Faced with the high quality and high environmental protection requirements of international buyers for textiles, textile printing and dyeing enterprises can only meet their new demands by continuously upgrading their technological level and upgrading their machinery and equipment. The well-known home textile company, Joy Home Textiles, has recently carried out a full range of equipment upgrades, including the rolling mill transformation. Shanghai Xie Mante Electromechanical Equipment Co., Ltd. has transformed more than 20 old rolling cars for Joy Home Textiles, which not only makes the left, middle and right rolling ratio difference less than 2%, which makes it difficult for human vision to distinguish excellent and poor results. The rolling speed of the rolling car has increased by more than 10%, and the rolling rate has been reduced by 10 to 15%, which has significantly saved all kinds of energy and electricity consumption, and improved fabric quality and environmental protection. Recently, the Shanghai Association of the United States through the technical improvement of the main product association Mante uniform rolling, so that this series of products can achieve the printing and dyeing industry "old-for-new", can effectively save production costs and improve environmental protection for printing and dyeing enterprises.
Why does the company's uniform rolling mill series of products and technologies become the first choice for the transformation of equipment manufacturers? What are the advantages of the products? The reporter recently interviewed Jiang Xiaoyu, deputy general manager of Shanghai Xie Mante Electromechanical Co., Ltd.
The environmental protection advantages of rolling mill transformation are obvious
Reporter: Why does the Shanghai Union Mante Company develop a uniform rolling mill?
Jiang Xiaotong: Shanghai Union Mante Company is a long-established equipment integration and technical service enterprise, which was established by many well-known experts and enterprises in the printing and dyeing industry. At the beginning of the company's establishment, it has a clear goal: to achieve sustainable development and energy conservation and emission reduction in the printing and dyeing industry, to drive China's printing and dyeing technology to the international advanced level, in order to enhance the core competitiveness of China's textile enterprises. Especially in the field of ultra-wide-width uniform rolling, the technical level of domestic machinery can compete with international brands.
Uniform rolling has many advantages, and environmental protection and energy saving are the biggest advantages. The pretreatment effect of the process is good, the fiber damage is small, the quality of the treated fabric is high, and the hand feeling is soft, the dye color yield can be significantly improved, and the secondary adjustment caused by the chromatic aberration is reduced, thereby greatly reducing the burden of sewage treatment. Conducive to ecological and environmental protection, it also has the characteristics of high production efficiency, low labor intensity, water saving and power saving.
It is because of its environmental protection and energy-saving advantages. Many experts and technicians of Shanghai Union Mante Company have innovated and developed a new product based on the experience of the original Shanghai Printing and Dyeing Machinery Factory in designing and manufacturing the MH552 uniform rolling car for more than 30 years. —Xiemante has evenly rolled the car and has obtained national patents. The Commmann uniform rolling mill has horizontal, vertical and cross-rolling rolling mills, vertical rolling mills and medium-roller three-roll mills. The left, middle and right rolling ratios of the rolling mill rolls are all below 2%, which can fully meet the uniformity requirements of dyeing rolling mills. Among them, Xiemante's “High-efficiency rolling application and energy saving of the middle roller†was listed by the China Printing and Dyeing Industry Association as the fifth batch of advanced technology recommendation catalogues for energy saving and emission reduction.
At present, the domestic wide-width rolling mills generally have a current situation of uneven rolling liquid and high rolling ratio. In response to this situation, Joy Home Textiles Co., Ltd., Leyi Textile Group, Qingdao Phoenix Printing and Dyeing Co., Ltd., Shanghai Wanggang Hualun Printing and Dyeing Co., Ltd., etc. used to roll the rolling mill in front of the shaping machine, the mercerizing machine, the pad dyeing machine and the heavy rolling mill. The middle roller of the rolling mill before the sanding machine successfully reformed the old machine. Through the transformation of the rolling mill, the rolling efficiency can be effectively improved, the product quality can be improved, and significant energy saving and environmental protection effects can be obtained with a small investment.
In recent years, through continuous innovation and research and technological upgrading, Shanghai Xiemante has realized the localization of a variety of international advanced printing and dyeing equipment, and one of them is one of the roller mills. The middle roller is an effective rolling machine for improving the uniformity of the rolling mill and the efficiency of rolling, and can achieve significant energy saving effect with a small investment. The performance is at the top level in the world, especially the technology and service of the old machine transformation, which is rare at home and abroad.
Medium roll technology catches up with international
Reporter: At present, what is the market situation of the co-mantle uniform rolling car?
Jiang Xiaotong: With the increasing environmental protection pressure of printing and dyeing enterprises in recent years, enterprises have paid more and more attention to environmental protection work from the equipment link. The transformation of the rolling car is a key link, and it is also a link that is small in investment and quick in effect. Through the actual measurement, the rolling mill before the dryer, such as the medium-roller rolling mill instead of the ordinary rolling mill, the speed can be increased by more than 12%, the medium-thick fabric can be increased by more than 15%, the extra-wide fabric energy-saving effect more obvious.
