Description

Technical Field

[0001] This invention relates to the field of toner filling technology, and in particular to a toner filling machine for copier ink cartridges. Background Technology

[0002] A photocopier is an office device that uses optical, electrostatic, or digital technology to quickly copy the contents of original paper documents, pictures, and other materials onto new paper. Its basic working principle is to first scan the original document to create an image, then transfer the image information to the target paper using media such as toner or carbon powder, and finally output a copy that is identical to the original. After the toner in the photocopier is produced, it needs to be filled into the ink cartridge. When filling the ink cartridge, the ink cartridge is placed on the pressure sensor on the support platform of the toner filling machine, with the toner outlet tube located at the opening of the ink cartridge. When the toner filling machine is started, the toner will flow into the ink cartridge.

[0003] However, due to the extremely small diameter of toner particles, during the process of refilling large quantities of ink cartridges, toner falls from the toner outlet of the refiller onto the bottom of the cartridge, easily causing the fine toner to be stirred up and dispersed into the air from the cartridge opening, polluting the working environment. Existing technologies usually install dust suction pipes around the refiller for this purpose, but in actual use, it has been found that the dispersed toner near the toner outlet is difficult to effectively absorb. Placing the dust suction pipes close to the toner outlet also affects the accurate weighing of toner. Prolonged exposure to such a harsh working environment can pose potential health hazards to personnel. Therefore, this application provides a toner refiller for copier cartridges to solve the above problems. Summary of the Invention

[0004] This invention provides a toner filling machine for copier ink cartridges to solve the problem of toner floating in the air, which poses a potential health hazard to on-site operators.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A toner cartridge refiller for copiers includes a refiller body and a toner outlet pipe installed at the toner outlet of the refiller body, and further includes:

[0007] The protective assembly includes a movable tube that is movably inserted into the bottom of the powder outlet tube. A guide cover is fitted on the surface of the movable tube. The guide cover is funnel-shaped. An inner shell is fitted on the outside of the guide cover. An outer shell is fitted on the outside of the inner shell. Several through holes are opened on the inner wall of the inner shell. A frame is fixed on the inner wall of the inner shell corresponding to one of the through holes. The frame is a magnetic frame. Several through holes are opened on the outer wall of the guide cover corresponding to one of the through holes. A frame is fixed on the outer wall of the guide cover corresponding to the two through holes. A sealing plate is rotatably connected to the top of the frame. A receiving cavity is formed between the outer shell and the inner shell. The opposing sides of the frame and the frame are both flat. A suction machine is fixed to the powder filling machine body. The suction machine is connected to the receiving cavity through a pipe.

[0008] During operation, the outer shell is moved downwards, the sealing plate opens, the suction machine starts, and the dispersed toner enters the collection chamber through the through hole. After the toner filling is completed, the outer shell is moved upwards, and the sealing plate closes.

[0009] Preferably, the outer shell and the inner shell, as well as the inner shell and the movable tube, are fixedly connected by a number of connecting rods.

[0010] Preferably, a top ring is fitted on the surface of the movable tube, the top ring is fixed to the top of the outer shell, the inner shell and the guide cover, the bottom of the outer shell and the inner shell are threadedly connected to a bottom ring, a guide sleeve is fixed to the top of the top ring, and an L-shaped guide rod is fixed to the surface of the powder outlet tube, the L-shaped guide rod is movably inserted into the guide sleeve.

[0011] Preferably, the outer shell is composed of a vertical part one and an inclined part one, the inner shell is composed of a vertical part two and an inclined part two, the bottom ring is threadedly connected to the bottom of the inclined part one and the inclined part two, and the through hole one is opened on the inner wall of the vertical part two.

[0012] Preferably, a filter element is installed between the outer shell and the inner shell, with the lowest point of the filter element being higher than the highest point of the through hole, and the inner side of the filter element being lower than the outer side.

[0013] Preferably, a pull rope is fixed to the top of the sealing plate, and the pull rope is movably passed through the top ring of the pipe and fixed to the surface of the powder outlet pipe.

[0014] Preferably, a sealing ring is fixed to the inner wall of the inner shell, and there is a gap between the bottom of the sealing ring and the top of the ink cartridge.

[0015] Preferably, the top of the sealing ring is provided with a slope, which is used to guide the toner into the ink cartridge.

[0016] Preferably, an L-shaped connecting rod is fixed to the surface of the powder outlet pipe, and a mounting base is fixed to the bottom of the L-shaped connecting rod. The bottom of the mounting base is in the same plane as the bottom of the powder outlet pipe. A contact sensor is fixed inside the mounting base, and several vibrators are fixed to the top of the top ring. The contact sensor is electrically connected to the vibrator. After the powder filling is completed, the outer shell moves upward, the sealing plate adheres to the surface of the frame, and the contact sensor contacts the top ring. At this time, the contact sensor triggers the vibrator to start.

