Description

Technical Field

[0001] This invention relates to the field of electrophotographic imaging technology, and more specifically to a regeneration processing cartridge and a regeneration method for manufacturing the aforementioned regeneration processing cartridge. Background Technology

[0002] The regeneration process for existing processing boxes typically includes the following steps: The boxes that are damaged or have broken frames are scrapped and recycled, while those that are intact are put into the recycling process. Disassembly involves breaking down the processing box into the box body, various roller components (such as developing roller, photosensitive drum, powder feeding roller, charging roller, etc.), scraper, sealing sponge, gears, chips, etc., and disassembling the developing frame and drum frame inside the box body. Cleaning involves removing toner and dust from the disassembled developing frame, drum frame, various rollers, scrapers, gears, chips, etc. Component inspection and replacement, including replacing various rollers and gears that have reached the wear threshold; Fill with matching toner, reassemble the developing frame, install a new seal at the toner hopper opening, and fill with special toner that matches the charge characteristics and melting point of the corresponding model through a specific toner filling port; Reassemble and reinstall the cleaned and replaced rollers, scrapers, gears, chips, etc., onto the box body; For finished product testing, the recycling box is printed with a standard test page.

[0003] Currently, installing a new seal on the toner cartridge opening typically requires disrupting the connection between the toner cartridge and the developing chamber on the developing frame. This can be done by cutting the weld lines or adhesive between the toner cartridge and the developing chamber, then bonding a new seal to the flat section at the toner cartridge opening, and finally reconnecting the toner cartridge and developing chamber using adhesive, welding, or other fixing components. However, this method of installing seals suffers from problems such as complex regeneration processes, high regeneration costs, poor structural stability, and a tendency to produce defects such as toner leakage. Summary of the Invention

[0004] The primary objective of this invention is to provide a recycling processing box that features a simple recycling process, low recycling cost, and the ability to maintain the stability of the original structure.

[0005] The second objective of this invention is to provide a method for regenerating a processing box that simplifies the regeneration process, reduces regeneration costs, and ensures the stability of the original structure.

[0006] To achieve the first objective of this invention, a regeneration processing cartridge is provided, comprising a cartridge body, which includes a toner cartridge, a developing cartridge, and a partition. The partition is disposed between the toner cartridge and the developing cartridge, and has a first opening communicating with the toner cartridge and the developing cartridge. The regeneration processing cartridge further includes a sealing element, comprising a sealing strip and a sealing film. The sealing strip is mounted on the partition and located within the developing cartridge, and has a second opening communicating with the first opening. The sealing film includes a sealing section and a free section. The sealing section is adhered to the sealing strip and covers the second opening. The free section extends from the second end of the sealing section towards the first end of the sealing section, such that both ends of the sealing film are on the same side. The sealing film is located on the side of the sealing strip facing the toner cartridge. The first end wall of the toner cartridge has a first through groove on the first end side of the sealing section, through which the free section extends to the outside of the toner cartridge. Alternatively, the sealing film is located on the side of the sealing strip facing the developing cartridge, and the second end wall of the developing cartridge has a second through groove on the first end side of the sealing section, through which the free section extends to the outside of the developing cartridge.

[0007] As can be seen from the above, when the regeneration cartridge does not have a toner feeding roller, its developing chamber space is relatively narrow, which cannot provide sufficient space for the sealing film to move, making it difficult to remove the sealing film. In this case, by placing the sealing film inside the toner chamber and providing a first through-slot on the first end wall of the toner chamber for the sealing film to move out, the removal operation is facilitated and highly reliable, and the installation of the seal during the regeneration process is also convenient. When the regeneration cartridge has a toner feeding roller, its developing chamber space is larger, providing sufficient space for the sealing film to move, so the sealing film can be placed inside the developing chamber; simultaneously, a second through-slot is provided on the second end wall of the developing chamber for the sealing film to move out. This invention provides regeneration cartridges with different structures, which can meet the regeneration requirements of different regeneration cartridge structures (with or without a toner feeding roller), and the regeneration process does not require cutting and reconnecting the toner chamber and developing chamber, simplifying the regeneration process, reducing regeneration costs, and ensuring the stability of the original structure.

