The invention belongs to the technical field of float glass production, and provides a reversing connecting mechanism for a flue damper of a glass melting furnace. The glass melting furnace flue flashboard reversing connecting mechanism is provided with a transmission platform arranged between a flashboard A and a flashboard B; a positive and negative rotation transmission motor is fixed on the transmission platform; the output end of the positive and negative rotation transmission mechanism is connected with a transmission gear; driven gears are arranged on the two sides of the transmission gear correspondingly; the two driven gears are arranged corresponding to the A-side flashboard and the B-side flashboard respectively, and the A-side flashboard and the B-side flashboard are connectedwith the corresponding driven gears into a whole through steel wire ropes respectively; therefore, a linkage structure is formed between the A-side flashboard and the B-side flashboard, so that synchronous reversing of the glass melting furnace flue flashboard is achieved under the action of the forward and reverse rotation transmission motor, that is, when combustion-supporting air enters from the A-side flashboard, the A-side flashboard is cut off, and when the combustion-supporting air enters from the B-side flashboard, the B-side flashboard is cut off. By means of the mechanism, synchronous linkage between the gate plates on the two sides is achieved, and the mechanism has the advantages of being simple in structure and convenient to operate.
