一种喷水织机积极式后梁滚筒装置
本技术涉及一种喷水织机,特别涉及一种喷水织机积极式后梁滚筒装置。
技术介绍
喷水织机是依靠高压水流与纱线之间的摩擦力,带动纬纱高速通过梭口完成引纬动作。喷水织机以噪音低、织造成本低、速度高、效率高而得到广泛应用。目前选纬数最多3色。可织造各种疏水性纤维织物,特别适合大批量织物的生产。喷水织机主要由机架、主传动系统、引纬系统、开口系统、打纬系统、送经系统、卷取系统、绞边装置、剪刀装置和撑布装置等组成。现有技术中的喷水织机,其后梁滚筒多采用消极式结构,其工作原理为:当经纱开口时,通过送经弹簧的拉伸来补偿经纱因开口引起的伸长,防止经纱拉断,这种结构用来织造平纹织物时是合适的,因为所有经纱都来参与拉动送经弹簧,使弹簧拉伸,后梁摆动。然而上述消极式后梁滚筒在实际应用中存在如下不足之处:(1)容易引起后梁滚筒与开口机构和打纬机构的动作不同步;(2)需要的经纱织造张力较大,只适合于化纤、长纤类织物,而不适用于短纤和玻璃纤类织物;(3)当需要织造高纬密布时需要的打纬力大。
