Technical Field

[0001] The utility model relates to the technical field of coated sand feeding, in particular to an automatic coating sand feeding device. Background Art

[0002] Coated sand is a molding sand or core sand whose surface is covered with a layer of solid resin film before molding. The preparation methods include two coating processes: cold method and hot method. Among them, the cold method uses ethanol to dissolve the resin, and adds urotropine during the sand mixing process, so that the two are coated on the surface of the sand particles, and the ethanol evaporates to obtain coated sand; while the hot method preheats the sand to a certain temperature, adds resin to melt it, stirs to coat the resin on the surface of the sand particles, adds urotropine aqueous solution and lubricant, cools, crushes, and sieves to obtain coated sand. Coated sand is used for steel castings and iron castings. The adaptability of automatic feeding equipment to materials is limited, and it needs to be selected and adjusted according to actual conditions, so it is easy to cause blockage and leakage.

[0010] Beneficial Effects

[0011] The utility model provides an automatic feeding device for coated sand, which has the following beneficial effects:

[0012] (1) This kind of automatic feeding equipment for coated sand pours the coated sand into the control plate in the inner cavity of the automatic feeding hopper. In order to avoid blockage during discharge, the control plates are driven to slowly move away from each other by starting the electric push rod, and the coated sand flows through the inner cavity of the conveying tube through the gap between the two control plates. At the same time, the second driving motor is also started. The second driving motor drives the stirring rod on the stirring shaft to flip the coated sand at the outlet of the automatic feeding hopper. The crushing blocks on the stirring rod break up the agglomerated coated sand, making it easier for the coated sand to enter the inner cavity of the conveying tube, reducing blockage and leakage.
