SPECIFIC IMPLEMENTATION

[0021] In order to make the technical means, creation features, reach the purpose and the easy understanding of efficacy of the utility model, the following specific implementation is combined, and the utility model is further expounded.

[0022] Embodiment one, such as Figures 1-5As shown, a toner cartridge structure for a laser printer includes a new toner cartridge 1. A cover plate 2 is provided above the new toner cartridge 1. The new toner cartridge 1 is sealed by the cover plate 2 and the sealing strip 3. The sealing cover above the toner inlet 5 is unscrewed to add toner into the new toner cartridge 1. A limiting block 6 is provided to facilitate the operator to fix the toner cartridge body inside the printer. The transmission gear 9 is connected to the drive device inside the printer so that it is close to the imaging drum inside the toner cartridge. When the paper passes between the transfer roller and the imaging drum, it drives the imaging drum to rotate, thereby driving the developing roller 18 to rotate. During the rotation of the developing roller 18, the toner inside the new toner cartridge 1 is adsorbed onto its surface. The toner feeding blade 15 is provided to make the toner evenly spread on the surface of the developing roller 18.

[0023] Example 2, as Figures 1-5 As shown, a toner cartridge structure for a laser printer is described. During rotation, the developing roller 18 delivers toner from its surface to the surface of the imaging drum. As the imaging drum rotates, it prints toner onto the paper surface. After the imaging drum prints toner onto the paper surface, a cleaning scraper 23 cleans the residual toner on the surface of the imaging drum. The scraped-off toner is collected into the waste toner cartridge 7 by a second baffle 22. The waste toner is easily discharged by the operator through the toner outlet 8. The first mounting base 12 facilitates the installation and removal of the toner feeding blade 15, and the second baffle 22 facilitates the installation and removal of the cleaning scraper 23.

[0024] It should be noted that this utility model is a toner cartridge structure for a laser printer. When the operator needs to assemble the toner cartridge, firstly, the toner delivery blade 15 is installed on the front outer surface of the first mounting base 12 using the fixing screw 17. Then, the positioning post 19 at the left end of the developing roller 18 is inserted into the limiting groove 11, so that a gap is maintained between the developing roller 18 and the toner delivery blade 15 to allow toner delivery. The transmission gear 9 is placed on the right side of the new toner cartridge 1, and the transmission gear 9 is connected to the left end of the developing roller 18 using the connecting bolt 20. Then, the waste toner cartridge 7 is connected to the new toner cartridge 1, so that the waste toner cartridge 7 is at the front end of the imaging drum. The cleaning scraper 23 is fixed on the front outer surface of the second mounting base 21 using the fixing screw 17, so that the cleaning scraper 23 contacts the surface of the imaging drum. Then, the toner cartridge is installed inside the printer, and the toner cartridge is limited by the limiting block 6.
