Description

A kind of coupling of main components of carbon powder box

This patent relates to a kind of HP of being applicable to Laser Jet 1010/1012/1015/1018/1020/1020plus1022/3015/3020/3030/305 2/3050/3055/M1300MFP/M1319fMFP/M1005MFP, CANONLBP-2900/3000 series printer coupling between photoconductor drum, magnetic roller, charging roller, powder delivery cutter, cleaning doctor and the ink powder in the cartridge.

At present, be applicable to photoconductor drum in the print cartridge of above-mentioned type, the magnetic roller, charging roller, the powder delivery cutter, the coupling confusion of cleaning doctor and ink powder following printing problem usually occurs at print procedure: effective usage ratio of ink powder is on the low side, the whole life-span can produce the useless powder of the not transfer printing of the surplus powder that does not use of 5～20g and 10～20g, the wasting while also to external world environment pollute; The print quality discreteness is bigger and unstable, especially in the middle and later periods in cartridge life-span, and because of each accessory depletion occurs often owing to mismate, the phenomenon of function diminuendo, the print defect showed increased can't satisfy the printing demand; The single page powder consumption is big, and print life is short partially, has only 2000 pages ± 10%, causes overall cost too high.

In order to prolong the serviceable life of cartridge, reduce and print cost, economize on resources, the present invention is by photoconductor drum, magnetic roller, charging roller, one-component negative polarity magnetic ink powder, powder delivery cutter and the cleaning doctor of apolegamy particular characteristic, make each assembly property reach optimum matching, can overcome the deficiency that present factory formula brings.

The present invention realizes by the following assembly of coupling:

1, organic light guide drum: form by aluminium base, the anti-reflection layer of conduction, charge generation layer, charge transport layer, the coating general thickness be controlled at 20 μ m～25 μ m, charge generating layer THICKNESS CONTROL in 1 μ m～2 μ m, charge transport layer THICKNESS CONTROL in 18～22 μ m, coating unevenness＜1 μ m; Coating surface resistance＞170M Ω; Charging roller to its charging after, the electric charge output layer is filled and is evenly distributed-initial potential (VO) of 650V high-pressure electrostatic lotus; Have suitable light sensitivity (E1/2), required exposure was controlled 0.1 μ J/cm when its current potential was decayed to half and is 1/2VO by initial potential (VO) ²～0.15 μ J/cm ²In the scope, make the electric charge output layer after accepting laser radiation, produce the exposure current potential (VL) of 70V～120V, formation and initial potential-450V～-the above current potential difference of 500V, and and the magnetic roller between produce rational electric field difference, the ink powder that carries on the magnetic roller can be attracted in right amount; Under no rayed and constant current potential situation, dark decay rate (DDR) is controlled at the scope of 10V～20V/S; The photoconductor drum coating is at charging roller, ink powder, medium, the long-term circulation wearing and tearing of cleaning doctor down, its rate of depreciation＜1 μ m/ photoconductor drum rotates 100,000 circles, to guarantee can not produce considerable influence to the photoelectric properties of drum.

2, magnetic roller: magnetic has good uniformity, and ink powder can evenly be adsorbed; The conductive coating roughness increases to roughness with 180 order white fused aluminas down by the air pressure with 0.14mpa and keeps Ra=1.4 μ m～1.8 μ m, the static charge of even, sufficient acquisition-650V when toner particles is rubbed between powder delivery cutter and magnetic roller.

3, charging roller: resistance value between coating and metal shaft=0.3M Ω～5M Ω, in the lucky time, make the photoconductor drum surface have density suitably, be evenly distributed-650V high-pressure electrostatic lotus; Value=HD35 ° ± 3 ° A of rubber sleeve and conductive sponge overall hardness, elasticity are good, and under the pressure of former powder box location, power spring, and the pressure control that all surface of contact produce between the photoconductor drum is in 5N～5.5N scope; The rate of depreciation that the charging roller surfaceness causes the photoconductor drum surface is rotated 100,000 circles less than 0.1 μ m/ photoconductor drum; Have certain electrical property setting range, at relative humidity RH10%～90%, the changing environment scope planted agent that temperature is 5 ℃～35 ℃ has certain stability, to eliminate, to reduce or to remedy the influence of environmental factor to photoconductor drum cloth electricity; When mains fluctuations, the accepting output characteristics and should remain unchanged substantially of charging roller; The photoelectric properties fatigue that local voltage is too high, photoconductor drum caused local damage (punctures) or acceleration photoconductor drum can not appear in charging roller and load (air-gap, optical conductor etc.) impedance phase coupling.

4, one-component negative polarity magnetic ink powder: constituent is a carbon black, magnetic oxide, resin, the ratio of lubricant and adjuvant is respectively carbon black 1%, magnetic oxide 40%, resin 55%, lubricant 3%, adjuvant 1%, make greasy property, flowing property, the colourity of ink powder reach optimum condition, the charged ability of unit volume ink powder reaches carried charge=265uc/g～290uc/g; Toner particle diameter is even, distribution range is controlled at above 1.5%, the 6.5 μ m of following 1.5%, the 8 μ m of 5 μ m～7.5 μ m more than 90%, and the carbon powder particle of participating in development and finally transfer printing is reached more than 98%; Softening point is 143 ± 1 ℃; But flowing property degree of scatter 90%～95% between the toner particle under rated condition, the nominal value limit deviation is 20%; Apparent density is 16.8g ± 1g/cm ³

5, powder delivery cutter: by stainless iron or etc. hardness rustless metal bracing frame, the PU material is magnetic roller support face and rubbing surface, require PU material corner angle, the rubbing surface flatness is good, thickness is even, hardness=HD68 ° ± 3 ° A, and elasticity is good, can be evenly when making between ink powder powder delivery cutter and magnetic roller friction, the electric charge of acquisition-650V fully, and can be uniformly by powder delivery to the gap of magnetic roller, the thickness on pressure control friction back absorption left magnetic roller surface is 0.3 ± 0.01mm, and the magnetic roller rotates 300,000 circles or places 5 years powder delivery cuttves and elastic force depletion can not occur.

6, cleaning doctor: by stainless iron or etc. hardness rustless metal bracing frame, the PU material is that magnetic roller support face and rubbing surface are formed, PU material corner angle, rubbing surface flatness are good, thickness evenly, hardness=HD73 ° ± 3 ° A and elasticity is good, and form suitable pressure between the photosensitive drums, can be good at after the photoconductor drum surface development but the carbon powder cleaning of transfer printing is unclean, photosensitive drums is rotated 100,000 circles or is placed and elastic force depletion can not occur in 5 years.

20 ℃ ± 4 ℃ of temperature, in dustless, the no static environment of relative humidity 35%～60%, the above-mentioned accessory of assembling on existing moulding, the whole print quality of cartridge is improved significantly, concrete advantage is as follows: (1) carbon dust transfer efficiency can improve 5～10 percentage points, totally be controlled at more than 95%, the useless powder of cartridge can reduce more than 80%; (2) density uniformity can improve 3～5 percentage points, can be controlled in the 1.45-1.55 interval, guarantees that print image is evenly clear; (3) the firm degree of photographic fixing can improve more than 5%; (4) conventional powder filling amount 130g ± 5g product the highest printable 3000 pages (A45% coverage rates), print life has improved 36%; (5) the whole life performance of cartridge is stable, and print quality is good, and print cost per page can be from 0.06 yuan of 0.1～0.2 yuan/Zhang Jiangzhi/open.
