Description

Technical Field

[0001] This utility model relates to the technical field of printing equipment, and in particular to a processing box with movable electrodes. Background Technology

[0002] Processing cartridges are typically installed in printing equipment in a detachable manner. When the processing cartridge is installed, the energized components in the printing equipment come into contact with the electrodes of the processing cartridge and are energized, thereby supplying power to the developing roller and supply roller in the processing cartridge to complete the printing process. However, in common processing cartridges on the market, the electrodes are in contact with the energized components both when the printing equipment is in operation and when it is not in operation. Over time, the energized components of the printing equipment are prone to wear and deformation, resulting in unstable operation of the printing equipment. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a processing box with movable electrodes, which can prevent the energized parts in the printing equipment from contacting the electrodes when not in operation, and further avoid the wear and deformation of the energized parts in the printing equipment and the instability of operation caused by long-term contact, thereby improving the stability and reliability of printing work.

[0004] The technical solution adopted by this utility model is as follows: This utility model includes a processing cartridge body, a first conductive element, and a second conductive element. The processing cartridge body is provided with an end cap and a developing assembly. The first conductive element is movably connected to the end cap and can move relative to the processing cartridge body. The second conductive element is connected to the developing assembly. The first conductive element and the second conductive element abut against each other. When the first conductive element moves away from the processing cartridge body, it can be connected to the printing device, and when it moves towards the processing cartridge body, it separates from the printing device.

[0005] Furthermore, the first conductive element moves away from the processing box body when the second conductive element rotates for the first stroke, and moves closer to the processing box body when the second conductive element completes the first stroke and continues to rotate for the second stroke.

[0006] Furthermore, the first conductive element is provided with a plurality of first saw teeth, and the second conductive element is provided with a plurality of second saw teeth, wherein the plurality of first saw teeth can respectively engage with the plurality of second saw teeth.

[0007] Furthermore, the second conductive element is a ring-shaped component, and the second conductive element is sleeved on the developing assembly.

[0008] Furthermore, the end cap is provided with an elastic extension, and the first conductive element is connected to the elastic extension.

[0009] Furthermore, a first elastic component is provided between the elastic extension and the first conductive component, and a second elastic component is provided between the processing box body and the first conductive component. The first elastic component and the second elastic component are respectively provided on the outer side and the inner side of the first conductive component, and are respectively located at both ends of the first conductive component.

[0010] Furthermore, the end cap has an opening, and the elastic extension is located in the opening.

[0011] Furthermore, the elastic extension includes a first extension and a second extension. One end of the first extension is connected to the end cap, and the other end is connected to the second extension. The first conductive member is provided with a connecting hole, a connecting groove, and an electrical contact. The connecting hole and the connecting groove are in communication. The first extension is disposed in the connecting groove, and the second extension is disposed in the connecting hole. The first elastic member is connected to the inner side of the second extension and is located in the connecting hole. The electrical contact can be made conductive with the elastic member of the printing device when the first conductive member moves away from the processing cartridge body.

[0012] Furthermore, the developing assembly includes a developing roller and a developing roller shaft. The developing roller shaft is connected to the end of the developing roller and is connected to the second conductive element. The developing roller is rotatably connected to the processing cartridge body and is drivenly connected to the coupling.

[0013] Furthermore, the first journey is equal to the second journey.

[0014] The beneficial effects of this utility model are: Compared to the shortcomings of existing technologies, in this invention, when the processing cartridge is not working, the distance between the first conductive element and the second conductive element is minimal, and at this time, the first conductive element is separated from the printing device, meaning there is no electrical connection between them. When the processing cartridge is working, the first conductive element moves away from the processing cartridge body, gradually increasing the distance between the second conductive element and the first conductive element, eventually bringing the first conductive element into contact with the printing device and energizing it. When the first conductive element moves closer to the processing cartridge body, the distance between the second conductive element and the first conductive element gradually decreases, thus separating the first conductive element from the printing device. Therefore, this invention can prevent the energized components in the printing device from contacting the electrodes when not in operation, further preventing wear and deformation of the energized components in the printing device and instability caused by prolonged contact, thereby improving the stability and reliability of the printing process.

