When the guide roller 2 drives the cam 52 to rotate one circle, the connecting rod 56 can drive the slider 53 to slide up and down once. At this time, the slider 53 slides upward and cooperates with the connecting rod 57 and the counting lever 55 to make the counter 51 complete a counting. When the cam 52 rotates, it will drive one end of the connecting rod 56 to make a circular motion around the guide roller 2, and make the other end of the connecting rod 56 reciprocate to push and pull the slider 53, so that the slider 53 slides back and forth on the side wall of the processing table 1.

The inner wall of the processing table 1 is slidably connected with two groups of slide plates 63, and the inner walls of the two groups of slide plates 63 are threadedly connected to the outer wall of the bidirectional screw rod 61. The bidirectional screw rod 61 is rotated by the handle 62, and the rotation of the bidirectional screw rod 61 will drive the two groups of slide plates 63 to slide synchronously in opposite directions on the inner wall of the processing table 1.

The bidirectional screw rod 61 is rotatably connected to the penetration of the processing table 1.
[0025] Working principle: During the production process of yarn, the yarn passes through the bottom of the limiting roller 4 on the right side of the guide roller 2, and then passes through the top of the guide roller 2, and then passes through the bottom of the limiting roller 4 on the left side of the guide roller 2, and the yarn is placed on the outer wall of the rubber pad 3. At this time, when the yarn is wound, it will drive the guide roller 2 and the rubber pad 3 to rotate. The guide roller 2 will drive the cam 52 to rotate synchronously. The cam 52 will drive one end of the connecting rod 56 to make a circular motion around the guide roller 2, and make the other end of the connecting rod 56 push and pull the slider 53 back and forth, so that the slider 53 slides back and forth up and down on the side wall of the processing table 1. At the same time, the slider 53 will push and pull the connecting rod 57 back and forth, so that the connecting rod 57 pushes and pulls the counting lever 55 back and forth, so that the counting lever 55 swings back and forth up and down. At this time, the counter 51 can be used to record the number of swings of the counting lever 55, and then the number displayed on the counter 51 is multiplied by the outer wall diameter of the rubber pad 3 to obtain the conveying length of the yarn.
[0026] By rotating the bidirectional screw rod 61 through the handle 62, the bidirectional screw rod 61 will drive the two sets of slide plates 63 to slide synchronously in opposite directions on the inner wall of the processing table 1. At the same time, the two sets of slide plates 63 will drive the two sets of guide plates 64 to move synchronously, so that the distance between the two sets of guide plates 64 can be adjusted. According to the number and width of the yarn, the two sets of guide plates 64 are adjusted to the appropriate position. The two sets of guide plates 64 can be used to guide the two sides of the yarn so that the yarn can be transported stably while maintaining tension.
