Description

Technical Field

[0001] This utility model relates to the field of printer technology, and in particular to a toner drum developing assembly for positioning and controlling toner. Background Technology

[0002] The toner cartridge developing unit, with its precise positioning and toner control, is a crucial component in laser printers and other equipment used for developing and imaging. It typically consists of a developing roller, a magnetic roller, a toner cartridge, and a toner control device. Through a specific positioning structure, such as the interaction between the rotating shafts on both sides of the developing roller and the wheel-side positioning brackets and conductive side plates on the toner cartridge body, the axial concentricity of the developing roller is ensured, maintaining a constant compression between the developing roller and the drum core. The toner control device precisely controls the amount of toner, using structures such as a sponge-like elastomer coated with a thin film or plastic friction pads, allowing the toner to be evenly adsorbed onto the developing roller and transferred to the drum core, forming a clear image while avoiding toner waste and contamination. Currently, when cleaning the toner-contacting parts of the developing unit, a simple scraper is used. However, after prolonged use, the scraper becomes ineffective at cleaning, resulting in blurry images, thus requiring improvement. Utility Model Content

[0053] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a positioning and toner control drum developing component.

[0054] A positioning and toner control drum developing assembly includes a mounting housing 1 and a developing mechanism disposed within the mounting housing 1 for developing operations; a cleaning mechanism disposed within the mounting housing 1 for cleaning the developing mechanism. The cleaning mechanism includes: two fixing members 2, both of which are disposed on and fixedly connected to the mounting housing 1; a first micro motor 3 disposed within and fixedly connected to the fixing members 2; a first connecting shaft 4 disposed at and fixedly connected to the output end of the first micro motor 3; a first cleaning member 5 disposed on and fixedly connected to the first connecting shaft 4; a first mounting plate 6 disposed within and fixedly connected to the mounting housing 1; and a first scraper 7 disposed on and fixedly connected to the first mounting plate 6.

[0055] refer to Figure 1 and Figure 2 as well as Figure 5 In a preferred embodiment, the cleaning mechanism further includes: a drive unit disposed within the mounting housing 1 for providing power; and a cleaning unit disposed within both the drive unit and the mounting housing 1 for cleaning the developing mechanism.

[0056] refer to Figure 3 In a preferred embodiment, the driving unit includes: a second micro motor 8, which is disposed within the fixing member 2 and fixedly connected to the fixing member 2; and a second connecting shaft 9, which is disposed at the output end of the first micro motor 3 and fixedly connected to the output end of the second micro motor 8.

[0057] refer to Figure 2 and Figure 3 In a preferred embodiment, the cleaning unit includes: a second cleaning component 10, disposed on the second connecting shaft 9 and fixedly connected to the second connecting shaft 9; a second mounting plate 11, disposed inside the mounting shell 1 and fixedly connected to the mounting shell 1; and a second scraper 12, disposed on the second mounting plate 11 and fixedly connected to the second mounting plate 11.

[0058] In this configuration, the first scraper 7 and the second scraper 12 can respectively clean the surfaces of the developing roller 14 and the photosensitive drum 13; the first cleaning component 5 and the second cleaning component 10 can perform cleaning work when rotating; the first micro motor 3 and the second micro motor 8 are used to provide power and drive the first connecting shaft 4 and the second connecting shaft 9 to rotate respectively.

[0059] refer to Figure 2 and Figure 4 In a preferred embodiment, the developing mechanism includes: a developing unit disposed within the mounting housing 1 for developing operations; and a power unit disposed within the mounting housing 1 for providing power.

[0060] refer to Figure 2 In a preferred embodiment, the developing unit includes: a photosensitive drum 13, disposed within the mounting housing 1 and fixedly connected to the mounting housing 1; a developing roller 14, disposed within the mounting housing 1 and fixedly connected to the mounting housing 1; a charging roller 15, disposed within the mounting housing 1 and fixedly connected to the mounting housing 1; a waste toner chamber 20, disposed within the mounting housing 1 for storing waste toner; and a toner chamber 21, disposed within the mounting housing 1 for storing toner.

[0061] refer to Figure 4 In a preferred embodiment, the power unit includes: a first gear 16 disposed on the developing roller 14 and fixedly connected to the developing roller 14; a second gear 17 disposed on the photosensitive drum 13 and fixedly connected to the photosensitive drum 13; a drive motor 18 disposed on the first gear 16 and fixedly connected to the first gear 16; and a protective shell 19 disposed on the mounting shell 1 and fixedly connected to the mounting shell 1.

[0062] In this configuration, the first gear 16 and the second gear 17 can drive the developing roller 14 and the photosensitive drum 13 to rotate in opposite directions, and the charging roller 15 can charge and discharge the photosensitive drum 13 for imaging.

[0063] This device, by incorporating a developing mechanism, enables effective imaging during printing.

Furthermore, the device includes a cleaning mechanism that effectively cleans the developing roller 14 and photosensitive drum 13 during operation, ensuring long-term use and maintaining clear images.

[0064] Working principle: When this device is in use, the drive motor 18, the first micro motor 3, and the second micro motor 8 are started. The drive motor 18 can drive the first gear 16 to rotate clockwise, thereby causing the second gear 17 to rotate counterclockwise, which in turn causes the developing roller 14 and the photosensitive drum 13 to rotate. During rotation, the toner can be moved in an orderly manner onto the photosensitive drum 13 through the developing roller 14 for imaging. Simultaneously, when the drive motor 18 rotates, the first scraper 7 can leave excess toner on the developing roller 14 in the toner chamber 21, and the second scraper 12 can scrape off excess toner on the photosensitive drum 13 and put it into the waste toner chamber 20. At the same time, when the first micro motor 3 and the second micro motor 8 rotate, they respectively drive the first connecting shaft 4 and the second connecting shaft 9 to rotate. The first micro motor 3 rotates counterclockwise, and the second micro motor 8 rotates clockwise, causing the first connecting shaft 4 and the second connecting shaft 9 to drive the first cleaning component 5 and the second cleaning component 10 to rotate, cleaning the developing roller 14 and the photosensitive drum 13, ensuring that the developing roller 14 and the photosensitive drum 13 are clean, and ensuring that there are no impurities on the developing roller 14 and the photosensitive drum 13 when imaging is performed.
