[0023] As Figure 3 shown in the figure, the inner wall of the box 1 is fixedly installed with a plurality of support rods 9, the plurality of support rods 9 are symmetrically distributed about the center line of the box 1, the side of the support rod 9 away from the inner wall of the box 1 is provided with a sliding groove 10, the inside of the sliding groove 10 is provided with a plurality of sliding blocks 11, the plurality of sliding blocks 11 are linearly distributed along the edge line direction of the support rod 9, the side of the corresponding support rod 9 of the sliding block 11 is provided with a through groove 12, and the through groove 12 penetrates the sliding block 11, the inside of the through groove 12 is provided with a fixing rod 13, the staff selects the number of sliding blocks 11 according to the size and quantity of the material to be processed, and controls the distance between the two sliding blocks 11 close to each other according to the shape of the material, moves the sliding block 11 to the appropriate position, and inserts the fixing rod 13 into the corresponding through groove 12, so that the sliding block 11 is fixed in the appropriate position, and the end of the fixing rod 13 is provided with a pull ring, which is convenient for the staff to adjust the sliding block 11.

[0024] As Figure 4 shown in the figure, the upper surface of the humidifying box 3 is fixedly installed with a water inlet pipe 14, the water inlet pipe 14 extends into the humidifying box 3, and the bottom of the inner wall of the humidifying box 3 is fixedly installed with a heating wire 15. The external water flow enters the humidifying box 3 through the water inlet pipe 14, and the heating wire 15 warms the liquid in the humidifying box 3. When no water flow is added, the water inlet pipe 14 is also responsible for the air inlet of the humidifying box 3.

[0025] As Figure 5 shown in the figure, the inner wall of the warming box 6 is fixedly installed with a plurality of warming plates 16, the plurality of warming plates 16 are linearly distributed along the edge line direction of the warming box 6, the inner wall of the corresponding warming box 6 of the warming plate 16 is fixedly provided with a filter plate 17, and the side of the warming box 6 away from the air pipe 8 is provided with an air inlet groove 18.

The plurality of warming plates 16 prolong the moving path of the external air in the warming box 6, so that the external air is uniformly heated.

[0026] As Figure 3 shown in the figure, the inside of the box 1 is provided with a heat preservation cavity 19, the design of the heat preservation cavity 19 can effectively reduce the heat exchange between the inside of the box 1 and the outside environment, so as to maintain the stability of the inside temperature of the box 1. Through the heat insulation effect of the heat preservation cavity 19, the energy loss in the heating process can be reduced, and the utilization rate of energy can be improved. Stable temperature and closed environment can help to speed up the drying process of the wooden pallet, improve the processing efficiency, and prevent the water vapor in the box 1 from condensing into water droplets on the inner wall of the box 1. Due to the high temperature in the box 1, the water droplets remaining in the box 1 evaporate again, so that the humidity in the box 1 increases.

[0027] As Figure 2As shown, an air outlet pipe 20 is provided on the upper surface of the box 1. The air outlet pipe 20 is connected to the box 1. The presence of the air outlet pipe 20 helps to regulate the pressure inside the box 1, prevents excessive pressure caused by gas accumulation, and allows the gas inside the box 1 to be discharged smoothly, thereby promoting the circulation of gas inside the box 1.

[0028] like Figure 4 As shown, the positions of the connecting pipe 4 and the gas supply pipe 8 correspond to each other. The design of the corresponding positions of the connecting pipe 4 and the gas supply pipe 8 ensures that the gas flow path inside the device is smoother and more efficient. Since there is water flow inside the humidification box 3, the corresponding positions of the connecting pipe 4 and the gas supply pipe 8 facilitate the full mixing of the humid and hot gas and the heated gas entering the humidification box 3 before entering the buffer box 5 through the connecting pipe 4.

[0029] Working Principle: During preparation, the operator selects the appropriate number of sliders 11 based on the size and quantity of the material to be processed. The distance between two sliders 11 that are close to each other is controlled according to the shape of the material. After moving the sliders 11 to the appropriate position, the fixing rod 13 is inserted into the corresponding through slot 12, thus fixing the sliders 11 in the correct position. During operation, when the humidity sensor in the chamber 1 detects high humidity, the first and third valves close. External air enters the heating chamber 6 through the air inlet slot 18. The heating plates 16 heat the external air, while the filter plates 17 filter the external air. Multiple heating plates 16 extend the movement of external air within the heating chamber 6. The path ensures uniform heating of the external air, and the gas inside the chamber 1 leaves the equipment through the exhaust pipe 20; thus maintaining the temperature and humidity inside the chamber 1. When the humidity inside the chamber 1 is low, the first valve, the second valve, and the third valve are all opened, and the external water flows into the humidification chamber 3 through the water inlet pipe 14. The heating wire 15 heats the liquid inside the humidification chamber 3. When no water is added, the water inlet pipe 14 is also responsible for the air intake of the humidification chamber 3. Some of the high-temperature gas in the heating chamber 6 enters the humidification chamber 3 through the air supply pipe 8. After the humid and hot gas and the heated gas are fully mixed, they enter the buffer chamber 5 through the connecting pipe 4. The gas in the buffer chamber 5 enters the chamber 1 through the air inlet pipe 2, thus maintaining the temperature and humidity balance inside the chamber 1.
