The utility model relates to the technical field of precoated sand, and discloses a regeneration type precoated sand oscillation device which comprises a box body assembly, a heating assembly is installed at the top of the box body assembly, an oscillation assembly is placed at the bottom of the heating assembly, and a discharging assembly is arranged on one side of the oscillation assembly. The flattened material is uniformly heated through the heating pipe, the surface coating softening of the material is facilitated, the difficulty of subsequent oscillation treatment is reduced, the metal strip can repeatedly jump when falling after being adsorbed by an electromagnetic plate through the cooperation of the electromagnetic plate, the metal strip and a first spring, and the separation effect is enhanced; light impurities generated in the vibration process are separated out through negative pressure generated by the draught fan, then the impurities are collected to the designated position in a centralized mode through the collecting pipe, environmental pollution and manual cleaning cost are reduced, materials subjected to vibration can be discharged through the discharging hopper through overall cooperation of the spring type discharging assembly, leakage of the materials is avoided, and the service life of the materials is prolonged. And manual intervention is effectively reduced.
