Basic understanding of vertical packaging machine.

08 Apr 2021

1. How to choose the right type of vertical packaging 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. Know the bag width of the vertical packaging machine, how to calculate its film width?

Looking at the bag type in detail, the general film width is composed of two parts, 2 bag widths and 2 sealing roll widths. If it is gusseted angle, add the depth of gusseted angle additionally.

3. What are the common optional devices for vertical packaging machines?

Gusset device / punching device / upper receiving device / lower bag device / nitrogen filling device / exhaust device / continuous bag device / easy tear device / upper receiving hopper vibration device / thermal transfer coding machine / dust removal device Waiting/bagging device/vacuuming

5. The function of the bag shooting device:

For relatively fluffy or long-shaped materials, the bag patting device can make the material sink to the bottom of the bag better, which is convenient for roller sealing and cutting with a knife.

6. The function of the upper receiving device:

Some single materials are heavier, such as potatoes and nuts, which 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 another situation: 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 part of the material first to avoid the situation that the material falls into the middle of the sealing while sealing .

7. The function of the lower bag holding device:

When the target weight of the material exceeds 1kg, the dragon whiskers supporting the bag cannot stably support both sides of the bag, which will easily cause wrinkles in the horizontal seal, which is unsightly. At this time, the bag needs to be lowered to bear part of the weight; in another case, the bottom The carrier bag can be used by vibrating at the moment;

8. Application limitations of vacuum device:

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 work well. The promotion.

9. What are the characteristics of PE film sealing device:

PE film is easy to melt, the temperature should not be too high, the film will melt as soon as the sealing roller touches the film; therefore, quick contact, fast sealing, and fast withdrawal of the sealing roller are required; the sealing form is generally a line.

10. The vertical packaging machine has several cutting shapes: such as serrated, flat mouth, etc.
