Description
Technical field
The present invention relates to a kind of weaving device, particularly relate to a kind of cylinder yarn locking device.
Background technology
Conically shaped yarn has easily unwinding, is difficult to the plurality of advantages such as off-clip, and in whole spinning technological process, conically shaped yarn is indispensable yarn type of organization, and due to the needs of next procedure, many operations often require that making conically shaped yarn.
Cylinder yarn, in winding process, is that cylinder yarn twines more and more along with the yarn being wound around gradually increases on winch spool.Reality can problem is encountered that the bad problem of molding that a yarn is wound around, one of them problem is that on a yarn, the yarn of internal layer (inner ring) is gradually tied tight by the yarn of outer layer (outer ring), so internal layer yarn easily forms fold on the end face at cylinder yarn two ends, getting loose occurs in even internal layer yarn, if and internal layer yarn gets loose, the also easy inner layer of outer layer yarn is subsided, and the molding causing a yarn is bad, rear road is during unwinding, and the problem that unwinding is difficult will occur in this yarn.The bad reason of above-mentioned molding is exactly the tightness that the tightness that is wound around of outer layer yarn is wound around more than internal layer yarn, causes internal layer yarn to be tied tight by outer layer yarn and forms ripple or the pleated structure of annular.Good cone yarn forming structure constantly should be carried out along with what yarn was wound around, is gradually reduced winding yarn tension force, forms cylinder knot structure tight inside but loose outside.
Above-mentioned cylinder knot structure tight inside but loose outside needs corresponding device or mechanism to realize.
The winding method of the present invention can use the winding technique scheme such as Chinese patent CN103538965A, and it provides the power of winding by friction roller, provides being uniformly distributed of yarn by yarn guide simultaneously.
