Detailed implementation manners

[0024] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, as Figures 1 - 4 shown, a toner cartridge developing device for a printer includes a toner cartridge 100, a waste powder bin 200 and a photosensitive cartridge 300. The photosensitive cartridge 300 is located between the toner cartridge 100 and the waste powder bin 200. A horizontal plate 201 is fixedly installed horizontally inside the waste powder bin 200. A waste powder cleaning mechanism is provided above the horizontal plate 201. The waste powder cleaning mechanism includes a limiting sleeve 401 fixed to the upper end of the horizontal plate 201. A limiting plate 402 is provided in the limiting sleeve 401. The upper end of the limiting plate 402 is connected to the lower end surface of the interior of the limiting sleeve 401 through a first spring 403. A clamping groove 404 is provided at the lower end of the limiting plate 402. The limiting plate 402 is slidably connected to a cleaning blade 405. A groove 406 matching the clamping groove 404 is provided at the upper end of the cleaning blade 405. The first spring 403 applies a downward force to the limiting plate 402. By matching the clamping groove at the lower end of the limiting plate 402 with the groove at the upper end of the cleaning blade 405, the cleaning blade 405 is fixed, improving the stability of the cleaning blade 405.

[0026] In this embodiment, as Figure 2As shown, a photosensitive drum 301 is provided in the photosensitive chamber 300, and a photosensitive layer 302 is provided on the surface of the photosensitive drum 301. The photosensitive layer 302 on the surface of the photosensitive drum 301 contacts the bottom end of the cleaning scraper 405. A charging roller 303 is provided above the photosensitive drum 301. The charging roller 303 is fixed in a mounting groove 304. The mounting groove 304 is fixed to the upper surface inside the photosensitive chamber 300. The charging roller 303 is tangent to the photosensitive drum 301. When printing, the photosensitive drum 301 is charged by the charging roller 303, so that the surface of the photosensitive drum 301 absorbs toner for printing and development, and the cleaning scraper 405 scrapes off the residual toner on the surface of the photosensitive drum 301.

[0027] In one embodiment, Figure 2 As shown, a developing roller 101 is provided at the powder outlet of the toner cartridge 100, and the developing roller 101 is tangent to the photosensitive drum 301. The toner cartridge 100 is provided with a powder discharge knife 102, and the powder discharge knife 102 is located at the upper end of the developing roller 101. A sealing plug 103 is fixed at the lower end of the toner cartridge 100, and the sealing plug 103 is located at the lower end of the developing roller 101. The sealing plug 103 is in contact with the developing roller 101. A stirring member is provided in the toner cartridge 100, and the developing roller 101 is provided at the powder outlet of the toner cartridge 100 to absorb the toner. The powder discharge knife 102 at the upper end of the developing roller 101 scrapes the toner on the developing roller 101 evenly, and the sealing plug 103 at the lower end of the developing roller 101 prevents the toner in the toner cartridge 100 from leaking out from the lower end of the developing roller 101.

[0028] In one embodiment, Figure 2 and Figure 3 As shown, the stirring component includes a stirring shaft 501, and the stirring shaft 501 is rotatably connected to the inner cavity of the toner cartridge 100. Four baffles 502 are fixedly connected to the surface of the stirring shaft 501. The four baffles 502 are outerly connected to a baffle cover 503. A plurality of springs 504 are fixedly connected between the inner cavities of the baffles 502 and the baffle cover 503. The stirring shaft 501 rotates to drive the baffle 502 to rotate. The baffle cover 503 scrapes against the inner cavity wall of the toner cartridge 100 as the baffle 502 rotates, so that the accumulated toner is stirred up for use, thereby preventing toner from depositing and improving the utilization rate. A plurality of springs 504 are fixedly connected between the inner cavity of the baffle 502 and the baffle cover 503. When scraping against the inner cavity wall of the toner cartridge 100, the springs 504 shrink inwardly and return to their original positions when they are separated from the inner cavity wall of the toner cartridge 100.

[0029] In one embodiment, Figure 2As shown, an auxiliary cleaning blade 202 is further provided in the waste toner bin 200. The auxiliary cleaning blade 202 is located below the cleaning blade 405. The auxiliary cleaning blade 202 is fixedly connected to the waste toner bin 200 through a fixing plate 203. By adding the auxiliary cleaning blade 202, the residual toner on the surface of the photosensitive drum 301 can be better scraped clean, preventing toner residue from affecting the printing effect.

[0030] In one embodiment, as Figure 3 shown, the baffle plates 502 are evenly arranged on the surface of the stirring shaft 501, improving efficiency, enhancing stability and aesthetics.

[0031] In one embodiment, as Figure 1 and Figure 2 shown, a light-transmitting window 600 is provided at the upper end of the photosensitive cartridge 300. Through the light-transmitting window 600, a laser is irradiated onto the photosensitive drum 301, and the content to be printed is copied onto the photosensitive drum 301 for printing.

[0032] In one embodiment, as Figure 2 shown, a waste toner outlet 700 is provided at the lower end of the waste toner bin 200. A cover one 701 is rotatably connected outside the waste toner outlet 700. A powder inlet 800 is provided at the upper end of the toner cartridge 100. A cover two 801 is rotatably connected outside the powder inlet 800. By adding the waste toner outlet 700 and the powder inlet 800, it is convenient to clean the waste toner bin 200 and add toner to the toner cartridge 100.

[0033] The above embodiment discloses a printer toner cartridge developing device. The stirring shaft 501 rotates to drive the baffle plates 502 to rotate. The shielding cover 503 rubs against the inner cavity wall of the toner cartridge 100 as the baffle plates 502 rotate. This can not only evenly mix the toner in the cartridge but also stir up the accumulated toner for utilization, preventing toner deposition and improving utilization rate. A developing roller 101 is provided at the powder outlet of the toner cartridge 100 to adsorb toner. The powder scraping blade 102 at the upper end of the developing roller 101 scrapes the toner on the developing roller 101 evenly. The sealing plug 103 at the lower end of the developing roller 101 prevents the toner in the toner cartridge 100 from leaking out from the lower end of the developing roller 101. The charging roller 303 charges the photosensitive drum 301. The laser passes through the light-transmitting window 600 and irradiates onto the photosensitive drum 301, copying the content to be printed onto the photosensitive drum 301. The photosensitive drum 301 adsorbs the toner on the developing roller 101 for printing and developing. After printing, the cleaning blade 405 scrapes the residual toner on the surface of the photosensitive drum 301 clean. By adding the auxiliary cleaning blade 202, the residual toner on the surface of the photosensitive drum 301 can be better scraped clean, preventing toner residue from affecting the printing effect.

[0034] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
