Description
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.
An existing class handle box is an integral box, the useless powder chamber that it has the carbon dust chamber that holds carbon dust and holds useless carbon dust, and the structure of such handle box is 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, carbon dust chamber framework 12 and two end caps 13,14, and wherein handle 15 is positioned on the drum frame 11.Carbon dust chamber framework 12 has a carbon dust chamber that is used to hold carbon dust, is provided with powder feeding roller 21, developer roll 25, powder delivery cutter 31 outside the carbon dust chamber.
Referring to Fig. 3, powder feeding roller 21 has a metal mandrel 22, and mandrel 22 is wrapped with elastic layer 23, is used to adsorb carbon dust.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 was installed to laser printer, conducting strip 24 contacted with the electric contact of laser printer, and laser printer provides certain voltage by electric contact to conducting strip 24.
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 service voltage from laser printer.During handle box work, the outside surface of developer roll 25 and powder delivery cutter 31 mutual extrusion make the carbon dust frictional electrification, under the effect of Electrostatic Absorption, are adsorbed on developer roll 25 outside surfaces.
The parallel axes setting of powder delivery cutter 31 and developer roll 25, it has a knife rest 32 and is installed in blade 33 on the knife rest 32, and blade 33 is used to strike off and is adsorbed on unnecessary carbon dust on developer roll 25 outside surfaces, makes the carbon dust layer thickness on developer roll 25 outside surfaces even.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 received the voltage of the supply of laser printer.
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 received the voltage of the supply of laser printer, and made the direct current that forms high pressure on the charging roller 41, 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.During laser printer work, the carbon dust that is contained in the carbon dust chamber is supplied on the developer roll 25 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, therefore powder delivery cutter 31 also needs with certain, when striking off unnecessary carbon dust, need just have the carbon dust neutralization of positive charge, make it electronegative, guarantee 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 the principle that the electric charge opposite sex is repelled each other, the carbon dust of developer roll 25 outside surfaces is repelled by unexposed area on the photosensitive drums 36.And because the voltage of exposure area is higher than the voltage of carbon dust, so the carbon dust of developer roll 25 outside surfaces delivers to the exposure 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 useless powder chamber, avoids influencing next print job cycle of photosensitive drums.
Because what laser printer loaded to the conducting strip 34 of powder delivery cutter 31 is alternating current; and carbon dust is electronegative by the friction back; therefore powder delivery cutter 31 produces absorption affinity to carbon dust when the positive half cycle of alternating current; like this; when developing; the suffered electric field force of carbon dust will weaken, and the carbon powder particle that some bulky grains or carried charge are low can not be transferred to the surface of photosensitive drums 36 effectively, have simultaneously can not be effectively in and the polarity carbon dust with positive charge.
If carbon dust electronegative deficiency or suffered electric field force deficiency, then carbon dust can't be passed to the surface of photosensitive drums 36, but falls from developer roll 25, makes the unnecessary grey point of formation on the paper, and cause the literal of printing or pattern blackness not enough, also cause the waste of carbon dust.If the polarity carbon dust of positively charged fails to eliminate or be neutralized, the positive polarity carbon dust is adsorbed on the unexposed area of photosensitive drums 36, and the zone that causes forming literal or pattern forms grey point, influences print quality.
Summary of the invention
