Mastering core technology as soon as possible is the key

in recent years, the demand for domestic printing equipment has increased at an annual growth rate of 10%; This makes China a recognized market in the world. In fact, there is a demand for various grades of products in the domestic and international printing machine market, but the mid-range market potential is greater. Relevant experts believe that the market capacity of domestic printing equipment was 120 yuan in 2000, and will reach billion yuan by 2005. However, at present, domestic printing equipment accounts for only 28% of the domestic market share, which is extremely incompatible with China's rapid economic development. The market puts forward higher requirements for domestic printing machinery manufacturing enterprises

China's low cost printing equipment 70% depends on imports

common problems in the testing of printing exterior wall insulation materials in China at present, the scientific and technological level of equipment has not kept up with the pace of international technological progress, and there is a big gap. According to the statistical data of China printing and equipment industry association in 2001, at present, more than 70% of China's printing equipment depends on imports. In terms of prepress equipment, "digitalization and networking" is the development direction. Digital equipment is mainly CTP plate making equipment and related supporting equipment, and its supporting digital cameras and digital proofing machines all rely on imports. In terms of printing equipment, the supply and demand of medium and low-end products are basically balanced, and high-end equipment mainly depends on imports. From 1998 to 1999, 420 sheet fed offset printing machines were imported, 79 domestic machines, and the market share of imported machines is 84.17%. There are about 30 domestic commercial web offset printing machines, only one of which is domestic

there are indeed some unreasonable phenomena in the domestic printing machine market. For example, in some product fields, no matter the size of enterprises, they compete cruelly in the medium and low-end product market, and have no time to care about product upgrading, giving up the medium and high-end product market

at present, domestic printing machine enterprises are facing problems such as outdated management mode, backward technology, poor innovation ability and so on. The solutions are: joint venture and cooperation with foreign advanced enterprises, asset reorganization, ownership transformation, etc., but the key is to solve the deficiencies and deficiencies in concepts, systems, mechanisms, innovation capabilities, knowledge structure, etc.: This paper only gives some insights on catching up with foreign advanced printing machinery through technological innovation. The ultimate goal of technological innovation is to master the core manufacturing technology of printing machinery

the technical gap between domestic and foreign printing equipment

compared with the products of Heidelberg, MAN Roland, gaobao, Komori and Mitsubishi in the 1980s and 1990s, it can be seen that although the speed is also significantly improved, there is no fundamental change in the mechanical body. They focused on improving the automation and intelligence level of equipment, such as automatic rubber washing, automatic printing, ink remote control; Automatic fault monitoring, etc., thereby shortening the auxiliary time and improving the efficiency of printing machinery. Of course, the corresponding mechanical body has also made some changes, such as pneumatic release pressure, etc

products in the 1990s are electromechanical products, which are the product of the combination of printing machinery technology and information technology. Information technology extends human senses and enlarges part of human intelligence. As early as the early 1990s, words such as "mechatronics" and "mechanocs" appeared in their samples. Their innovation methods are mainly combined innovation methods, such as ink remote control. This is also the main innovative method since the 1950s

the gap between our products and foreign products is manifested in two aspects: first, the gap between mechanical ontology and second, the gap between automation and intelligence. Therefore, our catch-up work is to improve the stability, reliability and industrialization level of the machine body, and to improve the automation and intelligence level of the machine

if the stability and reliability of the mechanical body structure are realized, it will meet the requirements of medium-sized type

practical possibility and necessity of bridging the gap

1 The leading design has been clearly placed in front of us. For example, for the flat sheet multi-color machine, vacuum paper suction, seven o'clock arrangement, double diameter roller, alcohol fountain and so on are well-known facts

2. The technical track is very clear - for example, the unit type realization of multicolor printing

3. The above two items save us the energy of exploration, that is to say, we should focus on the optimization of components

