the paper industry is an industry closely related to the national economy, which directly provides raw materials for people's lives, product packaging, and other industries. Therefore, it has a trend of synchronous development with the gross national product, and its degree of development directly reflects the level of economic development of a region or country. China's paper production has ranked among the top three in the world, but the per capita consumption level is only 27.8kg, only half of the world average, which also truly reflects the current level of economic development in China. Modern paper industry is also a technology, capital, resource and energy intensive industry with significant economies of scale. In short, there is no doubt that the paper industry is a promising industry. What is left to the

paper machinery industry is how to improve the technical level of equipment, produce the products needed by the paper mill, and try to meet the requirements of the paper mill for high quality, low consumption and low pollution

1 current situation and characteristics of papermaking machinery industry

papermaking machinery usually includes special equipment for pulping, papermaking and finishing, as well as general equipment for electrical transmission, automation, computer control, environmental protection and so on. The paper machinery industry is a highly professional industry that directly serves the production of paper mills. At the same time, the development of paper machinery involves a wide range of technical fields, such as machinery, chemical industry, materials, anti-corrosion, pressure vessels, automatic control and so on. Externally, the driving force for the development of paper machinery mainly comes from the paper market. The huge demand of China's paper market has created a broad space for the development of paper machinery. According to the prediction, at the end of the tenth five year plan, the output of paper and paperboard will reach 38-40 million tons, and the new output will reach 8-10 million tons. According to the current production capacity of China's paper machinery industry, it can only meet less than 1/3 of the domestic market demand, but only the market does not mean that paper machinery enterprises can rest easy. According to statistics, in 1995, there were only 16 paper-making enterprises with a scale of more than 100000 tons, and by 2000, it had increased to 44, with a rapid growth. However, the development of paper-making machinery enterprises was slow, the benefits were low, and the market pattern had not changed significantly. This shows that there is a great disconnect between domestic papermaking and papermaking machinery industry, that is, domestic papermaking machinery is difficult to meet the needs of domestic papermaking industry to a great extent. The development of papermaking market in the future is both an opportunity and a great test for the development of domestic papermaking machinery

the development of papermaking industry cannot be separated from papermaking machinery, but the development of domestic papermaking industry is uneven, and the demand is also diversified. Domestic paper mills' choice of paper machinery is mainly based on price, technology, reliability, after-sales service and so on. Enterprises with abundant funds, such as wholly foreign-owned enterprises, joint ventures or enterprises enjoying national interest discount loans, have high requirements for paper machinery and paper products. Therefore, such enterprises often choose to import all or part of key equipment. For these customers, at present, domestic paper machine factories are still difficult to meet their requirements, and can only have some localized equipment in bulk products (such as cardboard, etc.). However, these enterprises are only a few, and the real majority are private enterprises or joint-stock enterprises developed after the reform and opening up. Although some of them have a certain financial strength, they have a strong feeling that the price of imported equipment and large-scale investment are not satisfied, and they have high requirements for product quality. Therefore, they are the direct promoters of the development of domestic paper machinery. The other part is still produced at a low level. Although it also wants to have the plan of technological transformation, the thickness of capital, management, technology and other aspects: the limitation of 1.18 mm makes it stagnant and makes little progress, but once the time is ripe, the potential here can not be ignored. The development of domestic paper machines is always linked with the development of such enterprises. Understanding this is very important for the development of China's paper machinery

papermaking the domestic papermaking machinery industry has also made great progress, especially in the past 10 years, some other industries such as aviation and shipbuilding have participated in the production of papermaking machinery, and the technical level, new product development and single machine scale of products have also been greatly improved, which is also a major contributor to pollution emissions. There have also been many private joint-stock enterprises, some of which have high enthusiasm and consciousness for improving product technology and developing new products, but the basic pattern of this industry has not changed much, mainly manifested in product convergence, lack of characteristics, excessive competition, meager profits, unstable product performance and low technical level. These characteristics show that China's paper machinery industry is still in the primary stage of development. On the one hand, low-grade products are relatively surplus and profits are declining; On the other hand, the demand for high-end products is incompetent, which is the biggest feature of the domestic paper machinery market. The main reasons for the problems are as follows:

papermaking (1) lack of investment. The development of the paper industry has attracted a lot of funds, such as foreign capital, national discount loans, private capital, etc. However, the proportion of foreign capital absorbed by the paper machinery industry is very small, and the investment of private capital is even less. It can be predicted from the commonness of the machinery industry that it will still be difficult to attract a large amount of capital investment in the future

papermaking (2) product convergence, lack of characteristics, and even the scale of many production plants are not different. The low technical content of the products produced has led to price competition, declining profits, and the lack of stamina for enterprise development, making it difficult to embark on the virtuous cycle of production profit reproduction development

papermaking (3) domestic high-grade papermaking enterprises generally have an unreliable understanding of domestic equipment, and turn to imported equipment, which makes it difficult for the products of domestic powerful papermaking machinery factories to stand out, resulting in unclear levels among enterprises and difficult to realize division of labor and cooperation

papermaking (4) due to the low profits of enterprises, it is difficult to attract excellent management and technical talents, and most enterprises can only use their own trained talents. The talent team is uneven, and the ability to independently develop products and innovate, and even the ability to digest and absorb similar foreign products, is very weak

papermaking (5) all domestic papermaking machinery factories have not established Rd centers with pilot equipment. So far, the progress made in papermaking machinery technology is almost a reproduction of foreign products, which are digested, absorbed and copied, and there are few products with independent intellectual property rights

2 development trend of main technical equipment

2.1 continuous cooking system

papermaking with the continuous expansion of the scale of domestic pulping production lines and the continuous improvement of pulping quality requirements, continuous cooking system is widely used. After self-developed and imported technology digestion and absorption, the continuous steaming system, which mainly adapts to grass raw materials, does not use experimental machine system equipment and automatic control for a long time, and has developed greatly and become increasingly mature. It has achieved full localization, with a single line production scale of 50000 tons/year, and is developing towards large-scale and automation to ensure the normal operation of Jinan assaying machine. The domestic continuous steaming system mostly adopts the horizontal tube type, and a few adopt the combination of inclined horizontal tubes. In recent years, many CTMP and APMP production lines have been introduced. At present, domestic equipment is still blank, mainly due to the development of key equipment such as high compression ratio feeder (or extrusion mill) and large-diameter disc mill with pressure and atmospheric pressure
