Development trend of blowing and carding equipment

Author:Xinjinlong Machinery-Fabric Recycling Machine Manufacturer

Since 1960, consumer carding related equipment, after more than 40 years of development, especially since the 1990s, due to the combination of computer technology, sensing technology, frequency conversion technology and open elimination carding technology, carding is not only related to the realization of The combination of stand-alone and automation, and also realizes a precise automatic monitoring system, the blowing and carding is becoming mature, and it has become an advanced technology between continuous spinning processes, improving labor productivity, improving product quality, and reducing energy consumption to protect the environment. . During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. Special equipment for the textile industry on the winder.

As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field. Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame.

The blowing and carding technology presents the following development trends. 1. The research on breaking up the small opening shows that through the open arc treatment, the cotton flow, the gradual increase of neps and the short process help to reduce the neps of Cheng Kaiqing cotton, reduce the growth of short fibers, and improve the product quality. Give full play to the efficiency of each single workflow in the short-term Zheng Kaiqing cotton, so climb fine, free to fight, efficient cleaning, multi-warehouse integration, delicate opener and automatic cotton, and constantly improve the carding technology based on sound, Improve sliver yield and quality.

The opening and cleaning unit in the blowroom-carding unit completes the mixed opening and impurity removal task of the enterprise, while increasing the corresponding cost of neps and short staples; the carding machine removes a large number of neps and impurities under the action of impurity removal and carding, which will reduce The fibers are damaged to a certain extent, which increases the short pile. Therefore, there is a contradiction between eliminating these impurities and reducing neps and short staples in the blowing-carding process, which is an important research focus when processing raw cotton in modern blowing-carding processes in China. 2. In the past 50 years, the carding machine has high output and high speed, and the carding machine has developed in the direction of high speed and high output. The carding machine speed is 180r/min, and in the 1950s, it was 5kg/h. The output increased to the beginning of the 21st century, and the ceiling speed reached r/min, 450-600 cotton carding machine output increased to kg/h, 45-140, that is 2.5-3.3 times, the output increased 19-28 times.

Coiler production is 180kg, not much has changed in 50 years. From the point of view of blowroom and card technology, 50 years ago, the output of blowroom and card was 36 times that of the carding machine, and the unit output of the carding machine was very low. At present, with the successful development of the high-yield carding machine, the output is gradually approaching the blowdown output, the connection process is getting simpler and simpler, and the cleaning and carding problem that has not been completely solved has gradually diminished.

The development and application of new metal card clothing is the key to realize the high output and high speed of the carding machine. Different types of carding boards and fixed flats are used to increase the carding strength by expanding the carding area and raising the center of the cylinder. In recent years, the blowing and carding equipment at home and abroad has a trend of widening, which not only increases the output by increasing the speed, but also effectively guarantees the output and quality.

3. Online automatic monitoring and monitoring information technology can use various forms of autoleveling devices to effectively manage and control the weight of the sliver. (1) At the same time supporting new clothing, the maintenance of clothing is also very important. Modern state-of-the-art carding machines are equipped with pressure gauges and fine-tuning cap line automatic grinding systems, the flat setting is adjusted with high precision, and the carding elements remain sharp and maintain accurate needle condition.
