Description

Technical Field

[0001] The invention relates to the field of printing technology, and more particularly to an ink heating module of an ink circulation system. Background Art

[0002] In inkjet printing, the viscosity parameters of the ink are crucial, because each type of nozzle has a viscosity range requirement for the ink used. For example, the Seiko circulating nozzle requires the ink viscosity range at the nozzle to be 7-17cp, while the Xaar circulating nozzle requires it to be 7-25cp. When the ink viscosity exceeds the required range, problems such as ink breakage and ink leakage are prone to occur, resulting in poor printing quality. Temperature is the main factor affecting viscosity.

[0003] To solve the above problems, the prior art generally adds a heating module for controlling the ink temperature in a traditional circulating ink supply system, such as the utility model patent with announcement number CN213891837U, an ink heating device for an ink supply pipeline and an inkjet printing device. In the public document, the viscosity of the ink is controlled by heating and dissipating the ink. However, when heating the ink, if the water content of the ink is high, the water in the ink will evaporate due to the heat to form water vapor. These water vapors form bubbles and mix into the ink. When inkjet printing is performed, the bubbles may block some nozzles of the nozzle, resulting in the inability to spray ink at the corresponding position during the printing process, thereby causing blank stripes to appear on the printed product, affecting the integrity and clarity of the image or text. The bubbles will also interfere with the normal injection amount and injection direction of the ink, causing uneven injection of inks of different colors, resulting in different shades of printed colors and unnatural transitions, which seriously reduces the printing quality.

[0004] In view of this, in view of the above-mentioned deficiencies, the present invention improves and optimizes the ink circulation heating module in the above-mentioned technology, and develops an ink heating module for an ink circulation system. Summary of the invention

[0070] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0071] See also Figures 1 to 14 The present invention provides a technical solution for an ink heating module of an ink circulation system:

[0072] An ink heating module of an ink circulation system comprises a lower fixed block 1 and an upper fixed block 2, wherein the upper fixed block 2 is arranged above the lower fixed block 1; a mounting groove 3, wherein the mounting groove 3 is arranged on the adjacent surfaces of the lower fixed block 1 and the upper fixed block 2; a heating tube 4, wherein the heating tube 4 is arranged in multiple groups, wherein the heating tube 4 is arranged between the lower fixed block 1 and the upper fixed block 2, and both upper and lower ends of the heating tube 4 can be plugged into the corresponding mounting groove 3; a liquid inlet 5, wherein the liquid inlet 5 is arranged on the side surface of the lower fixed block 1, and the liquid inlet 5 is communicated with the corresponding mounting groove 3; a liquid outlet 6, wherein the liquid outlet 6 is arranged on the side surface of the lower fixed block 1, and the liquid outlet 6 is communicated with the corresponding mounting groove 3; a circulation cavity 8, wherein the circulation cavity 8 is arranged inside the upper fixed block 2, and the inside of the circulation cavity 8 is communicated with the mounting groove 3 on the upper fixed block 2; a degassing component, wherein the degassing component is used to remove bubbles in the ink, wherein the degassing component is arranged on the top of the upper fixed block 2, and the degassing component comprises an air collecting cover 9, and the inside of the air collecting cover 9 is communicated with the inside of the circulation cavity 8;

[0073] A temperature sensor 41 is installed on the lower fixed block 1. The number of the temperature sensors 41 corresponds to the number of the mounting grooves 3 provided on the lower fixed block 1. The detection end of the temperature sensor 41 extends into the mounting groove 3. A temperature switch 40 is installed on the outside of the heating tube 4. The temperature switch 40 is used to turn on and off the operation of the heating tube 4.

