Description

Technical Field

[0001] This invention relates to the field of recycled ink cartridge refurbishment technology, specifically to an automated ink filling device for recycled ink cartridge refurbishment. Background Technology

[0002] Recycled ink cartridges are environmentally friendly printing consumables that restore printing functionality and allow for reuse after recycling, disassembling, testing, repairing and replacing core components, and refilling ink into used original ink cartridges. Ink filling equipment is a type of device used to accurately inject ink into printing consumables or printing equipment such as ink cartridges and ink tanks. Automated ink filling equipment for recycled ink cartridge refurbishment is the core equipment in the recycled ink cartridge production process. Through an automated structure, it achieves accurate ink filling and stable operation, and is adapted to the needs of large-scale refurbishment processing.

[0003] When refilling remanufactured ink cartridges, ink is usually injected through a syringe inserted into the ink filling port. When air is expelled from the ink along with the cartridge through the syringe, ink splashing can easily occur, affecting the ink filling process. Foreign objects in the ink can also easily clog the ink channels or the ink filling syringe during the ink filling process, preventing ink from being injected into the cartridge. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automated ink refilling device for refurbishing recycled ink cartridges, comprising:

[0005] The frame, on the top of which a liquid pump and a conveying mechanism are fixedly installed;

[0006] The ink storage mechanism and the ink injection mechanism are both installed on the top of the frame. The inlet of the liquid pump is connected to the ink storage mechanism through a pipe, and the outlet of the liquid pump is connected to the ink injection mechanism through a pipe.

[0007] The ink filling mechanism includes a sliding frame with an inner slide plate slidably mounted on its inner wall. Cylinders are fixedly mounted on both sides of the sliding frame, with the output end of each cylinder fixedly connected to the bottom of the inner slide plate. A support base is fixedly mounted at the center of the top of the inner slide plate, and an exhaust canister is fixedly mounted on the top of the support base. The exhaust canister, in conjunction with an exhaust pipe, forms a storage space before ink is injected into the ink cartridge, allowing ink to accumulate within it. Air in the ink flows upwards within this accumulation space and is discharged through the gap between the exhaust pipe and the float. Simultaneously, when the ink level is too high, the float's buoyancy within the ink can block the exhaust pipe. This venting process before ink filling prevents ink splashing during injection into the regenerated ink cartridge via a syringe, as the simultaneous discharge of gas and ink causes ink to splatter. An exhaust pipe is fixedly mounted at the center of the top of the exhaust canister, with its bottom end penetrating the canister and extending into its interior. The inner diameter of the exhaust pipe gradually increases from top to bottom. A float is installed inside the exhaust pipe, with a diameter smaller than the maximum inner diameter of the exhaust pipe.

[0008] Preferably, an inlet pipe is fixedly installed on the outer side of the exhaust tank, and the end of the inlet pipe away from the exhaust tank is connected to the outlet of the liquid pump through a pipe. An inner baffle is fixedly installed on the inner wall of the exhaust tank, and there is a gap between the top of the outer side of the inner baffle and the inner wall of the exhaust tank. An outlet pipe is fixedly installed on the bottom of the exhaust tank. A slotted plate is fixedly installed on the outer side of the inner slide plate, and a connecting plate is fixedly installed on the inner wall of the slotted plate. An ink gun is fixedly installed on the inner wall of the connecting plate, and the top end of the ink gun is connected to the bottom end of the outlet pipe through a pipe. The bottom end of the ink gun is provided with... The ink-filling needle has sliding grooves on both sides of the top of the empty slot plate, and a pressure frame is slidably installed at each of the sliding grooves. Before the ink-filling needle of the ink gun is inserted into the ink cartridge, the pressure frame, in conjunction with the rubber plate, applies pressure to the ink cartridge to restrict its movement. Then, during the annular compression process of the elastic pad, the ink-filling needle gradually approaches the ink cartridge until it is inserted into the ink filling port of the ink cartridge. This prevents the ink cartridge from moving when the needle is inserted into the ink cartridge, which could damage the ink cartridge under the insertion pressure or cause the needle to break. An elastic pad ring is fixedly installed between the pressure frame and the empty slot plate.

