Processing box and counting mechanism

Abstract

The invention relates to a processing box and a counting mechanism, the processing box comprises a shell and an end cover, and the counting mechanism is assembled on the end cover; the counting mechanism comprises a gear piece and a detection piece; the gear piece comprises a limiting part and a guiding part; the first end and the second end of the guide part and the limiting part are arranged inthe circumferential direction of the addendum circle of an outer gear at intervals. The extending height of the first part of the guide part from the inner bottom wall of the gear piece is gradually increased, the extending height of the second part of the guide part from the inner bottom wall of the gear piece is unchanged, the detection piece comprises a positioning part located on the inner side wall, the positioning part protrudes towards the axis of the outer gear relative to the outer side wall of the limiting part and the guide part, and the positioning part and the limiting part at least partially coincide. The first part and the second part directly push the detection piece to move, gears are meshed to indirectly push the detection piece, the prior art that the detection piece isdirectly pushed through gear meshing is omitted, the assembly precision requirement between the stirring frame and the counting mechanism is lowered, the assembly is convenient, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of imaging equipment, and in particular relates to a processing box and a counting mechanism. Background technique [0002] In commercially available imaging equipment (printers, copiers and facsimile machines, etc.), a process box with a band counting mechanism that is detachably installed on the image forming device is widely used, and the information detection mechanism on the image forming device and the process box are used. The counting mechanism realizes the detection of whether the process cartridge mounted thereon is a new process cartridge. However, most of the existing counting mechanisms are initially toggled by meshing with the gear of the stirring rack. The detection part and the gear part of the counting mechanism are integrally formed in the counting mechanism, so as to ensure reliable contact between the detection rod and the information detection mechanism. As a result, the assembly precis...

However, most of the existing counting mechanisms are initially toggled by meshing with the gear of the stirring rack. The detection part and the gear part of the counting mechanism are integrally formed in the counting mechanism, so as to ensure reliable contact between the detection rod and the information detection mechanism. As a result, the assembly accuracy between the stirring frame and the counting mechanism is high, which in turn causes assembly inconvenience and reduces production efficiency
