Description

Technical Field

[0001] This utility model relates to the field of ink printing technology, and in particular to a device for uniform ink distribution in a color printing machine. Background Technology

[0002] In today's printing industry, color printing plays a vital role and is widely used in packaging, promotional materials, and art prints for various products. As the market's requirements for the quality of printed materials continue to increase, especially for the color accuracy, pattern clarity, and overall aesthetics of color printing, uniform ink distribution has become a key factor in color printing.

[0003] In traditional color printing, ink often faces several problems during storage. Due to the long storage time required, ink is susceptible to solidification and stratification due to environmental factors such as temperature and humidity. When ink solidifies and stratifies, it directly leads to a series of quality issues during the printing process. For example, uneven ink application results in inconsistent ink thickness on the printed product, with some areas having thicker ink and others thinner. This thickness difference further leads to color deviation, making it difficult to accurately reproduce the color requirements of the design and severely affecting the visual effect and quality of the printed product. Furthermore, after inkjet printing, the ink on the printing plate surface may be unevenly distributed, with some areas having excessive ink. If excessive ink is not addressed, it not only affects the appearance quality of the printed product but may also lead to prolonged ink drying time and ink dripping, further impacting printing production efficiency and the final product quality. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a device for uniform ink distribution in a color printing machine.

[0006] The scraper mechanism includes a support, a motor is fixedly installed inside the support, a lead screw is fixedly connected to the output end of the motor, a transmission frame is threadedly connected to the surface of the lead screw, a scraper is fixedly connected to the surface of the transmission frame, a limit rod passes through both sides of the transmission frame, a shaft seat is rotatably connected to the surface of the lead screw, and a seat is fixedly connected to both ends of the limit rod.

[0007] The above technical solution ensures that the ink is evenly stirred before spraying and further evenly distributed by the scraper mechanism after spraying, effectively ensuring the uniformity of the ink throughout the printing process, improving printing quality, and the setting of the ink recycling box can recycle excess ink, reduce ink waste, and save costs.

[0008] As a further improvement to the above solution, a bracket is fixedly connected to the upper surface of the processing table, and a motor is fixedly installed inside the bracket.

[0009] As a further improvement to the above solution, the output end of the second motor is fixedly connected to the second lead screw, and the surface of the second lead screw is rotatably connected to a rotating seat.

[0010] As a further improvement to the above solution, a transmission block is threadedly connected to the surface of the lead screw, and a mounting box is fixedly connected to the surface of the transmission block.

[0011] As a further improvement to the above solution, a vacuum pump is fixedly connected to the inner wall of the mounting box, and a negative pressure suction cup is fixedly connected to the input end of the vacuum pump. A printed plate is provided on the surface of the negative pressure suction cup.

[0012] The above technical solutions ensure the stability of the printing plate during the subsequent ink coating process, prevent the printing plate from moving, guarantee the accuracy and uniformity of ink spraying, and improve the quality of the printed products.

[0013] As a further improvement to the above solution, both ends of the mounting box are fixedly connected to extension sleeves, and the extension sleeves are provided with limit rods two inside, which are fixedly connected to the inner wall of the ink recycling frame.

[0014] Through the above technical solution, the limiting rod 2 provides guidance for the movement of the mounting box, ensuring that the printing plate can accurately enter under the inkjet nozzle to receive ink spraying, thereby improving the accuracy and stability of the entire printing process.

[0015] As a further improvement to the above solution, a pad is fixedly connected to the upper surface of the processing table, a hot air blower is fixedly connected to the upper surface of the pad, and a filter screen is fixedly connected to the input end of the hot air blower.

