Qingdao'S Two Great Inventions Have Been Internationally Patented.

　　 Recently, Qingdao Hongda Textile Machinery Co., Ltd. came to the good news. The invention patent of two automatic winding machines of the company was authorized by Italy.

As we all know, for a long time, automatic winder technology has been monopolized by European and Japanese enterprises. As an outstanding representative of national brands, Qingdao Hongda has been committed to technological breakthroughs in automatic winder and breaking international monopoly.

For centralized yarn type pallet type automatic winding machine, intubation speed is one of the bottlenecks restricting the output of winder, especially when spinning low count yarn. In order to improve the speed of intubation, foreign counterparts have developed dual intubation mechanisms, which are complex in structure, difficult to maintain and have corresponding patent protection. Qingdao Hongda Company has made great efforts to study and invented an efficient intubation device. The intubation speed of the device is increased by more than 50% than that of the existing intubation mechanism, and the single mechanism can reach 55 / min. compared with the double pipe, the device has simpler structure and lower failure rate, and can fully meet the requirement of the number of 72 spun low count yarn to the number of tube yarn. Once the technology was launched, it gained high attention from peers and customers' affirmation. Now, after three years of approval process, the technology has finally obtained the European patent authorization. Its significance lies not only in the recognition of the technology, but also in the Qingdao Hongda Company's breakthrough in the key technology of the automatic winder.

The highly efficient intubation technology with international patents is applied to the latest generation of VCRO series automatic winding machine developed by Qingdao Hongda. The model is highly intelligent, efficient and reliable, and has adopted a number of advanced technologies. It has nearly 20 patents: the single pipe installation has the world's leading level of supply capability; the intelligent tube yarn supply and flexible tube vibration system ensure the smoothness and continuity of the yarn supply; the non-contact visual inspection technology is used to detect the abnormal yarn contour. Discharge decision, effectively improve the efficiency of the head; efficient head device and removal of the tail yarn device, improve the success rate of the tube yarn, and can configure a number of sets of head mechanism, to meet the high demand of customers to meet the maximum demand. The device can greatly reduce the accumulation of CBF waste and reduce the workload of maintenance. The model has now launched more than 100 sets, distributed around the country and abroad, and has been well received by customers. Many customers bought it and bought it again.

　　 Innovation is the soul of a nation, and it is also the way for an enterprise to survive. In recent years, Qingdao Hongda Company has continuously increased its investment in innovation and built a state-level technology center, focusing on training top talents in the industry, strengthening basic technology research, and building high-end USTER cotton spinning technology laboratory. At present, the company's technology research and development team has more than 70 people, and has more than 110 effective patents.

Shouldering the heavy responsibility of strengthening the national brand, Qingdao Hong Da will always strive on the road of "innovation".
