New development trend of the hottest plastic vacuu

New development trend of plastic vacuum packaging machine

vacuum packaging is to protect products from 3. Trial operation: after turning on the air leakage switch, it instigates the light to light up, environmental pollution and prolongs the storage life of food, which can improve the value and quality of products. Vacuum packaging technology originated in the 1940s. Since the successful application of polyester 0.36 ~ 0.40 and polyethylene plastic film in commodity packaging in 1950, vacuum packaging machines have developed rapidly. At present, the rate of high-efficiency vacuum packaging machine has developed from a few pieces per minute to dozens of pieces. The production efficiency of thermoforming filling sealing machine can reach more than 500 pieces/minute

in the field of people's life and work, a variety of plastic vacuum packaging can be found everywhere. Light, sealed, fresh-keeping, anti-corrosion, rust proof plastic vacuum packaging has been widely used in many fields, from food to medicine, knitwear, from precision product manufacturing to metal processing plants and laboratories. The increasingly wide application of plastic vacuum packaging has promoted the development of plastic vacuum packaging machine, and also put forward higher requirements for it. At present, the development trend of vacuum packaging technology and equipment in the world is mainly reflected in the following aspects

production automation: the automation of vacuum packaging machine not only improves the production efficiency, but also has the advantages of safety and health. Typ-b series rotary vacuum chamber packaging machine produced by Japanese company is a multi station packaging machine with a high degree of automation. The machine has two turntables for filling and vacuum pumping, and the filling turntable has six stations to complete bag supply, feeding, liquid injection and pre sealing, and send the packages to the vacuum pumping turntable; The vacuum turntable has 12 stations (vacuum chamber) to complete vacuum pumping, sealing, finished product output and other processes. The production efficiency can reach 40 bags/minute. It is mainly used for packaging soft canned food

single machine multi-function: realize multi-function on single machine, which can easily expand the scope of use. The multi-function of single machine is completed by modular design. Through the transformation and combination of different functional modules, vacuum packaging machines suitable for different packaging materials, packaging ports and packaging requirements are produced. Representative products include the multi station bag making vacuum packaging machine produced by Hesser factory affiliated to Bosch Company in Germany, which can integrate bag making, weighing, filling, vacuum pumping, sealing and other functions, which is convenient and fast

assembly 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 successfully combined into a more complete production line to complete more complex packaging processes. 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 all belong to this type with two backup rollers

adopt new technology: 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 sealing, heat pipe and cold sealing technology are applied; The advanced device is directly installed on the vacuum packaging machine, such as the computer-controlled high-precision combined scale for coarse particles; In rotary or vacuum packaging machines, the application of the first product publisher into high-speed circular arc cam indexing machinery. The adoption of all these new technologies makes the vacuum packaging machine more efficient and intelligent. (end)
