贴标机在包装工业中发挥着越来越重要的作用。市场上的贴标机种类很多，但它们是密不可分的。贴标机贴标方法主要有摩擦、吹、吸。三个方法。这三种贴标方法也各有优缺点。
1.搓贴法的工作原理:当贴标机标签正面边缘贴在产品上时，产品会立即将标签带走。这种方法的优点是贴标速度快，贴标精度取决于产品通过贴标机的速度和贴标分配的速度。如果两种速度相同，贴标精度高。否则会影响贴标机的精度。的影响。
2. The working principle of the suction method: When the label paper of the labeling machine leaves the conveyor belt, it is sucked onto the vacuum pad, which is connected to the end of a mechanical device. When the mechanical device stretches until the label is in contact with the product, it shrinks back and the label is attached to the product. The advantage of this method is that it has high accuracy and is suitable for the labeling process of highly difficult packaging products; the disadvantage is that the labeling speed is slow and the labeling quality is not good.
3.吹气法的工作原理:是在吸气法的基础上改进的。不同之处在于，真空垫的表面是固定的，标签被固定并定位在一个“真空网格”上。“真空网格”是一个平面，上面有数百个小孔。小孔被用来维持“空气喷射”的形成。从这些“空气喷射”中，一股压缩空气被吹出，压力非常大，移动了真空网格上的标签，让它附着在产品上。该方法的优点是具有较高的准确性和可靠性;缺点是过程复杂。
The comparison of the three labeling methods found that the rubbing method can greatly improve the working speed of the labeling machine, which is in line with the development trend of pursuing high efficiency.
