Description

Power receiving member and powder cartridge

[ technical field ] A method for producing a semiconductor device

The utility model relates to a print technical field, especially relate to a powder section of thick bamboo.

[ background of the invention ]

The powder cylinder is a replaceable consumable material for an application and laser electronic imaging device and is used for providing developer for the electronic imaging device. The powder cartridge includes a cartridge body for storing the developer, a discharge port for discharging the developer, and a power receiving end for receiving power from the electrophotographic apparatus. The power receiving end enables the developer to be more smoothly discharged to the electronic imaging device through the forms of driving the stirring frame or driving the cylinder body to rotate and the like.

In the prior art, there are schemes that use an air pump type structure to help the developer to be conveyed to the discharge port through air flow, and there are also schemes that use a gear to drive a fan to convey the developer to the discharge port through air flow. These solutions rely on air flow to entrain the developer and therefore have transport problems when the developer is poorly defined. Meanwhile, due to the fact that the scheme uses air flow, the precision requirement is high, and the production cost is high.

[ detailed description ] embodiments

Example one

Fig. 1 is a perspective view of a powder cartridge. As shown in fig. 1, the powder cartridge includes a cylindrical body a10 and a fixed mounting portion a 20. When the powder cartridge is mounted on the electronic image forming apparatus, the fixed mounting portion a20 is fixed to the electronic image forming apparatus by one or more of a rail, a projection, a hook, and the like provided on the surface thereof. When the powder cartridge is operated in the electrophotographic apparatus, the fixed mounting portion a20 and the electrophotographic apparatus remain relatively stationary. A receiving gear a11 is also provided on the cylinder a10 for engaging with and receiving a rotational driving force from the electronic image forming apparatus. Preferably, the receiving gear a11 is disposed on the outer surface of the barrel a10, and the receiving gear a11 lies on a plane perpendicular to the barrel a 10. Further preferably, the receiving gear a11 encircles the barrel for one revolution.

FIG. 2 is a cross-sectional view of the powder container taken along a plane passing through the rotational axis of the container body. As shown in fig. 2, a drive gear a14 is also provided at the free end opening a13 of the cylinder a10 near the fixed mounting portion a 20. Preferably, the drive gear a14 is a bevel gear and the drive gear a14 is disposed in one revolution around the free end opening a 13. When the receiving gear a11 receives a driving force from the electronic image forming apparatus, the entire cylinder a10, including the driving gear a14, rotates about the rotation axis of the powder cartridge cylinder. On the side of the fixed attachment portion a20, a driven gear a22 is provided. Preferably, the driven gear a22 is a bevel gear that meshes with the drive gear a 14. By these two bevel gear structures, the direction of the gear rotation axis is changed by 90 degrees, and the power rotating around the cylinder a10 is converted into power directed to the rotation axis. Of course, other mechanical structures for changing the direction of the rotation axis of the gear in the prior art can be used instead.

The fixed mount a20 is fixed to the electronic image forming apparatus, and the driven gear a22 located inside the fixed mount is rotatably fixed to the fixed mount a 20. A powder outlet a21 is provided at a position below the fixed mounting portion a20 for discharging the developer from the powder outlet a21 out of the powder cartridge to flow into the electrophotographic apparatus. The fixed mounting part a20 is further provided with a powder suction pipe a24 extending into the cylinder a10, and a rotatable spiral stirring frame a25 is provided inside the powder suction pipe a 24. Preferably, the powder suction tube a24 is provided in a hose structure or a structure that fits the inner wall of the barrel a10, thereby ensuring that the powder suction tube a24 is always located at a position below the inside of the barrel a10 regardless of whether the barrel a10 is rotated. The driven gear A22 directly or indirectly drives the helical agitator A25. Preferably, an idler gear a23 is provided for connecting the driven gear a22 and the driving helical agitator frame a 25. The idler gear a23 is connected to the driven gear a22 on one side and to the helical agitator frame a25 on the other side. Preferably, the idler gear a23 and the driven gear a22 may be coaxially arranged, and the connection between the idler gear a23 and the helical agitator frame a25 may be arranged by a universal joint or a bevel gear (not shown in the drawings), so as to accomplish 90-degree conversion of the direction of the rotation axis.

When the cylinder a10 rotates, the cylinder a10 indirectly drives the helical agitator a25 to rotate through the aforementioned transmission process, thereby smoothly sucking the developer from the powder cartridge cylinder into the stationary mounting portion a20 and then discharging the developer from the powder outlet a21 to supply the electrophotographic apparatus.

Preferably, the helical agitator frame a25 is configured in a curved configuration as shown in fig. 2, and may be configured in multiple stages, i.e., the configuration shown in fig. 2 is configured as a three-stage helical agitator frame connection configuration, so as to avoid interference during rotation.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
