Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water-based ink discharging, in particular to a device facilitating water-based ink discharging. BACKGROUND

[0002] Water-based ink, also known as water ink, is a printing ink system with water as the main solvent or dispersion medium. It is mainly composed of water-soluble resin, organic pigment, solvent and related additives processed by compounding and grinding. The water-soluble resin in water-based ink serves as a connecting material, allowing the uniform dispersion of pigment particles, the flowability of ink, and the adhesion to the printing material. The pigment gives the ink its color. The solvent, mainly water and a small amount of ethanol, is used to dissolve the resin and adjust the flowability, viscosity and drying performance of the ink. The additives include defoamers, pH stabilizers, slow-drying agents, etc., which respectively serve to suppress and eliminate bubbles, adjust and control pH and viscosity, and inhibit and slow down the drying speed.

[0003] The water-based ink is generally taken by a scraper or placed in a barrel with a valve. The valve is opened to take the water-based ink by gravity. However, this method has the following disadvantages: first, as the total amount of water-based ink in the barrel decreases, the flow rate of water-based ink discharged from the valve also decreases, making it difficult for the worker to control the amount of water-based ink taken out; second, water-based ink is prone to remain at the valve, thereby contaminating the surrounding environment and affecting the normal discharge of water-based ink. Moreover, when changing to a different color of water-based ink, the barrel needs to be cleaned, which is troublesome and time-consuming. SUMMARY

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Please refer to Figures 1-10 The present application provides a technical solution: a device for facilitating water-based ink discharging, comprising a fixed base 1, a water-based ink placing barrel 2 fixedly installed on the upper side of the fixed base 1, an installation barrel cover 3 installed on the upper side of the water-based ink placing barrel 2, a pressure movable disc 4 movably installed on the lower side of the installation barrel cover 3, a backfolding ink discharge pipe 7 installed on the lower side of the water-based ink placing barrel 2, and an ink receiving inner barrel 9 installed in the water-based ink placing barrel 2.

[0033] The driving cleaning mechanism 5 includes a double-head motor 501, a first sliding groove 507, a second sliding block 508, and a hinged rod 509. The upper side of the installation bucket cover 3 is fixedly installed with the double-head motor 501. Two groups of first sliding grooves 507 are opened on the installation bucket cover 3. The second sliding block 508 is movably installed in the first sliding groove 507. The lower side of the two groups of second sliding blocks 508 is hingedly connected with the hinged rod 509. One end of the hinged rod 509 is hingedly connected to the upper side of the pressure movable disc 4.

[0034] The rotating mechanism 6 includes a fixed side plate 601, a movable insertion rod 602, and an insertion cylinder 604. One end of the installation bucket cover 3 is fixedly installed with the fixed side plate 601. The lower side of the fixed side plate 601 is fixedly installed with the movable insertion rod 602. One side of the water-based ink placing barrel 2 is fixedly installed with the insertion cylinder 604. The movable insertion rod 602 is movably inserted into the insertion cylinder 604.

[0035] The double sealing mechanism 8 includes an installation box 801, a first sealing circular plate 802, and a second sealing circular plate 809. The installation box 801 is fixedly installed at the end of the backfolding ink discharge pipe 7 and communicates with the backfolding ink discharge pipe 7. The first sealing circular plate 802 is movably installed in the installation box 801. The second sealing circular plate 809 is movably installed at the lower side of the end of the backfolding ink discharge pipe 7. The device pressurizes the ink in the water-based ink placing barrel 2 by sealing and pressing. The ink is discharged at the end of the backfolding ink discharge pipe 7 through the action of the communicating vessel, so as to realize the quantitative discharge of the ink in the water-based ink placing barrel 2. In the case that the pressure movable disc 4 is not active, the ink will not be discharged, which increases the stability of the device during use. The device is equipped with a replaceable ink containing inner barrel 9 and a backfolding ink discharge pipe 7, so that different colors and types of ink in the water-based ink placing barrel 2 can be quickly replaced, which increases the functionality and convenience of the device during use. The device is also equipped with a double sealing mechanism 8 at the end of the backfolding ink discharge pipe 7, so that the ink discharged from the backfolding ink discharge pipe 7 is less residual and is not easy to condense and block. In the case that the double sealing mechanism 8 is opened, the pressure movable disc 4 does not pressurize the ink in the water-based ink placing barrel 2, and the backfolding ink discharge pipe 7 does not discharge the ink, so that the end of the backfolding ink discharge pipe 7 is easy to clean, which increases the convenience of cleaning the device.

