[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A tension adjustment device for a cloth winding machine comprises a mounting frame fixed on the cloth winding machine, the mounting frame corresponds to the cloth winding shaft of the cloth winding machine, the mounting frame is provided with a guide roller cooperating with the cloth winding shaft of the cloth winding machine and a limit block cooperating with the guide roller, the mounting frame is fixed with guide tubes respectively cooperating with two ends of the guide roller, a spring is installed in the guide tube, a connecting rod movable in the guide tube is fixed on the spring, the connecting rod is rotatably connected to the guide roller, the limit block is made of elastic material, the limit block is movably connected to the mounting frame and cooperates with the guide roller.

[0007] It is further configured that an arc plate cooperating with the guide roller is installed on the connecting rod, the guide roller rotates in the arc space of the arc plate, a rubber elastic sheet is provided on the arc plate, and two ends of the rubber elastic sheet are respectively installed on the two ends of the arc plate.

[0008] It is further configured that the limit block includes a sliding surface that contacts the guide roller, and the sliding surface slides on the surface of the guide roller.

[0009] It is further configured that a telescopic rod fixedly connected to the limit block is installed on the mounting frame, and the telescopic rod is detachably connected to the mounting frame through bolts.

[0010] By adopting the above technical scheme, the beneficial effects of the utility model are as follows: in the process of winding up the fabric, the fabric is wound up by the cloth winding shaft on the cloth winding machine after passing through the guide roller on the mounting frame. When the fabric passes through the guide roller, the spring in the guide tube can be retracted to make the connecting rod move in the guide tube, thereby changing the height of the guide roller and timely adjusting the tension of the fabric passing through the surface of the guide roller, so that the fabric always maintains an appropriate tension during the winding process, thereby avoiding excessive or insufficient fabric tension causing unstable winding tension of the fabric during the winding process, uneven tension distribution inside the fabric roll, and wrinkles, thereby improving the quality and use effect of the fabric roll, and adjusting the length of the telescopic rod to make the limit block made of elastic material contact with the surface of the guide roller, and when the height of the guide roller changes, the limit block is deformed to make the fabric always contact with the guide roller, thereby preventing the fabric from deviating and causing wrinkles in the fabric roll during the process of the winder winding up the fabric, thereby further improving the quality of the fabric roll.

[0014] Reference Figure 1 to Figure 2 The embodiments of the utility model are further described.

[0015] A tension adjustment device for a cloth winding machine, comprising a mounting frame 1 fixed on the cloth winding machine, the mounting frame 1 corresponds to the cloth winding shaft of the cloth winding machine, a guide roller 2 matched with the cloth winding shaft of the cloth winding machine and a limit block 3 matched with the guide roller 2 are provided on the mounting frame 1, a guide tube 4 matched with both ends of the guide roller 2 is fixed on the mounting frame 1, a spring 5 is installed in the guide tube 4, a connecting rod 6 movable in the guide tube 4 is fixed on the spring 5, the connecting rod 6 is rotatably connected to the guide roller 2, and a stop block 3 matched with the guide roller 2 is installed on the connecting rod 6 The arc-shaped plate 7 and the guide roller 2 rotate in the arc-shaped space of the arc-shaped plate 7. A rubber elastic sheet 8 is provided on the arc-shaped plate 7. The two ends of the rubber elastic sheet 8 are respectively mounted on the two ends of the arc-shaped plate 7. A telescopic rod 10 fixedly connected to the limit block 3 is mounted on the mounting frame 1. The telescopic rod 10 is detachably connected to the mounting frame 1 by bolts. The limit block 3 is made of elastic material. The limit block 3 is movably connected to the mounting frame 1 and cooperates with the guide roller 2. The limit block 3 includes a sliding surface 9 that contacts the guide roller 2, and the sliding surface 9 slides on the surface of the guide roller 2.

[0016] Working principle: In the process of winding the fabric 11, the fabric 11 passes through the guide roller 2 on the mounting frame 1 and is wound by the cloth winding shaft on the cloth winding machine. When the fabric 11 passes through the guide roller 2, the guide roller 2 is driven to rotate in the arc space in the arc plate 7 and presses the guide roller 2 to make the spring 5 in the guide tube 4 extend and retract to drive the connecting rod 6 to move in the guide tube 4. The two ends of the rubber elastic sheet 8 are respectively installed on the two ends of the arc plate 7 to limit the guide roller 2 in the arc space of the arc plate 7, so as to adjust the height of the guide roller 2 to change the tension of the fabric passing through the guide roller 2, so as to timely adjust the tension of the fabric passing through the surface of the guide roller 2, so that the fabric can be wound in the process of winding. Always maintain the appropriate tension, thereby avoiding excessive or insufficient tension on the fabric surface, which may cause unstable winding tension of the fabric 11 during the winding process, uneven tension distribution inside the fabric roll, and wrinkles, thereby improving the quality and use effect of the fabric roll. The length of the telescopic rod 10 is adjusted to make the limit block 3 made of elastic material contact with the surface of the guide roller 2, and the sliding surface 9 of the limit block 3 slides on the surface of the guide roller 2 to avoid affecting the winding of the fabric 11. When the height of the guide roller 2 changes, the limit block 3 can be deformed to keep the fabric surface in contact with the guide roller 2, thereby preventing the fabric surface from deviating during the process of the winder winding the fabric 11 and causing wrinkles in the fabric roll, thereby further improving the quality of the fabric roll.

[0017] At the same time, when the winder winds fabrics 11 of different widths, it is necessary to replace guide rollers 2 of different lengths to adjust the tension of the fabric surface. The guide roller 2 can be taken out by extending the rubber elastic sheet 8, which is convenient for replacing the guide roller 2 of the corresponding length, and the telescopic rod 10 is disassembled and connected to the mounting frame 1 by bolts, and the position of the telescopic rod 10 on the mounting frame 1 and the length of the telescopic rod 10 are adjusted according to the width of the fabric 11, so that the limit block 3 on the telescopic rod 10 limits the fabrics 11 of different widths passing through the guide roller 2 to prevent deviation, thereby realizing the adjustment of the fabric tension of fabrics 11 of different widths and avoiding deviation of fabrics 11 of different widths when passing through the guide roller 2, thereby improving the use effect and having high practicality.
