China's real production of combing machines was in the 1980s, when foreign people joked that the combing machines we produced were semi-combed machines. Today, we saw at the 11th Shanghai International Textile Industry Exhibition that there are about 7 domestic companies engaged in combing equipment, and with new design concepts, they have made breakthroughs in craftsmanship, which is praised by Chinese and foreign counterparts.
On the same stage, the gap is shrinking
At the Shanghai International Textile Industry Exhibition, the CJ40S comber from Shanghai Textile Machinery Plant, JSFA286 from Jiangsu Kunshan Kaigong Machinery Co., Ltd., BS280 from Shanxi Best Machinery Co., Ltd., SXFl272 from Shanxi Hongji Industrial Co., Ltd., and Fujin The FA278 comber from the textile machine company represents the most advanced level of combing machines in China today.
Especially in the increasingly fierce market competition, domestic manufacturers have made many improvements to the combing machine, and its characteristics are reflected in the equipment displayed. The combing machine of the Shanghai Textile Machinery Factory adopts servo motor drive, four-axis linkage and separation roller, which shows a high level of mechatronics. There is also a combing machine of Jiangsu Kunshan Kaigong Machinery Co., Ltd. Frequency conversion speed regulation, accurate and timely braking, wide speed range, high precision, simple operation and maintenance, and humanization.
In addition, the high-clamp production demonstrations are: Shanxi Hongji SXFl272 comber, demonstration speed of 430 clamps per minute, Mazori (Dongtai) CM500N demonstration speed of up to 400 clamps per minute. In such a high-speed operation, the part of the front frame is touched, the vibration is not severe, and the quality of the spun cotton web is not significantly deteriorated.
It is understood that it is necessary to improve the accuracy of the front gear (level 5) and strict assembly quality to achieve the above state. This proves that the mechanical manufacturing level of domestic combing machines has indeed improved, the level of mechatronics has also improved, and the reliability of machines has also improved.
The new E65/E75 comber from the Swiss company Rieter at the foreign pavilion claims to be the first comber in the world to reach 450 clamps per minute. Among them E65 is semi-automatic and E75 is fully automatic. The E65 per hour is 66 kg/h and the E75 is 68 kg/h. Efficiency can be increased to 96% without sacrificing quality. The company's approach is to continue to use CAPD (Computer Aided Process Design) to further optimize the various motion processes of the comber so that the length of the processed raw fiber ranges from 25.4 to 38.1 mm and up to 43.5 mm.
Rieter E65/E75 suitable fiber length, it seems to cause the attention of domestic manufacturers. The 3/3 (representing three ups and downs, the same below) pressure bar drafting replaces the original 3/5 curve drafting, and the rear drafting and the main drafting zone spacing can be easily adjusted to improve the yarn quality. Level. The new top comb Ri-Q-Top is used to improve its online self-cleaning function. The specially designed high-performance cylinder enhances the combing function of the comber.
Design level, behind developed countries
So what about our actual level in terms of combing machines? Wang Shutian, secretary-general of China Textile Machinery Industry Association, believes that the research and development level of China's textile machinery is still at a low level, and most enterprises' research and development awareness is still in a state of transition, and scientific research investment only accounts for about 3% of the company's sales revenue, although these two Years have developed rapidly, but the independent research and development capabilities are still relatively poor.
In addition, China Textile Machinery Industry Association currently organizes some activities on how to improve the industrial design of enterprises, but in fact, China's current design equipment and software are not bad, now CAD, including three-dimensional design, etc. However, our design is still far behind the advanced level of foreign countries.
Therefore, the independent research and development capabilities of textile machinery manufacturers in the Mainland are still very weak, which can be said to be "big but not strong". The performance of mechanical manufacturing is not strong, and the research and development capabilities of advanced equipment and the research and development capabilities of automatic control systems are insufficient. However, with the narrower and narrower roads for textile machinery to buy technology in recent years, some textile machinery enterprises can only carry out independent research and development. Therefore, these years are the fastest growing years of China's textile machinery R&D level, especially domestic cotton spinning equipment. There has indeed been a lot of progress.
Increase investment and improve independent research and development capabilities
For the enterprise, it seems to be a financial problem on the surface, but it is actually a matter of consciousness. Nowadays, enterprises are generally "not interested in R&D." The reason is that the investment is large and the effort is not good. However, the research funding of domestic textile machinery enterprises is far lower than that of foreign textile machinery enterprises. Now the investment of foreign enterprises in research and development accounts for 6% of sales, and some even higher, and the overall R&D investment of textile machinery industry in the mainland enterprises. Only about 3% of sales, and some companies have no research and development investment.
Regarding this issue, the relevant experts said at the same time that the development of China's textile machinery industry must increase investment in research funding and rely on technological innovation to improve independent research and development capabilities.
When the domestic market is connected with the international market, internationally renowned textile machinery manufacturers have settled in China and have formed scale production capacity. From the current situation of purchasing textile machinery products in the textile industry, high-end products mainly rely on imports, and domestic textile machines rely on price advantage in the market to share the same with imported textile products.
However, as foreign-invested enterprises invest and set up factories directly in China, they not only greatly reduce the production costs of their products, but also threaten the comparative advantage of China's textile machinery industry. Therefore, it is the top priority for the textile machinery enterprises in China to make great efforts to improve their independent research and development capabilities.
