编织帘织机的自动化改进设计

Automation improvement design of weaving curtain loom

针对目前编织帘织机在选纬和引纬过程中仍依赖于人工操作,自动化水平较低的问题,自主研发设计了一种集纬料的存放、筛选、选取、输送于一体的自动选纬装置。通过对自动选纬装置关键零件结构设计要求的详细分析,在SolidWorks软件平台上进行三维建模和虚拟装配,并利用SolidWorks自动生成的相应二维图纸进行零件的加工和装配,成功搭建了自动选纬装置。同时,将现有易导致织物纬密不匀、经纱动态张力不匀等一系列问题的消极式机械卷取送经机构配套升级为电子卷取送经系统,结合编织帘织造的工艺要求,自行设计了编织帘织机的控制方案。研究结果表明,该方案结构简单,成本低,品种适应范围广,有利于提高织机的自动化水平。

At present,the weaving curtain loom still requires manual operation during the process of weft selection and weft insertion involved in the low level of automation of loom. An automatic weft selection device of woven shade loom integrating storage,screening,selection and transportation of weft material was designed and developed independently. The Solid Works software platform was adopted to conduct three-dimensional modeling and virtual assembly operations based on the detailed analysis of the structural design requirements of key components in the automatic weft selection device,and the corresponding two-dimensional drawings were automatically generated to obtain the processing and assembly of the components,and the automatic weft selection device was successfully built. At the same time,the negative take-up and let-off mechanism in loom that is prone to result in a series of problems such as the unevenness of weft density and warp tension is upgraded with an efficient and appropriate electronic take-up and let-off system,and then combined with the technical requirements of weaving,the control scheme of the weaving curtain loom is designed. The results show that the scheme has the advantages of simple structure,low cost and wide variety adaption range,which facilitates improving the automation level of the loom.