[0009] Preferably, the ink storage mechanism includes an ink storage box, with an ink outlet pipe fixedly installed at the bottom of the outer side of the ink storage box. The end of the ink outlet pipe away from the ink storage box is connected to the inlet of a liquid pump via a pipe. A first motor is fixedly installed at the center of the top of the ink storage box, and the output end of the first motor passes through the ink storage box and extends into its interior. An annular groove cylinder is fixedly installed on the inner wall of the ink storage box, with an annular groove at the bottom of the annular groove cylinder. A through-groove cylinder is rotatably installed at the annular groove of the annular groove cylinder. Through the through-groove cylinder cooperating with a filter screen, the filled ink is filtered during operation. This system cleans foreign objects from the ink, preventing them from flowing into the ink pipes and clogging them, which would affect the ink delivery during automatic ink filling. It also works in conjunction with a slag collection cylinder to create a foreign object storage space below the filter position, preventing filtered foreign objects from accumulating in the filter area and causing blockages. An ink filling tube is fixedly installed on the top of the ink storage box, with its bottom end penetrating the ink storage box and extending into the interior of the annular groove cylinder. The outer side of the groove cylinder is evenly provided with grid grooves, and the inner diameter of the groove cylinder gradually increases from top to bottom. A groove plate is fixedly installed on the top of the inner wall of the groove cylinder.

[0010] Preferably, a connecting shaft is fixedly installed on the top of the through-slot disc, and the top end of the connecting shaft is fixedly connected to the output end of the first motor via a coupling. A filter screen is fixedly installed on the inner wall of the through-slot cylinder, and a slag collection cylinder is rotatably installed on the bottom of the outer side of the filter screen. The bottom of the slag collection cylinder is fixedly connected to the inner wall of the ink storage box. An outer baffle cylinder is fixedly installed on the inner wall of the ink storage box. The outer baffle cylinder is located on the outer side of the through-slot cylinder. Arc-shaped through-slots are evenly opened on the outer side of the outer baffle cylinder, and an inner guide cover is fixedly installed on the inner wall of the outer baffle cylinder. Through the cooperation of the inner guide cover and the outer baffle cylinder, after the ink is filtered, it enters the sedimentation area between the outer baffle cylinder and the through-slot cylinder and stays on the inner side of the outer baffle cylinder, so that the fine sediment particles in the ink accumulate inside the outer baffle cylinder, preventing them from being discharged and preventing the sediment particles from clogging the ink injection needle tube. The top end of the inner guide cover is higher than the arc-shaped through-slot, and the bottom end of the inner guide cover is lower than the arc-shaped through-slot. The bottom end of the inner guide cover is inclined to the side away from the outer baffle cylinder.

[0011] Preferably, the conveying mechanism includes a conveying trough, with a second motor fixedly installed at both ends of the outer side of the conveying trough, a positioning component fixedly installed at the center of the top of the conveying trough, guide rollers rotatably installed at both ends of the inner wall of the conveying trough, one end of the guide rollers being fixedly connected to the output end of the second motor, a conveyor belt being driven between the guide rollers, side guide posts rotatably installed on both sides of the inner wall of the conveying trough, the side guide posts being evenly installed on the inner wall of the conveying trough, and a bottom support plate fixedly installed at the center of the inner wall of the conveying trough, the top of the bottom support plate being in contact with the inner wall of the conveyor belt.

[0012] Preferably, the positioning component includes a side groove plate, the non-opposing surfaces of which are fixedly connected to the inner wall of the conveying trough, and a sliding groove is formed at the bottom of the opposing surfaces of the side groove plate. Side sliding plates are slidably installed at the sliding grooves of the side groove plate. An inner gasket ring, made of elastic material, is fixedly installed between the bottom of the side sliding plates and the side groove plate. A pressure plate is fixedly installed between the side sliding plates, and a sloping groove is formed at the top of the pressure plate. The pressure plate is located directly above the bottom support plate. A positioning plate is fixedly installed on one side of the bottom of the pressure plate. The positioning plate, in conjunction with a rubber plate, ensures that the ink cartridge reaches the top of the bottom support plate. Then, the pressure applied by the downward movement of the ink injection mechanism causes the side slide plate to compress the inner annular pad, causing the inclined surface of the positioning plate to gradually contact the side of the ink cartridge. During the downward movement, the position of the ink cartridge is finely adjusted so that the ink injection port of the ink cartridge corresponds to the needle tube. Subsequently, the rubber plate contacts the ink cartridge and cooperates with the ink injection mechanism to restrict the movement of the ink cartridge and prevent the ink injection port of the ink cartridge from deviating from the ink injection needle tube, which would result in the inability to inject ink. The bottom of the pressure plate is fixedly installed with a rubber plate, which is symmetrically installed along the center position of the axis of the pressure plate. The side of the positioning plate near the rubber plate is inclined, and the bottom of the positioning plate is lower than the bottom of the rubber plate.

