[0039] The guide device 23 includes a transmission card shaft 231, and a guide synchronous pulley 235 is fixedly arranged at the center of the inner end surface of the transmission card shaft 231. A connecting turntable 233 is symmetrically arranged on the outer end surface of the transmission card shaft 231 with the guide synchronous pulley 235 as the center, and a positioning guide groove 232 is opened on the inner end surface of the connecting turntable 233, and arc-shaped sliding grooves 234 are equidistantly opened on the inner end surface of the connecting turntable 233.

[0040] The positioning guide groove 232 is equal to the positioning slide groove 26 in thickness, and the alignment slide 225 is slidably engaged with the inner end surface of the positioning guide groove 232 through the positioning slide groove 26.

[0044] Working principle: When in use, the user can pass the yarn to be guided through the front and rear two groups of feed barrels 4 in turn, and pass the yarn through the three groups of guide yarn wheels 222 in the middle at the same time, so as to facilitate the subsequent adjustment of the real-time tension of the yarn guide. When adjusting the guide tension of the yarn, the staff can start the servo motor 3. At this time, the servo motor 3 can drive the internal transmission card shaft 231 to rotate, and at the same time, the transmission card shaft 231 can synchronously drive another group of guide synchronous belt wheels 235 to rotate through the guide synchronous belt wheel 235. At this time, the two groups of guide synchronous belt wheels 235 can synchronously drive the two groups of connecting turntables 233, so that the connecting turntable 233 can synchronously drive the three groups of arc-shaped slide grooves 234 to rotate. When the arc-shaped slide groove 234 rotates The arc-shaped slide groove 234 can be limited by sliding with the limit slide shaft 226, and then the positioning slide groove 26 can limit the positioning slide seat 225, thereby adjusting the tension of the guide yarn supported by the limit support 224 and the guide yarn wheel 222. At the same time, since the three groups of transmission card shafts 231 are fixedly arranged, the three groups of parallel guide synchronous belt pulleys 235 can synchronously adjust the guide yarn wheel 222 to guide the yarn. When the yarn tensioning force is floatingly regulated, the guide yarn wheel 222 can elastically slide inside the limit support 224 through the support guide seat 223 and the reset spring 227, so that the guide yarn wheel 222 can float forward and backward under the guidance of the yarn, thereby dynamically regulating the tensioning force of the yarn.
