Process cartridge as well as installation method and removal method thereof

Abstract

The invention provides a process cartridge as well as an installation method and a removal method thereof. The process cartridge comprises a cartridge body, a roller and a driving force transmission component, wherein the roller is rotatably supported on the first end wall and the second end wall of the cartridge body; the driving force transmission component is positioned at the side of the firstend wall of the cartridge body and is connected with the roller in a driving way; the driving force transmission component is used for receiving a driving force; the process cartridge also comprisesa driving mechanism; the driving mechanism is arranged on the second end wall of the cartridge body; the driving mechanism drives the cartridge body to move along the length direction of the cartridgebody; the driving mechanism comprises an elastic part and an elasticity release component; the elasticity release component is installed on the elastic part and compresses the elastic part; the direction of an elastic restoring force of the elastic part is parallel to the length direction of the cartridge body. By means of the cooperation of the elastic part and the elasticity release component,the translation of the process cartridge in an imaging apparatus is realized, so that the connection and separation of the driving force transmission component on the process cartridge and a drive shaft in a printer are further realized.

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 imaging device and a method for installing and taking out the process box. Background technique [0002] An imaging device is a device that uses the principle of electrophotography to form images on printing media such as paper, including copiers, printers, fax machines, all-in-one machines, etc., and usually includes a host and a process box detachably installed in the host. Wherein, the processing box is provided with a rotating element and a rotating force transmission assembly that receives the rotating driving force provided by the main machine such as a printer. The rotating element includes at least one of a developing element, a photosensitive drum, and a charging element. After the processing box is installed on the main machine, it rotates The force transmission component cooperates with the drivi...

Problems solved by technology

This kind of ball-type universal joint is easy to come out of the gear, or deviate from the direction, especially in the process of transportation, this phenomenon is more likely to occur. Cause the loss of the transmission function of the ball universal joint or the work is unstable

In order to make the ball universal joint cooperate with the driving mechanism of the main machine, it is usually necessary to set up torsion springs and stoppers to position it, which increases the number of parts and complicates the structure of the processing box

[0004] In addition, the Chinese patent literature with the publication number CN103376696A discloses a process cartridge whose rotational force transmission assembly has a telescopic function, including a drive rod and a gear assembly, and the drive rod moves back and forth relative to the axial direction of the gear assembly. When the process box is installed and removed, the components are easily stuck with the drive rod in the printer, resulting in damage to the drive rod of the process box and the drive rod of the printer, making the process box unable to work normally
