1. How to choose the right type of machine for customers?
The vertical packaging machine model is defined according to the maximum film width. For example, the maximum acceptable film width of the ZH-420 packaging machine is 420mm
2.知道如何计算袋的宽度
Looking at the bag type in detail, the general film width is composed of two parts, namely the bag width*2 and the sealing roller width*2. If it is gusseted, add the depth of gusset
3. What are the common optional devices for vertical packaging machines
For relatively fluffy or long-shaped materials, the bag can be slapped by the bag-beating device to allow the material to sink to the bottom of the bag better, which is convenient for roller sealing and cutting with a knife;
6. The role of the upper receiving device?
Some single materials, such as potatoes and nuts, are easy to smash the list. The upper material can prevent the material from smashing the bag; some target weights are heavier, the sealing characteristics of the list are not good, and the inner PE layer is relatively thin. When the material comes down, it is easy to smash through the horizontal seal, and the upper material can also be used;
There is also a situation where the material cannot be dropped at one time, and sometimes it will affect the sealing. Then you can use the upper receiving device to help the sealing roller to block a part of the material first to avoid the situation where the material falls into the middle of the sealing while sealing;
7.包装装置的作用是什么？
When the target weight of the material exceeds 1kg, the dragon's whiskers supporting the bag cannot stably support the two sides of the bag, which will easily cause wrinkles in the horizontal seal, which is unsightly. At this time, the bag needs to be supported to bear part of the weight; in another case, the bottom The carrier bag can be used by vibration at the moment;
8.真空装置的应用限制？
Generally for non-fluffy materials such as beans; the target weight of the material should not be too heavy, if it exceeds 400g, the effect will not be good; because when vacuuming, the bag will become smaller and the whole bag will lift. If the bag is too heavy, it will not be lifted well;
