Innovation in the application of international vacuum packaging machine technology

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 developed from several pieces per minute to ten pieces. When we summarize more methods, the productivity of type 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. in Japan is a multi station packaging machine with a high degree of automation. The machine has two turntables, filling and vacuumizing. In fact, all innovations and research and development can achieve the desired effect. The filling turntable has six stations to complete bag supply, feeding, liquid injection and pre sealing until the package is transferred to the vacuumizing 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/min. it accelerates the quality reform, effectiveness reform and power reform of the new material industry, which is mainly used for packaging soft cans

single machine multi-function

realize multi-function on a single machine, which 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, but the operation of the machine often requires different 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, centralizing all functions on three single machines 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 successfully to form a more complete production line. For example, the vacuum packaging production line for fresh fish developed by French cracecryoya and ISTM, and the textile vacuum packaging system developed by Swedish Shuhong International Co., Ltd. and Swedish Textile Research Institute

adopt relevant new technologies

in terms of packaging methods, a large number of inflatable packaging are 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; Applying heat pipe and cold sealing technology in sealing, advanced devices can also be directly installed on vacuum packaging machines, such as computer-controlled high-precision combined scales for coarse materials; In rotary or vacuum packaging machines, advanced high-speed circular arc cam indexing machines are applied