[0013] This invention provides an automated ink refilling device for refurbishing recycled ink cartridges. It has the following beneficial effects:

[0014] (i) The automated ink filling equipment for refurbishing regenerated ink cartridges, through the cooperation of an exhaust can and an exhaust pipe, forms a storage space before the ink is injected into the ink cartridge, allowing the ink to accumulate in the exhaust can. The air in the ink flows upward in the accumulation space and is discharged through the gap between the exhaust pipe and the float. At the same time, when the ink accumulation level is too high, the buoyancy of the float in the ink can block the exhaust pipe. There is an exhaust process before ink filling, which prevents ink splashing caused by the simultaneous discharge of gas and ink when filling the regenerated ink cartridge through the syringe.

[0015] (ii) The automated ink filling equipment for refurbishing recycled ink cartridges uses a pressure frame that works with a rubber plate before the ink filling needle of the ink gun is inserted into the ink filling position of the ink cartridge to apply pressure to the ink cartridge and restrict its movement. Then, during the annular compression process of the elastic pad, the ink filling needle gradually approaches the ink cartridge until it is inserted into the ink filling port of the ink cartridge, preventing the ink cartridge from moving when the needle is inserted into the ink cartridge, which could damage the ink cartridge under the insertion pressure or cause the needle to break.

[0016] (III) The automated ink filling equipment for refurbishing recycled ink cartridges uses a through-channel cylinder and a filter screen to filter the ink during operation, remove foreign objects from the ink, and prevent foreign objects from clogging the ink pipes when the ink flows in, thus affecting the ink delivery during the automatic ink filling process. At the same time, it works with a slag collection cylinder to form a foreign object storage space below the filtration position, preventing the filtered foreign objects from accumulating in the filtration area and causing blockage.

[0017] (iv) The automated ink filling equipment for refurbishing recycled ink cartridges uses an inner guide cover and an outer baffle to allow the ink to enter the sedimentation zone between the outer baffle and the through-channel cylinder after filtration. The ink stays inside the outer baffle, causing fine sediment particles in the ink to accumulate inside the outer baffle, preventing them from being discharged and preventing sediment particles from clogging the ink filling needle.

[0018] (v) The automated ink filling equipment for refurbishing recycled ink cartridges uses a positioning plate and a rubber plate to work together. After the ink cartridge reaches the top of the bottom support plate, the pressure applied by the downward movement of the ink filling mechanism causes the side slide plate to compress the inner ring of the pad, so that the inclined surface of the positioning plate gradually contacts the side of the ink cartridge. During the downward movement, the position of the ink cartridge is finely adjusted so that the ink filling port of the ink cartridge corresponds to the needle tube. Then the rubber plate contacts the ink cartridge and works with the ink filling mechanism to restrict the movement of the ink cartridge and prevent the ink filling port of the ink cartridge from deviating from the ink filling needle tube, which would result in the inability to fill ink.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] For the first embodiment, please refer to... Figures 1 to 5 The present invention provides a technical solution:

[0034] An automated ink refilling device for refurbishing recycled ink cartridges includes:

[0035] The frame 1 has a liquid pump 5 and a conveying mechanism 4 fixedly installed on its top.

[0036] The ink storage mechanism 2 and the ink injection mechanism 3 are both installed on the top of the frame 1. The inlet of the liquid pump 5 is connected to the ink storage mechanism 2 through a pipe, and the outlet of the liquid pump 5 is connected to the ink injection mechanism 3 through a pipe.

