Electromagnetic needle selection mechanism for jacquard machine

Abstract

The invention relates to an electromagnetic needle selection mechanism for a jacquard machine. The electromagnetic needle selection mechanism comprises iron cores, magnetic conduction sleeves, moving iron, vertical hooks, preset springs, coil frames, coils and electrodes, wherein the coils are arranged in the coil frames; each coil frame is arranged on the corresponding iron core in a sleeving manner; each magnetic conduction sleeve is arranged on the corresponding coil frame in a sleeving manner; each magnetic conduction sleeve is arranged on the corresponding iron core in a sleeving manner; each moving iron is arranged on the corresponding iron core in a sleeving manner; each moving iron is provided with a limiting slot; each preset spring is positioned between each magnetic conduction sleeve and the corresponding moving iron; one end of each preset spring is positioned in the corresponding limiting slot; each vertical hook is provided with an elastic rubber claw; each elastic rubber claw is arranged on the corresponding moving iron in a clamping manner; each magnetic conduction sleeve is matched with the corresponding moving iron to each other; each electrode is communicated with the corresponding coil and fixed on the corresponding coil frame; each coil is arranged on the corresponding iron core in a sleeving manner. The electromagnetic needle selection mechanism is simple in structure, fewer in components, high in efficiency, good in stability, convenient to manufacture, low in maintenance cost, high in energy utilization rate of needles per unit, and good in integration degree.

Description

technical field [0001] The invention relates to a needle selection mechanism of an electronic jacquard machine, in particular to an electromagnetic needle selection mechanism of the electronic jacquard machine, which is used for the needle selection of the electronic jacquard machine. Background technique [0002] Jacquard machine needle selection is a relatively complicated process. The international research on electronic jacquard shedding mechanism began at the end of World War II. In the 1970s, due to the application and development of large-scale integrated circuits and electronic computers, research on electronic jacquard machines has achieved great progress. significant progress. In 1983, the first electronic jacquard machine was exhibited as a prototype at the Milan Textile Machinery Exhibition. Since then, many jacquard machine manufacturers have included it in their development plans. It can be said that since the 1980s, the textile industry has flourished and a hu...

Problems solved by technology

Compared with BONAS: the working principle is basically the same, but the complexity of the mechanism is different, and the mechanism of Staubli is more complicated

[0005] However, the existing electronic jacquard machine needle selection mechanism uses the principle of electromagnets to attract iron parts, so the volume of its mechanical parts is relatively large, making the number of needles per unit area small, thereby limiting the improvement of its efficiency
