[0024] A second portal frame 5 is provided below the upper connecting plate 4. Positioning cylinders 8 are provided on both sides of the top of the second portal frame 5, and guide cylinders 6 are provided on both sides inside the upper connecting plate 4.

[0025] In use, the positioning cylinder 8 and the guide cylinder 6 are used to position the guide rod 7.

[0026] A guide rod 7 is movably connected inside the guide cylinder 6. The top end of the guide rod 7 extends to the outside of the guide cylinder 6, and the bottom end of the guide rod 7 extends to the outside of the guide cylinder 6 and is fixedly connected to the top of the positioning cylinder 8.

[0027] In use, the guide rod 7 is set to limit the movement range of the second gantry frame 5 in conjunction with the guide cylinder 6;

[0028] The inner walls on both sides of the second portal frame 5 are provided with side connecting plates 9. The top of the side connecting plate 9 is fixed with a top plate 10. Roller seats 12 are slidably connected to the inner walls of the side connecting plates 9 below the top plate 10. A T-shaped rod 15 is provided at the center of the top of the roller seat 12. The top of the T-shaped rod 15 extends through to the top of the top plate 10. The T-shaped rod 15 is movably connected to the top plate 10. A spring 16 is wound on the outer wall of the T-shaped rod 15 between the top plate 10 and the roller seat 12. The two ends of the spring 16 are connected to the top of the roller seat 12 and the bottom of the top plate 10, respectively.

[0034] In this embodiment, the positioning plate 1 is first installed on the coating machine between the sheet take-up and unwrap rollers. The sheet material on the outer wall of the unwrap roller is passed under the tension roller 13 and connected to the take-up roller. Through the elastic action of the spring 16, it works with the T-shaped rod 15 to apply downward elastic pressure to the roller seat 12, causing the roller seat 12 to slide downward on the inner wall of the side connecting plate 9 between the guide rails 11. This allows the tension roller 13 to elastically press down on the sheet material, adaptively adjusting the tension of the sheet. Then, the second gantry frame 5 is driven to rise and fall by the lifting cylinder 17, so that the second gantry... The frame 5, driven by the positioning cylinder 8, moves the guide rod 7 inside the guide cylinder 6 to adjust the distance between the upper connecting plate 4 and the second gantry 5. This allows for the adjustment of the tension roller 13 height to regulate the tension of the sheet material. Finally, the telescopic drive 22 drives the bearing plate 20 to move horizontally, causing the bearing plate 20 to move the rail seat 19 to slide on the outer wall of the limiting rail 18. This allows the bearing plate 20, via the bearing column 2 and the first gantry 3, and other related components, to smoothly move the tension roller 13 laterally, facilitating the correction of the sheet material. This completes the use of the tension adjustment device.
