Abstract
The invention discloses an explosion-proof motor used for a bag-making machine. The explosion-proof motor includes a motor, current sources, a casing, an explosion-proof layer, a valve, a temperature sensor, a first comparator, a first signal switch, and an electromagnetic relay. The explosion-proof layer is formed on the external surface of the casing, and is equipped with an opening. The valve is arranged in the opening of the explosion-proof layer. The temperature sensor is arranged on the external surface of the casing to convert a temperature signal into an electric signal. The first comparator is connected to the temperature sensor. When the temperature exceeds a first temperature threshold, the first comparator converts the electric signal into a first effective level signal. The first signal switch is connected to the first comparator. When the first signal switch receives the first effective level signal, the first signal switch is switched off. When the first signal switch is switched off, the electromagnetic relay, the first signal switch and the current sources are connected to form a closed loop, and the electromagnetic relay is closed to drive the valve to be closed. When the first signal switch is switched on, the electromagnetic relay is open to drive the valve to be open. The explosion-proof is prevented from exploding.
