Description

Technical Field

[0001] This utility model relates to the field of printer toner cartridge technology, and more specifically, to a high-capacity printer toner cartridge. Background Technology

[0002] The printer drum is the core component of a laser printer, primarily responsible for transferring images and text onto paper. The basic structure of the drum consists of an aluminum substrate and a photosensitive material coated on it. The photosensitive drum, magnetic drum, and toner cartridge are integrated into one unit. During operation, the photosensitive drum carries a pre-charged charge. When light shines on it, the illuminated areas exhibit a resistance reaction. The transmitted data signal controls the laser emission, and the light scanning the surface of the photosensitive drum constantly changes. This results in some areas being illuminated, reducing resistance and eliminating charge, while other areas, unilluminated, retain the charge. Ultimately, a latent image composed of charge is formed on the surface of the drum.

[0003] Existing printer toner cartridges usually need to be shaken before installation to ensure even distribution of toner inside the cartridge and prevent toner from clumping. However, for high-capacity printer toner cartridges, the toner volume inside the cartridge is larger, requiring a longer shaking time and making it difficult to break up any clumped toner. This process is time-consuming, laborious, and does not easily achieve the goal of even toner distribution. Utility Model Content

[0027] Both the top of the fixing block 13 and the rotating block 14 are provided with a fitting groove 15. The locking blocks 23 at both ends of the fixing box 21 are inserted into the fitting groove 15 inside the rotating block 14 through the fitting groove 15 on the top of the fixing block 13. At this time, by rotating the fixing box 21, the locking blocks 23 drive the rotating block 14 to rotate, so that the fitting groove 15 of the rotating block 14 is misaligned with the fitting groove 15 of the fixing block 13, thereby limiting and fixing one end of the toner box 2.

[0028] like Figure 3 As shown, both ends of the fixed frame 18 are provided with movable slots 101. Movable blocks 103 are slidably installed inside the movable slots 101. Push blocks 102 are fixedly installed on one side of the movable blocks 103. A locking bolt 104 is fixedly installed on the side of the movable blocks 103 away from the push blocks 102. A locking spring 105 is fixedly installed on one side of the locking bolt 104. The locking spring 105 is located between the locking bolt 104 and the inner wall of the movable slots 101.

[0029] The snap-fit ​​block 23 is installed inside the rotating block 14 via the snap-fit ​​groove 15, the fixing box 21 is installed inside the placement groove 12, and the snap-fit ​​bolt 104 is installed inside the snap-fit ​​groove 24.

[0030] Push the push block 102 to both sides, so that the push block 102 drives the locking bolt 104 to move to both sides through the movable block 103, so that the locking spring 105 is compressed, and through the reaction force of the locking spring 105, the locking bolt 104 is embedded in the inside of the locking groove 24, thus completing the fixation of the toner cartridge 1 and the toner box 2, and fixing the toner box 2 inside the toner cartridge 1.

[0031] Example 2, as shown in the appendix Figure 4 To be continued Figure 6An embodiment of this utility model provides a high-capacity printer toner cartridge. The stirring assembly 25 includes two fixed sleeves 251 and stirring rods 253. The two fixed sleeves 251 are respectively fixedly installed on opposite sides of the fixed covers 22 at both ends. A rotating sleeve 252 is rotatably installed inside the fixed sleeve 251. The number of stirring rods 253 is several, and the several stirring rods 253 are evenly distributed on the outer surface of the rotating sleeve 252. Limiting blocks 254 are provided on both sides of the inner wall in the middle of the rotating sleeve 252. A fixed inner rod 255 is movably sleeved inside the rotating sleeve 252.

[0032] The inner rod 255 has a spiral groove 256 on its outer surface. The limiting block 254 is slidably installed inside the spiral groove 256. A pull rod 257 is fixedly installed on one side of the inner rod 255. A pull ring 258 is fixedly installed on one end of the pull rod 257. The pull rod 257 is movably sleeved inside the end cover 22. A return spring 259 is movably sleeved on the outer surface of the pull rod 257. The return spring 259 is located between the fixed sleeve 251 and the inner rod 255.

[0033] Since the rotating sleeve 252 rotates inside the fixed sleeve 251, and limit blocks 254 are provided on both sides of the inner wall of the middle part of the rotating sleeve 252, in conjunction with the stirring rod 253 on the outer surface of the fixed inner rod 255, when the pull ring 258 is pulled to move the fixed inner rod 255 to the left, the limit blocks 254 move along the spiral groove 256. Through the limitation of the spiral groove 256, the rotating sleeve 252 drives the stirring rod 253 on the outer surface to rotate inside the fixed box 21, and the stirring rod 253 stirs and breaks the toner inside the fixed box 21, which facilitates the breaking of toner without shaking the drum and avoids toner spillage. At the same time, the rotation of the stirring rod 253 makes the toner distribution inside the fixed box 21 more uniform.

[0034] The working process of this utility model is as follows:

[0035] Before installation, pull the ring 258 to move the fixed inner rod 255 to the left. When the fixed inner rod 255 moves to the left, the limiting block 254 moves along the spiral groove 256.

Through the reaction force of the return spring 259, the fixed inner rod 255 moves to the right inside the rotating sleeve 252. Through the spiral groove 256, the limiting block 254 moves and rotates along the spiral groove 256. This causes the rotating sleeve 252 to drive the stirring rod 253 to rotate in the opposite direction inside the fixed box 21. Using the limiting of the spiral groove 256, the rotating sleeve 252 drives the stirring rod 253 on the outer surface to rotate inside the fixed box 21. The stirring rod 253 stirs and breaks up the carbon powder inside the fixed box 21.

[0036] During installation, the locking blocks 23 at both ends of the fixing box 21 are inserted into the locking groove 15 at the top of the fixing block 13 and into the locking groove 15 inside the rotating block 14. At this time, by rotating the fixing box 21, the locking blocks 23 drive the rotating block 14 to rotate, causing the locking groove 15 of the rotating block 14 to be misaligned with the locking groove 15 of the fixing block 13, thereby limiting and fixing one end of the toner cartridge 2. Pushing the push block 102 to both sides causes the push block 102 to drive the locking bolt 104 to move to both sides through the movable block 103, compressing the locking spring 105. The fixing cover 22 falls into the placement groove 12, and the locking groove 24 moves to the side of the locking bolt 104. Through the reaction force of the locking spring 105, the locking bolt 104 is inserted into the inside of the locking groove 24, so that the toner cartridge 2 is fixedly installed inside the drum assembly 1.
