Technical Field
[0001] This utility model relates to the field of printer toner cartridge technology, specifically a printer toner cartridge that can be quickly disassembled. Background Technology
[0002] A printer is a computer output device that can permanently output data stored in a computer as text or graphics onto paper or transparencies. There are many types of printers, and different types of printers have different functions, principles, and uses. The printer drum, also known as the photosensitive drum, is a key component in a laser printer, mainly responsible for the generation and transfer of images.
[0003] According to patent announcement CN217902257U, this printer toner cartridge with waste toner collection includes a printer toner cartridge shell and a drum core. An arc-shaped scraper is provided on one side of the drum core, and a control board is fixedly connected to the side of the arc-shaped scraper away from the drum core. Multiple push springs are fixedly connected between the control board and the printer toner cartridge shell. A pull cable is fixedly connected to one side of the control board, and a guide groove is provided at the bottom of the arc-shaped scraper. This printer toner cartridge with waste toner collection uses the arc-shaped scraper to scrape away waste toner from the outside of the drum core. The inclined arc-shaped scraper guides the scraped waste toner into the collection box for collection, which can quickly clean the waste toner from the outside of the drum core, ensuring the efficiency of the drum core's operation and improving the printer's overall efficiency. Furthermore, the pull cable allows adjustment of the contact force between the arc-shaped scraper and the drum core, ensuring efficient cleaning by the arc-shaped scraper.
[0004] However, in order to ensure the stability of the printer's operation, the printer drum needs to be maintained and repaired regularly during the use of the aforementioned patent. However, the drum core inside the printer drum is usually fixed by bolt connection. This fixing method is cumbersome to disassemble. It requires carrying special disassembly tools to repeatedly turn multiple sets of bolts to complete the disassembly of the drum core. Moreover, after maintenance, the above operation needs to be repeated to reinstall the drum core into the drum. It is time-consuming, laborious, and inconvenient, thus affecting the use of the printer drum. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-9This utility model provides a technical solution: a printer drum that can be quickly disassembled, including a drum shell 1, a drum core 2, and a limiting mechanism 5. The drum core 2 is disposed inside the drum shell 1, and support rods 3 are connected to both sides of the outer wall of the drum core 2. An end cap 4 is connected to one side of the outer wall of the drum shell 1. The limiting mechanism 5 includes a support base 501, a limiting block 502, a fixing plate 503, a guide seat 504, a spring 505, a fixing rod 506, a positioning block 507, a limiting component 508, a limiting pin 509, a slider 510, an extension block 511, and a fixing pin 512. The inner wall of the drum shell 1 has two... A support base 501 is welded to the side. A limit block 502 is fixedly connected to one side of the outer wall of the support rod 3. A fixing plate 503 is welded to the inner wall of the toner cartridge shell 1 near the support base 501. A guide seat 504 is slidably connected inside the fixing plate 503. A spring 505 is sleeved in the middle of the outer wall of the guide seat 504. A fixing rod 506 is welded to one side of the outer wall of the guide seat 504. A storage cavity is opened inside the support base 501, and the support rod 3 extends into it. A fixing hole is opened inside the support rod 3, and the fixing rod 506 extends into it. The support base 501 has a "U" shaped structure. The guide seat 504 has a "U" shaped structure. The structure is L-shaped. The spring 505 is connected to the fixing plate 503 and the fixing rod 506 on both sides respectively. The fixing plate 503, guide seat 504, spring 505, and fixing rod 506 form an elastic telescopic mechanism. A positioning block 507 is welded to one side of the outer wall of the end cover 4, and the positioning block 507 is distributed in a "U" shape. Limiting members 508 are connected to both sides of the outer wall of the toner cartridge shell 1, and the limiting members 508 have an L-shaped structure. Fixing cavities are opened on both sides of the outer wall of the end cover 4, and the limiting members 508 extend into them. A limiting pin 509 is connected inside the limiting member 508. The toner cartridge shell 1 is close to the limiting pin 509. A positioning hole is provided on one side of the positioning component 508, and a limiting pin 509 extends into it, and the limiting pin 509 is distributed in a "two" shape; a slider 510 is slidably connected inside the limiting component 508, and an extension block 511 is welded to the middle of the outer wall of the slider 510. A fixing pin 512 is connected to the bottom of the outer wall of the slider 510, and the fixing pin 512 is distributed in a "three" shape. A movable cavity corresponding to the slider 510 is provided inside the limiting component 508; the fixing plate 503 is symmetrically distributed about the vertical center line of the toner cartridge shell 1, and a mounting hole corresponding to the fixing pin 512 is provided inside the toner cartridge shell 1.
