Abstract

The invention discloses and provides an automatic reset reset mechanism, which includes a reset gear, a spring and a stroke rod; the reset gear is provided with a pulling piece on the side facing the side cover, and the side of the shaft sleeve facing the side cover is provided with a limit position Ribs, one end of the limiting ribs protrudes from the end surface of the shaft sleeve facing the side cover, and the end of the travel rod facing the reset gear is provided with a limit notch; when assembled, the reset gear can be installed axially on the main body of the toner cartridge The drive end is provided on the gear shaft column, and can be engaged with or separated from the transmission gear, and the spring is set on the sleeve of the reset gear on the side of the drive end facing the main body of the toner cartridge, and the end surface of the sleeve on the side of the side cover It is connected with the end face of the end of the travel rod facing the reset gear, and the end of the travel rod facing the side cover runs through the stroke through hole of the side cover; when the reset gear is dislocated and separated from the transmission gear under the action of the spring, and stops rotating, the reset is automatically completed; again When installing, the reset gear is reset under the joint action of the travel lever and the limit notch.

Description

technical field [0001] The invention belongs to the technical field of printing consumables, in particular to an automatic reset mechanism and a toner box. Background technique [0002] At present, most toner cartridges on the market (such as Brother, Lenovo and other laser printing toner cartridges) have a counter reset gear. When the toner cartridge is first loaded into the printer, the gear will rotate and touch the The sensor part of the printer completes the work of counting and clearing, and then stays at a specific position (non-initial position) and does not rotate anymore. After the test is completed and the user adds powder again, the production factory must disassemble the powder box, and manually reassemble the gear to the initial position, that is, perform a reset operation, so that it can perform counting and zeroing again. Otherwise, the printer will not recognize the toner cartridge, and the toner cartridge cannot be used anymore. Generally, the user does n...
