[0029] Example

[0030] The following is in conjunction with the appendix Figures 1-4 The first embodiment of this application will be described in further detail.

[0031] An installation method for a fixed cleaning device for toner cartridges is described in reference. Figure 1 ,include:

[0032] Placement platform 5;

[0033] Protective device, which is installed on the placement platform 5;

[0034] A vacuuming device is installed at the bottom of the placement platform 5;

[0035] A clamping and fixing device is provided on the placement platform 5;

[0036] Screw drive mechanism, the screw drive mechanism is installed on the protective device;

[0037] The gear transmission mechanism is located on one side of the screw transmission mechanism;

[0038] The toner cartridge unit is located on the placement platform 5.

[0039] Reference Figures 2-4The clamping and fixing device includes two push rod motors 13 and two clamping blocks 12. The two push rod motors 13 are both mounted on the placement platform 5, and the output shafts of the two push rod motors 13 are respectively fixedly connected to the two clamping blocks 12.

[0040] The screw drive mechanism includes a ball screw 10, a slider 9, and a cleaning cotton block 15. The ball screw 10 is rotatably connected to the dust cover 2. The ball screw 10 is threadedly connected to the slider 9, and the slider 9 is fixedly connected to the cleaning cotton block 15.

[0041] The gear transmission mechanism includes a forward and reverse motor 7, a first gear 16 and a second gear 17. A fixed plate 8 is fixedly connected to the dust cover 2. The forward and reverse motor 7 is mounted on the fixed plate 8. The output shaft of the forward and reverse motor 7 is fixedly connected to the first gear 16. The first gear 16 is fixedly connected to the ball screw 10. The first gear 16 meshes with the second gear 17.

[0042] The toner cartridge device includes a drum frame 11 and a drum core 18. The drum frame 11 is located on the placement platform 5, and the drum core 18 is rotatably connected to the drum frame 11. The second gear 17 is fixedly connected to the drum core 18.

[0043] The implementation principle of a fixing and cleaning device for toner cartridges according to an embodiment of this application is as follows: In use, the drum frame 11, drum core 18, and second gear 17 are placed on the placement platform 5. Two push rod motors 13 are activated, driving two clamping blocks 12 to move. The two clamping blocks 12 clamp and fix the drum frame 11 on both sides. Then, the dust cover 2 is rotated (which also rotates the dust collection pipe 1; the dust collection pipe 1 is made of rubber and its length is adjustable), causing the slot 4 to engage with the buckle 3, forming a sealed space. At this time, the first gear 16 and the second gear 17 mesh, and the forward and reverse rotation motor 7 is activated, rotating in both directions. Motor 7 drives the first gear 16 and ball screw 10 to rotate (the principle of ball screw 10: when the ball screw 10 rotates, the balls will roll inside the screw, thereby driving the slider 9 to move axially and achieve linear motion). The slider 9 drives the cleaning cotton block 15 to move. At the same time, the first gear 16 drives the second gear 17 to rotate, and the second gear 17 drives the drum core 18 to rotate, so that the cleaning cotton block 15 can clean multiple surfaces of the drum core 18. At the same time, the negative pressure fan 14 is started, which will create a negative pressure inside the dust collection box 6, thereby generating suction. The dust overflowing during the cleaning process is adsorbed through the dust collection pipe 1.

[0044] Example

[0045] The difference between this embodiment and Embodiment 1 is that a dust detector is installed on the dust cover 2, which can detect the particle content inside the dust cover 2, thereby adjusting the suction power of the negative pressure fan 14 and improving the dust collection efficiency.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
