Description

Technical Field

[0001] The utility model relates to the technical field of ink printing, in particular to a water-based ink printing device for PVC films. Background Technique

[0002] The main component of the PVC film is polyvinyl chloride, which is a widely used synthetic material. In the process of production and manufacturing, an ink printing device is often required to perform ink printing on the surface of the PVC film.

[0003] For example, the Chinese utility model provides an "ink printing machine", publication number: CN216330863U. This application connects two brackets to the base, the printing roller is connected to the two brackets, the auxiliary roller is connected to the two brackets, the ink tank is connected to the two brackets, the motor is connected to the bracket, the rotating shaft is connected to the output end of the motor, the inner rings of the two bearings are fixedly connected to the rotating shaft, the outer rings of the two bearings are fixedly connected to the ink tank, the sealing plate is connected to the rotating shaft, and the coating sponge is connected to the ink tank. The motor drives the rotating shaft to drive the sealing plate to rotate towards the coating sponge, so that the ink flows from the gap generated between the sealing plate and the ink tank to the coating sponge. The larger the rotation angle of the sealing plate, the larger the gap between the sealing plate and the ink tank, and the faster the outflow speed of the ink, solving the problem that the ink printing machine cannot control the outflow speed of the ink from the ink tank, thus affecting the uniformity of ink coating.

[0026] Embodiment Two:

[0027] On the basis of Embodiment One, the utility model is as Figures 1 - 4As shown in the figure, both lower ends of the inner cavity of the fixing frame 11 are fixedly connected with cross plates 23. The top of the cross plate 23 is fixedly connected with a support spring 24. Between the tops of the two support springs 24, there is a fixed frame 25 fixedly connected. The upper end of the fixed frame 25 is movably connected with a support roller 16 through a bearing. Both ends of the bottom of the fixed frame 25 are movably connected with slide bars 26. The bottom of the slide bar 26 is fixedly connected to the top of the cross plate 23. Vertical plates 7 are fixedly connected to the peripheries of the top of the workbench 1. Between the upper ends of the two vertical plates 7, there is a guide roller 8 movably connected through a bearing. The top of the inner cavity of the fixing frame 11 is fixedly connected with a fixing plate 29. The right side of the second motor 30 is fixedly installed on the left side of the fixing plate 29. The upper right side of the fixing frame 11 is fixedly connected with a support plate 12. The right side of the screw rod 17 is movably connected to the lower end of the support plate 12 through a bearing. Between the upper right side of the fixing plate 29 and the upper end of the support plate 12, there is a limiting rod 28 fixedly connected. The upper end of the moving plate 13 is movably connected to the surface of the limiting rod 28. The second gear 22 meshes with the first gear 21. The worm 19 meshes with the worm gear 31. In the middle of the top of the outer surface of the workbench 1, there is a diversion frame 5 fixedly connected. The right end of the back of the diversion frame 5 is fixedly connected with a drain pipe.

[0028] In this technical solution, through the settings of the cross plate 23, the support spring 24, the fixed frame 25 and the support roller 16, the PVC film passing under the printing roller 9 can be supported, effectively ensuring that there can be effective contact between the PVC film and the printing roller 9 during the water-based ink printing process, thus ensuring the printing quality. Through the setting of the slide bar 26, the purpose of guiding the fixed frame 25 is achieved, preventing the fixed frame 25 from tilting due to force. Through the settings of the vertical plate 7 and the guide roller 8, the two ends of the PVC film can be supported and guided. Through the settings of the fixing plate 29, the support plate 12 and the limiting rod 28, while stably supporting the second motor 30 and the screw rod 17, the moving plate 13 can be effectively limited and guided, preventing the moving plate 13 from tilting during the moving process. Through the settings of the diversion frame 5 and the drain pipe, the water flowing down during the cleaning process can be centrally collected and discharged.

[0029] The working principle of the present utility model is as follows: By starting the operation of the transfer pump 3, the water-based ink inside the ink tank 2 can be pumped out, and after being conveyed through the pipeline and the rotary joint 6 to the ink jet pipe 27, it is sprayed evenly onto the surface of the ink roller 10 from the ink jet pipe 27. At the same time, by starting the operation of the first motor 20, the first gear 21 and the printing roller 9 can be driven to rotate. The rotation of the first gear 21 can drive the second gear 22 and the ink roller 10 to rotate, so that the ink roller 10 can evenly coat the water-based ink onto the surface of the printing roller 9 under the action of rotation, and print the water-based ink onto the surface of the PVC film passing below as the printing roller 9 rotates, thereby achieving the effect of printing water-based ink on the PVC film. And when the PVC film printing is completed, by starting the operation of the second motor 30, the worm 19 and the screw 17 can be driven to rotate. While the rotation of the worm 19 can drive the worm gear 31 and the ink jet pipe 27 to rotate, the rotation of the screw 17 can drive the moving plate 13, the brush plate 15 and the cleaning pipe 14 to move to the left until the left sides of the two brush plates 15 can respectively contact the right sides of the printing roller 9 and the ink roller 10, and at the same time, the nozzle of the ink jet pipe 27 can be flipped upward, effectively avoiding the waste caused by the dripping of the residual water-based ink inside the ink jet pipe 27 during the shutdown process. At the same time, under the action of the rotation of the printing roller 9 and the ink roller 10, the brush plate 15 can quickly clean the residual water-based ink on the surface, thereby achieving the effect of initially cleaning the printing roller 9 and the ink roller 10, effectively ensuring the quality of later printing. At the same time, by starting the operation of the water pump 18, the water in the water tank 4 can be pumped out and quickly sprayed onto the surfaces of the printing roller 9 and the ink roller 10 through the cleaning pipe 14, thereby achieving the effect of cleaning the printing roller 9 and the ink roller 10, greatly improving the cleanliness of the surfaces of the printing roller 9 and the ink roller 10, ensuring the quality of later water-based ink printing operations, and facilitating the use by personnel.
