Textile machinery is the production means and material basis of the textile industry. Its technical level, quality and manufacturing cost are directly related to the development of the textile industry. Generally speaking, the scope of textile machinery covers: spinning machinery, weaving machinery, knitting machinery, dyeing and finishing Machinery, chemical fiber and nonwoven machinery, etc. As the current global textile trade is facing severe challenges such as environmental protection, labor costs, and trade barriers, the upstream textile machinery industry is more dependent on other industrial fields. It is expected to use more advanced technologies to promote product quality and production efficiency. It also includes the industrial automation industry.

According to the statistics released by the China Textile Machinery Association in August this year, in the first half of 2018, the national textile machinery industry achieved a main business income of 55.626 billion yuan, a year-on-year increase of 16.02%, an increase of 3.28 percentage points over the same period of the previous year; the total profit achieved was 3.181 billion yuan, a year-on-year increase of 19.56%; total assets were 103.114 billion yuan, a year-on-year increase of 9.62%, an increase of 3.96 percentage points compared with the same period of the previous year, and the overall industry trend was stable. However, at the same time, due to the continuous increase of labor costs in recent years and the difficulty in recruiting employees, the domestic textile industry is facing huge pressure for transformation and upgrading, and some enterprises have to carry out automation and numerical control transformation.

Reduce costs and increase efficiency, improve textile technology

In the current process of transformation and upgrading of the textile industry, improving the automation technology level of textile machinery is one of the most important key technologies. China's textile machinery production is facing a more intense competitive environment of globalization, which prompts the development of textile machinery and textile machinery automation technology to show new characteristics, including frequency conversion speed regulation technology, motion control technology, programmable control technology, Ethernet fieldbus technology, etc. Advanced technologies including these are increasingly used in the textile machinery industry.

For example, electricity consumption is the main component of textile production costs. The use of frequency conversion energy-saving transformation has become an effective way for the textile industry to reduce the energy consumption cost of dyeing yarn and improve product competitiveness. Frequency converter products can save energy, improve equipment performance, and improve textile technology. play an increasingly important role.

From the perspective of actual production, today's frequency converters have been applied to equipment in almost every process in spinning machinery, such as opening and cleaning machines, carding machines, sliver winding machines, combing machines, drawing frames, and roving frames. , spinning frame and winding machine and so on. In weaving machinery, frequency converters have been applied to sizing machines, warping machines and other equipment; in addition, AC frequency converters have also been widely used in knitting machines, non-woven fabrics, chemical fiber machinery, and printing and dyeing machinery; and Roving frame, spinning frame, winder and various chemical fiber machinery have all used multi-drive technology. The application of field bus technology, common DC bus technology, embedded control technology and multi-core control technology has greatly improved the function of the frequency converter. The large expansion can integrate a variety of control functions according to user needs, and also broaden the application space of the inverter in the textile industry.

The urgent need for intelligent production

After rapid development in recent decades, China's textile industry has a certain competitive advantage in the world and has the prerequisites for the development of intelligent manufacturing. According to the national "Thirteenth Five-Year Plan for Textile Industry", China's textile industry will establish 6 intelligent demonstration production lines for spinning, chemical fiber filament, knitting, printing and dyeing, non-woven fabrics, and clothing and a weaving intelligent production workshop. But in general, at this stage, the textile industry chain is long, and the development progress of intelligent manufacturing in various production links is uneven. Most domestic textile enterprises have only realized automation, numerical control and informatization, and are far from the requirements of real intelligence. far cry.

Taking spinning machinery as an example, this is the largest industry in China's textile industry and the closest to the world's level. In terms of intelligent manufacturing, spinning machinery is also a relatively mature field, and many demonstration lines have been built. In the field of textile and weaving equipment, the construction of intelligent manufacturing workshops should focus on solving the problems of interconnection and interoperability between equipment of different brands, types and models. On-line detection and marking of defects, flexible logistics and distribution, and development of special robots for the industry realize "machine substitution", build a factory interconnection platform, realize online information collection, online quality inspection, and realize big data mining through factory informatization and digitization. In the chemical fiber industry, its requirements for intelligence include: how to improve the efficiency, variety and quality in accordance with the overall design requirements of the smart factory combined with the improvement of chemical fiber processes; Targeted breakthroughs in key process links; how to build an enterprise's own big data application and platform, etc.

Intelligent manufacturing is the deep integration of new generation information technology and advanced manufacturing technology, which runs through all links of the whole life cycle such as product design, weaving, and service, and the optimization and integration of corresponding systems, aiming to continuously improve the product quality, efficiency and service level of enterprises. , reduce resource consumption, promote the innovative, green, coordinated, open and shared development of the manufacturing industry, and finally achieve the goal of improving the comprehensive competitiveness of China's textile industry in the global market.

Since the beginning of this year, the economic situation at home and abroad has been complicated. Driven by many factors such as industrial transfer, cotton policy, and rising domestic weaving costs, the development trend of the textile machinery industry in the future is still uncertain; "The implementation of the development concept, the domestic export market of textile machinery in the "Belt and Road" region is also worthy of close attention. Based on intelligent manufacturing, promoting the strengthening of the textile industry will be the main theme of the development of the textile machinery industry in the next stage. Industrial automation enterprises should actively participate in this construction torrent, and contribute to the intelligent upgrading of textile machinery at the level of key components.