[0017] Preferably, a magnetic ring is fixed inside the mounting base. After the powder filling is completed, the outer shell moves upward and the magnetic ring is magnetically attracted to the surface of the top ring.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above solution, by setting up protective components and a suction machine, during operation, the outer shell is moved downwards and covers the top of the ink cartridge. The sealing plate is then attached to the second through hole. The suction machine is activated, creating negative pressure at the first through hole. The scattered toner is guided by the guide cover, allowing it to smoothly enter the collection chamber from the first through hole, preventing toner from scattering in the air and protecting the health of the operators. After filling, the outer shell is moved upwards, and the sealing plate is attached to the first through hole, preventing toner from escaping from that hole. The toner is then collected in the collection chamber, achieving toner collection and preventing toner waste.

[0020] By setting up frame one and frame two, both of which have flat sides, the sealing plate can form a tighter seal when it is attached to frame one or frame two. Frame one is made of magnetic material. When the sealing plate is attached to the sealing ring of frame one, the magnetic adsorption effect can stably seal the position of frame one.

[0021] By setting up tilt section one and tilt section two, the space of the storage cavity is increased, allowing the storage cavity to hold more toner.

[0022] By incorporating a filter element, toner in the air can be effectively filtered out, thus preventing toner from entering the suction machine. The filter element has a lower inner side and a higher outer side, causing toner to accumulate on the outer side of the filter element. This effectively prevents toner from completely covering the filter element surface, which would reduce filtration performance and extend the life of the filter element. At the same time, because the toner accumulates on the outer side of the filter element, when toner falls downwards, it can also prevent it from falling into the through hole, thus preventing toner from falling out of the through hole during the next use.

[0023] By setting up a vibrator and a contact sensor, after the toner filling is completed, the outer shell moves upward and the top ring contacts the contact sensor. After the contact sensor is triggered, the vibrator will start. The vibrator can shake the toner off the filter element and collect the toner at the bottom of the collection chamber, thus ensuring the filtration performance of the filter element.

[0034] The following is a detailed description of a toner filling machine for copier ink cartridges provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0035] like Figures 1-8 As shown, an embodiment of the present invention provides a toner refiller for copier ink cartridges, including a toner refiller body 1 and a toner outlet pipe 2 installed at the toner outlet of the toner refiller body 1. A support platform is provided on the toner refiller body 1 and below the toner outlet pipe 2. A pressure sensor is installed on the top of the support platform. The pressure sensor is used to detect whether the amount of toner in the ink cartridge is up to standard. A limit ring is also fixed around the pressure sensor to position the ink cartridge so that the ink cartridge is in the same position each time it is placed. The invention also includes:

[0036] The protective component 4 includes a movable tube 21 that is movably inserted into the bottom of the powder outlet tube 2. A guide cover 13 is fitted on the surface of the movable tube 21. The guide cover 13 is funnel-shaped. An inner shell 8 is fitted on the outside of the guide cover 13. An outer shell 5 is fitted on the outside of the inner shell 8. Several through holes 11 are opened on the inner wall of the inner shell 8. A frame 12 is fixed on the inner wall of the inner shell 8 corresponding to the through holes 11. The frame 12 is a magnetic frame. A sealing ring is provided around the frame 12. Several through holes 24 are opened on the outer wall of the guide cover 13 corresponding to the through holes 11. A frame 25 is fixed on the outer wall of the guide cover 13 corresponding to the through holes 24. A sealing plate 32 is rotatably connected to the top of the frame 12. A receiving cavity 17 is formed between the outer shell 5 and the inner shell 8. The opposing sides of the frame 12 and the frame 25 are both flat. A suction machine 3 is fixed on the powder filling machine body 1. The suction machine 3 is connected to the upper part of the receiving cavity 17 through a pipe.

[0037] During operation, the outer casing 5 is moved downwards, the sealing plate 32 opens, and the suction machine 3 starts. The toner that floats out of the ink cartridge enters the receiving cavity 17 through the through hole 11. After filling, the outer casing 5 is moved upwards, the sealing plate 32 closes, and the movable tube 21 can move with the protective component 4 to ensure precise docking with the ink cartridge during filling. The funnel-shaped guide cover 13 guides the floating toner along the outer wall of the guide cover 13 towards the through hole 11. Combined with the negative pressure formed by the suction machine 3 in the receiving cavity 17, the floating toner smoothly enters the receiving cavity 17. To prevent toner leakage and contamination of the working environment, the planar design of frame 12 and frame 25 allows the sealing plate 32 to fit more tightly. The magnetic frame 12 can attract the sealing plate 32. During toner filling, the sealing plate 32 can be rotated to fit with frame 215 and open the through hole 11 to collect the scattered toner. After filling, the sealing plate 32 fits back with frame 12 and closes the through hole 11 to prevent toner leakage in the storage cavity 17, thus achieving toner collection and protection. The whole process only requires moving the outer shell 5 up and down, making the operation convenient and quick.

