工作原理

封边操作实际上被称为:“双重封边”(double seaming)工艺。这是因为封边由两次不同的操作完成。 罐头主体和端面被一个垂直负载夹在封边卡盘上。然后,进行第一次操作和第二次操作。

  • 第一次操作:

Seaming first operation

 

第一个操作时,滚筒卡入罐头法兰下的端面卷曲部分,这样可使这两部分形成互锁状态。

罐头封盖内侧配有一种特殊的高分子复合物,这种复合物对第二次操作很重要。

 

  • 第二次操作:

第二次操作时,滚筒压下这些处于互锁状态的金属层,将复合物挤入空隙中,完成一次真空密封。

这样,就形成了 100 %的双重密封结构。
