ã€Chinese Packaging Network News】 Packaging machinery refers to the completion of all or part of the product and product packaging process machinery. The packaging process includes major processes such as filling, wrapping, and sealing, as well as related processes such as cleaning, stacking, and disassembling. In addition, packaging also includes processes such as metering or stamping on packages. The use of mechanically packaged products can increase productivity, reduce labor intensity, adapt to the needs of large-scale production, and meet the requirements of cleanliness and hygiene.
The development of packaging machinery provides the necessary guarantees for the modern processing and mass production of foods and pharmaceuticals. Due to the peculiarity of drug production, the packaging of drugs from materials to packaging methods, from environmental requirements to label processing, is more stringent than food packaging, and the restrictions are even more stringent. This makes the pharmaceutical packaging machinery develop into a relatively independent machinery industry.
Small and scattered situation to be broken
The domestic packaging machinery industry has followed the expansion of the packaging market, followed by the bottleneck of the "small and scattered" pattern. On this issue, we should focus on the related aspects of packaging machinery and equipment materials and technology. The development of packaging technology has developed with the demand for commodity circulation. For goods, packaging is mainly used to protect, isolate, quantify, decorate and explain. This is also the function and characteristic of traditional packaging.
With the development of commodity economy, the functional requirements of goods for packaging have become stronger and stronger, and the intelligent packaging has become an imperative trend in the development of commodity packaging.
From a broad perspective, after the founding of New China, China's basic packaging machinery industry began its development. After more than half a century of development, there is still a considerable gap between the international advanced level and the advanced level. Among them, only corrugated-carton packaging machinery and some small-scale packaging machines have a certain scale and advantages in China. In addition, some high-tech packaging equipment still need to rely on imports.
According to statistics, in 2005 China's packaging machinery production reached 670,000 units, and by 2010 it will increase to 930,000 units. At present, China's packaging machinery has become one of the ten industries in the machinery industry. However, the export value of China's packaging machinery is still less than 5% of the industry's total output value, but the import value is roughly equivalent to the total output value.
Take April-August 2006 as an example for a group of data on China's packaging machinery import and export. During this period of time, China exported 5,481 units of container washing or drying equipment, and the total export value reached US$ 482,793. Although there were only 345 imported similar equipment, the total import amount was US$ 10,571,652. Packaging, labelling, and filling machines are products of relatively large export volume in China. In the four months, they exported a total of 488,056 units and exported a total of 11,064,972 US dollars. However, 2,878 units of similar equipment were imported, but the total amount of imports also reached. 44,000,035 US dollars. Fillers and packaging machines exported 65,324 units, which totaled US$25,350,635. Imported 566 units totaled 39,213,071 units.
From this set of data, we can see that the average unit price for imported equipment is US$2,475,1.8. Imports are mainly concentrated in developed countries and regions such as Europe, the United States, Japan, and other countries. China's exports are mainly concentrated in Africa and the Middle East. Although the total number of export equipment in China is 558,861 sets and imports only 3,789 sets, the average price of imported sets is 678 times the average price of export sets. This shows that China's export structure presents a "small and scattered" situation, mainly single product; while imported mostly complete or large equipment. It can be seen that China's current export of packaging machinery compared with imports, both in terms of product quality, quantity, and technical content, have a considerable gap with foreign products.
From the perspective of product structure, there are about 1,300 varieties of packaging machinery in China, with a small number of supporting products, lack of high-precision and large-scale products, and can not meet the market demand. The product quality gap is manifested in poor product performance stability and reliability, unsightly appearance, rough surface treatment, poor quality of many components, short life, and low reliability, affecting the overall product quality; from the perspective of the company, domestic packaging machinery The industry lacks leading enterprises, and there are not many companies with large production scales and high product quality. From the perspective of product development, China still stays at the imitation stage. Its self-development capacity is weak, research funds only account for 1% of sales, and foreign countries account for 8% -10%. In general, China's packaging machinery is at a disadvantage compared to internationally advanced products in terms of product development, performance, quality, reliability, and service.
Of course, as a whole, at present, most of the research and development of packaging machinery with advanced data technologies in China are still in the imitation stage, and the capacity for independent development is still very limited. For this reason, many large foreign companies have introduced their own technologies and components into China and processed them locally, which has reduced the cost and launched fierce competition with local products.
High-precision directions have made it clear that the packaging chain is highly automated. Most of the packing work of domestic food factories and pharmaceutical factories, especially the arrangement and assembly of more complicated packaging items, is basically a manual operation, and it is difficult to ensure the unity and stability of the packaging, which may result in contamination of the packaged products.
Some food factories and pharmaceutical companies use packaging machinery only for a certain part of the whole packaging chain. For example, the front packaging adopts mechanical packaging, while the latter packaging uses manual labor. Therefore, improving the automation level and quality level of the entire packaging chain is a very important part of the modern enterprise's implementation of the GMP specification. Every manipulator of a truly modern packaging machine should be controlled by a computer and have a high resolution of material and thickness.
Diversified mechanical functions. Food and pharmaceutical products have been trending towards refinement and diversification, with fewer and fewer products of a single variety and a large quantity, while products of many varieties and small batches are increasingly becoming mainstream. Under the changing trend of the big environment, a diversified, multi-switching function that can adapt to a variety of packaging materials and mold replacement packaging machine can adapt to the needs of the market. For example, in a blister packaging machine, both aluminum-plastic packaging and aluminum-aluminum packaging can be performed, and it is required that the switching is simple and that less molds need to be replaced. At present, the time for replacing molds is generally 1-2 hours, and such a long time can not meet the production requirements of many varieties and small batches.
Structural design standard modular. For the traditional industrial design, if you want to introduce a new model, you need to do a lot of heavy work, but also rely on new equipment to recover the high design costs, thus driving up the price of new models. The design of the future should adopt the design concept of standardization and modularization. It can make full use of the original organic modular design. It can be converted into a new model in a short time, and the price of the new model can be controlled within a reasonable range. Inside.
Intelligent control function. The control system is the brain of the mechanical equipment and is the core device for issuing motion instructions. Currently, manufacturers of food and medicine packaging machinery generally use programmable controllers (PLC controllers), which do not have the powerful functions of industrial PCs. For most conventional mechanical control devices, the use of a PLC is appropriate because there are a limited number of control parameters that need to be controlled mechanically in many places. For example, torque control uses mechanical clutches to overload the motor. However, with the increase in the degree of automation of the equipment, more and more computer-controlled equipment, various sensors applied to the equipment can not manage and control such a large number of parameters, and the industrial PC will be the best choice.
China's packaging machinery must meet the rapid development of the pharmaceutical industry, and actively participate in international competition, we must break the "small but scattered" industry trend. Industry insiders also believe that in the future, the packaging industry will cooperate with the trend of industrial automation. In terms of technology development, it will develop in several directions such as diversification of mechanical functions, standardization of structural design, modularization, intelligent control, and high-precision structure.
