The positioning rods 601 are used to position the angle of the adjusting wheel 7 when it is lifted up and down, and the spring 602 is used to push the adjusting wheel 7 to rise upward, thereby driving the yarn to be lifted and tightened. An adjusting wheel 7 is provided on the outside of the extension frame 3, and a positioning block 8 is provided on one side of the adjusting wheel 7. Slide blocks 801 are provided on both sides of the positioning block 8. When the yarn tension is relaxed due to speed changes, the adjusting wheel 7 is driven to rise upward by the spring 602, driving the yarn to be lifted and tightened. When the yarn is completely relaxed, the adjusting wheel 7 will rise to the inner cavity of the cam 401 embedded in the adjusting wheel 7, thereby clamping the yarn in the adjusting wheel 7 and cooperating with the damping plate 402 outside the cam 401 to slow down the yarn conveying speed, thereby tightening the yarn; when the yarn tension increases and tightens, the adjusting wheel 7 is driven downward by the tension of the yarn to provide a buffer space for tightening the yarn.
[0021] In this embodiment, all electrical components are controlled by conventional controllers.
[0022] For example, please refer to Figure 1-3The two driving wheels 2 are rotatably connected to the outer wall of the base frame 1 through a connecting shaft, the extension frame 3 is welded to the top of the base frame 1 by welding, the top roller 4 is connected to the outer wall of the extension frame 3 by bolts, the cam 401 is sleeved on the outer wall of the top roller 4, and is rotatably connected to the top roller 4 through a bearing, the two damping plates 402 are inlaid with the inner wall and outer wall of the cam 401, the cam 401 can be moved by the adjusting wheel 7 and embedded in the inner cavity of the adjusting wheel 7, the positioning groove 5 is communicated with the slide grooves 6 on both sides, the positioning rod 601 is located in the slide groove 6, and is connected to the inner wall of the slide groove 6 by bolts, the Both ends of the spring 602 are connected to the inner wall of the slide groove 6 and the slider 801 by welding. The positioning block 8 is rotatably connected to one end of the adjusting wheel 7 through a bearing. The other end of the positioning block 8 extends into the positioning groove 5 and is slidably connected to the inner wall of the positioning groove 5 through a slide rail. The slider 801 is connected to the outer wall of the positioning block 8 by a bolt. The other end of the slider 801 extends into the slide groove 6 and is slidably connected to the inner wall of the slide groove 6. The yarn is wound around the outside of the driving wheel 2 and the adjusting wheel 7 at both ends of the base frame 1. When the adjusting wheel 7 rises to abut against the cam 401 through the spring 602, the yarn in the inner cavity will be squeezed by the cam 401. When in use, the yarn is first transported to pass through the driving wheel 2 and the internal adjusting wheel 7. The adjusting wheel 7 cooperates with the spring 602 to lift and tighten the yarn to ensure the tension during transportation. When the tension of the yarn changes due to changes in the transportation speed, the adjusting wheel 7 will follow the spring 602 and the pulling force of the yarn to move up and down, thereby stretching or buffering the yarn. As a result, the tension of the yarn will also change to be stable. The adjusting wheel 7 follows the change of the yarn to adjust, so that the tension of the yarn is kept within the set area, ensuring normal transportation of the yarn while protecting the yarn.
[0023] The working process of the utility model is as follows: when in use, the yarn is first transported to pass through the driving wheel 2 and the internal adjusting wheel 7. The adjusting wheel 7 cooperates with the spring 602 to lift and tighten the yarn to ensure the tension during transportation. When the tension of the yarn changes due to the change of the transportation speed, the adjusting wheel 7 will follow the spring 602 and the pulling force of the yarn to move up and down, thereby stretching or buffering the yarn, and the tension of the yarn will also change to be stable. The adjusting wheel 7 follows the change of the yarn to adjust, so that the tension of the yarn is kept within the set area, ensuring the normal transportation of the yarn while protecting the yarn. The utility model realizes the support of the yarn through the adjusting wheel, and follows the movement and adjustment position when the tension of the yarn changes due to the adjustment of the transportation speed, so that the tension of the yarn is kept within the set range.
