摘　　要：传统的往复式横封机构有凸轮式和气缸式。针对凸轮式横封机构凸轮轮廓不合理容易引起震动和噪声,气缸式横封机构速度改变时存在较大冲击以及气缸密封性等问题,课题组提出了一种新型粉末包装机往复式横封机构。课题组采用解析法与三维软件相结合的方法对该机构进行研究,建立了粉末包装机往复式横封机构的数学模型,对横封机构的执行末端横封头进行了受力分析和运动学分析。通过SolidWorks软件进行三维建模,并运用SolidWorks Motion对横封机构的横封头进行了运动学模拟仿真。结果表明该横封机构具有平稳、噪声小等优点,可方便地进行调速,适应多种包装袋长的横封要求。The traditional reciprocating transverse seal mechanism has cam and cylinder type. Cam type suffered vibration and noise caused by unreasonable cam profile,cylinder type was largely impacted and easily caused sealing problems when the cylinder speed was changed. A new type of powder packaging machine for reciprocating transverse sealing mechanism was presented. By combination of the analytical method and the three-dimensional software,the research on the agency was carried out. The mathematical model of the reciprocating transverse sealing mechanism of the powder packaging machine was established to carry out the stress analysis and kinematic analysis of the transverse head of the transverse sealing mechanism. The three-dimensional modeling through Solid Works software was established to simulate the kinematics of cross-head. The results show that the transverse seal mechanism has the advantages of smooth,lower noise,and it can be easily adjusted the speed to meet the requirements of transverse seals for variety length of bags.
