Description

Technical Field

[0001] This utility model relates to the field of laser printer technology, specifically a toner cartridge cleaning device for laser printers. Background Technology

[0002] As a key consumable in laser printers, toner cartridges have a limited lifespan and typically need to be replaced after printing a certain number of pages. Traditionally, used toner cartridges are discarded, which not only increases user costs but also wastes resources and pollutes the environment. To address these issues, toner cartridges are refilled and reused. However, during refilling, a lot of old toner adheres to the inner wall of the cartridge. This old toner causes uneven distribution of the newly added toner, resulting in poor mixing between the old and new toner and affecting print quality. Utility Model Content

[0027] Example 2

[0028] Based on Embodiment 1, the cleaning assembly includes: a rotating disk a2, a rotating disk b21, a rotating rod 22, a scraper 23, and a motor 24. The rotating disk a2 and rotating disk b21 are respectively located at opposite ends inside the toner cartridge 1. A rotating rod 22 is located near the edge between the rotating disks a2 and b21. Multiple scrapers 23 arranged in a circular array are fixedly connected to the outside of the rotating rod 22. The scrapers 23 are in contact with the inner wall of the toner cartridge 1. A motor 24 is fixedly installed inside the equipment housing a11. The drive shaft at one end of the motor 24 is connected to the rotating disk a2. A connecting rod 25 is fixedly connected between the rotating disk a2 and the rotating disk b21. Several stirring rods 26 are fixedly connected to the outside of the connecting rod 25. A discharge port 27 is opened at the center of the shaft on one side of the rotating disk b21. A movable groove 28 communicating with the inside of the equipment shell b12 is opened on the inner wall of one side of the toner box 1. A fixed ring 29 is fixedly connected to the inner wall of the movable groove 28. Several teeth 210 are opened on the inner diameter of the fixed ring 29. One end of the rotating rod 22 extends to the movable groove 28 and is fixedly connected to a gear 211. The gear 211 meshes with the teeth 210.

[0029] When cleaning the toner inside the toner cartridge 1, the rotating rod 22 and scraper 23 are connected to the gear 211. The rotating rod 22 and gear 211 are detachable. The motor 24 is started to drive the rotating disk a2 to rotate, which in turn drives the rotating disk b21 to rotate through the connecting rod 25, thereby driving the rotating rod 22 to move. When the rotating rod 22 moves, it drives the gear 211 to move. When the gear 211 moves, it meshes with the teeth 210 of the fixed ring 29, thereby driving the rotating rod 22 to rotate. When the rotating rod 22 rotates, it drives the external scraper 23 to rotate. The rotating scraper 23 can clean the toner adhering to the inner wall of the toner cartridge 1. As the rotating disk a2 and rotating disk b21 rotate, the rotating scraper 23 cleans the inner wall of the toner cartridge 1. After cleaning, the rotating rod 22 and scraper 23 are removed.
