Description

Technical Field

[0001] The present invention relates to the technical field of ink cartridge inking, and in particular to an ink cartridge inking device and an inking method for a printer. Background Art

[0002] The ink cartridge of a printer is used to store ink so that the printer can print. When the ink in the cartridge is used up, it is generally necessary to replace it with a new cartridge. Replacing the cartridge body together will increase the cost of using the printer. Therefore, after the ink in the cartridge is used up, ink can be added to the cartridge to restore the printing function of the printer.

[0003] In the prior art, the ink outlet of most ink cartridges is controlled by a circuit to release ink, and the circuit program is generally integrated on the ink cartridge body. Therefore, the ink cartridge is not only used to store ink, but also needs to control the output of ink. The circuit between the printer body and the ink cartridge is generally connected through contacts. Therefore, when replacing the ink cartridge, the chip contacts on the ink cartridge need to be extra protected. If the chip contacts are contaminated, the ink cartridge may be damaged. Since it is necessary to avoid accidental touching of the chip contacts when filling in ink, the inking work will be slower. In addition, after inking, since there are still bubbles remaining at the ink outlet of the ink cartridge, ink absorption treatment is required after inking to ensure printing quality. In the prior art, a specific ink absorption tool is required, and the amount of ink absorption cannot be effectively controlled. If the amount of ink absorption is large, it will affect the ink storage capacity of the ink cartridge. If the amount of ink absorption is small, the bubbles at the ink outlet of the ink cartridge cannot be effectively discharged. Summary of the invention

[0049] Another aspect of the present invention provides an inking method for an inking device for an ink cartridge of a printer, comprising the following steps:

[0050] Step 1: Ink is injected into the storage box through the ink injection tube. After the ink is injected, the ink injection tube needs to be sealed immediately;

[0051] Step 2: Slide the connection seat, remove the connection seat and the components on the connection seat from the whole device, and then remove the ink cartridge from the printer. The user needs to pull the fixing plate, place the ink outlet at the bottom of the ink cartridge on the first sealing ring, and then loosen the fixing plate. Under the action of the third spring, the ink cartridge is squeezed through the fixing plate, and the ink cartridge is fixed with the door frame. At this time, the chip contacts on the ink cartridge are protected under the action of the rubber ring on the fixing plate to avoid the contacts from being contaminated during subsequent operations. Then the tape on the ink injection hole of the ink cartridge can be torn off;

[0052] Step 3: Insert the connecting seat into the device through the slide groove and the connecting block, and slide between the slide groove and the connecting block to align the ink injection hole on the ink cartridge with the needle;

[0053] Step 4: Turn on the switch of the air cylinder to make the bracket drop as a whole. During the process of the bracket dropping, the needle is driven into the ink injection hole. At the same time, the bracket drops and cooperates with the support provided by the second spring to the connecting seat to achieve secondary clamping of the ink cartridge, and the connecting seat is also dropped, so that the second sealing ring on the support tube contacts the top of the L-shaped tube;

[0054] Step 5: Turn on the switch of the electric telescopic rod. When the electric telescopic rod is working, the cover body is lifted up along the tube body through the support of the first fixing frame and the transmission of the second fixing frame. In this process, the switch of the solenoid valve is turned on, so that the ink in the storage box can enter the tube body through the filter tube and the solenoid valve. When the ink passes through the filter tube, it is filtered by the filter element, so that the deteriorated particles in the ink are blocked. When the cover body moves to a certain position, the switch of the solenoid valve is turned off, and then the cover body is continuously pushed up by the electric telescopic rod, so that the air pressure under the cover body in the tube body is reduced, thereby bursting the bubbles on the surface of the ink to prevent the bubbles from entering the ink cartridge with the ink.

[0055] Step 6: The cover is driven to descend by the electric telescopic rod. In the initial stage of the descent of the cover, the upper gas in the cover enters the second hose through the gap between the cover and the plug, and then enters the transparent tube through the first one-way valve. As the cover descends, the ink contacts the float. Then, under the action of buoyancy, the float drives the plug to rise through the slide rod to seal the top of the cover. After that, the cover continues to descend, so that the ink under the cover enters the tube through the connecting tube and the second one-way valve and is located above the cover.

