摘要
为解决一般轻型多臂开口机构因剑麻纱线线密度大、开口负载大而不适配重型宽幅剑麻织机的问题,并适应剑麻织机升级换代的需求,设计了一种重型宽幅剑麻织机伺服驱动多臂开口机构。该机构每页综框均以独立的伺服电动机为动力源,依据电子控制程序灵活地驱动和控制提综装置的运动,从而带动综框升降,形成织口。首先对比剑麻织机现行凸轮开口机构与其他电子多臂开口机构的特点,根据开口原理采用Linkage软件模拟开口运动轨迹,得到新型开口机构结构原型。然后采用AutoCAD软件设计摇臂等主体零件的形状尺寸并确定各零件间的连接方式,并进一步利用Solidworks软件对单台伺服电动机独立驱动一页综框升降的开口系统进行三维建模与仿真,补充完善铰链销等辅助零件及链接关系。在验证设计开口系统的可行性后,使用Solidworks软件设计了8页综框伺服开口机构,并将新型伺服驱动多臂开口机构装配至某企业需要升级改造的重型宽幅剑麻织机上进行工作验证。结果表明,重型宽幅剑麻织机伺服驱动多臂开口机构的力学性能可满足重型宽幅剑麻织机的工作要求,并可通过电子控制程序灵活织造不同品种的小提花剑麻织物产品。
To solve the problem of the general lightweight dobby shedding motion being unsuitable for heavy-duty wide width sisal looms due to the high thread density and opening load of sisal yarn,and to meet the needs of upgrading and replacing sisal looms,a heavy-duty wide width sisal loom servo driven dobby shedding motion is designed.This mechanism corresponds to each page of the integrated frame with an independent servo motor as the power source,and flexibly drives and controls the movement of the lifting device according to the electronic control program,thereby driving the lifting and lowering of the integrated frame and forming a weaving mouth.Firstly,by comparing the characteristics of the current cam opening mechanism and other electronic dobby shedding motion on the sisal loom,a new prototype of the opening mechanism structure is obtained by simulating the opening motion trajectory in Linkage software based on the opening principle.Then,the shape and dimensions of the main components such as the rocker arm are designed using AutoCAD software,and the connection methods between each component are determined.Furthermore,Solidworks software is used to perform 3D modeling and simulation of a servo motor independently driving a page frame lifting and opening system,supplementing and improving auxiliary components such as hinge pins and their linkage relationships.After verifying the feasibility of the designed opening system,Solidworks software is used to design the installation and assembly of various parts of the 8-page frame servo opening mechanism.Finally,the new servo driven dobby shedding motion is assembled on a heavy-duty wide sisal loom that needs to be upgraded and renovated by a certain enterprise for trial weaving verification.The results indicate that the mechanical performance of the servo driven dobby shedding motion of the heavy-duty wide width sisal loom can meet the working requirements of the heavy-duty wide width sisal loom,and can be flexibly controlled through electronic programs to weave different varieties of small jacquard sisal fabric products.
