the powder feeding roller is partially accommodated in the sealing door, can rotate relative to the sealing door and comprises two shaft ends and a roller positioned between the two shaft ends;
wherein,
and a plurality of powder feeding grooves which are arranged along the axial direction are uniformly distributed on the periphery of the surface of the roller.
The utility model discloses a toner cartridge compares with prior art, and the powder feeding structure of powder feeding roller is sent powder or sponge by the spiral and is sent powder and change into the powder feeding groove of a plurality of parallels and send powder, the utility model discloses the powder feeding volume of toner cartridge can be controlled by the quantity and the size of sending the powder groove, compares in the sponge mode of sending powder, and the powder feeding roller of this structure send the powder volume to obviously increase, also does not have too much surplus powder and remains.

The present invention will be further explained with reference to the drawings and examples.
Detailed Description
Referring to fig. 1 and 2, the toner cartridge has a toner hopper (not shown) for accommodating toner, a stirring frame 6 is disposed in the toner hopper, and a toner outlet 5 is formed at the bottom of the toner hopper. The sealing door 2 is supported in the toner hopper, the sealing door 2 can rotate along the axis of the sealing door 2 to control the opening and closing of the toner outlet 5, the sealing door 2 is provided with a semicircular tubular part 21 (see figure 4), and the semicircular tubular part 21 is provided with a box opening 211 corresponding to the toner outlet 5 along the axial direction of the sealing door 2. The sealing door 2 can control the alignment and the staggering of the box opening 211 and the powder outlet 5 through rotation, and when the box opening 211 is aligned with the powder outlet 5, the powder outlet 5 is opened; when the cartridge port 211 is staggered with the powder outlet 5, the powder outlet 5 is closed. That is, the sealing door 2 can control the opening and closing of the powder outlet 5 by rotating along the axis. A transmission part 4 is fixedly connected with the sealing door 2 in the circumferential direction, and the sealing door 2 can rotate along the axis of the sealing door under the driving of the transmission part 4. The outer surface of the semicircular tubular part 21 is an arc surface which is in close contact with the inner wall near the powder outlet 5 of the carbon powder bin. When the sealing door 2 rotates to a certain position, the cassette opening 211 is aligned with the toner outlet 5 of the toner cartridge, toner can reach the imaging component from the toner cartridge, and after the imaging component receives the toner supplied by the toner cartridge, the printing imaging process is completed through a series of operations such as developing, transfer printing, exposure imaging and the like. And when the sealing door 2 is in other positions, the powder outlet 5 is sealed, in order to prevent the carbon powder from leaking out from the space between the sealing door 2 and the inner wall of the carbon powder bin, a sealing sponge 7 is arranged between the sealing door 2 and the inner wall of the carbon powder bin, and other sealing elements can be selected as substitutes of the sealing sponge 7. The construction of the powder feed roller 1 is shown in fig. 3 and comprises two shaft ends 12, 13 and a roller 11 located between the two shaft ends. A plurality of powder feeding grooves 111 are uniformly arranged around the surface of the roller 11 in the axial direction. The roller 11 is partially housed in the above-mentioned semicircular tubular portion 21 above the powder outlet 211. The shaft end 13 of the powder feeding roller 1 is fixedly connected with the transmission shaft 3, and the powder feeding roller 1 can rotate relative to the sealing door 2 under the driving of the transmission shaft 3. The shaft end 12 of the powder feeding roller 1 extends into the shaft hole 22 on the sealing door 2, and the shaft end 12 is used as a support for the relative rotation of the powder feeding roller 1 and the sealing door 2. The notch of the powder feeding groove 111 is rectangular, the size of the notch corresponds to that of the box opening, and the length of the powder feeding groove 111 is equal to that of the box opening 211. When the sealing door 2 is opened, that is, the cartridge opening 211 and the powder outlet 5 are aligned, the carbon powder stirred up by the stirring frame 6 in the carbon powder bin falls onto the roller 11 of the powder feeding roller 1 along with the rotation of the powder feeding roller 1, the powder feeding groove 111 exposed out of the semicircular tubular part 21 on the roller 11 starts to collect and store the carbon powder, and when the powder feeding groove 111 storing the carbon powder rotates to the cartridge opening 211 (the powder outlet 5) of the sealing door 2, the carbon powder is completely poured out of the carbon powder bin, thereby completing the powder supply. The empty powder feeding groove is exposed out of the semi-circular tubular part 21 again, and then the next circulation process of collecting, storing, transporting and supplying powder is carried out.
Of course, the structural composition of the toner cartridge of the present invention is not limited to the above-described embodiments. For example, the powder feeding groove may have various shapes, such as a U shape, a V shape, etc., and the opening of the powder feeding groove may be slightly larger or smaller than the size of the cartridge opening. Obvious variations on the above-described embodiments, as well as other modifications, which do not depart from the gist of the invention, are intended to be within the scope of the appended claims.