[0008] A preferred embodiment is that when the first end wall is provided with a first through groove: the first end wall has a first receiving groove, the first through groove is located at the bottom of the first receiving groove, the first receiving groove is filled with a first sealing block, and the free section passes through the gap between the first sealing block and the first receiving groove.

[0009] As can be seen from the above, setting the first through groove at the bottom of the first receiving groove on the first end wall can provide installation space for the first sealing block; the first sealing block is filled in the first receiving groove to seal the first through groove and prevent toner from leaking out of the first through groove; the free section extends out of the powder hopper through the gap between the first sealing block and the first receiving groove, which not only ensures the smooth pulling of the sealing film, but also ensures the sealing reliability at the first through groove.

[0010] A further option is that the orthographic projection of the second opening on the partition is located within the orthographic projection of the first opening on the partition, and the sealing section is located within the first opening.

[0011] As can be seen from the above, by designing the orthographic projection of the second opening on the partition to be located within the orthographic projection of the first opening on the partition, and placing the sealing section within the first opening, the sealing film can be accurately installed in place, and the sealing film can be easily removed.

[0012] Another further embodiment is that the housing also includes a first end cap, which is installed at the first end of the toner and developing chambers. The first end cap covers the ends of the toner and developing chambers. The first end cap has a third through groove at the first through groove, and the free section extends to the outside of the first end cap through the third through groove.

[0013] As can be seen from the above, a third through groove is provided on the first end cap, allowing the free section of the sealing film to pass through and extend to the outside of the first end cap, thereby ensuring the smooth removal of the sealing film; at the same time, the first end cap covers the ends of the toner compartment and the developing compartment, and cooperates with the first sealing block, which can further improve the sealing reliability of the first through groove and effectively prevent toner from leaking from the first through groove.

[0014] Another preferred embodiment is that when the second end wall is provided with a second through groove: the second end wall has a second receiving groove, the second through groove is located at the bottom of the second receiving groove, the second receiving groove is filled with a second sealing block, and the free section passes through the gap between the second sealing block and the second receiving groove.

[0015] As can be seen from the above, setting the second through groove at the bottom of the second receiving groove on the second end wall can provide installation space for the second sealing block; the second sealing block is filled in the second receiving groove to seal the second through groove and prevent toner from leaking out of the second through groove; the free section extends out of the developing chamber through the gap between the second sealing block and the second receiving groove, which not only ensures the smooth pulling of the sealing film, but also ensures the sealing reliability at the second through groove.

[0016] A further option is that the orthographic projection of the first opening on the partition completely coincides with the orthographic projection of the second opening on the partition, or the orthographic projection of the first opening on the partition is located within the orthographic projection of the second opening on the partition.

[0017] As can be seen from the above, by designing the relative positions of the second opening and the first opening, it can be ensured that the toner in the toner hopper can smoothly enter the developing chamber, and toner can be prevented from accumulating at the junction of the partition and the sealing strip.

[0018] Another further embodiment is that the cartridge also includes a second end cap, which is installed at the first end of the toner cartridge and the developing cartridge. The second end cap covers the ends of the toner cartridge and the developing cartridge. The second end cap has a fourth through slot at the second through slot, and the free section extends to the outside of the second end cap through the fourth through slot.

[0019] As can be seen from the above, a fourth through groove is provided on the second end cover, through which the free section of the sealing film passes and extends to the outside of the second end cover, thereby ensuring the smooth removal of the sealing film; at the same time, the second end cover covers the ends of the toner compartment and the developing compartment, and cooperates with the second sealing block, which can further improve the sealing reliability at the second through groove and effectively prevent toner from leaking from the second through groove.

[0020] A further improvement is that the regeneration processing box also includes a powder feeding roller, which is located inside the developing chamber.

[0021] A further improvement is that the powder hopper is equipped with a powder filling port; the box also includes a sealing plug, which is detachably connected to the powder filling port and is used to seal the powder filling port.

[0022] As can be seen above, the toner hopper is equipped with a toner filling port. This allows users to easily replenish the toner hopper themselves when it is depleted, thereby extending the lifespan of the regeneration cartridge and reducing operating costs. It also facilitates the filling of the toner hopper during the regeneration process. The sealing plug is detachably connected to the toner filling port to seal it and prevent toner leakage.

