The bottoms of the two exhaust fans 9 are fixedly connected to the cooling box 1, one of the exhaust fans 9 is fixedly connected to the collection cover 1 7, and the other exhaust fan 9 is fixedly connected to the collection cover 2 10. One side of the collection cover 2 10 is fixedly connected to the inner wall of the cooling box 1, and the cooling The inner wall of the cooling box 1 is slidably connected to the rack 18, and a gear 19 is meshed on the top of the rack 18. A connecting rod 20 is inserted through the gear 19, and one end of the connecting rod 20 is fixedly connected to the collecting cover 7, and the connecting rod 20 is rotatably connected to the cooling box 1. A guide member 17 is fixedly connected to one side of the rack 18, and one side of the guide member 17 is slidably connected to the cooling box 1. A hydraulic push rod 16 is fixedly connected to one side of the rack 18, and a reinforcement block is fixedly connected to one end of the hydraulic push rod 16, and one side of the reinforcement block is fixedly connected to the inner wall of the cooling box 1.

[0025] The cooling fan 5 can be used to pre-cool the mesh belt and the workpiece. Since one side of the collecting hood 10 is fixedly connected to the inner wall of the cooling box 1, the position of the collecting hood 10 is fixed. The hydraulic push rod 16 can be used to drive the rack 18 to move back and forth along the inner wall of the cooling box 1. During the movement of the rack 18, the gear 19 can be driven to rotate. Since the gear 19 is connected to the collecting hood 17 by the connecting rod 20, when the gear 19 rotates, the collecting hood 17 rotates on one side of the inner wall of the cooling box 1, so that the use angle of the collecting hood 17 can be adjusted, and then the collecting hood 17 can be used to dynamically adsorb the gas. The collecting hood 17 and the collecting hood 2 10 are both connected to the exhaust fan 9.

[0028] The spray plate 11 can be used to support the top of the spray pipe 15, so that the spray pipe 15 can be stably installed at the top of the inner cavity of the cooling box 1. A nozzle is installed at the bottom of the spray pipe 15. The connecting pipe 8 is connected to the spray pipe 15. Water can be transported to the inside of the spray pipe 15 through the connecting pipe 8 and then sprayed out through the nozzle.

At this time, the water generates a large amount of steam under the action of high temperature. The two exhaust fans 9 use the collection cover 1 7 and the collection cover 2 10 to quickly absorb and discharge the steam, reduce the accumulation of steam inside the cooling box 1, and thus reduce the gas on the cooling box. 1, reducing the use damage of the cooling box 1, the mesh belt continues to move, and the excess water enters the recovery box 6 for collection. Sponges are arranged on the surfaces of the adsorption roller 12 and the adsorption roller 2 14. When the mesh belt moves above the adsorption roller 12, the adsorption roller 12 preliminarily wipes the water stains remaining on the surface of the mesh belt, and the adsorption roller 2 14 wipes the water stains again. Then the mesh belt moves to the bottom of the cooling fan 5 again and is air-dried by the cooling fan 5. The inner wall of the auxiliary frame 13 overlaps with the adsorption roller 12, and the excess water inside the adsorption roller 12 can be discharged when the adsorption roller 12 rotates.
