Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model. Embodiment 1

[0026] Please refer to Figures 1-9, this embodiment provides a special ink printing and drying integrated machine, including a frame 1. At the upper end of the frame 1, a drying box 2 is provided. At the bottom of the drying box 2, a film flow port 3 is provided. Among them, the drying box 2 has been fully disclosed and described in the Chinese utility model patent with the application number CN202420263087.0 and is an existing mature medium, and its internal structure will not be elaborated. At the lower end of the frame 1, a printing roller 5 corresponding to the film flow port 3 is provided. Above the printing roller 5, a film pressing roller 4 is arranged to be liftable. It should be noted that, as Figure 3 shown, the lifting of the film pressing roller 4 is driven by a hydraulic cylinder 9. On one side of the printing roller 5, an ink scraping device 8 is provided. The ink scraping device 8 includes a scraper 14 for scraping off the excess ink on the printing roller 5. Below the printing roller 5, an ink cartridge 6 is provided. When the printing roller 5 rotates, its lower surface continuously dips into the water-based ink in the ink cartridge 6. It should be noted that the above printing roller 5, film pressing roller 4, scraper 14, and ink cartridge 6 are all conventional general structures used in printing and drying machines. The printing roller 5 can be rotated by motors on both sides, which are all conventional technologies and will not be elaborated in this application. To solve the problem that the film is prone to deviation on traditional integrated machines, a film deviation rectifying device 7 is provided on the frame 1 to prevent the film from deviating during the running process.

[0027] Among them, as Figures 4-6 shown, the film deviation rectifying device includes a fixing plate 12 fixedly arranged on the frame 1. At the upper end of the fixing plate 12, a movable plate 10 is rotatably connected. On the movable plate 10, a deviation rectifying roller 11 is rotatably arranged. The cross-sectional diameter of the deviation rectifying roller 11 gradually increases from the middle to both ends. On one side of the movable plate 10, a driving component is provided for driving the movable plate 10 to swing reciprocally. Among them, preferably, as a conventional design familiar to those skilled in the art, in this embodiment, the driving component includes a cylinder 19 arranged on the frame 1. The output end of the cylinder 19 is connected with a connecting rod 18. One end of the roller shaft of the deviation rectifying roller 11 is movably connected with the connecting rod 18 through a spherical bearing 17. At the same time, combined with Figure 9 shown, in practical applications, in order to automatically judge whether the film is deviated during movement, as a conventional design, a pair of photoelectric sensors 24 can be designed above the deviation rectifying roller 11. When the film 23 deviates, the deviated film 23 is sensed by the photoelectric sensors 24. The photoelectric sensors 24 send signals to an external controller, and the controller controls the cylinder 19 to push the movable plate 10 to move reciprocally and quickly, so that the film 23 returns to the center of the deviation rectifying roller 11 to complete the deviation rectification. Among them, the photoelectric sensors 24 and the controller are both conventional general structures and will not be elaborated. At the same time, in this application, two deviation rectifying rollers 11 are provided. In practical applications, it can be designed according to actual needs.

[0028] Since the conventional scraper 14 is fixed and installed by bolts, it is not convenient to load and unload. In order to quickly replace the scraper 14, combined with Figure 2 、Figure 4 , Figure 7 and Figure 8 As shown, in the present application, the ink scraping device 8 includes a fixed pressing plate 15 disposed on the frame 1. Among them, the fixed pressing plate 15 is an existing mature technology. On a traditional all-in-one machine, the scraper 14 is directly fixed to the fixed pressing plate 15 by bolts. The fixed pressing plate 15 can be adjusted back and forth, up and down on the frame 1. This is a conventional and general design of an existing printing and drying all-in-one machine, which will not be elaborated in the present application; in the present application, an installation groove 20 is formed on the fixed pressing plate 15, and a rotatable cam ejector rod 21 is disposed in the installation groove 20. An operating rod 16 is disposed behind the cam ejector rod 21. The operating rod 16 penetrates through the installation groove 20 and is located outside the fixed pressing plate 15. A movable pressing plate 13 is disposed on the fixed pressing plate 15. The rear side of the movable pressing plate 13 is located above the cam ejector rod 21. The rear side of the movable pressing plate 13 is movably connected to the fixed pressing plate 15 through a connecting pin 22. A scraper 14 is clamped between the fixed pressing plate 15 and the movable pressing plate 13. As Figure 8 shown, when the operating rod 16 is in a horizontal state, at this time, the protrusion of the cam ejector rod 21 abuts against the rear side of the movable pressing plate 13, so that the front side of the movable pressing plate 13 presses the scraper 14 tightly; when the scraper 14 needs to be disassembled, the operating rod 16 is pulled upward, the cam ejector rod 21 rotates, and its protrusion leaves the movable pressing plate 13, making the front side of the movable pressing plate 13 loose, and the scraper 14 can be easily pulled out. As common sense, as Figure 7 shown, a notch for the movement of the operating rod 16 should be designed on the fixed pressing plate 15, which will not be elaborated in the present application.

[0029] In addition, in order to facilitate the monitoring of the ink volume in the ink cartridge 6, an ink volume monitoring component should be provided on the ink cartridge 6. Specifically, the ink volume monitoring component can be a liquid level sensor. A liquid level sensor for monitoring the liquid level height in the ink cartridge 6 can be disposed in the ink cartridge 6. The liquid level sensor can be obtained by customized purchase, which will not be elaborated in the present application; at the same time, considering that the ink has a certain viscosity, although the liquid level sensor can complete the ink volume monitoring during use, the effect is not good; therefore, the ink volume monitoring component can also be a weighing sensor, which can be achieved by disposing a weighing sensor at the bottom of the ink cartridge 6. Its structure and installation are conventional technologies familiar to those skilled in the art, which will not be elaborated in the present application.

[0030] In practical applications, a corresponding film guide roller should also be provided outside the all-in-one machine. This is common sense and will not be elaborated; the film introduced into the all-in-one machine first passes through the deviation rectifying roller 11, then bypasses the film pressing roller 4 and enters the drying box 2 through the film flow port 3. After drying, it comes out from the film flow port 3, and then the film is guided away by the corresponding guide roller. The flow mode of the film should be a conventional setting, which will not be elaborated in the present application.

[0031] It should be noted that the above embodiments only specifically and clearly describe the technical solutions and technical features of the present application. For those skilled in the art, the solutions or features that belong to the prior art or common general knowledge are not described in detail in the above embodiments.

[0032] In addition, the technical solutions of the present application are not limited to the above embodiments. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation manners that can be understood by those skilled in the art.
