[0022] Compared with the related art, the yarn sizing machine broken wire protection device has the following beneficial effects:

[0023] In the present invention, the described wire breakage protection device for a sizing machine has a wire breakage protection mechanism. When the yarn is wound around the guide roller during transportation, the tension on the yarn can be decomposed into a horizontal tension and a vertical tension. The vertical tension will drive the guide roller to move upward, which will cause the second spring to be stretched, and the winding arc of the yarn on the guide roller will be reduced. After the second spring is pulled, the length of the yarn wound around the guide roller will be reduced, which reduces the probability of wire breakage caused by the friction effect, thereby providing a better wire breakage protection mechanism for the yarn. At the same time, when the tension increases When the yarn is pulled out of the guide roller, the sliding seat will be driven to slide adaptively inside the slot, changing the arc of the yarn winding on the guide roller and reducing the possibility of the yarn breaking during transportation. At this time, the force on the first pressure sensor at the end of the first spring is the elastic or tensile force caused by the deformation of the first spring. The controller can calculate the tension value on the yarn according to the force decomposition principle through the tension value on the first pressure sensor and the second pressure sensor. When the tension value on the yarn exceeds the standard, the controller will control the corresponding alarm light on the side of the mounting table to light up, indicating that the tension of this group of yarns exceeds the standard and may cause the yarn to break, prompting the staff to deal with it in time.
