The assembly line integrated production packaging is applied to the filling (filling), sealing machine, and coding of (bagged, bottled) products in industries such as food, medicine, daily chemicals, hardware, lighting, and furniture

China's packaging machinery started relatively late, starting in the 1970s when the Beijing Commercial Machinery Research Institute studied Japan's packaging machinery. After more than 20 years of development, China's packaging machinery has become one of the top ten industries in the mechanical industry, providing strong support for the rapid development of China's packaging industry. Some packaging machinery has filled the domestic gap and can basically meet the needs of the domestic market. Some products are also exported. The import volume and total output value of packaging machinery in China are roughly equivalent, which is far from developed countries.

As for the sales packaging of food, there are two main types of packaging techniques commonly used and basic nowadays, namely filling and wrapping. The filling method is almost applicable to all materials and various packaging containers. Specifically, for liquids, powders, and loose particles with good flowability, the packaging process can be completed mainly by relying on their own gravity, supplemented by certain mechanical actions if necessary. For semi fluid or large single or composite components with strong viscosity, corresponding mandatory measures such as squeezing, pushing, and picking up and placing are required. As for the wrapping method, it is different from this. It is mainly suitable for single or composite parts with a regular appearance, sufficient rigidity, and a requirement for tight packaging. Flexible plastic and its composite materials (some with additional lightweight pallets and lining plates) are often used for wrapping with the help of mechanical action.

With the continuous improvement of people's living standards, the demand for various convenient foods has also greatly increased, which has further driven the rapid development of China's food packaging industry. Vacuum packing machine is one of the fast developing packaging machines, which has broad prospects for development. There are many kinds of Vacuum packing machines. Now let's introduce Vacuum packing machines.

To create the maximum benefits for oneself within the specified time, it is necessary to ensure that one's food packaging production line operates well and there are no errors during the production process. This will minimize the occurrence of errors and the impact of malfunctions, and only then can the enterprise obtain the maximum benefits. The level of automation is constantly improving in the manufacturing industry, and its application scope is expanding.

Vacuum packing technology originated in the 1940s. Since the successful application of polyester and polyethylene plastic films in commodity packaging in 1950, the Vacuum packing machine has developed rapidly, and its technological development trend is mainly reflected in five aspects: high productivity, automation, single machine multi-function, production line formation, and the adoption of related new technologies.
1. High productivity. The productivity of Vacuum packing machine has developed from several pieces per minute to 10 pieces. The productivity of Thermoforming filling sealing machine can reach more than 500 pieces/minute.
2. Automation. The full-automatic Vacuum packing 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 multifunctional. Implementing multifunctional functions on a single machine can easily expand the scope of use. To achieve single machine multifunction, modular design must be adopted. Through the transformation and combination of functional modules, different types of vacuum packaging machines suitable for different packaging materials, items, and requirements can be developed.
4. Form a production line. When more and more functions are needed, concentrating all functions on a single machine can make the structure very complex and operation and maintenance inconvenient. In this case, several machines with different functions and matching efficiency can be combined successfully to achieve a more complete production line.
5. Adopting relevant new technologies. In terms of packaging methods, inflatable packaging is widely used to replace Vacuum packing, and the research on inflatable components, packaging materials and inflatable packaging machines is closely combined; In terms of control technology, more application of computer technology and microelectronics technology; In terms of sealing, heat pipe and cold sealing technology can be applied, and advanced devices can also be directly installed on Vacuum packing machines, such as computer controlled high-precision combination scales for coarse materials; On rotary or Vacuum packing machines, advanced high-speed circular arc cam indexing machines are used.

The sealing machine is the best process for completing product packaging, so the daily care and protection of the sealing machine cannot be ignored.

Unified size requirements for easy to pull bottles, bottle mats, and bottle caps

The high-end form of filling machine development is the use of automatic filling machines, which not only enables complete automation of filling machines, but also precise filling methods that reduce costs, improve efficiency, and reduce consumption, which is a win-win situation. Of course, ordinary forms of filling machines are still being used in many enterprises, and they can also complete corresponding filling tasks with an advantage in price. It seems that some people want to say, so what is the purpose of developing automatic filling machines? In fact, they have overlooked an important issue of enterprise development. We are well aware that the market is constantly changing.
