The utility model content
The purpose of this utility model is by using a kind of working stability, thereby long useless powder scraper plate of life-span guarantees toner cartridge can not occur can not occurring between useless powder scraper plate and the bulging core the wafing phenomenon of powder, dusting, effectively reduce the number of times that toner cartridge needs repairing, provide a kind of maintenance man-hours few printer toner cartridge.
The toner cartridge scraper plate directly affects the print quality of printer as a vitals in the selenium drum of laser printer, the effect of scraper plate is, scraper plate and drum cooperatively interact between the core and will not be transferred roller transfer to the powder collecting bin that advances to give up of the carbon dust clearing on the paper on the drum core, so that drum core drum wicking surface when charging does not have carbon dust to disturb next time, if the useless powder of not removing on the clean drum core can print off vertical underworld on paper so when the drum core forwards next circle to, thereby the quality that impact is printed.
The realization the technical solution of the utility model is: a kind of toner cartridge is comprised of drum core, toner, useless powder collecting bin, selenium drum chip, developer roll, transfer roll, useless powder scraper plate and selenium drum shell, described useless powder scraper plate both sides are provided with the gap that mass screw is used for fixing bulging core and useless powder scraper plate, the utility model is characterised in that increasing on the useless powder scraper plate has useless powder squeegee fixation device.
Described useless powder squeegee fixation device is for arranging 1-3 mass screw at useless powder scraper plate middle part.Mass screw is good has fixed gap between useless powder scraper plate and the drum core, even still can guarantee later on that at long print job the gap between useless powder scraper plate and the drum core remains on a preferably state, thereby improved the quality of toner cartridge, increase the toner cartridge life-span, reduced more maintenance frequency.
The beneficial effects of the utility model are: toner cartridge is through after the long print job, gap between useless powder scraper plate and the drum core can remain on a better distance, the waft phenomenon of powder, dusting of useless powder scraper plate central region can not appear, effectively reduce the number of times that toner cartridge needs repairing, provide a kind of maintenance man-hours few printer toner cartridge.
