[0021] In this embodiment, a limiting groove is provided on the side wall of the slide groove 5, and the mounting seat 12 is slidingly installed inside the limiting groove. The mounting seat 12 is square in shape, and a pointer 11 is fixedly provided on the top of the mounting seat 12. A scale 10 is provided on the side wall of the top end of the support 1 corresponding to the pointer 11. A handwheel 4 is fixedly provided at one end of the rotating rod 3, and the handwheel 4 is provided on the outside of the support 1. The mounting seat 12 can be limited by the limiting groove to improve the stability of the movement of the mounting seat 12. The pointer 11 is provided to facilitate the adjustment of the pointer 11 to the corresponding scale 10 position as needed, thereby facilitating the adjustment of the active tension roller 7 to a suitable position.

[0022] In this embodiment, the limiting mechanism includes a top plate 9, and a clamping rod 15 is fixedly provided at the bottom of the top plate 9. The clamping rod 15 is slidably installed inside the support 1. The cross-sectional view of the clamping rod 15 is cross-shaped. A spring is mounted on the top of the clamping rod 15, and the top of the spring is fixedly connected to the inner wall of the support 1. The top of the slide plate 6 is equidistantly provided with clamping grooves 16, and the bottom end of the clamping rod 15 is clamped and installed inside the clamping groove 16. The clamping rod 15 is at the lowest end under the elastic force of the spring.

The rotating rod 3 drives the rack 14 through the meshing of the gears 13 at both ends, so that the slide plate 6 slides back and forth inside the slide groove 5. The slides 6 on both sides drive the active tension roller 7 to move in the front-to-back direction through the mounting seat 12. At the same time, the mounting seat 12 drives the pointer 11 and adjusts it to the corresponding scale 10 position, so as to facilitate the adjustment of the position of the active tension roller 7, thereby adjusting the distance between the active tension roller 7 and the fixed tension roller 8, and conveniently adjusting the wrap angle formed by the fabric and the tangent lines of the active tension roller 7 and the fixed tension roller 8. The operation is simple and convenient. The top plate 9 is released, and the top plate 9 and the clamping rod 15 move downward under the action of the spring and are inserted into the corresponding clamping groove 16. The active tension roller 7 after adjustment is conveniently fixed through the limiting mechanism such as the clamping rod 15, thereby improving the stability of the active tension roller 7, and the practicability is high.