[0016] The above technical solutions accelerate ink forming speed and improve printing production efficiency. At the same time, the filter screen can prevent dust and other impurities from entering the hot air blower, ensuring the normal operation of the hot air blower and the drying effect.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention uses a drive motor to rotate a stirring rod, which agitates the ink in the ink tank, ensuring its uniformity. This avoids ink solidification and stratification caused by prolonged storage, which can lead to inconsistent coating thickness and color deviations in subsequent printing. After inkjet printing, the motor drives a lead screw to rotate, causing the transmission frame to move along a limit rod. The doctor blade, following the movement of the transmission frame, scrapes off excess ink from the printing plate surface. Simultaneously, the movement of the doctor blade further ensures uniform ink distribution on the printing plate surface. This dual approach ensures ink uniformity throughout the printing process. Stirring guarantees ink uniformity from the source, while the doctor blade performs a secondary adjustment and optimization of ink uniformity after inkjet printing, improving overall printing quality.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Example:

[0032] Please combine Figure 1-9 This embodiment of an ink uniform distribution device for a color printing machine includes a processing table 1, a support plate 2 fixedly connected to the surface of the processing table 1, a mounting frame 3 fixedly connected to the upper surface of the support plate 2, an ink tank 4 fixedly connected to the upper surface of the mounting frame 3, a drive motor 5 fixedly connected to the surface of the ink tank 4, a stirring rod 6 fixedly connected to the output end of the drive motor 5, an ink pump 7 fixedly connected to the upper surface of the mounting frame 3, a guide pipe 8 fixedly connected to the output end of the ink pump 7, several ink nozzles 9 fixedly connected to the surface of the guide pipe 8, a support base 10 fixedly connected to the surface of the guide pipe 8, an ink recovery frame 11 fixedly connected to the upper surface of the processing table 1, and a scraper mechanism 12 provided on the upper surface of the processing table 1.

[0033] The scraper mechanism 12 includes a support 121, inside which a motor 122 is fixedly installed. A lead screw 123 is fixedly connected to the output end of the motor 122. A transmission frame 124 is threaded onto the surface of the lead screw 123. A scraper blade 125 is fixedly connected to the surface of the transmission frame 124. Limiting rods 126 pass through both sides of the transmission frame 124. A bearing seat 127 is rotatably connected to the surface of the lead screw 123. A base 128 is fixedly connected to both ends of the limiting rods 126. The drive motor 5 drives the stirring rod 6 to rotate, ensuring uniform mixing of the ink in the ink tank 4. During storage, the ink may solidify and separate due to external environmental factors; stirring prevents this, ensuring the uniformity of the ink in the ink fountain and providing a basis for subsequent uniform spraying. Provided, ink pump 7 draws ink from ink tank 4 and delivers it to inkjet nozzle 9 through guide pipe 8 for spraying. Guide pipe 8 is fixed by support base 10. At the same time, ink recovery frame 11 is set on processing table 1 to recover excess ink. Motor 122 in scraper mechanism 12 drives lead screw 123 to rotate. The rotation of lead screw 123 causes threaded transmission frame 124 to move. Limiting rods 126 on both sides of transmission frame 124 restrict its rotation, allowing it to only move in a straight line. As transmission frame 124 moves, scrape off excess ink from the surface of printing plate. Excess ink falls into processing table 1. The movement of scraper 125 can further distribute ink evenly and prevent local ink spraying from being too thick.

[0034] A bracket 13 is fixedly connected to the upper surface of the processing table 1. A motor 14 is fixedly installed inside the bracket 13. When the motor 14 rotates, the lead screw 15 rotates accordingly.

[0035] The output end of motor 214 is fixedly connected to lead screw 215, and the surface of lead screw 215 is rotatably connected to rotary seat 16.

[0036] A transmission block 17 is threadedly connected to the surface of the lead screw 15. A mounting box 18 is fixedly connected to the surface of the transmission block 17. When the lead screw 15 rotates, the transmission block 17 threadedly connected to its surface will move along the lead screw 15. The mounting box 18 is fixedly connected to the transmission block 17, thereby driving the mounting box 18 to move.

