Description

Self-adaptive tension adjusting warping machine

Technical Field

The invention relates to the technical field of warping machines, in particular to a self-adaptive tension adjusting warping machine.

Background

Warping is a process in which a certain number of warp yarns are wound in parallel on a beam or beam according to a predetermined length and width. The most important thing in the warping process is to control the consistency of the tension of tens or hundreds of warp yarns wound on the warp beam at the same time.

However, since the distances from the point of each yarn tube on each vertical row to the yarn guide frame are different, the distances from the yarn tubes on the transverse rows to the yarn guide frame are also different (the yarns on the yarn tube frames are sequentially arranged from back to front and from outside to inside on the yarn guide frame). The distance from the yarn guide frames to the wind-up roller is different, so that the required tension from the yarn on each yarn drum to the wind-up roller is inconsistent.

The existing tension regulator is mainly divided into two types, one type is independently regulated, and the independent regulation is time-consuming and labor-consuming. The other is a unified regulation type. However, the tension provided by the current unified tension regulator is consistent, and because the tension required by the yarns at each position is different, the tension of the yarns at different positions is deviated before reaching the winding roller, and the yarns inevitably have the phenomena of wrinkling, loosening and the like when being wound.
