In the large elasticizer or the small elasticizer, the yarn is discharged through a third roller, passes through a yarn detector and an oiling assembly in sequence, and is fed into a winding mechanism for winding.
In an elasticizer as shown in CN101984163A, the third roller is arranged on the main frame, the oiling component is fixed on the pedal component, the winding mechanism is arranged on the auxiliary frame, the yarn coming out from the third roller can be fed into the oiling component in an almost straight state, and the yarn coming out from the oiling component is fed into the winding mechanism in an almost vertical state. Therefore, the yarn guide wheel is only used for guiding the yarn, but the yarn coming out of the oiling assembly is almost vertically fed into the winding mechanism, so that the wrap angle between the yarn and the yarn guide wheel is too large, namely the contact distance (time) between the yarn and the yarn guide wheel is too long, the yarn running at high speed can cause abrasion to the yarn guide wheel after long-term use, and through practical detection, the yarn can form grooves with different depths on the surface of the yarn guide wheel, which has great influence on the running of the yarn.

The working principle of the invention is as follows:
the invention improves a yarn guide mechanism before winding of the elasticizer, and the yarn guide mechanism is arranged between an oiling assembly of the elasticizer and a winding mechanism. Wherein, in big elasticizer, through improving current fixed yarn guide wheel for rotation type filar guide, in little elasticizer, set up first filar guide for fixed or rotation type, the second filar guide is rotation type filar guide.
The advantages of this arrangement are: when the yarn passes through in the silk track recess of rotation type yarn guide, driven rotation type yarn guide and rotated, at this moment the motion of yarn through contact point in the silk track recess can divide into the closed motion of two minute motions: a combined rolling and sliding motion. Namely: the motion of the spinning of the yarn path is rolling relative to the motion of the yarn, and the relative motion of the yarn instantaneously passing through a certain point of the yarn path is sliding. Because the rotary yarn guide is driven to rotate by the friction force generated by the movement of the yarn in the yarn channel, the rotary yarn guide is driven to rotate by power only when the yarn movement speed is higher than the rotation speed of the yarn channel, and the relative movement of the yarn relative to the yarn channel generates the friction force to cause the rotary yarn guide to rotate, so the movement of the yarn passing through the yarn channel is the combined movement of the sliding movement and the rolling movement. In this way, the friction of the yarn on the thread path of the rotary thread guide is converted into rotation of the thread guide, thereby reducing the abrasion of the yarn on the thread path of the thread guide.
