Automatic powder adding device for production of rare earth magnetic materials

Abstract

An automatic powder adding device for production of rare earth magnetic materials comprises a cylinder, wherein a storage hopper is arranged on the upper portion of one side in the cylinder, a plurality of accommodation cavities are formed in the storage hopper, and a notch is formed in the lower portion of each accommodation cavity; a rotation wheel is arranged on the lower portion of the storage hopper, a weighing groove is formed in the rotation wheel, a measuring cup is arranged on the upper portion of the weighing groove, and the opening diameter of the measuring cup is identical to the opening diameters of the notches; meanwhile, baffles are arranged symmetrically on the inner side of the portion, above the measuring cup, of the rotation wheel, and a travel switch is arranged below the baffles; a rotation shaft is sleeved with the rotation wheel, a timer is arranged on the rotation shaft, and the travel switch is connected with the timer; the travel switch and the timer are used in cooperation, so that the measuring cup is controlled to be rotated to the notches of the different accommodation cavities, and different kinds of rare earth magnetic powder can be added automatically; a conveying belt is arranged on the lower portion of the rotation wheel and is connected with a feeding port of a mixing chamber through a buffering belt; an elastic vibration layer is arranged on the lower portion of the conveying belt so that the rare earth magnetic powder can be prevented from being stacked on the conveying belt.

Description

technical field [0001] The invention relates to the technical field of rare earth magnetic material powder addition, in particular to an automatic powder addition device for rare earth magnetic material production. Background technique [0002] During the processing of rare earth magnetic materials, it is necessary to pre-mix the powdered rare earth magnetic powder in the mixing equipment, and then proceed to the next step of production. However, rare earth magnetic powder is prone to oxidation, and the high temperature in the production process will accelerate the oxidation of rare earth magnetic powder. Oxidation is not conducive to the control of the magnetic properties of sintered rare earth magnetic materials; at the same time, adding too much powdered rare earth magnetic powder to the mixing container at one time is not conducive to The mixing of various rare earth magnetic powders can easily lead to an imbalance in the amount of rare earth magnetic powder added in the...

Problems solved by technology

However, rare earth magnetic powder is prone to oxidation, and the high temperature in the production process will accelerate the oxidation of rare earth magnetic powder. Oxidation is not conducive to the control of the magnetic properties of sintered rare earth magnetic materials; at the same time, adding too much powdered rare earth magnetic powder to the mixing container at one time is not conducive to The mixing of various rare earth magnetic powders can easily lead to an imbalance in the amount of rare earth magnetic powder added in the produced rare earth magnetic materials, which in turn affects the quality of rare earth magnetic materials

At present, the mixing of rare earth magnetic powder is mainly artificially added, which not only has low work efficiency, but also has high labor intensity.
