Embodiment 1

[0042] like Figure 1 to Figure 12 As shown, the process box 10 provided in this embodiment includes a toner bin 1 and a waste toner bin 2 , and also includes a protective cover 3 . The protective cover 3 is arranged on one side of the toner bin 1 and the waste toner bin 2 . The powder bin 1 contains carbon powder, a developing roller, a powder feeding roller and a scraper. A photosensitive drum is arranged in the waste toner bin 2, and a photosensitive drum gear and a driving head are arranged at one end of the photosensitive drum.

[0043] The process cartridge 10 provided in this embodiment further includes a photosensitive drum driving assembly 20, and the photosensitive drum driving assembly 20 includes a forcing device and a photosensitive drum driving head arranged on the end cover. The driving head includes claws, and the pushing device can make the claws move telescopically along the driving head.

[0044] The process cartridge 10 provided in this embodiment include...

Embodiment 2

[0062] Such as Figure 13 to Figure 16 Shown is the photosensitive drum drive head assembly and the process cartridge provided in the second embodiment, which is different from the first embodiment in that the pushing device further includes a push block 27 . The push block 27 is further provided with a fourth elastic element 28 , the push block 27 is disposed in the recess of the protective cover 3 , and the fourth elastic element 28 connects the push block 27 and the protective cover 3 respectively. In addition, optionally, the protective cover 3 further includes a baffle 6 , and the support holes 23 may be provided on the baffle 6 . The baffle 6 is used to cover the recess of the protective cover 3 .

[0063] The push block 27 includes a first end for contacting with the imaging device cover and a second end opposite to the first end, an opening 270 is arranged on the top near the first end, a support column 271 is positioned in the opening, and the push block 27 is basic...

Embodiment 3

[0069] Such as Figure 17 to Figure 20 Shown is the photosensitive drum driving assembly and the process cartridge provided by the third embodiment, and its similarities with the second embodiment will not be repeated, the difference is that the structure of the push block 27 is different, specifically, the push block 27 includes a first The opening 270 and the second opening 274, the push block 27 includes a first end and a second end, the first end is used to receive the forcing force of the imaging device, such as the cover of the imaging device. The second end is in contact with the supporting part 150 of the claw 15, and an arc-shaped guiding surface is provided thereon. The fourth elastic element 28 is disposed between the first openings 270 and is respectively connected to the pushing block 27 and the protective cover 3 . Under normal conditions, under the action of the fourth elastic element 28, the pushing block 27 moves toward the first end, and after the first end ...

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 pushing device and a driving head. The driving head comprises a clamping claw and a shaft part. The photosensitive drum comprises a photosensitive drum gear, the driving head is installed on the photosensitive drum gear, and the pushing device comprises a sliding block and a lever. The sliding block and the lever are installed on the protecting cover, and the pushing device makes the clamping claw perform telescopic motion in the direction parallel to the axial direction of the photosensitive drum. According to the photosensitive drum driving assembly and the processing box, the problem that in the prior art, photosensitive drum driving assemblies drop easily in 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) that have combined functions of the above devices are all 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 the photo...
