Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail:
Referring to shown in Figure 1, the ink powder carried charge distribution detector that the utility model embodiment provides, it comprises insulated enclosure shell 1, air exhauster 5, particle collector 6 and computing machine 8.Referring to shown in Figure 2, insulated enclosure shell 1 is cylindric, opposite polarity two charged flat boards have been arranged in parallel in the insulated enclosure shell 1: anodal flat board 4 and negative pole flat board 3, and two blocks of magnet opposite with the vertical polarity of charged flat board and that be arranged in parallel: N utmost point magnet 10 and S utmost point magnet 9, anodal flat board 4, negative pole flat board 3 link to each other with positive pole, the negative pole of power supply respectively, and the voltage between anodal flat board 4 and the negative pole flat board 3 is 3000 volts.The electromagnetic field overlay space that it is rectangle that negative pole flat board 3, anodal flat board 4, S utmost point magnet 9 and N utmost point magnet 10 surround a cross section jointly.
Referring to shown in Figure 1, the top of insulated enclosure shell 1 has the cylindrical transfer passage 2 that enters the electromagnetic field overlay space for charged toner, and this cylindrical height is 35 millimeters, and the bottom surface diameter is 2 millimeters.Spacing between two charged flat boards that are arranged in parallel is 100 millimeters, and the length of two charged flat boards is 499.5 millimeters.The bottom of insulated enclosure shell 1 is equipped with air exhauster 5.Particle collector 6 comprises induction receiving plane 7, and the induction receiving plane 7 of particle collector 6 passes insulated enclosure shell 1 bottom and enters the electromagnetic field overlay space, and particle collector 6 also links to each other with computing machine 8.
The principle of work of the utility model embodiment is elaborated as follows:
Ink powder is a kind of electrostatic material, and after friction, toner particles can be with opposed polarity and different electric weight.In the same ink powder, developer and fabricator wish the specific charge, lotus footpath of its each ink powder than identical or close, and namely the electric weight of ink powder distributes very narrow.But because in the ink powder manufacture process, filled a prescription with technique and restriction, the electric weight of its ink powder distributes always in some scopes.Because ink powder can be with upper static charge after friction, utilize the static charge radial motion that particle produces under the effect of electric field force and magnetic field force, the carried charge of testing ink powder distributes.Because varying in size of toner particles, the difference of carried charge, it is also different that ink powder is subject to the acceleration of making a concerted effort of electric field force, magnetic field force, gravity generation, so just can carry out to the charged toner particles of difference " classification " effect of making a concerted effort of an Electric and magnetic fields, make different charged toner movement of particles track generation difference, by motion is tested in the toner particles particle diameter test of a certain track and the quantity of particle, namely can make charge-distribution curve and the lotus footpath scatter chart of an ink powder.
The below describes with the data instance among the utility model embodiment.
Distance is D=0.1 rice between two flat fields, and institute's making alive is 3000 volts, electric field E=60000 volt/rice.Magnetic field intensity is 0.5 spy between two magnets.The length L capable of regulating of cylindrical shape insulated enclosure shell, length L is 0.5 meter, the mobile conveyance conduit of charged toner stretches in the test cylindrical shell as far as possible, design length is 35 millimeters, ink powder is left be in behind the conveyance conduit relatively uniformly in the uniform electric field and magnetic field a plurality of circular natural air inlet mouths of test cylindrical shell top design, diameter is 1cm, be beneficial to an interior Air Flow, the particle collector lower end is designed with filter paper, is beneficial to adsorb toner particles and air is flowed out.The testing tool bottom is designed with air exhauster, is beneficial to the outflow of air, makes the Air Flow of measuring in the cylindrical shell form advection as far as possible, can adjust inner core length according to the height of carried charge in the time of during survey and adapt to the ink powder of testing.
Test process is because ink powder is charged after rubbing with carrier, carry by a bolter with air-flow, ink powder is separated with carrier, carrier is tackled by screen cloth, charged ink powder then can owing to the drive that is subjected to air-flow continues to move, enter in the Electric and magnetic fields with certain speed by being gathered in a small aperture.Under the interaction of this Electric and magnetic fields, the direction that charged toner particles then can occur under electric field and the magnetic fields power moves, as long as make Electric and magnetic fields act on the power of charged toner and the perpendicular direction of its initial velocity in the design process, and can allow charged toner direction of motion be offset.By testing the size of its offset distance, can calculate the size of carried charge.Pass through again particle collector and grain graininess deflection angle measuring and calculation, can make the carried charge scatter chart of ink powder, referring to shown in Figure 3.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.The content that is not described in detail in this instructions belongs to the known prior art of this area professional and technical personnel.
