Description

Technical Field

[0001] This utility model relates to the field of toner cartridge technology, specifically a toner cartridge with a cleaning scraper stabilizing structure. Background Technology

[0002] During the imaging process, after the photosensitive drum surface is charged and exposed to form an electrostatic latent image, toner is attached to the latent image area by the developing roller, and then transferred to paper. To ensure the accuracy of the next imaging round, the residual toner on the photosensitive drum surface must be thoroughly removed, a function usually performed by a cleaning blade.

[0003] The cleaning blade in a traditional toner cartridge typically consists of a rubber strip and a blade holder. One end of the rubber strip is fixed to the blade holder, while the other end rests against the surface of the photosensitive drum at a certain angle and with pressure, relying on friction to scrape away residual toner.

[0004] However, during long-term use, the rubber strip is prone to wear due to vibrations caused by the high-speed rotation of the photosensitive drum, material deformation caused by temperature changes, and uneven local resistance caused by toner accumulation. Most existing rubber strips are connected to the cutter holder via adhesive bonding. When the rubber strip needs to be replaced after wear, it is usually necessary to remove the old rubber strip, including cleaning the residual adhesive layer on the cutter holder surface, and then repositioning and attaching the new rubber strip. This replacement process is not only cumbersome and time-consuming, but also easily causes scratches or unevenness to the cutter holder surface when removing the old rubber strip. Therefore, this utility model aims to provide a toner cartridge that facilitates rubber strip replacement for users. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a toner cartridge with a cleaning scraper stabilizing structure, which facilitates user replacement of the adhesive strip on the blade holder, thus solving the problem of inconvenient replacement of the adhesive strip on the blade holder in existing technologies.

[0006] To achieve the above objectives, this utility model provides a toner cartridge with a cleaning scraper stabilizing structure, including a scraper holder mounted on the toner cartridge body, an adhesive strip fixedly sleeved on a replacement plate, and a disassembly assembly for detachably fixing the replacement plate to the free end of the scraper holder. The disassembly assembly includes a locking block, a locking rod, a movable locking element, and a magnetic suction element.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Please refer to Figures 1 to 8 According to an embodiment of this utility model, a technical solution is provided: a toner cartridge with a cleaning scraper stabilizing structure, including a scraper holder 2 mounted on the toner cartridge body 1, an adhesive strip 3 fixedly sleeved on a replacement plate 4, and a disassembly assembly for detachably fixing the replacement plate 4 to the free end of the scraper holder 2; the disassembly assembly includes a locking block 5, a locking rod 6, a movable locking component, and a magnetic suction component 7; the replacement plate 4 and the scraper holder 2 are respectively provided with a locking groove 8 and a locking groove 9 suitable for the movable insertion of the locking block 5, and the end of the locking block 5 is provided with a stop... The receiving groove 11, the locking rod 6 and the abutment groove 11 are threadedly connected; the side wall of the locking block 5 is provided with a moving groove 12 that communicates with the abutment groove 11, and the moving locking member is slidably disposed in the moving groove 12. The inner wall of the second locking groove 9 is provided with a third locking groove 10 suitable for the moving locking member to be inserted; when the locking rod 6 is accommodated by the abutment groove 11, the moving locking member is simultaneously inserted into the moving groove 12 and the third locking groove 10; when the locking rod 6 is not accommodated by the abutment groove 11, the moving locking member is completely attracted into the moving groove 12 and the abutment groove 11 by the magnetic attractor 7.

[0021] The toner cartridge with the cleaning scraper stabilization structure described above allows for quick installation of the replacement plate 4 to the free end of the tool holder 2. First, the replacement plate 4 is pushed to allow the locking block 5 to sequentially enter the locking groove 8 and the second locking groove 9. Then, the locking rod 6 is tightened into the abutment groove 11. During this process, the locking rod 6 gradually pushes into the abutment groove 11, simultaneously forcing the moving locking element to extend outward into the third locking groove 10, thus securing the replacement plate 4 to the tool holder 2. Conversely, when the user needs to remove the replacement plate 4, the locking rod 6 is loosened to allow it to exit the abutment groove 11. At this time, the magnetic component 7 pulls the moving locking element back into the moving groove 12 and the abutment groove 11, allowing the locking block 5 to slide smoothly out of the second locking groove 9, thus achieving quick removal. This avoids the problem of users having to replace the entire tool holder 2 due to the adhesive strip 3 used in traditional structures, saving costs.

