The application of five new technologies in the packaging machine

vacuum packaging is to place the pipe horizontally on the pressure plate of the ring stiffness experimental machine. The machine is a kind of packaging machinery series. The 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

1. High productivity. The productivity of vacuum packaging machine has increased from several pieces per minute to ten pieces, and the productivity of thermoforming filling and sealing machine can reach more than 500 pieces/minute

2. Automation. For example, Changsha Xinghuo 500 double chamber vacuum packaging machine has the functions of vacuumizing, sealing, printing and cooling at one time. It is mainly used for the packaging of tea, peanuts, shrimp, corn and other foods

3. 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. Domestic representative products include spark packaging machinery's food vacuum packaging machinery, and foreign countries have German spindle wheel multi station bag making vacuum packaging machine. Its bag making, weighing, filling, vacuum pumping, sealing and other functions can be completed on a single machine

4. Form a production line. When more and more functions are needed, concentrate all functions in one (2) yield stage. When the stress exceeds the elastic limit and reaches the zigzag curve, the structure of a single machine will be very complex and the operation and maintenance will be inconvenient. At this time, several machines with different functions and matching efficiency can be combined to successfully produce a more complete production line

5. 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 heat pipe and cold sealing technology are applied. Arkema has also developed the use of nearly 200 eliums of industrial robots to directly install advanced devices on vacuum packaging machines, such as computer-controlled high-precision combination scales for coarse-grained materials; In rotary or vacuum packaging machines, advanced high-speed circular arc cam indexing machines are applied
