Toner cartridge counting gear resetting assembly and toner cartridge

Abstract

The invention discloses and provides a toner cartridge counting gear resetting assembly and a toner cartridge. The toner cartridge counting gear resetting assembly comprises a counting gear (1), a driving gear (2), an end cover (3) and a toner stirring rod (4) connected with the driving gear (2); the driving gear (2) is connected with the toner stirring rod (4) by a pawl structure; the driving gear (2) can unidirectionally and independently rotate on the toner stirring rod (4); a tension spring (5) is arranged on the end cover (3); by the tension spring (5), the driving gear (2) is in close contact with the toner stirring rod (4); and the counting gear (1) is arranged on a positioning pillar (6) inside the end cover (3) and is in contact with a resilience device (7) inside the end cover (3). The toner cartridge counting gear resetting assembly and the toner cartridge are applicable to the field of the toner cartridge.

Description

technical field [0001] The invention relates to a carbon powder box counting tooth reset assembly and the carbon powder box. Background technique [0002] At present, major toner cartridge manufacturers will conduct a full print test on the toner cartridge to ensure the quality of each toner cartridge. After the toner cartridge is loaded into the printer during the print test, the printer drives the gear set to rotate to drive The counting gear rotates, and the counting tooth rotates to the counting switch of the printer, and the counting switch of the printer is pushed up by the limit pin on the top to confirm the machine is complete. After the printing test is completed, the counting gear in the toner cartridge and the direction of the transmission gear will change. If there is a change, it is not in the initial assembly position, and the counting gear needs to be readjusted to return to the initial position before the toner cartridge can be used normally. At present, majo...

Problems solved by technology

[0003] Solution 1: Disassemble all the side covers at both ends of the powder box, and reassemble all the gears so that the counting gear and the transmission gear are in the specified position. This solution can correctly ensure that the counting gear and the transmission gear are in the specified position, but the process is quite cumbersome and After disassembly and assembly, it is difficult to ensure the printing quality of the toner cartridge, causing unnecessary printing defects;

[0004] Solution 2: Rotate the entire transmission mechanism by rotating the external drive head, so that the counting gear and the transmission gear are at the specified position. Because the drive head is not at the same end as the counting gear and the transmission gear, it is difficult to observe whether the specified position is reached during rotation, and the drive The transmission ratio between the head and the counting gear and the transmission gear is relatively large. After the drive head rotates for many times, the position of the counting gear and the transmission gear changes very little, the operation is complicated, and it is difficult to ensure that the counting gear and the transmission gear are in the specified position during production, causing the printer to fail to recognize Toner cartridge
