摘要: 针对地毯簇绒机成圈运动的时间配合关系与簇绒工艺要求之间不匹配会影响地毯质量的问题,首先提出地毯簇绒过程中时间配合的分析要点,以指导成圈机构的结构设计和相位关系的确定。通过Adams运动分析,获得传统成圈运动机构的时间配合关系,指出该时间配合关系的不足之处,由此提出2种基于非简谐运动方式的成圈运动机构的时间配合方法,并进行了相应的执行机构设计。经过Adams运动分析验证该成圈运动机构可较好地满足地毯簇绒工艺要求。

Abstract: The mismatch between the time coordination of loop-forming motion and the tufting process can cause problems with unevenness of the tuft pile surface and so results in lower quality carpets.In view of problems above,the key point of the time coordination in the carpet tufting process is proposed firstly,that is used to guide the mechanical design and the phase adjustment of the loop-forming device of the tufting machine.Through Adams motion simulation,specific analysis is focused on the motion time coordination of the conventional loop-forming device which is considered with a shortage in matching the tufting process.Consequently,two methods of the motion time coordination based on non-simple harmonic motion(n-SHM) are proposed to the loop-forming device,which is proved in Adams to well conform to the requirements of the carpet tufting process.And finally the relevant mechanisms are schemed to produce the n-SHM actions of the tufting needle and the looper.