[0037] The ink injection mechanism 3 includes a slide frame 301, an inner slide plate 303 slidably mounted on the inner wall of the slide frame 301, cylinders 302 fixedly mounted on both sides of the slide frame 301, the output end of the cylinders 302 fixedly connected to the bottom of the inner slide plate 303, a support base 310 fixedly mounted at the center of the top of the inner slide plate 303, an exhaust canister 304 fixedly mounted on the top of the support base 310, an exhaust pipe 312 fixedly mounted at the center of the top of the exhaust canister 304, the bottom end of the exhaust pipe 312 penetrating the exhaust canister 304 and extending into its interior, ink is introduced into the exhaust canister 304 through the inlet pipe 311 via a liquid pump 5. During the introduction, the inner baffle 314 cooperates with the inlet pipe 311 to restrict the ink entering the exhaust canister 304, allowing it to pass through the inner baffle 311. The ink overflows through the gap between the top of the 14 and the exhaust can 304 to the inside of the inner baffle 314. After the ink enters the exhaust can 304, it first accumulates inside the exhaust can 304. At the same time, the ink flows upward with the gas inside and enters the exhaust pipe 312. At the same time, the air pressure lifts the float 313. The gap between the float 313 and the bottom of the inner wall of the exhaust pipe 312 is used to guide the exhaust pipe 312 out. When the ink enters the exhaust pipe 312, the float 313 floats continuously as the liquid level rises due to the buoyancy of the ink in the ink. In conjunction with the change in the inner diameter of the exhaust pipe 312, the exhaust pipe 312 is blocked, restricting the ink flow. The inner diameter of the exhaust pipe 312 gradually increases from top to bottom. The float 313 is installed inside the exhaust pipe 312. The diameter of the float 313 is smaller than the maximum value of the inner diameter of the exhaust pipe 312.

[0038] An inlet pipe 311 is fixedly installed on the outside of the exhaust tank 304. The end of the inlet pipe 311 away from the exhaust tank 304 is connected to the outlet of the liquid pump 5 through a pipe. An inner baffle 314 is fixedly installed on the inner wall of the exhaust tank 304. There is a gap between the top of the outer side of the inner baffle 314 and the inner wall of the exhaust tank 304. An outlet pipe 315 is fixedly installed on the bottom of the exhaust tank 304. An empty slot plate 307 is fixedly installed on the outside of the inner slide plate 303. A connecting plate 309 is fixedly installed on the inner wall of the empty slot plate 307. An ink gun 308 is fixedly installed on the inner wall of the connecting plate 309. During ink filling, ink is introduced into the ink gun 308 through the outlet pipe 315. When the regenerated ink cartridge reaches the ink filling position, it is driven by the cylinder 302. The inner slide plate 303 moves downward, causing the pressure frame 305 to first contact the conveying mechanism 4. It works with the conveying mechanism 4 to position the regenerated ink cartridge. As it continues to move downward, the pressure gradually increases, causing the elastic pad ring 306 to deform. The pressure frame 305 gradually moves upward, allowing the ink injection needle at the bottom of the ink gun 308 to be inserted into the ink injection position of the regenerated ink cartridge for ink filling. The top of the ink gun 308 is connected to the bottom of the outlet pipe 315 through a pipe. The bottom of the ink gun 308 is equipped with an ink injection needle. Slide grooves are provided on both sides of the top of the empty slot plate 307, and the pressure frame 305 is slidably installed in the slide grooves of the empty slot plate 307. An elastic pad ring 306 is fixedly installed between the pressure frame 305 and the empty slot plate 307.

[0039] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 8 As shown, the ink storage mechanism 2 includes an ink storage tank 201. An ink outlet pipe 204 is fixedly installed on the bottom of the outer side of the ink storage tank 201. The end of the ink outlet pipe 204 away from the ink storage tank 201 is connected to the inlet of the liquid pump 5 through a pipe. A first motor 202 is fixedly installed at the center of the top of the ink storage tank 201. The output end of the first motor 202 passes through the ink storage tank 201 and extends into its interior. An annular groove cylinder 206 is fixedly installed on the inner wall of the ink storage tank 201. An annular groove is opened at the bottom of the annular groove cylinder 206, and a through groove cylinder 210 is rotatably installed at the annular groove of the annular groove cylinder 206. An ink injection pipe 203 is fixedly installed on the top of the ink storage tank 201. The required amount of ink is injected through the ink injection pipe 203. Ink is introduced into the ink storage tank 201. The newly introduced ink is introduced into the interior of the annular groove cylinder 206 through the ink injection tube 203. At the same time, during operation, the first motor 202 is started, which drives the groove cylinder 210 to rotate through the connecting shaft 209 and the groove plate 208. The newly introduced ink is filtered out by the filter screen 212 inside the groove cylinder 210. The bottom end of the ink injection tube 203 passes through the ink storage tank 201 and extends into the interior of the annular groove cylinder 206. The outer side of the groove cylinder 210 is evenly provided with grid grooves, and the inner diameter of the groove cylinder 210 gradually increases from top to bottom. The groove plate 208 is fixedly installed on the top of the inner wall of the groove cylinder 210.

