Description

Technical Field

[0001] This utility model relates to the field of toner cartridge technology, specifically to a structurally optimized and improved toner cartridge. Background Technology

[0002] In the field of office automation equipment, there have always been several technical problems that urgently need to be solved in the core component of laser printers: the toner cartridge.

[0003] Traditional toner cartridges typically use a double-sided locking device to secure the toner cartridge. This design requires two symmetrical locking components and connecting rods, which increases the number of parts and complicates the assembly process, thus increasing manufacturing costs and affecting production efficiency.

[0004] In terms of chip mounting, current technologies generally adopt a split structure design, where the chip socket and chip frame are independent components that are assembled together. This structure inevitably has assembly gaps, which can easily lead to poor contact due to vibration during transportation and use, thus causing printer recognition failures. At the same time, the mechanical strength of the split structure is limited, making it susceptible to damage when subjected to external impacts.

[0005] More importantly, traditional toner cartridges have significant flaws in their toner delivery systems. When a cartridge has been idle for an extended period, toner can easily bridge, forming clumps that cause poor toner supply upon restarting. This directly impacts print quality stability, particularly causing uneven density and streaks in initial prints, severely affecting the user's printing experience. Utility Model Content

[0006] The purpose of this utility model is to provide a reasonably designed and structurally optimized toner cartridge that addresses the defects and shortcomings of existing technologies and solves the aforementioned deficiencies.

[0007] To achieve the above objectives, the utility model provides the following technical solution: it includes a drum body, a transmission gear set is provided on one side of the drum body, a protective shell is provided on the same side of the drum body, the protective shell covers the outside of the transmission gear set, a locking element is movably provided on the protective shell, a toner cartridge is provided at the bottom of the drum body, a developing roller and a toner feeding roller are provided inside the drum body, both the developing roller and the toner feeding roller are connected to the transmission gear set, and a chip skeleton is provided on the side of the drum body away from the transmission gear set.

[0008] Preferably, the transmission gear set includes a drive gear disposed on one side of the drum housing, the drive gear being connected to a drive assembly; a first transmission gear is disposed at one end of the powder feeding roller, the drive gear meshing with the first transmission gear; a driven gear is disposed on one side of the first transmission gear, the driven gear meshing with the first transmission gear; a second transmission gear is disposed at the same end of the developing roller, the second transmission gear meshing with the driven gear; the first transmission gear includes an upper gear, the upper gear meshing with the drive gear; and a lower gear is disposed at the bottom of the upper gear, the lower gear meshing with the driven gear.

[0009] Preferably, the upper gear is coaxially arranged with one end of the powder feeding roller, and the lower gear is eccentrically arranged with the upper gear.

[0010] Preferably, a chip holder is integrally formed on the chip skeleton, and several reinforcing ribs are integrally formed on the outer wall of the chip skeleton.

[0011] Preferably, the protective shell is provided with a movable groove, the locking member is movably disposed within the locking member, the toner cartridge is provided with a docking groove, and one end of the locking member is disposed within the docking groove.

[0012] The beneficial effects of adopting the above structure are: This invention reduces the number of components, such as locking parts and connecting rods, by designing the traditional double-sided locking structure into a single-sided independent locking structure. This simplification significantly optimizes the assembly process, making the assembly steps more concise and effectively shortening production time. In mass production, the reduction in the number of parts leads to a decrease in material costs, while simplifying supply chain management. The increased production efficiency leads to an increase in output per unit time, creating considerable economic benefits for enterprises.

[0013] This invention completely eliminates the assembly gap problem of traditional split structures by adopting an integrated design of chip skeleton and chip socket. This structure effectively avoids component loosening and displacement caused by transportation vibration or long-term use, ensuring the stability of electrical connection. The integrated structure integrates all stress points, which significantly improves the overall mechanical strength. The design of reinforcing ribs further enhances the structure's impact resistance and wear resistance. This improvement greatly reduces the incidence of printer recognition failure and extends the service life of toner cartridge.

[0014] This invention utilizes an eccentric shaft design in the transmission gear to generate controlled mechanical micro-vibrations during toner delivery. These vibrations effectively break up toner bridging or clumps formed due to long-term static storage, ensuring that the toner is always delivered evenly. The improved structure significantly enhances print quality, improves the stability of toner delivery, and effectively avoids common defects such as uneven print density and streaks.

Detailed Implementation

[0017] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0018] like Figures 1-7As shown, the present invention proposes a structurally optimized and improved toner cartridge, which includes a toner cartridge body 1, a transmission gear set 2 on one side of which is provided. The transmission gear set 2 includes a drive gear 20 on one side of the toner cartridge housing. The drive gear 20 is connected to the printer drive assembly. A transmission gear 21 is provided at one end of the toner feeding roller 11. The drive gear 20 and the transmission gear 21 are meshed together. The transmission gear 21 includes an upper gear 22 and a lower gear 23. The upper gear 22 is coaxial with one end of the toner feeding roller 11, while the lower gear 23 is eccentrically mounted with the upper gear 22. This eccentric design can generate controlled mechanical micro-vibration during toner delivery, effectively breaking up toner bridging or clumps formed by long-term static storage, ensuring that the toner is always delivered in a uniform state, thereby significantly improving the output quality of the first printed product. A driven gear 24 is provided on one side of the transmission gear 21, and the lower gear 23 is meshed with the driven gear 24. A transmission gear 25 is provided at the same end of the developing roller 10, and the transmission gear 25 is meshed with the driven gear 24, thus forming a complete power transmission path. A protective shell 4 is provided on the same side of the drum body 1. The protective shell 4 completely covers the outside of the transmission gear set 2, providing sufficient protection for the gear set. The protective shell 4 has a dedicated movable groove 40 inside, and the locking member 41 is movably installed in the movable groove 40. Correspondingly, the toner cartridge 5 has a positioning docking groove 50, and one end of the locking member 41 is inserted into the docking groove 50. This design changes the traditional double-sided locking structure to a single-sided independent locking structure, directly eliminating a locking member 41 and multiple parts such as the long rod connecting the two. This design not only simplifies the overall structure, but also optimizes the assembly process, effectively reduces assembly steps and time, significantly improves production efficiency, and generates considerable economic benefits in the mass production process. A chip frame 3 is provided on the side of the toner cartridge body 1 away from the transmission gear set 2. The chip frame 3 adopts an integrated design and directly forms a chip holder 30. At the same time, several reinforcing ribs 31 are integrally formed on the outer wall of the chip frame 3. This integrated design completely eliminates the assembly gap and moving parts in the traditional split design, and completely avoids problems such as loosening, displacement and poor contact of the chip holder 30 caused by transportation vibration or long-term use. The bottom of the drum body 1 is provided with a toner box 5. Inside the drum body 1 are a developing roller 10 and a toner feeding roller 11. The developing roller 10 and the toner feeding roller 11 are both connected to the transmission gear set 2 to jointly complete the toner delivery and developing process.
