Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0019] Please refer to Figure 1 and Figure 2The utility model provides a technical scheme: a selenium drum facilitating adjusting the angle of powder scraping knife, which comprises a selenium drum main body 1, a toner bin 2, an imaging drum 3, a developing roller 4, a powder scraping knife main body 5 and a feeding opening 6, the inside of the selenium drum main body 1 is provided with the toner bin 2, the inside of the selenium drum main body 1 is respectively provided with the imaging drum 3 and the developing roller 4, the outside of the developing roller 4 is provided with the powder scraping knife main body 5, the top of the selenium drum main body 1 is provided with the feeding opening 6, the inside of the selenium drum main body 1 is provided with a connecting box 7 close to the developing roller 4, the inside of the connecting box 7 is connected with a lead screw 8 through a bearing, the outside of the lead screw 8 is connected with a moving block 9 in a screw thread mode, the outside of the moving block 9 is connected with a toothed plate 10, the inside of the connecting box 7 is provided with a connecting shaft 11, the outside of the connecting shaft 11 is rotatably connected with a connecting block 12, one end of the connecting block 12 close to the toothed plate 10 is connected with a half tooth 13, the other end of the connecting block 12 away from the half tooth 13 is connected with a fixed plate 14, the connecting block 12 and the connecting box 7 are connected with a small organ dust cover 15, the fixed plate 14 and the powder scraping knife main body 5 are fixed through screws, the toothed plate 10 and the half tooth 13 form a meshing structure, and the connecting block 12 and the connecting shaft 11 form a rotating structure.

[0020] In specific implementation, the selenium drum is a core component in a laser printer, the traditional powder scraping knife main body 5 is not easy to adjust the angle, so that the distance between the powder scraping knife main body 5 and the developing roller 4 is fixed, leading to the fact that the toner is prone to incomplete scraping or excessive scraping, thereby affecting the printing effect; when it is necessary to reduce the distance between the powder scraping knife main body 5 and the developing roller 4, the lead screw 8 can be positively rotated, when the lead screw 8 rotates, the moving block 9 can be driven to threadedly slide away from the developing roller 4, when the moving block 9 moves, the toothed plate 10 can be driven to move, when the toothed plate 10 moves, the half tooth 13 can be driven to move by meshing, when the half tooth 13 moves, the connecting block 12 can be driven to move, when the connecting block 12 moves, the connecting shaft 11 can be rotated, when the connecting block 12 rotates, the fixed plate 14 and the powder scraping knife main body 5 can be driven to move, and at the same time the connecting block 12 rotates, a group of small organ dust covers 15 can be compressed and another group of small organ dust covers 15 can be stretched, the small organ dust covers 15 can prevent the toner inside the toner bin 2 from entering the inside of the connecting box 7, when the powder scraping knife main body 5 moves, the bottom end thereof can move towards the developing roller 4, and when the powder scraping knife main body 5 moves to a specified position, the rotation of the lead screw 8 can be stopped.

[0021] Referring to Figure 1 and Figure 2 By adjusting the angle of the powder scraping knife main body 5, the distance between the powder scraping knife main body 5 and the developing roller 4 can be adjusted, so that the angle of the powder scraping knife main body 5 can be adjusted according to incomplete scraping or excessive scraping of the toner, and the subsequent printing effect is not prone to being affected.

[0022] Referring toFigure 1 and Figure 3 It can be seen that a feeding hopper 16 is provided above the feeding port 6, a connecting plate 17 is connected to the outside of the feeding hopper 16, a plastic plate 18 is connected to the bottom of the connecting plate 17, a plastic card block 19 is connected to the outside of the plastic plate 18, a fixing seat 20 is connected to the surface of the drum body 1 near the feeding port 6, a slot 21 matching the size of the plastic card block 19 is opened inside the fixing seat 20, and the surface of the plastic card block 19 is an arc surface.

[0023] In practice, when adding toner to the toner cartridge, the feeding port 6 needs to be opened. Due to the small size of the feeding port 6, toner is easily spilled when adding toner, which can easily contaminate the surface of the toner cartridge body 1 and cause material waste. After opening the feeding port 6, the feeding hopper 16 can be pushed towards the inside of the feeding port 6. When the bottom of the feeding hopper 16 moves into the inside of the feeding port 6, the connecting plate 17 on the outside of the feeding hopper 16 can drive the plastic plate 18 to be inserted into the fixing base 20. When the plastic plate 18 is inserted into the fixing base 20, the plastic locking block 19 will be squeezed by the fixing base 20, so that the two sets of plastic plates 18 can be squeezed towards each other. When the bottom of the plastic plate 18 slides to the deepest part of the fixing base 20, the plastic plate 18 can be reset. When the plastic plate 18 is reset, it can drive the plastic locking block 19 to engage with the locking slot 21, thereby installing the feeding hopper 16 on the top of the toner cartridge body 1. At this time, toner can be added to the feeding hopper 16 first.

[0024] See Figure 1 and Figure 3 It can be seen that the feeding hopper 16 can transport toner into the toner bin 2 through the feeding port 6. Since the top size of the feeding hopper 16 is larger than the feeding port 6, the toner is less likely to spill during the process of adding toner, so toner can be added into the toner bin 2 quickly, thus improving the efficiency of adding toner.

[0025] In summary, when using this toner cartridge with adjustable scraper angle, the lead screw 8 can be rotated forward. When the lead screw 8 rotates, it drives the moving block 9 to slide threaded away from the developing roller 4. By adjusting the angle of the scraper body 5, the distance between the scraper body 5 and the developing roller 4 can be adjusted. This allows for adjustment of the angle of the scraper body 5 based on whether the toner is scraped incompletely or excessively, thus minimizing the impact on subsequent printing results. The feeding hopper 16 delivers toner to the toner container 2 through the feeding port 6. Since the top size of the feeding hopper 16 is larger than the feeding port 6, toner is less likely to spill during the toner addition process, allowing for quick toner addition to the toner container 2 and improving toner addition efficiency. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0026] Although the utility model has been explained in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
