A kind of existing handle box includes developing cell and drum unit, and developing cell includes developing frame and is pivotably supported
Developer roll on developing frame, the axial end of developer roll are provided with the second driving force transfer unit, the second driving force transmission group
Part is used to receive the rotary driving force that printer is supplied to developer roll, and developing frame has developing room and toner accommodating chamber, shows
Studio is located at the top of toner accommodating chamber, and developer roll is located in developing room.Drum unit includes cleaning frame member and rotatable twelve Earthly Branches
The photosensitive drums in cleaning frame member are supportted, cleaning frame member is hinged with developing frame by hinge, and developing cell can be using hinge as rotation
Turning center to be rotated, photosensitive drums be arranged in parallel with developer roll, and the axial end of photosensitive drums is provided with First Driving Force transmitting assembly,
First Driving Force transmitting assembly includes driving force and receives head and drive gear, and First Driving Force receives head and carried for receiving printer
Supply the rotary driving force of photosensitive drums.
, it is necessary to clear up the useless powder in photosensitive drums and the transfer belt of printer in time in print procedure, printing is prevented
Unfavorable condition.When push rod above printer is applied to the forced position on developing frame, make the developer roll on developing frame
Separated with the photosensitive drums in cleaning frame member, at this moment First Driving Force transmitting assembly turns after receiving the driving force effect that printer provides
Dynamic, in charging roller charge and discharge process, the useless powder taken of quoting of printer is transferred in photosensitive drums, and then cleaned scraper is made
With making the useless powder in photosensitive drums be transferred in the waste powder hopper of cleaning frame member, realize the automated cleaning of photosensitive drums and printer.Development
When roller separates with photosensitive drums, developing frame turns an angle, due on printer respectively with First Driving Force transmitting assembly and
The position of two drive shafts of the second driving force transfer unit engagement is changeless, when developing frame turns an angle
Afterwards, the second driving force transfer unit is moved to by cross chute structure at certain crossover location, such movement, makes second
The complicated of force transfer unit is driven, installation is also more difficult, and technique is more complicated, and cost is higher.Further, since parts
It is too many and small, it is easily lost and obscures, is also added significantly to the complexity of production technology and the difficulty of installation.
Utility model content
Main purpose of the present utility model is to provide that a kind of simple in construction, simple for assembly process to be easy to implement photosensitive drums clear
It is clean, while ensure the handle box of print quality.
From such scheme, the utility model, which provides a kind of handle box, includes developing cell and drum unit, developing cell
Including developing frame and the developer roll being pivotally supported on developing frame, the axial end of developer roll is provided with development roller tooth
Wheel, developing frame have developing room and toner accommodating chamber, and developing room is located at the top of toner accommodating chamber, and developer roll is positioned at aobvious
In studio.Drum unit includes cleaning frame member and the photosensitive drums being pivotally supported in cleaning frame member, cleaning frame member and developing frame
Frame is hinged by hinge, and developing cell can be rotated by pivot of hinge, and photosensitive drums be arranged in parallel with developer roll, sense
The axial end of light drum is provided with First Driving Force transmitting assembly, and First Driving Force transmitting assembly includes driving force and receives head and driving
Gear, drive gear engage with developing roller gear, and driving force receives head and is used to receive rotary driving force；It is provided with developing frame

Drive shaft drives photosensitive drums to continue to rotate, and realizes the cleaning of photosensitive drums.Due to cleaning photosensitive drums when the second drive shaft not with processing
Box contacts, and when forced section receives the thrust from printer, developer roll can with drive gear with photosensitive drums and developing roller gear
More swimmingly to separate, the structure of the rotation driving force transfer mechanism of handle box of the present utility model is simple, and parts are few, production
Technique is simple and assembling is easy.
One preferable scheme is that elastic component is provided between developing frame and cleaning frame member, and elastic component is located under hinge
Side, the both ends of elastic component are connected on developing frame and cleaning frame member respectively.
As can be seen here, elastomeric element plays a part of support when developer roll contacts with photosensitive drums, while in elastomeric element
In the presence of power, the side that cleaning frame member is laterally away under developing frame is pushed, because elastic component is located at the lower section of hinge,
Thus the developer roll on the upside of developing frame is pushed to photosensitive drums side, makes developer roll and photosensitive drums steady with certain pressure
Surely contact, to ensure print quality.Other elastomeric element carries after developer roll separates with photosensitive drums for the reset of developing frame
It is made for exerting oneself.
Further scheme is that mounting post is provided with developing frame, and the appearance of mounting post autography framework is towards cleaning
Framework side extends, and elastic component is set in mounting post.
As can be seen here, the setting of mounting post prevents elastomeric element from being come off from handle box.
One preferable scheme is that the quantity of elastic component is two, and two elastic components are located at the length of developing frame respectively
Close to the opening position at developing frame both ends on direction.
As can be seen here, two elastic components support developing frame and cleaning frame member from the both ends of developing frame, so that development
Contact between roller and photosensitive drums is uniform.
One preferable scheme is that the quantity of elastic component is one, and an elastic component is located on developing frame close to stress
The opening position of portion one end, is provided with support member in cleaning frame member, and support member be arranged in parallel with elastic component and is connected to developing frame
On, support member is located at the opening position away from forced section one end in cleaning frame member.
As can be seen here, during developer roll and photosensitive drums are contacting and separating, support member abuts with developing frame all the time, with
Just ensure stably to contact between developer roll and photosensitive drums, meanwhile, when the setting of elastic component ensures to clean photosensitive drums, show
Shadow roller is tilted and separated relative to photosensitive drums, so as to realize the cleaning to photosensitive drums.
One preferable scheme is that forced section is the projection that autography framework extends downwardly, and force part is in developing frame
One end of upper close developing roller gear.
As can be seen here, according to lever principle, developing roller gear is made to be realized in the presence of less power and drive gear
Separation, so as to realize the separation of developer roll and photosensitive drums.
One preferable scheme is that powder feeding roller is additionally provided with developing room, and powder feeding roller be arranged in parallel with developer roll, powder feeding roller
Axial end be provided with the powder feeding roller gear engaged with developing roller gear.
As can be seen here, developing roller gear provides rotary driving force to powder feeding roller gear, and it is swimmingly developer roll to make powder feeding roller
For powder, so as to ensure print quality.