[0023] To achieve the second objective of this invention, a method for regenerating a processing cartridge is provided. The processing cartridge includes a cartridge body, which includes a powder hopper, a developing hopper, and a partition. The partition is disposed between the powder hopper and the developing hopper. The partition has a first opening that connects the powder hopper and the developing hopper. The regeneration method includes a sealing element installation step. The sealing element includes a sealing strip and a sealing film. The sealing strip has a second opening. The sealing film includes a sealing section and a free section. The sealing element installation step includes: placing the sealing strip inside the developing hopper, fixing the first surface of the sealing strip to the partition, and connecting the second opening with the first opening; when the processing cartridge does not include a powder feeding roller, providing a first through groove on the first end wall of the powder hopper. The sealing section is bonded to the first surface, so that the sealing section covers the second opening. The first end of the sealing section and the first end wall are located on the same side of the powder hopper. The end of the free section passes through the first through groove from the inside of the powder hopper to the outside of the powder hopper, so that both ends of the sealing film are located on the same side of the powder hopper. When the processing box includes a powder feeding roller, a second through groove is provided on the second end wall of the developing chamber. The sealing section is bonded to the second surface of the sealing strip. The second surface is opposite to the first surface, so that the sealing section covers the second opening. The first end of the sealing section and the second end wall are located on the same side of the developing chamber. The end of the free section passes through the second through groove from the inside of the developing chamber to the outside of the developing chamber, so that both ends of the sealing film are located on the same side of the developing chamber. The powder feeding roller is placed inside the developing chamber.

[0024] As can be seen from the above, the regeneration method provided by this invention allows for flexible selection of whether the processing cartridge is equipped with a powder feeding roller, with the sealing film installed on either the powder hopper side or the developing hopper side, and corresponding slots formed on the end walls of the powder hopper or developing hopper for the sealing film to pass through. When regenerating the processing cartridge, there is no need to cut and reconnect the powder hopper and developing hopper, effectively simplifying the regeneration process, reducing regeneration costs, and ensuring the integrity and stability of the original cartridge structure.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0036] First embodiment of the regeneration treatment box Reference Figures 1 to 3The regeneration processing box 100 includes a box body 1, a sealing element 2, a developing roller 31, a sealing scraper 32, a powder discharge scraper 33, and a transmission wheel assembly 34.

[0037] Combination Figure 4 The cartridge 1 includes a toner hopper 11, a developing chamber 12, and a partition 13, with the partition 13 separating the toner hopper 11 and the developing chamber 12. The partition 13 has a first opening 131 that connects the toner hopper 11 and the developing chamber 12, allowing toner in the toner hopper 11 to enter the developing chamber 12 through the first opening 131. In this embodiment, the regeneration cartridge 100 does not have a toner feeding roller 35, therefore the internal space of its developing chamber 12 is relatively small.

[0038] The sealing element 2 includes a sealing strip 21 and a sealing membrane 22. The sealing strip 21 is preferably made of a sponge gasket and has a second opening 211. The sealing strip 21 is disposed inside the developing chamber 12 and is mounted on the partition 13, so that the second opening 211 and the first opening 131 are connected. The sealing strip 21 is preferably fixedly connected to the partition 13 by an adhesive to ensure a sealing effect.

[0039] The sealing film 22 includes a sealing section 221 and a free section 222. The sealing section 221 is adhered to the sealing strip 21 and covers the second opening 211 to seal the second opening 211, thereby preventing toner in the toner hopper 11 from entering the developing chamber 12 through the first opening 131 and the second opening 211, and avoiding toner leakage during transportation and storage before the regeneration processing cartridge 100 is opened.

