Abstract
Description
Technical Field
[0001] The utility model relates to a warp knitting machine, in particular to a yarn storage device of the warp knitting machine. Background Art
[0002] When the warp knitting machine is in normal operation, the warp yarn is unwound from the warp beam and fed into the loop forming system according to a certain warp feeding amount for the loop forming machine to weave. Figure 1 As shown, the yarn is unwound from the yarn feeding beam, passes through the yarn guide rod 1', reaches the first yarn guide cap 2', then reaches the second yarn guide cap 4' on the tension plate 3', and finally reaches the loop forming mechanism 10' for looping. The yarn will be loose and tight during the looping process. At this time, the yarn guide cap swings up and down to maintain a stable tension by relying on the elasticity of the tension plate. When the yarn feeding amount is large, the tension plate is pulled downward, and when the yarn feeding amount is small, the tension plate is reset upward to always maintain a certain tension value. In actual production, when the lateral displacement exceeds 1 inch, the warp feeding amount often exceeds 10000mm / Rack. If the needle movement exceeds the swing stroke of the tension plate, it is easy to cause missed needles, broken yarns, etc., and the yarn feeding cannot be carried out normally.
