Description
Technical field
A kind of toner cartridge of novel photoactive drum of the present invention, is related to laser printer technical field more particularly to a kind of photosensitive drums.
Background technique
Most of in the toner cartridge of jump type developing in existing market is all to use magnetic roller as the accessory of intermediate transfer, by
It is aluminum pipe in the main body of magnetic roller, and photosensitive drum surface is accurate coating, will appear the variation of printing effect after abrasion, so sense
Light drum cannot directly be contacted with magnetic roller, avoid damage photosensitive drum surface coating.The prior art is that left magnetic roller both ends respectively install one
Circular ring shape sheath, photosensitive drums and magnetic roller are separated, and control the distance between photosensitive drums and magnetic roller by changing the thickness of sheath, from
And change the blackness of printing.Sheath is that needs are separately installed at present, increases operational sequence, existing structure is due to magnetic roller surface
There is carbon dust always, after printing after a period of time, has part and enter between sheath and magnetic roller, make between photosensitive drums and magnetic roller
Distance increases, and causes to print blackness reduction or jump white.
Summary of the invention
In view of the above shortcomings of the prior art, the present invention provides a kind of toner cartridge of novel photoactive drum, can improve production efficiency
And will not cause sheath enter foreign matter cause influence print quality.
To achieve the goals above, the technical scheme adopted by the invention is that: a kind of toner cartridge of novel photoactive drum, comprising useless
Powder cabin, charging roller, photosensitive drums, goes out powder scraper, powder cabin, magnetic roller and carbon dust at cleaning doctor.The waste powder hopper is that the storage of toner cartridge is useless
The shell mechanism of powder, is made of plastic cement；The cleaning doctor is mounted on the surface in waste powder hopper inside groove；The charging roller installation
In the charging roller support of the top of cleaning doctor, photosensitive drums are installed in parallel in the side of charging roller with charging roller, with charging roller
Intimate surface contact, and it is tangent with the rubber strip edges of cleaning doctor；The powder cabin is the shell mechanism of the storage carbon dust of toner cartridge, by
Plastic cement is made；The powder cabin is equipped with inner cavity, and carbon dust fills in the lumen, and powder scraper is installed on the side of powder cabin meal outlet, magnetic roller out
The top of the meal outlet of installation, it is tangent with powder scraper cutting edge out.The photoreceptor drum contains sensitizing tube, conducting end rubber head and gear end
Rubber head；The sensitizing tube is the round aluminum pipe for being coated with photosensitive material；The gear end rubber head is by sliding tooth and gear end connector
The integral structure of composition, for sliding tooth on the gear end connector left side, gear end connector is the concentric double-deck circular tube structure, interior
The outer diameter of layer is equal to the internal diameter of sensitizing tube, and it is thick for the outer diameter of sensitizing tube and required sheath that gear end connects the outer diameter of volume surrounding
The sum of two multiple values of degree；The conducting end rubber head is made of conductive metal sheet and conducting end connector, and conducting end connector is
The concentric double-deck circular tube structure, axis line position have a through-hole, and the outer diameter of conducting end connector internal layer is equal to sensitizing tube
Internal diameter, the outer diameter that conducting end connects volume surrounding is the outer diameter of sensitizing tube and the sum of two multiple values of required jacket thickness, conducting end
It is symmetrical with intermediate throughholes on end face on the inside of connector to set there are two detent, conductive metal sheet is elongated metal piece, and both ends are
The protrusion of point, the distance of both ends protrusion are greater than the internal diameter of sensitizing tube, and centre is more logical than among conducting end connector internal layer equipped with one
The big circular hole in hole, circular hole is interior to be equipped with the two opposite conductive sheets stretched out from both ends to center of circular hole, and conductive metal sheet correspondence is led
Location hole there are two setting at detent on electric end connector, can make conductive metal sheet be fixed on conducting end connector after being caught in detent
End face on；The connector internal layer of gear end rubber head and conducting end rubber head is inserted into the both ends of sensitizing tube respectively, and in sensitizing tube
Inside gluing is fixed, and sensitizing tube both ends are withstood on the outer layer end face of connector.
When the toner cartridge is installed, since the both ends rubber head of photosensitive drums is equipped with connector layer structure, magnetic roller both ends do not have to
Sheath is installed, reduces process, and since connector is structure as a whole, it is seamless between connector internal layer and outer layer, it will not go out
Enter in existing sheath and prints abnormal phenomenon produced by the foreign matters such as carbon dust.
A kind of beneficial effect of the toner cartridge of novel photoactive drum of the present invention is: 1, working hour is saved, cost is reduced.2, in sheath not
The foreign matters such as carbon dust can be entered and cause printing abnormal.
