In our country, most of the food packaging machinery is mainly controlled by single machines. Less than 10% of the equipment applies PLC, industrial control computers, DCS, and fieldbus technology. The transmission of food and packaging production lines is mainly based on mechanical transmission. The comprehensive application level of control technology and drive technology is low, and the system cannot achieve optimal design. Due to the low technical level of manufacturing enterprises, sensor and detection technologies, positioning control, and online monitoring are not fully utilized, resulting in a significant gap compared with foreign advanced control technologies.
In the food packaging machinery market, apart from products aimed at individual users that are mainly manually operated, improving the degree of automation and product quality has become the main demand for domestic food packaging enterprises regarding machinery. Meanwhile, due to the expansion of the mid-to-high-end food packaging machinery market and the improvement of automation levels in the low-end food packaging machinery market, food packaging machinery manufacturers have begun developing mid-to-high-end food packaging machinery products at international standards. The development trend of automation in international food packaging machinery is reflected in five aspects:
