[0024] like Figure 2 As shown, the unwinding mechanism 1 includes a frame 7, on which a first roller 4 and a second roller 5 are mounted. Two guide side plates 9 are symmetrically fixed to the top of the frame 7, and multiple rollers 6 are rotatably engaged between the two guide side plates 9. The multiple rollers 6 cooperate with each other to guide the fabric. A motor 11 is provided on the side of the first roller 4, and the output shaft of the motor 11 is fixedly connected to the first roller 4 to provide the driving force for the rotation of the first roller 4.

[0025] like Figure 2 As shown, the bottom of the frame 7 is also equipped with pulleys 8 for moving the unwinding mechanism 1 or the winding mechanism 3. Positioning plates 10 are fixed at both ends of the bottom of the frame 7, and positioning bolts 24 are provided on the bottom surface of the positioning plates 10 for fixing the frame 7 to the ground.

[0026] like Figure 3 As shown, the cutting mechanism 2 includes a bracket 17, with transport side plates 18 fixed on both sides of the top of the bracket 17, and two support rods 16 fixed between the transport side plates 18. A front centering inclined plate 12 and a rear centering inclined plate 19 are distributed at both ends of the transport side plates 18. The front centering inclined plate 12 is close to the unwinding mechanism 1, and the rear centering inclined plate 19 is close to the winding mechanism 3.

[0027] like Figures 3-5As shown, a plurality of transverse adjusting rollers 21 and a first lead screw 14 are rotatably fitted on the front centering inclined plate 12. The threads on both sides of the first lead screw 14 are opposite, with the center plate 22 fitting on each side. A first adjusting turntable 26 is fixedly connected to one end of the first lead screw 14 for rotating the first lead screw 14, thereby bringing the two centering plates 22 closer together or further apart. The transverse adjusting rollers 21 are rotatably fitted with continuous transverse sliding shafts 23. The transverse sliding shafts 23 include a base 25, on which four sets of roller shafts 27 that can rotate along the length direction of the transverse adjusting rollers 21 are provided, which can ensure that the curtain fabric moves more smoothly in the transverse direction after being placed on the front centering inclined plate 12. A sliding cutter 20 is provided at the end of the front centering inclined plate 12. Based on the required width of the curtain fabric, the width to be cut for the initial curtain fabric is calculated, and the position of the sliding cutter 20 on the front centering inclined plate 12 is adjusted to cut the curtain fabric.

[0028] like Figure 3 As shown in Figure 6, a plurality of longitudinal rotating rollers 29 and a second lead screw 28 are rotatably fitted on the rear centering inclined plate 19.

The backing cloth, guided by roller 6, is rewound onto the second roller 5 of the unwinding mechanism 1. The separated fabric passes sequentially through the front centering inclined plate 12, support rod 16, and rear centering inclined plate 19 before being recombined with the backing cloth and wound onto the first roller 4 of the winding mechanism 3.

[0030] As the curtain passes the front centering ramp 12, the first adjusting turntable 26 is rotated to bring the two centering plates 22 closer together, thereby positioning the curtain in the middle of the front centering ramp 12. Then, the position of the sliding cutter 20 is adjusted so that the blade is fixed facing the back of the curtain, allowing the sliding cutter 20 to continuously cut the curtain. As the curtain passes the rear centering ramp 19, the second adjusting turntable 30 is rotated to bring the two sliders 15 closer together, thereby clamping the curtain in the middle of the rear centering ramp 19 with the centering rod 13.
