Specifically, when the loading trolley 4 travels on the track 3 to the receiving position, the first motor 8 drives the first conveyor chain 9 to receive the material 6 delivered from the outside. After the material 6 is completely transported onto the first conveyor chain 9, the first motor 8 stops operating. Then, the loading trolley 4 travels on the track 3 until it is aligned with the receiving conveyor mechanism 2, and then the first motor 8 drives the first conveyor chain 9 again to transport the material 6 onto the receiving conveyor mechanism 2. More specifically, the loading conveyor mechanism 5 also includes a first support plate installed on the inner side of the first conveyor chain 9 and used to support the first conveyor chain 9 upwards.

[0085] The drive mechanism is connected to the curing chamber 1 and is also connected to the chamber door 19 and is used to drive the chamber door 19 to move up and down in the guide rail component to open and close the material inlet; specifically, during the feeding or unloading process, the drive mechanism drives the chamber door 19 to rise to open the material inlet, and during the heat preservation and curing process, the drive mechanism drives the chamber door 19 to fall to close the material inlet.

[0086] like Figure 4 , 10 As shown, the guide rail component may include a left guide rail 20 and a right guide rail 21, both of which are connected to the curing chamber 1;

[0096] The fan 27 is installed at the air inlet 31 and is used to draw air so that the air in the return air duct 30 flows from the air inlet 31 into the air heat exchanger 26 and flows out from the air outlet 32 ​​into the air inlet duct 29;

[0097] The air heat exchanger 26 also has a heat transfer medium inlet for receiving heat transfer oil and a heat transfer medium outlet for discharging heat transfer oil. Specifically, the material conveying mechanism 2 conveys material 6 into the main chamber 28. Under the suction of the fan 27, air in the return air duct 30 flows into the air heat exchanger 26 from the air inlet 31 and flows out to the air inlet duct 29 from the air outlet 32. The air in the air inlet duct 29 flows into the main chamber 28 to heat and solidify the material 6 in the main chamber 28. Then, the air in the main chamber 28 flows back into the return air duct 30, thus realizing the internal circulation of air. Furthermore, the heat transfer oil flowing into the air heat exchanger 26 exchanges heat with the air flowing into the air heat exchanger 26, thereby heating the air and maintaining it at a certain temperature.

In this embodiment, a temperature sensor is also installed in the return air duct 30. When either the temperature sensor in the main chamber 28 or the temperature sensor in the return air duct 30 detects a temperature exceeding 105°C, the controller controls the oil temperature controller 42 to stop pumping heated heat transfer oil into the air heat exchanger 26. Specifically, the oil temperature controller 42 has an electric heater for heating the introduced oil and an oil pump for pumping the heat transfer oil. The specific structure of the oil temperature controller 42 is prior art well known to those skilled in the art and will not be described in detail in this embodiment. In this embodiment, the wall of the curing chamber 1 includes an inner wall layer, an outer wall layer, and a thermal insulation material layer disposed between the inner wall layer and the outer wall layer. The thermal insulation material layer is made of aluminum silicate, the inner wall layer is made of stainless steel, and the outer wall layer is made of carbon steel.

[0107] In summary, firstly, the loading trolley 4 travels on the track 3 to the receiving position. At this time, the loading conveyor 5 receives the material 6 delivered from the outside. After the material 6 is completely transported onto the loading conveyor 5, the loading conveyor 5 stops operating.
