Stirring structure for processing box and processing box thereof

Abstract

The shifting structure is applied to clutch control of a photosensitive drum and a developing roller and comprises the photosensitive drum, a drum frame, the developing roller, a developing frame and a force receiving component, and the developing frame is rotationally supported relative to the drum frame by taking a rotating axis on the developing frame as an axis; the developing frame moves between a contact position and a separation position relative to the drum frame, the developing roller is in contact with the photosensitive drum at the contact position, and the developing roller is separated from the photosensitive drum at the separation position; the force receiving component is used for receiving driving force from a driving head of the imaging equipment, the force receiving component is provided with a power receiving swing head with a backward pitching deflection receding position and a forward pitching deflection receding position, and the force receiving component is configured to move between a standby position and an operation position; when the force receiving member is at the operation position and force is applied to the power receiving swing head of the force receiving member, the developing roller can move so that the developing roller is at the separation position; the processing box is small in size, simple in structure and convenient to disassemble and assemble.

Description

【Technical field】 [0001] The invention relates to the technical field of printers, in particular to a toggle structure for a process box and the process box. 【Background technique】 [0002] A process cartridge is a consumable in an electrophotographic imaging device or a printer. It can be detachably installed in an imaging device. It usually includes a drum frame for accommodating a photosensitive drum, a developing frame for accommodating a developer, a developing roller, and a powder feeding roller. The developing frame supports A rotatable developer roller that delivers developer to the developer roller via a powder feed roller. During the working process, the process cartridge receives the driving force from the imaging device, and transmits the driving force to the photosensitive drum, developing roller and powder feeding roller through the gear set. [0003] In the prior art, as the Chinese Patent Publication No. CN102193476B discloses a process box, such as Figure ...

Problems solved by technology

However, in the existing elastic parts, in order to avoid installation of the processing box on the imaging device, the stressed part of the elastic part is designed with a depression, the overall structure is complex, the reliability is poor, and it takes up a lot of space, which makes the limited space of the processing box even more cramped and inconvenient. Processing and assembly, especially during assembly, often cause unnecessary interference, which brings a lot of inconvenience to the assembly process
