Winder with tensioning function

The utility model discloses a winder with a tensioning function. Case, a plurality of transmission gears and a plurality of execution gears are mounted in the case; the transmission gear is in meshedconnection with an execution gear; an inner ring of the transmission gear is in key connection with the transmission shaft; the bottom of the output shaft penetrates through the bottom of the case; every two adjacent output shafts form a winding set, the two output shafts in the same winding set are the first output shaft and the second output shaft respectively, the first output shaft is sleevedwith a first winding roller and a second winding roller, silk threads are wound on the first winding roller, and the silk threads are wound out of the first winding roller and wound on the second winding roller. The winding device has the advantages that winding among the multiple wire rollers is achieved synchronously, only one driving device is adopted for driving, tensioning is achieved on thewinding device through chan