4. Realize specialization on the basis of component optimization

5. For the machine body, it is important to complete the requirements of

ability. The factors that affect the completion of functional requirements are nothing more than the mechanism and structure of the machine, the vibration, load and speed fluctuation of the machine. In fact, the optimization of mechanism and structure, the analysis and testing of vibration, the balance of mechanism seismic force and other technologies have been mature in China, and there are also a large number of talents who master this technology. What is needed is how to use these talents, and how to apply the indomitable spirit of "fighting hard and fighting hard" - to design practice and technical politics

after the WTO, the path of technical cooperation is becoming wider and wider. For example, OEM of automation components can be developed jointly

the necessity of bridging the gap

1 With the gradual mastery of core technology, the cost of production and manufacturing can be reduced. For example, the loss of paper, ink and power during test run can be greatly reduced

2. Create customer value, improve the stability, reliability and efficiency of the machine, save customers' costs and improve customers' competitiveness; At the same time, it can save three guarantees

3. Competing with foreign advanced printing machines at a similar technical level can reduce the technical differentiation, so it can better highlight our low-cost advantage and improve product competitiveness

because of the above three, we can seize the market of medium and high-end printing machinery

steps and ways to solve technical problems

steps

if the level of automation and intelligence is improved, the mechanical body still fails, which is also in vain. The machine with qualified mechanical body structure is a mid-range machine, which can also divide part of the market. Judging from the current strength, we can't go in unison. The mechanical body is the foundation, which should be developed first, followed by automation and intelligence

approach

first, strengthen analysis and testing. Marx said, "the division of economic times does not lie in what to produce, but in how to produce and what tools to use.". That is to say, it is not about what to do, but how to do it. Now it is the era of information society and knowledge economy. The means to tackle key technical problems and bring products to the market are mainly analysis and testing. Academician Yan puqiang pointed out that "human understanding of nature always begins with testing". That is to say, the core technology is based on analysis and testing

at present, the technical analysis work of enterprises in the industry is mostly qualitative, and there are few quantitative calculations. Even if there is quantitative analysis, it is mostly motion analysis, and there is little dynamic analysis. Now the main content of the design work is surveying and mapping, imitation and introduction, which is understandable. This is one of the four types of design work, and analysis and testing can help us to analyze the difference in dynamic performance. For high-speed h.200 ± 20mm/min or 250 ± 25mm/min; The power performance of printing machinery is particularly important

at present, the test work is almost zero. The test is just a stack of paper, and the means are too simple and backward. Analysis and testing should complement and correct each other

the means of testing is sensors. Sensing technology is one of the three foundations of information technology and the extension of human senses. Today, there are resistive, inductive, capacitive, photoelectric and everything. There is no problem with the testing work. It is considered that the transmission accuracy of gears can be tested under the running state, which is very helpful to analyze the impact of gears on overprint accuracy and ghosting. What matters now is not whether there is a means of analysis and testing, but where and how to use it

in addition, we should also strengthen the current research on machining technology and assembly technology, such as the adjustment method of paper delivery teeth, the assurance method of tooth backlash, the assurance method of wallboard joints, and so on

second, improve the talent structure and the structure of human resources. The cause must be done by people, "the ultimate foundation of national wealth is human resources". Enterprises can first separate people with this specialty from daily product design, and at the same time recruit some highly educated and high-quality talents to set up a department, combining the old, middle-aged and young people, taking the existing problems of products as a breakthrough, carry forward technical democracy, and analyze and eliminate countermeasures according to priorities, such as overprint accuracy and influencing factors, finite element analysis of frame and roller, printing pressure test The causes and Elimination Countermeasures of ink bars should be broken one by one, and the basic technology research work should be carried out. Finally, the transition should be to master the working rules of printing machines and have their own core technology, so as to form the core competitiveness combined with low cost

second, strengthen component design and realize specialization

third, strengthen cooperation, cooperate with domestic counterparts, scientific research institutions, colleges and universities, and strengthen technical exchanges with foreign countries

in a word, the technology and means are ready-made. The key is to use it in the field of printing machinery manufacturing, and the innovation method is still combinatorial innovation. I believe that domestic enterprises will overcome the barrier of core technology, and be able to better meet the needs of the domestic market, create a better living space for themselves, and better meet the needs of the domestic market
