Wu Yigui: Performance Optimization Of Cotton Comber

With the rapid development of the individuation and quality of textile products, the quality requirements of the downstream enterprises of cotton textile have improved. Due to cost and other factors, cotton textile enterprises will consider making some scientific and reasonable adjustment in raw material blending with cotton spinning. Therefore, Zhejiang Jinfeng Textile Machinery Co., Ltd. has developed the JZX - "5" comb, sawtooth combined high efficiency comber comb.

however Carding fiber It needs a certain combing force, and the combing force is not enough, which will cause the bundles of fibers not to open, resulting in fiber bundles. If the carding force is too large, it will lead to fiber damage, increase the short linen, aggravate the abrasion of the needle teeth, even break the needle and break the teeth, and increase the energy consumption of the equipment. Therefore, the design of circular needles and sawtooth has been greatly improved. Round comb needle It is necessary to ensure the sharpness and roughness of the front end as well as ensure the taper of the rear end. Saw tooth slice The technology of stamping and grinding on both sides of the tooth surface ensures the smooth tooth tip, tooth root and tooth surface.

At the same time, in order to adapt to the high speed and large quantitative process requirements, avoid inserting, loosening and finishing of the front row sawtooth puncture cotton layer, and better integrate the advantages of the needle cylinder and the sawtooth cylinder to ensure the best puncture effect. The needle tooth height of the needle bar and the tooth piece is deep and shallow in the front row, which reduces the filling of the fiber to the cylinder and improves the carding effect of the fiber and cylinder. Such a cylinder design has consciously divided the tin forest into two regions, ensuring the carding quality of high-speed movement, and also suitable for various types of cotton comber mainframe.

With the increasing demand for semi finished products and yarn in cotton textile enterprises, how to meet the requirements of users and improve the quality and quality of products is a systematic project. Zhejiang Jinfeng should further improve the quality management network, strengthen the quality control points of the production process, and do well in the production.

Machine picked cotton is a way of picking cotton with mechanical equipment. With the continuous promotion of the production mode of machine picked cotton in Xinjiang, on the one hand, the shortage of labor resources in the flower picking period has been effectively alleviated, and on the other hand, the cost of raw cotton production has been significantly reduced. According to experts estimates, the average picking cost of long staple cotton is 3 yuan / kg ~3.5 yuan / kg, while the machine picked cotton is about 0.6 yuan / kg ~0.8 yuan / kg. The cost advantage of machine picked cotton is obvious, which has created favorable conditions for enterprises to enhance their market competitiveness.

However, the machine picked cotton in Xinjiang is different from the machine picked cotton abroad. Influenced by many factors such as maturity and equipment conditions, the quality of raw cotton is not satisfactory. Especially, the unfavorable factors such as high impurity rate, high short staple rate, poor uniformity and low strength make it difficult for later cotton embossing and pre spinning. By comparing the performance of machine picked cotton and hand picked cotton, the results show that the impurities in machine picked cotton are fragile, small and more difficult to remove. After repeated cleaning, the raw cotton content is generally 2.5% or higher, while hand picking cotton is generally around 1.5%.

In view of this situation, as a domestic champion enterprise of combing equipment industry, Jinlun card clothing has been committed to the research on the characteristics and carding performance of machine picked cotton in recent years, and has made great breakthroughs. A series of card clothing products and carding solutions that are suitable for machine picked cotton characteristics have been launched by Jinlun card clothing, which has contributed to improving the quality level and creating greater economic benefits for textile enterprises.

In the carding process, the main function of the cotton picker is to open the pine, and the smaller the cotton bundle is, the better it will be. The following processes are mainly considered: the running efficiency is above 85%, the running efficiency is high, the opening effect is good, and the mixing effect is obvious; the running speed of the trolley and the proper increase of running speed are favorable for mixing; the distance between the blade extending the ribs is the positive spacing or the negative spacer; the control of the descent process; and whether the blade and ribs are abnormal.
