Although the level of China's food packaging machinery packaging technology has improved, China's food packaging machinery packaging technology is still relatively weak in competition compared with developed countries. About 30% of enterprises in China's packaging machinery industry have low-level redundant construction. This situation not only wastes limited resources such as capital and manpower, but also causes disorderly chaos in the packaging machinery market, hinders the healthy development of the industry, and restricts the upgrading of packaging machinery and the innovation of packaging technology in China's small and medium-sized food enterprises.
China's food packaging machinery is mostly based on single machine, with low technology content and low degree of automation. It is less applied in new technologies, new processes and new materials, and cannot meet the requirements of the current development of food enterprises in China. In order to carry out technological transformation, some food enterprises have to spend a lot of money to introduce some complete sets of food packaging production lines with advanced technology, high production efficiency and high packaging precision, resulting in a large part of the domestic market share being occupied by foreign brands. The development space of food packaging machinery in China is still broad, and the level of food packaging machinery packaging technology needs to be urgently developed.
The main gap between domestic food packaging machinery and the international
1. Low production efficiency, high energy consumption, poor stability and reliability, poor product shape, rough appearance, low life of basic parts and components, and poor quality of domestic pneumatic parts and electrical components. For example, Henan Xinghuo Packaging Machinery Co., Ltd. is carrying out transformation and innovation on the basis of foreign advanced packaging machine technology. The pneumatic parts of the Xinghuo brand filling machine adopt the pneumatic components of German FESTO and Taiwan AirTac.
2. Control technology is applied less. Such as remote control technology, stepper motor technology, information processing technology. Experts pointed out that the world's packaging machinery level in Germany, Italy, the United States and Japan is in a leading position. Among them, the technology of forming, filling and sealing three kinds of mechanical equipment in the United States is very fast. For example, the liquid filling machine produced by American Liquid Filling Equipment Company (EJF) can realize gravity filling, pressure filling and positive pressure moving pump filling. That is to say, any viscosity liquid can be realized by changing the filling method by microcomputer control. In recent years, this technology has appeared in China, such as Jiangsu Qunjie Packaging Machinery Factory, Guangzhou Aote Packaging Machine Company and so on.
Development status of foreign packaging machinery
German packaging machinery is the world in terms of metering, manufacturing and technical performance. The beer and beverage filling equipment produced in the country is fast in production, high in automation and reliable. Mainly reflected in: automation of the process, high production efficiency, meeting the short delivery time and reducing the cost of the process; the equipment has higher flexibility and flexibility. Mainly reflected in the flexibility of production, the flexibility of construction and the flexibility of supply to meet the needs of product replacement; the use of computer and simulation technology to provide complete sets of equipment, low failure rate, remote diagnostic services; less environmental pollution It mainly includes noise, dust and waste pollution.
40% of the packaging machinery produced in Italy is food packaging machinery, such as candy packaging machines, tea packaging machines, filling machines, etc. The product is characterized by sophisticated appearance, excellent performance and low price. The great advantage of the Italian packaging machinery industry is that it can be designed and produced according to the requirements of users, and can ensure the design, production and testing are well completed, and supervision, inspection, assembly, adjustment and user demand analysis are realized.
Japan's food packaging machinery, although mainly small and medium-sized single machine, but the equipment is small in size, high precision, easy to install, easy to operate, and high degree of automation.
With the development of science and technology in the world, developed countries have integrated nuclear energy technology, microelectronics technology, laser technology, biotechnology and systems engineering into traditional mechanical manufacturing technology. New materials such as new alloy materials, polymer materials, composite materials and inorganic non-metal materials have also been promoted and applied. The integration, intelligence, networking and flexibility of food packaging machinery will become the mainstream of future development. The future manufacturing industry will present the following characteristics:
Production scale: small batches, small varieties, large batches, multiple varieties and batches.
Resource allocation: labor-intensive equipment-intensive information-intensive knowledge-intensive.
Production mode: manual mechanized single machine automatic rigid flow automatic line flexible automatic line intelligent automatic line.
Process method: Emphasis on processing before and after processing, paying attention to process equipment, making manufacturing technology become a complete set of technology integrating process methods, process equipment and process materials.
Process Control: Control of logistics, inspection, packaging, and storage processes as part of manufacturing technology.
Establish a product circulation system: design, production, preparation, manufacturing, manufacturing, repair, recycling, and the whole process forms a virtuous cycle.
The packaging machinery industry is facing the market demand and how to catch up with food packaging machinery that even surpasses developed countries, and how to increase the pace of independent innovation, and strive to develop a batch of products with independent intellectual property rights and international advanced level in a short period of time. It is an urgent task placed in front of China's food packaging machinery enterprises.
