Abstract
A kind of toner cartridge of corona wire charging, it is related to a kind of laser printer technical field, include glue part shell, corona wire, cleaning doctor, electric eliminating hairbrush and photosensitive drums, carbon dust after imaging is after photosensitive drums are transferred on printing paper, in the case where photosensitive drums persistently rotate, the adhesive tape of cleaning doctor scrapes the residual carbon dust in photosensitive drums, and collects into waste powder hopper, electric eliminating hairbrush removes charge remaining in photosensitive drums, and photosensitive drums enter the work period of next charging development.Due to the effect of cleaning doctor, when electric eliminating hairbrush carries out electric eliminating to photosensitive drums, the carbon dust of noresidue, is not in the situation that carbon dust is accumulated on electric eliminating hairbrush, influences the effect of electric eliminating hairbrush, so as to extend the service life of toner cartridge in photosensitive drums.
Description
Technical field
A kind of toner cartridge of corona wire charging of the utility model, is related to laser printer technical field more particularly to a kind of electricity
The toner cartridge of dizzy silk charging.
Background technology
In existing toner cartridge product, two kinds can be divided by charging modes classification, one kind is to photosensitive with charging rubber roller
Drum charges, and one kind is to be charged using corona wire discharge mode to photosensitive drums.Photosensitive drum surface obtains it through overcharge
Certain potentials are obtained, are loaded with the exposure of the laser beam of picture-text image information later, just form electrostatic latent image in photosensitive drum surface, are passed through
Magnetic roller or developer roll development, sub-image are transformed into visible carbon dust picture, when by transfer area, are transferred on printing paper, pass through
Carbon dust is fixed on paper by heating fixing.Before the printing picture and text information cycle of a new round, the selenium for the rubber roller charging structure that charges
Drum has that cleaning doctor is clean by the useless powder of photosensitive drum surface, the toner cartridge of corona wire charging structure, most of to use electric eliminating hair
Brush carries out photosensitive drum surface electric eliminating and cleaning or unclean is directly entered next printing interval.
Using the toner cartridge of corona wire structure, occur the situation of useless powder heap product after much time using, on electric eliminating hairbrush,
Photosensitive drum surface is caused to give up, and powder is excessive, and the defects of bottom ash or nigrescence occurs in printing, can not be continuing with, so as to influence toner cartridge
Service life causes the printing cost of the wasting of resources and user to increase.
Invention content
In view of the shortcomings of the prior art, the utility model provides a kind of toner cartridge of corona wire charging.
To achieve these goals, technical solution is used by the utility model.
A kind of toner cartridge of corona wire charging, includes glue part shell, corona wire, cleaning doctor, electric eliminating hairbrush and photosensitive drums；Institute
It states glue part shell and includes waste powder hopper, waste powder hopper is used for collecting the useless powder of storage；The corona wire, cleaning doctor, electric eliminating hairbrush and sense
Light drum is mounted on glue part shell；The corona wire is parallel installation with photosensitive drums, is maintained a certain distance, by corona wire
The auxiliary voltage between photosensitive drums will be close to the air ionization of corona wire and make its electric discharge, so as to photosensitive drum charging；It is described clear
The installation parallel with photosensitive drums of clean scraper, the adhesive tape on cleaning doctor are acted in photosensitive drums；The electric eliminating hairbrush is put down with photosensitive drums
Row is installed and is contacted with each other.
Carbon dust after imaging is after photosensitive drums are transferred on printing paper, and in the case where photosensitive drums persistently rotate, cleaning is scraped
The adhesive tape of knife scrapes the residual carbon dust in photosensitive drums, and collects in waste powder hopper, and electric eliminating hairbrush is by electricity remaining in photosensitive drums
Lotus is removed, and photosensitive drums enter the work period of next charging development.Due to the effect of cleaning doctor, electric eliminating hairbrush is to photosensitive drums
When carrying out electric eliminating, the carbon dust of noresidue, is not in the situation that carbon dust is accumulated on electric eliminating hairbrush, influences electric eliminating hair in photosensitive drums
The effect of brush, so as to extend the service life of toner cartridge.
Description of the drawings
Fig. 1 is a kind of overall structure diagram of the toner cartridge of corona wire charging of the utility model：1 is glue part shell, and 2 be sense
Light rouses, and 3 be cleaning doctor, and 4 be electric eliminating hairbrush, and 5 be corona wire, and 11 be waste powder hopper.
Specific embodiment
The utility model is illustrated below in conjunction with the accompanying drawings：With reference to attached drawing 1, a kind of corona wire charging of the utility model
Toner cartridge include glue part shell 1, corona wire 5, cleaning doctor 3, electric eliminating hairbrush 4 and photosensitive drums 2；The glue part shell 1 includes useless
Powder cabin 11, waste powder hopper 11 are used for collecting the useless powder of storage；The corona wire 5, cleaning doctor 3, electric eliminating hairbrush 4 and photosensitive drums 2 are installed
On glue part shell 1；The corona wire 5 is parallel installation with photosensitive drums 2, is maintained a certain distance, by corona wire 5 and sense
Auxiliary voltage between light drum 2 will be close to the air ionization of corona wire 5 and make its electric discharge, so as to charge to photosensitive drums 2；It is described clear
Clean scraper 3 and 2 parallel installation of photosensitive drums, the adhesive tape on cleaning doctor 3 are acted in photosensitive drums 2；Photosensitive drums 2,3 and of cleaning doctor
Glue part shell 1 forms the waste powder hopper 11 of a closed area；The electric eliminating hairbrush 4 is parallel with photosensitive drums 2 to be installed and contacts with each other.
Carbon dust after imaging is after photosensitive drums 2 are transferred on printing paper, in the case of photosensitive drums 2 persistently rotation, cleaning
The adhesive tape of scraper 3 scrapes the residual carbon dust in photosensitive drums 2, and collects into waste powder hopper 11, and electric eliminating hairbrush 4 will be in photosensitive drums 2
Remaining charge is removed, and photosensitive drums 2 enter the work period of next charging development.Due to the effect of cleaning doctor 3, electric eliminating hair
When 4 pairs of photosensitive drums 2 of brush carry out electric eliminating, the carbon dust of noresidue, is not in that carbon dust is accumulated on electric eliminating hairbrush 4 in photosensitive drums 2
Situation influences the effect of electric eliminating hairbrush 4, so as to extend the service life of toner cartridge.
