Processing box

Abstract

The invention provides a processing box. The processing box comprises a rotation force transferring assembly, wherein the rotation force transferring assembly comprises a drum gear, a rotation force transferring part, a rotation force receiving head and a limitation assembly, an accommodating cavity is formed in the drum gear, an input arm is arranged on an inner wall of the accommodating cavity,the rotation force transferring part is provided with a groove part, a central shaft and a reset elastic part, an upper sliding groove and a lower sliding groove are formed in the groove part, the rotation force receiving head is matched with the upper sliding groove in a sliding way in a first direction, the central shaft is matched with the lower sliding groove in a sliding way in a second direction, the central shaft is rotatably connected with the drum gear around the axis, the central shaft can prop against the bottom of the accommodating cavity, an output arm is arranged on an outer wallof the central shaft and prop against with the input arm, the output arm is forced to deviate from the input arm by the reset elastic part, and the limitation assembly is used for limiting sliding displacement of the rotation force receiving head in a direction perpendicular to the axial direction of the drum gear and is also used for limiting the rotation force receiving head to move far away from the drum gear. The processing box can smoothly falls off and is disassembled from a main machine, and the printing performance is stable.

Description

technical field [0001] The invention relates to the technical field of printing consumables, in particular to a processing box. Background technique [0002] An electrophotographic imaging forming device such as a laser printer is a device that uses the principle of electrophotography to form an image on an image forming medium such as paper through at least the processes of charging, exposure, development, transfer, fixing, and cleaning. Consumable materials used on imaging equipment are commonly called printing consumables. Usually, the toner powder consumed by developing is generally provided by the process cartridge, and when the toner powder in the process cartridge is used up, a new process cartridge is replaced. [0003] The existing process box usually includes a powder bin, a driving part arranged on the powder bin to cooperate with the developing unit, a developing roller, a powder knife, a transmission gear, and a conductive end on the end cover of the processing...

AI Technical Summary

Problems solved by technology

[0004] In the existing process box, the rotation force transmission assembly adopts the driving connection structure of the spherical universal joint. During the transportation process, the rotation force transmission assembly is easy to detach, causing the photosensitive drum to fail to receive the transmission force, resulting in the failure of the process box. use

[0005] In addition, there is a process cartridge, the driving rod body in the rotational force transmission assembly passes through the gear positioning assembly of the positioning drive, and can slide axially reciprocatingly relative to the gear. When the process cartridge is installed and disassembled, the rotational force transmission assembly is easily connected The transmission rod of the imaging device is stuck, causing damage to the rotational force transmission assembly and the drive shaft, resulting in the process cartridge not working properly
