[0002] With the development of wood processing industry, wood drying technology has become one of the key steps to ensure wood quality and improve wood utilization. Wood needs to be properly dried before processing to remove excess moisture inside and prevent deformation, cracking and other problems in the subsequent use of wood.
[0003] Although the common wood drying equipment on the market can significantly improve the drying efficiency, there are still some problems that need to be solved in actual operation. For example, when drying wooden boards, they are usually manually stacked on pallets and wooden strips are placed between every two wooden boards to ensure that air can flow smoothly between the wooden boards and promote the evaporation of moisture. Although this method is simple and easy to implement, it also has obvious shortcomings: due to the presence of wooden strips, the parts of the wooden boards that are directly in contact with the wooden strips are difficult to obtain sufficient hot air flow, resulting in a slower evaporation rate of moisture in these areas, and ultimately causing uneven drying of the entire wooden board. This uneven drying not only affects the quality of the wood, but may also lead to dimensional instability in the subsequent processing process. In order to minimize the phenomenon of uneven drying, operators usually extend the drying time, which will undoubtedly increase production costs and reduce work efficiency. Summary of the invention

The number of the connecting plates 25 is four, and the four connecting plates 25 are all located in the front and lower part of the box door 102, which does not affect the normal opening and closing of the box door 102. The four connecting plates 25 are all rotatably connected to the positioning wheel 26.
[0030] like Figure 1-Figure 10 As shown, the present invention also provides a drying method of wood drying equipment with efficient heat utilization, which specifically includes the following steps:
[0031] First, place the wooden board vertically on the placement groove 201 of the movable tray 2. The wooden board will squeeze the contact block 15 to move downward, so as to drive the stabilizing rod 14 to rotate on the connecting rod 13, and the torsion spring 16 will twist accordingly. The lower end of the stabilizing rod 14 and the contact block 15 will enter the storage groove 202 until the contact block 15 moves to the arc surface 204. The arc surface 204 is used to prevent the contact block 15 from being blocked by the bottom of the placement groove 201. Since the wooden board has just been cut, there may be wood chips on the side of the wooden board, and the wood chips that fall into the middle of the placement groove 201 can fall into the through hole 203 along the arc surface 204 and fall down to the ground through the through hole 203, thereby preventing the wood chips from accumulating in the middle of the placement groove 201 and blocking the contact block 15. At this time, the upper ends of the two stabilizing rods 14 in the same group will move to the left and right sides of the wooden board respectively, and at the same time, the stabilizing rod 14 will drive the protrusion 19 to rotate upward. When the protrusion 19 contacts the top block 18, the top block 18 will squeeze the protrusions on the left and right sides. The block 19 moves toward the direction close to the wooden board, and the protrusion 19 can drive the stabilizing rod 14 to move toward the direction close to the wooden board on the connecting rod 13, so that the two stabilizing rods 14 in the same group can clamp the wooden board. At this time, the torsion spring 16 will be stretched due to the tension; at this time, the box door 102 can be manually rotated forward to open, and then the mobile tray 2 can be moved into the box body 101, and the positioning wheel 26 can guide and position the mobile tray 2, so that the mobile tray 2 can accurately enter the box body 101, which can prevent the mobile tray 2 from colliding with the box body 101. The mobile tray 2 can drive the wooden board into the box body 101, so that the wooden board is located under the wedge block 10. Under the stabilizing effect of the stabilizing rod 14, the wooden board can be prevented from tipping over, and then the box door 102 is rotated backward to be closed and locked, and then the air pump 20 is controlled to inflate the air bag 24 through the connecting pipe 22, and the air bag 24 will expand to block the gap between the box body 101 and the box door 102, so as to seal and prevent the hot air inside the box body 101 from overflowing;Then, one group of the first electric push rods 3 is controlled to drive the frame 4, the mounting rod 5, the guide rod 6, the moving block 7 and the wedge block 10 to move downward. When the wedge block 10 contacts the wooden board, the wedge block 10 will move under the action of the inclined surface, so that each wedge block 10 is located on the left and right sides of each wooden board respectively. The wedge block 10 will drive the moving block 7 to move on the guide rod 6, and the connecting spring 