Problems solved by technology

[0003] At present, the electromagnets used have the following defects: First, the electromagnet adopts a U-shaped iron core, a single coil, and a structure in which the armature swings around the axis after the coil is energized, which consumes a lot of energy, increases the temperature, and has poor thermal stability.
Secondly, the structural form of U-shaped iron core, single coil and armature swinging around the shaft cannot greatly increase the operating frequency of the electromagnet.
[0004] The above-mentioned problems affect the improvement of production efficiency and loom capacity. At the same time, the poor thermal stability of the electromagnet also affects the improvement of fabric quality.

Abstract

The invention discloses an electromagnet used for an electronic multi-arm reading mechanism. The electromagnet comprises a hollow electromagnetic coil, a permanent magnet and a movable iron core which is arranged in the hollow electromagnetic coil in a swingable manner, wherein the permanent magnet is arranged on the outer wall of the hollow electromagnetic coil and is positioned on the swinging plane of the movable iron core. The electromagnet is sensitive in action and quick in dynamic response, the action frequency of the electromagnet can be improved, the power weight ratio of the electromagnet is large, and the work heat stability is improved.

Description

technical field [0001] The invention relates to an electromagnet, in particular to an electromagnet used in an electronic multi-arm reading mechanism. Background technique [0002] The electronic dobby is one of the three major opening devices of the mechatronic loom. A part of the weaving signal of the loom fabric is processed by the computer in real time and becomes a heald signal, which is added to the electromagnet electromagnetic coil of the electronic dobby reading mechanism. The electromagnetic force generated by the iron is converted into the swing action of the moving iron core to drive other transmission mechanisms to lift the heald frame of the loom, and finally realize the opening of the warp yarn of the loom and the weaving of patterns. [0003] At present, the electromagnets used have the following defects: first, the electromagnet adopts a U-shaped iron core, a single coil, and a structure in which the armature swings around the axis after the coil is energize...
