0023] Furthermore, the driving force receiving member 31 includes a main body 311, a connecting part 312, and a force receiving part 313. The connecting part 312 connects the main body 311 and the force receiving part 313. In the left-right direction, the force receiving part 313, the connecting part 312, and the main body 311 are connected sequentially from right to left. That is, in the left-right direction, the force receiving part 313 is further away from the developing housing 1 than the main body 311. The driving force receiving member 31 is formed integrally or separately. Preferably, the driving force receiving member 31 is formed integrally to better transmit the driving force. Furthermore, the force receiving part 313 is used to receive the driving force from the driving force output member, and the connecting part 312 is used to cooperate with the adjustment member 33.

[0024] Furthermore, the driving force receiving member 31 also includes a first connecting portion 3141, a second connecting portion 3142, and a third connecting portion 3143 disposed on the main body portion 311. In the left-right direction, the first connecting portion 3141 is closer to the non-driving end than the second connecting portion 3142, and the first connecting portion 3141 is farther from the non-driving end than the third connecting portion 3143. The first connecting portion 3141 is used to cooperate with a part of the driving force transmission assembly 32. For example, the driving force transmission assembly 32 includes at least a first transmitting member 321, which has a first connected portion 3211. The first connected portion 3211 abuts against the first connecting portion 3141 to receive driving force from the driving force receiving member 31. The second connecting portion 3142 is used to cooperate with a part of the adjusting member 33. For example, the adjusting member 33 also includes a second connected portion 333 disposed on the first main body 331. The second connected portion 333 interacts with the second connecting portion 3142. Specifically… During the installation of the developing cartridge 100 into the imaging device, when the driving force receiver 31 is touched by other components in the imaging device and moves in the left-right direction toward the non-driving end, the second coupling portion 333 is used to abut against the second coupling portion 3142 to limit the range of movement of the driving force receiver 31 in the left-right direction toward the non-driving end; the third coupling portion 3143 is used to contact one end of the first elastic member 34. For example, during the installation of the developing cartridge 100 into the imaging device, when the driving force receiver 31 is touched by other components in the imaging device and moves in the left-right direction toward the non-driving end, the third coupling portion 3143 abuts against and presses the first elastic member 34 to produce elastic deformation. When the developing cartridge 100 is installed in the predetermined position, under the elastic force of the first elastic member 34, the driving force receiver 31 is forced to move in the left-right direction away from the non-driving end so as to receive driving force from the driving force output member.

[0025] In some embodiments, the driving force receiver 31 / connecting part 312 and the adjusting member 33 are fitted with a shaft hole. Along the radial direction of the driving force receiver 31, the size of the main body part 311 and the size of the force-receiving part 313 are larger than the size of the second exposure hole 332 to prevent the adjusting member 33 from disengaging from the driving force receiver 31.

[0026] In some embodiments, the adjusting member 33 is disposed on the first cover 13, for example, by snap-fit ​​or by screw fixing.

[0027] In some embodiments, the adjusting member 33 may also be disposed on the developing housing 1 or other components, as long as the driving force receiving member 31 can be moved in the left and right direction.

[0028] In some embodiments, the adjusting member 33 is preferably detachably mounted to the first cover 13 or the developing housing 1 or other components by means of screws.

[0029] Furthermore, the adjusting member 33 includes a first body 331 and a second exposure hole 332 disposed in the first body 331, the second exposure hole 332 being used to allow the driving force receiving member 31 to pass through.

[0030] In some embodiments, the first body 331 includes a first part 331a and a second part 331b, which are formed separately. The first part 331a has a first notch 3321 and the second part 331b has a second notch 3322. After the first part 331a and the second part 331b are enclosed, the first notch 3321 and the second notch 3322 form a second exposure hole 332. That is, the second exposure hole 332 is formed between the first part 331a and the second part 331b. This arrangement can facilitate the installation of the adjustment component 33.

[0031] Beneficial effects: The adjusting member 33 is detachably configured. When it is necessary to use other types of imaging equipment, by installing the adjusting member 33, the axis of the driving force receiver 31 is kept parallel to the left and right direction before the processing cartridge C / developing cartridge 100 is installed in the imaging equipment, and the driving force receiver 31 can move in the left and right direction. In addition, by setting the first elastic member 34, the driving force receiver 31 can be reset away from the non-driving end, thereby enabling it to be used with other types of imaging equipment, which greatly improves the versatility of the processing cartridge C / developing cartridge 100. When it is not necessary to use other types of imaging equipment, the adjusting member 33 can be removed. In this way, before the processing cartridge C / developing cartridge 100 is installed in the imaging equipment, it is not necessary to keep the axis of the driving force receiver 31 parallel to the left and right direction. The first elastic member 34 can be removed or retained. That is, the first elastic member 34 can be retained. When the first elastic member 34 is retained, the installation / removal of the processing cartridge C / developing cartridge 100 can be made smoother.
