Description

Selenium drum

Technical Field

The utility model relates to a laser imaging prints technical field, especially laser imaging prints the technical field of required consumptive material.

Background

The laser printing device can realize the printing function only by consuming a developer such as carbon powder. During printing, toner needs to be transported from the toner storage container to the core of the cartridge. Toner cartridges are typically provided with an integral powder bin for storing the toner required by the cartridge. However, the storage capacity of the powder bin is limited, and the service life of the core component of the cartridge is long, so that the core component of the cartridge still has use value after the carbon powder in the powder bin is used up.

In order to avoid wasting the use value of the core component of the toner cartridge, a toner replenishing container for replenishing toner to the toner cartridge is designed. Namely, after the carbon powder in the powder bin carried by the toner cartridge is consumed, the carbon powder can be supplemented into the powder bin by using the carbon powder supplementing container, so that the toner cartridge can continuously exert the use value.

The conventional method for replenishing the toner hopper of the toner cartridge with toner is to fill the toner in the toner replenishing container into the toner hopper through a toner replenishing port on the toner hopper of the toner cartridge during the period of the toner cartridge being out of service. In addition, there is a way to replenish the toner: the carbon powder replenishing container is connected with the toner cartridge and communicated with a carbon powder replenishing port on the toner bin, so that carbon powder is replenished to the toner bin of the toner cartridge at any time when the toner cartridge works. The latter carbon powder replenishing container has the advantages of simple operation and less environmental pollution.

The carbon powder replenishing container can replenish carbon powder to the powder bin of the toner cartridge at any time when the toner cartridge works, and the carbon powder can be conveyed to the powder bin of the toner cartridge through gravity. However, since the space for accommodating the carbon powder in the carbon powder replenishing container is narrow, the efficiency of conveying the carbon powder by gravity is low, and even a large amount of carbon powder cannot enter the powder bin due to local aggregation and blockage of the carbon powder formed in the carbon powder replenishing container, which causes waste.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem that the carbon powder in the carbon powder replenishing container is easy to generate the waste, the utility model provides a toner cartridge.

Detailed Description

The technical solution of the present invention will be described in detail below with reference to the embodiments shown in the drawings.

Fig. 1 shows the assembly position relationship and concrete structure of the toner cartridge 2 and the toner replenishing container 1 matched with the toner cartridge of the present invention. The toner cartridge 2 is provided with a toner hopper 205. The powder bin 205 is integrated on the cartridge to form an integrated cartridge. The powder hopper 205 is provided with a toner replenishment port 206 at an upper position as viewed in fig. 1. A carbon powder stirring shaft (not shown in the figure due to shielding of the housing of the powder bin 205) is arranged in the powder bin 205. The carbon powder stirring shaft is also provided with a flaky stirring blade. One end of the carbon powder stirring shaft extending out of the powder bin 205 is provided with a powder bin gear 202. The rotation axis of the powder bin gear 202 is coincident with the rotation axis of the carbon powder stirring shaft. The powder bin gear 202 is engaged with a driving gear for driving the photosensitive drum of the toner cartridge to rotate, so that the driving gear can also drive the powder bin gear 202 to rotate, further drive the carbon powder stirring shaft to rotate in the powder bin 205 and stir the carbon powder therein, so as to convey the carbon powder and avoid the carbon powder from gathering and blocking, thereby creating conditions for the smooth entering of the supplemented carbon powder.

The following gears are provided outside the cartridge 2 in sequential engagement: transmission gear 203, gear 204, gear 201. The transmission gear 203, the gear 204 and the gear 201 form a transmission gear group. Wherein the transmission gear 203 is meshed with the powder bin gear 202. Therefore, the rotational force of the powder hopper gear 202 can be transmitted by the transmission gear group.

The toner replenishing container 1 has a toner container for accommodating toner, and a toner stirring shaft is provided in the toner container, and a gear 101 is provided at an end of the toner stirring shaft extending out of the toner container. A toner replenishment passage 103 is provided in communication with the toner container. The toner replenishment path 102 is sized to fit the toner replenishment port 206 so that the two are in close communication. The toner replenishing container 1 is also provided with a retainer 102. The fixing member 102 is matched with a corresponding fixing member (not shown) on the toner cartridge 2, and the fixing member and the toner cartridge 2 can form a fixing relationship after being connected, so that the toner replenishing container 1 can be fixed on the toner cartridge 2 when the toner replenishing channel 102 and the toner replenishing port 206 are tightly communicated. When the toner replenishment container 1 is fixed to the cartridge 2, the

gears

101 and 201 are engaged. As can be seen from the foregoing, the transmission gear set including the gear 201 can transmit the rotating force of the powder bin gear 202 to the gear 101, so as to drive the carbon powder stirring shaft in the carbon powder container, thereby preventing the carbon powder in the carbon powder replenishing container from being accumulated or blocked, and enabling the carbon powder to be more efficiently conveyed to the powder bin of the toner cartridge. The powder bin gear 202 and the matched transmission gear set shown in fig. 1 are arranged at the right end of the toner cartridge, and in other embodiments, the powder bin gear and the matched transmission gear set can also be arranged at the left end, and of course, the corresponding toner replenishing container can also be arranged at the left end.

Fig. 2 shows the assembled state of the toner replenishing container 1 and the toner cartridge 2, and the meshing relationship between the gear 101 and the transmission gear set, which is meshed with the toner hopper gear 202.

In other embodiments, the other end of the toner cartridge may also be provided with a powder bin gear and a transmission gear as shown in fig. 1, that is, both ends of the carbon powder stirring shaft disposed in the powder bin of the toner cartridge are provided with powder bin gears, and certainly, the powder bin gears are also respectively provided with a transmission gear set. When the carbon powder replenishing container and the powder bin are equal in length, the driving force for driving the carbon powder stirring shaft can be given from the two ends of the carbon powder replenishing container, so that the carbon powder stirring shaft is balanced in stress and runs more stably.
