四头直线式旋盖机的设计

Design of Four Heads Linear-capping Machine

目的设计一种适合频繁更换桶形的直线式旋盖机。方法针对不同桶形的长宽高和不同的桶盖,四头直线式旋盖机设计有相应的调节机构和快速更换机构,并阐述其结构组成、工作原理及调节机构的设计。其中水平调节机构利用螺旋机构原理,将2根丝杠的旋转运动转变成4个旋盖头的平移运动,且2根丝杠由特定传动比的齿轮联动,转动调节手轮即可实现4个旋盖头等间距调节;该设备还为旋盖头设计快速更换机构。结果四头直线式旋盖机结构简单,成本低,更换桶形时调整方便,大大提高了生产效率。结论四头直线式旋盖机在包装机械领域具有更大的实用性和推广性。

This study was aimed to design a linear-capping machine suitable for replacing the bottles frequently. Four heads linear-capping machine was designed with adjusting mechanism and quick replacing mechanism to match bottles with different length, width, high, and caps. Its structure, working principle and the design of adjusting mechanism were also illustrated. Among them, the level adjusting mechanism converted two screw＇s rotation movement into four capping heads＇ linear motion, utilizing the principle of the screw mechanism. And the two screws could rotate in special transmission ratio in accordance with the gear ratio. So equal spacing adjustment of four capping heads could be achieved by simply turning the handwheel. And quick replacing mechanism was designed for its capping heads. Four heads linear-capping machine had simple structure, low cost, and convenient adjustment when changing bottle shape, which largely increased the productivity.Four heads linear-capping machine could have more practicability and popularization in the field of packaging machinery.
