Details of the 2010 domestic spinning equipment market

Since the beginning of this year, cotton spinning companies have generally presented rare scenes of both production and sales in recent years. The spinning equipment market, which was severely affected by the financial crisis, also quickly recovered. The favorable market conditions also provided favorable conditions for the improvement of technology. Improve production efficiency, reduce labor, improve product quality, meet the innovation of yarn varieties and the requirements of small-batch, multi-variety production models. Saving energy and raw materials are users' main demands for spinning equipment. In response to changes in the demand of cotton spinning companies, spinning equipment manufacturers both at home and abroad have introduced new products, which are characterized by high efficiency, labor saving and stronger adaptability of varieties.

The collective doffing automatic doffing technology is maturing

Doffing is one of the most important production processes in the textile industry and the most labor-intensive. The use of collective doffing or automatic doffing not only drastically reduces doffing, but also greatly reduces labor intensity. At present, the technology of automatic doffing and collective doffing is becoming more and more mature, and it has been applied to roving machines, spinning machines and short cars. At the 2010 China International Textile Machinery Exhibition and ITMA Asia Exhibition held recently, the spinning doiplas were not only widely used by the captains of the spinning machines, but were also equipped with a collective doffing device on the short cars. Many companies such as Dongfei Mazuli and Shanxi Hujin have exhibited a short-haul model equipped with a collective doffing device. Dorset Global, Hebei Taihang, Tianjin Hongda and other companies have introduced automatic doffing roving machines. Among them, the CMT1801 intelligent roving doffer launched by Sci-Tech Universal is the latest generation of fully automatic doffing roving machine developed using the advanced synchronous control concept and combining the latest spinning mathematical model in the world. The machine adopts frequency conversion synchronous intelligent control system to achieve automatic doffing, minimizing labor costs. One person can operate up to 6 vehicles and reduce the number of operators by more than 50%. The doffing stop is completed in 120 seconds, which greatly improves the spinning efficiency.

In response to the demand for retrofitting of old machines by textile companies, Wuxi Focus Group Textile Machinery Co., Ltd. has developed the first fully-automatic doffing robot in China. The robot has the distinctive features of adapting new and old types of spinning machines, suitable for spinning all kinds of yarn, and adapting to various spinning companies. It utilizes a set of electronic-pneumatic-mechanical composite devices to simulate the action of manual yarn extraction and intubation, which realizes spindle-by-pull spinning and spindle-by-spindle intubation. It can also automatically detect small yarns and automatically avoid empty tubes. The model is simple and smart, accurate and reliable, and overcomes the problems of large system, complex mechanism, and high cost of the collective doffing device. It can not only be combined with the existing new spinning machines at home and abroad to form a full-automatic doffing spinning machine, but also Various types of traditional spinning machines are upgraded. This fully automatic doffing robot made its debut at this year's textile machinery exhibition and received a contract for 40,000 spindles.
