Description
Technical field
The utility model relates to printer accessory technical fields, and in particular to a kind of useless powder cycling and reutilization scraper of toner cartridge.
Background technique
Contact developing toner cartridge currently on the market is used for laser printer, and the course of work of laser printing, which can be divided into, fills
Electricity, exposure, transfer, fixing, 7 cleaning, electric eliminating steps, wherein five steps are carried out around toner cartridge.Firstly, by charging roller
One layer of negative electrical charge is filled on photosensitive drums surface layer.After photosensitive drums are electrically charged, when laser beam shines photosensitive drums surface layer, irradiated area
On charge disappear, the charge on non-irradiated area remains unchanged, in this way, the potential difference of exposure area and unexposed area was both
Form one layer of electrostatic latent image.On the other hand, from powder cabin come out carbon dust be electrically charged after powder feeding roller generate elecrtonegativity.Magnetic roller is more
For metal core rubber roller, there is very big resistance, when imposing voltage to it, the charged toner in powder feeding roller will be transferred to relative potentials
Come in high magnetic roller.Powder outlet cutter and magnetic roller keep minimum gap, and the voltage that it is also subjected to an alternation is same, can be continuous
Concussion in make carbon dust activate and very thin one layer that its Gua Cheng Zhuo is even, next, when negatively charged carbon dust with photosensitive
When drum is gone near printing paper, under the action of the transfer roll filled with positive electricity, negatively charged carbon dust is attracted to the surface of paper
It is upper.It in fixing member, using the method for pressurization hot melt, is immersed in the carbon dust of fusing in printing paper, forms fixed image.
Next, the useless powder that cleaning doctor does not completely shift photosensitive drum surface blows into waste powder hopper, next printing interval is made to have one
A clean photosensitive drums.However in practical work process, due to cleaning doctor long-time service aging also or photosensitive drum surface
It speckles with other impurities and is not easy to remove completely, photosensitive drums in next printing interval is caused to be beaten as caused by not clean
It misprints mistake, the problems such as printing quality is poor.And the useless powder for blowing into waste powder hopper is unable to recycling and reusing, causes the waste of resource and beats
It is printed as this raising.
Summary of the invention

Slot is connect by pasting reinforced hole with film；The scraper mounting plate close to scrape bit end be equipped with connect powder plate mounting hole.
Further, second scraper includes scraper mounting plate, scraping blade, indent, pastes reinforced hole and film, wherein scraping
Knife mounting plate is of an L-shaped structure, and the scraper mounting plate is connect with scraping blade one-way movable；The scraping blade is connect with indent；The pressure
Slot connect by pasting reinforced hole with film, and the scraper mounting plate is close to scrape bit end equipped with connecing powder plate mounting hole.
Further, the powder plate that connects is in groove structure.
Further, the scraping blade of the scraping blade and the second scraper of first scraper is oppositely arranged, and the direction of one-way movable
On the contrary.
Further, the outlet of the waste powder hopper is equipped with third scraper.
All same principle products for not departing from the present utility model design also belong to the protection scope of the utility model.
The utility model has the following beneficial effects:
The utility model, which is used, is arranged two scrapers along photoconductor drum periphery, is connected between two scrapers by connecing powder plate, two
A scraper, photoconductor drum and connect powder plate formed a confined space, two scrapers are twice cleaned the useless powder on photoconductor drum,
The useless powder cleaned, which is fallen into, connects the progress recycling and reusing of powder plate, has saved resource and printing cost.
Two scrapers of the utility model are by the way of pasting reinforced hole, by the first fixed reinforced hole again of film, then into
The mode that row is pasted, scraping blade is not easy to fall off, does not influence print quality.
