A reeling rod 202 is movably installed inside the discharge mounting frame 201, and a flame retardant cloth 203 is wrapped around the outer periphery of the reeling rod 202. An arrangement groove 204 is provided inside the fire door mounting frame 1.

A smoke sensor 5 is installed on one side of the fire door mounting frame 1, and a temperature sensor 6 is provided on one side of the smoke sensor 5. A controller 7 is installed inside the fire door mounting frame 1, and the smoke sensor 5, the temperature sensor 6 and the fireproof motor 208 are all electrically connected to the controller 7.

[0026] Through the above technical solution, when the smoke sensor 5 and the temperature sensor 6 detect a fire, the fire-proof motor 208 is started through the controller 7, so that the fire-proof motor 208 can drive the transmission worm 206 to rotate in the worm mounting plate 207. When the transmission worm 206 rotates, it can drive the transmission worm wheel 205 to rotate. When the transmission worm wheel 205 rotates, it can drive the unwinding rod 202 to rotate in the discharge mounting frame 201. When the unwinding rod 202 rotates, it can drive the flame-retardant cloth 203 to be released along the arrangement groove 204, thereby achieving the purpose of the flame-retardant cloth 203 blocking the flame.

[0027] like Figure 1-4 As shown, the liquid insulation component 3 includes a flame retardant liquid tank 301, which is installed inside the fire door installation frame 1.

When the transmission worm wheel 205 rotates, it can drive the unwinding rod 202 to rotate in the discharge mounting frame 201. When the unwinding rod 202 rotates, it can drive the flame-retardant cloth 203 to be released along the arrangement groove 204, so as to achieve the purpose of the flame-retardant cloth 203 blocking the flame;

[0034] When the automatic flame retardant heat insulation component 2 is started, the controller 7 starts the liquid outlet valve 303, so that after the liquid outlet valve 303 is started, the flame retardant liquid in the flame retardant liquid tank 301 is discharged through the liquid outlet pipe 302, so that the flame retardant liquid is sprayed into the flame retardant cloth 203, thereby improving the flame retardant effect;

[0035] When the automatic flame retardant and heat insulation component 2 is started, the controller 7 starts the exhaust valve 403, so that the carbon dioxide in the carbon dioxide tank 401 is ejected through the exhaust pipe 402 and the exhaust nozzle 404, so that a large amount of carbon dioxide is accumulated between the flame retardant cloth 203 and the fire door, thereby achieving the purpose of flame retardancy through carbon dioxide after the flame retardant cloth 203 fails.