[0056] Step 7: Control the electric telescopic rod to repeatedly drive the cover body to rise and fall, until the ink is pushed into the connecting tube during the rising process of the cover body, and then the ink is injected into the ink cartridge through the first hose and the needle;

[0057] Step 8: After the inking is completed, the user pulls the plate again, and the rubber tube is deformed to make the plate move away from the box body to reduce the air pressure in the box body. The ink cartridge and the support tube are sealed by the first sealing ring, and the support tube and the L-shaped tube are sealed by the second sealing ring. After the air pressure in the box body is reduced, the ink in the ink cartridge enters the box body through the ink outlet, the support tube, and the L-shaped tube. Due to the flat structure of the box body, it is possible to clearly see whether the sucked ink contains bubbles on the premise of sucking out a small amount of ink. When the ink in the box body does not contain bubbles, stop pulling the plate, and then push and pull the connecting rod to move the push plate in the box body. In this process, the ink in the box body is pushed into the connecting box by the push plate, and the ink is absorbed by the sponge in the connecting box to facilitate the next ink cartridge inking operation;

[0058] Step 9: Reset the bracket by driving the cylinder, pull the connecting seat out of the connecting block, adhere new tape to the ink filling hole of the ink cartridge, and finally remove the ink cartridge from between the fixed plate and the gantry to complete the inking work.

[0059] Compared with the prior art, the beneficial effects of the present invention are:

[0060] (1) The present invention provides a fixing assembly and a connecting seat, so that the ink cartridge can be fixed on the connecting seat through the fixing assembly to avoid contamination of the chip contacts of the ink cartridge during the inking process. At the same time, after the ink cartridge is fixed, the ink cartridge can be quickly fixed on the device through the cooperation between the connecting seat and the connecting block.

[0061] (2) The present invention provides a clamping assembly, a fixing assembly, a connecting block and a connecting seat, so that after the ink cartridge is fixed, the ink outlet of the ink cartridge and the support tube are connected and have good sealing performance through the first sealing ring, and cooperate with the work of the clamping assembly to connect the support tube and the ink suction assembly. Therefore, after inking is completed, the ink in the ink cartridge is drawn out through the ink outlet through the ink suction assembly to discharge the bubbles at the ink outlet, thereby ensuring that the ink cartridge can start printing immediately after inking and reinstalling it back into the printer, and ensuring the printing quality.

DETAILED DESCRIPTION

[0075] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0076] Combine the following Figures 1 to 10 As shown, the present invention provides an ink filling device for a printer cartridge, comprising:

[0077] A base 101, a storage box 201 is disposed on one side of the top of the base 101, and an injection assembly is disposed through the top of the storage box 201;

[0078] A control component, which is arranged in the injection component and is used to control the gas-liquid separation in the injection component;

[0079] Four prisms 102, the four prisms 102 are arranged on the top of the base 101 in a rectangular shape, and a connecting block 103 is slidably arranged on each prism 102;

[0080] A connecting seat 501, wherein both side walls of the connecting seat 501 are provided with a slide groove 506, and the slide groove 506 is adapted to the connecting block 103, and a rectangular hole is provided on the top of the connecting seat 501;

[0081] Support tube 507, support tube 507 is fixed in the rectangular hole, the top of support tube 507 is an open structure, a first sealing ring 508 is fixed to the open end of support tube 507, and a second sealing ring 509 is provided through the bottom of support tube 507;

[0082] A fixing component, which is disposed on the top of the connecting seat 501 and is used to fix the ink cartridge;

[0083] An ink absorbing assembly, which is arranged on the top of the base 101 and is adapted to fit the second sealing ring 509;

[0084] The clamping assembly is arranged on the top of the base 101 , and the clamping assembly is slidably connected to the four prisms 102 . The clamping assembly is used to press the connecting seat 501 downward to connect the ink absorbing assembly and the second sealing ring 509 .

[0085] Through the sliding between the connecting seat 501 and the four connecting blocks 103, the connecting seat 501 and the fixing components on the connecting seat 501 can be quickly installed and removed from the device. The fixing components can be used to quickly fix and remove the ink cartridge from the connecting seat 501, so as to quickly install and fix the ink cartridge to the device.

[0086] During the inking operation, the clamping assembly cooperates with the sliding of the connecting block 103 on the prism 102, so that the clamping assembly can push the connecting seat 501 and the ink cartridge on the connecting seat 501 to descend, so that the ink cartridge and the ink absorbing assembly are connected, and the ink absorbing operation is performed immediately after the inking is completed, so as to ensure the printing effect after the ink cartridge is inked;

[0087] Through the control component in the injection component, it can be achieved that during the inking process, the ink entering the ink cartridge does not contain bubbles, further ensuring the printing quality after inking.

