The invention relates to a gumming device for an amorphous alloy three-dimensional roll iron core. The gumming device comprises a base, a first adjustment screw, a second adjustment screw, four support plates and four auxiliary plates. Four support plates are respectively a left support plate, a right support plate, a front support plate and a rear support plate. Four auxiliary plates are respectively a left auxiliary plate, a right auxiliary plate, a front auxiliary plate and a rear auxiliary plate. The base is horizontally arranged. The first adjustment screw is longitudinally arranged on the base. The second adjustment screw is vertically arranged on the base. The left support plate, the right support plate, the front support plate and the rear support plate are vertically arranged respectively. The left support plate and the right support plate are arranged left and right on the first adjustment screw. By the gumming device, epoxy resin can be applied to the surface of the amorphous alloy three-dimensional roll iron core. The problems of low gumming efficiency and degraded performance in the prior art can be solved.
