Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a structure for preventing misalignment of printer consumables. Background Art

[0002] The toner cartridge is a very important consumable part of the laser printer, and its internal structure has a direct impact on the printing quality and printing effect.

[0003] The drum core is the core of the toner cartridge. It consists of a metal cylinder with a layer of photosensitive material coated on its surface, usually selenium, cadmium sulfide or other photosensitive semiconductor materials. During the printing process, the drum core rotates and forms a pattern under the action of the laser. This pattern is then transferred to the paper by the toner. Before printing, the charging roller charges the drum core to make the drum surface statically charged. This ensures that when the laser is irradiated, only the specified part will lose the charge, thus forming the pattern. The cleaning scraper is used to remove the residual toner left on the drum core after printing, so that it can be used for the next print.

[0004] A printer toner cartridge is disclosed in Chinese patent publication number CN216927376U. The printer toner cartridge has a waste toner box with a drum core, a developing roller at the bottom of the toner box, the developing roller and the drum core are arranged parallel and spaced apart, and both are rotatably connected to the end cover.

[0005] However, compared with the existing technologies in the related fields, after long-term use, the drum core will have certain wear and tear after long-term electric charge and waste powder recovery by the scraper, so it is necessary to replace the drum core regularly. However, when replacing the existing drum core, it is necessary to remove the side panel screws of multiple toner cartridges, which makes the replacement process more cumbersome. At the same time, during the replacement process, in order to ensure that the drum core is installed in the specified position, the user needs to constantly adjust the position of the drum core. Once the position of the drum core deviates, printing abnormalities and other problems are likely to occur. In addition, when replacing, the user may touch the outer surface of the drum core, causing impurities to adhere to the surface of the drum core, which is also prone to printing abnormalities and other problems.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0026] Additional aspects and advantages of the present invention will be further described below in conjunction with the accompanying drawings, and some will become apparent from the following description or be learned through practice of the present invention.

[0027] like Figures 1 to 6 As shown, the structure for preventing misalignment of printer consumables includes a printer cartridge body 1, a drum core 2 is installed on one side of the printer cartridge body 1, a driving member 3 is provided on one side of the printer cartridge body 1 located at the drum core 2, and an anti-misalignment mechanism 4 is provided on the other end of the printer cartridge body 1 located at the drum core 2; the anti-misalignment mechanism 4 includes a baffle 401 which is slidably matched with the printer cartridge body 1, a rotating unit 5 which is rotatably matched with the drum core 2 is provided on the baffle 401, an insert block 402 is slidably provided inside the baffle 401, and a slot 101 is provided on one end of the printer cartridge body 1 located at the insert block 402.

[0028] like Figure 2 , Figure 4 and Figure 6 As shown, a connecting shaft 301 is fixedly provided at the output end of the driving member 3, and a connecting hole is provided at a position of the drum core 2 corresponding to the connecting shaft 301. The cross-sectional shape of the connecting shaft 301 is hexagonal, and a chamfered surface is formed at one end of the connecting shaft 301 away from the driving member 3. The chamfered surface can facilitate the quick docking of the drum core 2 and the connecting shaft 301, and the output end of the driving member 3 can control the rotation of the drum core 2 through the connecting shaft 301.

[0029] like Figure 2 , Figure 5 and Figure 6 As shown, the baffle 401 is slidably matched with the printer drum body 1 through the sliding shaft 403. There are two sliding shafts 403. The printer drum body 1 is provided with sliding holes 102 at positions corresponding to the two sliding shafts 403. The sliding shaft 403 and the sliding hole 102 are matched and connected by an elastic member 404. When the drum core 2 and the connecting shaft 301 are connected, the baffle 401 is pressed so that the sliding shaft 403 compresses the elastic member 404. After the plug 402 is separated from the slot 101, the potential energy of the elastic member 404 is automatically released, and then the sliding shaft 403 is pushed by the elastic member 404, so that the rotating unit 5 on the baffle 401 is separated from the drum core 2.

[0030] like Figure 5As shown, the rotating unit 5 includes a rotating disk 501 rotatably connected to the baffle 401, and a docking shaft 502 is fixedly arranged at the center of the rotating disk 501. The docking shaft 502 is in the shape of a cylinder, and a chamfered surface is formed at the end of the docking shaft 502. A rotating groove is provided at the position of the baffle 401 corresponding to the rotating disk 501, and the rotating disk 501 is connected to the rotating groove through a bearing. By using the above-mentioned bearing, the friction force when the rotating disk 501 rotates can be reduced, and the stability of the rotating disk 501 when rotating can be improved.

[0031] like Figure 4 and Figure 5 As shown, the shape of the plug block 402 is L-shaped, and a movable groove 4011 is opened at the position of the baffle 401 corresponding to the plug block 402. The end of the plug block 402 away from the slot 101 is formed with a slope, so that the user can easily control the plug block 402 to separate from the slot 101.

[0032] The working process is as follows:

[0033] S1, such as Figures 1 to 4 As shown, when the drum core 2 needs to be replaced, the printer drum body 1 is separated from the printer, and then the plug-in block 402 is pulled out, so that the plug-in block 402 is separated from the slot 101;

[0034] S2, such as Figures 2 to 5 As shown, when the insert block 402 is separated from the slot 101, the potential energy of the elastic member 404 is automatically released, and then the elastic member 404 pushes the sliding shaft 403, so that the rotating unit 5 on the baffle 401 is separated from the drum core 2;

[0035] S3, such as Figures 2 to 6 As shown, after the rotating unit 5 is separated from the drum core 2, the old drum core 2 can be removed, and the new drum core 2 can be docked with the driving member 3 on the printer drum body 1 for installation. During docking installation, the connecting hole of the drum core 2 is docked with the connecting shaft 301. At this time, the chamfered surface at the end of the connecting shaft 301 can be used to facilitate the quick docking of the drum core 2 and the connecting shaft 301 (such as Figures 2 to 4 As shown, during installation, the printer drum body 1 can be placed vertically, and the end of the drum core 2 can be controlled to dock with the connecting shaft 301);

[0036] S4, such as Figures 1 to 5 As shown, after the drum core 2 and the connecting shaft 301 are connected, the baffle 401 is pressed to make the sliding shaft 403 compress the elastic member 404. When the insert block 402 is aligned with the slot 101, the insert block 402 is controlled to be inserted into the slot 101, and then the insert block 402 cooperates with the slot 101 to limit the baffle 401.

[0037] S5. When the baffle 401 is limited, the docking shaft 502 is just inserted into the hole at the end of the drum core 2. At this time, the turntable 501 will fit with the end of the drum core 2, thereby ensuring the correct installation of the drum core 2 and avoiding the problem of misaligned installation of the drum core 2.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
