经编机用盘头夹紧装置的设计

Design of Clamping Device on Warp Beam

现有的靠机械刚性螺纹并紧方式设计的盘头,当纱线减少到一定程度时,将会发生经轴打滑现象,须人工调整,否则将会在编织的织物上产生横条或隐横条。针对这一问题,提出采用蝶形弹簧开发一种盘头自动夹紧装置,并介绍了蝶形弹簧设计的要求及计算方法。实践证明,该新式夹紧装置可解决一般夹紧装置不方便和可靠性差的问题,具有一定的实用价值。

For the current warp beam tightened only by simple rigidity of screw thread, when the yarn on that beam reduces to a certain extent, slipping phenomenon will happen, and then it needs manual adjustments. If not, horizontal stripe or hidden stripes will appear on the knitted fabric. Concerning this issue, this paper proposes a clamping device on warp beam based on the belleville spring,and introduces its design requirements and calculation methods. This kind of beam developed in this paper proves to be convenient, reliable and practical.
