Description
Technical field
A kind of toner cartridge for improving printing effect of the present invention, is related to laser printer technical field more particularly to a kind of improvement
The toner cartridge of printing effect.
Background technique
Laser printer is one of current most widely used computer output peripheral equipment, it using light, electricity, heat object
Reason, the principles of chemistry pass through interaction output character or image.Basic process can be divided into charging, exposure, development, transfer, fixing,
Cleaning and seven steps of electric eliminating.Firstly, photosensitive drum surface is by charging roller uniform charging；Laser scanner contains to photosensitive drums transmitting
The laser through ovennodulation of image information forms electrostatic latent image corresponding with image to be copied in photosensitive drum surface；Then, it comes from
The carbon dust of developer roll, which transfers to be adsorbed on, makes electrostatic latent image conversion can visual image on photosensitive drum surface；With photosensitive drums
Under rotation and the voltage effect applied through transfer roll to back sides such as paper, attraction is formed to the carbon dust of photosensitive drum surface, thus
The carbon powder image of imaging is transferred on paper；As under the heat effect of fixing component, carbon dust thawing is fixed on paper fibre
On；The circulation of such a imaging just completes.
After completing a basic imaging cycle, need to carry out photosensitive drums electric eliminating, present some models are to use
The mode electric eliminating of light electric eliminating makes photosensitive drums blanket exposure electric eliminating by laser irradiation, with eliminate in photosensitive drums transfer after it is residual
Remaining power grid returns to original state photosensitive drums before next duty cycle by the current potential on its surface.Current many models
For the control to cost and for the pursuit to product size is reduced, dedicated discharge system is eliminated, charging is integrated into
It in device, is charged directly in the imaging cycle of a new round, the toner cartridge of this structure prints the phenomenon that will appear ghost, i.e., previous
Wheel electrostatic latent image will affect the potential value of the electrostatic latent image of a new imaging cycle.
Summary of the invention
Insufficient for the above-mentioned prior art, the present invention provides a kind of toner cartridge for improving printing effect, and structure is simple, and can be very
The electric eliminating effect of good guarantee photosensitive drums.
To achieve the goals above, the technical scheme adopted by the invention is that: it is a kind of improve printing effect toner cartridge, include
Plastic parts, cleaning doctor, charging roller, photosensitive drums and conductive scraping blade.The plastic parts is the shell mechanism part of toner cartridge, other accessories
In installation and plastic parts；The cleaning doctor is made of metal frame and polyurethane adhesive tape, is fixedly mounted on plastic parts；It is described to fill
Electric roller is made of metal shaft and conductive cortex, is mounted on the top of cleaning doctor, parallel with cleaning doctor；The photosensitive drums with fill
Electric roller is installed in parallel on plastic parts, and photosensitive drum surface and charging roller conduction cortex are in close contact, while the glue with cleaning doctor
Cutting edge is in contact；The conduction scraping blade is the soft film of rectangle for being added to conductive material, and long side side and photosensitive drums are flat
Row is pasted and fixed on plastic parts, and one end, which is extended plastic parts and folded, is pasted onto plastic parts side, the long side other side with it is photosensitive
The tangent close contact of drum, the region that plastic parts, cleaning doctor, photosensitive drums and conductive scraping blade surround a sealing are useless for storing
Powder, when toner cartridge is installed in printer, the conductive scraping blade for exposing plastic parts side is connected to the earthing contact of machine.This structure selenium
The imaging cycle of bulging photosensitive drums is charging, exposure, development, transfer, electric eliminating and cleaning, and the carbon dust in photosensitive drums is using transfer
Afterwards, the position charge that photosensitive drums are contacted with conductive scraping blade is neutralized, and current potential is restored to 0, and new one is entered after being cleaned by cleaning doctor
The imaging of wheel, it is ensured that photosensitive drum surface current potential is 0 when charging, prevents previous round imaging cycle to the shadow of subsequent imaging effect
It rings, improves printing effect.
A kind of beneficial effect for the toner cartridge for improving printing effect of the present invention is: 1, structure is simple；2, improve printing effect.
Detailed description of the invention
Fig. 1 is a kind of accessory explosive view of toner cartridge for improving printing effect, and Fig. 2 is a kind of toner cartridge for improving printing effect
The schematic diagram of the section structure, Fig. 3 are the cleaning doctor and conductive scraping blade scheme of installation of a kind of toner cartridge for improving printing effect,
In: 1 is plastic parts, and 2 be cleaning doctor, and 3 be charging roller, and 4 be photosensitive drums, and 5 be conductive scraping blade.
Specific embodiment
The present invention is illustrated with reference to the accompanying drawing: referring to attached drawing, a kind of toner cartridge for improving printing effect of the present invention,
Include plastic parts 1, cleaning doctor 2, charging roller 3, photosensitive drums 4 and conductive scraping blade 5.The plastic parts 1 is the shell mechanism of toner cartridge
Part, other accessories installation with plastic parts 1 on；The cleaning doctor 2 is made of metal frame and polyurethane adhesive tape, is fixedly mounted on modeling
On glue part 1；The charging roller 3 is made of metal shaft and conductive cortex, is mounted on the top of cleaning doctor 2, flat with cleaning doctor 2
Row；The photosensitive drums 4 are installed in parallel on plastic parts 1 with charging roller 3, and 4 surface of photosensitive drums closely connects with the conductive cortex of charging roller 3
Touching, while being in contact with the rubber strip edges of cleaning doctor 2；It is described conduction scraping blade 5 be added to conductive material rectangle it is soft
Film, long side side is parallel with photosensitive drums 4 to be pasted and fixed on plastic parts 1, and one end, which is extended plastic parts 1 and folded, is pasted onto modeling
1 side of glue part, the long side other side and the tangent close contact of photosensitive drums 4, plastic parts 1, cleaning doctor 2, photosensitive drums 4 and conductive scraping blade
5 surround the region of a sealing for storing useless powder, and when toner cartridge is installed in printer, the conduction for exposing 1 side of plastic parts is scraped
Piece 5 is connected to the earthing contact of machine.The imaging cycle of the photosensitive drums 4 of this structure toner cartridge is to charge, expose, developing, transferring, disappearing
Electricity and cleaning, after carbon dust in photosensitive drums 4 is using transfer, the position charge that photosensitive drums 4 are contacted with conduction scraping blade 5 is neutralized,
Current potential is restored to 0, and the imaging of a new round is entered after being cleaned by cleaning doctor 2, it is ensured that 4 surface potential of photosensitive drums is 0 when charging, Du
Exhausted influence of the previous round imaging cycle to subsequent imaging effect, improves printing effect.
