摘　　要：针对目前小剂量灌装机的人工上料存在效率低下、安全卫生不达标等问题,课题组提出一种基于四杆机构的理瓶机构方案。运用解析法对理料机构进行了结构分析,针对四杆机构特性创建平面简图,采用解析法针对其运行过程中的运动学理论进行分析计算;采用ADAMS软件对目标机构进行建模与仿真分析,并以四杆机构曲柄、连杆、摇杆长度为设计变量,以压力角最小为目标,各杆件之间相互关系为约束条件,进行优化设计得到最优解,使压力角减少了19.6%。优化设计有效解决了原灌装机全自动理料效率低的问题,并通过ADAMS软件对目标机构的优化设计进一步提升了传动效率。Aiming at the problems of low efficiency and unsatisfied safety and health in manual feeding of small dose filling machine at present,an unscramble bottle body scheme based on four-bar linkage mechanism was put forward according to the packing materials technical requirements.The structure of material handling mechanism is analyzed by analytic method.In view of the characteristic of four bar linkage to create graphic diagram,analytic method was adopted to analyze the kinematics theory for its operation process calculation.ADAMS software modeling and simulation analysis were carried out on the goal mechanism,with four bar linkage crank connecting rod rocker arm length as design variables,the minimum pressure angle as the goal,the relationship between bars as constraint conditions,optimized design to get the optimal solution,reducing the pressure angle by 19.6%.The optimization design effectively solves the problem of low efficiency of the original filling machine automatic bedding material process,further improves the transmission efficiency through the optimization design of target mechanism by ADAMS software.