[0040] A connecting shaft 209 is fixedly installed on the top of the slotted disc 208. The top end of the connecting shaft 209 is fixedly connected to the output end of the first motor 202 via a coupling. A filter screen 212 is fixedly installed on the inner wall of the slotted cylinder 210. A slag collection cylinder 211 is rotatably installed on the bottom of the outer side of the filter screen 212. The bottom of the slag collection cylinder 211 is fixedly connected to the inner wall of the ink storage box 201. After the filter screen 212 filters out foreign objects, the rotation of the slotted cylinder 210 creates a relative force between the foreign objects and the internal ink, causing the foreign objects to detach from the filter screen 212 and accumulate inside the slag collection cylinder 211. At the same time, the ink that has filtered out the foreign objects passes through the slotted cylinder 210 and enters the interior of the outer baffle cylinder 205, passing through the inner guide cover 20. 7. The ink is blocked at the arc-shaped groove position, causing it to settle and precipitate between the outer baffle 205 and the groove cylinder 210. Then, it is discharged through the arc-shaped groove through the gap between the inner guide cover 207 and the outer baffle 205, and introduced into the pipeline ink storage tank 201 under the drive of the liquid pump 5 via the ink outlet pipe 204. The outer baffle 205 is fixedly installed on the inner wall of the ink storage tank 201. The outer baffle 205 is located outside the groove cylinder 210. Arc-shaped grooves are evenly opened on the outer side of the outer baffle 205. The inner guide cover 207 is fixedly installed on the inner wall of the outer baffle 205. The top of the inner guide cover 207 is higher than the arc-shaped groove, and the bottom of the inner guide cover 207 is lower than the arc-shaped groove. The bottom of the inner guide cover 207 is inclined to the side away from the outer baffle 205.

[0041] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 9 to 12 As shown, the conveying mechanism 4 includes a conveying trough 41. A second motor 44 is fixedly installed at both ends of the outer side of the conveying trough 41. A positioning component 45 is fixedly installed at the center of the top of the conveying trough 41. Guide rollers 47 are rotatably installed at both ends of the inner wall of the conveying trough 41. One end of the guide roller 47 is fixedly connected to the output end of the second motor 44. The worker places the regenerated ink cartridge to be filled into the top of the conveyor belt 43. The second motor 44 drives the guide roller 47 to rotate, causing the conveyor belt 43 to gradually move the ink cartridge into the ink filling chamber at the top of the bottom support plate 46. After reaching the ink filling position, the positioning component 45 cooperates with the ink filling mechanism 3 to position the ink cartridge and fill it with ink. After filling, the second motor 44 drives the ink cartridge to move again and exit from the other side. A conveyor belt 43 is installed between the guide rollers 47. Side guide posts 42 are rotatably installed on both sides of the inner wall of the conveying trough 41. The side guide posts 42 are evenly installed on the inner wall of the conveying trough 41. A bottom support plate 46 is fixedly installed at the center of the inner wall of the conveying trough 41. The top of the bottom support plate 46 is in contact with the inner wall of the conveyor belt 43.

[0042] The positioning component 45 includes a side groove plate 451. The non-opposing surfaces of the side groove plate 451 are fixedly connected to the inner wall of the conveying groove 41, and the bottom of the opposing surfaces of the side groove plate 451 is provided with a sliding groove. Side slide plates 453 are slidably installed in the sliding grooves of the side groove plate 451. An inner gasket ring 452 is fixedly installed between the bottom of the side slide plate 453 and the side groove plate 451. The inner gasket ring 452 is made of elastic material. A pressure plate 454 is fixedly installed between the side slide plates 453. When the ink cartridge arrives, the ink filling mechanism 3 moves down, contacts the top of the side slide plate 453, and presses the side slide plate downward, causing the side slide plate 453 to deform the inner gasket ring 452 and move downward. During the movement, through The inclined surface of the positioning plate 456 contacts the side of the ink cartridge to adjust its position. During the adjustment process, the bottom of the rubber plate 455 gradually contacts the ink cartridge and applies pressure to restrict its movement. The top of the pressure plate 454 has an inclined groove, and the pressure plate 454 is located directly above the bottom support plate 46. The positioning plate 456 is fixedly installed on one side of the bottom of the pressure plate 454, and the rubber plate 455 is fixedly installed on the bottom of the pressure plate 454. The rubber plate 455 is symmetrically installed along the center of the axis of the pressure plate 454. The side of the positioning plate 456 near the rubber plate 455 is inclined, and the bottom of the positioning plate 456 is lower than the bottom of the rubber plate 455.

