Description

Technical Field

[0001] The utility model relates to the technical field of toner cartridges, and particularly to a toner cartridge with an integrated counting and reset end cap. Background Art

[0002] With the popularization of office automation equipment, printers, as an indispensable part of daily office work, play an important role in enterprises and personal life. As one of the core consumables of printers, the design of toner cartridges directly affects the working efficiency of printers and the user experience. Traditional toner cartridges usually consist of multiple independent components, and the connection and cooperation between these components often rely on complex mechanical structures, which not only increase the production cost but also may lead to problems such as inconvenient maintenance and shortened service life.

[0003] Specifically, in the existing toner cartridge design, the counting gear is usually installed on the gear end of the toner cartridge body together with the gear assembly of the toner cartridge, and then cooperates with the reset member and the trigger member installed on the gear side cover to jointly complete the functions of counting and triggering the toner cartridge in the printer and resetting the counting gear when recycling the toner cartridge. However, this design makes the cooperation between the counting gear and the reset member and the trigger member a technical problem. Once there is any tiny error in the installation process, it may cause the counting gear to fail to correctly trigger the printer to identify the toner cartridge when the toner cartridge is installed in the machine, or when recycling is required, the reset member cannot smoothly reset the counting gear. These problems seriously affect the user experience and the reliability of the equipment.

[0004] On the other hand, the power supply method of the developing roller and the powder feeding roller in traditional toner cartridges is usually carried out by forking the conductive sheet installed on the conductive bracket at the conductive end of the toner cartridge and contacting the developing roller and the powder feeding roller. The design of this conductive sheet not only increases the manufacturing cost but also increases the complexity of assembly due to its complex structure, which further leads to the problem of insufficient current caused by poor contact, ultimately affecting the printing quality.

[0005] Therefore, it is imperative to design a toner cartridge with an integrated counting and reset end cap. Summary of the Utility Model

[0006] Aiming at the defects of the above-mentioned existing technologies, the utility model provides a toner cartridge with an integrated counting and reset end cap, aiming to solve the problems of difficult cooperation and easy error between the counting gear and the reset member and the trigger member in traditional toner cartridges, as well as the complex power supply method, high cost and easy poor contact of the developing roller and the powder feeding roller.

[0007] To achieve the above object, the technical solution adopted by the present utility model is: a toner cartridge with an integrated counting and reset end cap, including a toner cartridge body, wherein gear ends and conductive ends are respectively arranged at both ends of the toner cartridge body, a developing roller and a powder feeding roller are arranged adjacent to each other in the toner cartridge body, and are jointly positioned by a positioning plate at the gear end and a conductive bracket at the conductive end. A conductive sheet of the conductive bracket is connected to the developing roller. A gear side cover is arranged outside the gear end. A counting gear, a reset component that can move left and right relative to the gear side cover, an elastic component, and a triggering component that moves along an arc path outside the gear side cover are arranged on the gear side cover. The reset component blocks the movement path of a blocking protrusion inside the counting gear. The elastic component is pressed by a pressing component on the inner rotating shaft of the counting gear to store reset potential energy. The triggering component is located on the movement path of a triggering protrusion outside the counting gear.

[0008] Based on the above, the beneficial effects of a toner cartridge with an integrated counting and reset end cap are as follows: it solves the problems of difficult cooperation, easy error between the counting gear and the reset component and the triggering component in the traditional toner cartridge, as well as the complex power supply mode, high cost and easy contact failure between the developing roller and the powder feeding roller; mainly reflected in:

[0009] In the present utility model, the counting gear, the reset component, the elastic component, and the triggering component are simultaneously integrated on a gear side cover. When the toner cartridge is installed on the machine, the counting gear rotates, drives the triggering component to trigger the sensing element in the printer through the triggering protrusion, so that the toner cartridge is recognized when installed on the machine. After successful recognition, the blocking protrusion of the counting gear just touches the reset component and then stops rotating. During the rotation of the counting gear, the elastic component is squeezed by the pressing component on the inner rotating shaft of the counting gear to accumulate reset potential energy. When the reset component is pushed away from the blocking protrusion, the elastic component immediately pushes the pressing component through the accumulated reset potential energy, so that the counting gear can rotate and reset to the initial position. In summary, since all components are pre-installed on the gear side cover, the accuracy of the cooperation between each component is greatly enhanced, problems caused by installation errors are completely avoided, the accuracy of the printer's recognition of the toner cartridge is improved, at the same time, the reset operation of the toner cartridge is facilitated, and the reliability of the device and the user experience are enhanced;

[0010] The conductive sheet of the conductive bracket of the present utility model is only connected to the developing roller, and directly conducts the electrical signal between the developing roller and the powder feeding roller through a positioning plate made of conductive material, reducing the assembly complexity caused by the bifurcated structure of the conductive sheet, effectively avoiding the problem of insufficient current caused by poor contact, and thus improving the printing quality and stability.

