Description

Technical Field

[0001] This utility model specifically relates to an adjustable toner cartridge replenishment device, belonging to the field of toner cartridge replenishment technology. Background Technology

[0002] A toner refill device is a device used to replenish toner cartridges in laser printers, electrostatic copiers, and other equipment, in order to extend the life of the toner cartridge and avoid the waste of resources and environmental pollution caused by discarding the entire toner cartridge when the toner runs out.

[0003] Currently, when refilling toner cartridges, the small diameter of the cartridge filling port and the significantly smaller discharge port of the toner bottle compared to the bottle diameter create negative pressure inside the bottle during the toner dispensing process, resulting in flow resistance. This causes toner to accumulate and clog at the nozzle and the cartridge filling tube, making it difficult for toner to smoothly enter the cartridge and increasing the time and difficulty of toner refilling. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an adjustable toner cartridge replenishment device.

[0005] An adjustable toner cartridge refill device includes a drum body and a toner box. The drum body has a feed inlet, and the bottom of the toner box has a discharge port for inserting into the feed inlet to replenish toner into the drum body. A mounting sleeve is fixedly connected to the top of the inside of the toner box. A rotating rod rotatably passes through the inside of the toner box, with one end of the rotating rod passing through the inside of the mounting sleeve and a torsion spring between the rotating rod and the sleeve. Multiple sets of stirring rods are fixedly fixed at equal intervals in the area of ​​the rotating rod inside the toner box. A rope is fixedly connected to one end of the stirring rod, and a striking ball is fixedly connected to one end of the rope. A rotating block is fixedly connected to the end of the rotating rod outside the toner box.

[0006] A square slide rod runs through the inside of the rotating rod. A pull rod is fixed to one end of the square slide rod at the top of the toner box. A groove for the pull rod to slide is opened on one side of the rotating rod. A bolt rod is installed at the top of the rotating rod. A strong magnetic plate is fixed to the middle of the rotating rod. A strong magnetic plate that attracts the pull rod is also provided on one side of the pull rod. A stirring blade is fixed to one end of the square slide rod at the bottom of the toner box.

[0007] A baffle is fixedly connected to one end of the stirring blade, and the end of the baffle connected to the stirring blade is elliptical. A sealing ring is fixedly connected to the inner side of the discharge port.

[0008] A support ring is fixed to the outer wall of the discharge port, and a sealing plate is slidably connected to the outer wall of the discharge port. One end of the sealing plate is filled with gel, and multiple sets of springs are arranged around the support ring and the sealing plate.

[0009] An observation window is provided on one side of the toner box, and the observation window is transparent.

[0010] A handle is installed on one side of the outer wall of the toner box, and the handle is provided with anti-slip texture.

[0011] Beneficial effects:

[0012] After positioning the toner cartridge by the handle and locking the lever position via a strong magnetic plate, the square sliding rod pushes the stirring blade into the drum, causing it to move and disengage the discharge port, automatically opening it for toner replenishment. Then, the rotating block drives the stirring rod, stirring blade, and striking ball to work together. During this process, the rotation of the stirring rod and blade effectively prevents toner clumping and blockage, ensuring good toner flowability. Meanwhile, the rope-connected striking ball periodically strikes the inner wall of the toner cartridge under centrifugal force, dislodging adhering toner and reducing the risk of discharge port blockage. Simultaneously, the torsion spring's energy storage and release cycle allows it to release energy after the rotating block is released, driving the rotating block in the opposite direction. The rotating rod and its associated stirring rod and blades further enhance the turbulence and anti-clogging effects, achieving efficient and clog-free toner delivery. After replenishment, pulling the rod and fixing one end of the rod to the other end of the rotating rod with bolts causes the stirring blades and square sliding rod to move with the rod. The stirring blades retract into the toner box for automatic and complete storage. Simultaneously, the baffle re-enters the discharge port and makes tight contact with the sealing ring, automatically closing the discharge channel to prevent toner leakage, reduce waste and environmental pollution. In summary, this achieves flexible adjustment of the stirring blade position, efficient stirring and anti-clogging, and automatic sealing of the discharge port, ensuring the efficiency, reliability, and environmental friendliness of the toner replenishment process, while improving user experience and ease of operation.

