[0019] Example 2: Please see Figure 1 Based on Embodiment 1, the frame 1 on the left side of the adjustment mechanism is also equipped with a sensor 2, an electric push rod 4, a correction roller 3, a drive mechanism 5, and a guide mechanism 6.

[0020] When using this utility model, the substrate led out from the drying box passes under the right-side correction roller 3, goes around the right-side fixed roller 7-1, under the adjusting roller 7-2, and above the left-side fixed roller 7-1, and then passes under the left-side correction roller 3. When sensor 2 on the right detects a shift in the edge of the substrate, it activates drive motor 5-5. The rotation of drive motor 5-5 causes gear 1 5-6 to rotate, which in turn drives gear 2 5-7 to rotate. This causes moving frame 5-4 to move on rack 5-8.

The correction roller 3 corrects the substrate, and under the action of spring 7-6, the substrate's tension is kept within a suitable range. When the substrate is too loose, pressure rod 7-9 contacts pressure sensor 7-8, activating cylinder 7-7 and causing adjusting roller 7-2 to press down, allowing the substrate's tension to be better adjusted. After adjustment, the substrate passes through sensor 2 on the left and correction roller 3, allowing for secondary detection and adjustment to avoid incomplete adjustment in one attempt.

[0021] Compared with the prior art, the beneficial effects of this utility model are: 1. By using dual sensors 2 and dual correction rollers 3, secondary detection and adjustment of substrate offset are achieved, improving correction accuracy and reliability; 2. The gear transmission structure (gear 5-6, gear 5-7 and rack 5-8) and diameter difference design are adopted to accelerate the response speed of the correction roller 3 and improve the dynamic response efficiency. 3. The tension of the substrate is automatically adjusted by the linkage mechanism of spring 7-6 and cylinder 7-7 (pressure rod 7-9, pressure sensor 7-8, adjusting roller 7-2) to avoid the substrate being too loose or too tight, which would affect the correction effect. 4. It integrates the correction and tensioning functions into one unit, optimizes the structural space, and is suitable for high-speed and high-precision coating production scenarios.
