Description

A kind of clutch buffer and its handle box

【Technical field】

The utility model is related to drive technologies in imaging device more particularly to a kind of slow for the clutch in imaging device Flushing device and its handle box.

【Background technology】

In general, in known process cartridge system, electrophotographic photosensitive member in imaging device and it is applied to it Processing unit is integrated into box, which can be removably installed in image forming apparatus body；Such as laser printer duplicates In the electrophotographic image formings such as machine, facsimile machine, it is typically provided with a handle box, which can be from electrophotographic image forming In take apart, in order to which user can safeguard the device in process cartridge system, help to improve operability.

Existing handle box has following a few classes：One kind is photosensitive drums and developing apparatus, charging unit and cleaning device composition Integral box；Another kind of seperated box or photosensitive drums and the developing apparatus assembly for being photosensitive drums and charging unit is assembled together Seperated box together；Wherein, developing apparatus includes main body, transmission side, conductive side and memory unit package, moreover, Delevoping cartridge Photosensitive drums on be both provided with receive rotary driving force and drive photosensitive drums mechanism.

No matter which kind of integration mode, the processing component that rotates is needed in imaging process as long as having in box, be required for from Electrophotographic image forming receives driving force, with driving processing component rotation.

Existing HP/CANON producers are designed using universal joint drive power receiving member and actuator for universal joint, one end Be arranged in a cylindrical element of handle box end, the other end is prominent to outside Delevoping cartridge, for in electrophotographic image forming Drive shaft engages, and universal joint can directly drive photosensitive drums or developing cell to rotate after receiving driving force.But this universal joint drive Part easily falls off out of cylindrical element, to can not steadily transmit driving force, and the driving force receiving part of this class formation at This price is higher with respect to the producer of compatible driving mode.

And the producer of existing compatible driving mode, such as hundred million platinum, martial prowess, Sai Na, compatible producer mostly use greatly mechanical-assisted pendulum Arm come make driving head assembly with taking-up process realize axial stretching either using strength be packed into or removal method so that driving Power component engages with machine driving force component and is detached from effect, and pushes swing rod that driving force is connect using machine switch door closure By component axes stretch mode, there are risks of instability for structure.

For the driving head using telescoping mechanism, when being packed into or taking out by force, equipment is being packed into developing cell After handle box, after shutting door closure, driving head starts to rotate, and at this moment, there are two shapes in a device for the handle box with developing cell State, i.e. working condition and off working state, working condition are the pulling force effect of the operating lever accepting device on handle box, and control is high The driving head of speed rotation is engaged with the rotary power receiving part of developing cell on handle box；Off working state is on handle box Operating lever accepting device thrust, the rotary power for controlling high-speed rotating driving head and developing cell on handle box connects Receive component quick separating；Therefore, the handle box with developing cell is in handoff procedure in off working state and working condition, by Motionless rotary power receiving part is detached or is engaged under high speed impact with the driving head of high-speed rotation, causes driving head and rotation There are the Contact -impacts of hard collision for rotatory force receiving part；Further cause to fall machine that there are driven when certain angles are transferred to Component does not engage with machine driving head and leads to problems such as to skid, and driving head is engaged with machine driving part when taking-up It blocks or the problems such as bounce impact force is big.
