Over 30 years ago, the output value of the vacuum packaging machine industry in China was only tens of millions of yuan, and there were only 100 types of vacuum packaging machine products. However, at present, the output value of the vacuum packaging machine industry in China has reached 80 billion, and is still growing at an annual rate of over 10%. Product types and series are also more robust and diverse, with more than 4,000 varieties. Automated multifunctionality is the future trend of vacuum packaging machinery. The dependence of equipment on imports is still a root cause that has not been resolved. As we all know, German packaging machinery is world-class in terms of measurement, manufacturing, and technical capabilities. The country's production of beer, beverage filling complete sets of equipment, production speed, high degree of automation and reliability. Of the packaging machinery produced in Italy, 40% are food packaging machines, such as candy packaging machines, tea packaging machines, and filling machines. The product features elegant appearance, excellent performance, and low price. Although Japan's food packaging machinery is mainly based on small and medium-sized single machines, it is small in size, high in precision, easy to install, easy to handle, and highly automated. Relative to the foreign advanced equipment for improving seniors, domestically produced food and packaging machinery is a bit "failure". Although there are price advantages, for some large-scale enterprises, the quality of products is still the number one, domestic equipment. Obviously, the company's needs cannot be met. Under comparison, companies would rather spend more money to purchase foreign advanced equipment. As the saying goes, “If a worker wants to do something good, he must first sharpen his tools.†For food and packaging machinery manufacturing companies, promoting their own technical level and producing high-quality equipment are the hard truths for companies to become bigger and stronger. In order to improve the current status of relying on foreign equipment too much. Vacuum packaging in 2015, after all, is still just on the road. Sometimes the vacuum packaging machine may cause poor suction if it causes some malfunctions or improper operation, and it is worth paying attention to. When the vacuum packaging machine is used for shrink packaging of the product, the air in the packaging film must be evacuated to achieve a vacuum inside the packaged product, which is beneficial to the long-term preservation of the product. The vacuum packaging machine uses vacuum packaging film to vacuum pack the product, so the quality control of the vacuum packaging film is particularly critical. The quality of the vacuum packaging film must have a certain thickness and a certain thickness. During the preservation process before use and the packaging process in use, the vacuum packaging film must be well protected from air leakage. The vacuum packaging machine avoids the problem of being unvacuum. The seal control time cannot be closed prematurely to avoid the presence of residual air in the packaging film. The quality of the seal must be guaranteed, and the seal must be fully closed to avoid the occurrence of air leakage and affect the degree of vacuum in the vacuum packaging film. The core part of the vacuum packaging machine is a vacuum pump. It takes a long time to work. The dust, dirt, etc. can easily enter the vacuum pump, causing the packaged product to get dust or dirt. The vacuum pump must be changed at this time. Frequent oil changes can enhance the vacuum pumping machine. Also pay attention to the protection of the internal pressure air bag of the vacuum packaging machine to prevent it from cracking and not achieve a good pumping effect. Ensure that the vacuum packaging machine has sufficient time for pumping the product, so as to ensure that the air inside the packaging film can be fully evacuated and the internal vacuum degree can be guaranteed. In-depth understanding of the vacuum packaging machine The package must not only complete the vacuuming and inflating processes in the vacuum chamber, but more importantly it should be heat-sealed and sealed before the vacuum chamber is deflated to ensure that the packaged items are in a closed vacuum or vacuum after vacuuming. In an airless environment. The double chamber vacuum packaging machine produced by our company adopts this principle. Because the packaging process of the vacuum packaging machine is completed in a vacuum chamber, it is not difficult to conduct vacuuming for a closed and independent vacuum chamber. It is only necessary to connect the airtight connector of the closed vacuum chamber with the vacuum system. Similarly, the inflation and deflation of the vacuum packaging machine is also very easy to implement, as long as the gas system is switched by the vacuum system. After years of social development and evolution, vacuum packaging machine equipment has been greatly improved in function and performance, providing good technical conditions for the completion of outstanding packaging. While enriching the variety of product packaging, it also found business opportunities for the development of production companies. It has become a kind of vacuum packaging machinery and equipment that is indispensable in the pharmaceutical industry and more industries. The TYP-B series rotary vacuum chamber packaging machine produced by a Japanese company has a multi-station with a relatively high degree of automation. The machine has two turrets for filling and evacuation. The filling turret has six stations. The bags are filled, fed, filled and pre-sealed until the packages are sent to the vacuum turret. The vacuum rotary table has 12 stations, that is, 12 vacuum chambers. Vacuum pumping and sealing are completed until the output of the finished product. The production efficiency is up to 40 bags/min. It is mainly used for packaging soft canned foods. It is necessary to ensure that the vacuum packaging machine has sufficient time for pumping the product to ensure that the air inside the packaging film can be fully evacuated and the internal vacuum degree can be guaranteed. Because the packaging process of the vacuum packaging machine is completed in a vacuum chamber, it is not difficult to conduct vacuuming for a closed and independent vacuum chamber. It is only necessary to connect the airtight connector of the closed vacuum chamber with the vacuum system. Similarly, the inflation and deflation of the vacuum packaging machine is also very easy to implement, as long as the gas system is switched by the vacuum system.
