The yarn 100 is wound on the winding positioning frame 33 in a straight and taut state; after the spinning yarn 100 is wound on the winding positioning frame 33 and is tightly distributed in a square shape, the winding and unwinding are stopped, and the winding positioning frame 33 is set horizontally so that the detection head of the spectrum detector 2 is directly facing the wound spinning yarn 100, and then the spectrum detector 2 can perform spectrum detection on the spinning yarn 100 wound on the winding positioning frame 33; when the spectrum detection is completed, the rotary drive component and the winding and unwinding component are rotated in the opposite direction, and the rotary drive component drives the spinning yarn 100 to rotate in the opposite direction. The dynamic winding positioning frame 33 rotates in the opposite direction to unwind the yarn 100, and the unwinding and winding assembly drives the yarn roll 200 to rotate and wind, so that the yarn 100 is gradually wound on the yarn roll 200. At the same time, the unwinding and winding assembly drives the lifting guide assembly to move up and down reciprocatingly, so that the lifting guide assembly drives the yarn 100 to move up and down, so that the yarn 100 is evenly wound on the surface of the yarn roll 200, and the tensioning assembly can adjust the tension of the yarn 100 being transported, so that the yarn 100 is tightly wound on the yarn roll 200.

During winding, the winding motor 32 drives the winding drive shaft 318 and the winding positioning frame 33 to rotate, so that the winding positioning frame 33 winds the spinning yarn 100, and at the same time, the winding drive shaft 318 drives the driving wheel 319 to rotate, and the driving wheel 319 drives the driven wheel 321 to rotate through the transmission belt 320, thereby driving the translation reciprocating screw rod 35 to rotate. When the translation reciprocating screw rod 35 rotates, the moving seat 36 is driven by the threaded transmission to reciprocate back and forth along the translation reciprocating screw rod 35 and the translation guide shaft 322. At this time, the moving seat 36 drives the support rod 310 and the guide ring 311 to reciprocate back and forth, thereby driving the spinning yarn 100 to reciprocate back and forth through the guide ring 311, so that the spinning yarn 100 is evenly wound on the surface of the winding positioning frame 33.

The guide ring 311 is kept stationary to prevent the reciprocating movement of the guide ring 311 from affecting the tension of the yarn 100 and reducing the difficulty of adjusting the tensioning assembly.

[0028] Furthermore, a positioning hole 316 is provided at one end of the winding positioning frame 33, and a hand-tightening bolt 317 extending into the positioning hole 316 is rotatably installed on the side of the end of the winding positioning frame 33. Before winding the yarn 100, one end of the yarn 100 is inserted into the positioning hole 316, and then the hand-tightening bolt 317 is tightened inward, so that the end of the yarn 100 can be pressed and fixed, thereby making the connection and fixation between the yarn 100 and the winding positioning frame 33 more convenient and quick.
