[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0035] The utility model provides Figures 1 to 6 A multi-layer composite printing device shown in the figure includes two groups of printing boxes 1, and a printing chamber 11 and a drying chamber 12 are arranged inside the printing box 1. An inspection port 13 is opened at the left position of the front surface of the printing box 1, and an air inlet fan 14 is fixedly installed at the right position of the front surface of the printing box 1. A printing module is arranged inside the printing chamber 11, and the printing module includes an ink box 2, an ink tank 21, an ink guide plate 22, a scraper 23, an ink guide strip 24, a filter box 26, a filter screen 28, a printing roller 210 and an ink guide roller 211. A drying module is arranged inside the drying chamber 12, and the drying module includes an air inlet fan 14, a heating box 3, heat dissipation holes 31, a ventilation pipe 32, a fixing plate 33 and a heating copper wire 34. A sealing cover plate 4 is hinged on the upper side of the printing box 1, and the front and rear inner walls of the sealing cover plate 4 are rotatably connected to a pressure roller 41, and the pressure roller 41 is located on the upper side of the printing roller 210.
[0036] Among them, the internal structures of the two groups of printing boxes 1 are the same, and the corresponding printing rollers 210 can be replaced according to the pattern to be printed. During the printing process, the sealing cover 4 is first opened upward, and the substrate is installed on the upper side of the printing module, and then the sealing cover 4 is closed. At this time, the pressure roller 41 presses the surface of the substrate, so that the substrate is placed between the pressure roller 41 and the printing roller 210. As the substrate moves, the driving module drives the ink guide roller 211 and the printing roller 210 to rotate (the driving module is a common technical means and is not described here). The ink guide roller 211 transfers the ink to the surface of the printing roller 210, and the printing roller 210 prints the substrate. As the substrate moves to the right, the printed substrate will pass through the upper side of the drying chamber 12. At this time, the drying module dries the ink on the surface of the substrate, and then the substrate is sent to the upper side of the second group of printing modules for secondary printing, which effectively improves the ink drying speed, avoids damage to the ink caused by secondary printing, and improves printing efficiency and printing quality.
[0037] See Figures 2 to 4 The ink cartridge 2 is fixedly connected to the side wall of the printing chamber 11, the ink groove 21 is arranged on the right side of the ink cartridge 2, and the ink guide plate 22 is inclined and arranged on the left side of the ink groove 21. The printing roller 210 is rotatably connected to the upper left side of the front and rear inner walls of the ink cartridge 2, and the ink guide roller 211 is rotatably connected to the lower right side of the front and rear inner walls of the ink cartridge 2. The printing roller 210 abuts against the surface of the ink guide roller 211, the scraper 23 is fixedly connected to the left inner wall of the ink cartridge 2, and the ink guide strip 24 is fixedly connected to the lower surface of the scraper 23. The right end of the scraper 23 abuts against the surface of the printing roller 210. A limiting groove 25 is provided on the left side of the upper surface of the ink guide plate 22, and a limiting strip 27 is fixedly connected to the lower surface of the filter box 26. The limiting strip 27 is slidably connected to the limiting groove 25. A filter screen 28 is fixedly connected to the right side of the filter box 26, and a blocking bar 29 is rotatably connected to the front end of the filter box 26.
[0038] Specifically, during printing, the ink guide roller 211 dips the ink inside the ink tank 21 during rotation, and applies the ink to the surface of the printing roller 210. As the printing roller 210 rotates, the scraper 23 scrapes off excess ink and impurities on the surface of the printing roller 210. At this time, the ink guide strip 24 guides the excess ink to the inside of the filter box 26. At this time, the ink inside the filter box 26 is filtered through the filter mesh 28, so that the impurities in the ink remain inside the filter box 26. At this time, the filtered ink is re-collected to the inside of the ink tank 21 through the inclined ink guide plate 22 for recycling and reuse.
[0039] In addition, after a period of use, the blocking bar 29 is pulled to pull the filter box 26 outward, so as to facilitate cleaning of impurities inside the filter box 26 and on the surface of the filter screen 28, thereby improving subsequent filtration speed and ink recovery quality.
[0040] See Figure 2 、 Figure 5 and Figure 6 There are two groups of heating boxes 3, both of which are fixed inside the drying chamber 12. The heat dissipation holes 31 are opened on the upper surface of the heating boxes 3. The inner bottom wall of the heating boxes 3 is fixedly connected with a fixing plate 33. The heating copper wire 34 is fixedly connected to the upper surface of the fixing plate 33. The left and right sides of the ventilation pipe 32 are fixedly connected to the left and right groups of heating boxes 3 respectively, and the exhaust port of the air inlet fan 14 is fixedly connected to the front end of the ventilation pipe 32.
[0041] At the same time, as the printed substrate moves to the right, the ink produced by printing will pass through the upper side of the drying chamber 12. At this time, the heating copper wire 34 is heated by energizing both ends of the heating copper wire 34. The air inlet fan 14 delivers the airflow through the exhaust port to the inside of the ventilation pipe 32. The ventilation pipe 32 delivers the airflow to the inside of the heating boxes 3 on both sides. At this time, the airflow is discharged outward through the heat dissipation holes 31 with hot air to dry the ink on the surface of the upper substrate.
[0042] The working principle of the utility model is as follows: by reducing the distance between the two sets of printing modules, the deviation of the substrate is avoided. At the same time, during the printing process, the drying module dries the ink on the surface of the substrate to avoid damage to the ink during secondary printing and winding, thereby improving the printing quality. In the printing process, the scraped ink is filtered through the filter box 26 and then recycled, effectively improving the ink quality and further improving the printing quality.
[0043] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
