Further, a damping sheet is arranged on the side wall of the jack and is in contact with the variable resistor.

The working principle is as follows: after the skeins are arranged on the pull ropes bound on the two skein discs, workers twist the adjusting discs to enable the pull ropes to be in a proper tightening state. The adjusting disk is then fixed when the plug pin is inserted. At the moment, the connecting rod sleeved on one of the pull ropes moves along the radial direction of the rotating shaft under the action of the pull rope, the resistance in the variable resistor connected with the connecting rod is driven to change, then the current detector electrically connected with the connecting rod detects a current value, and the current value is converted into a driving signal to be transmitted to the driving motor electrically connected with the connecting rod so as to control the rotating speed of the driving motor. It should be noted that the utility model discloses in, acquiescence hank yarn diameter is big then the detection current is big, and the controlled back rotational speed of driving motor is low, and the hank yarn diameter is little then the electric current that detects is little, and the controlled back rotational speed of driving motor is high to reach the balanced state of a linear velocity.

Has the advantages that: through the structure, the yarn outlet speed of hank yarn is relatively stable, and the quality of yarn on the spindle after rewinding is further ensured.

The rewinding machine shown in fig. 1 and 2 comprises a body 100 and a yarn releasing device 200. The yarn releasing device specifically comprises a rotating shaft 210 rotatably arranged on the upper part of the body, and one end of the rotating shaft extends out of the body and is in transmission connection with a driving motor 220 fixed beside the body. Two pieces of capstans 230 are arranged on the rotating shaft coaxially with the rotating shaft, and are arranged oppositely with a gap. Meanwhile, an adjusting disc 240 is rotatably arranged on the rotating shaft, a plurality of pull ropes 250 are uniformly distributed on the adjusting disc in the circumferential direction, and each pull rope penetrates through the outer edge of one of the winches and then is fixedly connected to the outer edge of the other winch. The pulling rope is in a spoke shape after being fixedly connected. It should be noted that the adjusting plate is fixedly connected through a bolt. Specifically, a plurality of bolt holes 231 are uniformly distributed in the axial direction on one winch close to the adjusting disc, and one bolt 260 penetrates through the adjusting disc and then is inserted into one bolt hole. Meanwhile, in order to realize automatic adjustment of the skein discharging speed, a detection mechanism 270 is arranged between the two winches. Specifically, the detecting mechanism includes a mounting block 271 fixedly connected to the shaft, a socket 272 formed in the mounting block and radially disposed along the shaft, and a variable resistor 273 installed in the socket. Specifically, the variable resistor includes a movable plate 274 fixedly installed in the insertion hole, a resistive rod 275 slidably inserted in the insertion hole, and a fixing plate 276 provided at one end of the resistive rod. In the implementation process, the resistance value of the variable resistor is adjusted by sliding the resistance rod along the radial direction of the rotating shaft. In order to make the radial sliding of the resistance rod correspond to the diameter of the skein, a connecting rod 277 connected with the resistance rod is arranged at one end of the resistance rod, a circular ring 278 is arranged at one end of the connecting rod far away from the variable resistor, and the pull rope passes through the circular ring to realize the sleeve connection of the resistance rod and the skein. When the pull rope is tightened under the action of the skein and the adjusting disc, the connecting rod is stretched to drive the resistance rod to slide. It should be noted that a current detector 279 is further disposed on the rotating shaft, the current detector is electrically connected to the variable resistor through a wire, a power supply is built in the current detector, so as to convert the resistance change of the variable resistor into a current change, and then the current detector converts the current change into a control signal and transmits the control signal to a driving motor electrically connected to the current detector to control the rotating speed of the driving motor.
