Description

Technical Field

[0001] This utility model relates to the field of printing consumables, and in particular to a toner cartridge that is easy to assemble. Background Technology

[0002] Toner cartridges are toner supply devices used in photocopying equipment, providing toner for printing / copying. A typical toner cartridge consists of a cartridge body, a toner-stirring roller, and a drive gear. The drive gear connects to the toner-stirring roller, and through a drive head, it interfaces with the drive mechanism on the photocopying equipment, thereby driving the toner-stirring roller to agitate the toner inside the cartridge. However, in existing toner cartridges, the drive gear and drive head are an integrated structure, making it impossible to match different models of drive gears with drive heads. This increases the variety and quantity of products manufacturers need to stock, resulting in significant inventory pressure. Furthermore, when the drive head or drive gear is damaged, both the drive head and drive gear need to be replaced, leading to considerable waste. Therefore, there is an urgent need for a toner cartridge that is easy to assemble to solve these problems. Utility Model Content

[0031] Reference Figures 1 to 4An easy-to-assemble toner cartridge includes a cartridge body 10, a mixing roller 20, a feeding roller 30, a drive gear 40, a drive head 50, and a driven gear set 60.

[0032] The box body 10 is provided with a powder outlet 13;

[0033] The powder stirring roller 20 is rotatably mounted inside the box body 10, and the powder feeding roller 30 is rotatably mounted inside the box body 10;

[0034] The drive gear 40 is mounted on one end of the mixing roller 20;

[0035] The drive head 50 is mounted on the outside of the drive gear 40 via a connector and is used to connect to the drive mechanism on the photocopying equipment.

[0036] Driven gear set 60 is rotatably mounted on box 10 with its input end meshing with drive gear 40 and its output end connected to powder feeding roller 30.

[0037] The drive gear 40 can drive the powder stirring roller 20 to stir the toner in the cartridge 10, and drive the powder feeding roller 30 to rotate through the driven gear set 60, so that the toner in the cartridge 10 is supplied to the photocopying equipment through the powder outlet 13.

[0038] In this invention, during assembly, the mixing roller 20 and the feeding roller 30 are first installed in their corresponding slots within the housing 10. Then, the driven gear set 60 is installed in a corresponding slot at one end of the housing 10, connecting the output end of the driven gear set 60 to the feeding roller 30. Next, the drive head 50 is mounted on the outside of the drive gear 40 via a connector (not shown in the figure). Preferably, the connector is a screw or bolt. The drive gear 40 is then connected to one end of the mixing roller 20 and meshed with the input end of the driven gear set 60. Finally, toner is poured into the housing 10. During use, the entire toner cartridge is placed inside the photocopying equipment, allowing the drive head 50 to engage with the drive mechanism on the photocopying equipment. In some embodiments, an assembly-friendly toner cartridge further includes a rotating... The cap 80 and retaining bow 90 are rotatably mounted on the cartridge body 10 to close or open the toner outlet 13. The middle section of the retaining bow 90 is rotatably mounted on the cartridge body 10, with one end abutting against one side of the cap 80 and the other end abutting against the other side of the cap 80, to keep the cap 80 in the closed or open position of the toner outlet 13. At this time, the cap 80 is turned to open the toner outlet 13. When the photocopying equipment is working, it will drive the drive gear 40 to rotate. When the drive gear 40 rotates, it will drive the stirring roller 20 to stir the toner in the cartridge body 10, and drive the powder feeding roller 30 to rotate through the driven gear set 60. The powder feeding roller 30 is provided with spiral blades, which can transport the toner in the cartridge body 10 in a spiral direction until it is supplied to the photocopying equipment through the toner outlet 13.

[0039] Reference Figures 1-3In some embodiments, the outer side of the drive head 50 is provided with a plurality of docking blocks 51 arranged circumferentially around its center. The drive mechanism on the photocopying device docks with the docking blocks 51, thereby driving the drive head 50 and the drive gear 40 to rotate synchronously.

[0040] Reference Figures 1-3 In some embodiments, a coupling 41 is provided on the inner side of the drive gear 40. The coupling 41 is provided with a first hook 42 and a second hook 43 arranged opposite to each other. The first hook 42 and the second hook 43 are hooked onto the mixing roller 20. During assembly, the coupling 41 on the drive gear 40 is inserted into the slot on the mixing roller 20, so that the first hook 42 and the second hook 43 pass through the slot until the first hook 42 and the second hook 43 are hooked onto the corresponding abutment on the mixing roller 20.

[0041] Reference Figures 1-4 In some embodiments, the box body 10 is provided with an installation groove 14, and the inner side wall of the box body 10 is provided with an annular abutment platform 15 located around the installation groove 14. The screw cap 80 is disposed in the installation groove 14 and is provided with a third hook 81 and a fourth hook arranged opposite to each other. The third hook 81 and the fourth hook are hooked on the annular abutment platform 15. During assembly, the screw cap 80 is inserted into the installation groove 14, so that the third hook 81 and the fourth hook pass through the installation groove 14 until the third hook 81 and the fourth hook are hooked on the annular abutment platform 15. This not only realizes the connection between the screw cap 80 and the box body 10, but also allows the screw cap 80 to rotate relative to the box body 10, thereby closing or opening the powder outlet 13.

[0042] Reference Figures 1-4 In some embodiments, the housing 10 includes a bottom box 11 and a top cover 12, the top cover 12 being mounted on the bottom box 11 to enclose a toner chamber 16 for accommodating the mixing roller 20 and the feeding roller 30.

[0043] Reference Figures 1-4 In some embodiments, the bottom box 11 and the top cover 12 are injection molded, and the top cover 12 is ultrasonically welded to the bottom box 11.

[0044] Reference Figures 1-4 In some embodiments, the cartridge 10 is provided with a toner filling port 17, through which the toner in the cartridge 10 is replenished, so that the toner cartridge can be recycled, which meets the requirements of environmental protection.

[0045] The advantages of this invention are: the structure allows the drive head to be disassembled individually, enabling it to be compatible with various drive head models and allowing for individual replacement when the drive head is damaged. This improves the versatility of the toner cartridge and the ease of disassembly and assembly, thus meeting user needs.

[0046] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
