Breakthroughs Depend On Imports And Breakthrough Of Key Components Of Domestic Automatic Winder

< p > the superplastic grooved drum of automatic winding machine developed by the China Textile Machinery Research Institute and the Beijing superplastic New Technologies Inc has gained significant technological breakthroughs recently.

In 2013, the project was listed as < a href= "http://www.91se91.com/news/list.aspx ClassID=101112107101" > China Textile Industry Federation < /a > Science and technology guidance project. After nearly a year's development, the superplastic alloy tank has been appraise by domestic experts.

< /p >

< p > early in the late 80s of last century, the common winder widely used in China, because of its slow speed, needed a large number of artificial joints, which made the product quality unstable and consumed a lot of manpower. < a href= "http://www.91se91.com/news/list.aspx ClassID=101112107102" > production efficiency < /a > low, neither yarn quality nor production efficiency could meet the needs of modern textile.

With the requirement of large-scale production of the global textile industry, the automatic winding machine instead of the traditional winding machine becomes the inevitable trend of modern textile scale production. It is also the basic guarantee for cotton spinning enterprises to improve quality, reduce costs, improve efficiency and competitiveness.

In particular, the number of automatic winding machines directly reflects the level of textile technology in a country.

< /p >

< p > however, for a long time, the market of automatic winder at home and abroad has been controlled by textile machinery enterprises such as Germany, Italy and Japan. In order to change this situation, our country introduced the Italy complete sets of technology from Qingdao Hongda Textile Machinery Company as early as 90s of last century, and developed a new digital automatic winding machine. This is also one of the ten new key equipment of textile machinery supported by the state during the "11th Five-Year" period.

< /p >

< p > however, after more than 20 years of development, the three key parts of the automatic winder, the groove barrel, the electronic yarn clearer and the adhesive device, are imported mainly, especially the slot barrel is an obstacle to the localization of the automatic winder because of the difficulty in processing and special technical requirements.

Now powerful enterprises, such as Jiangsu's Kay palace, Suzhou Wuzhong three spinning machine, Zhejiang Titan textile machinery and Shanghai plum blossom shaft, have invested huge manpower and material resources to develop and produce automatic winder.

In order to maintain market share, foreign enterprises take various restrictive measures to our textile machinery enterprises, so that some spinning machinery enterprises can not produce in batches.

For cotton textile enterprises, each slot can be replaced by a high price of 1500 yuan ~2000 yuan, which has become a huge expenditure for textile enterprises.

< /p >

< p > the success of the research and development of the automatic barrel winding machine is the way for the scientific research institutes to combine production, teaching, research and research. The implementation of scientific and technological innovation, the adoption of new technology, new materials and new technology, and the pformation of scientific research achievements into productive forces are important achievements. The project has successfully achieved the breakthrough of fully automatic domestic winder, which can reduce the cost of automatic winding machine and reduce the import of 10 million dollars per year, and has produced positive social benefits.

< /p >

< p > at present, domestic textile enterprises choose their own winder mainly from Italy, Japan, Murata, Germany and Qingdao Hongda Company.

Then, what is the pure domestic breed automatic winding machine introduced by Lu Lu to attract customers? Where is the selling point? < /p >

< p > "high cost performance!" Zhang Zhonghui said that they did not aim at the highest speed in designing, but rather emphasized practicality and stability as well as low failure rate.

Although the designed spinning speed is only 1000 m / min ~1200 M / min, it can completely meet the requirements of the present cotton spinning enterprises.

High speed is the ideal effect pursued by enterprises, but the speed is too high and sometimes brings many problems.

When the speed of the automatic winder is less than 1200 m / min, or the spinning of pure cotton combed 60 yarns, there is no problem in the domestic a href= "http://www.91se91.com/news/list.aspx ClassID=101112107108" > electronic clearer > /a >; if the speed reaches 1600 M / min, or spinning 80 or more Combed Yarns, the testing ability of the domestic electronic yarn clearer may be challenged.

Therefore, Zhang Zhonghui said that Luo Lu company's speed is positioned in both the domestic electronic yarn clearer and the cotton mill's conventional basic requirements for automatic winder.

< /p >

< p > "large enterprises with large capital strength generally do not choose domestic equipment.

Therefore, these enterprises are not our sales targets.

Our main market in the future is mid-level. The key is to face small and medium sized enterprises which are not abundant in capital, but have strong demand for automatic winding.

Zhang Zhonghui said they were not worried about sales.

At present, a large number of enterprises in China use the manual air splicer produced by their company. These customers are potential customers of their own winder.

< /p >

< p > < < a href= "http://www.91se91.com/news/list.aspx" ClassID=101112107105 > > textile machinery industry < /a >, almost any equipment has thirty or forty enterprises to set foot in, only automatic winding machine, 20 years later, can only mass produce only Qingdao Hongda family.

Therefore, whenever a reporter meets the R & D personnel of the automatic winder, he always asks, "is it difficult to develop automatic winder?" the answer is almost one word: hard! The same question, Zhang Zhonghui also gives the same answer: "difficult! And the more you know the concept, the more you understand its technological requirements, the more difficult it is, the harder it is, the more we want to do it better."

During more than a year's development, Dr. Luo Lu's technical staff and doctoral students from Tsinghua University and Donghua University, who participated in the research and development, have repeatedly tested and consulted the opinions of cotton spinning enterprises, and constantly improved various parts of the equipment.

They made many improvements just half a year after last year's Textile Expo.

For example, tension part, the equipment tension displayed on the exhibition is adjusted by spring. Now it has been adjusted to solenoid valve and controlled directly by computer.

The closed loop links are added to the slot drive, and the constant tension is maintained along with the speed of the grooved drum, so that the superposition of the yarn is greatly reduced, thus effectively improving the yarn quality.
