In the following embodiment, the digital tension yarn control device 4, the traversing yarn guiding device 5 and the bobbin actively driven winding device 6 are specifically described respectively, and the specific descriptions are as follows:

Digital tension yarn control device: the tension sensor is an online tension sensor, the tension sensor and the overfeeding roller are controlled by the existing computer to form a "computerized active roller", which can constantly control and adjust the yarn during the entire winding process Thread tension, the accuracy of which can reach 0.1 gram, can effectively avoid the adverse effect caused by the change of feeding yarn tension. Technicians can set the tension required for the yarn during winding through the touch screen on the tension control cabinet. During the winding process, the tension will be fed back to the existing overfeed roller control system through the tension fluctuations continuously detected by the online tension sensor. According to the detected tension fluctuation, it continuously changes the rotation speed of the existing DC brushless servo overfeeding motor and the overfeeding roller with small inertia in a corresponding time of milliseconds to keep it in sync with the winding line speed and the set tension. The device and the yarn bobbin active drive winding device form a closed-loop control, which makes the equipment a perfect realization of a precision winding machine with constant linear speed and constant tension winding in a true sense. The continuous automatic adjustment function ensures consistent yarn tension, combined with the "precision winding" and "digital winding" functions of the traversing guide forming device, so as to ensure that the inner and outer yarns of the package and all The bobbins all have the same unwinding tension and density.

Traversing yarn guide forming device: This device adopts advanced servo motor drive technology. The yarn guide is installed on a very durable steel wire rope. The steel wire rope passes through 2 passive wheels and then winds on the driving wheel of the servo motor. Driven by the servo motor High-speed forward and reverse rotation (the yarn guide reciprocates on the wire rope, and its maximum reciprocating speed can reach 800 times/min). The adoption of this technology makes the device compact and simple in structure, small in size, stable in high-speed operation of the steel wire rope, eliminates noise and reduces energy consumption. At the same time, there is no need to add lubricating grease, which reduces the working time and labor intensity of maintenance. Servo motor traversing yarn guide device is adopted, and the reciprocating stroke and yarn bobbin shape of each spindle, each group or the whole machine can be directly selected by the computerized terminal to produce yarn bobbins with different characteristics.

Yarn bobbin active drive winding device: The biggest difference between this device and the traditional friction passive winding is that it changes the slippage of the yarn in the friction winding process during the winding process. The winding of the yarn bobbin is directly driven by the motor with digital encoder closed-loop control, which fundamentally solves the problem of the yarn winding process. The system combined with the servo motor drives the traverse guide forming device, the tension sensor, and the existing DC servo brushless overfeed motor system to drive the overfeed roller, and determined the concept of "new precision winder", the only one that can Winder that controls yarn winding and avoids lapping.
