[0003] When a fabric winding machine winds up the fabric, the rotation of the winding rollers and the long-distance transmission of the fabric during winding can easily cause the fabric to deviate or stretch abnormally. Therefore, it is necessary to install an anti-deviation device on the fabric winding machine to correct fabric deviation. To this end, we propose a tension-adaptive anti-deviation device for fabric winding machines. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example Reference Figures 1-5 A tension-adaptive anti-deviation device for a fabric winding machine includes two parallel base plates 1 connected by a connecting plate 2. In actual use, through holes for mounting bolts are provided on the base plates 1 to fix the base plates 1 to the fabric winding machine (e.g., [missing information]). Figure 5 (At the position indicated by the middle arrow A).

[0020] A smoothing mechanism for smoothing the fabric is provided above the space between the two base plates 1, such as... Figure 1 and Figure 2 As shown, the smoothing mechanism includes a crossbeam 3. The end of the crossbeam 3 is fixed to the base plate 1 via a support frame 4. A first U-shaped frame 5 with an opening facing downward is provided below the crossbeam 3. A screw 8 is rotatably installed at the top center of the first U-shaped frame 5. The screw 8 passes through the crossbeam 3 and is threadedly connected to the crossbeam 3. The height of the first U-shaped frame 5 can be adjusted by rotating the screw 8.

[0021] Furthermore, in order to ensure that the rotation of the screw 8 can stably drive the first U-shaped frame 5 to lift and lower, a first guide shaft 11 is vertically installed at both ends of the top of the first U-shaped frame 5, and the top of the first guide shaft 11 slides through the crossbeam 3.

[0022] A lead screw 6 is provided inside the first U-shaped frame 5. The end of the lead screw 6 is rotatably connected to the inner wall of the first U-shaped frame 5, and a drive motor 26 is installed at one end of the lead screw 6. The drive motor 26 is fixed on the outer wall of the first U-shaped frame 5. A movable seat 7 is connected to the lead screw 6 by a threaded nut. A second U-shaped frame 9 with an opening facing downward is installed at the bottom of the movable seat 7, and a guide roller 10 is rotatably installed inside the second U-shaped frame 9. Under the forward and reverse operation of the drive motor 26, the lead screw 6 will be driven to rotate, thereby causing the movable seat 7 to move back and forth along the axis of the lead screw 6. This can drive the guide roller 10 to perform reciprocating linear motion, which can push the fabric in contact with the guide roller 10, allowing the fabric to be fully unfolded to both sides, ensuring the winding effect of the fabric. In actual use, the lead screw 6 can be a reciprocating lead screw, so that the drive motor 26 can realize the reciprocating motion of the guide roller 10 without forward and reverse power supply.

[0023] Furthermore, the top of the movable seat 7 is fitted with the inner wall of the first U-shaped frame 5 with a clearance to limit and guide the movement of the movable seat 7, preventing the movable seat 7 from deflecting due to the rotation of the screw 6, which would cause the guide roller 10 to detach from the fabric.

[0024] A tensioning mechanism for adjusting the tension of the fabric is provided on the side of the pushing mechanism. The tensioning mechanism is mounted on the base plate 1, as follows: Figure 1 As shown, the tensioning mechanism includes two parallel tensioning rollers 12. The ends of the tensioning rollers 12 are rotatably mounted on a support plate 13, and the bottom of the support plate 13 is rotatably mounted in a first U-shaped seat 14. The first U-shaped seat 14 is fixed on the base plate 1. An inclined first pushing member 15 is provided on the side of the support plate 13. The ends of the first pushing member 15 are rotatably mounted on a second U-shaped seat 16. One second U-shaped seat 16 is fixed on the base plate 1, and the other second U-shaped seat 16 is fixed on the side of the support plate 13. In actual use, the first pushing member 15 is one of an electric push rod, a cylinder, or a hydraulic cylinder, which allows the support plate 13 to deflect within the first U-shaped seat 14, thereby driving the two parallel tensioning rollers 12 to deflect, thus pulling the fabric passing between the two tensioning rollers 12 and realizing the tensioning operation of the fabric during conveying.

[0025] A correction mechanism for correcting fabric misalignment is provided on the side of the tensioning mechanism away from the smoothing mechanism, and the correction mechanism is mounted on the base plate 1, such as... Figure 3 and Figure 4As shown, the correction mechanism includes a third U-shaped frame 17 with its opening facing upwards. A correction roller 18 is rotatably mounted inside the third U-shaped frame 17. An arc-shaped groove 19 is formed along the outer wall of the correction roller 18. A third U-shaped seat 20 is mounted at the bottom of the third U-shaped frame 17. A support rod 21 is rotatably mounted inside the third U-shaped seat 20. A fixing plate 22 is mounted at the bottom of the support rod 21. A second pushing member 23 is mounted at the bottom of the fixing plate 22. The bottom of the second pushing member 23 is fixed to the connecting plate 2. A third pushing member 24 is provided on the side of the support rod 21 at an incline. The end of the third pushing member 24 is rotatably mounted on a fourth U-shaped seat 25. One of the fourth U-shaped seats 25 is fixed to the support rod 21. On rod 21, another fourth U-shaped seat 25 is fixed on the third U-shaped frame 17. In actual use, the second pusher 23 and the third pusher 24 are both electric push rods, cylinders, and hydraulic cylinders. Under the operation of the second pusher 23, the height of the correction roller 18 is adjustable, so as to match the adjustment of the fabric by the tension roller 12 and make the top surface of the correction roller 18 fit against the fabric. When the fabric deviates, the third pusher 24 can act on the third U-shaped frame 17 to drive the correction roller 18 to deflect, so that the raised end of the correction roller 18 acts on the side of the fabric and is pushed down on the second pusher 23 to make the fabric deviate to the initial position to prevent the fabric from running off track when it is rolled up.

[0026] It should be noted that, in order to accurately identify the deviation of the fabric during transmission, a deviation correction sensor is installed on the fabric winding machine. The deviation correction sensor is connected to the controller of the fabric winding machine through wires, and the drive motor 26, the first pusher 15, the second pusher 23, and the third pusher 24 are all connected to the controller through wires. The deviation correction operation is performed based on the measurement of the deviation correction sensor. In addition, a tension sensor can be installed on the outer wall of the guide roller 10 to monitor the tension of the fabric during winding, so that the tension can be adjusted appropriately by the first pusher 15 in a timely manner.

[0027] It should be further explained that a sleeve 29 is provided parallel to the side of the second pusher 23. The top of the sleeve 29 is fixed to the fixing plate 22, and a second guide shaft 30 is built into the bottom of the sleeve 29. The bottom of the second guide shaft 30 is fixed to the connecting plate 2 to guide the lifting and lowering of the correction roller 18 and ensure the stability of the lifting and lowering of the correction roller 18.

[0028] Specifically, to ensure that the fabric falls stably onto the take-up roller of the fabric winding machine after being fed from the correction roller 18, two parallel support rollers 27 are provided on the side of the correction mechanism away from the tensioning mechanism. The ends of the support rollers 27 are rotatably mounted on the support base 28, and the support base 28 is fixed on the base plate 1. In use, after the fabric passes over the correction roller 18, the fabric passes over the support rollers 27 located above and is arranged in an S-shape around the two support rollers 27, and finally is fixed on the take-up roller of the fabric winding machine.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
