It is understood that my country's flexible packaging equipment manufacturing industry only has a history of more than 20 years. It was based on the introduction of foreign equipment and through digestion and absorption. From the initial stage, it could only produce satellite printing machines with a width of 400 mm and a speed of only 20 meters per minute. , dry laminating machines, etc., we are currently able to produce gravure printing machines with a speed of 150 meters per minute and a width of less than 1000 mm, dry laminating machines and various fully automatic bag making machines with more than 100 segments per minute. It provides important equipment for the development of domestic flexible packaging industry.
At present, my country's flexible packaging equipment production has reached industrial scale, forming several large-scale flexible packaging equipment production bases in eastern Guangdong, Wuxi, Jiangsu, Haining, Wenzhou, Zhejiang, and Xi'an, Shaanxi. In the past, my country's bag-making enterprises mainly produced narrow-width fully-automatic bag-making machines, and most of the foreign equipment was imported from Japan. In recent years, with the growth of demand, a large number of imported equipment from Japan and other places have been introduced. This means that there is a large gap between us and advanced foreign countries.
Therefore, during the 11th Five-Year Plan period, my country has put forward requirements for improving the high-tech and equipment level of the domestic flexible packaging equipment manufacturing industry, focusing on the development of advanced equipment with high efficiency, high speed, precision and automation. The technological gap between domestic and foreign countries has made the country that is a big country in flexible packaging equipment move towards a powerful country in flexible packaging equipment.
Looking at the competition among the most advanced fully automated center-sealing bag making machines at home and abroad, the most important thing is the competition in equipment efficiency, that is, competition in high-speed and efficient features.
The equipment used in flexible packaging bag making machines integrates machinery, electricity, light and gas. High mechanization and automation are important directions for its development. It requires high speed and efficiency to reduce target product cost accounting, and requires high flexibility and flexibility to adapt to target product updates and changes.
It adopts PLC human-machine interface computer-controlled automated and digital operating system to facilitate equipment operation and troubleshooting. By pre-entering common equipment faults and solutions into the computer, self-diagnosis and remote diagnosis and troubleshooting can be achieved.
The high-speed and efficient operation and the demand for energy saving and consumption reduction to improve the bag-making speed of middle-sealed composite films have prompted bag-making machine equipment companies to continuously improve the structure while improving the level of automation, and devote more attention to improving the production of the entire packaging system. In terms of efficiency, it enables high-speed development and makes the packaging system more economical and reasonable.
At present, the various technical parameters of advanced equipment for center-sealing fully automatic bag making machines at home and abroad are almost the same, while the main difference between this type of equipment in China is the operating speed of the entire machine. However, there is not much room to simply increase the operating speed of the equipment to improve the working efficiency of the equipment. The most advanced equipment is stuck at 12000P per hour, which has become the bottleneck of the equipment's performance.
At present, through research and development, we have developed a high-speed middle sealing machine that does not rely solely on the equipment speed, but by transforming the equipment's single-row bag making mode and other methods to further improve the work efficiency of the equipment, so that the equipment can maintain a higher speed, more efficiency and a comprehensive degree of automation. The industrial production and promotion of fully automatic bag making machine equipment has become an urgent problem that many domestic flexible packaging bag making equipment companies need to solve.
