[0026] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes. Example

[0028] Two square blocks 14 are fixedly installed on both sides of the transverse cylinder block 1, and two round sleeve blocks 15 are rotatably installed between the four square blocks 14. Stop blocks 16 are fixedly installed on the two round sleeve blocks 15, and rubber curtains 17 are fixedly installed on the bottoms of the two stop blocks 16.

[0031] In this embodiment:

[0032] When the PCB board needs to be cooled, the two cooling fans 11 and the fan 13 are started first. The two cooling fans 11 convert electrical energy into wind energy and inject cold air into the transverse cylinder block 1. The fan 13 generates wind energy to blow the transverse cylinder block 1, thereby reducing the internal temperature of the transverse cylinder block 1 and making the circulation of cold air in the transverse cylinder block 1 more active. Then the first motor 10 is started, and the output shaft of the first motor 10 drives the corresponding rotating rod 6, and the rotating rod 6 drives the corresponding conveying wheel 7. With the cooperation of the conveying wheel 7 and a conveyor belt 8, the conveyor belt 8 is in a transmission state, and the PCB board is placed on the conveyor belt 8. Driven by the conveyor belt 8, the PCB board will gradually enter the transverse cylinder block 1. With the cooperation of the fixed block 9, the rubber curtain 17 will be lifted when the fixed block 9 passes through the rubber curtain 17 to prevent the cold air in the transverse cylinder block 1 from flowing out. When the PCB board is conveyed and moved in the transverse cylinder block 1, the temperature of the PCB board will gradually decrease due to the influence of the temperature in the transverse cylinder block 1.