[0011] Further, a pre-installation groove is arranged inside the gear side cover, and a positioning central axis is arranged in the middle of the pre-installation groove. The counting gear is rotatably sleeved on the positioning central axis.

[0012] Based on the above, the beneficial effect of the pre-installation groove is to pre-install the counting gear on the gear side cover through the positioning central axis.

[0013] Furthermore, a reset member slide is provided at the top of the gear side cover. The reset assembly includes a reset member, a reset spring, and a spring mounting block. The spring mounting block is adapted to a slide groove at one end of the reset member slide. The reset member is slidably connected to the reset member slide. The reset spring is connected between the reset member and the spring mounting block. The extended abutting rod at the lower end of the reset member is located on the movement path of the blocking convex block.

[0014] Based on the above, the beneficial effect of the reset member slide is to guide the sliding direction of the reset member; the beneficial effect of the reset member is that by blocking the extended abutting rod on the movement path of the blocking convex block of the counting gear, it prevents the counting gear from rotating again following the gear assembly at the gear end after the toner cartridge completes the machine recognition. At the same time, when the toner cartridge is recycled and refilled for use, pushing it away from the blocking convex block can make the counting gear rotate and reset, allowing the counting gear to mesh with the gear assembly again, so as to recognize the machine again during use; the beneficial effect of the reset spring is that after pushing the reset member to reset the counting gear, the reset spring quickly pushes the reset member back to its original position to be in contact with the blocking convex block during the next round of machine recognition, preventing the counting gear from resetting prematurely; the beneficial effect of the spring mounting block is to fix the position of the reset spring, ensuring that the spring will not shift or fall off during the working state.

[0015] Furthermore, a positioning post is provided on one side of the pre-installation groove. A limiting buckle is provided on the inner wall of the gear side cover on one side of the positioning post. The elastic member has a positioning end, a sleeved end, and an energy storage end. The sleeved end is sleeved on the positioning post. The positioning end is in positioning cooperation with the inner side of the limiting buckle. The energy storage end is pressed by an extrusion member on the inner rotating shaft of the counting gear to store reset potential energy.

[0016] Based on the above, the beneficial effect of the positioning post is to provide a stable support point for the elastic member; the beneficial effect of the limiting buckle is to limit the position of the elastic member to prevent unnecessary displacement during the working process; the beneficial effect of the positioning end is to ensure the correct installation of the elastic member in the limiting buckle and avoid misalignment of the elastic member during use; the beneficial effect of the sleeved end is to enable the elastic member to be firmly installed on the positioning post; the beneficial effect of the energy storage end is to efficiently store and release energy through interaction with the extrusion member, promoting the effective operation of the reset mechanism.

[0017] Furthermore, a trigger slide is provided at the outer end of the gear side cover and is located on the outer side of the pre-installation groove. A trigger member is slidably mounted on the trigger slide. Both the trigger member and the trigger slide are arc-shaped structures. A driving end platform is provided on the inner side of the trigger member. The driving end platform is located on the movement path of the trigger convex block.

[0018] Based on the above, the beneficial effect of the trigger slide is to allow the trigger member to move along an arc path; the beneficial effect of the trigger member is that its arc design enables it to accurately interact with the internal sensing element of the printer; the beneficial effect of the driving end platform is to ensure that the trigger member can effectively contact the trigger boss, promoting the operation of the entire counting and reset mechanism.

[0019] Further, the positioning plate is made of a conductive material and is used to conduct the electrical signal between the developing roller and the powder feeding roller.

[0020] Further, a drum core is provided inside the toner cartridge body. A printing port is provided below the drum core of the toner cartridge body. An anti-paper jamming support member is installed on the printing port. An installation guide plate is provided on one side of the printing port close to the drum core. A plurality of guide member mounting posts are evenly distributed on the installation guide plate. The anti-paper jamming support member is positioned and installed on the installation guide plate through the plurality of guide member mounting posts.