[0074] When in use, first insert the two ends of the heating tube 4 into the corresponding mounting groove 3, then pass the screw 34 through the threaded holes on the upper fixing block 2 and the lower fixing block 1, finally tighten the nut 36, then clamp the conductive clamp 38 on the electrodes at both ends of the heating tube 4, use screws to fix the conductive voltage plate 37 on the conductive clamp 38, then cover the outside of the heating tube 4 with two sets of protective covers 35, use screws to fix the protective covers 35 on the corresponding upper fixing block 2 and the lower fixing block 1, one set of protective covers 35 is installed with a protective coil 39, use a wire to pass through the corresponding protective coil 39, and fix it with the corresponding conductive voltage plate 37, then connect the quick connector 7 to the input ink tube, connect the input ink tube to the liquid inlet 5 through the quick connector 7, and connect the output ink tube to the liquid outlet 6 by using the quick connector 7. The ink will enter from the liquid inlet 5 and flow along the corresponding heating tube 4, and finally flow into the circulation cavity 8, and flow from the right end of the circulation cavity 8 to the left end. The ink flows into the heating tube 4 at the left end and flows along the heating tube 4. When it flows to the liquid outlet 6, it flows into the output ink tube. The present invention is externally provided with a controller. The heating tube 4, the temperature switch 40 and the temperature sensor 41 are all electrically connected to the controller. When the ink flows from the heating tube 4, the temperature switch 40 is controlled by the controller, and then the heating tube 4 is controlled to generate heat by the temperature switch 40. The heating tube 4 heats the ink flowing inside during the heating process. The water in the ink turns into steam after heating, forming bubbles that flow with the ink. The bubbles flow into the circulation cavity 8 with the ink. The larger bubbles are subject to greater buoyancy and move along the upper inner wall of the circulation cavity 8 in the circulation cavity 8. An air collecting hood 9 is installed directly above the upper fixed block 2. When the bubbles flow to the bottom of the air collecting hood 9, the large bubbles float up and enter the air collecting hood 9. The bubbles that enter the air collecting hood 9 are restricted by the air collecting hood 9 and no longer flow with the ink, thereby removing the bubbles in the ink.

[0075] In addition, the temperature of the ink can be detected by the installed temperature sensor 41, so as to avoid the problem of the ink being heated to too high a temperature and being damaged.

[0076] In some embodiments, the degassing assembly also includes a float 10, which is arranged in the gas collecting hood 9, and the side surface of the float 10 is attached to the inner wall of the gas collecting hood 9. The float 10 is made of low-density material or has a hollow structure design; an air guide groove 42, which is vertically penetrated and opened on the float 10; a push rod 11, which is fixedly connected to the upper surface of the float 10, and the upper end of the push rod 11 is initially in contact with the inner wall of the upper end of the gas collecting hood 9; a sealing rod 12, which is fixedly installed on the side surface of the push rod 11; an exhaust pipe 14, which can be contacted and arranged at the end of the sealing rod 12 away from the push rod 11, and the end of the exhaust pipe 14 away from the sealing rod 12 passes through the side wall of the gas collecting hood 9 and extends to the outside; a first spring 13, which is wound around the side surfaces of the sealing rod 12 and the exhaust pipe 14, the left end of the first spring 13 is fixedly connected to the sealing rod 12, and the right end of the first spring 13 is fixedly connected to the exhaust pipe 14.

[0077] When the gas in the gas collecting hood 9 gathers more and more, the air pressure in the gas collecting hood 9 will increase, and the air pressure will squeeze the liquid level in the gas collecting hood 9 to move downward. The overall density of the floating block 10 is lower than the density of the ink, and it can be suspended on the ink. When the liquid level is lower than the floating block 10 and continues to move downward, the floating block 10 will also move downward with the liquid level due to its own gravity. When the floating block 10 moves downward, it will drive the sealing rod 12 to move downward synchronously. When the sealing rod 12 moves downward, it will bend the first spring 13 and open the opening at the left end of the exhaust pipe 14 at the same time. The air in the air collecting hood 9 will be discharged through the exhaust pipe 14. When the air pressure in the air collecting hood 9 decreases, the liquid level in the air collecting hood 9 will rise, and the floating block 10 will also rise. When the floating block 10 rises, it will drive the sealing rod 12 to rise synchronously. Finally, the sealing rod 12 seals the left end opening of the exhaust pipe 14 to prevent liquid from being discharged from the exhaust pipe 14. Installing the first spring 13 can prevent the sealing rod 12 from being misaligned with the opening at the left end of the exhaust pipe 14 when the floating block 10 moves up and down.

