It is desirable in warp knitting machines to use warp yarns that are pulled from the warp beam during the manufacture of the knitwear. The warp beam typically includes a rotating shaft and a plurality of pan heads disposed on the rotating shaft, the pan head being smaller than the working width of the machine.
Installed side by side on the rotating shaft and tensioned by means of the clamping tensioning member, the disk head is fixed to the rotating shaft and cannot rotate or slide relative to the rotating shaft, for example, the disk head and the rotating shaft are axially slid relative to each other, and the disk head is The path when the warp is released is unstable, which causes troubles in which the warp yarns are wound together.
At present, when working, because a plurality of pan heads are fixed with the rotating shaft, the pan head rotates together when the rotating shaft rotates, so that the warp yarn wound on the pan head is released and enters the warp knitting part of the warp knitting machine, but in this way, the pan head is in operation The number of warp yarns on the same must be the same, and the warp yarns must also be the same.
If there are many warp yarns on the pan head, and the number of warp yarns on the pan head is small, and all the pan heads rotate together with the rotating shaft, the pan head with a large number of warp yarns The linear velocity of the upper warp yarn is greater than the linear velocity of the warp yarn on the pan head with a small number of warp yarns, resulting in different warp yarn lengths released at the same time, which causes the longer warp yarns to be untensioned, thereby affecting the entire knitting. process.
