New trend of world packaging machinery

at present, the countries with high level of foreign packaging and food machinery are mainly the United States, Germany and Japan. The author has repeatedly carried out technical training of pulse reflection cable fault tester for Beijing power supply system, Italy and Britain. German packaging machinery is in a leading position in terms of design, manufacturing and technical performance. In 2002, the output value of German packaging machinery reached 3.4 billion euros, and 77% of its output was export products. In recent years, the development of packaging and food machinery and equipment in these countries has shown a new trend

the degree of automation of technological process is getting higher and higher. At present, automation technology has accounted for more than 50% of the packaging production line, and a large number of computer design and electromechanical integration control are used to improve productivity, improve the flexibility and flexibility of equipment, and increase manipulator to complete complex packaging actions (simulate manual packaging). Each manipulator is controlled by a separate computer. The camera monitors the packaging action and feeds back the information to the computer to adjust the action range and ensure the high quality of packaging. At the same time, it has the function of automatic identification of packaging material and thickness, and then the computer calculates and controls the mechanical action. It is a completely "self-adaptive" system to ensure that the system works in the optimal state. Improve production efficiency, reduce process cost, and meet production requirements to the greatest extent. At present, the beer and beverage filling equipment in Germany has reached 12000 bottles/h, and the cigarette packaging machine has reached 12000 pieces/min. Once the high-speed equipment fails, the loss is also amazing, so the high-speed equipment must have a fault analysis system (self diagnosis system) and be able to eliminate the fault by itself, so as to improve the productivity

adapt to product changes, and the design has good flexibility and flexibility. In order to meet the needs of competition, the cycle of product upgrading is getting shorter and shorter. Some products even change every season, and the output is large. The life of packaging machinery is far longer than the life cycle of dry products. Therefore, some packaging machinery can only adapt to the changes of products with flexibility and flexibility, including the flexibility of quantity, structure and supply. The structure can be modular and the supply is flexible, which means that one machine can realize a variety of packaging combinations, with multiple feeding ports and different forms of packaging

strong supply capacity in complete sets. For example, a beverage filling line has more than 200 microcomputer components and more than 100 control software. The filling and capping part is a combination of two sets, which are shared by other parts. A supplier can carry out engineering design, installation and commissioning for users, and finally submit them to users for acceptance

simulation design technology is widely used in the design of packaging machinery. All kinds of machine units are stored in the computer in the form of database, and the drawings are digitized and input into the computer. The computer automatically synthesizes the three-dimensional model I, and then inputs the actual production indicators and data, possible faults, etc. into the computer. The computer three-dimensional model can be operated according to the actual working conditions. 229 building wooden doors and windows demonstrate the production capacity, scrap rate, production link matching, where the bottleneck of the production line is, etc. the model can also be modified according to the user's opinions until the user is satisfied. The mixture obtained by using computer simulation technology becomes high-strength, which greatly shortens the design cycle of packaging machinery and the development cycle of new products

in addition, the cold sterilization technology developed in the late 1980s has been applied abroad, including ultra-high voltage sterilization, ultra-high voltage pulsed electric field sterilization, strong magnetic pulse sterilization, pulsed strong light sterilization, microwave sterilization, radiation sterilization, ultraviolet sterilization, ozone sterilization, ultra sonic sterilization, high-energy ray sterilization and low-temperature regulation sterilization. In addition, biological preservation technology, active packaging technology, barrier (barrier) technology, membrane separation technology and antibacterial packaging technology are the latest technologies in food processing and packaging. Food ultra-high pressure processing technology is known as "a revolution in the food industry", "top ten cutting-edge technologies in the world today", etc. Cold sterilization, also known as physical sterilization, is a new contemporary technology. In order to maintain the physiological activity of food functional components and how to solve the external interference of color, aroma, taste and nutritional components, it is very necessary to adopt cold sterilization technology in the design and manufacture of food packaging machinery
