The fixed block 8 is connected to one side of the support plate 6, and has a positioning block 12 and a limit plate 9 inside to fix the wood and limit its movement. The positioning block 12 and the positioning groove 10 are used together to ensure that the limit plate 9 is accurately positioned to fix the wood. The limit plate 9, the clamping block 11 and the reset plate 15 work together. The limit plate 9 slides in the fixed block 8, and the clamping block 11 cooperates with the reset plate 15 to clamp and release the wood. The telescopic rod 13 and the spring 14 are located on the side of the positioning groove 10 away from the clamping block 11, providing elastic force to help the reset plate 15 return to its original position. The vacuum pump 17 is fixed to the top edge of the kiln body 1, and moisture is extracted from the kiln body 1 through the exhaust pipe 18.

The exhaust pipe 30 is connected to the front side of the installation box 20 and the left side of the kiln body 1, and is used to return the treated air to the inside of the kiln body 1.

[0034] Reference Figure 1 and Figure 4 The dehumidification component includes a motor 21, which is fixedly connected to the left side of the top of the motor 21, a threaded rod 22 is fixedly connected to the output end of the motor 21, and a threaded sleeve 23 is threadedly connected to the outer side of the threaded rod 22. A fixed rod 24 is fixedly connected to the left side of the inside of the installation box 20, and a slider 25 is slidably connected to the outside of the fixed rod 24.

[0035] Specifically, the second motor 21 is fixed inside the installation box 20, and is connected to the threaded rod 22 through the output end to drive the threaded rod 22 to rotate. The threaded rod 22 is fixedly connected to the output end of the second motor 21, and is externally threadedly connected to the threaded sleeve 23, which drives the threaded sleeve 23 to move by rotation. The threaded sleeve 23 is threadedly connected to the outside of the threaded rod 22, and moves with the rotation of the threaded rod 22, and drives the squeezing roller 26 to move together with the slider 25. The fixed rod 24 is fixed to the left side inside the installation box 20, and is externally slidably connected to the slider 25 to provide guidance and support for the slider 25. The slider 25 is slidably connected to the outside of the fixed rod 24, and moves together with the threaded sleeve 25, driving the squeezing roller 26 to move along the direction of the fixed rod 24. The squeezing roller 26 is rotatably connected between the slider 25 and the threaded sleeve 23. As the slider 25 and the threaded sleeve 23 move, the squeezing roller 26 will roll on the silica gel water absorbent 27 to help squeeze out the moisture absorbed by the silica gel water absorbent layer 27. The silica gel water absorbent layer 27 is fixed to the rear side of the inside of the installation box 20 to absorb the moisture passing through. When the squeezing roller 26 rolls on it, the silica gel water absorbing layer 27 will be squeezed to release the absorbed moisture. The hollow plate 28 is fixedly connected to the back side of the silica gel water absorbing layer 27 to allow air circulation while supporting the silica gel water absorbing layer 27. The collecting box 29 is slidably connected to the inside of the installation box 20 to collect the moisture squeezed out of the silica gel water absorbing layer 27.

[0036] Reference Figure 3 - Figure 5 A handle 31 is fixedly connected to the front edge of the sealing door 2, the outside of the reset block 16 is slidably connected to the inside of the fixed block 8, the two sides of the outside of the reset plate 15 are slidably connected between the two positioning blocks 12, one end of the spring 14 is fixedly connected to the side of the limit plate 9 away from the clamping block 11, and the other end of the spring 14 is fixedly connected to the inner wall of the fixed block 8, the outer side of the clamping block 11 is slidably connected to the inside of the fixed block 8, both ends of the threaded rod 22 are rotatably connected to the inside of the installation box 20, and the extrusion roller 26 is abutted against the silica gel water absorption layer 27.

[0037] Specifically, the handle 31 is fixedly connected to the front edge of the sealing door 1, which is convenient for the operator to open and close the sealing door and ensure the sealing performance of the kiln body 1. The reset block 16 is slidably connected to the inside of the fixed block 8 and works together with the reset plate 15. When the limit plate 9 moves, the reset block 15 slides in the fixed block 8 to help the reset plate 15 return to its original position and maintain the stability of the clamping force. The reset plate 15 is slidably connected between the two positioning blocks 12 and cooperates with the clamping block 11. When the wood is clamped or released, the reset plate 15 slides between the positioning blocks 12 on both sides of the outside to ensure the accuracy and stability of the wood position. One end of the spring 14 is fixedly connected to the side of the limit plate 9 away from the clamping block 11, and the other end is fixedly connected to the side of the limit plate 9 away from the clamping block 11. The ends are fixedly connected to the inner wall of the fixed block 8, providing elastic force to help the limit plate 9 and the clamping block 11 return to the initial position and keep the wood firmly clamped. The clamping block 11 is slidably connected to the inside of the fixed block 8, and works together with the reset plate 15 and the limit plate 9 to clamp or release the wood by sliding, thereby ensuring the fixation of the wood during the heat treatment process. Both ends of the threaded rod 22 are rotatably connected to the inside of the installation box 20 to ensure the stability of the threaded rod 22 during rotation. At the same time, through the threaded connection with the threaded sleeve 23, the horizontal movement of the threaded sleeve 23 is realized. The squeezing roller 26 is in contact with the silica gel water absorption layer 27, and the silica gel water absorption layer 27 is squeezed by rolling to help squeeze out the absorbed moisture, thereby improving the dehumidification efficiency.

[0038] Working principle: Pull the handle 31 to open the sealed door 2, push the reset block 16 to one side to drive the reset plate 15 to move synchronously, and at the same time drive the limit plate 9 to squeeze the telescopic rod 13 and the spring 14. At this time, the clamping block 11 is completely retracted into the fixed block 8. At this time, the wood is inserted into the groove inside the fixed block 8, and the reset block 16 is released. At this time, the spring 14 is reset and pushes the limit plate 9 to reset under the action of the telescopic rod 13, and at the same time pushes the reset block 16 and the clamping block 11 to move outward until the clamping block 11 clamps the wood and closes the sealed door 2. Then start the motor 5 to drive the support plate 6 and the rotating shaft 7 to rotate synchronously, and then drive the wood to rotate slowly. The heating tube 3 is started through the controller 4 to achieve all-round drying of the wood. When the moisture on the wood is dried, it will turn into water vapor. When too much moisture accumulates, it will condense into water vapor. When more water vapor accumulates The drying speed is affected, so that the temperature inside the kiln body 1 drops. At this time, the inside of the kiln body 1 needs to be dehumidified. The vacuum pump 17 is started to drive the exhaust pipe 18 to extract the moisture inside the kiln body 1 and transport it to the inside of the installation box 20 through the air pipe 19. When moisture and hot air enter the inside of the installation box 20, the silica gel water absorption layer 27 will absorb the moisture, and the dry hot air will pass through the hollow plate 28 and be sent back to the inside of the kiln body 1 through the exhaust pipe 30. When the silica gel water absorption layer 27 is saturated with water, the water needs to be squeezed out. At this time, the motor 21 is started to drive the threaded rod 22 to rotate. The rotation of the threaded rod 22 drives the threaded sleeve 23 to move and then drives the extrusion roller 26 to extrude the silica gel water absorption layer 27, and squeeze the water inside it into the collection box 29. After the extrusion is completed, the handle is pulled to drive the collection box 29 to slide out. At this time, the water in the collection box 29 can be poured out.
