Abstract

The invention relates to the technical field of laser printers, in particular to a combined toner cartridge capable of circularly replacing a toner cartridge, and solves the problems of defects caused by directly pouring powder into a toner supply bin and high replacement and maintenance cost of the toner cartridge in the prior art. The invention relates to a combined selenium drum capable of circularly replacing a powder box, which comprises a powder cabin, a photosensitive drum, a developing roller and a transfer printing roller, and further comprises a shell which is of a box-shaped structure. According to the toner cartridge capable of circularly replacing the toner cartridge, the screw rod is rotated, the movement that the nut seat inwards pushes or outwards pulls the toner cartridge is realized by utilizing the screw rod movement of the screw rod and the nut seat, and then the clamping connection between the traction rod and the fixed block on the nut seat is released, so that the toner cartridge capable of circularly replacing the toner cartridge is realized; compared with the prior art, the powder box is more convenient and stable, damage caused by powder flying is reduced, meanwhile, the accuracy of positioning installation of the powder box is achieved through movement of the lead screw, and positioning between the discharging port of the powder box and the discharging port of the powder bin is more accurate.

Description

technical field [0001] The invention relates to the technical field of laser printers, in particular to a combined toner cartridge which can replace a toner cartridge in a cycle. Background technique [0002] The toner cartridge of a general printer is composed of main parts such as a toner supply bin, a waste toner bin, a photosensitive drum, a charging roller, a magnetic roller or a developing roller, a powder discharge scraper, and a cleaning scraper, which are combined to form a toner cartridge, which is installed inside the printer. For developing imaging. Among them, the powder knife, magnetic roller or developing roller are installed on the plastic part of the powder supply bin, the photosensitive drum, charging roller and cleaning blade are installed in the plastic shell of the waste toner bin, and the charging roller contacts the surface of the photosensitive drum to charge the photosensitive drum. [0003] The existing toner cartridges still have the following def...