[0037] A vacuum pump 19 is fixedly connected to the inner wall of the mounting box 18. A negative pressure suction cup 20 is fixedly connected to the input end of the vacuum pump 19. A printed plate 21 is provided on the surface of the negative pressure suction cup 20. The vacuum pump 19 on the inner wall of the mounting box 18 uses the negative pressure suction cup 20 to adsorb and fix the printed plate 21. When the vacuum pump 19 is working, it creates a negative pressure inside the negative pressure suction cup 20, thereby tightly adsorbing the printed plate 21.

[0038] Both ends of the mounting box 18 are fixedly connected to extension sleeves 22. The extension sleeves 22 are provided with limit rods 23 inside. The limit rods 23 are fixedly connected to the inner wall of the ink recovery frame 11. The extension sleeves 22 at both ends of the mounting box 18 are fitted onto the limit rods 23. When the mounting box 18 moves, the extension sleeves 22 move along the limit rods 23, causing the printing plate 21 on the surface to enter below the inkjet nozzle 9 to receive ink spraying.

[0039] A pad 24 is fixedly connected to the upper surface of the processing table 1. A hot air blower 25 is fixedly connected to the upper surface of the pad 24. A filter screen 26 is fixedly connected to the input end of the hot air blower 25. When the hot air blower 25 on the pad 24 is working, the air is filtered by the filter screen 26 at the input end of the hot air blower 25. The hot air blown out by the hot air blower 25 dries the surface of the printed board 21 after spraying.

[0040] The implementation principle of the ink uniform distribution device for a color printing machine in this embodiment is as follows: First, the operator starts the drive motor 5 on the surface of the ink tank 4. The output end of the drive motor 5 drives the stirring rod 6 to rotate, stirring the ink in the ink tank 4 to make the ink mix evenly and avoid ink solidification and stratification due to external environmental factors, thereby ensuring the uniformity of the ink in the ink fountain and providing a prerequisite for subsequent uniform spraying. Next, the printing plate 21 is placed on the negative pressure suction cup 20, and the vacuum pump 19 on the inner wall of the mounting box 18 is started. The vacuum pump 19 works to create negative pressure inside the negative pressure suction cup 20. This allows the printing plate 21 to be firmly adhered, ensuring its stability during subsequent operations. The motor 14 inside the support 13 on the upper surface of the processing table 1 is then activated. The rotation of motor 14 drives the lead screw 15 to rotate. As the lead screw 15 rotates, the threaded transmission block 17 moves along it. The mounting box 18 is fixedly connected to the transmission block 17, thus moving the mounting box 18. The extension sleeves 22 at both ends of the mounting box 18 are fitted onto the limiting rod 23, and the extension sleeves 22 move along the limiting rod 23, causing the mounting box 18, with the printing plate 21 adhering to its surface, to enter the inkjet nozzle 9. The ink is sprayed onto the printing plate 21 from below. The ink pump 7 on the upper surface of the mounting frame 3 is activated, drawing ink from the ink tank 4 and delivering it through the guide pipe 8 to several inkjet nozzles 9. The guide pipe 8 is fixed by the support base 10. The inkjet nozzles 9 begin spraying ink onto the printing plate 21. Simultaneously, the ink recovery frame 11 on the processing table 1 is used to recover excess ink. Then, the motor 122 in the scraper mechanism 12 is activated. The motor 122 drives the lead screw 123 to rotate, causing the threaded transmission frame 124 to move. The transmission frame 124 is restricted on both sides by limit rods 126. The rotation can only perform linear motion. As the transmission frame 124 moves, the scraper 125 on the transmission frame 124 scrapes off excess ink from the surface of the printing plate 21. The excess ink falls into the processing table 1. Furthermore, the movement of the scraper 125 can further distribute the ink evenly and prevent local ink spraying from being too thick. Finally, the hot air blower 25 on the pad 24 on the upper surface of the processing table 1 is started. The input end of the hot air blower 25 has a filter screen 26 to filter the air. The hot air blower 25 blows hot air to dry the surface of the printed plate 21 after spraying, which speeds up the ink forming speed and improves the printing production efficiency.

[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
