Abstract
The utility model provides a cleaning scraping knife for removing carbon powder remained on the surface of a photosensitive drum in an imaging device. The cleaning scraping knife consists of a knife rest and two blades. The knife rest is fixed on the inner wall of a selenium drum waste powder storehouse; and the two blades are installed on two sides of the knife rest and are respectively contacted with the photosensitive drum installed on the selenium drum. The cleaning scraping knife cleans the carbon powder remained on the photosensitive drum and can prevent the surfaces of the cleaning scraping knife and the photosensitive drum from fast abrading, thus improving printing quality.
Description
Technical field
The utility model relates to toner cartridge cleaning doctor in a kind of electronic imaging device.
Background technology
Image processing systems such as duplicating machine, facsimile recorder, printer after the carbon dust image is transferred on the recording chart from photosensitive drums, still have carbon dust to remain in photosensitive drum surface, thereby need utilize cleaning doctor to remove residual carbon dust in print procedure.Typical cleaning doctor comprises knife rest and a slice blade, and blade only has a contact point with photosensitive drums, thereby totally needs cleaning doctor to apply bigger pressure at the contact point place to photosensitive drum surface residual carbon powder cleaning.Along with use, photosensitive drums produces surface abrasion under bigger pressure, causes the change of contact point place photosensitive drums physical and chemical state, reduces the stability of print quality; In the toner cartridge of high capacity high life used, above-mentioned bad phenomenon was more remarkable.
Summary of the invention
For achieving the above object, the utility model provides a kind of cleaning doctor that has two scrapers.
Technical scheme: cleaning doctor is made up of knife rest and two blades, and its intermediate slide is fixed on the toner cartridge waste powder hopper inwall; Two blades are divided into cutter and bottom knife, are installed in the both sides of knife rest respectively, and last bottom knife does not contact.
During operation, last bottom knife contacts with photosensitive drum surface respectively, thereby two contact points that form at photosensitive drum surface, and in cleaning course, photosensitive drums is along with the rotation of self can be subjected to cleaning twice.Therefore, cleaning doctor the contact point place to photosensitive drum surface apply less pressure both can carbon powder cleaning with photosensitive drum surface under.Material by adjusting the cutter bottom knife, length and and the contact area of photosensitive drum surface, can control the pressure that two blades are applied to the photosensitive drums surface of contact, reach best cleaning effect.
Because the remaining carbon dust of photosensitive drum surface can guarantee that through twice cleaning of cutter and bottom knife remaining carbon dust all cleans from photosensitive drum surface; Because the pressure that blade is applied on the photosensitive drums reduces, the wearing and tearing of cleaning doctor and photosensitive drum surface slow down greatly, and then have guaranteed the stability of print quality simultaneously.
Below in conjunction with the drawings and specific embodiments the utility model is introduced in detail.
Description of drawings
Fig. 1 is the structural representation of the utility model cleaning doctor
Fig. 2 is the structural representation that the utility model cleaning doctor cooperates with photosensitive drums
Cleaning doctor comprises knife rest 1 and the cutter 11 and the bottom knife 12 that are installed on the knife rest.
Knife rest 1 photosensitive drums 2 cutters 11 bottom knife 12 contact points 111
Another one contact point 121
As shown in Figure 2, cutter 11 is installed in a side of knife rest 1, and it is relative with cutter 11 with photosensitive drums 2 surface contact points 111 of formation, and bottom knife 12 is installed in another side of knife rest 1, and itself and photosensitive drums 2 surfaces form another one contact points 121.
Embodiment
In the toner cartridge course of work, the photosensitive drums 2 after transfer printing rotates to cleaning doctor 1 bottom knife 12 places, and cleaning doctor 12 cleans under the residual carbon pruinescence on the photosensitive drums 2, and along with photosensitive drums 2 is rotated further, 11 pairs of photosensitive drums of cutter clean once more.
Claims (3)
1. one kind remains in the cleaning doctor of carbon powder on photosensitive drum surface in order to removal, it is characterized in that this cleaning doctor is made up of a knife rest and two blades.
2. cleaning doctor according to claim 1 is characterized in that: two blades are installed in the both sides of knife rest respectively.
3. according to the described cleaning doctor of claim 1, it is characterized in that: do not contact mutually between described cutter and the described bottom knife.
