According to Li Dongping, director of the Rubber Machinery Committee of the China National Chemical Equipment Association, China's rubber machinery now has a strong foundation and conditions. After the national “8th Five-Year Plan†period, key equipment and raw materials for radial tire digestion and absorption of domestically produced one-stop projects, “Tenth Five-Year†period, and the key equipment development projects for radial tires and engineering radial tires research projects, the Chinese rubber machinery industry has achieved an overall Jumping development. At present, China has possessed the ability to provide a full set of radial tire production equipment and the ability to turn-key projects, which is unmatched by any other single country in the world. In particular, after years of rapid development, domestic rubber machine manufacturers have accumulated a certain amount of technological transformation, and several large-scale rubber machine companies have the capability of independent innovation.
It is understood that China currently has more than 240 patents for rubber machine technology, including more than 50 invention patents. In addition, Guilin Rubber Machinery and Tianjin Saixiang have also been listed as national patent pilot units; Tianjin Saixiang Enterprise Technology Center has been rated as a national-level enterprise technology center; Yiyang Rubber Machinery and Qingdao Software Control have established national post-doctoral workstations last year. This year, they both applied for state-level enterprise technology centers. Some large rubber machine companies account for 8% to 10% of sales revenue in new product R&D. This effort is very large.
It is with this positive sense of innovation and innovation that in recent years domestic new rubber products with proprietary intellectual property technology have been continuously introduced to the market, effectively supporting the development of the rubber industry. For example, Yiyang Rubber Machinery has re-innovated through the introduction of technology and has developed more than 20 types of internal mixers, including the world's largest GN650 and GE580 mixers. The GE250 mixer also achieved the first export of Chinese rubber machines to Europe. . The key equipment for all-steel radial tires, such as the all-steel radial tire building machine, cutting machine, and hexagonal wire ring production line developed by Tianjin Saixiang, is independent of any technical data and through cooperation with tire companies. The research and development filled the gaps in the domestic market, breaking the blockade and monopoly of international tire giant companies on radial tire radial tire technology and equipment, and creating conditions for the development of Chinese all-steel radial tires. This year, the National “863†project they undertook—the development of complete steel radial tire assembly equipment passed the acceptance of the Ministry of Science and Technology. Tianjin Saixiang has also developed the largest domestic and international 2428 passenger/light-card automatic one-time molding machine, and on April 25th it was used by Guangzhou Huanan Tire Company to produce China's first world-class 305/30R26 S-1089. Flat high-performance tires, once again fill the gaps in the country. Domestic steel wire calenders that have long been dependent on imports have also been successfully developed by Dalian Rubber Plastics Machinery Co., Ltd. in May this year, which means that the last technical "fortress" for domestic production of key equipment for all-steel radial tire production in China has been conquered. In addition, the four composite extruders developed by Guilin Rubber Industry New Technology Development Industry Corporation, the all-steel four-drum molding machine of the Beijing Aviation Manufacturing Engineering Institute, the auxiliary machine system of the Qingdao soft-controlled mixer, and the tire dynamic balance testing machine , Guilin rubber machine hydraulic presses and other innovative products, have reached the international advanced level.
In addition, the reporter learned that Chinese rubber machines still have a lot of potential to tap in the industrialization of scientific and technological achievements. On the one hand, colleges and universities and scientific research institutes have developed and mastered many scientific and technological achievements of rubber machinery, but they suffer from no funds and cannot be industrialized. On the other hand, some rubber machine companies suffer from lack of good products and lack of development stamina. For example, Prof. Lu Baiyuan of Qingdao University of Science and Technology has spent more than 30 years researching and developing the electric spiral tire shaping vulcanizer. Compared with the traditional vulcanizing machine, it can save 40% to 50% of steel, simple structure, suitable for large-scale production of high-grade radial tire, low operating cost. . This is a good result, because no one has ever dared to eat "crab" and can not be promoted. At the annual meeting of the rubber machine, Qingdao HKUST signed a technology transfer agreement with Guilin Rubber Machinery Co., Ltd. The Guilin Rubber Machinery Factory produced an electric spiral tire shaping vulcanizer. This industry is a lot of encouragement, and other rubber machine companies boldly adopt new technologies and achieve the industrialization of scientific and technological achievements. It also allows the industry to see more prospects for the application of innovative products. The reporters found that the innovative technologies in these quibbles are mostly energy-saving, resource-saving, and efficiency-enhancing technologies that meet the needs of energy-saving and emission-reduction companies.
Li Dongping emphasized that the world's rubber machinery is showing a trend of development from sensing to digitization, continuous development of equipment to linkage, development of performance to high quality, high efficiency and low cost, and development of technology in an innovative direction. Therefore, domestic rubber machine companies must keep up with this trend; in the traditional tire production equipment, more research should be done in the stability of the product. In the automatic tire production equipment, we must pay attention to the development trend of the world's tire industry, start early. Research; should be combined with the tire industry to develop a circular economy trends, in product development, consider as much as possible to improve efficiency, save energy, reduce pollution. It is understood that some rubber machine companies have cooperated with universities and research institutes to research and improve the efficiency of existing equipment and develop new energy-saving products.
After 20 years of development, China's rubber machinery has gradually grown from small to large, and is currently developing in the direction of independent innovation and brand building. At present, domestic rubber machines can not only fully meet the needs of domestic companies, but also have a good reputation in the international market. China Rubber Machinery provides a reliable equipment guarantee for the large-scale development of the domestic rubber industry.
The rapid development of the Chinese rubber industry, especially since the beginning of the new century, the round of investment fervors such as all-steel radial tires, engineering tires, semi-steel radial tires, etc., have provided an endless stream of Chinese rubber machinery. Orders have also made Chinese rubber machine manufacturers in recent years basically in a situation where their products are in short supply. At present, the sales volume of rubber machines in the Chinese market accounts for 23% of the world's total, which is 6 percentage points higher than that of Western Europe. It has been ranked at the top of the world for three consecutive years. However, in the face of this hot production and sales situation, the chief executives of domestic key rubber companies have performed quite rationally. In an interview with reporters, they all stated that although the company’s order tasks were too busy, they still believed that they should not blindly expand their production scale, but should pay attention to technology and product innovation. Only companies with independent intellectual property rights can use technologies and products. Invincible, China's rubber machine can become bigger and stronger. Innovation is also a theme of the 2007 China Rubber Machinery Annual Conference held on September 2.
