Do you know what the knitting method of Pattern Braided Sleeve is?

The wire and cable industry is a basic industry in my country. For many years, the average annual growth rate of the wire and cable industry in my country has reached more than 15%, which has already exceeded that of foreign countries; as a matching product of wire and cable, Pattern Braided Sleeve are also growing.

In response to these problems, many Pattern Braided Sleeve manufacturers have different requirements for the industry in which the Pattern Braided Sleeve are used and the corresponding performance requirements, from the selection of raw materials, knitting equipment maintenance and the wire tension sensor in the knitting process, etc., and have developed new Pattern Braided Sleeve with light weight, good softness, good heat resistance, high compressive strength, high knitting density, and can meet the requirements of different industries.

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

There are two protective pads under the pitch gear of the goose-falling braiding. There is a deviation during braiding. It is renovated to reduce the relative height of the protective pad at this point and add a protective pad, thereby improving the gear meshing, ensuring the control of the pitch diameter, and improving the support force of the take-up, and improving the consistency of the telescopic angular velocity.

Material selection In order to better achieve the effect of anti-electromagnetic leakage or anti-interference of the Pattern Braided Sleeve, while achieving weldability, flexibility, light weight, anti-oxidation, heat resistance and high toughness performance indicators, 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 processing and 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 wire drawing shaft, and a single twisting machine specially designed for wire drawing is used for wire drawing. At the same time, the wire drawing machine fixture is changed to a fixture that can install 48 spindles of wire tubes, the wire drawing stroke is adjusted, and the wire drawing pitch diameter is changed again. This method can make the wire drawing support uniform and uniform without "wire pressing".

According to the production speed of the Pattern Braided Sleeve, the wire drawing brake pad is appropriately adjusted to keep the wire drawing speed ratio consistent with the pitch diameter 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 tear, 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 an "empty tube shape" and will not be compressed into a "flat shape" after the line is arranged, which is very beneficial to the sleeved cable.
