Problems solved by technology

The structure of the traditional toner cartridge is relatively complicated, the production cost is high, the transmission stability is not good, the assembly operation is inconvenient, and the powder addition is not convenient enough; the drum core is connected and energized by the central shaft penetration method, which requires a large amount of material and increases the weight; the conductive frame connection is easy to fall out. The power supply of the drum core and the charging roller is unstable, and it is prone to problems such as pollution before use

Abstract

Disclosed is a toner cartridge which comprises a powder bin, a waste powder bin, a cartridge core, a charging roller, a developing roller, a powder feeding roller, a power stirring roller and a transmission mechanism. The transmission mechanism comprises a cartridge core gear, a developing roller gear, a multi-meshing gear, a powder feeding roller gear, a transmission wheel and a powder stirrer gear, the multi-meshing gear is meshed with the powder feeding roller gear, the transmission wheel and the developing roller gear respectively, the transmission wheel is meshed with the powder stirrer gear, and the cartridge core gear is meshed with the developing roller gear. The toner cartridge has the advantages of being highly stable in transmission, simple in structure, easy to assemble and disassemble, cost-effective, easy in powder adding and waste powder cleaning and capable of effectively improving printing quality.

Description

【Technical field】 [0001] The invention relates to a toner cartridge used in a laser printer. 【Background technique】 [0002] Laser printers are widely used at present, and toner cartridges are the main components of laser printers. The main core components of the toner cartridge include: toner bin, waste toner bin, photosensitive drum, charging roller, developing device and cleaning blade, etc. The structure of the traditional toner cartridge is relatively complicated, the production cost is high, the transmission stability is not good, the assembly operation is inconvenient, and the powder addition is not convenient enough; the drum core is connected and energized by the central shaft penetration method, which requires a large amount of material and increases the weight; the conductive frame connection is easy to fall out. The power supply of the drum core and the charging roller is unstable, and it is prone to problems such as pollution before use. [0003] In order to o...
