Process cartridge and regeneration method thereof

Abstract

The invention provides a process cartridge. The process cartridge comprises a developing unit and a drum unit, wherein the developing unit comprises a developing frame and a developing roller rotatably supported on the developing frame, and a developing roller gear is arranged at the axial end of the developing roller; the drum comprises a cleaning frame and a photosensitive drum rotatably supported on the cleaning frame, the cleaning frame is hinged to the developing frame through a hinged shaft, the developing unit can rotate by using the hinged shaft as a rotation center, a first driving force transmission component is arranged at the axial end of the photosensitive drum, the first driving force transmission component comprises a driving force receiving head and a driving gear, the driving gear is engaged with the developing roller gear, and the driving force receiving head is used for receiving rotation driving force; and a stressed part is arranged on the developing frame, the stressed part is positioned on the side, away from a developing chamber, of the developing frame, and the stressed part is used for receiving thrust from a printer. The invention also provides a regeneration method of the process cartridge. The process cartridge provided by the invention is simple in structure, few in components and parts, simple in production technology and easy to assemble.

Description

technical field [0001] The invention relates to the technical field of electrophotographic imaging and printing, in particular to a process box detachably installed on an electrophotographic imaging device and a regeneration method for the process box. Background technique [0002] An electrophotographic imaging device is a device that uses the principle of electrophotography to form an image on a printing medium such as paper, and includes a printer and a process cartridge detachably installed in the printer. [0003] An existing process cartridge includes a developing unit and a drum unit, the developing unit includes a developing frame and a developing roller rotatably supported on the developing frame, the axial end of the developing roller is provided with a second driving force transmission assembly, and the second driving force transmission The assembly is used to receive the rotational driving force provided by the printer to the developing roller. The developing fra...

AI Technical Summary

Problems solved by technology

When the developing roller is separated from the photosensitive drum, the developing frame rotates at a certain angle. Since the positions of the two driving shafts on the printer respectively engaged with the first driving force transmission assembly and the second driving force transmission assembly are fixed, when the developing frame rotates After a certain angle, the second driving force transmission component moves to a certain intersection position through the cross chute structure. Such a movement makes the structure of the second driving force transmission component complex, and the installation is also difficult, the process is more complicated, and the cost is relatively high. high

In addition, due to too many and small parts, it is easy to lose and confuse, which also greatly increases the complexity of the production process and the difficulty of installation
