DETAILED DESCRIPTION
[0015] The embodiment of the utility model is further described below in combination with the drawings.
[0016] As Figs. 1-3 shown, a double-sided printing device includes a mounting frame 1, the mounting frame 1 is provided with a first mounting plate 3 and a second mounting plate 4, the upper end surface of the first mounting plate 3 and the lower end surface of the second mounting plate 4 are respectively provided with a first air cylinder 5, the output ends of the two first air cylinders 5 are respectively provided with a printing plate 6, the two printing plates 6 are located between the first mounting plate 3 and the second mounting plate 4, the mounting frame 1 is slidably connected with two groups of ink application assemblies, the two groups of ink application assemblies apply ink to the two printing plates 6 respectively, the ink application assembly includes a mounting groove 7, the inside of the mounting groove 7 is provided with a rotatable roller 8, the inner side of the mounting groove 7 is provided with an ink pipe 9, the side of the ink pipe 9 is uniformly provided with an ink jet nozzle 10, one end of the ink pipe 9 is provided with an ink inlet port 11, one side of the mounting groove 7 is provided with two fixed rods 12, the fixed rods 12 penetrate through the mounting frame 1 and are slidably connected with the mounting frame 1, the fixed rods 12 in the two groups of ink application assemblies are connected through a four-corner plate 13, the mounting frame 1 is provided with a second air cylinder 14, the output end of the second air cylinder 14 is fixedly connected with the four-corner plate 13.
[0017] The outer surface of the printing plate 6 has a protruding part, the ink on the roller 8 can only be coated on the protruding part of the printing plate 6, and the printing plate 6 realizes printing on the packaging material 2 through the ink on the protruding part.
[0018] The outer surface of the roller 8 is made of rubber material, and the outer surface of the roller 8 has micropores. The external ink storage tank is transported into the ink pipe 9 through the pump body, the pipeline and the ink inlet port 11, and then sprayed on the outer surface of the roller 8 through the ink jet nozzle 10 on the ink pipe 9. The spraying range of the ink jet nozzle 10 is only controlled on the outer surface of the roller 8. The micropores on the outer surface of the roller 8 are convenient for storing ink. When it is needed to coat the ink on the printing plate 6, the printing plate 6 needs to be reset through the first air cylinder 5 first, and then the four corner plates 13 are moved through the second air cylinder 14, and then the four fixed rods 12 and the installation slot 7 and the roller 8 are moved through the four corner plates 13. When the roller 8 moves, the roller 8 will be extruded by the printing plate 6, so that the outer surface of the roller 8 is compressed to a certain extent, so as to better coat the ink on the printing plate 6. In the process of moving the roller 8 on the printing plate 6, the roller 8 will rotate through the friction between the roller 8 and the printing plate 6, and in the process, the ink jet nozzle 10 will spray an appropriate amount of ink on the outer surface of the roller 8, so as to ensure that the outer surface of the roller 8 can transfer sufficient ink to the printing plate 6, and the spraying time of the ink jet nozzle 10 is controlled to avoid the ink from dripping from the roller 8.
[0019] When printing on both sides of the packaging material 2, the packaging material 2 first passes through the middle of the two printing plates 6 from top to bottom, and then the two printing plates 6 are coated with ink through the two rollers 8 respectively. Then the roller 8 is moved to one side of the printing plate 6, and then the two first air cylinders 5 are controlled to start at the same time, and the two first air cylinders 5 respectively push the two printing plates 6 to move towards the packaging material 2. The moving speed of the two printing plates 6 is the same, and the double-sided printing of the packaging material 2 is realized through the extrusion of the two printing plates 6. After completing the double-sided printing of the packaging material 2, the two printing plates 6 are reset through the two first air cylinders 5, and then the packaging material 2 is moved to the next printing position. When the two printing plates 6 are reset, the roller 8 continues to ink the printing plate 6, so as to continue the double-sided printing of the packaging material 2.
[0020] Further, the printing plate 6 is provided with a guide rod 15 on one side, and the first mounting plate 3 and the second mounting plate 4 are provided with through holes slidably connected with the guide rod 15, so as to improve the stability of the two printing plates 6 when moving up and down.
[0021] Further, the end of the guide rod 15 away from the printing plate 6 is provided with a baffle 16, so as to limit the guide rod 15 on the first mounting plate 3 and the second mounting plate 4.
[0022] Further, the guide rod 15 is sleeved with a spring 17, so as to avoid the vibration phenomenon of printing caused by the loose cooperation between the guide rod 15 and the first mounting plate 3 and the second mounting plate 4 when the printing plate 6 moves up and down, which is beneficial to improve the printing quality.
[0023] Further, the bottom of the mounting frame 1 is provided with a Foma wheel 18, facilitating the movement and fixation of the printing device.
