Among them, the rotating element can be connected to a power receiving component and receive a driving force from the power receiving component. The power receiving component is usually arranged on a side wall of the processing box, and is used to receive a driving force from the main body of the image forming device.

[0032] Reference Figure 1 and Figure 2 As shown, Figure 1 A schematic diagram of the structure of an image forming device provided in an embodiment of the present application is shown in FIG. Figure 2 The schematic diagram of the structure of a group of four process cartridges of different colors provided in an embodiment of the present application. The image forming device comprises an image forming device body 200 and a process cartridge 100, and the process cartridge 100 is detachably mounted in the image forming device body 200.

[0033] Specifically, the image forming apparatus further comprises a process cartridge mounting frame 201, a first pushing portion 202 and a second pushing portion 203. The process cartridge mounting frame 201 is slidably connected to the image forming apparatus main body 200 and is used to mount the process cartridge 100. The first pushing portion 202 and the second pushing portion 203 are respectively arranged on one side of the image forming apparatus main body 200. When mounting the process cartridge 100, the process cartridge mounting frame 201 is pulled out from the image forming apparatus main body 200, the process cartridge 100 is mounted in the process cartridge mounting frame 201, and then the process cartridge mounting frame 201 is moved along the mounting direction ( Figure 1 When the process cartridge 100 is installed in place, the door cover of the image forming apparatus is closed, and the first pusher 202 rotates and pushes the components on the process cartridge 100 along the installation direction of the process cartridge 100; when the process cartridge 100 needs to be separated from the developing roller and the photosensitive drum, the second pusher 203 pushes the components on the process cartridge 100 in the opposite direction of the installation direction of the process cartridge 100.

[0034] Reference Figure 3 As shown, Figure 3 A cross-sectional view of a processing box provided in an embodiment of the present application. The processing box 100 includes a powder cartridge 1, a waste cartridge 2, and an elastic separation component 3. The powder cartridge 1 and the waste cartridge 2 are movably connected, and the powder cartridge 1 includes a developing roller 12, and the waste cartridge 2 includes a photosensitive drum 22. The elastic separation component 3 is used to generate displacement when receiving a driving force applied by the second pushing portion 203, and then the powder cartridge 1 and / or the waste cartridge 2 are pushed to move or rotate through the elastic separation component 3, so that the developing roller 12 is separated from the photosensitive drum 22.

[0035] Specifically, when the second pushing portion 203 applies a driving force along the first direction to the elastic separation component 3, the elastic separation component 3 is displaced to drive the powder tube 1 and the waste tube 2 to move in opposite directions, so that the developing roller 12 is separated from the photosensitive drum 22; when the second pushing portion 203 releases the driving force applied to the elastic separation component 3, the elastic separation component 3 returns to its initial position (the position where the elastic separation component 3 is located when no force is applied), so that the developing roller 12 is in contact with the photosensitive drum 22, wherein the first direction is the direction opposite to the installation direction of the processing box 100.

[0036] Continue to refer to Figure 3As shown, the processing box 100 also includes an elastic component. The powder cartridge 1 includes a powder cartridge body 11 and a developing roller 12, and the powder cartridge body 11 has a first accommodating chamber 111, and the first accommodating chamber 111 is used to accommodate printing powder. The waste cartridge 2 includes a waste cartridge body 21 and a photosensitive drum 22, and the waste cartridge body 21 has a second accommodating chamber 211, and the second accommodating chamber 211 is used to accommodate used printing powder. During assembly, the developing roller 12 is connected to the powder cartridge body 11, and the photosensitive drum 22 is connected to the waste cartridge body 21. The waste cartridge body 21 is connected to the powder cartridge body 11 through an elastic component, and when the processing box 100 is in an imaging working state, the developing roller 12 is in contact with the photosensitive drum 22.

[0037] Specifically, the powder cartridge 1 also includes a connecting member 13, which is connected to one end of the powder cartridge body 11 away from the developing roller 12. The elastic separation assembly 3 includes a driving member 31, a first elastic member 32, a separating member 33 and a second elastic member (not shown in the figure). The separating member 33 is arranged between the powder cartridge body 11 and the waste cartridge body 21, and is connected to the body of the processing box through the second elastic member. The separating member 33 is used to be inserted between the developing roller 12 and the photosensitive drum 22, so that the developing roller 12 and the photosensitive drum 22 move in opposite directions, thereby separating the developing roller 12 and the photosensitive drum 22. One end of the driving member 31 is connected to the connecting member 13 through the first elastic member 32, and the other end of the driving member 31 is used to push the separating member 33 so that the separating member 33 moves along the second direction. Wherein, the first elastic member 32 is a tension spring.

[0038] When the second pushing portion 203 applies a driving force to the driving member 31 along the first direction, the driving member 31 moves along the first direction and pushes the separating member 33 to move along the second direction, so that the separating member 33 is inserted between the developing roller 12 and the photosensitive drum 22, so that the developing roller 12 is separated from the photosensitive drum 22. When the second pushing portion 203 releases the driving force applied to the driving member 31, the driving member 31 moves toward the direction close to the connecting member 13 under the elastic force of the first elastic member 32, that is, the driving member 31 moves toward the direction away from the separating member 33, so that the driving member 31 is separated from the separating member 33. At this time, the separating member 33 moves toward the direction away from the developing roller 12 and the photosensitive drum 22 under the action of the second elastic member, so that the developing roller 12 and the photosensitive drum 22 are in contact under the action of the elastic member. The second direction is perpendicular to the first direction.

