【摘要】：21世纪以来,我国转杯纺技术发展迅速,转杯纺设备适纺纤维范围不断扩大,转杯纺产品用途也遍及多个行业。据统计,我国现有转杯纺纱机规模超过300万头,约占全球转杯纺设备总量的1/3,转杯纱占我国纱线总产量的比值逐渐增大,转杯纺纱逐渐成为纺纱产业的重要组成部分。但目前国产的转杯纺设备仍以半自动转杯纺纱机为主,在自动、高速和智能方面的技术水平与国际先进水平相比仍有差距,对纺纱元件的新材料、新工艺、新技术的研发程度不高。在这种背景下,通过对转杯纺专利的检索与分析,了解国内外转杯纺技术的布局和研究现状,并分析中国转杯纺技术的发展趋势。本文以转杯纺专利作为研究的出发点,先对国家知识产权局、美国专利商标局和欧洲专利局三个专利数据库中的转杯纺专利进行检索,获得用于研究分析的转杯纺专利数据库。进而利用三大专利局中的转杯纺专利数据,从专利申请趋势、专利授权趋势、主要专利权人、专利被引情况等角度进行定量研究,发现国外转杯纺技术研究趋于成熟,目前我国转杯纺正处于技术成长期,但技术发展迅速,具有较大发展空间,值得深入研究。其次,基于国内外转杯纺专利文献,对转杯纺纱机按照机构予以分类。从专利数量、专利类型和专利内容三个方面对纺纱器、轴承和接头进行国内外的对比分析。结果表明我国在纺纱器和轴承方面与国外的专利技术差距较小,但在接头技术上的差距较为明显,主要表现为自动化程度较低和接头质量仍有差异,应加强对接头技术的研发。然后,以接头为主要技术内容,从接头机械设备、接头动作和时间控制两个方面入手,将国内外的转杯纺接头技术进行对比研究,分析中国转杯纺接头技术的可行发展轨迹。认为转杯纺接头技术的发展趋势是发展具有中国特色的全自动和半自动接头技术相结合的单锭单控模式的接头设备。同时也可发展全自动接头技术,实现接头各部件的动作和启动时间差的连续控制,实时监测和反馈调节技术的研发及纱线质量控制等。最后,转杯纺其他技术领域中,纺纱器的发展趋势是加工工艺和材质的优化、部件结构的改进并开发新材料;同时朝着多喂给、多分梳的发展方向不断创新。在轴承方面主要研发非接触式轴承及高转速下散热问题的解决。转杯纺产品从纯纺到混纺纱、花式纱的转变,产品用途向功能性方向开发。
[Abstract]:Since the 21st century, the technology of rotor spinning has developed rapidly in our country. According to statistics, there are more than 3 million rotor spinning machines in China, accounting for about 1 / 3 of the total rotor spinning equipment in the world. The ratio of rotor spinning to total yarn output in China is gradually increasing, and rotor spinning has gradually become an important part of spinning industry. However, at present, the domestic rotor spinning equipment is still mainly semi-automatic rotor spinning, and the technical level of automatic, high-speed and intelligent spinning is still far from that of the international advanced level. The level of research and development of new technology is not high. Under this background, through the retrieval and analysis of rotor spinning patent, the layout and research status of rotor spinning technology at home and abroad are understood, and the development trend of rotor spinning technology in China is analyzed. In this paper, the patent of rotor spinning is used as the starting point of the research. Firstly, the patent database of rotor spinning in three patent databases of the National intellectual property Office, the United States Patent and Trademark Office and the European Patent Office is searched, and the database of rotor spinning patent used for research and analysis is obtained. Then, using the patent data of the three patent offices, from the point of view of patent application trend, patent authorization trend, main patentee, patent citation, it is found that the research on rotor spinning technology abroad tends to be mature. At present, the rotor spinning in China is in the technical growth period, but the technology develops rapidly, has the big development space, and is worthy of further study. Secondly, based on the patent documents of rotor spinning at home and abroad, the rotor spinning machine is classified according to the mechanism. This paper makes a comparative analysis of spinning machine, bearing and joint from three aspects of patent quantity, patent type and patent content. The results show that the gap between China and foreign patent technology in spinning and bearing is small, but the gap in joint technology is obvious, which mainly shows that the degree of automation is lower and the quality of joint is still different, so the research and development of joint technology should be strengthened. Then, taking the joint as the main technical content, starting with the joint mechanical equipment, joint action and time control, the domestic and foreign rotor spinning joint technology is comparatively studied, and the feasible development track of the Chinese rotor spinning joint technology is analyzed. It is considered that the development trend of rotor spinning joint technology is to develop the single ingot and single control joint equipment with Chinese characteristics, which combines automatic and semi-automatic joint technology. At the same time, the automatic joint technology can be developed to realize the continuous control of the action and start time difference of each component of the joint, the research and development of real-time monitoring and feedback adjustment technology and yarn quality control, etc. Finally, in other technical fields of rotor spinning, the development trend of spinning is the optimization of processing technology and material, the improvement of component structure and the development of new materials. In bearing research and development of non-contact bearing and high-speed heat-dissipation problem. Rotor spinning products from pure to blended yarn, fancy yarn transformation, product use to functional development.
