[0043] In this embodiment, by setting up an electric cylinder 901, a positioning frame 902, and a tensioning roller 903, the yarn between the two positioning rings 8 can be pushed downward to tighten the yarn and further improve the accuracy of detection.
[0044] The implementation principle of this utility model is as follows: In use, the yarn unwinding roller 404 to be tested is inserted into the surface of the positioning post 401. The yarn is pulled out from the surface of the yarn roller and then passes through the left positioning ring 8, the tensioning roller 903, and the right positioning ring 8 in sequence. It is then fixed to the surface of the external winding device. The external winding device is then started to slowly wind up the yarn. At the same time as winding, the thickness of the yarn is detected by the laser scanner 3. When the yarn between the two positioning rings 8 becomes slack, the control switch of the electric cylinder 901 is activated. The electric cylinder 901 drives the tensioning roller 903 to move downward, and the tensioning roller 903 pushes the yarn between the two positioning rings 8 downward. This method tightens the yarn, further improving the accuracy of the detection. When there is a deviation between the yarn and the laser scanner 3, the handle is turned, which drives the turntable 502 to rotate. The turntable 502 drives the threaded rod 501 to rotate, the threaded rod 501 drives the threaded sleeve 503 to move, the threaded sleeve 503 drives the support plate 504 to move, the support plate 504 drives the push plate 505 to move, and the push plate 505 drives the horizontal plate 6, the vertical plate 7, and the positioning ring 8 to move. This adjusts the position of the positioning ring 8 and the yarn, enabling the laser scanner 3 to accurately detect the yarn, avoiding yarn deviation and improving detection accuracy. This method is convenient for yarn adjustment, has good positioning effect, and high detection accuracy.
