The following describes an embodiment of the present invention based on its overall structure.

[0028] See also Figures 1 to 8In an embodiment of the present invention, a tension control device for a winding machine includes a base 1, a first side plate 2 and a second side plate 3 are symmetrically fixedly connected on both sides of the base 1, a first fixed shaft 4 is fixedly connected between the two first side plates 2, and a second fixed shaft 5 is fixedly connected between the two second side plates 3. The outer wall of the first fixed shaft 4 is rotatably connected to a first guide wheel 6, and the outer wall of the second fixed shaft 5 is rotatably connected to a second guide wheel 7. The tension of the yarn is adjusted by an adjusting mechanism 8.

[0029] The adjusting mechanism 8 includes a movable groove 801, which is opened at the top of the base 1. The top of the base 1 is located on both sides of the movable groove 801 and is fixedly connected to a limit frame 802. The inner wall of the limit frame 802 is slidably connected to an adjusting frame 803. The top of the adjusting frame 803 is rotatably connected to a tension wheel 804. The yarn passes through the bottom end of the tension wheel 804. The inner wall of the movable groove 801 is symmetrically slidably connected to a movable plate 806. The top of the movable plate 806 is rotatably connected to a connecting rod 805. The top of the connecting rod 805 is rotatably connected to the adjusting frame 803.

[0030] The adjusting mechanism 8 also includes a threaded rod 807, which is rotatably connected to the interior of the base 1 and passes through the movable plate 806. One end of the threaded rod 807 is fixedly connected to the first spur gear 808, and the first spur gear 808 extends out of the top of the base 1. The interior of the base 1 is located at the bottom end of the first spur gear 808 and is slidably connected with a positioning block 809. A first spring 810 is connected between the bottom end of the positioning block 809 and the base 1. The interior of the base 1 is located at one end of the positioning block 809 and is slidably connected with a clamping block 811. A second spring 812 is connected between the clamping block 811 and the base 1. The interior of the base 1 is located above the clamping block 811 and is slidably connected with a lower pressure rod 813. The lower pressure rod 813 extends to the top of the base 1, and the first spur gear 808 is driven to rotate by the driving mechanism 9.

[0031] In this embodiment, the yarn passes through the bottom end of the first guide wheel 6 and then passes through the top end of the second guide wheel 7. During this process, the yarn passes through the bottom end of the tension wheel 804. When the tension of the yarn is adjusted, the first spur gear 808 is rotated, and the rotation of the first spur gear 808 drives the threaded rod 807 to rotate, and the rotation of the threaded rod 807 drives the two movable plates 806 to move in opposite directions. The displacement of the movable plate 806 drives the adjusting frame 803 to move through the connecting rod 805, and the adjusting frame 803 slides along the inner wall of the limit frame 802. The displacement of the adjusting frame 803 drives the tension wheel 804 to move, and the displacement of the tension wheel 804 adjusts the tension of the yarn (in this threading mode, the lower limit position of the tension wheel 804 should not be lower than the first guide wheel 6); the positioning block 809 is displaced by the elastic force of the first spring 810 and engages with the first spur gear 808, and the clamping block 811 is engaged with the positioning block 809 by the elastic force of the second spring 812 to prevent the positioning block 809 from moving downward, thereby fixing the first spur gear 808.

[0032] In actual use, the yarn can also be passed through the top of the first guide wheel 6 and the second guide wheel 7 respectively, and in this process, the yarn passes through the bottom end of the tension wheel 804; or the yarn can be passed through the bottom ends of the first guide wheel 6 and the second guide wheel 7 respectively, and in this process, the yarn passes through the top end of the tension wheel 804; the above two threading methods can also enable the adjustment mechanism 8 to adjust the tension of the yarn.

[0033] Please refer to Figures 6 to 8 The driving mechanism 9 includes a mounting frame 901, which is fixedly connected to one end of the top of the base 1.

The displacement of the lower pressure rod 813 pushes the card block 811 to move, causing squeezing of the second spring 812.
