Abstract
This utility model discloses an oven for a plate bending and flattening machine with an external heater. It includes an outer casing, inside which, from top to bottom, are arranged a fan shroud, an electric heating chamber, and a pressure plate area. The fan shroud houses a fan that rotates in conjunction with it, and the fan is linked to a motor. The electric heating chamber houses an electric heater, and a return air path is provided on the outer wall of the electric heating chamber. The air inlet of the electric heating chamber is connected to an air inlet, the air outlet of the electric heating chamber is connected to the air inlet of the fan shroud, the air outlet of the fan shroud is connected to the air inlet of the pressure plate area, the air outlet of the pressure plate area is connected to the air inlet of the return air path, and the air outlet of the return air path is connected to the air inlet of the fan shroud. The external heater oven for a plate bending and flattening machine provided by this utility model prevents volatile organic compounds from the PCB board from coming into contact with the electric heater, thus eliminating the fire hazard.
