Glass heated by the high temperature of the toughened glass furnace needs to be cooled after being discharged from the furnace, the cooling speed of the glass with larger thickness is lower, and the glass is cracked due to the excessively high cooling speed, so that quality accidents are caused. Therefore, the air pressure of the cooling air needs to be adjusted according to the thickness of the glass, and the quality accident is avoided. Be equipped with through section collection wind chamber B111 and cooling zone collection wind chamber B112, series connection fan subassembly B3 is through passing through section air inlet pipe B12 to passing through section collection wind chamber B111 input first cooling air, and single fan subassembly B2 passes through cooling zone air inlet pipe B13 and inputs second cooling air to cooling zone collection wind chamber B112, because single fan subassembly B2 only has a fan, and series connection fan subassembly B3 has a plurality of independent fan to establish ties, consequently, the wind pressure of first cooling air is higher than the wind pressure of second cooling air.

Because fan-shaped regulating part B411 is fan-shaped structure, when rotating and doing concertina movement, fan-shaped regulating part B411's circular arc one side all the time with the cylindrical pipe body structure the shape fit of floodgate mount pad B42's inner wall and can not touch floodgate mount pad B42's inner wall has guaranteed the fluency when rotating regulation apron B41 is rotatory. The first arc-shaped connecting part B414 plays a role of reinforcing the rotary adjusting cover plate B41, so that the arc sides of all the fan-shaped shielding parts B4211 are connected, the firmness is improved, and the shielding parts are not easy to damage when being subjected to strong wind.

Specifically, the wind shielding assembly B421 is provided with a plurality of second openings B4215, the second openings B4215 divide the wind shielding assembly B421 into a second connecting section B4212, a plurality of fan-shaped shielding portions 4211 and a plurality of second arc-shaped connecting portions B4214, the arc sides of the fan-shaped shielding portions B4211 are fixedly connected with the inner wall of the gate mounting seat B42, the vertex sides of all the fan-shaped shielding portions B4211 are connected through the second connecting section B4212, the arc sides of two adjacent fan-shaped shielding portions B4211 are connected through the second arc-shaped connecting portion B4214, and the second arc-shaped connecting portion B4214 is fixedly connected with the inner wall of the gate mounting seat B42; the second engaging section B4212 is disposed on a central axis of the gate mounting seat B42, the second engaging section B4212 is disposed with a second through hole B4213, and the lead screw 4322 passes through the second through hole B4213 and rotates in the second through hole B4213. As shown in fig. 14, since the fan-shaped shielding portion B4211 has a fan-shaped structure, the arc side of the fan-shaped shielding portion B4211 can be engaged with the inner wall of the shutter mounting seat B42, and the wind shielding effect of the second arc-shaped engagement portion B4214 is combined, so that the wind leakage from the damper outlet B321 can be prevented after the rotary shutter device B4 is closed. In addition, since the vertex sides of all the fan-shaped shielding portions B4211 are connected by the second coupling section B4212, the wind shielding member B421 can be stably fixed to the inner wall of the gate mount B42, and is not easily detached from the gate mount B42 even by strong wind.
