[0020] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.
[0021] Example 1: Please refer to Figures 1 to 4A printer toner cartridge that can be injected with toner from the outside includes a toner cartridge body 1. A feeding box 2 is mounted on the top of the toner cartridge body 1 via a vertical bracket 3. One bottom end of the feeding box 2 is connected to the top inlet end of the toner cartridge body 1 via a feeding tube 4. A protective box 9 is installed on the outer wall of the end of the feeding box 2 closest to the feeding tube 4. A movable rod 10 is inserted and connected to the end of the protective box 9 furthest from the feeding box 2. One end of the movable rod 10 is placed inside the protective box 9 and connected to one side of a connecting plate 12. The other side of the connecting plate 12 is connected to one end of a sealing plate 13. The bottom of the side end of the feeding box 2 is provided with... A slot 8 is provided, and the sealing plate 13 is inserted and fitted into the slot 8. The bottom end of the sealing plate 13 is slidably fitted to the top end of the feeding tube 4. The end of the sealing plate 13 away from the pull ring 11 has an inclined end face, which makes it easy to insert the end into the toner, so that the movement of the sealing plate 13 is not obstructed. The length of the protective box 9 is sufficient to meet the movement requirements of the sealing plate 13. A first triangular plate 14 is provided on the inner wall of the end of the feeding box 2 near the feeding tube 4, and a second triangular plate 15 is provided on the top end of the feeding box 2. The first triangular plate 14 and the second triangular plate 15 are respectively placed on both sides of the feeding tube 4.
[0022] Please see Figure 1 , Figure 2 The feeding box 2 is equipped with a rotating rod 18, which is positioned above the second triangular plate 15. A spiral conveying blade 19 is mounted on the outer wall of the rotating rod 18. A driving component 17 is mounted on the outer wall of the other end of the feeding box 2 via a mounting sleeve 16. The output end of the driving component 17 is connected to one end of the rotating rod 18. In this embodiment, a bracket 20 is mounted on the inner bottom surface of the feeding box 2, and a support plate 21 is mounted on the top of the bracket 20. The support plate 21 is semi-circular and cylindrical, used to improve the stability of the rotating rod 18 and to support the bottom of the other end of the rotating rod 18.
[0023] Example 2: See Figure 1 , Figure 3 Based on Embodiment 1, the output end of the drive component 17 is equipped with an output shaft 22. The output shaft 22 and the rotating rod 18 are provided with stepped grooves 23 that mate with each other at their respective ends. The output shaft 22 and the rotating rod 18 are connected and fixed by a second bolt 24, which facilitates the disassembly and assembly of the drive component 17. The drive component 17 is selected as a drive motor and is connected to an external control circuit.
[0024] Please see Figure 1The top two sides of the feeding box 2 are connected to mounting plates 6. The top of the feeding box 2 is detachably mounted with a top cover plate 5. The two ends of the top cover plate 5 are respectively mounted on the two mounting plates 6 by first bolts 7, so as to facilitate the internal inspection and addition of toner in the feeding box 2.
[0025] Working principle: When in use, add an appropriate amount of toner to the feeding box 2, and then install the top cover plate 5. When the toner box body 1 needs to be replenished with toner, pull the pull ring 11 to move the movable rod 10, which in turn moves the sealing plate 13. When the sealing plate 13 moves to the point where it no longer seals the top of the feeding tube 4, the toner can be replenished into the toner box body 1 through the feeding tube 4. The drive component 17 drives the rotating rod 18 to rotate, which in turn drives the spiral conveyor blade 19 to rotate to transport the toner. With the help of the first triangular plate 14 and the second triangular plate 15 for guidance, the toner is collected at the top of the feeding tube 4. After the toner is replenished, move the sealing plate 13 to seal the top of the feeding tube 4.
