The automatic warp tying machine consists of three parts: a fixed frame, a movable frame, and a knotting machine head. The wire feeding device is a key component of the warp tying machine, and its performance directly affects the quality and production efficiency of textiles. The existing wire feeding device cannot flexibly adjust the tension of the yarn during wire feeding, and it is easy to break the wire. Secondly, the yarn is usually wrapped around the yarn tube and placed, which causes wrinkles on the yarn, thus affecting the effect and quality of warp tying.
