Although the level of China's food packaging machinery packaging technology has improved, but China's food packaging machinery packaging technology compared with developed countries in the competition is still in a weak position. About 30% of enterprises in China's packaging machinery industry have low-level redundant construction. This situation has not only wasted important resources such as limited funds and manpower, but also caused chaos in the packaging machinery market, hindered the healthy development of the industry, and restricted the upgrading of packaging machinery and innovation of packaging technology in China's small and medium-sized food enterprises.
China's food packaging machinery is mostly based on stand-alone machines, with low scientific and technological content and automation. It is less applicable to new technologies, new processes, and new materials, and it cannot meet the requirements of China's current food enterprise development. Some food companies have had to spend large sums of money to import some advanced food packaging production lines with advanced technology, high production efficiency, and high packaging precision for a technological transformation, resulting in a large part of the domestic market share being occupied by foreign brands. The development space for food packaging machinery in China is still vast, and the level of food packaging machinery packaging technology needs to be urgently developed.
Main gap between domestic food packaging machinery and international
1, low production efficiency, high energy consumption, poor stability and reliability, product modeling backward, rough appearance, low life of the basic parts and accessories, domestic poor quality pneumatic components and electrical components. For example, Henan Xinghuo Packing Machinery Co., Ltd. is based on the advanced foreign packaging machine technology, based on the transformation and innovation products, the pneumatic part of the Spark brand series filling machine adopts the pneumatic components of Germany 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 in Germany, Italy, the United States and Japan are in a leading position. Among them, the technology for molding, filling, and sealing three kinds of mechanical equipment in the United States has been updated very quickly. For example, the liquid filling machine produced by EJF can realize gravity filling, pressure filling and positive pressure mobile pump filling. That is to say, any viscous liquid can be realized by changing the filling method by microcomputer control. In recent years, this kind of technology has appeared in China, such as Jiangsu Qunjie Packaging Machinery Factory, Guangzhou Ote Packaging Machine Company and so on.
Development status of foreign packaging machinery
Germany
Germany's packaging machinery is world-class in terms of measurement, manufacturing, and technical performance. The beer and beverage filling equipment produced in the country has a fast production speed, a high degree of automation and good reliability. Mainly reflected in: the automation of the process, high production efficiency, to meet the short delivery time and reduce the cost requirements of the process; equipment has a higher flexibility and flexibility. Mainly reflected in the flexibility of production, the flexibility of the 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, can carry out remote diagnostic services; less pollution to the environment , mainly including noise, dust and waste pollution.
Italy
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. The biggest advantage of the Italian packaging machinery industry is that it can be designed and produced in accordance with the requirements of users, and can ensure that design, production, and testing are well completed, and that supervision, inspection, assembly, adjustment, and analysis of user needs are implemented.
Japan
Although Japan's food packaging machinery is mainly based on small and medium-sized single machines, it is small in size, high in accuracy, easy to install, easy to operate, and highly automated.
With the development of world science and technology, developed countries have integrated nuclear energy technology, microelectronics technology, laser technology, biotechnology and systems engineering into traditional machinery manufacturing technologies. New alloy materials, polymer materials, composite materials, inorganic non-metallic materials and other new materials have also been promoted. The integration, intelligence, networking, and flexibility of food packaging machinery will become the mainstream of future development. The future manufacturing industry will exhibit the following characteristics:
Production scale: small batches, small batches, large batches, many varieties, variable batches.
Resource allocation: labor-intensive equipment-intensive information-intensive knowledge-intensive.
Production method: manual mechanization, single machine automation, rigid water line, automatic line, flexible automatic line, intelligent automatic line.
Process method: emphasis on processing before and after processing, attach importance to process equipment, make the manufacturing technology into a complete set of technology, process equipment, process materials as a whole.
Process Control: The control of logistics, inspection, packaging, and storage processes is an integral part of manufacturing technology.
The establishment of a product recycling system: design, production, preparation, processing, manufacturing, sales, maintenance, recycling, and the whole process forms a virtuous circle.
The packaging machinery industry is facing the needs of the market and how to catch up with even beyond the food packaging machinery of developed countries, and how to increase the pace of independent innovation, and strive to develop a group of products with independent intellectual property rights and international advanced level in a short period of time. It is an urgent task facing China's food packaging machinery companies.
Masonry bits typically are used with a hammer drill, which hammers the bit into the material being drilled as it rotates; the hammering breaks up the masonry at the Drill Bit tip, and the rotating flutes carry away the dust.
Hammer drill bits often use special shank shapes such as the SDS type, which allows the bit to slide within the chuck when hammering, without the whole heavy chuck executing the hammering motion.
Masonry bits of the style shown are commonly available in diameters from 3 mm to 40 mm. For larger diameters, core bits are used. Masonry bits up to 1,000 mm (39 in) long can be used with hand-portable power tools, and are very effective for installing wiring and plumbing in existing buildings.
With the prosperity of China’s commodity economy and the improvement of people’s living standards, the prospects for food packaging machinery packaging technology are very optimistic. In recent years, the state has increased its supervision over the quality and safety of foods and medicines, and has put forward new requirements for the production, processing, and packaging of foods. A batch of food production enterprises have invested funds for technological transformation of packaging equipment and innovation of production technology, which has, to a certain extent, improved the level of China's food industry and market competitiveness.
