For solving the problems of the technologies described above, the technical problems to be solved in the utility model is to provide that a kind of cost is low, energy-conserving and environment-protective, the printer of lightweight and the novel developer roll of copier toner.
The technical solution adopted in the utility model is: a kind of novel developer roll for printer and copier toner, comprise a conduction rotating shaft, described conduction rotating shaft is provided with a nonmetal conductive foaming layer outward, and described nonmetal conductive foaming layer is provided with the conduction gum cover that a smooth outer surface is wear-resisting outward.
Described nonmetal conductive foaming layer is hollow cylinder body structure, and described hollow cylinder is set in conduction rotating shaft, and described conduction gum cover is set on hollow cylinder.
Described nonmetal conductive foaming layer is porose foaming layer or atresia foaming layer.
Described nonmetal conductive foaming layer is doped with the foamed plastic of conductive materials or bipeltate or foamed rubber-plastic mixture.
Described bipeltate is a kind of and multiple combination in polyurathamc rubber, foaming ECO rubber, foaming EPDM rubber and foaming NBR rubber.
Described conduction gum cover is doped with the plastics gum cover of conductive materials or rubber gum cover or rubber and plastic mixture gum cover.
Described hollow cylinder both ends of the surface are respectively provided with an annular hard gasket, the external diameter of described annular hard gasket is less than or equal to the external diameter of hollow cylinder and is greater than the external diameter of conduction rotating shaft, the longitudinal length of described conduction gum cover is greater than hollow cylinder body length, covers the conduction gum cover two end portions towards conduction rotating shaft and hot melt bending on described annular hard gasket.
The beneficial effects of the utility model:
The utility model developer roll adopts expanded material to replace traditional closely knit rubber layer, and expanded material outside the conduction gum cover of sheathed smooth abrasion-proof, expanded material and the cost of gum cover of conducting electricity are low, technique is simple, energy-conserving and environment-protective are lightweight, are easy to carry;
Nonmetal conductive foaming layer is hollow cylinder, and this hollow cylinder is set in conduction rotating shaft, and conduction gum cover is set on hollow cylinder, so developer roll assembly process is simple, has improved production efficiency;
Conduction gum cover two ends are respectively arranged with an annular hard gasket, make the utility model developer roll possess the rigidity of traditional closely knit rubber developer roll, are difficult for shake or skew occur when toner cartridge is worked, and have guaranteed development quality.
