Description

Technical Field

[0001] This invention relates to the field of water-based ink dispensing technology, specifically to a device that facilitates the dispensing of water-based inks. Background Technology

[0002] Water-based inks, also known as liquid inks or flexographic water-based inks, are printing ink systems that use water as the primary solvent or dispersion medium. They are mainly composed of water-soluble resins, organic pigments, solvents, and related additives, processed through compounding and grinding. The water-soluble resin in water-based inks acts as a binder, ensuring uniform dispersion of pigment particles, giving the ink fluidity, and providing adhesion to the substrate. Pigments impart color to the ink. The solvents are primarily water and a small amount of ethanol, used to dissolve the resin and adjust the ink's fluidity, viscosity, and drying properties. Additives include defoamers, pH stabilizers, and slow-drying agents, which respectively inhibit and eliminate bubbles, regulate and control pH and stabilize viscosity, and inhibit and slow down the drying rate.

[0003] Water-based inks are generally dispensed using either a scraper or by placing the ink in a container with a valve and opening the valve by gravity. Dispensing water-based ink by opening the valve has the following disadvantages: First, as the total amount of ink in the container decreases, the flow rate and velocity of the ink discharged from the valve also decrease, making it difficult for workers to control the amount dispensed. Second, water-based ink is prone to residue at the valve, polluting the surrounding environment and affecting normal ink discharge. Furthermore, storing water-based ink in a container requires cleaning the container when changing to a different color, which is cumbersome and time-consuming. Summary of the Invention

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Please see Figure 1-10 The present invention provides a technical solution: a device for facilitating the feeding of water-based ink, including a fixed base 1, a water-based ink storage tank 2 fixedly installed on the upper side of the fixed base 1, a mounting tank cover 3 installed on the upper side of the water-based ink storage tank 2, a pressure movable disc 4 movably installed on the lower side of the mounting tank cover 3, a folding ink discharge pipe 7 installed on the lower side of the water-based ink storage tank 2, and an ink-receiving inner tank 9 installed inside the water-based ink storage tank 2. The cleaning mechanism 5 includes a dual-head motor 501, a first slide groove 507, a second slider 508, and a hinge rod 509. The dual-head motor 501 is fixedly installed on the upper side of the mounting lid 3. Two sets of first slide grooves 507 are opened on the mounting lid 3. The second slider 508 is movably installed in the first slide groove 507. The lower side of each set of second sliders 508 is hinged to a hinge rod 509. One end of the hinge rod 509 is hinged to the upper side of the pressure movable disc 4. The rotating mechanism 6 includes a fixed side plate 601, a movable insertion rod 602, and an insertion cylinder 604. The fixed side plate 601 is fixedly installed at one end of the bucket cover 3, and the movable insertion rod 602 is fixedly installed on the lower side of the fixed side plate 601. The insertion cylinder 604 is fixedly installed on one side of the water-based ink storage bucket 2, and the movable insertion rod 602 is movably inserted into the insertion cylinder 604. The double sealing mechanism 8 includes a mounting box 801, a first sealing circular plate 802, and a second sealing circular plate 809. The mounting box 801 is fixedly installed at the end of the folded ink exhaust tube 7 and communicates with the folded ink exhaust tube 7. The first sealing circular plate 802 is movably installed inside the mounting box 801, and the second sealing circular plate 809 is movably installed on the lower side of the end of the folded ink exhaust tube 7. This equipment pressurizes the ink in the water-based ink container 2 through a sealed pressing method. The ink is then discharged from the end of the folded ink discharge pipe 7 via a connecting vessel, achieving a quantitative discharge of ink from the water-based ink container 2. This discharge method prevents ink discharge when the pressure disc 4 is stationary, increasing the stability of the equipment. The equipment is equipped with a replaceable ink-receiving inner container 9 and a folded ink discharge pipe 7, allowing for quick replacement of inks of different colors within the water-based ink container 2, increasing the functionality and convenience of the equipment. The equipment also features a double sealing mechanism 8 at the end of the folded ink discharge pipe 7, resulting in less ink residue and reducing the likelihood of condensation and blockage. Furthermore, when the double sealing mechanism 8 is open, the pressure disc 4 does not pressurize the ink in the water-based ink container 2, and ink will not discharge from the folded ink discharge pipe 7, making the end of the folded ink discharge pipe 7 easy to clean and increasing the convenience of equipment cleaning.

