Description

Handle box
Technical field
The present invention relates to a kind of printing consumables, especially a kind of handle box that is used for laser printer.
Background technology
Laser printer is common printing device, for modern office provides great convenience.Existing laser printer uses the handle box that is releasably attached in the laser printer to provide mostly and prints the carbon dust that uses, and in print procedure, the carbon dust transfer printing that handle box loads forms required pattern and literal on the paper as print media.
The waste powder hopper that an existing class handle box has the toner of holding carbon dust and holds useless carbon dust, the structure of such handle box as shown in Figure 1.
Referring to Fig. 1, handle box has a housing 1, and housing 1 is provided with a handle 15, is convenient to the user and holds.
Referring to Fig. 2, the housing 1 of handle box is made up of drum frame 11, toner framework 12 and two end caps 13,14, and wherein handle 15 is positioned on the drum frame 11.Toner framework 12 has a toner that is used to hold carbon dust, is provided with powder feeding roller 21, developer roll 25, powder delivery cutter 31 outside toner.
Drum frame 11 has a waste powder hopper, is used to hold waste and old carbon dust, and the waste powder hopper peripheral hardware has photosensitive drums 36, charging roller 41 and cleaning doctor 48.During the handle box assembling, drum frame 11 is connected and fixed by end covers at two sides 13,14 with toner framework 12, and drum frame 11, toner framework 12 and end cap 13,14 surround a cavity, and parts such as powder feeding roller 21, developer roll 25, powder delivery cutter 31, photosensitive drums 36, charging roller 41 and cleaning doctor 48 are positioned at this cavity.
Referring to Fig. 3, powder feeding roller 21 has a metal mandrel 22, mandrel 22 is wrapped with elastic layer 23, and the two ends of mandrel 22 extend to outside the elastic layer 23, and powder feeding roller 21 is used for cleaning to developer roll 25 supply carbon dusts and to the residual carbon dust in developer roll 25 development rear surfaces.End at mandrel 22 is connected with a conducting strip 24, and conducting strip 24 extends to outside the end cap 14.After handle box is installed to laser printer, conducting strip 24 contacts with the electric contact of laser printer, laser printer provides the voltage of a definite value by electric contact to conducting strip 24, is used for eliminating carbon dust segment polarity electric charge and the electric field force of enough development bias voltage is provided.
Similarly, developer roll 25 also has a metal mandrel 26, and mandrel 26 is wrapped with elastic layer 27, and as sponge, rubber etc., an end of mandrel 26 also is connected with conducting strip 28, and conducting strip 28 outer ends extend to outside the end cap 14.Conducting strip 28 is connected with another electric contact of laser printer, receives the voltage from the supply of laser printer.During handle box work, developer roll 25 outside surfaces and carbon dust are adsorbed on carbon dust on developer roll 25 outside surfaces by electrostatic interaction.
Powder delivery cutter 31 be arranged in parallel with developer roll 25, it has a knife rest 32 and is installed in blade 33 on the knife rest 32, blade 33 flexibly is pressed on the outside surface of developer roll 25 vertically, being used to control the carbon dust layer thickness evenly distributes on the developer roll surface, also provide certain extruding force, make it charged with the friction carbon dust to developer roll 25.One end of knife rest 32 is connected with conducting strip 34, and an end of conducting strip 34 extends to outside the end cap 14.After handle box was installed to laser printer, conducting strip 34 was used to receive the laser printer power supply.
The parallel axes setting of photosensitive drums 36 and developer roll 25, the outside surface of photosensitive drums 36 is a photographic layer, the carbon dust of developer roll 25 outside surfaces can be transferred to the outside surface of photosensitive drums 36.
Turn to by the work of photosensitive drums 36 and to see that its upstream is provided with charging roller 41, charging roller 41 has metal mandrel 42, the mandrel 42 outer conductive layers 43 that are provided with, and conductive layer 43 contacts with the outside surface of photosensitive drums 36 and powers to photosensitive drums 36.One end of mandrel 42 is set with a support 44, and spring 45 is installed on the support 44, and spring 45 is connected with conducting strip 46.After handle box was installed to laser printer, conducting strip 46 was used to receive laser printer power supply, and made on the charging roller 41 and form high voltage direct current, thereby to photosensitive drums 36 chargings, made photosensitive drums 36 outer surface belt negative electricity.