[0040] Since the space of the developing chamber 12 is reduced in this embodiment, the sealing film 22 is placed inside the powder chamber 11, that is, in this embodiment: The sealing film 22 is located on the side of the sealing strip 21 facing the powder hopper 11, that is, the sealing section 221 is adhered to the side of the sealing strip 21 facing the powder hopper 11; combined Figure 5 The orthographic projection of the second opening 211 on the partition 13 lies within the orthographic projection of the first opening 131 on the partition 13, and the sealing section 221 is located within the first opening 131, so that the sealing section 221 of the sealing film 22 is completely contained within the space defined by the first opening 131. This design, on the one hand, allows the sealing film 22 to be quickly positioned during installation using the first opening 131, improving assembly efficiency, and preventing the sealing section 221 from adhering to the partition 13, thus ensuring the sealing effect of the sealing film 22; on the other hand, when removing the sealing film 22, the sealing section 221 can be smoothly pulled along the first opening 131 without being obstructed by the solid part of the partition 13 (since the sealing section 221 is only located within the first opening 131 and not between the sealing strip 21 and the partition 13), thereby effectively reducing the tearing resistance, ensuring that the sealing film 22 can be smoothly and completely removed, and guaranteeing the sealing effect of the sealing strip 21.

[0041] Combination Figure 6 The first end wall 11 of the powder hopper 11 is provided with a first through groove 1112 on the first end side of the sealing section 221. The free section 222 of the sealing membrane 22 extends from the second end of the sealing section 221 to the first end side of the sealing section 221 and extends out of the powder hopper 11 through the first through groove 1112, so that the two ends of the sealing membrane 22 are on the same side.

[0042] It is evident that for processing boxes without a powder feeding roller 35, the limited internal space of the developing chamber 12 makes it difficult for the sealing film 22 to be smoothly pulled out within the developing chamber 12. However, by arranging the sealing film 22 on one side of the powder chamber 11 with ample space, and using the first through groove 1112 on the first end wall 11 of the powder chamber 11 to guide the pulling end of the sealing film 22 to the outside of the powder chamber 11, the pulling stroke of the sealing film 22 is effectively extended. This also facilitates the positioning and installation of the sealing element 2 during regeneration assembly. Furthermore, the distribution of the sealing film 22 makes the removal of the sealing film 22 easier and smoother.

[0043] Furthermore, the first end wall 11 of the powder hopper 11 has a first receiving groove 1111, and a first through groove 1112 is located at the bottom of the first receiving groove 1111. The first receiving groove 1111 is filled with a first sealing block 1113, and a free section 222 passes through the gap between the first sealing block 1113 and the first receiving groove 1111. By opening the first through groove 1112 at the bottom of the first receiving groove 1111 on the first end wall 11, the first sealing block 1113 can be directly embedded in the first receiving groove 1111, thus fully utilizing the existing structural space of the first end wall 11 (i.e., the first receiving groove 1111), eliminating the need for additional fixing structures for the first sealing block 1113, and simplifying the regeneration process of the processing box. After the first sealing block 1113 is filled into the first receiving groove 1111, it can effectively seal the first through groove 1112, preventing the toner in the powder hopper 11 from leaking out through the first through groove 1112. Furthermore, by allowing the free section 222 of the sealing membrane 22 to pass through the gap between the first sealing block 1113 and the first receiving groove 1111 and extend to the outside of the powder hopper 11, the installation of the sealing membrane 22 can be simplified. Under the premise of ensuring the sealing performance at the first through groove 1112, the free section 222 of the sealing membrane 22 can be smoothly pulled out, taking into account both sealing reliability and ease of operation.

[0044] Furthermore, the housing 1 also includes a first end cap, which is installed at the first end of the toner cartridge 11 and the developing cartridge 12, and covers the ends of the toner cartridge 11 and the developing cartridge 12. The first end cap has a third through groove at the first through groove 1112, and the free section 222 of the sealing film 22 extends to the outside of the first end cap through the third through groove. It is understood that the second ends of the toner cartridge 11 and the developing cartridge 12 are also provided with end caps.

[0045] The first end cap is provided with a third through groove, which on the one hand provides a channel for the sealing film 22 to extend to the outer end of the regeneration treatment box 100, making it easier for the user to tear it off from the outer end of the regeneration treatment box 100, with a larger operating space and smoother tearing; on the other hand, the first end cap closes to the end of the powder hopper 11, limiting the first sealing block 1113 filled in the first receiving groove 1111, preventing the first sealing block 1113 from shifting or loosening during use, so that the first sealing block 1113 reliably seals the first through groove 1112, thereby preventing toner from leaking from the first through groove 1112 and the third through groove, further ensuring the stability and durability of the sealing structure.