[0043] In use, the ink to be filled is introduced into the ink storage mechanism 2 for storage, and the regenerated ink cartridge to be filled is placed into the conveying mechanism 4. The conveying mechanism 4 drives the regenerated ink cartridge to the ink filling position. Then, the liquid pump 5 is started so that the ink is introduced into the ink filling mechanism 3 through the pipeline from the ink storage mechanism 2. The ink filling mechanism 3 and the conveying mechanism 4 work together to inject the ink into the regenerated ink cartridge.

[0044] In the ink storage mechanism 2, the required ink is introduced into the ink storage box 201 through the ink injection tube 203. The newly introduced ink is then introduced into the annular groove cylinder 206 via the ink injection tube 203. Simultaneously, during operation, the first motor 202 is started, causing the first motor 202 to drive the groove cylinder 210 to rotate via the connecting shaft 209 and the groove plate 208. The newly introduced ink passes through the filter screen 212 inside the groove cylinder 210, which filters out foreign matter. After the filter screen 212 removes the foreign matter, the ink is then discharged through the groove cylinder... The rotation of 210 creates a relative force between the foreign object and the internal ink, causing the foreign object to detach from the filter screen 212 and accumulate inside the slag collection cylinder 211. At the same time, the ink that has filtered out the foreign object passes through the through-groove cylinder 210 and enters the interior of the outer baffle cylinder 205. The inner guide cover 207 blocks the ink at the arc through-groove position, causing the ink to settle between the outer baffle cylinder 205 and the through-groove cylinder 210. Subsequently, the ink is discharged through the gap between the inner guide cover 207 and the outer baffle cylinder 205, through the arc through-groove, and introduced into the pipeline through the ink outlet pipe 204 driven by the liquid pump 5.

[0045] In the ink filling mechanism 3, the liquid pump 5 pumps ink through the inlet pipe 311 into the exhaust tank 304. During the inlet process, the inner baffle 314 cooperates with the inlet pipe 311 to restrict the ink in the exhaust tank 304, causing it to overflow through the gap between the top of the inner baffle 314 and the exhaust tank 304 to the inside of the inner baffle 314. After the ink enters the exhaust tank 304, it first accumulates inside the exhaust tank 304. At the same time, the ink flows upward with the gas inside and enters the exhaust pipe 312. Simultaneously, the air pressure lifts the float 313, and the exhaust pipe 312 is vented through the gap between the float 313 and the bottom of the inner wall of the exhaust pipe 312. After the ink enters the exhaust pipe 312... Utilizing the buoyancy of the float ball 313 in the ink, it continues to float upwards as the liquid level rises. In conjunction with the change in the inner diameter of the exhaust pipe 312, the exhaust pipe 312 is blocked, restricting the ink flow. During ink filling, the ink is introduced into the ink filling gun 308 through the outlet pipe 315. When the regenerated ink cartridge reaches the ink filling position, the cylinder 302 drives the inner slide plate 303 to move downwards, so that the pressure frame 305 first contacts the conveying mechanism 4. In cooperation with the conveying mechanism 4, the position of the regenerated ink cartridge is positioned. Subsequently, during the continuous downward movement, the pressure gradually increases, causing the elastic pad ring 306 to deform. The pressure frame 305 gradually moves upwards, so that the ink filling needle at the bottom of the ink filling gun 308 is inserted into the ink filling position of the regenerated ink cartridge to fill it with ink.

[0046] In the conveying mechanism 4, the worker places the regenerated ink cartridge to be filled into the top of the conveyor belt 43. The second motor 44 drives the guide roller 47 to rotate, so that the conveyor belt 43 carries the ink cartridge gradually into the ink filling position at the top of the bottom support plate 46. After reaching the ink filling position, the positioning component 45 cooperates with the ink filling mechanism 3 to position the ink cartridge and fill it with ink. After filling is completed, the second motor 44 drives the ink cartridge to move again and exit from the other side.

[0047] In the positioning assembly 45, when the ink cartridge arrives, the ink filling mechanism 3 moves down and contacts the top of the side slide plate 453, pressing down on the side slide plate, causing the side slide plate 453 to deform the inner pad ring 452 and move downward. During the movement, the position of the ink cartridge is adjusted by the contact between the inclined surface of the positioning plate 456 and the side of the ink cartridge. At the same time, during the adjustment, the bottom of the rubber plate 455 gradually contacts the ink cartridge and applies pressure to the ink cartridge, restricting the movement of the ink cartridge.
