The continuous improvement of the automation level of automatic packaging machines

The packaging industry abroad is developing towards full automation. The widespread adoption of automatic packaging machinery and automatic packaging production lines can achieve low-cost requirements. As a rapidly developing economic entity, our country is growing into an international manufacturing and packaging center, and the demand for various automatic packaging production lines will further increase. Experts point out that compared with foreign packaging line manufacturers, domestic manufacturers still have some gaps in production line supporting function consistency, equipment stability, and service life. To meet the rapidly growing domestic packaging demand, relevant enterprises need to strengthen research on specialized packaging line technology and product transformation to better seize the development opportunities in the domestic market. The Twelfth Five-Year Plan provides 100 to 200 billion yuan worth of equipment for the packaging and food industries, and 80 to 100 billion yuan worth of equipment for the "vegetable basket" project, which is a good development opportunity for packaging enterprises. Nowadays, with the increasing scale of China's food packaging market, the growing complexity of product varieties, and the continuous improvement of production automation levels, it is believed that the research and production of domestic food packaging machines will achieve significant breakthroughs in the near future.

With the accelerating pace of domestic life, on-site food preparation has become a symbol, and more and more packaged products are entering people's lives. Whether in the car, on the road, or in the office, whenever hunger is felt, opening vacuum-packed food is so convenient. Food packaging automation is rapidly entering people's daily lives, creating a trend of convenient living!

According to authoritative expert estimates, the global machinery market demand is growing rapidly at an annual rate of 5.2%, and is expected to reach 39.8 billion USD by 2012. In the coming years, the market sales of packaging equipment in developing countries will surpass those of developed countries such as Japan and the United States. In 2010, China's demand for packaging machinery equipment was about 3.3 billion USD. According to estimates by the China Machinery Industry Federation, during the Twelfth Five-Year Plan period, the scale of China's packaging machinery industry is expected to exceed 600 billion yuan. With the improvement of automation levels, the operation, maintenance, and daily upkeep of packaging machines have become more convenient and simple, reducing the professional skill requirements for operators. The quality of product packaging is directly related to the temperature system, main machine speed accuracy, and the stability of the tracking system. After the machine starts running, the film mark sensor continuously detects the film marks (color marks), while the mechanical part's tracking micro switch detects the position of the machine. These two signals are sent to the PLC, and after program calculation, the PLC outputs Y6 (forward tracking) and Y12 (reverse tracking) to control the tracking motor's forward and reverse tracking. This timely detects errors in packaging materials during production and accurately compensates and corrects them, avoiding waste of packaging materials. If the detection cannot meet technical requirements after a predetermined number of tracking attempts, the machine can automatically stop for inspection to avoid producing defective products. Because variable frequency speed regulation is used, chain transmission is greatly reduced, improving the machine's operational stability and reliability, and reducing operational noise. This ensures the packaging machine's high technical level with low loss, automatic detection, and other multifunctional, fully automatic features. Although the transmission system used in the automatic packaging machine is relatively simple in function, it has high requirements for dynamic transmission performance, requiring fast dynamic response and high speed stability and accuracy.
