China's packaging machinery started late. After more than 20 years of development, China's packaging machinery has become one of the top ten industries in the machinery industry, providing a strong guarantee for the rapid development of China's packaging industry. Some packaging machinery has filled the domestic gap and has been able to basically To meet the needs of the domestic market, some products are also exported. Moreover, China has made great progress since its accession to the WTO. The level of packaging machinery has risen very rapidly, and the gap with the world's advanced level has gradually narrowed. As China becomes more open, China's packaging machinery will further open up the international market. However, at present, the export value of China's packaging machinery is still less than 5% of the total output value, but the import value is almost equal to the total output value, which is far from the developed countries.
This situation is mainly due to the "congenital deficiency" of China's packaging machinery industry. China started relatively late, with weak technical strength, and did not invest enough funds to support packaging technology and equipment research and development. Secondly, the product is repetitive, limited to a low level of technology, and most of the circulation in the market is a product with low precision and simple manufacturing process. Most of the high-capacity packaging equipment still relies on foreign imports to meet domestic demand. After that, there is a shortage of professional packaging technology talents, which is not conducive to the improvement of the existing equipment, everyone is just busy production and sales. Rarely calm down to research and development.
In the face of this situation, which direction should China's packaging machinery develop? The industry believes that from the future development trend, packaging machinery will cooperate with industrial automation, promote the overall level of packaging equipment, develop multi-functional, beneficial, low-consumption packaging equipment to achieve mechanical and electrical integration of packaging machinery. Such a trend is still a huge challenge for today's packaging machinery.
First, production automation: the automation of vacuum packaging machine not only improves production efficiency, but also has the advantages of safety and hygiene. The typ-b series rotary vacuum chamber packaging machine produced by the Japanese company is a multi-station packaging machine with a high degree of automation. The machine has two turntables for filling and vacuuming, and there are 6 stations for filling the turntable. The bag is filled, the material is fed, the liquid is pre-sealed, and the package is sent to the vacuum rotary table. The vacuum rotary table has 12 stations (vacuum Room), the process of vacuuming and sealing, finished product output, etc., the production efficiency can reach 40 bags / min, mainly used for packaging soft canned foods.
Second, the use of new technology: in the packaging method, a large number of inflatable packaging to replace the vacuum packaging, the combination of inflatable components, packaging materials and inflatable packaging machine research; in the control technology, more application of computer technology and micro Electronic technology; in the aspect of sealing, application of heat pipe and cold sealing technology; installation of advanced equipment directly on vacuum packaging machine, such as computer-controlled coarse-grain high-precision combination scale; on rotating or vacuum packaging machine, applying advanced high-speed Circular surface cam indexing machine. The adoption of all these new technologies makes the vacuum packaging machine more intelligent.
Third, single machine multi-function: multi-function on a single machine, can easily expand the scope of use. The versatility of the stand-alone unit is done in 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. The representative products are multi-station bag vacuum packaging machine produced by Hesser Factory of Bosch Company of Germany. It can integrate bag, weigh, fill, vacuum, seal and other functions in one, convenient and fast.
Fourth, the assembly line: When more and more functions are needed, concentrating all the functions on a single machine will make the structure very complicated and the operation and maintenance will be inconvenient. At this time, several machines with different functions and matching efficiency can be combined into a more complete production line to complete more complicated packaging processes. For example, the fresh fish vacuum packaging production line developed by France's cracecryoya and ism company, the textile vacuum packaging system developed by Swedish Shuhong International Co., Ltd. and the Swedish Textile Research Institute belong to this type.

Development status and trend of vacuum packaging machine
[ppzhan abstract] China's packaging machine started late, due to technical backwardness, the current equipment still depends on imports. To change this situation, the main thing is to start with basic technology and solve the problem fundamentally.
