[0025] In specific use, when the mesh belt normalizing furnace is used, the heat dissipation box 2 can be used to protect both sides of the furnace and provide heat dissipation and heat insulation effects. The pumping piston 8 can be driven to slide inside the output box 5 and the input box 6 by the action of the first reciprocating rod 81 and the second reciprocating rod 82 at the same time, so that the cooling oil inside the oil storage tank 4 can be transported to the output box 5 through the one-way valve 7, and then transported from the one-way valve 7 to the cooling box 3 for cooling. At the same time, the pumping piston 8 slides inside the input box 6, and the cooling oil inside the cooling box 3 can be pumped to the input box 6 through the one-way valve 7, and then through the one-way valve 7.

When the cooling oil in the cooling box 3 is completely evacuated, the vacuum effect can be used to achieve heat insulation, thereby improving the heat insulation effect of the heat dissipation box 2 on the middle position on both sides of the mesh belt normalizing furnace.

[0026] Preferably, a top frame 9 is fixedly mounted on the top of the heat dissipation box 2, and two driving rods 91 are rotatably connected to the inner side wall of the top frame 9.

[0033] During specific use, the second rotating rod 134 can adjust the position of the first rotating rod 132 and the second rotating rod 134 by adjusting the distance between the first rotating rod 132 and the second rotating rod 134 through the electric telescopic rod 133, so that the driving motor 131 can drive the first rotating rod 132 and the second rotating rod 134 to drive on the motor frame 13.

[0034] Preferably, a driving gear 135 is fixedly mounted on the outer side of the second rotating rod 134 , a driven gear 92 is fixedly mounted on the outer side of the driving rod 91 , and the outer side of the driving gear 135 meshes with the outer side of the driven gear 92 .

[0035] During specific use, when the second rotating rod 134 moves in position, it can engage with the driven gear 92 on the single driving rod 91 through the driving gear 135, and can drive the single driving rod 91 to rotate.