[0078] In some embodiments, the lower end of the floating block 10 is designed to be hemispherical.

[0079] By adopting the above technical solution, when the bubbles move to the bottom of the air collecting cover 9 , the bottom of the floating block 10 is designed to be hemispherical, which facilitates the bubbles to move upward along the arc surface and enter the air guide groove 42 .

[0080] In some embodiments, the degassing assembly also includes a filter plate 15, which is installed in the circulation chamber 8. The filter plate 15 is arranged at the left side of the gas collecting hood 9. The filter plate 15 is made of a hard filamentary material, and the internal structure of the filter plate 15 is tightly designed; a support plate 16, which is fixedly installed on the left side of the filter plate 15; a circulation hole 17, which is arranged in multiple groups, and the circulation hole 17 is opened through the side wall of the support plate 16; an elastic membrane 23, which is fixedly connected to the edge of the support plate 16, and the end of the elastic membrane 23 away from the support plate 16 is fixedly connected to the inner wall of the circulation chamber 8.

[0081] Small bubbles in the ink have small buoyancy and can easily move with the flowing ink. For this reason, the present invention sets a filter plate 15. Because the filter plate 15 is made of hard filamentary material and the internal structure of the filter plate 15 is relatively tight, the ink can pass through the filter plate 15. The tight structure of the filter plate 15 will form many tiny channels and pores. Since the small bubbles have certain elasticity and compressibility, the small bubbles need to overcome the surface tension and adsorption force of the filamentary material in the process of passing through the filter plate 15, which makes it difficult for the small bubbles to pass through easily. Because the filamentary material is made of hard material, it is difficult for the bubbles to squeeze the filamentary material to deform and change the size of the channel gap. By installing the filter plate 15, small bubbles and some impurities in the ink can be filtered to purify the ink. In addition, the installed support plate 16 plays a role in supporting the filter plate 15, and the opened flow hole 17 is used to ensure the circulation of ink.

[0082] In some embodiments, the degassing assembly also includes a rotating shaft 18, which is arranged on the left side of the support plate 16, and both ends of the rotating shaft 18 are rotatably connected to the inner wall of the flow chamber 8; paddle blades 19, which are arranged in multiple groups, and the multiple groups of paddle blades 19 are evenly installed on the side surface of the rotating shaft 18, and the multiple groups of paddle blades 19 are distributed in a ring shape; a first permanent magnet block 20, which is arranged in multiple groups, and the multiple groups of first permanent magnet blocks 20 are distributed in a ring shape, and the first permanent magnet block 20 is installed on the side surface of the rotating shaft 18; a second permanent magnet block 21, which is installed on the side surface of the support plate 16 and on the adjacent surface of the support plate 16 and the rotating shaft 18, and the installation position of the second permanent magnet block 21 corresponds to the installation position of the first permanent magnet block 20.

[0083] The tension between the filter plate 15 and the small bubbles will cause the small bubbles to adhere to the filter plate 15, thereby blocking the filter plate 15 and affecting the filtering efficiency of the filter plate 15. In this invention, when the ink passes through the circulation hole 17, the ink will push the paddle blade 19 to drive the rotating shaft 18 to rotate. When the rotating shaft 18 rotates, it will drive the first permanent magnet block 20 to rotate. When the first permanent magnet block 20 rotates, it will intermittently pass by the second permanent magnet block 21. Whether the first permanent magnet block 20 and the second permanent magnet block 21 are set to attract or repel each other, in the first When the permanent magnet block 20 passes by the second permanent magnet block 21, it can exert a magnetic force on the second permanent magnet block 21, thereby driving the second permanent magnet block 21 to move. When the second permanent magnet block 21 moves, it will drive the support plate 16 and the filter plate 15 to move together. In this way, the filter plate 15 will continue to shake, causing the bubbles to detach from the filter plate 15. The detached bubbles move upward with their own buoyancy and finally enter the air collecting hood 9. When the filter plate 15 shakes, the impurities filtered on the surface will fall off, thereby avoiding clogging of the filter plate 15.

