[0051] In this embodiment, in order to solve the problem in the related art that the strip cannot enter the tension adjusting device because the position of the strip is not fixed when it enters the tension adjusting device, a strip tension adjusting device is designed. Among them, the frame 1 serves as the supporting structure of the entire device. The sliding block 2 is vertically slidably arranged on the frame 1.

In this way, the rotating plate 301 can realize the angle adjustment of the guiding plate 3, and the sliding plate 302 can further extend the length of the guiding plate 3, so that it can better adapt to different feeding positions and strip lengths.

[0055] The advantages are as follows. The combined design of the rotating plate 301 and the sliding plate 302 enables the guiding plate 3 to adjust its position and length more flexibly, improving the adaptability to different strip steel specifications and feeding conditions. It can more accurately guide the strip steel into the device, reduce the offset and distortion of the strip steel, and ensure the stability of the strip steel during the tension adjustment process. It enhances the versatility of the device, can meet more different production requirements, and improves production efficiency. It helps to reduce the friction and damage of the strip steel during transmission, improving the surface quality and service life of the strip steel.

When the third telescopic member 16 extends, it pushes the first swing plate 15 to rotate around the swing point, causing the first pressure roller 6 to approach the first S-shaped pressure roller 7, thereby adjusting the size of the first pressing space 8 to adapt to strip steel of different thicknesses.

[0061] The advantage is that through the control of the third telescopic member 16, the distance of the first pressing space 8 between the first pressure roller 6 and the first S-shaped pressure roller 7 can be precisely adjusted, thereby realizing the adjustment of the pressing force on strip steel of different thicknesses, ensuring the stability of the strip steel during transmission and the control of the tension force. It can improve the pressing effect of the strip steel, reduce the sliding and slack of the strip steel during transmission, and improve the production efficiency and product quality.
