The single yarn packages to be combined are twisted by the respective first twisting spindles, then are twisted and wound by the second twisting spindle after passing through the single yarn guide part, the doubling yarn guide part, the conveying roller and the doubling yarn guide part.
However, in any production mode, when two or more strands of yarns are twisted, one strand of yarn in one group is broken, and the rest yarns are not broken, so that the strand-missing yarn is caused, and if a turner cannot find the yarn in time, waste yarns and raw materials are wasted. Yarn breaks typically occur when the twisting spindle is started up to its operating speed, especially when a yarn having a large number of individual filaments or consisting of a friction-sensitive material such as polypropylene or polyester is used for twisting, the more frequently a yarn break occurs. The machine needs to be stopped to guide yarns again after yarn breakage, the operation is complicated, spun yarns are wasted, and when the yarn breakage frequently occurs on a station, the efficiency of yarn folding equipment has an overall adverse effect.

and step four, starting a variable frequency motor in the rack 401 to rotate the wire groove drum 408, driving the wire groove drum 408 to drive the take-up drum 509 to rotate oppositely, starting automatic take-up by the take-up drum 509, automatically rotating the fine yarn drum 106 to supply yarn, and finally combining multiple strands of spun yarns into one yarn.
The working principle of the invention is as follows:
when the device is used, the thicker end of the thin yarn cylinder 106 is downwards sleeved on the yarn cylinder rotating shaft 102, the bottom end of the thin yarn cylinder 106 is contacted with the yarn cylinder clamping disc 103, the clamping slide block 105 in the yarn cylinder clamping disc 103 is positioned in the thin yarn cylinder 106, the thin yarn cylinder 106 is pressed downwards, the clamping slide block 105 is extruded by the yarn cylinder rotating shaft 102, the clamping slide block 105 slides along the clamping disc sliding groove 104 to clamp the thin yarn cylinder 106, and when the device performs thread-combining work, the thin yarn cylinder 106 and the yarn cylinder rotating shaft 102 can rotate together to supply yarns; when the spinning frame is disassembled, the spinning bobbin 106 is directly pulled out upwards, the clamping slide block 105 is extruded by the spring to slide towards the center of the spinning bobbin rotating shaft 102, and the clamping slide block 105 is automatically separated from the spinning bobbin 106;
the single-strand spun yarn is poor in strength and easy to break, the spun yarn sequentially passes through the first yarn guide rod 108, the second yarn guide rod 204 and the third yarn guide rod 205, the spun yarn is immersed in water in the water tank 201, and the tensile strength of the wetted spun yarn is effectively enhanced; the single-strand spun yarn passes through the yarn guide sliding block 305, when the spun yarn is subjected to a large pulling force, the yarn guide sliding block 305 slides downwards to compress the spring in the yarn plate sliding groove 304, and the large pulling force on the spun yarn can be effectively decomposed; the lifting shaft 308 is jacked up by a spring in the thread-combining platform 301, when the spun yarn passes through the yarn-guiding tension wheel 307, the yarn-guiding tension wheel 307 lifts the spun yarn to provide a part of tension for the spun yarn, and when the spun yarn is subjected to a large tension, the yarn-guiding tension wheel 307 moves downwards to decompose a part of tension by compressing the spring below the lifting shaft 308;
the spun yarn is combined into a thin yarn after passing through the yarn collector 312, the thin yarn finally reaches the inside of the wire guide groove drum 408 through the wire guide wheel 313, the output end of a variable frequency motor in the rack 401 is fixedly connected with a driving pulley 404, the driving pulley 404 is driven to rotate when the variable frequency motor is started, the driving pulley 404 drives a driven pulley 405 to rotate through belt transmission, the driven pulley 405 drives a groove drum shaft 406 to rotate, the groove drum shaft 406 finally drives the wire guide groove drum 408 to rotate, the thin yarn can swing back and forth during the rotation of the wire guide groove drum 408, the wire guide wheel 313 is rotatably connected with the yarn combining table 301 through the guide wheel seat 314 and the guide wheel shaft 315, the wire guide wheel 313 can also rotate along with the thin yarn to change the wire guide direction when the direction of the thin yarn is changed, the friction between the thin yarn and the wire guide wheel 313 is reduced, and the breakage of the thin yarn caused by larger friction is prevented;
the wire drum supporting mechanism 5 makes the wire drum 509 and the wire groove drum 408 rotate in opposite directions by closely contacting and rubbing the wire drum 509 and the wire groove drum 408, so that the function of automatically taking up the wire drum 509 is realized, the cross rod 505 is rotatably connected with the sleeve 503 through the short shaft 504, the angle between the axis of the wire drum 509 and the axis of the wire groove drum 408 can be adjusted, and the wire drums 509 with different sizes at two ends can be installed and used.