[0084] In some embodiments, the degassing assembly further includes a limit plate 22, which is disposed at the sides of the upper and lower ends of the support plate 16 and the filter plate 15, and the limit plate 22 is fixedly connected to the inner wall of the flow chamber 8;

[0085] The scraping strips 33 are provided in multiple groups, and the multiple groups of scraping strips 33 are arranged from bottom to top. The scraping strips 33 are fitted on the side surface of the filter plate 15 , and the scraping strips 33 are fixedly connected to the inner wall of the flow chamber 8 .

[0086] When the filter plate 15 is shaking, it is restricted by the limit plate 22, so that the filter plate 15 can only shake vertically up and down. In this way, when the filter plate 15 is shaking up and down, the scraper strip 33 will continuously scrape the filter plate 15 passing through, which can remove the more stubborn impurities adhered to the surface of the filter plate 15, thereby effectively filtering the impurities on the surface of the filter plate 15.

[0087] In some embodiments, it includes a groove 25, which is opened on the inner wall of the flow chamber 8 and is close to the filter plate 15; a slag guide plate 24, which is installed on the side surface of the filter plate 15 near the bottom, and the slag guide plate 24 is designed with an arc-shaped structure. The slag guide plate 24 is inclined and inclined toward the groove 25, and one end of the slag guide plate 24 extends to the inside of the groove 25; a slag discharge hole 26, which is opened on the side wall of the groove 25 near the lower end, and the groove 25 is connected to the outside of the upper fixed block 2 through the slag discharge hole 26; a slag discharge pipe 27, which is fixedly installed on the side surface of the upper fixed block 2 and at a position corresponding to the slag discharge hole 26; a collecting box 28, which is installed at the lower end of the slag discharge pipe 27.

[0088] The impurities that fall off the filter plate 15 will fall onto the slag guide plate 24. The impurities will move to the groove 25 along the inclination of the slag guide plate 24, and finally enter the slag discharge pipe 27 through the slag discharge hole 26, and enter the collection box 28 along the slag discharge pipe 27, thereby realizing automatic collection of impurities. When the filter plate 15 shakes up and down, it will also drive the slag guide plate 24 to shake synchronously, which also makes it easier for the impurities in the slag guide plate 24 to move downward along the slope of the slag guide plate 24, thereby improving the efficiency of the collection box 28 in collecting impurities.

[0089] In some embodiments, it includes a sealing plate 29, which is slidably disposed inside the groove 25, and the initial position of the sealing plate 29 covers the slag discharge hole 26; a telescopic rod 30, which is fixedly installed on the upper end of the sealing plate 29; a sleeve 32, which is sleeved on the outside of the telescopic rod 30, and the telescopic rod 30 can be sealed and slid inside the sleeve 32; a second spring 31, which is disposed inside the sleeve 32, and the upper end of the second spring 31 is fixedly connected to the inner top wall of the sleeve 32, and the lower end of the second spring 31 is fixedly connected to the telescopic rod 30.

[0090] By adopting the above technical solution, when ink is supplied by the water pump, the pressure in the circulation chamber 8 will be greater than the pressure in the sleeve 32. The sleeve 32 is at atmospheric pressure under normal circumstances. Due to the pressure difference, the telescopic rod 30 will extend upward into the sleeve 32 and squeeze the second spring 31. When the telescopic rod 30 moves upward, it will drive the sealing plate 29 to move synchronously, so that the sealing plate 29 will open the slag discharge hole 26 to facilitate impurities to enter the slag discharge hole 26. After the ink supply is completed, the ink in the circulation chamber 8 is in a static state, and the pressure in the circulation chamber 8 is the same as the pressure in the sleeve 32. The second spring 31 pushes the telescopic rod 30 to move downward, and finally the sealing plate 29 closes the slag discharge hole 26 to prevent impurities in the collection box 28 from flowing back into the circulation chamber 8.

[0091] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
