Abstract
The utility model relates to a developer box, which comprises a casing and a developer roller, and the developer roller can be supported on both length end sides of the casing in a rotating way; a developer roller end seal is arranged between the end of the developer roller and the wall of the casing; a developer scraper blade is arranged on the developer roller, and has that a first length edge with the both ends lapped with the developer roller end seal, a second length edge arranged the side being closed to the developer roller with the length being shorter than the first length edge and the both ends being not lapped with the developer roller end seal, a breadth edge intersected with the first length edge and lapped with the developer roller end seal, wherein the second length edge is connected with the breadth edge through a sloping portion with a notch. The utility model has the advantage that the utility model can prevent the developer from accumulating at the end of the developer roller.
Description
Technical field
The utility model relates to a kind of developer box.
Background technology
The developer box of imaging device generally includes a housing, and enclosure interior is provided with developer-accommodating chamber, developer roll, the powder feeding roller of receiving photographic developer.Wherein, developer roll and powder feeding roller rotatably are supported on the distolateral wall of two length of housing.For preventing that developer from revealing between the sidewall of the end of developer roll and housing, between the end of developer roll and housing, be provided with end seal.For adjusting the developer layer thickness on developer roll surface, on the housing wall on developer roll top, developer blade is installed, this developer blade and developer roll outer circumference surface Elastic Contact are charged with the thickness of developer layer on the even maintenance developer roll and to developer.Generally, the outer circumference surface Elastic Contact with developer blade and developer roll is called the adjusting part with the zone of regulating developer layer thickness.If the adjusting of developer blade part is isometric with developer blade, its end overlaps in the end seal of developer roll, flexing can take place in the elasticity extruding that is subjected to developer roll, cause developer blade inhomogeneous to the contact pressure of developer roll in the longitudinal direction, make developer roll surface development agent layer thickness inhomogeneous, influence the development quality.
No. 20060216072 U.S.'s publications of US disclose a kind of developer blade, wherein the two ends of developer blade are cut jagged respectively, the adjusting part that makes developer blade does not overlap each other with the end seal of developer roll, thereby has avoided developer blade inhomogeneous to the contact pressure of developer roll in the longitudinal direction.But in indentation, there, developer blade is piled up so developer easily because of viscous effect is bonded in herein, forms because of can't accept the extruding of developer roll.The developer that is deposited in indentation, there can not in time be got back in the developer-accommodating chamber, can be tired because of being recharged for a long time, and lead electrical property and descend, influence the development quality.
The utility model content
The technical problems to be solved in the utility model provides a kind of improved developer box, developer can not produced in the indentation, there of developer blade pile up.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: developer box comprises: housing; Developer roll rotatably is supported on the distolateral wall of two length of housing; The developer roll end seal is between the end and housing wall portion of developer roll; Developer blade is installed in the top of developer roll, and it has: first length sides, two ends and developer roll end seal overlap joint; Second length sides is positioned near the developer roll side, and its length is shorter than first length sides, and two ends do not overlap with the developer roll end seal; Width edge intersects with first length sides, and with developer roll end seal crossover; Wherein, second length sides is connected by a sloping portion that has breach with width edge.
Scheme is the inboard to housing one side that described barbed portion is positioned at the developer roll end seal preferably.
Another better scheme is the inboard to housing one side that described breach all is positioned at the developer roll end seal.
Better scheme is that described breach is being circular arc with described sloping portion intersection.
Developer box with said structure, what connect second length sides of developer blade and width edge is notched sloping portion.This sloping portion can produce expulsive force to developer in the course of the work, and the developer at the second length sides two ends end to developer roll is promoted.When developer was pushed into indentation, there, developer can be got back to the developer-accommodating chamber from indentation, there because of the expulsive force effect of sloping portion, promptly can not be deposited in indentation, there, also can not leak from the two ends of developer roll.

Fig. 2 is the partial structurtes synoptic diagram of the utility model developer box;
Fig. 3 is the developer blade structural representation of the utility model developer box;
Fig. 4 is the assembling synoptic diagram of developer blade, developer roll, developer roll end seal and the developer box housing of the utility model developer box;
Fig. 5 A-Fig. 5 F is the developer blade partial structurtes synoptic diagram of the utility model developer box.
Below in conjunction with accompanying drawing embodiment of the present utility model is introduced in detail.
Embodiment
Referring to Fig. 1, Fig. 2, the developer box 100 that is used for image processing system is made up of housing 1 and the cap 2 that covers this housing 1 upper opening.Be provided with developer-accommodating chamber 11 and development chamber 12 in the housing 1, be communicated with by powder supply port 13 between the two.Developer-accommodating chamber 11 is used to store developer, and its inside is equipped with and is used to stir and the stirring apparatus 3 of supplying developing agent.In development chamber 12, contiguous powder supply port 13 places are provided with donor rollers 4, are provided with developer roll 5 with donor rollers 4 parallel contacting.Developer roll 5, donor rollers 4 all rotatably are supported on the distolateral wall 15 of two length of housing 1 along the length direction of developer box 100.Above developer roll 5, be provided with the developer blade 6 that can be used as the developer charging unit, it is fixed on the developer blade supporting walls 16 of housing 1 by developer blade frame 7.Developer blade 6 can contact with the surface elasticity of developer roll 5, regulates the developer layer thickness on developer roll 5 surfaces.
For preventing that developer from revealing between the end wall 15 of the end of developer roll 5 and housing 1, between the end wall 15 of the end of developer roll 5 and housing 1, also be provided with developer roll end seal 8.
Referring to Fig. 3, Fig. 4, developer blade 6 is plates, has first length sides 61, second length sides 62, width edge 63 and is connected the sloping portion 64 of second length sides 62 and width edge 63.
For the intersection that prevents breach 64 and sloping portion 64 forms the sharp-pointed angle of cut, thereby scratch the circumferential surface of developer roll 5, breach 641 is slick and sly arc with the intersection 642 of sloping portion 64.
The breach 641 of sloping portion 64 can have the polygon gabarit of rule, also can have irregular curve gabarit, and Fig. 5 A to Fig. 5 F shows several frequently seen breach 641 shapes, but the shape of breach 641 is not limited to the shown shape of Fig. 5 A to Fig. 5 F.
Variation based on the utility model design is not limited in the foregoing description, also multiple variation can be arranged, and these simple structural changes still belong to the protection domain of the utility model requirement.
