摘　　要：为实现双物料缓急有度地输出并分装入容器,提出一种新型连杆式供送机构。由1个能生成对称、自切且带有鲍尔点的特殊连杆曲线的四连杆机构,驱动2个阀门推杆执行带停歇的直线往复运动,以控制2个阀门交替开启和闭合。四连杆机构中曲柄、连杆、摇杆及机架杆的杆长比为1:1.8371:1.8371:2,连接杆与连杆等长,夹角为109.47°。分装过程的仿真结果表明:锥形阀门在开启/闭合阶段,其运动位置对出料区域的控制可使落料量变化平稳;在1个运动周期内完成双物料的分装,提高装料的效率。研究为包装机械中的其他推送装置的设计提供新思路。In order to enable the feeding mechanism to achieve the release and subsequent sub-packaging of double materials in a natural,smooth and steady manner,a novel linkage-type feeding mechanism was proposed.Specifically,a four-bar linkage mechanism that can generate a symmetric and self-tangent coupler curve with a Ball’s point drives the two valve stems to perform a straight-line reciprocating motion with dwell,allowing the two valves to open and close alternately.In the four-bar linkage mechanism,the length ratio of the crank,coupler,rocker and frame is 1:1.8371:1.8371:2,and the length of the connecting rod is equal to that of the coupler,with an angle of 109.47°.The simulation result of the sub-packaging process shows that during the opening/closing phase of the cone-shaped valve,its movement position controls the discharge area,achieving a smooth change in the particle flow rate.Moreover,due to the sub-packaging of double materials within a movement cycle of the mechanism,the loading efficiency can be improved.The present study also provides new insights into the design of other feeding mechanisms in packaging equipment.