[0088] Further, the injection assembly comprises:

[0089] The tube body 301 is fixed through the top of the storage box 201, and a transparent tube 302 is fixed on the top of the tube body 301;

[0090] The first fixing frame 316 (such as Figure 8 As shown), the first fixing frame 316 is fixed in the tube body 301, and the electric telescopic rod 315 is fixed on the top of the first fixing frame 316;

[0091] The second fixing frame 319 (such as Fig.10 As shown), the second fixing frame 319 is fixed on the telescopic end of the electric telescopic rod 315, a cover body 313 is fixed on the second fixing frame 319, a piston ring 314 is fixedly sleeved on the cover body 313, and the piston ring 314 is in contact with the inner wall of the tube body 301, and the control component is arranged in the cover body 313;

[0092] The connecting pipe 317 penetrates and is fixed on the side wall of the cover body 313 . The bottom end of the connecting pipe 317 is a “U”-shaped structure, and the top end of the connecting pipe 317 is provided with a second one-way valve 318 .

[0093] Furthermore, the injection assembly also includes:

[0094] Solenoid valve 307, the solenoid valve 307 is arranged through the bottom of the tube body 301;

[0095] The filter tube 308 is fixed at the bottom of the solenoid valve 307 , and the filter tube 308 and the solenoid valve 307 are connected, and a filter element 312 is fixed in the filter tube 308 .

[0096] When the solenoid valve 307 is turned on, the electric telescopic rod 315 works to push the cover body 313 up, and cooperate with the piston ring 314 on the cover body 313, so that the ink in the storage box 201 can enter the tube body 301 through the filter tube 308. Under the action of the filter element 312 in the filter tube 308, the solid impurities in the ink are filtered to ensure the quality of the ink entering the ink cartridge.

[0097] Furthermore, the injection assembly also includes:

[0098] A support plate 309, the support plate 309 is fixed on the inner wall of the transparent tube 302;

[0099] A second hose 311, the second hose 311 is passed through and fixed on the top of the cover body 313, and the second hose 311 is fixed to the support plate 309, and a first one-way valve 310 is fixed on the top of the second hose 311;

[0100] A pressure relief valve 303, the pressure relief valve 303 is fixedly disposed through the top of the transparent tube 302;

[0101] A connecting pipe 304, which penetrates and is fixed on the side wall of the tube body 301, and the end of the connecting pipe 304 in the tube body 301 is tilted upward;

[0102] A first hose 305, the first hose 305 is connected to the connecting pipe 304;

[0103] The needle 306 is communicated with the first hose 305 .

[0104] During the process of the cover body 313 rising, after closing the solenoid valve 307, the cover body 313 rises until it rises close to the connecting pipe 304. During this process, the air pressure below the cover body 313 in the tube body 301 decreases. If there are bubbles on the surface of the ink, they will burst under the action of the air pressure, thereby achieving defoaming of the ink.

[0105] After defoaming is completed, the cover body 313 begins to descend. Through the operation of the control component, during the descent of the cover body 313, the air below the cover body 313 first enters the transparent tube 302 through the second hose 311, so as to separate the ink and the gas below the cover body 313. At the same time, since the end of the second hose 311 is in the transparent tube 302 and the gas rises through the second hose 311, the generation of new bubbles is avoided during the separation of the ink and the gas.

[0106] Through the action of the transparent tube 302, the gas content in the transparent tube 302 can be clearly seen. When the gas content in the transparent tube 302 is high and before the liquid level of the ink is about to approach the connecting tube 304, the pressure relief valve 303 needs to be opened. At this time, the cover 313 is driven to rise by the control component to discharge the gas above the transparent tube 302 through the pressure relief valve 303, thereby achieving complete immersion of the connecting tube 304 with the ink, so as to prevent the gas mixed with the ink from being output through the connecting tube 304;

[0107] If the sealing performance of the cover body 313 or the piston ring 314 decreases, the gas in the cover body 313 rises in the ink. The connecting tube 304 with its end tilted upward can prevent the gas from entering the connecting tube 304 during the upward movement in the ink, thereby further ensuring that the ink entering the ink cartridge does not contain bubbles.

[0108] Furthermore, the control component includes:

[0109] A connecting frame 320, the connecting frame 320 is fixed on the inner wall of the cover body 313;

[0110] The slide rod 321 is slidably inserted on the top of the connecting frame 320 , a plug 322 is fixed on the top of the slide rod 321 , and a floating ball 323 is fixed on the bottom of the slide rod 321 .

