The invention provides circular loom magnetic shuttle power assistance unit, comprising the following solving scheme: the shuttle is settled in the orbit of a circle; the pushing bodies is connected with principal axis through handspikes; in the rump of the shuttle there are permanent-magnets which are fixed in the pushing bodies and the two poles of the permanent-magnets nearby are of the same homonymy; there is a nonmagnetic lead-thread frame is equipped outside of the shuttles and in the rump of the shuttle there is an aluminium alloy back bracket, and upon the back bracket there is a eccentric fixed wheel. The invention is simple in the structure, convenient to use, hard to see the phenomenon of silk breaking, improves the efficiency of loom, and suits for any type of looms. |
