[0016] Please refer to Figures 1-3, the present utility model provides a technical solution for a fabric unwinding device: A fabric unwinding device includes a roller 1, a rotating shaft 2 is fixedly connected to the inner wall of the roller 1, a pressing block 3 is arranged above the roller 1, the pressing block 3 can be detachably connected to the roller 1 through a pressing groove 12, the pressing groove 12 is opened above the outer wall of the roller 1, sealing blocks 4 are arranged at both ends of the pressing block 3, the sealing blocks 4 are connected to the pressing block 3 through bolts 5, the bolts 5 penetrate through the sealing blocks 4 and are threadedly connected to the pressing block 3, the bottom end of the sealing block 4 is fixedly connected to a telescopic rod 6, and the other end of the telescopic rod 6 is fixedly connected to the contact surface of the roller 1. A fabric 7 is arranged between the pressing block 3 and the roller 1. Baffles 8 are arranged on both sides of the pressing block 3, and the baffles 8 are connected to the pressing block 3 through a connecting component 9. The connecting component 9 includes a T-shaped groove 901, a vertical rod 902, a resisting plate 903, a rubber pad 904, an arc-shaped plate 905, a ball 906, a first slider 907, a first chute 908, a compression spring 909, a second chute 910 and a second slider 911. The T-shaped groove 901 is opened above the surface of the pressing block 3. Two vertical rods 902 are arranged in sequence from front to back inside the T-shaped groove 901. The bottom end of the vertical rod 902 is fixedly connected to the resisting plate 903. A rubber pad 904 is fixedly connected to the lower surface of the resisting plate 903. The rubber pad 904 is made of rubber material and has a certain flexibility. The rubber pad 904 abuts against the contact surface of the pressing block 3. An arc-shaped plate 905 is sleeved above the outer wall of the vertical rod 902. A plurality of balls 906 are slidably clamped on both sides of the upper surface of the arc-shaped plate 905. The balls 906 can roll but cannot be separated from the arc-shaped plate 905. The balls 906 are in contact with the contact surface of the pressing block 3. Both ends of the arc-shaped plate 905 are fixedly connected to first sliders 907. The first sliders 907 are slidably clamped to the pressing block 3 through the first chute 908. The first sliders 907 can slide in the front-back direction inside the first chute 908 but cannot move up, down, left or right, which can improve the stability of the arc-shaped plate 905 during sliding inside the T-shaped groove 901. A compression spring 909 is sleeved below the outer wall of the vertical rod 902. The coefficient of the compression spring 909 is 2 - 5 N / cm. The upper and lower ends of the compression spring 909 are respectively fixedly connected to the contact surfaces of the arc-shaped plate 905 and the resisting plate 903. Second chutes 910 are vertically opened on both the front and back sides of the outer wall of the vertical rod 902. Second sliders 911 are slidably clamped inside the second chutes 910. The second sliders 911 are fixedly connected to the inner wall of the arc-shaped plate 905. The second chutes 910 can play a role in sliding limit for the second sliders 911. The second sliders 911 can slide up and down inside the second chutes 910 but cannot move left, right, front or back. A scale 10 is arranged on the upper surface of the pressing block 3. The scale 10 can facilitate the judgment of the distance between the two baffles 8, so as to quickly adapt to the use of fabrics 7 with different widths. The two side surfaces of the baffle 8 are processed with chamfers 11. The chamfers 11 can increase the friction force on both side surfaces of the baffle 8, which is convenient for the operator to apply force to the baffle 8.

[0017] During the use of the fabric unwinding device, first, the roller 1 is installed at a suitable position through the transmission shaft 2. Then, a part of the fabric 7 wound around the outside of the roller 1 is placed between the pressing block 3 and the roller 1. Next, the pressing block 3 is snapped into the inside of the pressing groove 12, and the connection between the fabric 7 and the roller 1 can be quickly established. By driving the rotating shaft 2 and the roller 1 to rotate, the fabric 7 can be wound. Before the winding operation, the operator can apply an upward force to pull the baffle 8, and the compression spring 909 will be compressed. The rubber pad 904 on the lower surface of the abutting plate 903 will be separated from the pressing block 3. While maintaining the upward force on the baffle 8, a lateral force is applied to it, and the position of the baffle 8 above the pressing block 3 can be adjusted to facilitate the limiting use of fabrics 7 with different widths. After determining the position of the baffle 8, the force applied to it is released, and the compression spring 909 rebounds. The rubber pad 904 on the lower surface of the abutting plate 903 will contact and press tightly against the pressing block 3, which can greatly enhance the stability between the baffle 8 and the pressing block 3, making the baffle 8 not prone to deviation when not affected by external forces, and facilitating the subsequent high-quality winding and unwinding operations of the fabric 7.
