[0017] like Figures 1-2As shown, this utility model provides a bonding device for a coating machine, including a bonding frame 1, a pressing roller 9 movably mounted inside the bonding frame 1 at both ends via cylinders 210 and a moving plate 2, a flattening roller 8 in contact with the pressing roller 9, a pressing roller 20 located below the pressing roller 9 and movably mounted inside the bonding frame 1, and a flattening roller 211 in contact with the pressing roller 20. The flattening roller 8 is movably mounted on the moving plate 2 via cylinder 7 and a hinge seat. A limiting plate 29 is movably mounted on the bonding frame 1 via a manual screw assembly 18. A pipe fixing block 20 is movably mounted on the limiting plate 29 via an electric slide rail 21, and the pipe is fixed to the pipe fixing block. On block 20, a pipe is used to inject coating between two layers of optical film. Limiting plate 29 is used to prevent coating from falling into the device. Manual screw assembly 18 is used to adjust the position of limiting plate 29, thereby facilitating maintenance and replacement of internal components of the device. Limiting plate 16 is symmetrically mounted on limiting plate 29 via electric slide rail 17. Limiting plate 16 is used to limit the left and right movement of pipe fixing block 20 to the limit distance, preventing coating from being injected outside the optical film. The two limiting plates 16 and one limiting plate 29 form a U-shaped structure, which can limit the position of coating to the left and right, and prevent coating from falling into the device, thereby ensuring the accuracy of coating position.

[0018] Specifically, both side plates of the bonding frame 1 are provided with limiting holes 11. The moving plate 2 has a connecting rod passing through the limiting holes 11. The second cylinder 10 is mounted on the bonding frame 1, and the end of the second cylinder 10 is mounted on the connecting rod. When the cylinder 10 is opened, the limiting holes 11 can limit the movement of the connecting rod to only within its range. When the connecting rod moves, the moving plate 2 moves accordingly. Subsequently, the moving plate 2 drives the first pressing roller 9 to move, thereby controlling the distance between the first pressing roller 9 and the second pressing roller 10, that is, controlling the thickness of the composite optical film.

[0019] Furthermore, two dial gauges 6 are installed on both sides of the bonding frame 1, with one end of each dial gauge 6 abutting against the moving plate 2, thereby reflecting the movement accuracy in real time and improving the precision of control.

[0020] Furthermore, the top of the movable plate 2 is in contact with the cam 4. The cam 4 is connected by a connecting shaft 5, which is movably mounted on the bonding frame 1 by a motor 3. Thus, when the movable plate 2 moves, the cam 4 can further play a limiting role, and the cam 4 can adjust the limiting position according to the operation requirements.

[0021] Specifically, cylinder 7 and cylinder 22 are symmetrically mounted on the inner wall of the bonding frame 1. Both cylinder 7 and cylinder 22 are equipped with hinge seats. The two ends of the flattening roller 8 are movably mounted on the hinge seats of cylinder 7, and the two ends of the flattening roller 11 are movably mounted on the hinge seats of cylinder 22.

[0022] The control panel is connected to the communication ground of the motor 3, dial indicator 6, cylinder 1 7, cylinder 2 10, electric slide rail 1 17, electric slide rail 2 21 and cylinder 3 22.

[0023] The control panel contains a PLC controller, which is a programmable numerical control system. The PLC acts as the central control system, using a touchscreen to input programs and control the entire machine, achieving full automation of the operation. The control system connects various actuators, allowing them to move along logical trajectories. Programming controls allow these actuators to operate according to the required steps.

[0024] The working principle of this utility model is as follows:

[0025] Optical film 12 passes through transition roller 13 and flattening roller 8 in sequence, and then exits between pressing roller 19 and pressing roller 20. At the same time, optical film 25 passes through transition roller 24 and flattening roller 21 in sequence, and then exits between pressing roller 19 and pressing roller 20. Then, cylinder 210 is activated to adjust the distance between pressing roller 19 and pressing roller 20, and dial indicator 6 is observed simultaneously to ensure its accuracy. Then, motor 3 is activated to adjust the position of cam 4 for limit setting, thereby preventing pressing roller 19 from moving during operation and causing inaccurate work quality. Finally, the position of limit plate 16 is adjusted by electric slide rail 21, and the positions of flattening roller 18 and flattening roller 21 are adjusted by cylinder 17 and cylinder 32. At the same time, manual screw assembly 18 is manually adjusted. At this time, the unwinding roller is activated to unwind optical film 12 and optical film 25, and paint is injected into the pipe between optical film 12 and optical film 25.

[0026] This device precisely controls the thickness of the final laminated product while pressing the optical film. It also has a built-in dial gauge 6, which allows staff to monitor the data in real time and make timely adjustments in case of abnormalities.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