[0020] like Figures 1 to 3 As shown, in this embodiment, the present invention includes a processing cartridge body 1, a first conductive element 2, and a second conductive element 3. The processing cartridge body 1 is provided with an end cap 5 and a developing assembly 6. The first conductive element 2 is movably connected to the end cap 5 and can move relative to the processing cartridge body 1. The second conductive element 3 is connected to the developing assembly 6. The first conductive element 2 and the second conductive element 3 abut against each other. When the first conductive element 2 moves away from the processing cartridge body 1, it can be connected to the printing device 7, and when it moves towards the processing cartridge body 1, it separates from the printing device 7.

[0021] The movable electrode includes a first conductive element 2 and a second conductive element 3. The first conductive element 2 is movable relative to the processing cartridge body 1. When the first conductive element 2 moves away from the processing cartridge body 1, the distance between it and the second conductive element 3 gradually increases to achieve contact and conduction between the first conductive element 2 and the printing device 7. When the first conductive element 2 moves closer to the processing cartridge body 1, the distance between it and the second conductive element 3 gradually decreases to achieve separation between the first conductive element 2 and the printing device 7. Compared with the shortcomings of the prior art, in this utility model, when the processing box is not working, the distance between the first conductive element 2 and the second conductive element 3 is the smallest. At this time, the first conductive element 2 is separated from the printing device 7, that is, there is no electrical connection between the two. When the processing box is working, the first conductive element 2 moves away from the processing box body 1, so that the distance between the second conductive element 3 and the first conductive element 2 gradually increases, and the first conductive element 2 eventually contacts the printing device 7 and becomes energized. When the first conductive element 2 moves closer to the processing box body 1, the distance between the second conductive element 3 and the first conductive element 2 gradually decreases, so as to separate the first conductive element 2 from the printing device 7. Therefore, this utility model can avoid the contact between the energized parts in the printing device and the electrodes when it is not working, and further avoid the wear and deformation of the energized parts in the printing device and the instability of operation caused by long-term contact, thus improving the stability and reliability of printing work.

[0022] In some embodiments, the first conductive element 2 moves away from the processing cartridge body 1 when the second conductive element 3 rotates for a first stroke, and moves closer to the processing cartridge body 1 when the second conductive element 3 completes its first stroke and continues to rotate for a second stroke; the first stroke and the second stroke are equal. Specifically, when the processing cartridge is not working, the distance between the first conductive element 2 and the second conductive element 3 is minimal, and at this time the first conductive element 2 is separated from the printing device 7, that is, there is no electrical connection between them; when the processing cartridge is working, the developing assembly 6 drives the second conductive element 3 to rotate for a first stroke, so that the distance between the second conductive element 3 and the first conductive element 2 gradually increases, so that the first conductive element 2 moves away from the processing cartridge body 1 and eventually contacts and energizes the printing device 7; when the second conductive element 3 completes its first stroke and continues to rotate for a second stroke, the distance between the second conductive element 3 and the first conductive element 2 gradually decreases, so that the first conductive element 2 moves closer to the processing cartridge body 1 and separates from the printing device 7; It should be noted that the units for the first and second strokes can be degrees or radians, and both strokes rotate in the same direction, with the first stroke being equal to the second stroke. like Figure 2 , Figures 4 to 5 As shown, in some embodiments, the first conductive element 2 is provided with a plurality of first saw teeth 8, and the second conductive element 3 is provided with a plurality of second saw teeth 9. The plurality of first saw teeth 8 can respectively mesh with the plurality of second saw teeth 9. The developing assembly 6 includes a developing roller 20 and a developing roller shaft 21. The developing roller shaft 21 is connected to the end of the developing roller 20 and is connected to the second conductive element 3. The developing roller 20 is rotatably connected to the processing cartridge body 1 and is drivenly connected to a coupling. The direction of the first saw teeth 8 is opposite to the direction of the second saw teeth 9. The developing roller 20 can abut against the photosensitive drum to transfer the developer. When the processing box is not working, the multiple first serrations 8 on the first conductive element 2 engage with the multiple second serrations 9 on the second conductive element 3, causing the electrical contact portion 18 of the first conductive element 2 to move closer to the processing box body 1. At this time, there is a certain gap between the electrical contact portion 18 of the first conductive element 2 and the elastic element 19 of the printing device 7. When the processing cartridge is working, it receives driving force through a coupling (not shown in the figure) to transmit power to the developing roller 20. Furthermore, the rotation of the developing roller 20 drives the second conductive element 3 to rotate, so that the end of the second sawtooth 9 on the second conductive element 3 contacts the end of the first sawtooth 8 on the first conductive element 2, so that the electrical contact portion 18 of the first conductive element 2 moves away from the processing cartridge body 1. At this time, the electrical contact portion 18 of the first conductive element 2 contacts and is energized with the elastic element 19 of the printing device 7. When the second conductive element 3 completes its first stroke, it changes from the state of meshing between the first saw tooth 8 and the second saw tooth 9 to the state of abutting between the end of the first saw tooth 8 and the end of the second saw tooth 9; when it continues to rotate for the second stroke, it changes from the state of abutting between the end of the first saw tooth 8 and the end of the second saw tooth 9 to the state of meshing between the first saw tooth 8 and the second saw tooth 9, that is, it returns to the initial state.

