1. How to choose the right type of machine for customers?
Vertical packaging machine model is defined according to the largest film width
2. Know the bag width how to calculate the film width
depends on the bag type. Generally, the film width consists of two parts, namely the bag width*2 and the sealing roller width*2. If it is gusseted angle, add gusset depth
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 tearing device / upper receiving hopper vibration device / thermal transfer coding machine / dust removal device Waiting/bagging device/vacuum
4. What are the functions of even the package? What are the shortcomings?
5. What is the role of the bag-slap device?
For relatively fluffy or long-striped materials, the bag can be slapped by the bag-beating device, so that the material can sink to the bottom of the bag better, which is convenient for roller sealing and cutting with a knife;
6. What is the function 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 relatively heavy, 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 where the material cannot be dropped at one time, and sometimes it will affect the sealing. Then you can use an upper receiving device to first help the sealing roller to block a part of the material to avoid the material falling into the middle of the sealing while sealing;
7. What is the role of the bag holding device?
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 lowered to bear part of the weight; in another case, the bottom The carrier bag can be used by vibration at the moment;
8. Application limitation 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 be lifted well;
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; it needs fast contact, fast sealing, and fast withdrawal of the sealing roller; the sealing form is generally a line;
10. How many cut shapes does the vertical packaging machine have?
jagged, flat mouth