[0019] 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.

[0020] Please see Figures 1-5 As shown, an adjustable toner cartridge refill device includes a drum body 1 and a toner cartridge 2. The drum body 1 has a feed inlet 3. The bottom of the toner cartridge 2 is equipped with a discharge port 4 for inserting into the feed inlet 3 to replenish toner into the drum body 1. A mounting sleeve 6 is fixedly connected to the top of the inside of the toner cartridge 2. A rotating rod 5 rotatably passes through the inside of the toner cartridge 2, and one end of the rotating rod 5 passes through the inside of the mounting sleeve 6 and is connected to the sleeve with a torsion spring 7. Multiple sets of stirring rods 8 are fixedly fixed at equal intervals in the area of ​​the rotating rod 5 inside the toner cartridge 2. A rope 9 is fixedly connected to one end of the stirring rod 8, and a striking ball 10 is fixedly connected to one end of the rope 9. A rotating block 11 is fixedly connected to the end of the rotating rod 5 outside the toner cartridge 2. The drum body 1 is the main part of the toner cartridge, used to contain and store toner and perform printing or copying operations. The toner cartridge 2 is used to store toner to be replenished. The discharge port 4 at its bottom can be inserted into the feed inlet 3 of the drum body 1 to replenish toner. On the drum body 1, the discharge port 4 serves as the channel for toner to enter the drum body 1, guiding the toner from the toner box 2 into the drum body 1. Rotating the rotating rod 5 drives the stirring rod 8 to stir, preventing toner from clumping or clogging in the toner box 2. The mounting sleeve 6 supports and fixes the rotating rod 5. The torsion spring 7 stores energy when the rotating rod 5 rotates; when the rotating rod 5 is released, the torsion spring 7 releases the energy, causing the rotating rod 5 to rotate in the opposite direction, achieving automatic reverse stirring and turbulence. The stirring rod 8 stirs the toner, breaking up toner clumps and clogging the discharge port 4 during rotation, ensuring powder flowability and preventing clogging due to negative pressure. The rope 9 connects to the striking ball 10, which generates centrifugal force when the rotating rod 5 rotates, periodically striking the inner wall of the toner box 2 to dislodge adhering powder, further reducing clogging at the discharge port 4. The rotating block 11 allows the user to manually rotate the rotating rod 5, thus achieving stirring and striking actions.

[0021] Furthermore, a square slide rod 12 runs through the inside of the rotating rod 5. A pull rod 14 is fixedly connected to one end of the square slide rod 12 at the top of the toner box 2. A groove for the pull rod 14 to slide is provided on one side of the rotating rod 5. A bolt rod 15 is installed at the top of the rotating rod 5. A strong magnetic plate 13 is fixedly connected to the middle of the rotating rod 5. A strong magnetic plate 13 is also provided on one side of the pull rod 14 to attract it. A stirring blade 16 is fixedly connected to one end of the square slide rod 12 at the bottom of the toner box 2. The square slide rod 12 can slide along the axial direction of the rotating rod 5 to adjust the position of the stirring blade 16, so as to facilitate the insertion of the stirring blade 16 into the drum 1 and the feed inlet. Inside the drum 1, the pull rod 14 allows personnel to easily pull the square slide rod 12 up and down. The slide groove ensures that the pull rod 14 can smoothly drive the square slide rod 12 to move. The bolt rod 15 is used to lock the position of the pull rod 14 to prevent it from sliding accidentally. The two sets of strong magnetic plates 13 use the magnetic attraction property to quickly lock the position of the pull rod 14 when the stirring blade 16 is inserted into the drum 1. One end of the stirring blade 16 is used to insert into the drum 1 and the feed inlet 3, and the end of it close to the pull rod 14 is also located inside the feed inlet 3, for stirring and turbulence inside the feed inlet 3, the drum 1 and the feed inlet 3.

