Problems solved by technology

[0004] In the prior art, when assembling the processing box, the method of directly connecting the waste toner bin shell with the end cover is generally adopted, resulting in poor matching and positioning accuracy of the imaging device
In the prior art, there is also a method of using a complex positioning structure for positioning and then tightening, but it is often difficult to take into account the two factors of high positioning accuracy and simple assembly process, which is still a technical problem to be solved in the prior art

Embodiment 1

[0040] figure 1 It is a schematic diagram of the side sectional structure of the process box provided by Embodiment 1 of the present invention, figure 2 for figure 1 Schematic diagram of the disassembled state structure of the process box, image 3 for figure 1 Schematic diagram of the assembly state structure of the process box, Figure 4 for figure 1 Schematic diagram of the end cover structure of the middle process box, Figure 5 for figure 1 Schematic diagram of the shell structure of the waste toner bin of the middle process box. In this embodiment, a process box with a typical structure is taken as an example for illustration, as Figure 1-5 As shown, the process cartridge includes a developing chamber casing 100, an end cover 300, a waste toner chamber casing 200, and an imaging device arranged in the developing chamber 101 and the waste toner chamber 201, and the end cap 300 is vertically buckled on the developing chamber casing. The two ends of the body 100 f...

Embodiment 2

[0053] Image 6 It is a schematic diagram of the structure of the disassembled state of the process cartridge provided in Embodiment 2 of the present invention. The positioning assembly in this embodiment is a positioning convex surface 207 and a positioning concave surface 110 that abut against each other, and the direction in which the positioning convex surface 207 and the positioning concave surface 110 abut against each other as the second direction.

[0054] like Image 6 As shown, in this embodiment, what plays a role in positioning is the stepped plane that cooperates with each other. The stepped plane is preferably arranged at the end of the guiding stroke of the guide assembly. The positioned concave and convex surfaces can not only achieve abutting positioning in the second direction, but also In the axial direction of the photosensitive drum 102, the relative position between the main frame and the waste toner box housing 200 can be restricted. At this time, the ...

Embodiment 3

[0056] Figure 7 It is a schematic structural diagram of the disassembled state of the process cartridge provided by Embodiment 3 of the present invention. This embodiment provides an assembly method of the process cartridge. In this assembly method, the guide assembly is a stepped plane that cooperates with each other, and can be The guide main frame is assembled with the waste toner bin housing 200 .

[0057] The guide assembly in this embodiment is a guiding convex surface 209 and a guiding concave surface 112 that are slidably matched with each other, and the direction in which the guiding convex surface 209 and the guiding concave surface 112 slide against each other is taken as the first direction.

[0058] like Figure 7 As shown, the guiding function in this embodiment is the step-like plane that cooperates with each other. The step-like plane is preferably set at the end of the waste toner bin housing 200 and the main frame. The positioning protrusion 206 and the po...

Abstract

The invention discloses a processing box and an imaging device. The processing box comprises a main framework, a waste powder bin shell and the imaging device, wherein the imaging device is arranged in the main framework and a waste powder bin. The processing box also comprises guide assemblies and positioning assemblies, wherein the guide assemblies are respectively arranged on the main framework and the waste powder bin shell and used for guiding the assembly of the main framework and the waste powder bin shell along a first direction; and the positioning assemblies are respectively arranged on the main framework and the waste powder bin shell and used for mutually abutting and spacing on a second direction. The processing box provided by the invention has concise guiding action and accurate positioning in the assembling process, the assembling flow can be simplified, the assembling efficiency is improved, and the product cost is lowered.

Description

technical field [0001] The invention relates to a process box structure technology of an image forming device, in particular to a process box and an image forming device. Background technique [0002] A traditional electrophotographic imaging device, or image forming device, is a device that forms an image on a recording material through the principle of electrophotographic imaging. For example, electrophotographic copiers, laser printers, electrophotographic printers (such as laser printers and LED printers, etc.), fax machines and word processors, etc. An electrophotographic image forming device forms an image on a printing medium through a series of processes of charging, exposing, developing, transferring, and fixing. An electrophotographic apparatus generally includes a process cartridge detachably provided on an image forming apparatus main body. [0003] The traditional process box consists of two parts, the main frame and the waste toner box housing. During assemb...
