Embodiments of the present disclosure may be performed independently of each other or may be performed together in an interdependent relationship.

Referring to fig. 1 and 2, the utility model discloses a powder box counting reset gear, which comprises a gear main body 1, wherein the gear main body 1 is in a flat circular table shape, a tooth-free surface 2 and a gear surface 3 meshed with a transmission gear 4 are arranged on the annular side surface of the gear main body 1, an arc section 5, a first stirring column 6 and a second stirring column 7 for stirring a sensor stirring sheet of a printer are arranged on the upper end surface of the gear main body 1, and the arc section 5, the first stirring column 6 and the second stirring column 7 are all positioned on the annular edge of the upper end surface of the gear main body 1, and because the arc section 5, the first stirring column 6 and the second stirring column 7 are required to stir sensor components in a printer shell, namely counting induction sheets, the positions of the counting induction sheets are required to be arranged on the annular edge of the upper end surface of the gear main body 1 and are sequentially arranged, so that the sensor components can be stirred sequentially.

Because the arc section 5, the first stirring column 6 and the second stirring column 7 are required to stir the sensor component for a certain time, the first stirring column 6 and the second stirring column 7 cannot be too thick, so that the contact time with the sensor component is too long and inaccurate, the first stirring column 6 and the second stirring column 7 are designed to be thinner, and in order to increase the strength of the sensor component, the connecting plate 8 is designed to connect the first stirring column 6 and the second stirring column 7.

As shown in the figure, a limit part 9 is arranged on the upper end surface of the gear main body 1; the lower end face of the gear main body 1 is provided with a retaining part 10, and the limiting part 9 and the retaining part 10 are square blocks and are connected with a shaft barrel 11, so that the strength of the gear main body is improved. The gear body 1 is provided with a shaft 11, and the shaft 11 is provided with a shaft hole 12 penetrating the shaft 11 and the gear body 1.

The counting self-resetting gear can be matched with an automatic resetting mechanism for use when in use, for example, the counting self-resetting gear is used with the following patent numbers: 202221730179, the specific structure of the automatic reset mechanism is not described in detail.

The working principle of the self-resetting gear is briefly described: this count is from reset gear through shaft hole 12 and automatic reset mechanism's pivot cooperation thereby rotatory, when this count is from reset gear cooperation reset mechanism installs in the printer printing, depression bar subassembly touches the inner wall of printer and pushes down, and count is from reset gear and printer's drive gear through drive gear 4 is connected thereby rotatory, arc section 5 and sensor part contact and stir the sensor part always this moment, then first stir post 6 with the second stir post 7 stir the sensor part in succession, then continue to rotate, works as spacing portion 9 rotates to depression bar subassembly department, spacing portion 9 is blocked by the depression bar subassembly, count gear stops rotating and accomplish the process of counting zero clearing and confirm the machine, and no tooth face 2 just is towards drive gear 4 this moment, drive gear 4 idly, count is from reset gear can not rotate this moment, in order to prevent count from reset gear reverse rotation, of course prevent through setting up torsional spring 13 and pushing down the holder 10.

When the toner cartridge is pulled out of the printer, the compression bar assembly is sprung upwards, so that the counting self-resetting gear cannot be blocked from rotating, the torsion spring 13 extrudes the holding part 10 to enable the counting gear to continue rotating to an initial position to finish resetting, and the next process of finishing counting zero clearing is waited to be continuously finished in the printer.

The above description of the embodiment of the utility model provides a powder box counting reset gear, and specific examples are applied to the description of the principle and the implementation mode of the utility model, and the description of the above embodiments is only used for helping to understand the method and the core idea of the utility model; meanwhile, as those skilled in the art will have variations in the specific embodiments and application scope in accordance with the ideas of the present utility model, the present description should not be construed as limiting the present utility model in view of the above.