[0021] Furthermore, the driving cleaning mechanism 5 also includes mounting side plates 502, transmission gears 503, driving screws 504, a first sliding block 505, a first threaded sleeve 506, a rolling wheel 510, and a first shielding box 525. Two sets of mounting side plates 502 are fixedly mounted on the mounting bucket cover 3. Transmission gears 503 are evenly and rotatably mounted on the outer side of the mounting side plates 502. The output shaft of the dual-head motor 501 is fixedly connected to the central transmission gear 503, and the transmission gears 503 mesh with each other. Two sets of driving screws 504 are rotatably mounted between the mounting side plates 502. The threads on the drive screw 504 are in opposite directions. Both ends of the drive screw 504 are fixedly connected to the outer transmission gear 503. Two sets of first sliding blocks 505 are movably mounted between the mounting side plates 502. A first threaded sleeve 506 is fixedly mounted at the center of each first sliding block 505. The first threaded sleeve 506 is threaded onto the drive screw 504. The two sets of first sliding blocks 505 are respectively fixedly mounted on the second slider 508. A first shielding box 525 is fixedly mounted on the mounting barrel cover 3, and the mounting side plates 502 are fixedly mounted inside the first shielding box 525. A schematic diagram of this structure is shown below. Figure 4 The number of transmission gears 503 installed on the same set of mounting side plates 502 is odd, so the drive screws 504 can rotate in the same direction. However, the threads on the two sets of drive screws 504 are opposite, so the two sets of first sliding blocks 505 can move in opposite directions under the drive of the drive screws 504. This structure makes the rotation speed of the drive screws 504 synchronize with the rotation time, thereby driving the pressure movable disc 4 to descend stably and increasing the stability of the equipment during use. Furthermore, the driving cleaning mechanism 5 also includes a second slide groove 511, a guide rod 512, and a guide hole 513. The first slide groove 507 has second slide grooves 511 on both sides. Rolling wheels 510 are rotatably mounted on both sides of the second slider 508, and the rolling wheels 510 roll within the second slide grooves 511. A guide rod 512 is fixedly installed within the first slide groove 507. Each of the second sliders 508 has a guide hole 513, and the guide rod 512 is movably inserted into the guide hole 513. A schematic diagram of this structure is shown below. Figure 4 and Figure 5 The length of the hinge rod 509 is adapted to the height of the water-based ink storage tank 2, ensuring that the pressure movable disc 4 does not completely contact the bottom surface of the water-based ink storage tank 2 during use. When ink is placed in the inner ink container 9, it is not completely filled, creating a noticeable air layer between the upper layer of ink and the ink scraper 521. When the pressure movable disc 4 is pressed down, the ink can be squeezed by the air, reducing ink contamination of the pressure movable disc 4 and improving the ease of cleaning the equipment. The hinge positions of the two sets of hinge rods 509 and the upper side of the pressure movable disc 4 are symmetrically distributed around its center point, effectively ensuring the stability of the pressure movable disc 4 during descent, while the rolling wheel 510 significantly reduces the resistance when the second slider 508 moves. Furthermore, the driving cleaning mechanism 5 also includes an insertion slot 514, a connecting water pipe 515, a threaded connector 516, an annular water groove 517, a drain hole 518, and a threaded water inlet 519. An insertion slot 514 is provided on one side of the mounting lid 3, and the connecting water pipe 515 is movably inserted into the insertion slot 514. A threaded connector 516 is fixedly installed on the lower side of the connecting water pipe 515. An annular water groove 517 is provided on the pressure movable disc 4, and drain holes 518 are arrayed on the pressure movable disc 4, communicating with the annular water groove 517. A threaded water inlet 519 is fixedly installed on the upper side of the mounting lid 3, communicating with the annular water groove 517. The threaded connector 516 is threadedly fitted onto the threaded water inlet 519. A schematic diagram of this structure is shown below. Figure 3 and Figure 6 The length of the connecting water pipe 515 is adapted to the movement of the pressure moving disc 4. When there is no ink stored in the ink-receiving inner tank 9, cleaning fluid can be injected into the ink-receiving inner tank 9 through the connecting water pipe 515. The inner wall of the ink-receiving inner tank 9 is cleaned by the up and down movement of the pressure moving disc 4, which improves the cleaning efficiency of the equipment. This structure does not affect the normal operation of the pressure moving disc 4. Furthermore, the driving cleaning mechanism 5 also includes a first sealing ring 520, an ink scraper 521, an insertion hole 522, a first screw 523, and a second threaded sleeve 524. The first sealing ring 520 is fixedly installed on the upper edge of the pressure movable disc 4, and its outer side is tightly fitted against the inner wall of the ink-receiving inner tank 9. The ink scraper 521 is sleeved on the lower side of the pressure movable disc 4, and its edge is fitted against the inner wall of the ink-receiving inner tank 9. Two sets of insertion holes 522 are provided on the lower side of the ink scraper 521, and the first screw 523 is movably inserted into each insertion hole 522. Two sets of second threaded sleeves 524 are fixedly installed on the lower side of the pressure movable disc 4, and the first screw 523 is threadedly installed into the second threaded sleeves 524. A schematic diagram of this structure is shown below. Figure 6 Through the sealing effect of the first sealing ring 520, the pressure movable disc 4 can utilize the air layer between the ink in the ink-receiving inner tank 9 and the ink scraper 521 to press down, thereby reducing ink contamination of the pressure movable disc 4. Simultaneously, the ink scraper 521 can scrape the inner wall of the ink-receiving inner tank 9, improving ink utilization efficiency and reducing the cleaning difficulty of the ink-receiving inner tank 9. The drain hole 518 is located between the first sealing ring 520 and the ink scraper 521, allowing the sprayed cleaning fluid to remain in this area. When the pressure movable disc 4 moves up and down, the cleaning fluid can fully contact the inner wall of the ink-receiving inner tank 9, thereby improving the equipment's cleaning efficiency. Furthermore, the rotating mechanism 6 also includes a limiting block 603, a limiting groove 605, a first fixing block 606, a second fixing block 607, a third threaded sleeve 608, a second screw 609, a sealing gasket 610, and a pulling belt 611. The lower end of the movable insert rod 602 is fixedly installed with the limiting block 603. The inserting cylinder 604 has a limiting groove 605, and the limiting block 603 is movably inserted into the limiting groove 605. The first fixing blocks 606 are fixedly installed in an array on the mounting lid 3. Water-based oil A second fixing block 607 is fixedly installed on the upper end of the ink storage container 2.

