Driven by the reduction motor 12, the mesh belt chain 11 carries the material on the conveyor line 1 and cools it through the air cooling device 2, wherein the air cooling device 2 blows air to the material from the bottom through the blower 21, and the exhaust fan 22 absorbs the heat from the top, thereby improving the cooling efficiency of the air cooling device 2. The air sweeping plate 3 installed at the outlet of the blower 21 can evenly sweep the exported gas to the material, and at the same time can adjust the height of the adjustable support frame 4 according to the size of the material, thereby ensuring the cooling efficiency of the material. And the whole process is controlled by the PLC controller 5, which effectively reduces labor costs and improves the cooling efficiency of materials.

[0027] Reference Figure 1 and Figure 2 , there are several air cooling boxes 15 continuously distributed on the conveyor line 1, wherein a single air cooling box 15 corresponds to a group of blowers 21 and exhaust fans 22, and a temperature sensor 16 is installed on the side of the air cooling box 15. The conveyor line 1 is decomposed into multiple air cooling boxes 15, and a single air cooling box 15 is equipped with a blower 21 and a hair dryer to cool the material, and the temperature of the material is monitored in real time during the cooling process.

[0028] Reference Figure 1 and Figure 2 A protective frame 17 is installed at the bottom of the conveyor line 1, and the protective frame 17 includes a plurality of frame bodies 171, which are hinged with each other, and a driven roller 14 is arranged in the mesh belt chain 11 at the hinge. A lifting rod 172 is installed at the bottom of the frame body 171, and a fan limit frame 173 is also arranged at the bottom of the frame body 171, and air inlets 174 are arranged on both sides of the fan limit frame 173. The protective frame 17 installed at the bottom of the conveyor line 1 is used to connect two adjacent air cooling boxes 15, and a plurality of frame bodies 171 in the protective frame 17 are connected by hinges. Under the action of the lifting rod 172 at the bottom of a single frame body 171, the height of the frame body 171 in the conveyor line 1 can be freely adjusted to meet the loading and unloading requirements of different heights, and a driven roller 14 is arranged at the hinge between the frame bodies 171 and the frame bodies 171, so as to ensure the continuity of the conveyor line 1 as a whole.

[0029] Reference Figure 1 and Figure 2 The adjustable support frame 4 is located at the top of the frame 171, adopts an inverted U-shaped mechanism, and the two sides of the adjustable support frame 4 are adapted to the slide groove 175 inside the protection frame 17 through the sliding protrusions 42.

After the previous process is completed, the material is transported to the mesh belt chain of this conveyor line 1. The mesh belt chain uses a relatively large mesh. When the mesh belt chain moves the material, the blower 21 at the bottom can blow air to cool the bottom of the material. After passing through each fan, the temperature sensor 16 senses that the material has reached the set temperature, and the subsequent air cooling box 15 will no longer work to ensure the temperature balance of the material reaching the next process.
