Driving gear structure of double-layer toner cartridge

Abstract

The invention relates to a driving gear structure of a double-layer toner cartridge. The driving gear structure comprises a main driving gear and a develop roller driving gear which are arranged on an outer layer, and are meshed with each other, and a stirring gear and a powder feeding roller driving gear which are arranged on the inner layer; the main driving gear, the stirring gear, and the powder feeding roller driving gear are connected successively via drive connection. The driving gear structure is invented based on a novel driving method and driving principles; at least parts of the driving gears of the outer layer and the inner layer are overlapped in the longitudianl direction; occupied area is small; structure is compact and skilful; modification of magnetic toner cartridges into non-magnetic toner cartridges is realized; the non-magnetic toner cartridges can be used in original magnetic toner cartridge printers; user application cost is reduced; the monopoly of original manufacturers is broken; it is beneficial for development of manufacturers of non-magnetic toner cartridges and regenerated toner cartridges; industry development is promoted; nonsynchronous initiation of the powder feeding roller and the develop roller is realized; the surface of the develop roller is washed before running of the toner cartridge; and toner cartridge printing quality is increased.

Description

technical field [0001] The invention belongs to the technical field of toner cartridges, in particular to a driving tooth structure of a double-layer toner cartridge. Background technique [0002] At present, the original manufacturers on the market will design and produce specially matched magnetic toner cartridge printers for their magnetic toner cartridge printers, and in order to achieve the purpose of only using magnetic toner cartridges and not non-magnetic toner cartridges, they will design the size of the magnetic toner cartridges to be relatively small At the same time, the size of the printer’s landing position is also designed to match the size of the magnetic toner cartridge (due to the large size of the shell at the powder feeding port of the non-magnetic toner cartridge, it cannot be installed on the original magnetic toner cartridge printer), so it is very The market competitiveness of magnetic toner cartridges is extremely limited, and because the price of ma...

[0002] At present, the original manufacturers on the market will design and produce specially matched magnetic toner cartridge printers for their magnetic toner cartridge printers, and in order to achieve the purpose of only using magnetic toner cartridges and not non-magnetic toner cartridges, they will design the size of the magnetic toner cartridges to be relatively small At the same time, the size of the printer’s landing position is also designed to match the size of the magnetic toner cartridge (due to the large size of the shell at the powder feeding port of the non-magnetic toner cartridge, it cannot be installed on the original magnetic toner cartridge printer), so it is very The market competitiveness of magnetic toner cartridges is extremely limited, and because the price of magnetic toner is much higher than that of non-magnetic toner, users need to pay more for long-term use

[0003] In addition, the driving teeth of the developing roller and the driving teeth of the powder feeding roller of the non-magnetic toner cartridges currently on the market are directly meshed with the main driving teeth and started synchronously. With powder feeding function, single function
