The invention provides an opening and closing
magnetism adjusting structure permanent
magnet roller which comprises a
motor speed reducer, a driving chain wheel, a chain, a driven chain wheel, a fixing base, a
magnetism adjusting
handle, an end plate, a non-magnetic outer cylinder, an adjustable
magnetism roller and a support, the non-magnetic outer cylinder is fixed to the end plate in cooperation with a screw, and the driven chain wheel is fixed to the end plate through an auxiliary bolt. Compared with the prior art, the magnetic roller has the following beneficial effects that the magnetic roller is designed to be of a movable connecting rod structure, the permanent magnetic roller of the opening and closing magnetism adjusting structure can adjust the
magnetic field of the roller surface through rotation of the magnetism adjusting rotating shaft at the end, and therefore the function of rapidly and conveniently adjusting the
magnetic field is achieved, and a
magnetic separation production line can adjust
magnetic separation parameters according to actual conditions to obtain a better
magnetic separation effect; the equipment adjusting capacity is high, the magnetic
separation technology adaptability is good, meanwhile, for a user side, the permanent
magnet roller of the opening and closing magnetic adjusting structure can set various magnetic fields on the user site, one
machine can achieve multiple purposes, the inventory and the number of spare parts are greatly reduced, and the
purchase cost of the user is saved.
