[0030] Among them, the electric adjustment component 3 includes a U-shaped electric slide mounting seat 34 installed on the unwinding mechanism on one side of the manual slide mounting seat 21, a second screw rod 35 is rotatably connected between the middle of the upper and lower ends of the electric slide mounting seat 34, an electric slide 36 is threadedly connected to the second screw rod 35, a guide rail 38 is arranged on the inner side wall of the electric slide mounting seat 34 along the length direction, a slider 37 adapted to the guide rail 38 is fixedly connected to one side of the electric slide 36, the slider 37 is slidably connected to the guide rail 38, a servo motor 32 for driving the second screw rod 35 to rotate is arranged under the manual slide mounting seat 21, and one end of the second seat bearing 13 is fixedly connected to the electric slide 36.

[0031] A motor mounting frame 31 is disposed below the electric slide mounting seat 34 , and the servo motor 32 is mounted on the motor mounting frame 31 .

[0036] The working principle of the utility model is as follows: when the substrate passes through the tension sensor, the tension sensor detects the tension on both sides of the substrate, and the tension sensor transmits the signal to the controller. The controller determines the tension at both ends of the tension adjustment roller and compares the tension on both sides. When the tension on the electric adjustment component side is greater than the tension on the manual adjustment component side, it means that the substrate on the electric adjustment component side is tighter, and the electric slide on the electric adjustment component side needs to be adjusted upward. Otherwise, it means that the substrate on the manual adjustment component side is tighter, and the electric slide on the electric adjustment component side needs to be adjusted downward. The controller controls the servo motor of the electric adjustment component to rotate, drive the second screw rod to rotate, and drive the electric slide to move up and down. The manual adjustment component side can rotate the first screw rod by the manual adjustment knob to drive the manual slide to move up and down. A limit assembly is provided at the electric adjustment component. When the electric slide moves, the induction sheet connected to the electric slide will also move accordingly. When the movement exceeds the upper limit sensor or the lower limit sensor, the limit sensor will transmit a signal to the controller, and the controller will stop the servo motor accordingly to avoid excessive movement of the electric slide and excessive tension adjustment.
