Abstract
The invention relates to the technical field of weaving machinery, in particular to a needle selection device which comprises a needle selection framework and a circuit board, wherein a plurality of electromagnetic needle selection devices are arranged in the needle selection framework. Each electromagnetic needle selection device comprises an electromagnet assembly and a needle selection sheet, wherein an iron core capable of attracting the needle selection sheet after being magnetized is arranged in the electromagnet assembly in penetrating mode. The needle selection sheet is movably arranged in the lower end of the needle selection framework, a positioning plate is covered at the bottom of the needle selection framework, the needle selection sheet extends to penetrate through the positioning plate, and the circuit board is arranged at the top of the needle selection framework. The electromagnet assembly generates a magnetic field after being electrified so as to enable the iron core to generate magnetic force to attract the needle selection sheet to swing, the magnetic field disappears in outage, the needle selection sheet resets, and accordingly, the needle selection function is achieved. The electromagnet enables the needle selection sheet to swing in high-frequency mode so as to achieve the needle selection function of the needle selection sheet, and the needle selection device can achieve high-frequency, high-load and high-speed working under high-pressure state, and is stable in using performance, simple and reasonable in structure, low in cost and convenient to process and assemble.
