电动地毯织枪机构分析

Analysis on mechanical structure of electric tufting gun

为掌握电动地毯织枪的使用方法和调试方式,提高织枪的织造质量,以常规电动地毯织枪为研究对象,研究了织枪机械结构特点和工作原理,根据建立的数学模型用Mat Lab-SIMULINK对织枪的主要运动机构双曲柄滑块机构进行运动学仿真和时序分析,明确了解针刀的配合要求,获得了机构的运动规律。结果表明,压布板在钢针尖和剪刀尖运动曲线交叉点位置之下,可以满足织枪的工作要求。依据运动学方程得出不同绒高对应的可调节杆长最优值,并得出可调节杆长的调节趋势,所得的理论数据可用于对织枪进行辅助调试,减少了调试时间。

In order to master the using method and debugging methods of the electric tufting gun and improve the quality of tufting, a type of the electric tufting gun was chosen as the research object. First, the mechanical structure characteristics and working principles of the electric tufting gun are introduced. Then, in order to be familiar with the coordination requirements between needle and scissor, MatLab-Simulink is used for the kinematics simulation and time series analysis of two-slider-crank mechanism. Finally the results of kinematics equation can be used for variable parameter adjustment, which is convenient for tufting gun debugging to satisfy the requirement of weaving the corresponding pile height. The theoretical data can be used to debug the tufting gun and reduce the debugging time.
