[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 3 This embodiment of a liquid cooling device for decorative paper processing includes a frame 1, a connecting sleeve 2 rotatably connected inside the frame 1 and extending to its outside, and a cooling roller 3 fixedly installed outside the connecting sleeve 2. A driving mechanism for driving the cooling roller 3 is provided outside the frame 1, and an air-cooling mechanism for air-cooling the decorative paper is provided outside the frame 1 and extending to its inside. An adjustment mechanism for dynamically adjusting the force of the decorative paper is provided on the upper surface of the frame 1 and extending to its inside. The air-cooling mechanism includes a mounting box 4 fixedly installed outside the frame 1 and a diversion pipe 6 provided inside the frame 1. A fan 5 is rotatably installed inside the mounting box 4. An air outlet 7 is fixedly connected to the bottom of the diversion pipe 6. A connecting pipe 8 is fixedly connected between the diversion pipe 6 and the mounting box 4. A synchronization structure is provided outside the fan 5.

[0026] The diversion pipe 6 is fixedly installed on the outside of the fixing frame 13, and there are several air outlets 7. The several air outlets 7 are distributed at equal intervals at the bottom of the diversion pipe 6 and are located outside the guide roller 15.

[0027] Specifically, the drive mechanism includes a motor base 17 fixedly connected to the outside of the frame 1 and a driven gear 20 fixedly installed on the outside of the connecting sleeve 2. A dual-axis motor 18 is fixedly installed inside the motor base 17. A transmission gear 19 is fixedly connected to the output shaft at the right end of the dual-axis motor 18. The transmission gear 19 and the driven gear 20 are meshed with each other.

[0028] It should be noted that the synchronous structure includes a driven wheel 9 fixedly installed outside the fan 5 and a transmission wheel 10 fixedly installed on the output shaft of the left end of the dual-shaft motor 18. The transmission wheel 10 and the driven wheel 9 are externally connected by a belt 11. The dual-shaft motor 18 is started by the controller, and the transmission gear 19 meshes with the driven gear 20 outside the connecting sleeve 2 to drive the cooling roller 3 to rotate, so that the surface of the cooling roller 3 directly contacts the decorative paper to achieve liquid-cooled contact cooling. The synchronous structure drives the fan 5 to rotate synchronously, realizing a single power source to drive liquid cooling and air cooling, reducing the number of motors and energy consumption. The fan 5 draws in ambient air, which is pressurized by the mounting box 4 and then delivered to the distribution pipe 6 through the connecting pipe 8. The distribution pipe 6 distributes the airflow to the air outlets 7 at equal intervals at the bottom to spray out and directionally cool the surface of the decorative paper outside the guide roller 15. At the same time, since the airflow direction is at a certain angle to the running direction of the decorative paper, the heat exchange efficiency is enhanced and the liquid cooling blind zone is eliminated.

[0029] Please see Figure 1 and Figure 2 In this embodiment, the adjustment mechanism includes an electric push rod 12 that is fixedly installed on the upper surface of the frame 1 and extends to its lower surface. A fixed frame 13 is fixedly connected to the output end of the electric push rod 12. An out guide roller 14 and an in guide roller 15 are rotatably installed inside the fixed frame 13.

[0030] The fixed frame 13 is U-shaped, and its outer diameter matches the inner diameter of the frame 1. A guide rod 16 extending to the upper surface of the frame 1 is fixedly connected to the top of the fixed frame 13, and the guide rod 16 is slidably connected inside the frame 1. The electric push rod 12 is extended and retracted by the controller, causing the fixed frame 13 to move up and down along the guide rod 16, thereby adjusting the positions of the guide roller 14 and the feed guide roller 15. This achieves dynamic adjustment of the force on the decorative paper, preventing it from breaking or wrinkling due to tension fluctuations. The addition of anti-slip rubber rings increases friction, ensuring accurate tension adjustment and significantly improving the processing efficiency and product quality of the decorative paper.

[0031] Specifically, both the outward guide roller 14 and the inward guide roller 15 are fixedly connected to the outside of anti-slip rubber rings, and both the outward guide roller 14 and the inward guide roller 15 are located above the cooling roller 3.

[0032] Please see Figure 1In this embodiment, a circulating liquid cooling mechanism is provided on the outside of the frame 1. The circulating liquid cooling mechanism includes a liquid cooling water tank 22 fixedly connected to the outside of the frame 1. A circulating pump 23 is fixedly installed on the back of the liquid cooling water tank 22, and the input end of the circulating pump 23 is connected to the liquid cooling water tank 22. The circulating pump 23 is started by the controller to draw coolant from the liquid cooling water tank 22, and injected into the connecting sleeve 2 through the conveying pipe 24 and the rotating sleeve 21. The coolant flows in the liquid cooling chamber inside the cooling roller 3, exchanges heat with the contact surface of the decorative paper, and then returns to the liquid cooling water tank 22 through the return water pipe, forming a closed loop.

[0033] The output end of the circulating pump 23 is fixedly connected to a delivery pipe 24, which is rotatably connected to one end of the connecting sleeve 2 via a rotating sleeve 21. The liquid cooling water tank 22 is fixedly connected to the other end of the connecting sleeve 2 via a return water pipe.

[0034] The working principle of the above embodiments is as follows:

[0035] In use, the decorative paper enters through the inlet guide roller 15, then passes around the cooling roller 3, and finally exits through the outlet guide roller 14. The controller activates the dual-axis motor 18, which drives the transmission gear 19 to rotate, engaging the driven gear 20 and thus rotating the connecting sleeve 2 and the cooling roller 3, achieving liquid-cooled contact cooling. A synchronous structure drives the fan 5 to rotate synchronously. The fan 5 draws in ambient air, which is pressurized by the mounting box 4 and then transported through the connecting pipe 8 to the distribution pipe 6. The air outlet 7 blows directional air onto the surface of the decorative paper, eliminating liquid-cooling blind spots. The controller activates the circulation pump 23, which draws coolant from the liquid-cooled water tank 22 and injects it into the connecting sleeve 2 through the conveying pipe 24 and rotating sleeve 21. The coolant circulates inside the cooling roller 3, absorbing heat from the decorative paper before returning to the liquid-cooled water tank 22 through the return pipe, forming a closed loop. The controller activates the electric push rod 12 to extend and retract, driving the fixed frame 13 to rise and fall vertically along the guide rod 16, adjusting the distance between the inlet guide roller 15 and the outlet guide roller 14, changing the wrapping angle of the decorative paper, and achieving adaptive tension adjustment.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
