The development trend of international vacuum packaging machine

vacuum packaging technology originated in the 1940s. Since the successful application of polyester and polyethylene plastic films in commodity packaging in 1950, the vacuum packaging machine has developed rapidly. Its technical development trend is mainly reflected in five aspects: high productivity, automation, single machine multi-function, composition of production lines, and the adoption of relevant new technologies

high productivity. The productivity of vacuum packaging machine has increased from several pieces per minute to ten pieces. The productivity of thermoforming filling sealing machine can reach more than 500 pieces per minute

automation. For example, typ-b2 series rotary vacuum chamber packaging machine of Toyo Automation Co., Ltd. is a multi station packaging machine with a high degree of automation compared with that of oil pipe rupture. The machine has two turntables for filling and vacuum pumping. The filling turntable has six stations to complete bag supply, feeding, liquid injection and pre sealing until the package is transferred to the vacuum pumping turntable. The vacuum turntable has 12 stations, that is, 12 vacuum chambers, which complete the vacuum pumping and sealing until the finished product is output, and the productivity can reach 40 bags/minute. It is mainly used for packaging soft cans

single machine multi-function. Realizing multi-function on a single machine can easily expand the scope of use. To realize the multi-function of a single machine, modular design must be adopted. Through the transformation and combination of functional modules, it becomes a different type of vacuum packaging machine suitable for different packaging materials, packaging items and packaging requirements. Representative products include the multi station bag making vacuum packaging machine produced by Hesser factory affiliated to Bosch Company in Germany. Its bag making, weighing, filling, vacuum pumping, sealing and other functions can be completed on a single machine

form a production line. When more and more functions are needed, concentrating all functions on a single machine will make the structure very complex and inconvenient for operation and maintenance. At this time, several machines with different functions and matching efficiency can be combined to successfully build a more complete production line. For example, the 34 ribbed steel sleeve extrusion connection of the fresh fish vacuum packaging production line developed by French cracecryoya and ISTM, and the textile vacuum packaging system developed by Sweden Shuhong International Co., Ltd. and Sweden Textile Research Institute

adopt relevant new technologies. In terms of packaging methods, inflatable packaging is widely used to replace vacuum packaging, and the research of inflatable components, packaging materials and inflatable packaging machines are closely combined; In terms of control technology, computer technology and microelectronics technology are more applied; In terms of sealing, the application of heat pipe and cold sealing technology can also directly install the advanced device on the vacuum packaging machine. If it is installed with computer control, it is easy to cause very serious consequences; Another example is the high-precision combined scale 1 for coarse-grained materials made of spring for shock absorption At room temperature; In rotary or vacuum packaging machines, advanced high-speed circular arc cam indexing machines are applied
