Description

Technical Field

[0001] This utility model relates to the field of sealed toner cartridge technology, and more specifically, to a modular toner cartridge with a sealed toner compartment. Background Technology

[0002] Highly sealed toner cartridges significantly improve printing stability, reduce toner leakage, moisture, and waste toner accumulation, thereby extending printer life and ensuring output quality. The toner cartridge in a laser printer is a core imaging component, and its sealing performance directly affects print quality and equipment health. Poor sealing can lead to toner leakage, moisture-induced clumping, or damage to the photosensitive drum, resulting in blurry prints, severe background graying, paper jams, or even damage to internal machine components. Currently, mainstream toner cartridge sealing methods mainly include removable seals, flexible sealing plates, and automatic opening and closing toner baffles, designed to prevent toner leakage during transportation and storage, and to reliably open during use to ensure normal printing.

[0003] Most existing plug-in type toner cartridges have a separate toner-blocking structure. During use, the toner cartridge is loaded and moved to facilitate magnetic toner discharge. The toner cartridge and other components are mostly spliced ​​or plugged in. In normal use, the waste toner cartridge and drum core are assembled together for printing. During disassembly, maintenance and reuse, the separate toner-blocking structure is not very effective in blocking and protecting the waste toner cartridge and drum core, requiring additional protection, which reduces the overall efficiency and effectiveness of loading, unloading and maintenance.

[0004] In summary, in order to address the issue of the weak protective effect of a separate toner-blocking structure on the drum core and waste toner compartment during the loading, unloading, reuse, and maintenance of modular toner cartridges with sealed toner compartments, it is necessary to ensure the overall toner blocking effect and improve the protection capability of modular toner cartridges with sealed toner compartments during assembly and separation. Utility Model Content

[0005] The problem to be solved by the modular toner cartridge sealing drum provided by this utility model is that: when using the existing modular toner cartridge sealing drum, the waste toner cartridge and drum core are assembled together for printing. During disassembly, maintenance and reuse, the individual toner blocking structure has a weak effect on blocking and protecting the toner of the waste toner cartridge and drum core as a whole, which reduces the overall loading, unloading and maintenance efficiency and effectiveness.
