The development trend of foreign double-needle socks machine is from mechanical control to intelligent, automatic and high-speed development. There are many manufacturers of socks machines, mainly: Italy Matec, Japan Shimadzu, Italy Santoni. These companies are internationally leading in the design of the mechanical structure of the socks machine, the design of the flower pattern system and the control system of the socks machine. At present, these advanced socks machine manufacturers are concentrating on the development of small diameter, variable stitch length and high intelligence. High-speed full-computer double-needle socks machine.
At present, the most notable features of the technology development of high-performance double-cylinder computers are the following:
1. One-time forming and weaving new technology
Ordinary computer socks machine is formed by the "two-step method", that is, the socks formed by weaving need to be sutured under the machine. The latest double-cylinder computer-shaped sock machine adopts a one-time forming weaving technology, which changes the process of knitting the socks from the beginning of the sock to the end of the sock, and then suturing the sock. The fuselage is woven from the toe, and can form a bag-shaped closed sock, and finally weave the sock, thereby eliminating the process of sewing the toe, improving the production efficiency, and the knitting technique is woven. In terms of organization, it has also been simple to organize from the past to the current woven complex organization.
2. Active yarn feeding technology controlled by servo motor
The ordinary double-snake machine adopts the mechanical negative feeding technology. During the knitting process, especially during the elastic yarn feeding process, the tension of the feeding yarn is uneven, which leads to uneven knitting of the fabric. The performance of taking is reduced. The new double-cylinder computerized sock machine is equipped with a new constant tension yarn feeder. The yarn feeder adopts servo motor control technology, which can monitor the change of yarn tension in real time through the PID control system, thus making the elasticity of the feeding weaving system. The change in the tension of the yarn is controlled within an allowable range of fluctuations.
3, new pick, needle technology
The double-cylinder computer socks machine is equipped with a new type of pick and needle. The advanced model adopts multi-channel picking and picking needle technology. It adds an extra picking needle to the sock machine to achieve double picking or double picking. More picks and more, reduce the torque when knitting the toe socks during the weaving process, so as to achieve a smaller turning angle, higher speed, three-dimensional cotton socks can be woven on the basis of tissue design. Many high-end models use a special base to achieve less broken needles and zero broken needles.
4, multi-needle technology
Multi-needle technology is also the latest breakthrough in the technology of double-cylinder computerized sock machine. Through the operation control board of the computerized sock machine, the stitch length can be changed, the needle selection position and the number of stitches can be adjusted, so that the wide range of the woven sheet can be changed. Different effects are woven on the same woven piece, for example, the intarsia effect of different thicknesses of the same woven piece. The variable stitch length technology can meet the multi-purpose of one machine, which greatly improves the applicability of the variety of computer socks machine.
Foreign advanced socks machine manufacturers are still pioneers in the development and production of double-needle computer socks machines. They have advanced product design capabilities and research and development capabilities, and constantly improve the design of key parts to achieve greater market share.