[0038] like Figure 3 As shown in this embodiment, the outer shell 5 and the inner shell 8, as well as the inner shell 8 and the movable tube 21, are fixedly connected by several connecting rods 16. The connecting rods 16 fix the outer shell 5, the inner shell 8 and the movable tube 21 as a whole, ensuring that other components move synchronously when the outer shell 5 is moved, avoiding relative displacement from affecting the accuracy of toner filling and toner collection. At the same time, the connection method of the connecting rods 16 does not block the through hole 11 and the storage cavity 17, ensuring smooth toner flow and enhancing the structural stability of the protective component 4.

[0039] like Figure 3As shown in this embodiment, a top ring 18 is fitted on the surface of the movable tube 21. The top ring 18 is fixed to the top of the outer shell 5, the inner shell 8, and the guide cover 13. The bottom of the outer shell 5 and the inner shell 8 are threadedly connected to a bottom ring 19. A guide sleeve 31 is fixed to the top of the top ring 18. An L-shaped guide rod 30 is fixed to the surface of the toner tube 2. The L-shaped guide rod 30 is movably inserted into the guide sleeve 31. The top ring 18 and the bottom ring 19 further reinforce the connection of the outer shell 5, the inner shell 8, and other components. The threaded connection of the bottom ring 19 facilitates disassembly and cleaning of the toner in the storage cavity 17. The L-shaped guide rod 30 cooperates with the guide sleeve 31 to limit the movement direction of the protective component 4, ensuring that the inner shell 8 is located directly above the ink cartridge, avoiding displacement that could lead to misalignment of the toner filling or toner leakage.

[0040] like Figure 3 As shown, in this embodiment, the outer shell 5 is composed of a vertical part 6 and an inclined part 7, and the inner shell 8 is composed of a vertical part 9 and an inclined part 10. The bottom ring 19 is threaded to the bottom of the inclined part 7 and the inclined part 10. The through hole 11 is opened on the inner wall of the vertical part 9. The inclined part 7 and the inclined part 10 increase the volume of the storage cavity 17, which can accommodate more collected toner and reduce the cleaning frequency. The inclined structure can also guide the collected toner to gather towards the bottom ring 19, which is convenient for the toner to be removed from the bottom ring 19 later and reduces residue. The position of the through hole 11 of the vertical part 9 fits the guide cover 13 to improve the toner collection efficiency.

[0041] like Figure 3 As shown in this embodiment, a filter element 22 is installed between the outer shell 5 and the inner shell 8. The lowest point of the filter element 22 is higher than the highest point of the through hole 11. The inner side of the filter element 22 is lower than the outer side. The filter element 22 can filter the air entering the suction machine 3 and prevent toner from damaging the suction machine 3. The design of the inner side being lower than the outer side causes the toner to gather and fall off along the inclined filter element 22 under the action of suction, avoiding clogging the filter element surface and extending the service life of the filter element. The position of the filter element 22 is higher than the through hole 11 to prevent the collected toner from flowing back into the through hole 11 and to ensure stable toner collection.

[0042] like Figure 3 As shown in this embodiment, a pull rope 20 is fixed to the top of the sealing plate 32. The pull rope 20 passes through the top ring 18 and is fixed to the surface of the powder outlet pipe 2. In the initial state, the sealing plate 32 is adsorbed on the surface of the frame 12. When the outer shell 5 is moved downward, the sealing plate 32 is pulled by the pull rope 20, causing the sealing plate 32 to flip and detach from the frame 12, opening the through hole 11. Subsequently, when the outer shell 5 is moved upward, the pull rope 20 is relaxed, and the sealing plate 32 falls naturally to fit against the frame 12 and close the through hole 11. The up and down movement of the outer shell 5 cooperates with the pull rope 20 to realize the automatic linkage control of the sealing plate 32 without additional operation, thus improving convenience.

[0043] like Figure 3 and Figure 7As shown, in this embodiment, a sealing ring 23 is fixed to the inner wall of the inner shell 8. During the toner filling process, pulling the outer shell 5 causes the inner shell 8 and the sealing ring 23 to move down to directly above the ink cartridge, so that the inner shell 8 covers the ink cartridge opening (e.g., Figure 3 As shown, the sealing ring 23 can prevent toner from drifting out from the gap between the inner shell 8 and the ink cartridge. At the same time, there is a certain gap between the bottom of the sealing ring 23 and the top of the ink cartridge. The gap is set to avoid the protective component 4 from contacting the ink cartridge and affecting the weight of the ink cartridge, so as to ensure the accuracy of the weight of the ink cartridge after filling with toner.

