一种PLC控制L型大板块包装机的设计

Design of Large L-shaped Plate Packaging Machine Based on PLC

目的针对大板块包膜的特殊需求,设计一种由PLC控制的L型大板块自动包装机。方法通过分析大板块包膜背封、插角和点胶侧封动作的功能要求,采用Pro/E软件分别建立了取膜、背封、四角插封和点胶侧封等机构的三维模型,并对其关键的背封和四角插封机构进行了优化,完成了大板块自动化包装机的设计。结果该包装机能够对2种不同尺寸的大型板块进行完整包膜。结论采用四角插封方式,解决了大板块自动化包膜四角整齐包装的难题,提高了大板块包装机的工作效率和包膜效果。该机能够对不同尺寸的板块进行包膜,且更换组件更简便,具有广阔的应用前景。

A large L-shaped plate automatic packaging machine based on PLC was designed according to the special needs of large plates envelope. The functions and requirements of movements for back closure, angle fold and dispensing side seal were analyzed, three-dimensional models of taking the film, back closure, square plug sealing and dispensing were set up by Pro/E software, and then the key back closure and corners seal plug seal mechanisms were optimized to complete the design of large plates automated packaging machine. The packaging machine could realize complete envelope for large sections of two different sizes. The machine solved the corners neatly packed puzzle of big plate automation envelope with corners plug seal manner, and in addition improved the efficiency and envelope effect of big plate packaging machine. The plates of different size could be coated by the machine and it was easier for replacing components, it showed that the machine had a good application prospect and high practicability.
