Abstract
The utility model relates to the design field of accessories of printers, specifically to a magnetic roller for a selenium drum. The magnetic roller for the selenium drum comprises a magnetic core, wherein a conducting polymer layer, a conducting surface layer and a durable absorption layer are covered outside the magnetic core in sequence. The magnetic roller for the selenium drum disclosed by the utility model solves the problems that a rubber housing is easily worn and low in absorption performance, the carbon powder cannot be absorbed uniformly, and the printed characters, images and the like are colored by powdered ink to different extents; and the magnetic roller for the selenium drum is simple in structure and principle, and can be implemented easily.
Description
Technical field
The utility model relates to printer accessory design field, specifically, relates to a kind of toner cartridge magnetic roller.
Background technology
Magnetic roller in the toner cartridge is the important accessory of laser printer, duplicating machine etc.; The main body of magnetic roller is made up of the magnetic core of the inside conductive rubber top layer outside with being enclosed within magnetic core usually; Under the action of a magnetic field of magnetic core; Carbon dust is attracted to the conductive rubber laminar surface, and after the toner cartridge energising, the carbon dust on rubber layer surface is arranged and will be transferred on the photosensitive drums.
Application number is that 201020541035.3 utility model patent just discloses a kind of toner cartridge magnetic roller, is made up of magnetic core and shell, and magnetic core is the strip structure, and rubbery outer cover wraps in the magnetic core outside, and the left end of shell has magnetic roller head, and right-hand member has magnetic roller support.
The defective that above-mentioned utility model patent exists is: the rubbery outer cover easy abrasion, and absorption property is good inadequately.Another defective is: because magnetic core directly contacts with rubbery outer cover, in use may exist between the two local conductance inhomogeneous, thereby it is inhomogeneous to make that carbon dust adsorbs, ink powders such as the literal that prints, image are painted deep mixed.
Therefore,, adapt to the needs of reality, be necessary to design a kind of novel toner cartridge magnetic roller, be intended to overcome the rubbery outer cover easy abrasion in order to overcome the deficiency of prior art, and the bad problem of absorption property.
Simultaneously, it is inhomogeneous to be intended to overcome carbon dust absorption, the painted deep mixed problems of ink powder such as the literal that prints, image.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, adapts to the needs of reality, and a kind of toner cartridge magnetic roller is provided.
In order to realize the purpose of the utility model, the technical scheme that the utility model adopts is:
A kind of toner cartridge magnetic roller comprises magnetic core, and said magnetic core outside is coated with conductive polymeric layer, conductive surface layer, wear-resisting adsorbed layer successively.
Said conductive polymer coating is identical with the resistance of conductive surface layer.
Said wear-resisting adsorbed layer is electrically-conducting paint or conduction sand.
The beneficial effect of the utility model is:
1. overcome the rubbery outer cover easy abrasion, and the bad problem of absorption property;
2. it is inhomogeneous to have solved carbon dust absorption, the painted deep mixed problems of ink powder such as the literal that prints, image; And
3. simple in structure, principle is simple, realizes easily.
Description of drawings
Fig. 1 is the sectional structure synoptic diagram of the utility model; And
Fig. 2 is the A portion partial enlarged drawing of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Embodiment: referring to Fig. 1, Fig. 2.
A kind of toner cartridge magnetic roller comprises magnetic core 1, and said magnetic core 1 outside is coated with conductive polymeric layer 2, conductive surface layer 3, wear-resisting adsorbed layer 4 successively.
The existence of conductive polymer coating 2 can be so that conductance keeps evenly, and it is inhomogeneous to have solved carbon dust absorption, the painted deep mixed problems of ink powder such as the literal that prints, image.
Said conductive polymer coating 2 is identical with the resistance of conductive surface layer 3.
Said wear-resisting adsorbed layer is 4 electrically-conducting paints or conduction sand.Wear-resisting adsorbed layer is 4 to adopt electrically-conducting paints to be coated in the outside of conductive surface layer 3, perhaps adopt conduction sand directly to spray up, and has solved effectively that conductive surface layer is 3 easy to wear, the problem of life-span end, and more helps to adsorb carbon dust.
What the embodiment of the utility model announced is preferred embodiment; But be not limited thereto, those of ordinary skill in the art is very easily according to the foregoing description; Understand the spirit of the utility model; And make different amplifications and variation, but only otherwise break away from the spirit of the utility model, all in the protection domain of the utility model.
Claims (3)
1. a toner cartridge magnetic roller comprises magnetic core, it is characterized in that: said magnetic core outside is coated with conductive polymeric layer, conductive surface layer, wear-resisting adsorbed layer successively.
2. toner cartridge magnetic roller according to claim 1 is characterized in that: said conductive polymer coating is identical with the resistance of conductive surface layer.
3. toner cartridge magnetic roller according to claim 1 is characterized in that: said wear-resisting adsorbed layer is electrically-conducting paint or conduction sand.
