Wherein the feeding step is as follows: the jacking mechanism jacks a stack of zinc sheets to a proper position, and the push plate pushes part of the zinc sheets from the side surface, so that the stack of zinc sheets transversely move to enter the electric furnace; the disadvantage of this feeding method is that when a stack of zinc sheets is pushed laterally, the zinc sheets below and tightly attached to the stack of zinc sheets are also easily pushed, resulting in the remaining zinc sheets on the jacking mechanism becoming loose, sometimes affecting the smooth feeding process.

On the other hand, the cross section of the processed zinc ingot is in an isosceles trapezoid shape, one of the upper surface and the lower surface of the zinc ingot is a wide surface, and the other surface of the zinc ingot is a narrow surface; when stacking zinc ingots, one zinc ingot stack is provided with the zinc ingots with upward wide surfaces and also provided with the zinc ingots with downward wide surfaces; in order to realize automatic stacking of the manipulator, the manipulator is provided with a clamp capable of overturning in the prior art, so that the manipulator can overturn the zinc ingot by utilizing the clamp after grabbing the zinc ingot, the structure of the clamp becomes complicated by the method, and meanwhile, the clamp is required to be provided with power, which is troublesome.