[0039] It is understandable that in other embodiments, the separator 33 may be designed to only push the photosensitive drum 22 away from the developing roller 12 after movement, or the separator 33 may only push the developing roller 12 away from the photosensitive drum 22 after movement. In this way, the separation of the developing roller 12 and the photosensitive drum 22 can also be achieved.

[0040] In this embodiment, the end of the driving member 31 away from the first elastic member 32 has a first inclined surface 311, and the end of the separation member 33 close to the driving member 31 has a second inclined surface 331. The first inclined surface 311 and the second inclined surface 331 are arranged correspondingly to achieve the change of the movement direction. It can be understood that in other embodiments, the change of the movement direction can also be achieved by a gear rack or a bevel gear.

[0041] In order to prevent the separator 33 from damaging the developing roller 12 and the photosensitive drum 22 when being inserted between the developing roller 12 and the photosensitive drum 22, one end of the separator 33 used for being inserted between the developing roller 12 and the photosensitive drum 22 is made of a flexible material, and the end is configured as a pointed structure, thereby making the separation process of the developing roller 12 and the photosensitive drum 22 smoother.

[0042] Further, the powder cartridge 1 further includes a first limiting member 14 and a second limiting member 15, and the first limiting member 14 and the second limiting member 15 are spaced apart and connected to one end of the powder cartridge body 11 away from the developing roller 12. The driving member 31 includes a connecting portion 312, a first limiting portion 313 and a second limiting portion 314, and the two ends of the connecting portion 312 are respectively connected to the first limiting portion 313 and the second limiting portion 314. The first limiting portion 313 is connected to the connecting member 13 via the first elastic member 32, and the first limiting portion 313 and the first limiting member 14 can cooperate to limit. The second limiting portion 314 can cooperate to limit with the second limiting member 15, and the first inclined surface 311 is provided on the second limiting portion 314.

[0043] Reference Figure 4 As shown, Figure 4 A cross-sectional view of a processing box provided for another embodiment of the present application. In this embodiment, the processing box 100 includes a powder barrel 1, a waste barrel 2, an elastic separation component 3 and an end cover 4. The powder barrel 1 and the waste barrel 2 are movably connected, and the end cover 4 is arranged at the outermost sides of the two ends of the length direction of the powder barrel 1 and the waste barrel 2. The setting of the end cover 4 can support the powder barrel 1 and the waste barrel 2, and at the same time protect the gear set and other parts of the processing box from detaching. The elastic separation component 3 is connected to the end cover 4. When the elastic separation component 3 is subjected to a driving force along the first direction, the elastic separation component 3 moves in the second direction to push the powder barrel 1 to rotate, so that the developing roller 12 is separated from the photosensitive drum 22. Among them, the first direction is the direction opposite to the installation direction of the processing box 100, and the second direction is the direction perpendicular to the first direction.

[0044] Specifically, the end cover 4 includes a cover body 41 and a connecting component 42, the cover body 41 has an installation cavity 411, the installation cavity 411 has an opening 412, and the connecting component 42 is connected to the inner wall of the installation cavity 411. The powder cartridge 1 includes a powder cartridge body 11 and a developing roller 12, the powder cartridge body 11 has a first accommodating cavity 111, and the first accommodating cavity 111 is used to accommodate printing powder. The waste cartridge 2 includes a waste cartridge body 21 and a photosensitive drum 22, the waste cartridge body 21 has a second accommodating cavity 211, and the second accommodating cavity 211 is used to accommodate used printing powder. During assembly, the developing roller 12 is connected to the powder cartridge body 11, the photosensitive drum 22 is connected to the waste cartridge body 21, and the powder cartridge body 11 and the waste cartridge body 21 are connected via the rotating shaft 5 and the elastic component, so that the powder cartridge 1 and the waste cartridge 2 can rotate relative to each other when subjected to force, and can return to their initial positions when not subjected to force, and the ends of the powder cartridge body 11 and the waste cartridge body 21 are located in the mounting cavity 411.

[0045] The elastic separation component 3 includes a driving member 31 and a first elastic member 32. The driving member 31 is arranged at the opening 412, and one end of the driving member 31 is connected to the connecting part 42 via the first elastic member 32. The other end of the driving member 31 passes through the installation cavity 411 in a natural state (i.e., in a state without force).

[0046] In this embodiment, the driving member 31 is connected to the end cover via the first elastic member 32. It can be understood that in other embodiments, the driving member 31 can also be connected to the body or other components of the processing box via the first elastic member 32.

[0047] Furthermore, the driving member 31 has a driving surface 315 and a pushing surface 316, which are diagonally arranged. The driving surface 315 is used to contact the second pushing portion 203 to receive the driving force applied by the second pushing portion 203, and the pushing surface 316 is used to contact the powder cartridge body 11 to push the powder cartridge 1 to rotate.

[0048] When the second pushing part 203 applies a certain driving force to the driving surface 315 of the driving member 31, the driving member 31 moves along the second direction. When the driving member 31 moves to the pushing position, the pushing surface 316 of the driving member 31 contacts the receiving surface 112 of the powder cartridge body 11. Due to the different slopes of the two, as the driving member 31 is pressed down, the pushing surface 316 can push the powder cartridge body 11 to rotate around the rotating shaft 5, thereby separating the developing roller 12 from the photosensitive drum 22. When the second pushing part 203 releases the driving force applied to the driving member 31, the driving member 31 moves in a direction away from the connecting member 42 under the elastic force of the first elastic member 32, so that the driving member 31 is separated from the powder cartridge 1 and returns to the initial position. At this time, the elastic member between the powder cartridge 1 and the waste cartridge 2 can pull the two back to the initial position, so that the developing roller 12 contacts the photosensitive drum 22.

[0049] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