[0111] After the cover body 313 rises to the highest point, the gas in the cover body 313 is at the top of the cover body 313, and then the cover body 313 descends. In the initial stage of the descent of the cover body 313, the upper gas in the cover body 313 enters the second hose 311 through the gap between the cover body 313 and the plug 322, and then enters the transparent tube 302 through the first one-way valve 310. As the cover body 313 descends, the ink contacts the float 323, and then under the action of buoyancy, the float 323 drives the plug 322 to rise through the slide rod 321 to seal the top of the cover body 313. Thereafter, the cover body 313 continues to descend, so that the ink below the cover body 313 enters the tube body 301 through the connecting tube 317 and the second one-way valve 318 and is located above the cover body 313.

[0112] Furthermore, an ink injection tube 202 is provided through the top of the storage box 201 .

[0113] Furthermore, the fixing assembly includes:

[0114] A gantry frame 502, which is fixed on the top of the connecting seat 501;

[0115] Two rod bodies 505, both of which are slidably disposed on the side wall of the door frame 502;

[0116] A fixing plate 503, the fixing plate 503 and the two rods 505 are fixed, and a rubber ring 504 is fixed to the side wall of the fixing plate 503;

[0117] Two third springs 510 , both of which are fixed on the inner wall of the portal frame 502 , and the two third springs 510 are fixed to the two rods 505 respectively.

[0118] Further, the clamping assembly comprises:

[0119] Two cylinders 401, both of which are fixed on the top of the base 101, and the telescopic ends of the two cylinders 401 are fixed with connecting plates 402;

[0120] The bracket 106 is slidably connected to the four prisms 102, and the two connecting plates 402 are fixed to the bracket 106, and the needle 306 is fixed to the top of the bracket 106;

[0121] Four first springs 104, the four first springs 104 are respectively fixed to the four connecting blocks 103, and the four first springs 104 are all fixed to the bracket 106;

[0122] Four second springs 105 , the four second springs 105 are respectively fixed to the four connecting blocks 103 , and the four second springs 105 are all fixed to the base 101 .

[0123] The second spring 105 supports the connecting block 103, so that the connecting seat 501 and the connecting block 103 can be initially fixed on the device after being connected. When the cylinder 401 is working, the bracket 106 is driven to descend. During this process, the needle 306 on the bracket 106 enters the ink injection hole of the ink cartridge. At the same time, the bracket 106 squeezes the ink cartridge, causing the connecting seat 501 to descend, and also causing the second sealing ring 509 to conflict with the ink absorption component, thereby achieving communication between the support tube 507 and the ink absorption component. At the same time, the second sealing ring 509 ensures the sealing between the support tube 507 and the ink absorption component.

[0124] Further, the ink absorbing component comprises:

[0125] An L-shaped tube 601, the L-shaped tube 601 is fixed to the top of the base 101, and the top of the L-shaped tube 601 is adapted to the second sealing ring 509;

[0127] A rubber tube 604, the rubber tube 604 is fixed to the open end of the box body 602, and a plate body 605 is fixed to the end of the rubber tube 604;

[0128] A push plate 606 is slidably disposed in the box body 602, a connecting rod 607 is fixed to the side wall of the push plate 606, and the connecting rod 607 passes through the side wall of the box body 602;

[0129] The connection box 603 is fixed to the box body 602 , and the connection box 603 and the box body 602 are communicated with each other, and a sponge is fixed inside the connection box 603 .

[0130] After inking, the plate 605 is pulled, and the rubber tube 604 is deformed to make the plate 605 move away from the box body 602 to reduce the air pressure in the box body 602. The ink in the ink cartridge enters the box body 602 through the ink outlet, the support tube 507, and the L-shaped tube 601. Due to the flat structure of the box body 602, it is possible to clearly see whether the sucked ink contains bubbles after sucking out a small amount of ink. As the ink suction proceeds, the gas at the ink outlet of the ink cartridge is completely extracted, and the ink entering the box body 602 thereafter does not contain bubbles. At this time, the ink suction can be stopped, ensuring a better printing effect when the ink cartridge is reinstalled into the printer.

