As labor costs have risen, the labor costs of national textile enterprises are on the rise. To upgrade the traditional industries with modern and automated equipment and to promote technological bonuses instead of demographic dividend has become the inevitable choice for the optimization and upgrading of China's textile industry and sustained economic growth.
"Substitution of machines" is to upgrade the traditional industries with "modern and automated" equipment to achieve the goal of "downsizing, enhancing efficiency, improving quality and ensuring safety" so as to enhance the quality and level of enterprise development.
1 .automatic cotton mixer, and wool machine
With the development of spinning to multi - component and polychromatic fibers, how to mix all kinds of fibers (or colors) is an important prerequisite for spinning good yarns. The digital intelligent automatic mixer and wool human instead of artificial cotton blending (MAO) method can make the multi component (color) of raw materials to make full uniform mixing effect, and can reduce the labor of more than 2/3.
2 . Blowing-carding units
Blowingcarding is an advanced and mature technology, pure cotton and cotton yarn omitted transport workers, at the same time because without manual change lap, carding tenders can be expanded at more than 50% units, saving labor; with autoleveller can effectively control the comb sliver weight difference on carding machine, the uniformity is very favorable the yarn length to improve; after opening and cleaning after the cotton is always in the opening state of the feed carding machine, carding machine can not only improve the carding degree and reduce fiber damage, but also has a positive effect on reducing the card sliver neps.
3 .self leveling, automatic doffing machine
The drawing frame autoleveller technology, realizes the online automatic control, and at the same time, using a single technology in spinning cotton combed yarn, blended yarn can also be from the original three road and changed to two, due to reducing the number of drawing together, can save labor 1/2 ~ 1/3, and can reduce energy consumption. Automatic cylinder changing device and the frame, allowing the device to keep the state machine to automatically change the cylinder 3, the operator can be an hour apart for tube operation, not only reduces the labor intensity of workers, but also can expand the ability of the stands.
4 .Automatic doffing roving machine and thickness combination technology
The thickness of joint technology from roving machine automatic doffing roving through the sprocket transportation automatic control system directly transported to the creel of spinning machine, and the empty roving spinning machine used to roving machine spare tube. Not only can reduce the operator (employment is reduced by 50% or so), but also can reduce the defects of artificial doffing roving, improve the yarn quality.
5.Automatic doffing spinning machine and automatic doffing trolley
Spinning is the most spinning process of labor, collective automatic doffing spinning machine realizes the automation and intelligent operation, not only reduces the labor, but also effectively improve the production efficiency. Intelligent doffing trolley is aimed at conventional spinning machine is a new technology to reduce labor intensity, reduce the doffer, can save about 50% of the workers, and the transformation cost less, by the weak economy of small and medium-sized enterprises welcome.
6.Automatic winder and double twister
Tray type automatic winder automatic transport spinning tube feeding, automatic empty bobbin winding bobbin output, automatic transport etc.achieved automation intelligent operation, make the winding process of labor is greatly reduced, fully showing the superiority of machine substitutions. The high speed winding process and package twisting machine is omitted after twisting, winder can also save about 50%, and is conducive to improving the quality of yarn.
7. Intelligent on-line inspection and control equipment for different fiber
The different fiber in cotton is also called "three silk". In the process of spinning, if it can not be removed effectively, the quality of yarn and final product will be seriously affected. The application of digital imaging equipment to examine different control principle, in particular the light and clear not through the fiber detection light source, effective alternative method for picking cotton fibers, the machine generation, saving a lot of manpower.
8 .rotor spinning and swirl spinning
Compared with ring spinning, rotor spinning, air-jet vortex spinning and ring spinning have many advantages, such as short spinning process, high production efficiency, low labor consumption and low energy consumption, and the cost of work cost is 1000 yuan / ton lower than that of ring spinning.
In a word, we should increase the strength of the new spinning technology, accelerate the technological transformation and realize the purpose of "machine changing".