The application of the Xiemente rolling car in the transformation of the old machine can effectively improve the speed and reduce the energy consumption, and the rolling rate is more uniform, which is very popular among enterprises. The company can design a variety of width and line pressure of the middle roller for special application in the process, such as the application of a wide-width non-woven fabric single-sided low-feed rolling process. At present, in addition to the transformation of more than 20 old rolling cars for Joyful Home Textiles, customers such as Shandong Eastern Europe, Huafang, Qingdao Phoenix, Nantong Lianfa and Fujian Futian are in further cooperation.
Reporter: What are the advantages of Xie Mante's uniform rolling?
Jiang Xiaotong: The co-mantle uniform rolling car adopts the fixed roller method, and the two bearings are placed inside the roller. The rolling cylinder pressure system is transmitted to the roller through the fixed roller and bearing, so that the bending of the roller surface is minimized, only 1/20 of the ordinary roller, no hydraulic compensation for the bending of the roller, left, middle and right rolling The rate difference is less than 2%, which can fully meet the uniformity requirements of dyeing rolling mills.
Energy conservation is the core competitiveness of the Commman uniform rolling mill. Compared with the MH552-320, the Co-Mart uniform rolling mill saves 5KW per hour and saves 30,000 kWh per year. Compared with the rolling rate of general rolling mills, it can be reduced by 10 to 15%, which is more energy-saving. Compared with the hydraulic uniform rolling mill, the frictional power consumption of the radial and axial sealing mechanism inside the hydraulic uniform roller is saved, and the energy consumption of the pumping station of the hydraulic system device is saved. In addition, the Comant uniform rolling car is easy to operate and easy to maintain. The unique rubber encapsulation method and formulation on the surface of the roll, as well as the uniform force of the various parts, make the rubber pressure control within the pressure range allowed by the rubber, and the service life of the ordinary roll rubber is longer.
The company's uniform rolling mill is divided into rolling mill, rolling mill and medium-roller three-roll mill, which can meet the requirements of modern production process in structure and design. The AMT551 two-roller vertical rolling mill is a equipment for flat-width rolling of pure cotton, chemical fiber and its blended fabrics. The roll pressure is large and can reach 400N/cm, and a more uniform rolling ratio. Make rolling mills more efficient. In the flat wide and continuous processing combined machine, several AMT551 two-roll vertical rolling mills are used to replace the original small rolling mill, which can effectively improve the washing effect and achieve the purpose of saving water and energy.
The three-roller medium-roller, which is developed and produced by Xiemante, is an innovative product with international advanced technology. The heavy-duty rolling mill using ordinary rolls, the structure of the rolls makes the pressure between the rolls larger, and the middle deflection of the rolls is also larger, resulting in the middle rolling not being dry and the rolling rate being large. The medium-roller rolling mill can effectively solve these problems. Through the special structure, technical performance and principle, the common phenomenon of the speed of the combined machine can be affected by the rolling of the wide-width heavy-duty rolling mill. By using the medium-roller to transform the large-diameter ordinary roll, the rolling rate can be reduced by more than 15%. Achieve the goal of less investment and significant energy saving.
Continuously improve to meet market demand
Reporter: What do you think about the future uniform rolling market?
Jiang Xiaotong: At present, energy conservation, environmental protection and high efficiency are the general trends in the development of rolling car technology. Rolling and rolling equipment at home and abroad is developing towards environmental protection, energy saving, time saving and high efficiency, and uniform and stable rolling rate. In the future, the research and development of Shanghai Xiemante will pay more attention to the efficiency of uniform rolling, and further optimize the process according to market demand, in order to achieve high efficiency, energy saving, environmental protection.
Reporter: What kind of development plan does the Shanghai Union Mante Company have in the future?
Jiang Xiaotong: Shanghai Union Mante Company will insist on doing fine and specialization in the field of uniform rolling. Only equipment that meets market demand has a future. We need to learn from foreign advanced technologies, increase independent innovation, continuously improve equipment quality, and combine the actual situation of domestic textile printing and dyeing enterprises to launch more suitable production for domestic enterprises. Printing and dyeing equipment for the situation. Through a point to provide assistance for the development of the industry, I hope to take the lead in the face, to make a positive role for the industry technology upgrades, equipment transformation.
On the other hand, for a company that develops technology, in order to survive in the market, it is necessary to give full play to the important role of intellectual property in the enterprise and effectively protect intellectual property rights in order to compete in the fierce market competition. Dominance. Otherwise, enterprises with independent intellectual property rights and continuous innovation are often eroded and dragged by counterfeit goods, so that normal market competition eventually degenerates into low-level competition of low quality, low price and ultra-low price. At the same time of research and development technology, the company will pay more attention to the protection of intellectual property rights to ensure the interests of users, while allowing developers to have a better environment for technological innovation.
