一、自动封罐的作业循环与相角分布由金属薄板制成的食品罐藏容器,通称为金属罐。金属罐的端盖与罐身的牢固接合,是用二重卷边法,使两者之间形成通称为双层搭钩式的、由五层薄板料组成的紧密接缝,借助接缝之间预先涂入的弹性填料,以达到高度密封的效果。二重卷边的良好形成,是基于按预定要求制成的罐盖和罐身在正常套合情况下,通过两道具有不同轮廓曲线的特殊滚轮进行顺序性作业而实现的。这种特殊滚轮称之为封口轮,并依作业的先后分别称为第1道封口轮与第2道封口轮。其中第1道封口轮的卷
First, the automatic sealing of the operating cycle and phase angle distribution made of sheet metal food containers, commonly known as metal cans. Metal can end caps and cans of the firm, is the use of double crimping method, so that the formation of the two known as double-hook type, composed of five thin sheets of tight joints, with the help of seams Between the pre-painted elastic filler, in order to achieve a highly sealed effect. The good formation of double crimp is based on the sequential operation of two cans with different profile curves under the condition of normal nesting and can body made according to the preset requirements. This special roller is called a sealing wheel and is referred to as a first sealing wheel and a second sealing wheel, respectively, according to the operation. One of the first sealing round of the coil
