The vacuum packaging machine mainly refers to that the air inside the packaging bag can be automatically drawn out, and the sealing process is completed after reaching a predetermined vacuum degree. It can also be filled with nitrogen or other mixed gas, and then complete the mechanical equipment of the sealing process. Vacuum packaging machines are often used in the food industry. Products that are packaged can be protected against oxidation, mildew, insects, and moisture. They can be shelf-life-preserved and extend shelf life.
For a long time, the development trend has steadily increased. Currently, vacuum packaging machines commonly used in the market are semi-automatic vacuum devices. Simply pressing a vacuum cover automatically completes the entire process of vacuum, sealing, printing, cooling, and exhaust. In order to establish a new system of diversified, general-purpose, multi-functional and integrated packaging machinery, it is first necessary to focus on solving the major issues of composition and electromechanical integration. This is undoubtedly an important development direction in the future.
With the development and application of high-efficiency, multi-functional vacuum packaging machines and packaging materials with good barrier properties, and the combination of vacuum packaging and aeration, radiation, freezing, oxygen absorbents, ethylene absorbents and other physical and chemical methods, it will be achieved. Better storage and preservation effect.
Nowadays, the development of packaging machinery and equipment has reached a stage of comprehensive upgrading. This stage has a distinctive feature, namely the extensive use of various modern electronic technologies, microelectronics, high-precision technologies, and marginal technologies for civilian or military applications. Effectively improve the reliability, safety and other levels of packaging machinery and equipment and its production lines.
Based on the practical needs of rationally simplifying the packaging and advantageous packaging process methods, vacuum packaging machinery manufacturers need to continuously explore and accelerate the pace of their own technological innovations, especially in concert with the development of modern automatic machine tools. At present, the development trend of international vacuum packaging technology and equipment is mainly reflected in four aspects: production automation, adoption of new technologies, stand-alone multi-function and assembly production lines. The following elaborates on these four aspects.
1. Production Automation: The automation of vacuum packaging machines not only improves the production efficiency, but also has the advantages of safety and health.
2, using new technologies: In the packaging method, a large number of inflatable packaging to replace the vacuum packaging, the inflatable components, packaging materials and inflatable packaging machine three closely integrated research; control technology, more use of computer technology and micro Electronic technology; in the sealing, the application of heat pipe and cold sealing technology; advanced equipment installed directly on the vacuum packaging machine, such as loading a computer-controlled high-precision combination of coarse-grained scales; in the rotary or vacuum packaging machine, the use of advanced high-speed Circular cam indexing machines. Luo Baihui, secretary-general of the International Mould & Hardware & Plastics Industry Suppliers Association, said that the application of plastic vacuum packaging has become increasingly widespread, which has promoted the development of plastic vacuum packaging machines and also put forward higher requirements. The adoption of all these new technologies will enable vacuum. The packaging machine is more efficient and intelligent.
3, stand-alone multi-function: to achieve multi-function on a single machine, can easily expand the scope of use. The multifunctionality of the single machine is accomplished using a modular design. Through the transformation and combination of different functional modules, vacuum packaging machines suitable for different packaging materials, packaging mouths and packaging requirements are produced.
4. Assemble the production line: When more and more functions are needed, concentrating all the functions on a single machine will make the structure very complex and inconvenient for operation and maintenance. At this time, several types of machines with different functions and efficiencies can be combined into a fully functional production line to complete more complicated packaging processes.
