Description

Technical Field

[0001] The utility model belongs to the technical field of printing equipment, in particular to a toner cartridge. Background Art

[0002] A toner cartridge is a device that converts electronic signals into images. It usually includes a photosensitive drum and a charging component. Its main function is to receive print data and transfer the image or text to paper through electrostatic imaging technology. The photosensitive drum is the core part of the toner cartridge. The surface is coated with photosensitive material to form an electrostatic latent image. The charging component applies charge to the photosensitive drum, and the cleaning knife removes residual toner on the photosensitive drum to ensure print quality.

[0003] After the existing photosensitive drum is evenly charged by the charger, the laser beam scans the photosensitive drum to form a latent image of the image or text information to be printed in an electrostatic manner, and the toner is adsorbed on the electrostatic latent image to form an actual image or text. The toner image is transferred from the photosensitive drum to the paper, and the toner is melted and fixed on the paper by heating and pressure. The remaining toner on the photosensitive drum is scraped off by a cleaning knife to prepare for the next round of printing. However, the cleaning knife is usually made of rubber, and the excess toner on the photosensitive drum has a high temperature and will stick to each other. After long-term use, the toner will agglomerate and adhere to the surface of the cleaning knife, scratching the surface of the photosensitive drum while it rotates, causing blurred paper fixing. Professional maintenance personnel are required to disassemble the toner cartridge to clean the cleaning knife, which is very inconvenient to use and is not conducive to the reuse of the toner cartridge.

[0004] Therefore, we provide a toner cartridge to solve the above problems. Utility Model Content

The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Specific embodiment 1

[0032] See also Figure 1-8 The utility model is a toner cartridge, comprising a shell 1, with cover plates 2 installed on both sides of the shell 1, a drum core 3 installed inside the shell 1, a charging roller 4 installed on the top of the drum core 3, and a magnetic roller 5 installed on the rear side of the drum core 3;

[0033] A cleaning assembly is arranged inside the housing 1, and the cleaning assembly includes a cleaning scraper 6, which is arranged on the top of the drum core 3, a metal plate 7 is fixedly connected to the top of the cleaning scraper 6, and a fixing column 8 is fixedly connected to the top of the metal plate 7;

[0034] A fixing assembly is disposed on one side of the housing 1 , and the fixing assembly includes a limit plate 9 . The limit plate 9 is disposed on one side of the cover plate 2 , and a fixing screw 10 is disposed on one side of the limit plate 9 .

[0035] Specifically: the shell 1 is internally installed with components such as a drum core 3, a charging roller 4 and a magnetic roller 5, which is a mature design in the prior art and can cooperate with the printing equipment to complete the printing of paper. The fixed column 8 is a cylindrical design. The length of the metal plate 7 is the same as that of the cleaning scraper 6, which can support the cleaning scraper 6. The limit plate 9, the metal plate 7 and the baffle 14 are all fixed to the surface of the fixed column 8. The limit plate 9 and the metal plate 7 keep the horizontal position consistent. A screw hole is opened on one side of the shell 1. The fixing screw 10 passes through the limit plate 9 and is threadedly connected to the screw hole to fix the position of the fixed column 8. Specific embodiment 2

[0037] See also Figure 1-8 On the basis of the specific embodiment 1, a circular shell 11 is sleeved on the surface of the fixed column 8, a bracket 12 is fixedly connected to the top of the circular shell 11, and the top of the bracket 12 is fixedly connected to the inner wall of the shell 1, a through hole 13 is opened on one side of the cover plate 2, and the size of the through hole 13 is the same as the vertical cross-sectional size of the metal plate 7, the fixed column 8 and the cleaning scraper 6, one end of the fixed column 8 penetrates to the outside of the cover plate 2 and is fixedly connected to the limit plate 9, one end of the fixed screw 10 penetrates the limit plate 9 and is threadedly connected to the cover plate 2, a baffle 14 is fixedly connected to the surface of the fixed column 8 and located outside the cover plate 2, the size of the baffle 14 is larger than the size of the through hole 13, a limited column 15 is fixedly connected to one side of the cover plate 2 and located in front of the baffle 14, the cleaning scraper 6 is made of polyurethane, a block 16 is fixedly connected to one side of the cover plate 2, and a cleaning groove 17 is opened inside the block 16, a movable shell 18 is fixedly connected to the top of the shell 1, and a chip shell 19 is installed on the front side of the shell 1.

[0038] Specifically: a slot is provided at the bottom of the circular shell 11, and the diameter of the slot is smaller than the diameter of the fixing column 8, so that when the fixing column 8 is inserted into the circular shell 11, it can play a supporting role, and at the same time will not limit the rotation of the fixing column 8. When the fixing column 8 is inserted into the circular shell 11, it can also drive the metal plate 7 to rotate left and right in the slot. The size of the through-port 13 is the same as the vertical cross-sectional size of the metal plate 7, the fixing column 8 and the cleaning scraper 6. When the metal plate 7 rotates and aligns with the through-port 13, the metal plate 7 and the cleaning scraper 6 can be pulled to the right to completely separate the cleaning scraper 6 from the cover plate 2 and the baffle 14. The size is larger than that of the through opening 13. After the cleaning scraper 6 is completely fixed, the through opening 13 can be covered to maintain the sealing between the cover plate 2 and the shell 1. The cleaning scraper 6 is made of polyurethane. Polyurethane is a commonly used elastomeric material with good wear resistance and flexibility. It can effectively adhere to the surface of the photosensitive drum and remove residual toner without damaging the photosensitive drum. A cleaning groove 17 is provided inside the card block 16. When the cleaning scraper 6 is taken out, the cleaning scraper 6 can be inserted into the cleaning groove 17 and moved up and down to clean the toner blocks on the surface of the cleaning scraper 6.

[0039] The working principle of the utility model is as follows: when the text printed by the printing device appears blurred, the staff can take the toner cartridge out of the printer and observe the drum core 3. When slight scratches appear on the surface of the drum core 3, the staff can manually rotate and remove the fixing screw 10 to cancel the limit of the limit plate 9, and then rotate the limit plate 9 clockwise, and the limit plate 9 cooperates with the fixed column 8 to drive the baffle 14 to rotate. When the baffle 14 contacts the limit column 15, the cleaning scraper 6 and the metal plate 7 will maintain a horizontal position with the through opening 13, and then pull the limit plate 9 to the right, and the limit plate 9 cooperates with the fixed column 8 to drive the metal plate 7 and the cleaning scraper 6 to move, so that the cleaning scraper 6 is completely separated from the cover plate 2;

[0040] The staff observes whether there is carbon powder caking or damage on the surface of the cleaning scraper 6. When there is carbon powder remaining on the surface of the cleaning scraper 6, the cleaning scraper 6 can be inserted into the cleaning groove 17 inside the block 16 and moved up and down to clean the carbon powder blocks on the surface of the cleaning scraper 6. After cleaning, the cleaning scraper 6 is inserted into the shell 1 again, and the limit plate 9 is rotated counterclockwise. The limit plate 9 cooperates with the fixed column 8 to drive the cleaning scraper 6 to contact the drum core 3; the entire maintenance process does not require the entire shell 1 to be disassembled, so that personnel without maintenance experience can also easily clean, thereby improving the practical effect.
