Textile Machinery Exhibition: J 20, Murata NO870

this time

It should be a recent exhibition of innovative technology with more equipment, one of the J 20 jet spinning and the NO870 of Murata.

Competing for glory is one of the highlights of this exhibition.

Because Murata and Lida both focus on innovative companies, they avoid each other's technology in patents, thus creating completely different equipment concepts.

According to my observation, each has its own length. Lida's equipment has high technology content, and has adopted many innovative high technology.

In principle, there is no essential difference between the two. They all adopt the air jet twisting technology. The yarn style is the same, but in the process of spinning, the similarities between the two are very few.

Both of them developed their own traditional advantages, and Rida used their mature experience in rotor spinning technology. J20 looks more like an air-jet spinning concept with rotor spinning.

Murata followed the development route of the automatic winder, and adopted some technology of winder, and the whole machine was more like a roving frame.

Different ideas have different pros and cons.

Fuselage design: the equipment of Lida is more compact. Because the spinning route is from bottom to top, the cotton sliver can be placed under the body, with less floor area. The spinning route is short and the operation is convenient.

Murata's equipment adopts the concept of roving frame, and the sliver is introduced from the rear guide bar to the draft and nozzle.

Finally, the yarn is wound under the bottom, which covers a large area, and the operation is relatively complicated.

Draft device: both drafting devices are four rollers three area super large extension.

Connection device: the joint principle of each of the two has its own characteristics. Murata adopts air splicing technology, and Lida adopts the seamless joint technology similar to rotor spinning, and the design idea is very ingenious.

Winding device: in the winding technology, Lida adopts independent pmission with innovative technology, double disk winding device, winding speed is not affected by the length of the machine, and can greatly improve the winding speed of long cars.

In the winding technology, Murata's spinning tension stabilization system is undoubtedly a bright spot. Through this technology, Murata realized the conical drum winding.

In terms of machine flexibility, because of the independent pmission technology of J20, apart from the suction system, all spinning machines are relatively independent. In addition to the idea of double sided machine, a machine can produce two varieties at the same time, which is more convenient for high speed jet spinning machines to achieve fast, small variety and multi batch production.