8 will deform adaptively until each moving block 7 is located on the left and right sides of each wooden board. Then, the second electric push rod 11 is used to drive the rightmost moving block 7 and the leftmost moving block 7 to move toward the side close to each other, so that each moving block 7 can clamp each wooden board through the top teeth 9. Then, the first electric push rod 3 drives the frame 4, the mounting rod 5, the guide rod 6, the moving block 7 and the wedge block 10 move upward for a distance, the moving block 7 can drive each wooden board to move upward through the top tooth 9, at this time the wooden board will be separated from the contact block 15, the torsion spring 16 will reversely twist and recover due to its own elasticity, so as to drive the stabilizing rod 14 to reverse and reset on the connecting rod 13, the lower end of the stabilizing rod 14 can drive the contact block 15 to move upward and separate from the storage groove 202, and the stabilizing rod 14 can drive the protrusion 19 to move downward and separate from the top block 18, at this time the torsion spring 16 will shrink and recover due to its own elasticity, so as to drive the stabilizing rod 14 to move and reset on the connecting rod 13 away from the wooden board, the stabilizing rod 14 will loosen the wooden board, and since the rising distance of the wooden board is greater than the depth of the placement groove 201, the wooden board will be separated from the placement groove 201, and the wooden board in the box The wood board in the box body 101 is in a suspended state, and then the high-temperature heat pump unit 103, the dehumidifier 104 and the circulating fan unit 105 work together to dry the wood board in the box body 101; after 2 hours, repeat the above operation, the moving block 7 of the other group can be controlled to descend and clamp the wood board through the top teeth 9, and then the second electric push rod 11 of the previous group is controlled to drive the rightmost moving block 7 and the leftmost moving block 7 to move away from each other and reset, so that the moving block 7 of the previous group can release the wood board, and then the first electric push rod 3 of the previous group is controlled to drive the frame 4, the mounting rod 5, the guide rod 6, the moving block 7 and the wedge block 10 to move upward and reset until the wedge block 10 of the previous group is separated from the wood board, so that the two groups of moving blocks 7 can be alternately The wooden board is clamped in this way, and the cycle operation can be alternated every two hours, so that the contact part between the top teeth 9 on the previous group of moving blocks 7 and the wooden board can also be dried well, which can improve the drying effect and the overall drying efficiency; when the wooden board is dried, the moving block 7 can be controlled to move downward, and the moving block 7 can put the wooden board back into the placement groove 201 through the top teeth 9, and then the box door 102 is opened, and the moving tray 2 is pulled out, and the dried wooden board can be taken out from the box 101, and finally the air in the airbag 24 can be discharged through the exhaust valve 23 to make the airbag 24 shrink and recover. It should be noted that the temperature in the box 101 is lower than 100 degrees Celsius, so the operation of the first electric push rod 3 will not be affected. ;

Then, one of the first electric push rods (3) is controlled to drive the frame (4), the mounting rod (5), the guide rod (6), the movable block (7) and the wedge block (10) to move downward until each movable block (7) is located on the left and right sides of each wooden board. Then, the second electric push rod (11) drives the rightmost movable block (7) and the leftmost movable block ( 7) move toward one side close to each other, so that each moving block (7) can clamp each wooden board through the top teeth (9), and then the first electric push rod (3) drives the frame (4), the mounting rod (5), the guide rod (6), the moving block (7) and the wedge block (10) to move upward for a certain distance. The moving block (7) can drive each wooden board to move upward through the top teeth (9), so that the wooden board will separate from the contact block (15), and the stabilizing rod (14) will move away from the wooden board to reset, so as to release the wooden board, and the wooden board will also be separated from the placement groove ( 201) is disengaged, and then the high-temperature heat pump unit (103), the dehumidifier (104) and the circulating fan unit (105) cooperate to dry the wooden board in the box body (101). After a period of time, the moving blocks (7) of another group can be controlled to descend and clamp the wooden board through the top teeth (9), and then the upper group of moving blocks (7) can be controlled to release the wooden board. In this way, the wooden board can be clamped alternately by the two groups of moving blocks (7), so that the contact part between the top teeth (9) on the upper group of moving blocks (7) and the wooden board can also be dried.
