In the 1980s, due to the rapid development of the national economy, the rapid expansion of foreign trade, and the obvious improvement of people's living standards, the filling requirements for products are getting higher and higher. It is urgent to realize mechanization and automation of the filling machine, which greatly promoted the development of the filling machinery industry. The filling machine industry plays an increasingly important role in the national economy. In order to promote the rapid development of the filling machinery industry, China has set up a number of filling machine management organizations and industry organizations. Since the 1990s, the filling machinery industry has grown at an average annual rate of 20-30%, which is higher than the average growth rate of the entire filling industry of 15-17%, and 4.7 percentage points higher than the average growth value of the traditional machinery industry. The filling machine industry has become an indispensable and very important emerging industry in our national economy. At present, there are more than 1500 enterprises engaged in the production of filling machinery in China, including nearly 400 enterprises with a certain scale. There are more than 2700 products in 40 categories, including a batch of high-quality products that can meet the needs of the domestic market and participate in international market competition. At present, China's filling machinery industry has a number of backbone enterprises with strong development capacity, which are mainly composed of the following aspects: after technological transformation, some mechanical factories with strong strength produce filling machinery; In order to improve the technical level of the filling machinery industry, a number of filling machinery research institutes and information institutes have been established nationwide, and some colleges and universities have successively established the filling engineering specialty, providing a strong technical guarantee for the development of China's filling machinery industry and catching up with the world's advanced level as soon as possible. Although the domestic filling industry has developed rapidly and made great achievements, compared with developed countries, there are great differences in the variety, technical level and product quality of filling machines. Developed countries have applied mature high and new technologies such as microcomputer control, artificial intelligence, image sensing and industrial robots to filling machinery, and these high and new technologies have just begun to be adopted in China's filling machinery industry; The gap of filling machinery products in China is about 30-40%; There is a certain gap in the performance and appearance quality of filling machinery products. Therefore, we must take strong measures to further accelerate the development of the domestic filling machinery industry and strive to catch up with the world's advanced level as soon as possible.
