| As everyone knows, the volume of imports in China knitting equipment for several years maintained a higher amount, quantity of imports of circular knitting machine, computer automatic flat knitting machine and the seamless underwear knitting machine are relatively large. This aspect is of great interest to reflect the Chinese knitting industry rapid development brings, on the other hand, reflects the domestic knitting machinery still needs to continue its efforts in product efficiency, stability etc.. This background is reflected in the current exhibition, is knitting machinery and equipment accounted for 2 of the area of the display hall, home and abroad knitting machinery manufacturing enterprises participating enthusiasm rising. At the same time, a more obvious phenomenon is, knitting equipment to high precision, high mechanical electrical integration has been further improved.|
Foreign equipment leading edge technology
This exhibition abroad knitting equipment manufacturing enterprises and the exhibition of new knitting machinery are not many, many foreign enterprises display models are sold in Chinese market products for a period of time. Belonging to the Italy Rhone Group SANGIACOMO company is the display of the star and HT6 types of hosiery machine, do not belong to a new type. But even so, there are still displayed part of foreign enterprise will be a fusion of the company to the latest technology products, thus becoming the knitting Pavilion in the exhibition boutique.
The first is Meyer & west company exhibited BASICli - neSF4-3.2 type three wire fleece knitting machine. The models are Meyer & West Ltd BASICline series models in the latest model, processing for a variety of knitted velvet and 4 needle fabric. The machine with the help of the central height settings and through the vertical loop forming accurate adjustment, further realize the fabric thickness adjustment range widening. In addition, Mayer Si has developed a special pad yarn feeding technology, make the machine in the processing of thin elastic cloth and also can ensure the quality of the products. Knitting machine SF4-3.2 per inch 3.2 road yarn, production speed of 1.4 m / s, the tube diameter is 30 inches at the speed of 35 rpm. A staff member of the booth explained: a number of technology which models have world leading level, not only embodies the efficiency of machine and precision, but also reflects the flexibility of the machine.
In addition to the BASIClineSF4-3.2 type knitting machine, Mayer Si also introduced the Relaint1.6R type circular machine. It can be equipped with 12 tone line device, can also use the elastic yarn weaving. The machine is the most attractive place, is the needle distance range reached 28 needle. An expert evaluation said, the current round machine needle distance range in the 24 general needle within the circular machine, 28 pin represents the most advanced level of the present circular machine.
In addition, Siemens company for the development of the circular knitting machine is a specialized electronic jacquard control system Sitex, has become a lot of the focus of attention of the visitors. The Sitex system includes a SitexCK controller, man-machine interface of HMI, the needle selecting device SitexM, power SitexS and multiple varieties of knitted pattern. Among them, the piezoelectric ceramic needle selector is controlled by the SitexM pin, adopted the "Shun domain" piezoelectric technology, compared with the mechanical needle has the advantages of long service life, low noise and energy consumption; controller SitexCK can accept multiple format pattern files, moving through the needle selecting device precision control enable needle and syringe carrier complete synchronization. Siemens company staff said, Sitex provides a complete solution for electronic needle selection to achieve circular knitting machine.
In addition, like Japan Shima Seiki manufacturing display of computer automatic flat knitting machine, Germany Stoll multi stitch knitting machine, also reflects the new progress of knitting machinery to adopt new technology acquired. These are still the domestic enterprises need to intensify efforts to place.
The level of domestic equipment improvement
It is worth mentioning that, 28 pin round machine technology is not only a master of Meyer & West Ltd. Has a domestic enterprises have developed 28 needle knitting machine. Shanghai turtle step Machinery Equipment Co., Ltd. after 3 years of research, at the beginning of this year, overcome a series of technical problems of 28 needle knitting machine, become a breakthrough progress China knitting equipment field.
Because of fears of leakage of 28 needle technology, Shanghai turtle step mechanical equipment Co. Ltd. and did not have to be brought to the exhibition scene prototype. But the positive significance of domestic enterprises to overcome one of the most cutting-edge technology in the world is not so affected. 28 needle knitting machine turtle step machinery company represents the new progress of domestic knitting equipment made by.
The concave convex Pml Precision Mechanism Ltd exhibited a variety of knitting machinery products. Among them, double sided computer jacquard shift ring seamless machine is one of the key exhibitors products of the company. According to company sales department manager Yu Jianhua introduced, the machine of the hanging wall, lower ring adopts electronic needle selection, at the same time with the jacquard and loop transfer function, including 2 road configuration hanging wall moved circle triangle, 4 road configuration ring ring shift triangle; machine plus automatic modulating function and computer controlled speed batching function, servo pressure needle device and pressure contraposition mediation, in order to achieve a full electronic control. The machine reaches a maximum speed of 30 rpm, the WAC control system can be selected at the same time the needle in the hanging wall of the lower ring system and rolling machine, can according to different fabrics using 4 kinds of variable speed, by servomotors device independent tension cloth machine. Experts said, the machine realizes the application of electronic control loop transfer technology, embodies the machinery in the electronic control technology progress.
The precision and the electronic control technology of knitting machinery has always been the Achilles heel of domestic knitting machinery. The new models wellknit machinery show domestic machinery to conquer the problem determination. In addition, the improved AS - GE653 series multi function computer cross Suzhou three new spinning electromechanical Co. Ltd. knitting machine in the control software is also reflected in the situation.