[0046] In addition, the toner hopper 11 is provided with a toner filling port 112; the cartridge body 1 also includes a sealing plug 1121 detachably connected to the toner filling port 112, which is used to seal the toner filling port 112. When the toner in the remanufacturing cartridge 100 is depleted, the user can replenish the toner through the toner filling port 112 without replacing the entire cartridge, thereby effectively extending the service life of the remanufacturing cartridge 100 and significantly reducing the user's printing costs. Furthermore, during the remanufacturing process of the remanufacturing cartridge 100, toner can be filled into the toner hopper 11 through the toner filling port 112, simplifying the toner filling process and improving remanufacturing efficiency. At the same time, the sealing plug 1121 can form a reliable seal on the toner filling port 112, effectively preventing toner leakage from the toner filling port 112 during transportation, storage, and use, ensuring the sealing performance and cleanliness of the remanufacturing cartridge 100.

[0047] The developing roller 31 is rotatably mounted at the developing chamber 12 and can rotate around its own axis; the developing roller 31 is located at the outlet of the developing chamber 12. A sealing scraper 32 is mounted on the housing and contacts the outer peripheral surface of the developing roller 31. A powder discharge scraper 33 is mounted on the housing and contacts the outer peripheral surface of the developing roller 31; the sealing scraper 32 and the powder discharge scraper 33 are respectively located on opposite sides of the developing roller 31. A drive wheel assembly 34 is mounted at the second end of the powder chamber 11 and is connected to the developing roller 31.

[0048] It should be noted that the arrangement and function of the developing roller 31, sealing scraper 32, and powder discharge scraper 33 are the same as those of existing processing boxes, so they will not be described in detail. In addition, the processing box also includes a photosensitive drum, charging roller, stirring rack, etc. Similarly, since their arrangement and function are the same as those of existing processing boxes, they will not be described in detail either.

[0049] Second embodiment of the regeneration treatment box Combination Figures 7 to 10 The difference between this embodiment and the first embodiment of the regeneration processing box lies in the placement of the sealing film 22, the structural features of the powder chamber 11, the developing chamber 12, and the end cap. The following is a detailed description of these differences: In this embodiment, the regeneration processing box 100 is equipped with a powder feeding roller 35, so its developing chamber 12 has a larger space. Therefore, the sealing film 22 is not located inside the powder chamber 11, but inside the developing chamber 12. Correspondingly, the first end wall 11 of the powder chamber 11 is no longer provided with the first through groove 1112, the regeneration processing box 100 is no longer provided with the first sealing block 1113, and the end cover is no longer provided with the third through groove.

[0050] Furthermore, since the sealing film 22 is located inside the developing chamber 12 (i.e., the sealing film 22 is located on the side of the sealing strip 21 facing the developing chamber 12), the installation method of the sealing film 22 is changed, specifically: The sealing section 221 of the sealing film 22 is bonded to the side of the sealing strip 21 facing the inside of the developing chamber 12; the second end wall 121 of the developing chamber 12 is provided with a second through groove 1212 on the first end side of the sealing section 221, and the free section 222 extends out of the developing chamber 12 through the second through groove 1212.

[0051] Furthermore, the second end wall 121 of the developing chamber 12 has a second receiving groove 1211, and a second through groove 1212 is located at the bottom of the second receiving groove 1211. A second sealing block 1213 is filled within the second receiving groove 1211, and a free segment 222 passes through the gap between the second sealing block 1213 and the second receiving groove 1211. By opening the second through groove 1212 at the bottom of the second receiving groove 1211 of the second end wall 121, the second sealing block 1213 can be directly embedded within the second receiving groove 1211, thereby fully utilizing the existing structural space of the second end wall 121 (i.e., the second receiving groove 1211) without the need for an additional fixing structure for the second sealing block 1213, simplifying the regeneration process of the processing cartridge.

[0052] After the second sealing block 1213 is filled into the second receiving groove 1211, it can effectively seal the second through groove 1212, preventing the toner in the toner hopper 11 from leaking out through the second through groove 1212. In addition, by allowing the free section 222 of the sealing membrane 22 to pass through the gap between the second sealing block 1213 and the second receiving groove 1211 and extend to the outside of the toner hopper 11, the installation of the sealing membrane 22 can be simplified, and the free section 222 of the sealing membrane 22 can be smoothly pulled out while ensuring the sealing performance at the second through groove 1212, thus taking into account both sealing reliability and ease of operation.

