Air cooling device for injection molding permanent magnetic ferrite brace pelleting

The utility model discloses an air cooling device for injection molding permanent magnetic ferrite brace pelleting. The air cooling device is characterized by comprising an air blower, an air collection pipe and an air supply pipe, wherein the air blower is arranged on one side of a pelletizer conveyor belt, the air collection pipe is arranged directly above the conveyor belt, and the air supply pipe is used for connecting the air blower with the air collection pipe; a plurality of air outlet pipes communicated with the air collection pipe are arranged below the air collection pipe in the direction of the conveyor belt; an air outlet piece is arranged below each air outlet pipe in a communicating mode. The air collection pipe is utilized for replacing a fan originally mounted at the upper part of the conveyor belt, so that the safety is improved; moreover, the air cooling device is more compact in structure, the air collection pipe extends to cover the directly upper part of the conveyor belt, and cooling can be carried out on an injection molding permanent magnetic ferrite brace according to the air outlet pipes, so that the cooling effect is greatly improved.