[0023] In some embodiments, the second conductive element 3 is an annular member, and the second conductive element 3 is sleeved on the developing assembly 6. Specifically, the second conductive element 3 is sleeved on the developing roller shaft 21.

[0024] like Figures 2 to 6 As shown, in some embodiments, the end cap 5 is provided with an elastic extension 10, and the first conductive member 2 is connected to the elastic extension 10; a first elastic component 11 is provided between the elastic extension 10 and the first conductive member 2, and a second elastic component 14 is provided between the processing box body 1 and the first conductive member 2. The first elastic component 11 and the second elastic component 14 are respectively provided on the outer and inner sides of the first conductive member 2, and are respectively located at both ends of the first conductive member 2; the end cap 5 has an opening 12, and the elastic extension 10 is located in the opening 12. The first elastic component 11 and the second elastic component 14 are both springs. Specifically, by connecting the first conductive member 2 to the elastic extension 10, the first conductive member 2 can move relative to the end cap 5 through the elasticity of the elastic extension 10; furthermore, the provision of the first elastic component 11 and the second elastic component 14 prevents the first conductive member 2 from making hard contact with the printing device 7, thereby achieving smooth conduction, and ensuring that the first conductive member 2 can move and reset accurately.

[0025] like Figures 3 to 6As shown, in some embodiments, the elastic extension 10 includes a first extension 13 and a second extension 15. One end of the first extension 13 is connected to the end cap 5, and the other end is connected to the second extension 15. The first conductive member 2 is provided with a connecting hole 16, a connecting groove 17, and an electrical contact 18. The connecting hole 16 and the connecting groove 17 communicate with each other. The first extension 13 is disposed in the connecting groove 17, and the second extension 15 is disposed in the connecting hole 16. The first elastic member 11 is connected to the inner side of the second extension 15 and is located in the connecting hole 16. The electrical contact 18 can conduct electricity with the elastic member 19 of the printing device 7 when the first conductive member 2 moves away from the processing cartridge body 1. Specifically, the first extension 13 is disposed in the connecting groove 17, and the second extension 15 is disposed in the connecting hole 16 to fix the position of the first conductive member 2. Moreover, since the elastic extension 10 itself is elastic, it can undergo a certain deformation, allowing the first conductive member 2 to move relative to the end cap 5.

[0026] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