[0044] like Figure 7 As shown in this embodiment, the top of the sealing ring 23 is provided with a slope 24. The slope 24 is used to guide the toner into the ink cartridge. The slope 24 can guide the toner that splashes on the sealing ring 23 into the ink cartridge, avoiding toner accumulation on the sealing ring 23 and causing waste, improving toner utilization, and keeping the sealing ring 23 clean.

[0045] like Figure 4 As shown in this embodiment, an L-shaped connecting rod 26 is fixed to the surface of the toner outlet pipe 2, and a mounting base 27 is fixed to the bottom of the L-shaped connecting rod 26. The bottom of the mounting base 27 is in the same plane as the bottom of the toner outlet pipe 2. A contact sensor 28 is fixed inside the mounting base 27, and several vibrators 25 are fixed to the top of the top ring 18. The contact sensor 28 is electrically connected to the vibrator 25. After the toner filling is completed, the outer shell 5 moves upward, and the sealing plate 32 is attached to the surface of the frame 12. The contact sensor 28 contacts the top ring 18. At this time, the contact sensor 28 triggers the vibrator 25 to start, which can shake off the toner attached to the filter element 22, ensuring the filtration efficiency of the filter element 22. At the same time, the toner falls into the bottom of the collection cavity 17 for easy collection. The position of the mounting base 27 ensures that the contact sensor 28 is triggered to vibrate only after the sealing plate 32 closes the through hole 11, avoiding leakage when the toner is shaken off.

[0046] like Figure 4 As shown in this embodiment, a magnetic ring 29 is fixed inside the mounting base 27. After the powder filling is completed, the outer shell 5 moves upward and the magnetic ring 29 is magnetically attracted to the surface of the top ring 18. The magnetic ring 29 magnetically attracts the top ring 18, which can fix the position of the outer shell 5 and other components after the powder filling is completed, preventing them from accidentally moving downward and causing the sealing plate 32 to fall off the frame 12, and ensuring that the through hole 11 is closed and stable.

[0047] Working principle: First, the ink cartridge is placed on the pressure sensor on the main body 1 of the toner filling machine and positioned by the limit ring. Then, the outer shell 5 is moved downward. The outer shell 5 drives the inner shell 8, the guide cover 13 and the movable tube 21 to move downward synchronously through the connecting rod 16. At this time, the outer shell 5 and the inner shell 8 will cover the opening of the ink cartridge. During this process, under the action of the pull rope 20, the sealing plate 32 flips upward and separates from the frame 12 and fits with the frame 15 at the through hole 14. The suction machine 3 is started. The suction machine 3 creates a negative pressure at the through hole 11, so that the toner that floats out of the ink cartridge opening during the toner filling process will be guided by the guide cover 13 and smoothly enter the collection cavity 17 from the through hole 11, preventing the toner from floating into the air, thereby protecting the health of the operator. The toner filling work proceeds normally, and the toner enters the ink cartridge through the toner outlet tube 2 and the movable tube 21.

[0048] After the toner filling is completed, the outer shell 5 is moved upward. The outer shell 5 drives the related components to move upward. The pulling force of the pull rope 20 on the sealing plate 32 gradually disappears. The sealing plate 32 rotates downward under the action of gravity. The sealing plate 32 is separated from the frame 15 at the through hole 14 and finally adheres to the frame 12 at the through hole 11. Since the frame 12 is made of magnetic material and its opposite side that adheres to the sealing plate 32 is flat, the sealing plate 32 can adhere tightly to the sealing ring of the frame 12 under the magnetic adsorption, thereby sealing the through hole 11 and preventing the toner in the storage cavity 17 from floating out from the through hole 11.

[0049] As the outer casing 5 moves upward, the top ring 18 gradually approaches the mounting base 27. When the sealing plate 32 is stably attached to the surface of the frame 12, the top ring 18 contacts the contact sensor 28 inside the mounting base 27. The contact sensor 28 is triggered, which in turn starts the vibrator 25. The vibrator 25 vibrates, shaking off the toner attached to the filter element 22, so that the toner is collected at the bottom of the collection cavity 17. This not only ensures the filtration performance of the filter element 22, but also improves the toner collection effect.

[0050] Meanwhile, the magnetic ring 29 inside the mounting base 27 will be magnetically attracted to the surface of the top ring 18, causing the solid housing 5 and other components to be suspended on the upper side of the ink cartridge. After the ink cartridge with the toner filling completed is transported away, the toner filling operation is carried out again. The toner stored in the storage cavity 17 can be processed later, avoiding toner waste.

[0051] It should be noted that the suction pressure of the suction machine 3 is adjustable, so that the negative pressure formed at the through hole 11 can ensure the adsorption of scattered toner while controlling the impact on the toner weighing accuracy in the ink cartridge within the error range.

[0052] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
