Abstract
The utility model discloses an even selenium drum structure of developing, it is including roller, sensitization drum, developer roll and the end cover of charging, charge the both ends of roller, sensitization drum and developer roll and all be connected with the end cover rotation, charge the surface of roller and support to press at the sensitization drum on the surface, the surface of sensitization drum and the surperficial contactless of developer roll. The utility model discloses a messenger charges the surface of roller and support to press at the sensitization drum on the surface, extrusion friction bulging by sensitization and that charge between the rod drives the rod rotation of charging, the rotation that the messenger charges the roller becomes the driven form that sensitization was roused, and make the surface of sensitization drum and the surface of developer roll be non -contact, through voltage control conveying carbon dust, thereby the homogeneity that the carbon dust develops has been improved, the disposable who has not only guaranteed print quality and carbon dust is rateed, and the life of sensitization drum and printer has been prolonged.
Description
Technical field
This utility model relates to a kind of toner cartridge, specifically, relates to a kind of uniform toner cartridge structure of developing, belongs to printer and join
Part technical field.
Background technology
The advantage that laser printer is fast with its print speed, print quality is high, is widely used in the field such as commercial affairs, office.Selenium
Drum is laser printer core parts requisite, extremely important, is the important consumptive material of printer.Laser printer
Toner cartridge is typically to be made up of, because at laser components such as photosensitive drums, charging roller, developer roll, powder feeder unit and plastic casings
In printer, the image-forming block of more than 70% concentrates in toner cartridge, and therefore, laser printer is beaten by the structure design of toner cartridge
Print quality plays decisive role.But current toner cartridge structure has following defects that
1, charging roller and photosensitive drums are driven by gear respectively and rotate at a same speed, carry out photosensitive drums realizing charging roller
On-line treatment, so that under higher rotation speed, charging roller is very big with the surface pressing of photosensitive drums, easily makes photosensitive drum surface send out
Raw abrasion, not only can shorten the service life of photosensitive drums and printer, and carbon dust development can be caused the most uneven, thus
Affect the single use rate of print quality and carbon dust, so that use cost is the highest and the wasting of resources；
2, developer roll and photosensitive drums design bonded to each other, long-term friction between the two can cause carbon dust development the most uneven,
Thus affect the single use rate of print quality and carbon dust.
Utility model content
The problems referred to above existed for prior art, the purpose of this utility model is to provide a kind of uniform toner cartridge structure of developing.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of uniform toner cartridge structure of developing, including charging roller, photosensitive drums, developer roll and end cap, described charging roller, photosensitive
The two ends of drum and developer roll are all rotationally connected with end cap, it is characterised in that: the surface of described charging roller is pressed on the table of photosensitive drums
On face, the surface of described photosensitive drums does not contacts with the surface of developer roll.
Preferably, one end of described photosensitive drums is provided with gear, and described gear is connected with motor.
Preferably, the gap between surface and the surface of developer roll of photosensitive drums is 0.15～0.25 millimeter.
Preferably, described toner cartridge also includes that agitating roller, the cross section of described agitating roller are zigzag.
Compared to prior art, Advantageous Effects of the present utility model is:
This utility model is by making the surface of charging roller be pressed on the surface of photosensitive drums, by squeezing between photosensitive drums and charging rod
Pressure friction drives charging rod to rotate, and makes the rotation of charging roller become the driven form of photosensitive drums, thus realizes charging roller to photosensitive
The on-line treatment of drum；Further, this utility model makes the surface of photosensitive drums be contactless with the surface of developer roll, passes through voltage
Control to transmit carbon dust, thus improve the uniformity of carbon dust development, not only ensure that the single use of print quality and carbon dust
Rate, and extend the service life of photosensitive drums and printer, there is practical value.
Accompanying drawing explanation
Fig. 1 is the explosive view of a kind of uniform toner cartridge structure of developing that this utility model provides；
Fig. 2 is the partial sectional view of a kind of uniform toner cartridge structure of developing that this utility model provides.
In figure, label is schematically as follows: 1-charging roller；2-photosensitive drums；3-developer roll；4, end cap；5-agitating roller；6-gear.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.
Shown in Fig. 1 and Fig. 2: the one uniform toner cartridge structure of development that this utility model provides, including charging roller 1, sense
Light drum 2, developer roll 3 and end cap 4, the two ends of described charging roller 1, photosensitive drums 2 and developer roll 3 all rotate even with end cap 4
Connecing, the surface of described charging roller 1 is pressed on the surface of photosensitive drums 2, the surface of described photosensitive drums 2 and the table of developer roll 3
Face does not contacts.
Preferably:
One end of described photosensitive drums 2 is provided with gear 6, and described gear 6 is connected with motor (not shown).
Gap between surface and the surface of developer roll 3 of photosensitive drums 2 is 0.15～0.25 millimeter.
Described toner cartridge also includes agitating roller 5, and the cross section of described agitating roller 5 is zigzag.
By making the surface of charging roller 1 be pressed on the surface of photosensitive drums 2, by the rotation of photosensitive drums 2, drive charging rod 1
Rotate, make the rotation of charging roller 1 become the driven form of photosensitive drums 2 rather than drive separately through gear, thus can protect
Pressure between card charging roller 1 and photosensitive drums 2 is constant, can effectively prevent charging roller 1 from producing scar with the surface of photosensitive drums 2,
Avoid therefore producing carbon dust development problem of non-uniform；Further, this utility model makes the surface of photosensitive drums 2 and the table of developer roll 3
Face is contactless, has certain interval, and carbon dust is transmitted by the voltage applied, such that it is able to avoid carbon dust due to extruding
And it is bonded at the surface of photosensitive drums 2 and the surface of developer roll 3, prevent photosensitive drums 2 and developer roll 3 surface abrasion, thus also may be used
Improve the uniformity of carbon dust development；This utility model not only can ensure the single use rate of print quality and carbon dust, Er Qieke
Extend photosensitive drums and the service life of printer, there is practical value.
Finally be necessary it is pointed out here that: the foregoing is only this utility model preferably detailed description of the invention, but this practicality
Novel protection domain is not limited thereto, the technology that any those familiar with the art discloses at this utility model
In the range of, the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.
