Abstract
The utility model discloses a kind of toner cartridges to eliminate smear structure, the utility model is equipped with the cavernous elastomer that can be contacted with developing roller surface magnetic carbon powder in handle box, to remaining magnetic carbon powder and elastomer contact after a developing process, being swept by the extruding of elastomer makes the remaining magnetic carbon powder of developing roller surface be evenly distributed, to can also uniformly fill new magnetic carbon powder in developing roller surface subsequent, so that being unevenly distributed for new powder will not be formed in developing roller surface, thus the problem of also eliminate smear.
Description
Technical field
The utility model relates to a kind of laser printer, especially a kind of toner cartridge eliminates smear structure.
Background technique
The present apparatus is contact type developing, this development roll structure includes the magnetic core of aluminum pipe and centre and the rubber of outer layer, development
Roller and photosensitive drums contact and being greater than magnetic field force by electric field force makes carbon dust be adsorbed on electrostatic latent image area, and carbon dust is magnetic carbon
Powder, and by charge in blade strip before imaging, because developer roll can adsorb carbon dust and dally, and in the process can when starting
It is repeatedly rubbed by scraper, thus carbon dust carried charge is high.It but is not all on developer roll during participating in development
The carbon dust participation of being all adsorbed over is developed, and only the carbon dust with electrostatic latent image area corresponding region (abbreviation a-quadrant) can be drawn onto
Development is participated in photosensitive drums, developer roll, which turns to, after the completion of development mends powder in powder cabin, because only that the carbon dust of a-quadrant reduces,
Thus a-quadrant can fill new carbon dust, and using charge in blade strip, but the carbon dust usually newly mended is compared to remaining powder institute band
Electricity wants low.If that the electrostatic latent image area of development next time corresponding region on developer roll is the region C, and the region C is by a-quadrant
(and the additional voltage in electrostatic latent image area is all identical) is constituted with B area, but is adsorbed to electrostatic latent image area corresponding A region
The density of carbon dust is different from the density of carbon dust for being adsorbed to the corresponding B area in electrostatic latent image area, thus on printing paper a-quadrant and
B area will form two kinds of different figures of shade, make it is desirable that indistinctly occurring a-quadrant in obtained C regional graphics again
Figure, (if normal, be adsorbed to the density of the carbon dust in electrostatic latent image area corresponding A region and to be adsorbed to electrostatic latent
As density that area corresponds to the carbon dust of B area be it is identical, thus a-quadrant and B area be correspondingly formed figure color be it is identical,
A-quadrant and B area are correspondingly formed the C regional graphics that figure is an entirety) because shade is different causing at this
The image (i.e. smear) of last development is indistinctly shown on the image of development, thus causes printing effect very poor.
Certainly, when above situation not merely occurs from starting up, during subsequent printing sometimes
It will appear the above problem, thus we need to design the new structure of one kind to eliminate the above problem, to guarantee print quality.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of toner cartridge elimination smear structure.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of toner cartridge eliminates smear structure, including be set in handle box powder cabin, developer roll, it is characterised in that: it is described
The cavernous elastomer that the magnetic carbon powder that being equipped in handle box can adsorb with developing roller surface contacts, and in each development
In period, the remaining magnetic carbon powder that developing roller surface adsorbs after the completion of developer roll development is transferred to again after elastomer is swept
Powder cabin.
The cavernous elastomer shape is rectangular strip.
The cavernous elastomer is sponge roller made of sponge.
The powder cabin side wall and developer roll have gap, and the elastomer is located at the gap location, and closes the gap.
The elastomer is adhered on powder cabin wall.
The beneficial effects of the utility model are: the utility model in handle box be equipped with can be with developing roller surface magnetic carbon
The cavernous elastomer of powder contact, so that remaining magnetic carbon powder and elastomer contact after a developing process, lead to
The extruding for crossing elastomer, which is swept, makes the remaining magnetic carbon powder of developing roller surface be evenly distributed, thus it is subsequent can also be in developer roll
New magnetic carbon powder is uniformly filled on surface, so that being unevenly distributed for new powder will not be formed in developing roller surface, thus is also eliminated
The problem of smear.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Referring to Fig.1, the utility model discloses a kind of toner cartridges to eliminate smear structure, including the powder cabin being set in handle box
1, developer roll 2 and photosensitive drums 3, above-mentioned principle and structure are the prior arts, thus are not described in detail, be equipped in handle box can with it is aobvious
The cavernous elastomer 5 that the magnetic carbon powder 4 of 2 adsorption of shadow roller contacts, the preferred sponge of elastomer 5, the preferred strip of shape
It is rectangular, be not only convenient for cutting, be also convenient for being bonded, be fixed on by the way of bonding on 1 wall of powder cabin, the material of certain elastomer 5
Material and shape can also be other, the above-mentioned description for being only applied particularly to this example.
The installation site of elastomer 5 preferably has gap location in 1 side wall of powder cabin and developer roll 2, and certainly, elastomer 5 can also
Other positions in handle box, as long as in each development cycle, the residue of adsorption after the completion of developer roll development
Magnetic carbon powder can be swept by elastomer after be transferred to powder cabin again.The elastomer 5 is located at the gap location, and closes
The gap.Envelope arogel item is equipped with before the gap, for preventing magnetic carbon powder 4 from leaking out from the gap location, we cancel now
Envelope arogel item, and with elastomer 5, can not only play the function of envelope powder in this way, also have to squeeze and sweep 2 surface carbon of developer roll
The effect of powder, and sealing effect is more preferable, thus sealing arogel item is contact or contact with 2 surface carbon dust of developer roll and very
Slight, thus some distances are always had between the two.And above-mentioned change takes full advantage of the structure of printer itself, not additionally
Occupied space, repacking are more convenient.
Smear structure is eliminated to a kind of toner cartridge provided by the utility model embodiment above, is described in detail, this
It applies specific case in text to be expounded the principles of the present invention and embodiment, the explanation of above embodiments is
It is used to help understand the method and its core concept of the utility model；At the same time, for those skilled in the art, according to this
The thought of utility model, there will be changes in the specific implementation manner and application range, in conclusion the content of the present specification
It should not be construed as a limitation of the present invention.
