Description

Technical Field

[0001] This utility model relates to the field of printing equipment, specifically a split-type gravure printing and drying integrated machine. Background Technology

[0002] Gravure printing is a printing process where the image areas of the printing plate are recessed. After removing excess ink from the surface of the printing plate with a doctor blade, pressure is used to transfer the ink from the recessed areas to the surface of the substrate. It produces a thick ink layer, vibrant colors, and strong printing durability, and is suitable for materials such as paper, plastic film, and metal foil. It is widely used in packaging printing and mass production.

A connecting rod 9 is welded to the other side of the connecting plate 8 and fixedly connected to the back of the split-type electric heating radiation plate 6. The split-type electric heating radiation plate 6 is easy to disassemble and maintain. In addition, the split-type electric heating radiation plate 6 can approach and move away from the gravure-printed carrier 4 to assist in adjusting the drying temperature, and the temperature adjustment range is wide.

[0022] The top of the box 1 is fixedly connected to the mounting plate 2 by bolts above the pressure roller 21. The bottom of the mounting plate 2 is connected to the preheating fan 3 by bolts. The side of the preheating fan 3 is provided with a bidirectional air outlet 20 to preheat the non-printing surface of the printing carrier 4 before and after gravure printing, increase the temperature of the printing carrier 4, and accelerate the drying speed of the ink. Among them, a lifting plate groove 11 is provided between the first connecting base 23 and the second connecting base 28, a lifting push rod 29 is provided at the bottom center of the box body 1, the output end of the lifting push rod 29 is fixedly connected to the lifting plate 30, guide rods 33 are provided on both sides of the bottom of the lifting plate 30 and are slidably connected to the bottom of the box body 1, the lifting plate 30 is slidably connected to the lifting plate groove 11, changing the height of the ink tank 31 so that the gravure roller 22 can always be in full contact with the ink; The box body 1 has an inlet 10 on the side where the adjusting push rod 5 is located, corresponding to the position of the lifting plate sink 11, which facilitates the addition of ink to the ink tank 31 and makes it easy to use. Among them, the two sides of the split-type electric heating radiation plate 6 are welded with connecting wing plates 32, which are slidably connected to the guide rail 7 to improve the smoothness of sliding of the split-type electric heating radiation plate 6. Among them, a U-shaped insulation board 26 is fixedly connected to the inner side of the guide rail 7 on the box 1 by bolts to increase the temperature of the drying environment.

Among them, the top of the second connecting base 28 is fixedly connected to the side of the gravure roller 22 by bolts with a "Z"-shaped heat insulation cover plate 27 to prevent the temperature of the split electric heating radiation plate 6 from causing the ink in the ink tank 31 to solidify. The bottom of the scraper 24 is vertically and evenly distributed with multiple guide bars 25. The guide bars 25 are located inside the ink tank 31, and the ink scraped off by the scraper 24 is sent into the ink tank 31 through the guide bars 25 for recycling. Among them, a sealed stirring motor 35 is bolted to the bottom center of the ink tank 31. The stirring motor 35 is powered by a battery. The output end of the stirring motor 35 is equipped with stirring blades 36 to slow down the solidification speed of the ink in the ink tank 31. A recessed handle 34 is provided on the end face of the ink tank 31 to prevent the ink tank 31 from interfering with the inner wall of the box 1 when it slides. The bottom of the box 1 is welded with four mounting feet 12. The bottom plate of the mounting feet 12 is provided with through holes to facilitate fixed connection with the ground. The installation is convenient and the fixation is firm.

[0023] The working principle of this utility model is as follows: During gravure printing, the printing carrier 4 passes sequentially through the gap between the first guide roller 14, the second guide roller 15, the pressure roller 21 and the gravure roller 22, the fourth guide roller 18 and the third guide roller 17, and then leaves the box 1 through the discharge support plate 19. As the gravure roller 22 rotates, it coats the gravure pattern with ink as it passes through the ink tank 31. Then, the excess ink is scraped off by the doctor blade 24. Finally, the pressure roller 21 transfers the ink from the gravure pattern onto the printing carrier 4 to complete the gravure printing. During the ink scraping process, the scraped ink flows along the guide bar 25 into the ink tank 31 for recycling, saving resources. When the ink depth in the ink tank 31 reaches a certain point, the lifting push rod 29 moves the lifting plate 30 and the ink tank 31 upwards together, ensuring that the gravure roller 22 is always fully immersed in the ink, improving printing quality. During the gravure printing process, the stirring motor 35 in the ink tank 31 drives the stirring blades 36 to slow down the ink solidification rate, improving printing quality. During the gravure printing process, the pre-stirring roller located at the top of the pressure roller 21... The hot air blower 3 preheats the non-printing surface of the printing carrier 4 before and after gravure printing, increasing the temperature of the printing carrier 4, accelerating the drying speed of the ink, and improving work efficiency. During the process of the printing surface after gravure printing moving from the fourth guide roller 18 to the third guide roller 17, the split-type electric heating radiation plate 6 dries the printing surface of the printing carrier 4. By setting the extension and retraction of the adjusting push rod 5, the split-type electric heating radiation plate 6 can be moved closer to or away from the printing carrier 4 by the connecting plate 8 and the connecting rod 9, which can adjust the drying temperature. Combined with the temperature adjustment function of the split-type electric heating radiation plate 6 itself, the adjustment range is wide and the drying control is more precise, ensuring that the ink on the printing carrier 4 is completely dried and improving printing quality. When it is necessary to add ink to the ink tank 31, the lifting plate 30 descends until it is completely submerged in the lifting plate sink 11. Pulling the recessed handle 34 on the ink tank 31 pulls a portion of the ink tank 31 out from the feed port 10 to replenish the ink. The ink tank 31 can also be easily pulled out through the feed port 10 for cleaning, making it convenient to use.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
