The multi-magnetic-pole jack comprises an adjusting magnet and a fixed magnet, the adjusting magnet is movably connected to the axis of the fixed magnet, the adjusting magnet comprises a plurality of adjusting magnets and a plurality of adjusting magnetic conductive rings, and one adjusting magnet is arranged between every two adjacent adjusting magnetic conductive rings; the fixed magnet comprises a plurality of fixed magnet sets and a plurality of fixed magnetic conducting rings, one fixed magnet set is arranged between every two adjacent fixed magnetic conducting rings, when the S poles of the fixed magnetic conducting rings are aligned with the S poles of the adjusting magnetic conducting rings, the multi-magnetic-pole jack forms an external magnetic field to adsorb foreign objects, and when the S poles of the fixed magnetic conducting rings are aligned with the N poles of the adjusting magnetic conducting rings, the multi-magnetic-pole jack forms a magnetic field to adsorb the foreign objects. External magnetic fields of the multi-magnetic-pole jack counteract each other, so that foreign objects cannot be adsorbed. According to the multi-magnetic-pole jack, magnetic force can be better utilized, magnetic force waste is avoided, and magnetic adsorption work on sheet materials can be efficiently completed.
本发明公开一种多磁极起重器,包括调节磁体和固定磁体,调节磁体移动连接在固定磁体的轴线上,调节磁体包括多块调节磁铁和多块调节导磁环,相邻的两块调节导磁环之间设有一块调节磁铁,固定磁体包括多个固定磁铁组和多块固定导磁环,相邻的两块固定导磁环之间设有一个固定磁铁组,当固定导磁环的S极与调节导磁环的S极对齐时,多磁极起重器形成外部磁场进行外物的吸附,当固定导磁环的S极与调节导磁环的N极对齐时,多磁极起重器的外部磁场相互抵消,无法进行外物的吸附。本发明提供一种可以更好的利用磁力,避免磁力浪费,可以高效完成对薄片材料进行磁吸附工作的一种多磁极起重器。
