Description

A kind of Delevoping cartridge

Technical field

This utility model relates to a kind of Delevoping cartridge being detachably mounted on photosensitive drums box.

Background technology

Electrophotographic imaging forming apparatus is, by electrophotographic image forming principle, visual image is formed on the recording medium Plant imaging device, including electrophotographic copier, electrophotographic printer and LED printer etc..In electrophotographic imaging forming apparatus Generally all including being detachably mounted to handle box therein, handle box it is frequently necessary to change as easy consumption product.

Generally including two kinds in existing handle box, a kind of is integral type, and another kind is split type.Split type place Reason box is generally made up of Delevoping cartridge and photosensitive drums box two parts, and both are combined by specific connected mode.Delevoping cartridge one As by housing, gear train, developer roll, the component composition such as powder outlet cutter, thus provide developing agent to photosensitive drums box.Photosensitive drums box is general By waste developer reservoir, cleaning doctor, charging member, photosensitive drums etc. form, and wherein photosensitive drums receives the aobvious of developer roll offer Shadow agent and form electrostatic latent image.Operation principle in above-mentioned electrophotographic imaging forming apparatus is: charging member rushes to photosensitive drum surface The uniform electric charge of last layer, the light scanning unit in electronic imaging apparatus sends the photosensitive drum surface after light is irradiated to charging, shape Becoming electrostatic latent image, developing agent is delivered to the electrostatic latent image district of photosensitive drum surface thus is formed visually at photosensitive drum surface by developer roll Developer image, the transfer printing unit in electronic imaging apparatus by described visual developer image to record medium in, Finally by heating and fixation unit by fixing for visual developer image in the recording medium, finally defeated from electronic imaging apparatus Go out.

In split type handle box, the developer roll in Delevoping cartridge and the photosensitive drums in photosensitive drums box must keep close Coordinate, imaging process to keep constant gap, developer roll and photosensitive drums will not be affected because of the vibration in print procedure Cooperation.One would generally be increased in photosensitive drums box to compel to push away assembly, arrange in Delevoping cartridge one with compel to push away what assembly coordinated Power acceptance division, when Delevoping cartridge loads to photosensitive drums box, compels to push away assembly and compels thrust acceptance division so that Delevoping cartridge is close to photosensitive drums Box.

A kind of handle box disclosed in prior art, the urgent assembly that pushes away in photosensitive drums box includes compeling pushing block and flexible member, aobvious The first power acceptance division and the second power acceptance division it is respectively arranged with, when Delevoping cartridge is installed to photosensitive drums on the two side of the housing of shadow box Time on box, the described urgent pushing block compeling to push away in assembly pushes away the first power acceptance division and the reception of the second power in the effect tenesmus of flexible member Portion, makes the developer roll in Delevoping cartridge keep coordinating closely with the photosensitive drums in photosensitive drums box, thus ensures the steady of imaging device Fixed work.But in above-mentioned Delevoping cartridge, power receives parts and is all disposed within housing so that the die sinking difficulty of housing increases, when When technique or other errors cause production waste product occur, owing to the reason of power acceptance division causes whole housing to be scrapped, submit an expense account cost Height, is unfavorable for the energy-conserving and environment-protective of enterprise, adds entreprise cost and burden simultaneously.

Utility model content

Big in order to solve prior art middle shell die sinking difficulty, when technique or other errors cause production waste product occur, Reimbursement cost is high, is unfavorable for the energy-conserving and environment-protective of enterprise, the problem simultaneously adding entreprise cost and burden, and this utility model uses Techniques below scheme:

A kind of Delevoping cartridge being detachably mounted to be provided with on the photosensitive drums box compeling to push away assembly, including:

Housing, its internal reservoir has developing agent, including the first side wall and the second sidewall；

Developer roll, including development roll shaft, on the development rotatable the first side wall being supported in housing of roll shaft and the second sidewall；

Protecting cover, is installed on the first side wall of housing；

Conducting bracket, is installed on the second sidewall of housing；

Puddle support, including stirring framing shaft, on the rotatable the first side wall being supported in housing of stirring framing shaft and the second sidewall；

Power acceptance division, including the first power acceptance division and the second power acceptance division；

First power acceptance division is arranged on protecting cover.

First power acceptance division and the second power acceptance division are at least partially disposed between developer roll and stirring framing shaft.

First power acceptance division and the second power acceptance division and the contact position compeling to push away assembly be positioned at developer roll and stirring framing shaft it Between.

First power acceptance division extends in a first direction near the side of housing from protecting cover, and first direction is roughly parallel to development Roller axial direction.

Second power acceptance division extends from conducting bracket in a second direction, and second direction is generally perpendicular to the first direction.

First power reception portion is arranged on protecting cover by technique scheme, solves prior art middle shell die sinking difficult Degree is big, when technique or other errors cause production waste product occur, owing to the reason of power acceptance division causes whole housing to be scrapped, and report Pin cost is high, is unfavorable for the energy-conserving and environment-protective of enterprise, the problem simultaneously adding entreprise cost and burden.
