With the acceleration of people's daily work pace, the richness of nutrition and health food, and the awareness of environmental protection, many new requirements will be imposed on food and its packaging in the future. This includes the development of new technologies and new products such as vacuum packaging, vacuum inflatable packaging and aseptic packaging to integrate with frozen packaging. Focusing on the present and the future, we can confirm that the following three types of packaging machines are excellent models for food sales and packaging, and can be called a leading model with a long history and strong vitality, namely vertical bags ( Box) Forming filling and sealing machine, horizontal bag (box) forming filling and sealing machine, horizontal seam wrapping machine.
According to the analysis of group technical ideas, the commonality and similarity among the three are more conducive to unified development, and each has special differences, which should be selected according to local conditions. After a comprehensive comparison, the main features are as follows:
Packing objects - Matching 3 models is almost all-inclusive (usually except gas and liquid), but the third limitation.
Packaging materials - mainly in the form of roll-type composite film, in some cases the second can be placed inside the straw, the third can be placed inside the rib and other accessories.
Packing form - the second type of pattern is more, such as three-side sealing bag, four-side sealing bag, double-bag, stand-up bag, brick box, roof box, etc.; * the second is the second, usually the third Pillow-shaped bags are mainly used, and some can be made into cylindrical bags, four-side sealed bags, and the like. Packing size - * bag width zui as small as 10 mm, bag length can be adjusted steplessly within the limited range; the latter two bag width and bag length can be steplessly adjusted within a limited range, of which the third The bag can be more than half a meter long.
Type of sealing - the second type is new, such as the upper end of the tearing or tearing line, the combination of the inset box, the screw cap in different parts, etc.; the other two The model looks monotonous.
Transfer motion - both continuous motion and step motion. Structure combination - fully reflects the modular knot, especially the second horizontal layout is more convenient to configure functional modules (such as vacuuming, nitrogen filling), plus high degree of mechatronics, making diversity, versatility, multi-functional integration The nature is greatly enhanced, forming a series of products.
