A toner cartridge with a new worm positioning structure at the gear end of the powder bin

Abstract

The invention provides a toner cartridge with a novel toner cabin gear end stirring frame positioning structure. The toner cartridge comprises a toner cartridge body which is internally provided with a toner cabin; feeding worms are supported on two side walls of the toner cabin; one end of each worm stretches out of the gear end of the toner cabin; positioning clamping positions protruding outwards from the surface of the toner cabin are arranged in the positions with the end parts of the worms at the gear end of the toner cabin and are internally provided with sealing rings; through holes, through which the end parts of the worms penetrate, are formed in the surfaces of the positioning clamping positions. As the positioning clamping positions protruding outwards from the toner cabin body are arranged at the gear end of the toner cabin, a conventional worm shaft sleeve is replaced, the assembling process of the toner cartridge is reduced, and moreover, materials are reduced; the sealing rings are arranged into the positioning clamping positions from the interior of the toner cabin, the toner cabin is good in sealing capability as the gaps between the sealing rings and the positioning clamping positions are small, and therefore the reliability of the toner cartridge is improved.

Description

technical field [0001] The invention relates to the technical field of printer consumables, in particular to a toner cartridge with a novel worm positioning structure at the gear end of a powder bin. Background technique [0002] At present, the original laser printer toner cartridges of various brands and models that are commonly used in the market include the toner cartridge body, and the toner cartridge body is provided with a powder bin, which is equipped with a toner for stirring the toner in the powder bin. Send to the stirrer in the developer. The two ends of the stirring frame are respectively arranged in a rotatable manner on opposite side walls of the powder bin. In addition, a driving gear for driving the stirring frame to rotate is provided on the outer surface of the powder bin corresponding to one end of the stirring frame, and the driving gear meshes with the gear in the developing device. The end of the powder bin provided with the drive gear is the so-call...

Problems solved by technology

[0004] The disadvantage of the above method is that the worm shaft sleeve needs to be used, the assembly cost is high, and the material cost is high. Moreover, since the shaft sleeve and the sealing ring are all installed later, the shaft sleeve, sealing ring, and the end of the worm are all independent parts. All rely on assembly to complete the combination, which is likely to cause poor sealing effect, resulting in powder leakage
