[0020] Please refer to Figures 1-4 It can be known that the utility model provides a kind of technical scheme: a carbon powder stirring structure with discharge dust structure, comprising: carbon powder warehouse main part 1, rotating shaft 2, drive motor 3, rotating roller 4, stirring rod 5 and developing roller 6, the inside of carbon powder warehouse main part 1 is connected with rotating shaft 2 by bearing, the front of carbon powder warehouse main part 1 is provided with drive motor 3, the output end of drive motor 3 is connected with one end of rotating shaft 2, the outside of rotating shaft 2 is connected with rotating roller 4, the outside of rotating roller 4 is connected with stirring rod 5, developing roller 6 is installed in the inside of carbon powder warehouse main part 1 close to stirring rod 5, collecting box 7 is installed between carbon powder warehouse main part 1 and drive motor 3, small dust fan 8 is installed in the front of collecting box 7, discharge port 9 is provided in the bottom of collecting box 7, conveying pipe 10 is connected between the inside of rotating roller 4 and the inside of collecting box 7, feed pipe 11 is connected to the outside of conveying pipe 10 close to rotating roller 4, through hole 12 is provided in the inside of stirring rod 5, carbon powder particle filter screen 13 is installed in the inside of stirring rod 5, three groups are provided at equal intervals in rotating roller 4 inside conveying pipe 10, plug-in structure is formed between feed pipe 11 and carbon powder particle filter screen 13.

[0021] In specific implementation, the carbon powder stirring structure is an important component inside the carbon powder tank main body 1, which can quickly stir and scatter the carbon powder agglomerates inside the carbon powder tank main body 1, thereby facilitating the subsequent use of the carbon powder. In the process of scattering the carbon powder, dust is easily generated inside the carbon powder tank main body 1, which is prone to leakage, thereby easily polluting the external environment. When the stirring rod 5 is running, the small dust suction fan 8 can be started. When the small dust suction fan 8 is running, suction can be generated inside the three groups of conveying pipes 10, and suction can also be generated at the end of the feeding pipe 11. When the carbon powder inside the carbon powder tank main body 1 is stirred, dust can be sucked into the carbon powder particle filter screen 13 through the through hole 12 by the suction of the feeding pipe 11. The carbon powder particle filter screen 13 can filter the carbon powder particles, so that the carbon powder particles are not easy to enter the inside of the carbon powder particle filter screen 13.

[0022] As shown in Figures 1-4 can be seen that the dust can enter the collection box 7 along the feeding pipe 11 and the conveying pipe 10, so that the dust generated inside the carbon powder tank main body 1 can be dusted by the small dust suction fan 8, so that the external environment is not easy to be polluted, and the dust inside the carbon powder tank main body 1 is not easy to leak.

[0024] In specific implementation, after the carbon powder stirring structure is used for a certain period of time, the stirring rod 5 needs to be disassembled and cleaned. The traditional stirring rod 5 and the rotating roller 4 are integrated, and the disassembly process of the rotating roller 4 is relatively cumbersome, which causes the disassembly of the stirring rod 5 to be relatively troublesome. The threaded pin 19 can be reversed, the end of the threaded pin 19 can threadedly slide away from the sliding block 18 when the threaded pin 19 is reversed, the sliding block 18 can be pulled away from the stirring rod 5 when the end of the threaded pin 19 no longer presses the sliding block 18, the sliding block 18 can be rotated through the connecting rod 17 when the sliding block 18 moves, the stirring rod 5 can be pulled away from the rotating roller 4 when the sliding block 18 is completely removed from the sliding groove 16, the stirring rod 5 can be disassembled from the rotating roller 4 when the stirring rod 5 moves and drives the butt joint block 14 to slide out of the sliding groove 16, and the disassembled stirring rod 5 can be cleaned at this time.

[0025] As shown in Figure 3 and Figure 4It can be known that the stirring rod 5 can be quickly disassembled without disassembling the rotating roller 4 through the above method.

[0026] In summary, when the stirring rod 5 is running, the small dust fan 8 can be started, and when the small dust fan 8 is running, suction can be generated inside the three groups of conveying pipes 10, and suction can also be generated at the end of the feeding pipe 11. Dust can enter the collecting box 7 along the feeding pipe 11 and the conveying pipe 10, so that the dust generated inside the carbon powder bin body 1 can be reduced by the small dust fan 8, so that the external environment is not easy to be polluted, and the dust inside the carbon powder bin body 1 is not easy to leak. When the stirring rod 5 moves, the abutting block 14 can be slid out of the sliding groove 16, so that the stirring rod 5 can be disassembled from the rotating roller 4. At this time, the disassembled stirring rod 5 can be cleaned. The stirring rod 5 can be quickly disassembled without disassembling the rotating roller 4 through the above method, and the contents not described in detail in the description belong to the prior art known to those skilled in the art.
