The Gap Of Domestic Equipment Is More Than &Nbsp, And The Reliability Is Poor.

At present, China's textile enterprises are in a critical period of pformation and upgrading. Many front-line users have placed great expectations on speeding up the pformation of textile machinery.

Wu Zhengang, general manager of Zhengzhou Hongye textile company, believes that the domestic spinning machine has many problems, such as low efficiency, large number of users and poor reliability.

Wang Enqing, the product design and Development Department of Nanshan Garments Co., Ltd., told reporters that the looms imported by Nanshan company are mainly imported equipment. From the point of view of usage, the imported equipment is more suitable for the actual needs of the company's product development.

Domestic textile machinery and equipment have certain price advantages, and the purchase of equipment and accessories is relatively convenient, but there are still some problems in terms of automation level, energy saving and consumption reduction.

Wu Zhengang emphasized the flexibility, mechatronics and modular structure design to develop textile equipment with differential functions and on-line detection, computer network diagnosis and automatic control functions, so as to realize the upgrading and upgrading of traditional textile machinery.

At the same time, Wu Zhengang pointed out that the textile machinery should be applied to popularize electromechanical materials with high strength and lightweight properties and energy saving, reduce energy consumption of textile machinery and equipment, and provide technical support for the overall energy conservation and consumption reduction of the textile industry.

Wang Shili, Minister of production of Yucheng cashmere company of Shandong Lu Yin group, said that similar to other semi worsted enterprises, Lu Yin's current production facilities are mainly cotton spinning equipment.

This situation is related to the unfinished semi worsted special equipment in China. In the actual production process, the technical personnel feel that the semi worsted carding machine, drawing frame, roving frame, spinning frame and other semi worsted production equipment still need to be greatly improved.

Semi worsted carding machine can be divided into two types: feed type and cotton box type. Two types of equipment have been optimized in feeding control and self levelling. However, there are still some shortcomings in the use of semi worsted carding machine.

First of all, both of them are not ideal in controlling the evenness of feeding wool. The feed quantity is greatly influenced by the raw material condition, which affects the overall weight irregularity.

Secondly, the self leveling control part is affected by feeding raw materials. The adjustment accuracy of self levelling is not ideal, the weight fluctuation is large, and the irregularity is high.

Carding machine is necessary to further improve in these two aspects.

At present, the drawing frame used by Yucheng cashmere company is simple in structure and suitable for cotton based varieties. But for the larger discreet varieties, the drafting parts are not very ideal for the fluffy varieties with larger fiber length distribution. Drafting wave or mechanical wave often exists in the Ulster dry spectrum, and this situation is difficult to achieve better condition through process adjustment.

Wang Shili thinks that the drafting structure of Italy SH four gill is worth drawing from the drawing mills. The drafting area of this draft structure is controlled by four rollers, and the control range of the fiber is relatively wide. The tension draft adjustment and the front septum adjustment of each part are very convenient.

Wang Shili added that through many years of efforts, domestic spinning machines have made great progress in Laura, but the stability of the whole machine needs to be strengthened. There is still a long way to go in the feasibility of mechatronics and automatic control components.

With the production of new semi finished worsted industries, the special domestic equipment needs to be perfected and improved through production practice. Enterprises hope that the textile machinery manufacturing enterprises can strengthen the research in the manufacturing accuracy, reliability, high-efficiency and automation of the equipment, only in this way can the textile enterprises achieve the long-term development trend of high yield, high efficiency, reliable quality and labor saving.
