But, because there is error in the assembling of each toner cartridge, and the power acted in transmission process on photosensitive drums and developer roll is also fluctuation, and the number of powder also can have an impact to the size of acting force, thus, photosensitive drums and developer roll is made to remain the state fully contacted, the elastic force of spring 4A wants interference, although ensure that photosensitive drums remains with developer roll so fully to contact, but pressure when photosensitive drums and developer roll contact is sometimes very large, photosensitive drums can be caused like this to wear and tear large, and can cause carbon dust also pressurized stick to photosensitive drum surface, cleaning doctor all cannot be removed.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of printer toner cartridge developer roll buffer structure.
The utility model solves the technical scheme that its technical matters adopts:
A kind of printer toner cartridge developer roll buffer structure, the developer roll comprising limit lid, photosensitive drums and contact with photosensitive drums, developer roll is provided with powder storehouse, photosensitive drums is provided with waste powder hopper, pinned connection is passed through between waste powder hopper and powder storehouse, and be provided with spring between waste powder hopper and powder storehouse, it is characterized in that: described limit covers and is provided with holding tank, being provided with in this holding tank can the back-up block of movement in this holding tank, described back-up block is provided with axis hole, the spindle nose of described developer roll is positioned at this pilot hole, is provided with the flexible member that can push up only back-up block in described holding tank.
Described flexible member is Compress Spring, and one end of this Compress Spring and one end of back-up block are pushed up and pressed, and the inwall top of the other end and holding tank is pressed.
Described holding tank is rectangle, and described back-up block is square, and is positioned at holding tank top, and described Compress Spring is positioned at bottom holding tank.
The two rectangular grooves that described holding tank comprises T-slot and is communicated with T-slot, described back-up block is T-type structure and is positioned at T-slot, and described flexible member is positioned at rectangular groove.
The beneficial effects of the utility model are: the utility model is by with front, the pilot hole covered for assembling developer roll spindle nose makes holding tank into, slidably back-up block is set in holding tank, pilot hole is arranged in back-up block, and back-up block is fixed in holding tank by the top pressure of flexible member.Pass through said structure, when in transmission process, when the elastic force of the spring when between waste powder hopper and powder storehouse makes the contact between photosensitive drums and developer roll excessive, by compression elastic element, developer roll is moved down, reduce waste powder hopper and and powder storehouse between the elastic force of spring, thus the contact also reduced between photosensitive drums and developer roll, avoid photosensitive drums wearing and tearing large, and cause carbon dust also pressurized stick to photosensitive drum surface, the shortcoming that cleaning doctor all cannot be removed, and better assembling, production efficiency are high.