A sealing gasket 610 is fixedly installed on the upper side of the water-based ink storage container 2. A pull strap 611 is fixedly installed on the first shielding box 525. A schematic diagram of this structure is shown below. Figure 2 The limiting groove 605 is an inverted L-shape, and its height is greater than the sum of the heights of the mounting lid 3 and the pressure movable disc 4, so that the mounting lid 3 and the pressure movable disc 4 can be rotated after being lifted, making it easy to remove the ink-collecting inner barrel 9 and disassemble the ink scraper 521. The first shielding box 525 is not completely airtight, and has ventilation gaps to prevent negative pressure from forming when the pressure movable disc 4 descends; Furthermore, a first flange 10 is fixedly installed on the lower side of the ink-receiving inner tank 9. The groove on the lower side of the water-based ink storage tank 2 is adapted to the size of the first flange 10. A second flange 11 is fixedly installed on one end of the folded ink discharge pipe 7. The first flange 10 and the second flange 11 fit together. A receiving block 12 is fixedly installed on the fixed base 1. The folded ink discharge pipe 7 is placed on the upper side of the receiving block 12. A fixing ring 13 is provided on the upper side of the receiving block 12. A limiting block 14 is fixedly installed on the upper end of the folded ink discharge pipe 7. A limiting side plate 15 is fixedly installed on one side of the water-based ink storage tank 2. Two sets of limiting grooves 16 are opened on the upper side of the limiting side plate 15. The limiting block 14 fits into the limiting groove 16. A transparent observation plate 17 is fixedly installed on the front side of the folded ink discharge pipe 7. A schematic diagram of this structure is shown below. Figure 1 , Figure 7 and Figure 8 The shapes of the receiving block 12 and the limiting side plate 15 are adapted to the contour of the folded ink discharge tube 7. The limiting round block 14 is used to limit the position of the folded ink discharge tube 7 in the vertical direction. After the first flange 10 and the second flange 11 are attached, they are connected and fixed by screws and threaded sleeves. The receiving block 12 has a pre-embedded threaded sleeve. The fixing ring 13 is screwed to the receiving block 12 by screws, thereby achieving the clamping and fixing of the folded ink discharge tube 7. Furthermore, the double sealing mechanism 8 also includes a second sealing ring 803, a second shielding plate 804, a mounting cylinder 805, a torsion spring 807, a connecting crank 806, and a connecting rod 817. The second sealing ring 803 is fixedly installed on the first sealing circular plate 802, and the second sealing ring 803 is in contact with the inner wall of the mounting box 801. The second shielding plates 804 are fixedly installed on both sides of the mounting box 801, and the mounting cylinder 805 is fixedly installed on the second shielding plate 804.

