[0002] Color spun yarn is a kind of yarn with unique color mixing effect, which is made by dyeing the fiber into colored fiber first, and then fully mixing two or more fibers of different colors. In the production process of color spun yarn, winding is a key link, so a winding device is used to wind the color spun yarn.

[0039] like Figures 1 to 10As shown, the detection mechanism 6 includes a detection frame 601, a first screw 602 and a first nut 603. The detection frame 601 is fixed to the outside of the shell 1. The first screw 602 is movably connected inside the detection frame 601. The first nut 603 is fixed to the top of the first screw 602. The second screw 604 is movably connected inside the detection frame 601. The second nut 605 is fixed to the top of the second screw 604.

[0040] like Figures 1 to 10 As shown, the external thread of the first screw rod 602 is connected to the first mounting block 606, and the first infrared position sensor 607 is fixed to the outside of the first mounting block 606, the external thread of the second screw rod 604 is connected to the second mounting block 608, and the second infrared position sensor 609 is fixed to the outside of the second mounting block 608, the outer wall of the first mounting block 606 is close to the inner wall of the detection frame 601, the first mounting block 606 and the detection frame 601 are slidably connected, and the first mounting block 606 is provided with two groups of symmetrical distribution about the central axis of the detection frame 601, the outer wall of the second mounting block 608 is close to the inner wall of the detection frame 601, the second mounting block 608 and the detection frame 601 are slidably connected, and the second mounting block 608 is provided with two groups of symmetrical distribution about the central axis of the detection frame 601.

[0041] The above scheme is adopted: the height of the first mounting block 606 can be controlled by rotating the first nut 603, and the height of the second mounting block 608 can be controlled by rotating the second nut 605, thereby adjusting the height of the first infrared position sensor 607 and the second infrared position sensor 609.

When the tension of the yarn changes, the height of the yarn will change, thereby contacting the infrared light of the first infrared position sensor 607 and the second infrared position sensor 609, so that the rate of infrared light recovery changes, thereby judging that the tension of the yarn has changed. At this time, the alarm inside the control component 5 is started to prompt the user to manually adjust the tension of the device, or automatically adjust the height of the cylinder 409 according to the preset value of the device.

[0042] The working principle and use process of the present invention are as follows: after the yarn is guided by multiple sets of guide rods 3, it is guided by the first guide wheel 404 and the second guide wheel 407 and introduced into the winding drum arranged outside the winding roller 11. At this time, the yarn can be wound by the second servo motor 10, and the first servo motor 402 is started. The first servo motor 402 can drive the reciprocating screw rod 401 to rotate, and then the shape of the reciprocating screw rod 401 drives the first guide block 403 to reciprocate, so that the yarn can be evenly and orderly wound on the collecting drum arranged outside the winding roller 11, and the first mounting block 606 and the first mounting block 607 are connected. The second mounting block 608 is adjusted to a preset tension position by rotating the first nut 603 and the second nut 605. Rotating the first nut 603 can control the height of the first mounting block 606, and rotating the second nut 605 can control the height of the second mounting block 608, thereby adjusting the height of the first infrared position sensor 607 and the second infrared position sensor 609. The output ends of the first infrared position sensor 607 and the second infrared position sensor 609 will emit a section of infrared light, which will be reflected back to the first infrared position sensor 607 through the mirror surface of the first mounting block 606 and the second mounting block 608 opposite to the first infrared position sensor 607. and the receiving end of the second infrared position sensor 609, thereby judging the distance according to the time of sending and receiving, and when the tension of the yarn changes, the height of the yarn will change, thereby contacting the infrared light of the first infrared position sensor 607 and the second infrared position sensor 609, so that the rate of infrared light recovery changes, and then it is judged that the tension of the yarn has changed. At this time, the alarm inside the control component 5 is started to prompt the user to manually adjust the tension of the device, or automatically adjust the height of the cylinder 409 according to the preset value of the device. When the detection component detects that the tension of the yarn has changed, the alarm is turned on. When the position of the yarn is offset, the cylinder 409 is started to extend or contract. The extension of the cylinder 409 will move the second guide wheel 407 upward, thereby compensating for the looser yarn tension. When the cylinder 409 contracts, it pulls the second guide wheel 407 downward to relax the tighter yarn tension and prevent it from breaking. The sliding design of the second guide block 410 and the processing table 2 can adjust the tension of the second guide wheel 407 when it moves. The winding height can be changed by the hydraulic cylinder 7, which is convenient for users to take the wound yarn.
