Development prospect forecast of packaging machine

most of China’s food packaging enterprises are small in scale, “small and complete” is one of their main characteristics. At the same time, there are repeated production of mechanical products with low cost, backward process level and easy to manufacture regardless of the development requirements of the industry. About 1 /4 of the enterprises in the industry have low-level repeated production. This is a great waste of resources, causing confusion in the packaging machinery market and hindering the development of the industry
the annual output value of most enterprises ranges from several million yuan to 10 million yuan, and there are many enterprises less than 1 million yuan. Nearly 15% of enterprises change production or close down every year, but another 15% of enterprises join the industry, which is extremely unstable, which hinders the stability of the development of the industry
with the continuous development of science and technology and the emergence of various food and aquatic products, new requirements are put forward for food packaging technology and equipment. The competition of food packaging machinery is becoming increasingly fierce. In the future, food packaging machinery will cooperate with industrial automation to improve the overall level of packaging equipment and develop food packaging equipment with multi-function, high efficiency and low consumption. Realize the electromechanical integration of food packaging machinery
the traditional packaging machinery mostly adopts mechanical control, such as cam distribution shaft, and then there are photoelectric control, pneumatic control and other control forms. However, with the increasing improvement of food processing technology and the increasing requirements for packaging parameters, the original control system has been difficult to meet the needs of development. New technology should be adopted to change the appearance of food packaging machinery. Today’s food packaging machinery is a mechanical and electronic equipment integrating machinery, electricity, gas, light and magnetism. In the design, we should focus on improving the automation of packaging machinery, combine the R & D of packaging machinery with computers, and realize mechatronics control
the essence of Mechatronics is to organically combine machinery, electronics, information, detection and other related technologies from a system point of view and using the principle of process control to achieve overall optimization
generally speaking, it introduces microcomputer technology into packaging machinery, applies mechatronics technology, develops intelligent packaging technology, and combines it into a full-automatic packaging system for production according to the requirements of product automatic packaging process. The detection and control of production process and fault diagnosis and troubleshooting will realize comprehensive automation and realize high-speed, high-quality, low consumption and safe production. It can be used for accurate measurement, high-speed filling and automatic control of packaging process of aquatic processed food, which will greatly simplify the packaging mechanical structure and improve the quality of packaging products. For example, the most common plastic bag sealing machine, its sealing quality is related to packaging materials, heat sealing temperature and running speed. If the material (material and thickness) changes, the temperature and speed will also change, but the change is difficult to grasp. If microcomputer control is adopted, the best parameters of sealing temperature and speed of various packaging materials are matched and input into microcomputer memory, and then equipped with necessary sensors to form an automatic tracking system. In this way, no matter which process parameter changes, the best sealing quality can be guaranteed. Adopt new technology and establish a new system of automatic, diversified and multi-functional integrated packaging machinery
the technical development trend of food packaging machinery is mainly reflected in high productivity, automation, single machine multi-function, multi-functional production line and new technology. Such as: 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; Several machines with different functions and matching efficiency can be combined into a production line with complete functions, such as the fresh fish vacuum packaging production line developed by France and ISTM
apply heat pipe and cold sealing technology in sealing. In addition, with the progress of packaging research from single technology to combination with processing, the field of packaging technology should be extended to the field of processing, and food processing and packaging equipment integrating packaging and processing should be developed. Adapt to the requirements of the international market and develop and design green packaging machinery
after China’s entry into WTO, the competition in the international packaging machinery industry has become increasingly fierce. Foreign green trade barriers put forward higher requirements for the food packaging machinery industry. Therefore, the traditional design and development mode of packaging machinery must be changed, In the design stage, the “green characteristics” such as no or minimum impact on the environment, low resource consumption and easy recycling in the whole life cycle of packaging machinery (design, processing and manufacturing, assembly, use, maintenance and waste post-treatment and disposal process) are considered to enhance the core competitiveness of China’s packaging machinery
the catalogue of key raw materials including printing ink and their suppliers shall be filed to supervise and control the batch production of food packaging /container products, so that consumers can buy products that ensure safety and security. Because the food and drugs that millions of consumers want to eat every day must use soft plastic packaging materials that can not only protect the contents from virus and bacteria pollution, but also require the soft plastic packaging materials to comply with the safety and health regulations and avoid the packaging materials from polluting the packaged food and drugs, it is urgent to ensure the health and safety of food packaging
the development trend of packaging machines in the 21st century
vacuum packaging technology originated in the 1940s. Since the successful application of polyester and polyethylene plastic films in commodity packaging in 1950, 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 line and adoption of relevant new technologies. 1. High productivity. The productivity of vacuum packaging machine has increased from several pieces per minute to ten pieces. The productivity of thermoforming filling sealing machine can reach more than 500 pieces /min. 2. Automation. The automatic vacuum packaging machine has the functions of vacuumizing, sealing, printing and cooling at one time. It is mainly used for the packaging of tea, peanut, shrimp, corn and other foods. 3. Single machine multifunction. Multi functions can be realized on a single machine, which can easily expand the scope of use. Modular design must be adopted to realize the multi-function of single machine. Through the transformation and combination of functional modules, it becomes a different type of vacuum packaging machine suitable for different packaging materials, packaging articles and packaging requirements. 4. Form a production 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 combined successfully to build 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 machine are closely combined; In control technology, more computer technology and microelectronics technology are applied; In the aspect of sealing, the application of heat pipe and cold sealing technology can also directly install the advanced device on the vacuum packaging machine, such as the computer-controlled high-precision combined scale for coarse-grained materials; In rotary or vacuum packaging machines, advanced high-speed circular arc cam indexing machines are applied
