Brief description of the drawings
Fig. 1 is the structural representation of experiment device of the present invention.
Label in figure：1 overhead gage, 2 charged toners, 3 copier papers, 4 insulating panels, 5 heaters, 6 panel racks, 7 connect
Ground wire, 8 lower baffle plates, 9pvc division boards, 10 plastic containers, 11 carriers, 12 ink powders.
Embodiment
The invention will be further described with reference to embodiments.
As shown in figure 1, including positive charge generator and experiment device.Positive charge generator is used to produce positive charge,
So that the negatively charged ink powder discharged on positive charge absorption experiment device, is adsorbed, so that forming corresponding root
The pattern drawn according to positive charge generator, simulate the process of printing.
Experiment device includes developer deployment device and developing apparatus, and developer deployment device includes plastic containers
11st, carrier 11 and ink powder 12, carrier 11 and ink powder 12 are inside plastic containers 11.Developing apparatus includes overhead gage 1, powered ink
Powder 2, copier paper 3, insulating panel 4, heater 5, panel rack 6, earth lead 7, lower baffle plate 8 and pvc division boards 9.Panel
Support 6 is arranged to incline structure, and insulating panel 4 is arranged on panel rack 6.Heater 5 is arranged on the back side of insulating panel 4, institute
State copier paper 3 and be arranged on the surface of insulating panel 4, the upper ends charged toner 2 of the insulating panel 4 simultaneously sets overhead gage 1
Baffle, the bottom of copier paper 3 are provided with lower baffle plate 8.Earth lead 7 is connected with copier paper 3, and the pvc division boards 9 cover
Cover on insulating panel 4.
Overhead gage 1 is made up of ambroin or plank etc., and the ink powder 2 being charged by friction uniformly is poured into overhead gage 1, is lifted
Overhead gage 1 so that ink powder 2 slowly equably flows to bottom.Paper 3 is laid in the surface of panel 4, and panel 4 is by insulating materials (modeling
Material or plank etc.) form, there is preferable hardness and flatness, with electrostatic gun electrode 13 in the surface corona of paper 3, formation
Invisible electrostatic latent image.When ink powder 2 is by paper surface 3, the charges of different polarity are attracted each other, and ink powder 2 is adsorbed in the table of paper 3
Face and form visible pattern.
In order to control the flowing velocity of ink powder 2, insulating panel 4 is formed necessarily by insulating support 6 between horizontal plane
Tilt angle theta.The design of panel tiltangleθ is acted in 40-70 scopes spent, ink powder when paper surface slides by frictional force,
Consider the coefficient of friction u of ink powder and paper, the inhibition that air drag glides for ink powder, tiltangleθ can not be too small, otherwise
Ink powder can not be slipped to bottom from paper surface.Tiltangleθ can not be too big, such as ink powder vertical drop, and movement velocity is excessive,
It is difficult to effectively be adsorbed by the charges of different polarity of paper surface and form pattern.
Toner particles very little, a diameter of 5-15 microns.Above panel 4, if semi-transparent PVC division boards 9, make panel 4
Isolate with external environment, avoid ink powder 2 from flying to be spread to surrounding space.Operator can wear mouth mask, prevent from sucking toner particles.Every
Other transparent insulating materials, such as lucite, PC plate etc. are can also be from panel 9.
The waterfall type carried out by apparatus above develops, and ink powder is insecure in the pattern that paper is formed, only by electrostatic interaction
And adsorb in paper.The heater 5 positioned at bottom plate is opened, paper surface temperature is increased to 150-200 degree, and now toner particles are melted
Change, penetrate into inside paper, form steady and audible electrostatic pattern.
The heater that the present invention designs includes following kinds of schemes, and specific heating power is needed according to panel size and paper
Open specification to determine, ensure that paper heating is rapid, panel is heated evenly.
(1) infrared lamp directly heats；
(2) electric-heating-wire-heating, it is wrapped in nickel reeling or tungsten filament in elongated quartz ampoule；
(3) xenon lamp heating is dodged, photography carries out radiant heating with stroboscopic light sources, and light application time is very short, and white paper position is not
The light sent is absorbed, black portions absorb the light of long wavelength part.
Ink powder for being lost to panel bottom, re-use, be added in powder box after being collected using lower baffle plate 8.Under
Baffle plate 8 is made using ambroin, and intensity is high, and wearability is good.
When creating significantly pattern, especially several static guns are simultaneously in paper surface output charge, such as spray positive charge
Paper is collected at, negative electrical charge existing for surrounding space can be adsorbed, causes ink powder can not be adsorbed onto paper.In paper lower position,
The chaff 7 with conducting function, such as aluminum strip and tinfoil etc. are sticked, by grounding, the unnecessary positive electricity of paper accumulation
Lotus passes through wire, is flowed into ground.
Concrete principle：
90%-97% carrier 11 and 3%-10% ink powders 12 are put into after plastic containers 11 seal and rocked up and down, is made
Ink powder 12 and the mutually friction of carrier 11 carry different electric charges.Carrier and elecrtonegativity ink powder according to a certain percentage, it is clean to pour into drying
In net sealed plastic container, rocked up and down after sealing container, make ink powder and the mutual friction of carrier phase and carry different electric charges.
Ink powder ratio in developer is controlled in 3% -10% scope, i.e. developer gross mass is 100 grams, toner mass
It is defined in the range of 3 grams -10 grams.If ink powder is excessive, carrier is surrounded by ink powder, is mainly to be rubbed between ink powder during stirring
Wipe, carrier and ink powder can not produce sufficient amount of electric charge.If ink powder is very little, paper is transferred to without enough ink powders,
Also have an impact to photocopying effect.
The shell of positive charge generator is held, electrode guard is pressed close to paper top position, mobile corona wire is duplicating
Paper writing words or depicting pattern.When creating word or image with positive charge generator, positive charge is exported by corona wire 13,
Protective cover is pressed close to paper top position, mobile corona wire writing words or depicting pattern, paper surface absorption, accumulation positive electricity
Lotus, invisible electrostatic latent image is formed, then developed with elecrtonegativity ink powder.Positive charge generator is existing electric charge
Generator, with long-living positive charge, use model EST710 positive charge generator.
Lifting overhead gage 1 makes charged toner 2 slowly equably flow to bottom.Overhead gage 1 is by structures such as ambroin or planks
Into uniformly pouring into the ink powder 2 being charged by friction in overhead gage 1, lift overhead gage 1 so that ink powder 2 slowly equably flows to bottom
Portion.Paper 3 is laid in the surface of panel 4, and panel 4 is made up of insulating materials (plastics or plank etc.), have preferable hardness with
Flatness, with electrostatic gun electrode in the surface corona of paper 3, form invisible electrostatic latent image.Ink powder 2 passes through paper
During surface 3, the charges of different polarity attract each other, and ink powder 2 adsorbs forms visible pattern on the surface of paper 3.
Opening heater 5 makes paper surface temperature be increased to 150-200 degree, and copier paper 3 forms steady and audible electrostatic pattern,
Complete experimental implementation.Ink powder is insecure in the pattern that paper is formed, and only depends on electrostatic interaction to adsorb in paper.Unlatching is located at bottom plate
Heater 5, paper surface temperature is increased to 150-200 degree, and now toner particles are melted, and are penetrated into inside paper, and it is clear to be formed
Stable electrostatic pattern.
The preferred embodiment to the invention is illustrated above, but the present invention is not limited to embodiment,
Those skilled in the art can also be made on the premise of without prejudice to the invention spirit a variety of equivalent modifications or
Replace, these equivalent modifications or replacement are all contained in scope of the present application.
