[0019] See attached document Figure 1-7 A heat treatment device for wooden pallets includes a heat treatment chamber 1. A movable plate 2 is horizontally movable inside the heat treatment chamber 1. Guide rods 3 are fixedly installed at the four corners of the top of the movable plate 2. Side plates 4 are fixedly installed at equal intervals on the outer surface of the guide rods 3. Load-bearing plates 5 are fixedly connected between the side walls of the side plates 4. Wood can be placed on the top surface of the load-bearing plates 5, and a limiting component is provided on the top surface of the wood. A hot air box 6 is fixedly installed on the rear side of the heat treatment chamber 1, and a heat adjustment mechanism is provided inside the hot air box 6. Heating modules are installed at multiple locations on the inner wall of the heat treatment chamber 1. A door panel can be installed at the front opening of the heat treatment chamber 1. The multiple heating modules installed on the inner wall of the heat treatment chamber 1 can raise the temperature inside the heat treatment chamber 1, thereby drying the moisture in the wood.

[0020] In this embodiment, horizontal grooves 100 are symmetrically provided on the upper surface of the inner bottom wall of the heat treatment chamber 1. A first motor 7 is fixedly installed at the bottom end of one side of the rear wall of the heat treatment chamber 1. A lead screw 8 is connected to the output end of the first motor 7. The lead screw 8 rotates inside the horizontal groove 100. A threaded block 9 is installed on the external thread of the lead screw 8. The bottom end of the threaded block 9 slides inside the horizontal groove 100. A horizontal rod 10 is fixedly installed inside another horizontal groove 100. A horizontal block 11 is slidably installed on the outer surface of the horizontal rod 10. The threaded block 9 and the horizontal block 11 are fixedly installed at both ends of the front side of the bottom wall of the movable plate 2.

[0021] It should be noted that the first motor 7 drives the lead screw 8 to rotate, and the threaded block 9 moves along the inside of the horizontal groove 100 into the heat treatment chamber 1. The horizontal block 11 moves along the inside of the horizontal groove 100 on the horizontal rod 10, which can drive the moving plate 2 to move into the heat treatment chamber 1, so that the fixed wood can be moved into the heat treatment chamber 1. By using the reverse movement of the moving plate 2 inside the heat treatment chamber 1, the wood can be moved out of the heat treatment chamber 1, which facilitates the quick loading and unloading of the wood.

[0022] In this embodiment, the limiting component includes positioning grooves 400 formed at both ends of the side plate 4. An directional block 13 is fixedly connected inside the positioning groove 400 by a connecting spring 12. The directional block 13 slides inside the positioning groove 400. A limiting plate 14 is fixedly connected to the top of the directional block 13. The limiting plate 14 is tightly attached to the upper surface of the wood.

[0023] It should be noted that the upward lifting of the limiting plate 14 causes the directional block 13 to move upward along the inner side of the positioning groove 400 and elastically stretch the connecting spring 12, so that the wood can be placed on the top of the load-bearing plate 5. The two ends of the wood are located on the inner side of the side plate 4 and abut against the inner side wall of the side plate 4. Then, when the connecting spring 12 rebounds, it causes the directional block 13 to move downward along the inside of the positioning groove 400, so that the limiting plate 14 fits tightly against the upper surface of the wood, thereby achieving the positioning of the wood.

[0024] In this embodiment, a second motor 15 is fixedly installed at the top of the hot air box 6. A screw 16 is connected to the output end of the second motor 15. A moving block 17 is installed on the external thread of the screw 16. Vertical rods 18 are fixedly installed on both sides inside the hot air box 6. A slider is slidably installed on the outer surface of the vertical rod 18. A mounting frame 19 is fixedly connected between the slider and the end of the moving block 17. A connecting rod 20 is fixedly installed at one end of the moving block 17 and the slider. A third motor 21 is fixedly installed inside the connecting rod 20. A fan 22 is installed at the output end of the third motor 21. A mounting frame 23 is fixedly installed at one end of the connecting rod 20. Heating wires 24 are installed at both ends of the inner side of the mounting frame 23. A cooler 25 is provided between the two heating wires 24.

[0025] It should be noted that the operation of the second motor 15 can drive the screw 16 to rotate, and the moving block 17 moves up and down along the screw 16. Through the connection of the connecting rod 20, the slider moves up and down along the vertical rod 18. When the third motor 21 drives the fan 22 to run, the hot air blown through the heating wire 24 can blow into the interior of the heat treatment chamber 1, which can spread the heat inside the heat treatment chamber 1 more evenly and make the wood heat evenly.

[0026] In this embodiment, rubber strips 26 are provided on both sides of the hot air box 6, and the rubber strips 26 are tightly attached to the connection between the hot air box 6 and the heat treatment box 1.

[0027] It should be noted that the connection between the hot air box 6 and the heat treatment box 1 should be kept sealed.

[0028] The working principle of this utility model is as follows: In use, the upward lifting of the limiting plate 14 first causes the directional block 13 to move upward along the inner side of the positioning groove 400, elastically stretching the connecting spring 12. This allows the wood to be placed on top of the load-bearing plate 5, with both ends of the wood located inside the side plate 4, abutting against the inner wall of the side plate 4. Then, as the connecting spring 12 rebounds, it causes the directional block 13 to move downward along the inside of the positioning groove 400, making the limiting plate 14 tightly adhere to the upper surface of the wood. Next, the operation of the first motor 7 drives the lead screw 8 to rotate, causing the threaded block 9 to move along the inside of the horizontal groove 100 into the heat treatment chamber 1. The horizontal block 11 moves along the inside of the horizontal groove 100 on the horizontal rod 10, which can move the moving plate 2 into the heat treatment chamber 1, allowing the fixed wood to move into the heat treatment chamber 1. Multiple heating modules installed on various parts of the inner wall of the heat treatment chamber 1 then... The heat treatment chamber 1 can be heated to dry the moisture in the wood. Simultaneously, the second motor 15 drives the screw 16 to rotate, and the moving block 17 moves up and down along the screw 16. Connected by the connecting rod 20, the slider moves up and down along the vertical rod 18. With the third motor 21 driving the fan 22, the heating wire 24 blows hot air into the heat treatment chamber 1, distributing the heat more evenly and ensuring uniform heating of the wood. After heat treatment, the heating wire 24 is stopped, and the cooler 25 is activated to blow cold air into the heat treatment chamber 1, accelerating the cooling process. The moving plate 2 moves in the opposite direction inside the heat treatment chamber 1, allowing the wood to be moved out for easy and quick handling.

[0029] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
