Weft storage device high in adaptability

Abstract

The invention provides a weft storage device with strong adaptability, which includes a yarn storage base, a yarn guide device, a yarn introduction port, a yarn storage drum, a yarn withdrawal device, a yarn guide eye, a photoelectric detector, and a mirror reflector. The yarn device includes a spring piece, a first support shaft, a second support shaft, and a cover. The lower end of the yarn guide device is connected to the upper end of the yarn introduction opening, and the lower end of the yarn introduction opening is connected to the upper end of the yarn storage drum. , the yarn storage drum includes an upper yarn storage drum and a lower yarn storage drum, the inner wall of the lower yarn storage drum is provided with several yarn drawing strips, the lower end of the yarn storage drum is connected to the upper end of the yarn withdrawing device, The yarn unwinding device includes a yarn unwinding guide, a yarn unwinding gripper, and a yarn unwinding cylinder. An adaptable weft storage device of the present invention can effectively control the weft insertion tension and weft insertion length, thereby improving the overall quality of the fabric and increasing the use value of the fabric, and at the same time the length of the yarn storage drum can be properly adjusted , to meet the weaving requirements of fabrics of different widths.

Description

【Technical field】 [0001] The invention relates to the technical field of textile machinery, in particular to a weft feeder with strong adaptability. 【Background technique】 [0002] Strictly controlling the constant weft tension in the weaving process is crucial to improving fabric quality. With the rapid development of shuttleless looms and the continuous improvement of weft insertion speed, the problem of controlling the weft yarn tension is more prominent, and the use of weft feeders has emerged as the times require. If the weft yarn is directly drawn from the bobbin during weft insertion, since the weft insertion process takes about 120 to 180 degrees of one revolution of the main shaft, the unwinding speed of the weft yarn at this time is equivalent to 2 to 3 times the weft insertion rate, and the weft insertion Intermittent weft yarn unwinding and continuous reduction of bobbin unwinding radius lead to large fluctuations in weft yarn tension, resulting in weft yarn bre...

AI Technical Summary

Problems solved by technology

[0003] However, the tension and length of the weft insertion of the existing weft feeder are not easy to control, which reduces the quality of the fabric, and the length of the yarn storage drum is fixed, which cannot meet the weaving requirements of different width fabrics.
