Hengtian Yongan's leading products are high count, high-end cotton yarn, cellulose fiber blended yarn, polyester fiber blended yarn and functional blended yarn. At present, the second cotton factory produces 160 high-end yarns. Zhang Yadong said: "our product positioning is" high-end, high count ", mainly producing two series of products, compact spinning yarn and tight spinning yarn. At present, 250000 spindles of cotton spinning capacity, all the production of combed compact spinning (compact spinning) yarn, not the production of ordinary ring spinning yarn. The products are mainly used for clothing fabrics and high-end home textile fabrics, providing services for domestic and international high-end customers

Since this year, China's textile industry has suffered a serious impact from pneumonia, which has also brought great difficulties to HengAn textile industry. In the face of difficult situation, Hengtian Yongan firm confidence, broaden the market, rapid response, hard internal training, overcome difficulties. "Up to now, our No.1 Factory has been producing at full capacity, carrying out order production, paying before delivery, and maintaining the balance of production and sales and benign operation. The company's second plant is currently in trial production and plans to reach its production capacity by the end of the year. " Zhang Yadong said.

Zhang Yadong believes that Hengtian Yong'an has several advantages: first, the company implements mixed ownership, which brings standardized and efficient system advantages; second, the company has advanced equipment, all four spinning mills are intelligent chemical plants, and the equipment is national production, independent and controllable, and the production is intelligent and green; thirdly, the company has the advantages of mixed ownership The company has a learning technology management team, the staff team is relatively young, with team advantages.

Among them, the advanced equipment provides hardware guarantee for Hengtian Yongan to produce satisfied products. "Our first factory used 25 sets of Qingdao Grand vcro-e tray type automatic winder. After careful debugging, the stability and reliability of the equipment are good, the yarn quality is stable, and the production efficiency is stable above 85%. Our products have been widely recognized by downstream customers. Youngor, in particular, highly recognizes the yarn we produce, and we have always been a stable supplier. Because of its high efficiency, our second factory does not hesitate to continue to use 25 sets of Qingdao Grand vcro-e winders. "

Four advantages help to improve efficiency and reduce consumption

According to Zhang Yadong, in actual production, the advantages of Qingdao Hongda equipment are mainly reflected in four aspects.

Zhang Yadong, general manager of Hengtian Yongan

First, the yarn quality of the equipment is excellent. Winder is the last quality control process of spinning factory. The three key components of Qingdao Hongda winder, such as groove drum, twister and yarn cleaner, are all imported products of international brands. Advanced ideas are adopted in the design of yarn path, which can ensure good yarn index. At the same time, a number of advanced technologies are used to produce the same tension, uniform package density and excellent molding; moreover, it can be flexibly set according to different process requirements, which can fully meet the personalized needs of different users. Due to the excellent performance of vcro-e winder, at present, the process indexes of compact spinning 60 yarns produced by Hengtian Yongan are all kept within the level of 5% of Uster communique, and the broken ends per million meters of cylinder yarn are kept at the level of 0.173 (domestic high-level spinning enterprises generally keep within 0.2 ~ 0.6), which is in the leading position in the domestic market and has formed a good reputation.

Second, less labor and low energy consumption. The total labor cost of the whole winding machine is only 75.5% less than that of the automatic winding machine in the traditional winding machine. This is mainly due to the high degree of automation and stable operation of Qingdao Hongda vcro-e winder. Due to the reasonable process setting and the optimization of software by Qingdao Hongda, the success rate of one-time suction head of large suction nozzle can reach more than 96%, so the single spindle red light is rare. The car stopper only needs to push the yarn basket from the spinning yarn to the winder, and all the work is undertaken by the winder. After the doffing trolley doffing, the produced yarn is automatically transported to the tail of the machine to enter the automatic packing system, which can realize continuous production. The energy consumption of the winder is reduced by about 10% due to the use of multiple frequency conversion technology.

Third, high yield and high efficiency. Hengtian Yongan has put into operation 125000 spindles with an average yarn count of 65. The daily combed cotton yarn can reach 28 tons, and the production efficiency is stable at more than 85%.

Fourth, the equipment is stable and reliable. Qingdao Hongda vcro-e winder is reasonable in design, simple in structure and convenient in maintenance. Meanwhile, the quality of accessories has been fully verified on site. In addition to vulnerable parts, other accessories rarely need to be replaced and repaired, so it has high reliability and stability.

Targeted innovation meets individual needs

Compared with similar products at home and abroad, what are the unique features of Qingdao Grand equipment? From the perspective of technical innovation, Zhang Yadong believes that Qingdao Hongda vcro-e winder has designed an efficient intubation system. With CCD measurement and control technology, it can intelligently judge the size and diameter of the tube yarn. The single tube feeding capacity can reach more than 55 pieces / min (about 45 pieces / min for foreign equipment), which can meet the requirements of low count yarn for intubation speed. The yarn supply capacity of 72 spindles is 10% higher than that of imported equipment, which can realize the output Maximize. The intubation device has the function of discharging profiled yarn, which can discharge the empty tube and profiled yarn tube in advance, and indirectly improve the operation efficiency of the equipment. Intubation speed has adaptive function, which can improve the stability of intubation. Under the same circumstances, double cannula is widely used in foreign countries, which has complex structure and high maintenance cost.

In addition, the vcro-e winder has a brand-new tube yarn production station setting, which improves the efficiency of tube yarn production. Setting the waiting station between the pick-up station and the new head station can make the two movements of the pick-up and the first-hand work coordinate reasonably, reduce the waste of time and improve the efficiency of the head raising. The speed of single head production device increased from 20 to more than 24 per minute, reaching the international level.

Zhang Yadong believes that Qingdao's grand technological innovation provides users with high cost-effective equipment selection: the performance of vcro-e winder is close to that of imported automatic winder, which can help user enterprises improve product quality and production efficiency, reduce labor and power consumption, and reduce maintenance costs in the later stage, but the investment is lower than that of imported automatic winders.

Zhang Yadong also highly affirmed the service provided by Qingdao Hongda Company: "we are generally very satisfied with the pre-sale and after-sale service of Qingdao Hongda Company. The service engineers have high quality and strong skills, can respond quickly, meet our demand for after-sales service to the greatest extent, and often optimize and upgrade our equipment for free."

In addition, Qingdao Hongda's targeted innovation according to customer demand also meets the personalized needs of spinning enterprises. Zhang Yadong commented: "Qingdao Hongda can seriously listen to customers' opinions and improve rapidly. According to Hengtian Yongan's requirements, they have designed new structures, such as: trolley yarn clamping device, expert system type precision length determination, etc., to meet the personalized needs of our products.