[0021] Based on the above, the beneficial effect of the anti-paper jamming support member is to reduce the situation of paper jamming during printing by optimizing the design of the printing port, improving the printing efficiency.

[0035] A pre-installation groove 21 is arranged inside the gear side cover 2. A positioning central axis 211 is arranged in the middle of the pre-installation groove 21. The counting gear 3 is rotatably sleeved on the positioning central axis 211.

[0036] A reset part slide 22 is provided at the top of the gear side cover 2. The reset assembly 4 includes a reset part 41, a reset spring 42, and a spring mounting block 43. The spring mounting block 43 is fitted into a slide groove opening 221 at one end of the reset part slide 22. The reset part 41 is slidably connected to the reset part slide 22. The reset spring 42 is connected between the reset part 41 and the spring mounting block 43. The extended abutting rod 411 at the lower end of the reset part 41 is located on the movement path of the blocking convex block 31.

[0037] A positioning post 23 is provided on one side of the preloading groove 21. A limit buckle 24 is provided on the inner wall of the gear side cover 2 on one side of the positioning post 23. The elastic member 5 is provided with a positioning end 51, a sleeving end 52, and an energy storage end 53. The sleeving end 52 is sleeved on the positioning post 23. The positioning end 51 is positioned and fitted inside the limit buckle 24. The energy storage end 53 is pressed by a pressing member 33 on the inner rotating shaft 32 of the counting gear 3 to store reset potential energy.

[0038] A trigger slide 25 is provided at the outer end of the gear side cover 2 and is located outside the preloading groove 21. The trigger member 6 is slidably mounted on the trigger slide 25. Both the trigger member 6 and the trigger slide 25 are arc-shaped structures. A driving end platform 61 is provided on the inner side of the trigger member 6. The driving end platform 61 is located on the movement path of the trigger convex block 34.

[0039] The positioning plate 111 is made of a conductive material and is used to conduct the electrical signal between the developing roller 13 and the powder feeding roller 14.

[0040] A drum core 15 is provided inside the toner cartridge body 1. A printing port 16 is provided below the drum core 15 near the toner cartridge body 1. An anti-paper jamming support member 17 is installed on the printing port 16. An installation guide plate 161 is provided on one side of the printing port 16 near the drum core 15. A plurality of guide member mounting posts 162 are evenly distributed on the installation guide plate 161. The anti-paper jamming support member 17 is positioned and installed on the installation guide plate 161 through the plurality of guide member mounting posts 162.

[0041] In summary, the specific implementation manner of the present invention is as follows: First, the driving gear of the gear assembly in the toner cartridge is connected to the driving unit inside the printer. The counting gear 3 pre-loaded inside the preloading groove 21 of the gear side cover 2 is driven to rotate by the gear assembly on the gear end 11. As the counting gear 3 rotates, the trigger convex block 34 on its outer side contacts the trigger member 6 located outside the gear side cover 2. The trigger member 6 moves along the arc path of the trigger slide 25, triggering the sensing element inside the printer to complete the identification of the toner cartridge.

[0042] When the counting gear 3 rotates to a certain angle, the blocking bump 31 on its inner side touches the extended abutting rod 411 of the reset member 41 in the reset assembly 4. At the same time, the pressing member 33 on the inner side of the counting gear 3 presses the energy storage end 53 of the elastic member 5, causing the elastic member 5 to compress and store the potential energy required for reset. Since the extended abutting rod 411 of the reset member 41 continuously blocks the blocking bump 31, even if the gear assembly continues to rotate, the counting gear 3 will not rotate because its empty tooth portion faces the meshing portion with the gear assembly;

[0043] When the toner cartridge is exhausted and refilled with toner, the user can manually push the reset member 41 out of the position blocking the blocking bump 31. After the reset member 41 is separated from the blocking bump 31, the compressed reset spring 42 will quickly push the reset member 41 back to its initial position. At the same time, the compressed elastic member 5 releases energy, pushing the counting gear 3 to rotate to the initial position to complete the reset action, facilitating the counting and identification process for the next use.

[0044] The above is only the optimal solution embodiment of the present invention and is not used to limit the present invention. Various modifications or substitutions made by those skilled in the art to the present invention without departing from the essence and protection scope of the present invention should also be within the protection scope of the present invention.