The downstream of photosensitive drums 36 is provided with cleaning doctor 48, is used to strike off the carbon dust that remains in photosensitive drums 36 outside surfaces after transfer printing finishes.
Referring to Fig. 4, the carbon dust of developer roll 25 outside surfaces is transferred to the outside surface of photosensitive drums 36 by electric field force.During laser printer work, the carbon dust that is contained in the toner supplies to developer roll 25 outside surfaces by powder feeding roller 21, constantly rotates during powder feeding roller 21 work, and its sense of rotation is shown in arrow A among Fig. 41.
The abut outer surfaces of powder feeding roller 21 and developer roll 25, the carbon dust that therefore will be adsorbed on outside surface in powder feeding roller 21 rotary courses is transferred to the outside surface of developer roll 25, also constantly rotation during developer roll 25 work, its sense of rotation is shown in arrow A among Fig. 42.In developer roll 25 rotary courses, the unnecessary carbon dust of its outside surface will striking off through powder delivery cutter 31, blade 33 strikes off and is adsorbed on the blocked up carbon dust of developer roll 25 outside surfaces, thereby guarantees the thickness of developer roll 25 outside surface carbon dust layers, makes developer roll 25 outside surface carbon dust layer thicknesses even.
The lotus because the part carbon dust can become positively charged inadequately, the perhaps electronegative deficiency of part carbon dust, so powder delivery cutter 31 also needs electronegative, when striking off unnecessary carbon dust, negative charge on the blade need be transferred on the carbon dust, be guaranteed that developer roll 25 outside surface carbon dusts have uniform negative charge.
On the other hand, charging roller 41 makes photosensitive drums 36 outside surfaces electronegative equably to photosensitive drums 36 chargings.In laser printer when work,, laser instrument has the laser of image information to photosensitive drums 36 surface irradiations, and this process is an exposure process, forms latent images in irradiated zone, photosensitive drums 36 surfaces, and promptly the exposure area electric charge disappears, and is electric neutrality.
Because unexposed area is electronegative on the photosensitive drums 36, and the exposure area is an electric neutrality, and the carbon dust of developer roll 25 outside surfaces is also electronegative, according to electric charge in electric field principle, the carbon dust of developer roll 25 outside surfaces, to under the effect of electric field force, move to exposure area on the photosensitive drums 36 by developer roll 25 outside surfaces.And because the development bias voltage that the electric field force in territory, non-exposed area is higher than, so the carbon dust of developer roll 25 outside surfaces can not move to the territory, non-exposed area of photosensitive drums 36 outside surfaces, and this process is a developing process.
At last, from photosensitive drums 36 below processes, carbon dust will be transferred on the paper as the paper of print media, and on paper, finish by print job through heating back photographic fixing for carbon dust.
After photosensitive drums 36 is finished transfer process, cleaning doctor 48 will strike off the carbon dust that remains in photosensitive drums 36 outside surfaces, and useless pruinescence is collected and entered waste powder hopper, avoids influencing next print job cycle of photosensitive drums.
Because different carbon dusts obtain the ability of electric charge and are not quite similar, and the powder feeding roller of unlike material is to the adsorptive power and the transfer charge ability difference of different carbon dusts, and the voltage that this requirement is carried on the powder feeding roller need be adjusted according to the characteristic of different carbon dusts and powder feeding roller material.
But laser printer is fixed to the magnitude of voltage that powder feeding roller loads, often cause being carried in the brownout on the powder feeding roller and cause the deficiency of carbon dust electric field force in electric field, or polarity carbon dust that can't neutral zone positive electricity.If the electric field force deficiency of carbon dust place electric field, then carbon dust can't be passed to the surface of photosensitive drums 36, causes the literal of printing or pattern blackness not enough.If the polarity carbon dust of positively charged fails to eliminate or be neutralized, then the carbon dust of positive polarity will be adsorbed on the unexposed area of photosensitive drums 36, and the zone that causes forming literal or pattern forms grey point, influences print quality.