[0131] Another aspect of the present invention provides an inking method for an inking device for an ink cartridge of a printer, comprising the following steps:

[0132] Step 1: Ink is injected into the storage box 201 through the ink injection tube 202. After the ink is injected, the ink injection tube 202 needs to be sealed immediately;

[0133] Step 2: Slide the connecting seat 501, remove the connecting seat 501 and the components on the connecting seat 501 from the whole device, and then remove the ink cartridge from the printer. The user needs to pull the fixing plate 503, place the ink outlet at the bottom of the ink cartridge on the first sealing ring 508, and then loosen the fixing plate 503. Under the action of the third spring 510, the ink cartridge is squeezed through the fixing plate 503, and the door frame 502 is cooperated to fix the ink cartridge. At this time, under the action of the rubber ring 504 on the fixing plate 503, the chip contacts on the ink cartridge are protected to prevent the contacts from being contaminated during subsequent operations. Then the tape on the ink injection hole of the ink cartridge can be torn off;

[0134] Step 3: Insert the connection base 501 into the device through the slide groove 506 and the connection block 103, and slide between the slide groove 506 and the connection block 103 to align the ink injection hole above the ink cartridge with the needle 306;

[0135] Step 4: Turn on the switch of the cylinder 401, so that the bracket 106 is lowered as a whole. During the lowering process of the bracket 106, the needle 306 is driven to enter the ink injection hole. At the same time, the bracket 106 is lowered to cooperate with the support provided by the second spring 105 to the connecting seat 501 to achieve secondary clamping of the ink cartridge, and the connecting seat 501 is also lowered, so that the second sealing ring 509 on the support tube 507 and the top of the L-shaped tube 601 are in conflict;

[0136] Step 5: Turn on the switch of the electric telescopic rod 315. When the electric telescopic rod 315 is working, the cover body 313 is lifted up along the tube body 301 through the support of the first fixing frame 316 and the transmission of the second fixing frame 319. In this process, the switch of the solenoid valve 307 is turned on, so that the ink in the storage box 201 can enter the tube body 301 through the filter tube 308 and the solenoid valve 307. When the ink passes through the filter tube 308, it is filtered by the filter element 312, so that the deteriorated particles in the ink are blocked. When the cover body 313 moves to a certain position, the switch of the solenoid valve 307 is turned off, and then the cover body 313 is continuously pushed up by the electric telescopic rod 315, so that the air pressure under the cover body 313 in the tube body 301 is reduced, thereby causing the bubbles on the surface of the ink to burst, so as to prevent the bubbles from entering the ink cartridge with the ink.

[0137] Step 6: The cover 313 is driven to descend by the electric telescopic rod 315. In the initial stage of the descent of the cover 313, the upper gas in the cover 313 enters the second hose 311 through the gap between the cover 313 and the plug 322, and then enters the transparent tube 302 through the first one-way valve 310. As the cover 313 descends, the ink contacts the float 323. Then, under the action of buoyancy, the float 323 drives the plug 322 to rise through the slide rod 321 to seal the top of the cover 313. Thereafter, the cover 313 continues to descend, so that the ink below the cover 313 enters the tube 301 through the connecting tube 317 and the second one-way valve 318 and is located above the cover 313.

[0138] Step 7: Control the electric telescopic rod 315 to repeatedly drive the cover body 313 to rise and fall, until the ink is pushed into the connecting tube 304 during the rising process of the cover body 313, and then the ink is injected into the ink cartridge through the first hose 305 and the needle 306;

[0139] Step 8: After the inking is completed, the user pulls the plate 605 again, and the rubber tube 604 is deformed to make the plate 605 away from the box body 602, so as to reduce the air pressure in the box body 602. The first sealing ring 508 seals the ink cartridge and the support tube 507, and the second sealing ring 509 seals the support tube 507 and the L-shaped tube 601. After the air pressure in the box body 602 is reduced, the ink in the ink cartridge enters the box body 602 through the ink outlet, the support tube 507, and the L-shaped tube 601. The flat structure of 602 can clearly show whether there are bubbles in the sucked ink after sucking out a small amount of ink. When the ink in the box body 602 does not contain bubbles, the plate body 605 is stopped from being pulled, and then the push plate 606 is moved in the box body 602 by pushing and pulling the connecting rod 607. In this process, the ink in the box body 602 is pushed into the connecting box 603 by the push plate 606, and the ink is absorbed by the sponge in the connecting box 603, so as to facilitate the next ink filling operation of the ink cartridge.

[0140] Step nine: Drive the bracket 106 to reset through the cylinder 401, pull the connecting seat 501 out of the connecting block 103, and then adhere the new tape to the ink injection hole of the ink cartridge. Finally, remove the ink cartridge from between the fixed plate 503 and the gantry 502 to complete the inking work.
