Traverse yarn guide device and yarn guide method

Abstract

The invention provides a traverse yarn guide device and a yarn guide method. The traverse yarn guide device comprises a yarn guide and a traverse drive mechanism, and is characterized in that the yarn guide is formed by two guiding rods and a fixed seat which are connected, and the fixed seat is connected with the traverse drive mechanism of the yarn guide; an upper yarn guide plate layer and a lower yarn guide plate layer are arranged at the front of the yarn guide, and the left end of the upper yarn guide plate layer is fixedly connected with the lower yarn guide plate layer; the top side of the lower yarn guide plate layer is of a straight side parallel to the axis of a rotary bobbin, and the top side from the left end to the middle of the upper yarn guide plate layer is of a straight side parallel to the axis of the rotary bobbin; the top side of the right end of the upper yarn guide plate layer is of a curved side which gradually turns up towards the right upper part, and the curved side and the right side of the upper yarn guide plate layer form smooth transition; the two guiding rods are higher than the straight sides of the tops of the lower yarn guide plate layer and the upper yarn guide plate layer, and the left-side guiding rod is higher than the right-side guiding rod; and the highest point of the right end of the upper yarn guide plate layer is slightly higher than the right-side guiding rod but is lower than the left-side guiding rod. The traverse yarn guide device has reasonable and simple structure, and can effectively guide yarns into the yarn guide; and the yarn guide method is simple and reliable.

Description

technical field [0001] The invention belongs to the technical field of textile equipment manufacturing, and relates to the improvement of a traversing yarn device and a yarn guiding method of a winding device of a textile machine for producing cross-wound bobbins, specifically a traversing yarn guiding device and a yarn guiding method . Background technique [0002] In the automatic winding equipment, when the yarn traverse device is used in the bobbin winding process, a yarn guide and a matching device are required. When it is necessary to introduce the yarn into the yarn guide, there must be an appropriate device to cooperate with the action of the yarn guide to complete the introduction of the yarn, and the introduction action is required to be effective and reliable. In the bobbin winding process of the existing automatic winder, some fork-shaped swinging yarn guides are used to traverse the yarn, and the trajectory of the yarn is arc-shaped, and the reliability of yarn...

AI Technical Summary

Problems solved by technology

In the bobbin winding process of the existing automatic winder, some fork-shaped swinging yarn guides are used to traverse the yarn, and the trajectory of the yarn is arc-shaped, and the reliability of yarn introduction into the yarn guide is poor.
