Abstract
A kind of toner cartridge for preventing cleaning doctor overturning, is related to a kind of laser printer technical field, comprising powder cabin, waste powder hopper, photosensitive drums, charging roller, cleaning doctor, goes out powder scraper, magnetic roller and cleaning blade.It is described go out powder scraper, magnetic roller and carbon dust are mounted in powder cabin, the photosensitive drums, charging roller, cleaning doctor and cleaning blade are mounted on waste powder hopper, waste powder hopper and powder cabin are combined into a toner cartridge, the cleaning blade shape is U-shaped, cleaning blade is parallel with cleaning doctor and is linearly mounted on waste powder hopper glue part, photosensitive drums are tangent with cleaning doctor and cleaning blade respectively, cleaning blade both ends angled portion is ridden on the cutting edge of cleaning doctor, so that the cutting edge at cleaning doctor both ends is not contacted with photosensitive drums, when photosensitive drums rotate, even if there is the inadequate situation of lubricity between the two, the phenomenon that overturning will not occur in cleaning doctor.
Description
Technical field
A kind of toner cartridge for preventing cleaning doctor overturning, is related to a kind of laser printer technical field more particularly to one kind is pre-
The toner cartridge of anti-cleaning doctor overturning.
Background technology
The toner cartridge of general printer by powder cabin, waste powder hopper, photosensitive drums, charging roller, magnetic roller or developer roll, go out powder scraper and clear
The major parts such as clean scraper form, and a combination thereof forms a toner cartridge together, mounted on the inside of printer, for developing to
Picture.Wherein, photosensitive drums, charging roller and cleaning doctor are mounted in waste powder hopper plastic housing, and cleaning doctor and photosensitive drum surface simultaneously have
Certain pressure is scraped in waste powder hopper by cleaning doctor when photosensitive drums carry the carbon dust rotation for remaining in surface, is scraped with cleaning
The relatively parallel position of knife is flown out there are one bar shaped non-return piece, that is, waste powder hopper scraping blade with the powder that prevents from giving up after cleaning, is shown in toner cartridge
In shadow imaging process, if the cutting edge lubricity of cleaning doctor left and right ends may result in cleaning doctor overturning situations such as inadequate,
There is the defects of printer paperboard, abnormal sound, leakage powder and printing black, make toner cartridge that can not be continuing with.
Invention content
The purpose of the present invention is to solve the above problems, propose a kind of toner cartridge for preventing cleaning doctor overturning.
The technical scheme is that：It is a kind of prevent cleaning doctor overturning toner cartridge, comprising powder cabin, waste powder hopper, photosensitive drums,
Charging roller, cleaning doctor go out powder scraper, magnetic roller and cleaning blade.It is described go out powder scraper, magnetic roller and carbon dust be mounted on powder cabin on,
The photosensitive drums, charging roller, cleaning doctor and cleaning blade are mounted on waste powder hopper, and waste powder hopper and powder cabin are combined into a selenium
Drum.The cleaning blade shape is U-shaped, and cleaning blade is parallel with cleaning doctor and is linearly mounted on waste powder hopper glue part, sense
Light drum is tangent with cleaning doctor and cleaning blade respectively, and cleaning blade both ends angled portion is ridden on cleaning doctor so that cleaning
The cutting edge at scraper both ends is not contacted with photosensitive drums, when photosensitive drums rotate, even if there is the inadequate situation of lubricity between the two,
The phenomenon that overturning will not occur in cleaning doctor.
Preferably, in order to not influence the recycling of useless powder under the premise of the lubricity between photosensitive drums and cleaning doctor is increased
Rate, the angled portion at cleaning blade both ends and the interface width of cleaning doctor be 1 ~ 3mm, the gold of of length no more than cleaning doctor
Belong to pedestal.
The advantageous effect of toner cartridge that the present invention is a kind of to prevent cleaning doctor overturning is：Avoid sword of the toner cartridge due to cleaning doctor
Mouth lubricity not enough causes cleaning doctor to overturn, and reduces customer complaint rate.
Description of the drawings
Attached drawing 1 is a kind of toner cartridge schematic diagram for the toner cartridge for preventing cleaning doctor overturning of the present invention, and attached drawing 2 is of the invention a kind of
Prevent the waste powder hopper part accessory schematic diagram of the toner cartridge of cleaning doctor overturning, attached drawing 3 is that a kind of prevention cleaning doctor of the present invention turns over
The assembling schematic diagram of cleaning doctor and cleaning blade in the toner cartridge turned, attached drawing 4 are that a kind of prevention cleaning doctor of the present invention is overturn
The close-up schematic view of cleaning doctor and cleaning blade in toner cartridge.In figure：1 is waste powder hopper, and 2 be cleaning doctor, and 3 be charging
Roller, 4 be photosensitive drums, and 5 be powder scraper, and 6 be powder cabin, and 7 be magnetic roller, and 8 be carbon dust, and 9 be cleaning blade, and 91 roll over for cleaning blade
Angle.
Specific embodiment
The present invention is illustrated below in conjunction with the accompanying drawings：With reference to attached drawing 1, Fig. 2, Fig. 3 and Fig. 4, a kind of prevention of the present invention
A kind of toner cartridge of wear-resisting type of the toner cartridge present invention of cleaning doctor overturning includes waste powder hopper 1, cleaning doctor 2, charging roller 3, photosensitive drums
4th, go out powder scraper 5, powder cabin 6, magnetic roller 7, carbon dust 8 and cleaning blade 9.It is described go out powder scraper 5, magnetic roller 7 and carbon dust 8 be mounted on powder cabin
On 6, the photosensitive drums 4, charging roller 3, cleaning doctor 2 and cleaning blade 9 are mounted on waste powder hopper 1,6 groups of waste powder hopper 1 and powder cabin
Synthesize a toner cartridge.
The implementation method of toner cartridge that the present invention is a kind of to prevent cleaning doctor overturning is：Cleaning blade 9 is parallel with cleaning doctor 2
And straight line is mounted on waste powder hopper 1, and photosensitive drums 4 are tangent with cleaning doctor 2 and cleaning blade 9 respectively, 9 both ends of cleaning blade
Cleaning blade dog-ear 91 can cover the cutting edge at 2 both ends of cleaning doctor, increase the lubricity between photosensitive drums 4 and cleaning doctor 2
While, in order to not influence the rate of recovery of useless powder, the interface width that cleaning blade dog-ear 91 rides over cleaning doctor 2 is 1 ~ 3mm,
The metal pedestal of of length no more than cleaning doctor 2 so that the cutting edge at 2 both ends of cleaning doctor is not contacted with photosensitive drums 4, works as photosensitive drums
During 4 rotation, even if there is the inadequate situation of lubricity between the two, the phenomenon that overturning will not occur in cleaning doctor 2, prevent
It is abnormal, achieve the purpose that reduce customer complaint rate.