[0053] Furthermore, the housing 1 also includes a second end cap 14 (which functions the same as the first end cap in the first embodiment of the regeneration processing housing, replacing the first end cap to fit the structure of the toner cartridge 11 and the developing cartridge 12 in this embodiment). The second end cap 14 is installed at the first end of the toner cartridge 11 and the developing cartridge 12, and the second end cap 14 covers the ends of the toner cartridge 11 and the developing cartridge 12. The second end cap 14 has a fourth through groove 141 at the second through groove 1212, and the free section 222 of the sealing film 22 extends out to the outside of the second end cap 14 through the fourth through groove 141. It is understood that the second ends of the toner cartridge 11 and the developing cartridge 12 are also provided with end caps.

[0054] The second end cap 14 is provided with a fourth through groove 141. On the one hand, it provides a channel for the sealing film 22 to extend to the outer end of the regeneration treatment box 100, making it easier for the user to tear it off from the outer end of the regeneration treatment box 100. The operating space is larger and the tearing is smoother. On the other hand, the second end cap 14 closes to the end of the powder hopper 11, which limits the second sealing block 1213 filled in the second receiving groove 1211, preventing the second sealing block 1213 from shifting or loosening during use. This ensures that the second sealing block 1213 reliably seals the second through groove 1212, thereby preventing toner from leaking from the second through groove 1212 and the fourth through groove 141, and further ensuring the stability and durability of the sealing structure.

[0055] In this embodiment, the orthographic projection of the first opening 131 on the partition 13 completely coincides with the orthographic projection of the second opening 211 on the partition 13; as an alternative, the orthographic projection of the first opening 131 on the partition 13 is located within the orthographic projection of the second opening 211 on the partition 13. The powder feeding roller 35 is disposed in the developing chamber 12, and the powder feeding roller 35 can rotate around its own axis, and the powder feeding roller 35 is connected to the transmission wheel assembly 34.

[0056] By defining the relative positional relationship between the first opening 131 and the second opening 211, it can be ensured that when the toner in the toner hopper 11 flows through the first opening 131 to the developing hopper 12, the sealing strip 21 will not block the first opening 131. The toner can pass smoothly through the opening area on the partition 13 and the sealing strip 21, effectively preventing the toner from accumulating or stagnating at the junction of the partition 13 and the sealing strip 21, and ensuring the continuity and stability of toner delivery.

[0057] As can be seen, for the regeneration processing box 100 equipped with the powder feeding roller 35, the presence of the powder feeding roller 35 provides sufficient internal space for the developing chamber 12. Therefore, the sealing film 22 can be directly arranged inside the developing chamber 12, and the pulling end of the sealing film 22 can be led out to the outside of the developing chamber 12 by means of the second through groove 1212 on the second end wall 121 of the developing chamber 12, which can also ensure that the sealing film 22 can be easily removed.

[0058] Both solutions provided by this invention do not require destructive cutting and subsequent reconnection of the powder chamber 11 and the developing chamber 12 during the regeneration process. This not only simplifies the regeneration process and reduces regeneration costs, but also effectively maintains the integrity and stability of the original structure of the processing box, thereby improving the assembly efficiency and product quality of the regeneration processing box 100.

[0059] First embodiment of the regeneration method for the processing box The regeneration method provided in this embodiment is used for the installation of the seal 2 of the regeneration box 100 in the first embodiment of the above-mentioned regeneration box. Specifically, the installation steps of the seal 2 include: Place the sealing strip 21 inside the developing chamber 12, fix the first side of the sealing strip 21 to the partition 13, and connect the second opening 211 of the sealing strip 21 to the first opening 131 of the partition 13.

[0060] A first through groove 1112 is provided on the first end wall 11 of the powder hopper 11. The sealing section 221 of the sealing film 22 is bonded to the first surface of the sealing strip 21, so that the sealing section 221 is located inside the first opening 131 of the partition 13 and covers the second opening 211 of the sealing strip 21. The first end of the sealing section 221 is located on the same side of the powder hopper 11 as the first end wall 11.