One end of the torsion spring 807 is fixedly installed on the connecting crank 806, and the other end is fixedly installed on the inner wall of the mounting cylinder 805. A first gear 808 is fixedly installed on the connecting crank 806. The center of the first gear 808 is fixedly connected to the rotating shaft of the first sealing disc 802. The first gear 808 is located on the outside of the mounting box 801. A connecting rod 817 is fixedly installed between the two sets of connecting cranks 806. A schematic diagram of this structure is shown below. Figure 9 When the first sealing disc 802 is opened, it rotates counterclockwise. Under normal conditions, the torsion spring 807 seals the mounting box 801 with the first sealing disc 802. Under normal conditions, the connecting rod 817 does not contact the upper side of the mounting box 801, making it easier for the user to rotate the connecting rod 817 and improving the ease of operation of the equipment. Furthermore, the double sealing mechanism 8 also includes a rack 810, T-blocks 811, T-slots 812, and a second gear 813. The shape of the second sealing circular plate 809 is adapted to the shape of the upper and lower sides of the folded ink discharge tube 7. Racks 810 are fixedly installed at both ends of the second sealing circular plate 809, and two sets of T-blocks 811 are fixedly installed at the upper end of the second sealing circular plate 809. Two sets of T-slots 812 are opened on the lower side of the mounting box 801, and the T-blocks 811 are movably inserted into the T-slots 812. The second gear 813 is rotatably installed on both sides of the mounting box 801, and the second gear 813 meshes with the rack 810. A schematic diagram of this structure is shown below. Figure 10 The length of the second sealing circular plate 809 is greater than the diameter of the end of the folded ink exhaust tube 7, ensuring that it can completely cover the ink exhaust tube opening; the length of the rack 810 is greater than the second sealing circular plate 809, so that the end of the folded ink exhaust tube 7 can be completely unobstructed in the open state. Furthermore, the double-enclosure mechanism 8 also includes a third gear 814, a fourth gear 815, and a fifth gear 816. The third gear 814 and the fifth gear 816 are rotatably mounted on both ends of the mounting box 801. The fourth gear 815 is fixedly mounted on the third gear 814. The second gear 813 meshes with the third gear 814, the fourth gear 815 meshes with the fifth gear 816, and the fifth gear 816 meshes with the first gear 808. The second gear 813, the third gear 814, the fourth gear 815, and the fifth gear 816 are all located within the second shielding plate 804. A schematic diagram of this structure is shown below. Figure 10The first gear 808, the second gear 813, and the fourth gear 815 are of equal size, and the fifth gear 816 and the third gear 814 are of equal size, with the diameter of the fourth gear 815 being smaller than that of the third gear 814. These multiple gear sets constitute an acceleration gear set, whose transmission ratio is adapted to the movement of the second sealing disc 809, ensuring that when the first sealing disc 802 closes the mounting box 801, the second sealing disc 809 simultaneously closes the folded ink discharge pipe 7, forming a double-sealing structure.

[0022] Working principle: When using this invention, first, insert the ink-receiving inner barrel 9 into the water-based ink storage barrel 2, place the folded ink discharge pipe 7 on the receiving block 12, so that the first flange 10 and the second flange 11 are in contact, and the limiting block 14 is embedded in the limiting groove 16. The flange, the receiving block 12, and the fixing ring 13 are fixed by the screw. After injecting ink into the ink-receiving inner barrel 9, hold and pull the pull strap 611 to rotate and install the barrel cover 3, so that the limiting block 603 moves down along the limiting groove 605 until the first fixing block 606 and the second fixing block 607 are in contact. Screw the second screw 609 into the third screw sleeve 608 to complete the fixation. Disassembly is performed by reversing the operation.

[0023] Start the dual-head motor 501, which drives the transmission gear 503 to rotate, causing the drive screw 504 to rotate. The first sliding block 505, through the threaded transmission of the first threaded sleeve 506, causes the second slider 508 to move in opposite directions within the first sliding groove 507. The hinge rod 509 gradually becomes vertical and pushes the pressure movable disc 4 downward, discharging the ink from the upper end of the folded ink discharge pipe 7. When cleaning the ink-receiving inner tank 9, the ink must first be drained. Cleaning fluid is then injected through the connecting water pipe 515, driving the pressure movable disc 4 to reciprocate within the ink-receiving inner tank 9.

[0024] During ink discharge, pulling the connecting rod 817 rotates the first sealing disc 802, releasing the seal of the mounting box 801. The gear set, consisting of the first gear 808, second gear 813, third gear 814, fourth gear 815, and fifth gear 816, drives the second gear 813 to move the rack 810, opening the end of the folded ink discharge tube 7. After releasing the connecting rod 817, the torsion spring 807 drives the first sealing disc 802 to reset, while the second sealing disc 809 closes simultaneously, achieving a double seal on the folded ink discharge tube 7.
