Abstract
The utility model discloses a 364-type developing magnetic core for digital copiers and laser printers. A cross section of the developing magnetic core is provided with protrusions according to a revolving direction of the developing magnetic core, wherein the protrusions are identical to magnetic poles in number and protrude outwards along the center of the cross section of the developing magnetic core, so that a strip protrusion parallel to an axis of the developing magnetic core is formed in the length direction of the entire developing magnetic core, and each magnetic pole is arranged on each protrusion. By adoption of the technical scheme, interferences among all magnetic poles of an oriented magnetic field are reduced; the sizes of the magnetic poles and magnetic obliquity among the magnetic poles can be set more precisely; materials are saved, and cost is reduced; according to the usage function of each magnetic pole, the acting range of each magnetic pole can be adjusted randomly so as to improve printing quality and copying quality; and the 364-type developing magnetic core is favorable for reducing machine weight and convenient to install and use.

Shown in Figure 1 as in this Figure of description, in the prior art, the xsect of the development magnetic core 1 of digital copier and laser printer all adopts circle.
There is following shortcoming in this structure: the one, and waste material, the 2nd, the magnetic obliquity of magnetic pole is accurate inadequately, and wayward.
The utility model content
The utility model provides digital copier, laser printer 364 type development magnetic cores, its objective is economical with materials, reduces cost.
To achieve these goals, the technical scheme taked of the utility model is:
The digital copier that the utility model provided, laser printer 364 type development magnetic cores; Comprise two pairs of magnetic poles; On the xsect of described development magnetic core, by described development magnetic core gyratory directions, be provided with that quantity is identical with described number of magnetic poles, the outside convexity of cross-section center of the described development magnetic core in edge; Make whole development magnetic core form the strip projected parts that is parallel to its axis at length direction, each described magnetic pole is distributed on the described convexity.
The symmetrical center line of per two adjacent convexities forms magnetic obliquity, and wherein two magnetic obliquities are greater than 100 °, less than 120 °; Two magnetic obliquities are more than or equal to 60 °, less than 80 ° in addition.
The top of each described convexity is a circular arc, and wherein, the top arc radius of a convexity is 3mm ± 1mm, and this protruding top cambered surface width is 3.5mm ± 1mm; The arc radius on the top of other three convexities is 2mm ± 1mm, and the top cambered surface width of these three convexities is 2.5mm ± 1mm.
The circumscribed diameter of all described convexities is 17mm; The diameter of the inscribed circle of the connection, bottom of all described convexities is 12.5mm.
The utility model adopts technique scheme, and changed course magnetic core periphery is oriented to the jut orientation, reduces the interference between each magnetic pole of alignment magnetic field; Can more accurately set pole dimension and mutual magnetic obliquity, former magnetic obliquity error can be controlled in about in the of 2 ° about in the of 5 ° at present; Economical with materials reduces cost; According to each magnetic pole functions of use, can adjust the reach of each magnetic pole arbitrarily, the coupling better with other parts is provided, print and duplicate quality to improve; Alleviate machine weight, be convenient to install and use.
Description of drawings
The mark of facing down among expressed content of each width of cloth accompanying drawing of this instructions and the figure is made brief description:
Fig. 1 is the structural representation of the xsect of the described development magnetic core of this instructions background technology;
Fig. 2 is the cross-sectional structure synoptic diagram of the utility model.
Be labeled as among the figure:
1, development magnetic core, 2, magnetic pole.
Embodiment
Contrast accompanying drawing below,, the embodiment of the utility model is done further detailed explanation, inventive concept, the technical scheme of the utility model are had more complete, accurate and deep understanding to help those skilled in the art through description to embodiment.
Like the structure of the expressed the utility model of Fig. 2, for a kind of digital copier, laser printer 364 type development magnetic cores, comprise two pairs of magnetic poles 2, be respectively S1, S2, N1 and N2.
In order to solve the problem that exists at the described present known technology of this instructions background technology part and to overcome its defective, realize economical with materials, the goal of the invention that reduces cost, the technical scheme that the utility model is taked is:
As shown in Figure 2; The digital copier that the utility model provided, laser printer 364 type development magnetic cores; On the xsect of described development magnetic core 1, by described development magnetic core 1 gyratory directions, be provided with that quantity is identical with described magnetic pole 2 quantity, the outside convexity of cross-section center of the described development magnetic core 1 in edge; Make whole development magnetic core 1 form the strip projected parts that is parallel to its axis at length direction, each described magnetic pole 2 is distributed on the described convexity.
Because the cross section of development magnetic core 1 becomes quincunx (abnormity) by the above-described a plurality of convexities of having changed into of circle, under the prerequisite that guarantees same magnetic pole effect; Practiced thrift wide variety of materials; Reduce the material cost of product, simultaneously, can accurately set petal size and mutual magnetic obliquity; Reduce the interference between each magnetic pole of alignment magnetic field, improve the quality of printing and duplicating.The product weight of duplicating machine and printer is descended.
The position distribution of described convexity is:
The symmetrical center line of per two adjacent convexities forms magnetic obliquity, and wherein two magnetic obliquities are greater than 100 °, less than 120 °; Two magnetic obliquities are more than or equal to 60 °, less than 80 ° in addition.
The concrete angle of magnetic obliquity is selected according to the requirement of different product, in the hope of obtaining desirable technique effect.