[0036] Further, the driving cleaning mechanism 5 further comprises two groups of installation side plates 502, transmission gears 503, driving screws 504, first sliding blocks 505, first screw sleeves 506, rolling wheels 510 and a first shielding box 525. Two groups of installation side plates 502 are fixedly installed on the installation lid 3. The outer sides of the installation side plates 502 are arrayed with transmission gears 503 which are rotatably installed. The output shaft of the double-head motor 501 is fixedly connected with the central transmission gear 503. The transmission gears 503 are meshed with each other. Two groups of driving screws 504 are rotatably installed between the installation side plates 502. The threads on the driving screws 504 are opposite. The two ends of the driving screws 504 are fixedly connected with the outer transmission gears 503. Two groups of first sliding blocks 505 are movably installed between the installation side plates 502. The central positions of the first sliding blocks 505 are fixedly installed with first screw sleeves 506. The first screw sleeves 506 are threadedly sleeved on the driving screws 504. The two groups of first sliding blocks 505 are fixedly installed on the second sliding blocks 508 respectively. The first shielding box 525 is fixedly installed on the installation lid 3. The installation side plates 502 are fixedly installed in the first shielding box 525. The schematic diagram of the structure is as follows. Figure 4 The number of the transmission gears 503 installed on the same group of installation side plates 502 is odd. Therefore, the driving screws 504 can rotate in the same direction. However, the threads on the two groups of driving screws 504 are opposite. Therefore, the two groups of first sliding blocks 505 can move in opposite directions under the driving of the driving screws 504. The structure synchronizes the rotating speed and rotating time of the driving screws 504. Therefore, the pressure movable disc 4 can be stably driven to descend, thereby increasing the stability during use of the equipment.

[0037] Further, the driving cleaning mechanism 5 further comprises second sliding grooves 511, guide rods 512 and guide holes 513. The two sides of the first sliding groove 507 are provided with the second sliding grooves 511. The two sides of the second sliding block 508 are rotatably installed with the rolling wheels 510. The rolling wheels 510 roll in the second sliding grooves 511. The first sliding groove 507 is fixedly installed with the guide rods 512. The second sliding block 508 is provided with the guide holes 513. The guide rods 512 are movably inserted into the guide holes 513. The schematic diagram of the structure is as follows. Figure 4 and Figure 5 The length of the hinged rod 509 is matched with the height of the water-based ink placing barrel 2. During use, the pressure movable disc 4 does not completely contact with the bottom surface of the water-based ink placing barrel 2. When the ink is placed in the ink containing inner barrel 9, the ink is not completely filled, so that an air layer is formed between the upper layer of the ink and the ink scraping plate 521. When the pressure movable disc 4 is pressed, the air can extrude the ink, thereby reducing the pollution of the pressure movable disc 4 by the ink and improving the cleaning convenience of the equipment. The two groups of hinged rods 509 and the hinged positions on the upper side of the pressure movable disc 4 are symmetrically distributed along the center point of the pressure movable disc 4, thereby effectively ensuring the stability when the pressure movable disc 4 descends. The rolling wheels 510 can significantly reduce the resistance when the second sliding block 508 moves;

[0038] Further, the driving cleaning mechanism 5 further comprises an insertion slot 514, a connecting water pipe 515, a threaded joint 516, an annular water groove 517, a drain hole 518 and a threaded water port 519. The insertion slot 514 is arranged on one side of the installation bucket cover 3. The connecting water pipe 515 is movably arranged in the insertion slot 514. The threaded joint 516 is fixedly arranged on the lower side of the connecting water pipe 515. The annular water groove 517 is arranged on the pressure movable disc 4. The drain hole 518 is arranged on the pressure movable disc 4 in an array. The drain hole 518 is in communication with the annular water groove 517. The threaded water port 519 is fixedly arranged on the upper side of the installation bucket cover 3. The threaded water port 519 is in communication with the annular water groove 517. The threaded joint 516 is threadedly sleeved on the threaded water port 519. The schematic diagram of the structure is as follows. Figure 3 and Figure 6 The length of the connecting water pipe 515 is adapted to the movement process of the pressure movable disc 4. When the ink storage inner bucket 9 does not store ink, the cleaning liquid can be injected into the ink storage inner bucket 9 through the connecting water pipe 515. The inner wall of the ink storage inner bucket 9 is cleaned by the up-down movement of the pressure movable disc 4. The cleaning efficiency of the equipment is improved. The structure does not affect the normal operation of the pressure movable disc 4.

[0039] Further, the driving cleaning mechanism 5 further comprises a first sealing rubber ring 520, an ink scraping plate 521, an insertion hole 522, a first screw rod 523 and a second screw sleeve 524. The first sealing rubber ring 520 is fixedly arranged on the upper side edge of the pressure movable disc 4. The outer side of the first sealing rubber ring 520 is tightly attached to the inner wall of the ink storage inner bucket 9. The ink scraping plate 521 is sleeved on the lower side of the pressure movable disc 4. The edge of the ink scraping plate 521 is attached to the inner wall of the ink storage inner bucket 9.

Two groups of second screw sleeves 524 are fixedly arranged on the lower side of the pressure movable disc 4. The first screw rod 523 is threadedly arranged in the second screw sleeve 524. The schematic diagram of the structure is as follows. Figure 6 By the sealing effect of the first sealing rubber ring 520, the pressure movable disc 4 can be pressed down by the air layer between the ink in the ink storage inner bucket 9 and the ink scraping plate 521, thereby reducing the pollution of the ink to the pressure movable disc 4. At the same time, the ink scraping plate 521 can scrape the inner wall of the ink storage inner bucket 9, which improves the use efficiency of the ink and reduces the cleaning difficulty of the ink storage inner bucket 9. The drain hole 518 is arranged between the first sealing rubber ring 520 and the ink scraping plate 521, so that the sprayed cleaning liquid can be stored in this area. When the pressure movable disc 4 moves up and down, the cleaning liquid can fully contact the inner wall of the ink storage inner bucket 9, thereby improving the cleaning efficiency of the equipment.
