[0031] The staff can observe the drying process of the material inside the oven 1 through the transparent plate 6 in the observation port. The two ends of the oven 1 are respectively provided with a feed port 2 and a discharge port 31, which are convenient for the material to enter or leave the oven 1; when the side port is to be opened, the rotating shaft 27 is rotated, and the rotating shaft 27 will rotate with the rotating block 28, and the rotating block 28 will rotate the door panel 5 upward, so that the side port can be opened. The rotating shaft 27 is rotated in the opposite direction, and the door panel 5 will rotate downward, so as to close the side port. The material of the transparent plate 6 can be sealed tempered glass.

[0032] like Figure 1-Figure 4 As shown, the heat circulation mechanism includes an air inlet duct 34, an air return duct 9, a first filter box 13, a first filter screen 12, an air inlet fan 11 and a heating box 8, the air inlet duct 34 is fixedly connected to the oven 1, the first filter box 13 and the return air duct 9, the first filter screen 12 is fixed on the first filter box 13, the air inlet fan 11 is fixed on the return air duct 9, the return air duct 9 is fixedly connected to the heating box 8, the heating box 8 is fixed on the oven 1, and an electric heating rod 30 is fixedly arranged inside.

[0033] When a heat cycle is to be performed, the air inlet fan 11 is started first. The air inlet fan 11 will extract the outside air and the air in the oven 1 through the air inlet pipe 34 and discharge them into the return air pipe 9. Then the air in the return air pipe 9 will enter the heating box 8 and be heated by the electric heating rod 30. Finally, hot air will be blown into the oven 1 to dry the logistics in the oven 1. The outside air will first pass through the first filter screen 12 to enter the first filter box 13, and then enter the air inlet pipe 34. The first filter screen 12 can filter the outside air.

[0034] like Figure 2 and Figure 5 As shown, it also includes a return air mechanism, which includes a second filter box 16, a return air housing 17 and a return air frame 24. The second filter box 16 is fixed in the oven 1 and connected to the heating box 8. A second filter screen 21 is fixedly arranged in the second filter box 16. The return air housing 17 is fixedly connected to the second filter box 16 and the return air frame 24, and an upwind distribution plate 22 and a downwind distribution plate 23 are fixedly arranged inside. An air guide block 18 is fixedly arranged in the return air frame 24.

[0035] Ventilation holes are provided on the upwind distribution plate 22 and the downwind distribution plate 23. The hot air in the heating box 8 will first enter the second filter box 16 and be filtered by the second filter screen 21, then enter the return air housing 17, and then enter the return air frame 24 through the ventilation holes on the upwind distribution plate 22 and the downwind distribution plate 23, and be blown to the logistics in the oven 1 from between the two air guide blocks 18.

[0036] like Figure 1 and Figure 2As shown, a wind speed transmitter 10 is fixedly provided on the oven 1 , and the wind speed transmitter 10 is electrically connected to a wind speed control module, and the wind speed control module is electrically connected to the air inlet fan 11 .

[0037] The wind speed transmitter 10 is located below the return air frame 24 and can detect the wind speed of the return hot air. After the wind speed transmitter 10 detects the wind speed of the return hot air, it will transmit a signal to the wind speed control module. The wind speed control module determines whether the wind speed of the return air is within the set range. If the return air speed is too fast, the wind speed control module controls the air inlet fan 11 to reduce the air inlet speed, thereby reducing the wind speed of the wind in the return air duct 9 entering the heating box 8, and then reducing the wind speed of the return air so that the wind speed of the return air reaches the set range. If the return air speed is too slow, the wind speed control module controls the air inlet fan 11 to increase the air inlet speed, thereby increasing the wind speed of the wind in the return air duct 9 entering the heating box 8, and then increasing the wind speed of the return air so that the wind speed of the return air reaches the set range. The wind speed control module can be a single-chip microcomputer.

[0038] A temperature sensor is fixedly disposed in the heating box 8 , and the temperature sensor is electrically connected to a temperature control module, and the temperature control module is electrically connected to the electric heating rod 30 .

[0039] The temperature sensor can detect the temperature of the hot air in the heating box 8 and transmit the detected signal to the temperature control module. The temperature control module will determine whether the temperature of the hot air reaches the set range. If the hot air temperature is lower than the set temperature range, the temperature control module will control the electric heating rod 30 to increase the heating value so that the temperature of the hot air can reach the set temperature range. The temperature control module can be a single-chip microcomputer.

[0043] When part of the air in the oven 1 is to be exhausted, the air outlet fan 15 is started first, and the air in the oven 1 enters the air outlet box 20 through the opening on the bottom surface of the air outlet box 20, then enters the air outlet pipe 14 from the air outlet box 20, and is finally exhausted from the air outlet pipe 14. The air in the oven 1 enters the air inlet box 19 through the opening on the bottom surface of the air inlet box 19, and then enters the air inlet pipe 34 from the air inlet box 19.
