[0055] On the basis of the first embodiment of the process cartridge, the developing unit can also be provided with a chute on the outer wall on the same side as the driving assembly, and the chute can be extended along the installation direction or perpendicular to the installation direction. The first end of the chute is arranged at a position far away from the driving assembly, or at a position far away from any gear in the gear transmission system connected with the first gear part. And the second end of the chute is arranged at a position close to the driving assembly, or at a position close to any gear in the gear transmission system connected with the first gear part. When the processing box is in normal working condition, by setting the fixed shaft with the gear member on the first end of the chute, the touch control device will not affect the normal operation of the processing box in the normal working state of the processing box. . When the process box is pulled out...

Abstract

The invention provides a processing box. The processing box comprises a shell, a cavity for containing consumables is defined by the shell, a roller is rotationally arranged in the cavity and comprises a roller body and a driving assembly on one end of the roller body, the driving assembly comprises a gear seat and a driving force receiving part, the gear seat is provided with a containing cavity which is concave inwards axially and comprises a driven part on the inner wall of the containing cavity, the outer wall of the gear seat is provided with a first gear part, the driving force receiving part comprises a driving part in the containing cavity, a driving force receiving part outside the containing cavity and a connecting part connected with the driving part and the driving force receiving part, the driving part is connected with the driven part, the processing box is also provided with a touch control device on the shell, the touch control device is connected with the gear part and drives the first gear part to rotate, and the driven part drives the driving part to rotate. The touch control device is adjusted to solve the problem that the processing box gets stuck, and the processing box can be conveniently disassembled from a printer or installed on the printer.

Description

technical field [0001] The invention relates to the field of printing consumables, in particular to a processing box. Background technique [0002] A process cartridge is usually used in an image forming device as a toner supply source for image forming, and most existing process cartridges can be detachably installed in the image forming device for use. [0003] Usually, many rotating working rollers in the process box, such as powder feeding roller, developing roller and photosensitive drum, etc., they are commonly called rollers, and transmit power to each other through a gear system. Currently, the process cartridge has two structures. The first kind of integrated process cartridge as disclosed in U.S. patent document US5815644, the integrated process cartridge has a photosensitive drum, a developing roller, a cleaning device and a charging device, etc.; The one-piece process cartridge includes a drum cartridge and a developing cartridge. The developing cartridge is de...