[0022] In this embodiment, the movable locking component includes a movable block 13 and a limiting block 14. The movable block 13 is slidably disposed in the movable groove 12, and a limiting groove 16 is formed on the inner wall of the movable groove 12. The limiting block 14 is slidably disposed in the limiting groove 16. The movable block 13 and the limiting block 14 are fixed. The movable block 13 has an inclined surface on the side facing the locking rod 6. With this configuration, the movable block 13 will be subjected to the squeezing force at its end when the locking rod 6 is pushed forward. The inclined surface can convert the axial thrust of the locking rod 6 into a component force that causes the movable block 13 to move radially outward along the movable groove 12, thereby allowing the movable block 13 to enter the locking groove 10 and achieve locking. When the locking rod 6 exits the abutment groove 11, the movable block 13 loses the outward thrust and automatically retracts into the movable groove 12 under the attraction of the magnetic suction component 7.

[0023] In this embodiment, the end of the locking rod 6 facing the moving block 13 has a frustum-shaped structure; this arrangement facilitates the end of the locking rod 6 to abut against the inclined surface of the moving block 13.

[0024] In this embodiment, the magnetic suction component 7 is fixed in the limiting groove 16 and arranged near the abutment groove 11. The magnetic suction component 7 is suitable for adsorbing the limiting block 14. With this arrangement, when the locking rod 6 exits the abutment groove 11, the magnetic suction component 7 can generate an adsorption force on the limiting block 14 and pull it back into the limiting groove 16, so as to drive the moving block 13 to retract synchronously to the depth of the moving groove 12.

[0025] In this embodiment, a limiting part 17 is fixed at the end of the locking block 5. The limiting part 17 is provided with an insertion port 19 that communicates with the abutment groove 11. The insertion port 19 is suitable for the locking rod 6 to be inserted. This arrangement is to limit the locking block 5 from being completely accommodated by the locking groove 8 and the locking groove 9, so that the user can pull out the locking block 5.

[0026] In this embodiment, a receiving groove 20 is provided on the limiting part 17, and a limiting part 28 is fixed to the end of the locking rod 6. The receiving groove 20 is suitable for accommodating at least part of the limiting part 2 18. This arrangement makes it convenient for the user to pull out the locking rod 6.

[0027] In this embodiment, the receiving groove 20 is adapted to completely accommodate the second limiting part 18; this arrangement facilitates the complete concealment of the second limiting part 18 into the receiving groove 20, preventing the protrusion of the second limiting part 18 from affecting other components.

[0028] In this embodiment, the limiting part 2 18 is provided with a torsion groove 21 in a cross shape; with this configuration, when the user needs to pull out the locking rod 6, a screwdriver can be inserted into the torsion groove 21 and rotated to facilitate the user pulling out the locking rod 6.

[0029] In this embodiment, the adhesive strip 3 has a sleeve groove 15, and the replacement plate 4 has an L-shaped structure. The end of the replacement plate 4 is fixed in the sleeve groove 15. With this arrangement, by fixing the replacement plate 4 in the sleeve groove 15, the adhesive strip 3 is more tightly prevented from falling off the replacement plate 4.

[0030] In this embodiment, the end of the replacement plate 4 is fixed in the sleeve groove 15 by adhesive; this setting is to further prevent the adhesive strip 3 from detaching from the replacement plate 4.

[0031] It should be noted that all components used in this application are standard parts that can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets and welding that are mature in the prior art. The mechanical parts and electrical equipment adopt conventional models in the prior art. The circuit connection adopts conventional connection methods in the prior art.