[0025] In practice, when the internal components of the toner cartridge 1 need to be inspected during the use of the printer toner cartridge, since the slider 510 is connected to the extension block 511 and the extension block 511 is connected to the fixing pin 512, the slider 510 is pushed first to move the extension block 511 upward. Then the extension block 511 moves upward to move the fixing pin 512 upward until the fixing pin 512 is disengaged from the toner cartridge 1, thereby canceling the fixation of the limiting member 508. Then the limiting member 508 is moved to disengage from the end cover 4, thereby canceling the limitation of the end cover 4. Then the end cover 4 is manually moved to disengage from the toner cartridge 1, so that the internal components of the toner cartridge 1 can be exposed. At this time, the internal components of the toner cartridge 1 can be maintained and inspected, which is convenient for subsequent installation, thus making it convenient for staff to inspect and disassemble the internal components of the toner cartridge.
[0026] When the drum core 2 needs to be disassembled for replacement, first manually move the guide seat 504 inside the fixing plate 503. Since the guide seat 504 is connected to the fixing rod 506, the movement of the guide seat 504 will drive the fixing rod 506 to move together. The movement of the fixing rod 506 will compress the spring 505, causing it to deform, until the fixing rod 506 is disengaged from the support rod 3, thereby releasing the fixation of the drum core 2. Then move the drum core 2 upward to disengage the support rod 3 from the support seat 501, so that the drum core 2 can be removed from the toner cartridge housing 1 for replacement. This eliminates the need to repeatedly turn multiple sets of bolts to complete the disassembly of the drum core 2, saving time and effort. This facilitates the inspection and disassembly of internal components when using the printer toner cartridge.
[0027] Because a limiting block 502 is connected to one side of the outer wall of the support rod 3, when the support rod 3 is placed inside the support base 501, the limiting block 502 and the support base 501 are engaged, thereby limiting the drum core 2. Then, the spring force generated by the spring 505 reset causes the fixing rod 506 to be inserted into the support rod 3, thereby fixing the drum core 2 and preventing it from moving at will, thus completing the installation of the drum core 2.
[0028] Because the end cap 4 is connected to the positioning block 507, when the end cap 4 is in contact with the outer wall of the drum housing 1, the positioning block 507 is in contact with the inner wall of the drum housing 1, thereby limiting the end cap 4. Since the inner wall of the limiting member 508 is connected to the limiting pin 509, when the limiting member 508 is moved and inserted into the end cap 4 and the drum housing 1 respectively, the limiting pin 509 is also inserted into the drum housing 1, thereby fixing the end cap 4 to prevent it from moving at will. Then, the extension block 511 is moved down to make the slider 510 move down until the fixing pin 512 is inserted into the drum housing 1, thereby fixing the limiting member 508 to prevent it from moving at will, thus completing the reset of the end cap 4.
[0029] In summary, when using this quick-detachable printer toner cartridge, the toner cartridge housing 1 is pre-installed in a designated position inside the printer. When the printer is working, the toner cartridge rotates with the machine, and the laser scans the toner cartridge housing 1, causing the photosensitive material on the surface of the housing to undergo charge shift, thereby forming a latent image. Then, through the drum core 2 and toner, the toner image is transferred to the paper during the transfer process, completing the printing. This is existing technology and will not be elaborated further here. The limiting mechanism 5 disengages the limiting member 508 from the end cover 4, thereby eliminating the connection between the ends. The cover 4 is positioned to limit the movement, and then the movable end cover 4 is disconnected from the drum housing 1, allowing the internal components of the drum housing 1 to be exposed for inspection; and the fixing rod 506 is disconnected from the support rod 3, thereby removing the fixation of the drum core 2. Then the drum core 2 is moved upward to disconnect the support rod 3 from the support base 501, so that the drum core 2 can be removed from the drum housing 1 for replacement. This eliminates the need to repeatedly turn multiple sets of bolts, thus completing the disassembly of the drum housing 1, saving time and effort. The contents not described in detail in this specification are prior art known to those skilled in the art.
[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
