In order to meet the market demand and improve yarn quality, Fu Teng Textile Co., Ltd. has invested more and more in technology transformation. In February 2012 and January 2013, 2 sets of HC500 comber were purchased (14 sets). From the recent use, HC500 comber has good adaptability to high speed and raw material modification, stable mechanical performance, advanced technology performance, and can improve production efficiency and reduce. Low production cost plays a certain role in improving yarn quality and enhancing the competitiveness of enterprises. It breaks the traditional idea that it does not require small flat cars, but only needs normal maintenance. Operators can directly participate in general equipment maintenance, laying a solid foundation for the lean management of equipment.

HC500 comber adapt to high speed

HC500 comber is a comber with high efficiency and energy saving. It has long service life and low maintenance strength. All kinds of self stopping devices are sensitive and effective, with fewer failures and fewer losses. It uses computer aided (simulation) optimization technology for dynamic analysis and optimal design of combing process parameters. Under the premise of higher production, load reduction, quality improvement, loss reduction, machine life extension and energy consumption reduction of individual components are achieved. The position of the cotton roller is moved forward relative to the position of the nipper jaw, which shortens the distance between separating the jaws from the rollers in the process of separating drafting, and reducing the number of floating fibers, so as to reduce the number of fibers blocked by the top comb and reduce the combed noil in the carding process. The structural size of the rear part of the lower jaw plate is changed, that is, the thickness of the lower clamp plate of the front part of the cotton roller is heightened. When the clamp plate opening is opened, the cotton layer which is carded by the cylinder is lifted up in time, which is beneficial to improving the bonding quality of the new and old cotton bushes and reducing Combing Noil.

Saving investment and maintenance cost

Due to the shortage of cotton resources, the quality of combed sliver has been relatively stable even though the cotton blending is relatively frequent when spinning the JC11.7 compact spinning line. According to practice, we found that HC500 comber has strong adaptability to raw cotton.

At present, Fu Teng textile company adopts 4 grade Australian cotton 60%, 3 grade Xinjiang cotton 40%, the average length is 29.5 millimeters, the micron value is 4.3, the impurity rate is 2.2%, 16 mm below the short pile content is 17%. Under this process configuration, the combed cotton web produced by HC500 comber is clear and consistent, and the eye rate is small. It can generally be controlled within 1.6%.

Through two years of practice, we found that the HC500 comber has the advantages of saving investment, reducing production costs and saving maintenance costs. For example, the output of HC500 comber is 3.5 times that of ordinary comber. According to 3 times calculation, under the same capacity condition, it can save an area of 800 square meters, save 900 thousand yuan for basic investment, save about 3 million yuan for equipment investment, and save about 3 million 600 thousand yuan on fixed assets investment. Under the same capacity condition, 6 workers can be saved (according to 3 classes). According to the saving of electricity per ton of 7%~10%, the electricity consumption can be saved by about 45 kwh / HR, and the annual labor cost and electricity charge will be about 430 thousand yuan.
