Weaving method of Pattern Braided Sleeve

With the rapid development of modern electronic information technology, the problem of magnetic induction leakage and interference has become increasingly prominent. The Pattern Braided Sleeve mainly has the function of mechanical protection and interference signal shielding. The Pattern Braided Sleeve is laid on the surface of the cable, which is a shielding protection to prevent magnetic induction leakage and interference. It is also an important protection method to prevent the communication system from being paralyzed by nuclear magnetic resonance suppression in future wars. Different uses have many other requirements for Pattern Braided Sleeve, such as; weldability, heat resistance, anti-oxidation, conductivity, flame retardant Pattern Braided Sleeve, good shielding performance, light weight, low cost and other issues.

For these problems, many Pattern Braided Sleeve manufacturers have set requirements for the industry and corresponding performance of Pattern Braided Sleeve, from material selection, weaving equipment maintenance and wire tension sensor in the weaving process, and developed new Pattern Braided Sleeve with light weight, good softness, good heat resistance, high compressive strength, high weaving density, which can meet the requirements of different uses.

There are currently two types of fast knitting machines in my country. One is the drop-into knitting method. The drop-into structure is relatively complicated, and the oil stains at each part position are easy to pollute the product. The advantage is that the knitting speed is fast, but the yield rate is low; the other is the goose-falling knitting method. Each part is arranged under the spindle to avoid the pollution of kitchen fumes. The speed is almost the same as vertical knitting. At present, the knitting machines developed by my country itself can basically achieve production.

Material selection In order to better achieve the effect of electromagnetic wave leakage or anti-interference of the Pattern Braided Sleeve, while achieving the performance indicators of weldability, flexibility, light weight, anti-oxidation, heat resistance and high toughness, Huiyunhai Technology uses tinned copper core wire, nickel-plated copper core wire, tinned alloy copper wire and tinned copper clad steel wire and specifies the corresponding wire diameters of 0.1mm and 0.12mm respectively. Compared with the previous process, the wire is thinner.

The reduction of wire diameter during the development process has put forward better requirements for the weaving process. Because the wire material is relatively thin, it is easy to cause wire breakage during the weaving process. The wire drawing shaft is changed to a winding reel, and a single twisting machine special for wire drawing is used to pay out the wire. At the same time, the wire drawing machine fixture is changed to a fixture that can install 48 spindle wire tubes, the wire drawing stroke is adjusted, and the wire drawing pitch is adjusted again. This method can make the wire drawing support balanced and consistent without "wire pressing".

According to the Pattern Braided Sleeve production speed, the wire drawing brake pad is appropriately adjusted to keep the wire drawing speed ratio consistent with the pitch gear speed ratio. In order to better ensure that the new Pattern Braided Sleeve is more conducive to the sleeved cable, the friction of the brake pad is reduced at the take-up rotating gear to reduce the take-up support force as much as possible, which can ensure that the take-up support force is small and the product is not easy to break, which is beneficial to the high wire breakage rate during the weaving process and cause unnecessary waste. The new Pattern Braided Sleeve woven by this method is in the shape of an "empty cylinder" and will not be compressed into a "flat shape" after the line is arranged, which is very beneficial to the sleeved cable.
