Embodiment 1

[0041] like Figure 3 to Figure 9 As shown, the process cartridge 10 provided by the present invention includes a waste toner bin 2 and a toner bin 1. The waste toner bin 2 includes a photosensitive drum 11. The photosensitive drum 11 is provided with a photosensitive drum driving assembly 20 that receives driving force from an imaging device. A photosensitive drum gear 12 is provided on the drum 11 . The same side of the process box 1 as the photosensitive drum drive assembly 20 is provided with a protective cover 3, the protective cover 3 is used to support and protect the gear train (not shown in the figure), the gear train includes a developing roller gear and a powder feeding roller gear, etc. .

[0042] The photosensitive drum driving assembly 20 includes a driving head arranged on the photosensitive drum gear 12 and a pushing device arranged on the protective cover.

[0043] The driving head includes a first elastic element 14 , a shaft portion 16 and a claw 15 sleeve...

Embodiment 2

[0055] The similarities between this embodiment and Embodiment 1 will not be repeated here. like Figure 13 to Figure 16 As shown, the difference between this implementation and the first embodiment is that the structure of the driving head is different.

[0056] Specifically, the drive head includes a jaw 15 and a shaft portion 16 . The number of protrusions 152 of the claw 15 is 2, and the two protrusions 152 are connected by a ring 156. The protrusions 152 extend inwardly to set a protruding wall 157, which is used to receive power from the driving head of the imaging device. The power of the transmission department.

[0057] One end of the shaft portion 16 is a first recess 161 , and the second end is a protrusion 162 . The protrusion 162 is used to cooperate with the second recess on the claw 15 to receive the driving force of the claw 15 .

[0058] The photosensitive drum gear 12 differs from the first embodiment in that the middle part of the first embodiment is dire...

Abstract

The invention relates to a photosensitive drum driving assembly and a processing box.The photosensitive drum driving assembly is detachably installed on the processing box.The processing box comprises a photosensitive drum and a protecting cover.The photosensitive drum driving assembly comprises a driving head.The photosensitive drum comprises a photosensitive drum gear.The driving head is installed on the photosensitive drum gear, and comprises a shaft part, a claw and a first elastic element.The claw is arranged on the shaft part in a sleeving mode and can stretch and contract along the shaft part.According to the photosensitive drum driving assembly and the processing box, the claw of the driving head is movable, so the problem that in the prior art, a photosensitive drum driving assembly is prone to disengagement during transportation is solved.

Description

technical field [0001] The invention relates to a photosensitive drum drive assembly and a process box, in particular to a photosensitive drum drive assembly and a process box with telescopic movement of the claws of the drive head. Background technique [0002] Generally, an image forming apparatus forms an image on a printing medium according to an input image signal. For example, printers, copiers, facsimile machines, and multifunction peripherals (MFPs) having combined functions of the above devices are included in the image forming devices. [0003] Specifically, the imaging device forms a desired image according to the following procedure. First, the surface of the photosensitive unit is charged to a predetermined potential. A laser beam is projected onto the surface of the photosensitive unit to form an electrostatic latent image. A visible image is obtained by supplying a developer to the electrostatic latent image. Next, the visible developer image developed on ...