[0022] Furthermore, a baffle 17 is fixedly connected to one end of the stirring blade 16. The end of the baffle 17 connected to the stirring blade 16 is elliptical. A sealing ring 18 is fixedly connected to the inner side of the discharge port 4. The baffle 17 is the valve for opening and closing the discharge port 4. Its elliptical shape is used to prevent carbon powder from accumulating. The sealing ring 18 is used to improve the sealing effect between the baffle 17 and the discharge port 4.

[0023] Furthermore, a support ring 19 is fixedly connected to the outer wall of the discharge port 4, and a sealing plate 21 is slidably connected to the outer wall of the discharge port 4. One end of the sealing plate 21 is filled with gel, and multiple sets of springs 20 are arranged around the support ring 19 and the sealing plate 21. The support ring 19 serves as the support base for the multiple sets of springs 20. Under the elastic thrust of the springs 20, the sealing plate 21 is tightly pressed against the feed port 3 to prevent some toner from leaking out through the gap when the feed port 3 is larger than the discharge port 4. The sealing and deformation effects of the gel further improve the sealing effect on the feed port 3. The springs 20 provide elastic force to continuously push the sealing plate 21 against the feed port 3.

[0024] Furthermore, an observation window 22 is provided on one side of the toner box 2. The observation window 22 is transparent. The observation window 22 allows direct viewing of the remaining toner level inside the toner box 2 without opening the toner box 2 or performing other complicated operations.

[0025] Furthermore, a handle is installed on one side of the outer wall of the toner cartridge 2, and the handle has anti-slip texture; the design of the handle allows the user to easily hold the toner cartridge 2, which is convenient for handling and filling operations, while the anti-slip texture provides better grip and prevents slippage due to sweaty hands or other reasons during handling or filling operations.

[0026] Operating Steps: First, the user easily moves the toner cartridge 2 to the vicinity of the printer using the handle on one side of the outer wall. The user aligns the discharge port 4 with and inserts it into the feed port 3 on the drum body 1 to prepare for toner replenishment. Then, loosen the bolt rod 15 to disengage it from the pull rod 14, allowing adjustment of the position of the stirring blade 16. Pushing the pull rod 14 causes the strong magnetic plate 13 at one end of the pull rod 14 to attract the strong magnetic plate 13 on the rotating rod 5. This action moves the square sliding rod 12 and the stirring blade 16 together. The baffle 17 disengages from the discharge port 4 as the stirring blade 16 moves, opening the discharge port 4 to prepare for toner replenishment. Simultaneously, one end of the stirring blade 16 is inserted into the drum body 1 and the feed port 3 for internal stirring during replenishment. Afterward, manually rotate the rotating block 11, causing the rotating rod 5 and its stirring rod 8 and stirring blade 16 to rotate. The rotation of the stirring rod 8 and stirring blade 16 effectively prevents toner clumping and blockage, ensuring... The good flowability of the toner, coupled with the periodic impact of the striking ball 10 connected to the rope 9 against the inner wall of the toner box 2 under centrifugal force, dislodging the attached toner and reducing the risk of blockage at the discharge port 4. Simultaneously, the torsion spring 7 stores energy when the rotating block 11 is rotated. When the rotating block 11 is released, the torsion spring 7 releases the energy, causing the rotating rod 5 and its associated stirring rod 8 and stirring blade 16 to rotate in the opposite direction, further enhancing the turbulence and anti-blocking effect. After toner replenishment, the pull rod 14 is pulled and fixed to one end of the rotating rod 5 via the bolt rod 15, ensuring a stable position. This action causes the stirring blade 16 and the square sliding rod 12 to move with the pull rod 14. The stirring blade 16 retracts into the toner box 2, while the baffle 17 re-enters the discharge port 4 and comes into close contact with the sealing ring 18, automatically closing the discharge channel of the discharge port 4 to prevent toner leakage. The cooperation between the sealing ring 18 and the baffle 17 ensures a good sealing effect.
