新型Z轴全动绗缝刺绣机的设计

Research on quilting machine of Z-axis full-motion

针对传统的绗绣机X轴传动机构惯量大而造成的刺绣速度不高、易产生振动而影响绣品质量的问题,提出了将X轴传动机构集成到Z轴的方案。新型传动方案使得绗绣机整机结构紧凑、合理,与传统绗绣机相比较,传动部件总质量减少了50%,大大降低了运动惯量,减小了机器振动,刺绣速度可提高25%以上。与此同时,还对绗绣机多轴联动的同步驱动精度、罗拉及控制软件的优化等关键技术问题进行了深入研究,以此来进一步提高绗绣速度和质量。所研制产品经试验和实际使用表明,其主要性能指标先进。

Aiming at the disadvantages of low-speed quilting and vibration,which caused by the big inertia of the X-axis drive mechanism in the traditional quilting machine,affects the quality of embroidery,an innovative solution was presented.It integrates the X-axis drive mechanism to the Z-axis.The improved drive scheme makes the composition of quilting machine more compact and reasonable.Compared with the traditional quilting machine,the total mass of X-axis mechanism decreases 50%.It reduces the vibration and improves the embroidery speed at least 25%.Meanwhile,the key problems,which are the synchronous drive precision and the optimization of the roller and control software,were studied to enhance the quilting speed and embroidery quality.The developed quilting machine has a good performance,which is demonstrated by the results of a large number of experiments and applications.
