[0014] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1-5 The wood compaction and air-cooling device shown includes a frame 1, on which a hydraulic press 2 is fixedly mounted by bolts. The output end of the hydraulic press 2 is set vertically downward. A processing table 4 is installed on the frame 1 directly below the output end of the hydraulic press 2. An air-cooling circulation mechanism 3 is connected below the output end of the hydraulic press 2, so that the air-cooling circulation mechanism 3 rises and falls synchronously with the output end of the hydraulic press 2.

[0016] The air-cooled circulation mechanism 3 includes a housing 31, which is fixed below the output end of the hydraulic press 2 via a flange structure. Air vents 33 are provided on both sides of the outer wall of the housing 31. The air vents 33 are used to realize the air exchange between the inside and outside of the housing 31. An installation plate 310 is fixed inside the housing 31 by bolts. A uniformly distributed circulating fan 311 is fixedly installed on the installation plate 310. The circulating fan 311 provides power for air circulation. A pressure plate 32 is fixed to the bottom of the housing 31 by welding. The pressure plate 32 corresponds to the processing table 4 and is used to press the wood. A uniform air cavity plate 35 is fixed on both sides of the pressure plate 32 by bolts. The uniform air cavity plate 35 has a hollow structure inside and is connected to the inside of the housing 31 through several air pipes 34. The air pipes 34 are used to conduct the airflow inside the housing 31 to the uniform air cavity plate 35.

[0017] A movable cavity cylinder 352 is rotatably mounted inside the air distribution cavity plate 35 via a pair of mounting blocks 351. The mounting blocks 351 are welded and fixed to the inner wall of the air distribution cavity plate 35. The two ends of the movable cavity cylinder 352 are rotatably engaged with the mounting blocks 351 via rotating shafts, allowing the movable cavity cylinder 352 to rotate around the mounting blocks 351. A pair of rectangular long air inlets 353 are oppositely opened on the outer wall of the movable cavity cylinder 352, through which airflow can be discharged or introduced. Evenly distributed drive rollers 41 are rotatably mounted on the processing table 4 via bearings. The drive roller 41 is used to support and convey timber. A partition 37 is fixed inside the housing 31 by welding. The partition 37 divides the interior of the housing 31 into a first air chamber 38 and a second air chamber 39. The interior spaces of the first air chamber 38 and the second air chamber 39 are divided into an air inlet chamber and an air outlet chamber by a mounting plate 310. The air inlet chamber and the air outlet chamber of the first air chamber 38 and the second air chamber 39 are arranged in opposite directions. That is, when the upper part of the first air chamber 38 is the air inlet chamber and the lower part is the air outlet chamber, the upper part of the second air chamber 39 is the air outlet chamber and the lower part is the air inlet chamber.

[0018] In use, the wooden board is placed on the drive roller 41 via the pallet. The drive roller 41 rotates and moves the wooden board directly under the pressure plate 32. The hydraulic press 2 drives its output end to move down, which in turn drives the entire air-cooled circulation mechanism 3 to move down synchronously, so that the pressure plate 32 gradually approaches the wood and finally cooperates with the pallet to compact the wood. During this process, the circulating fan 311 starts synchronously, and the air is drawn in and discharged through the air vents 33 on both sides of the casing 31. With the help of the airflow guidance of the upper and lower air chambers, a stable circulating air volume is formed. Because the air inlet and outlet chambers of the first air chamber 38 and the second air chamber 39 are set in opposite directions, when the airflow circulates, the movable cavity cylinder 352 in the air distribution cavity plate 35 on one side discharges the airflow through the rectangular long air outlet 353, and the airflow flows along the periphery of the wood. Meanwhile, the corresponding movable cavity cylinder 352 on the other side guides the airflow flowing along the periphery of the wood into the interior through the rectangular long air outlet 353. The two form a circulating airflow direction with exhaust on one side and air intake on the other side. Based on this airflow circulation structure, the heat on the wood can be quickly removed, which can reduce the time required for the wood to cool down to a certain extent and improve the problem of low efficiency of conventional natural cooling.

[0019] A contact plate 354 is welded to the outer wall of the movable cavity cylinder 352. A switching abutment rod 36 is bolted to each of the four corners of the processing table 4. The switching abutment rod 36 and the contact plate 354 are vertically aligned. The top two sides of the switching abutment rod 36 are designed with arc surfaces to facilitate smooth movement of the contact plate 354. A torsion spring is also provided between the mounting block 351 and the movable cavity cylinder 352. The torsion spring is sleeved on the rotating shaft of the movable cavity cylinder 352. One end of the torsion spring is fixed to the mounting block 351 and the other end is fixed to the movable cavity cylinder 352, providing elastic force for the reset of the movable cavity cylinder 352.

[0020] During the wood pressing process, the contact plate 354, under the pull of the torsion spring, drives the movable cavity cylinder 352 to maintain its initial posture. At this time, the rectangular long air vent 353 on its outer side faces downwards. As the air-cooling circulation mechanism 3 gradually descends under the drive of the hydraulic press 2, when the lower surface of the inclined contact plate 354 contacts the arc structure at the top of the switching rod 36, the air-cooling circulation mechanism 3, which continues to descend, will cause the contact plate 354 to be pushed by the switching rod 36. Since the switching rod 36 is a rigid structure, its pushing force overcomes the elastic force of the torsion spring, causing the movable cavity cylinder 352 to flip upwards around the mounting block 351. This flipping process gradually changes the rectangular long air vent 353, which was originally facing diagonally downwards, to a horizontal orientation, thus precisely aligning it with the two sides of the wood surface. This allows the airflow to directly act on the sides of the wood, improving the cooling effect. After the wood is compacted, the hydraulic press 2 drives the air-cooling circulation mechanism 3 to rise upwards. The contact plate 354 gradually breaks free from the constraint of the switching rod 36. The movable cavity cylinder 352, which has lost its pushing force, returns to its initial posture under the elastic pull of the torsion spring, once again placing the rectangular long air vent 353 in a diagonally downward position. At this time, the air-cooling circulation mechanism 3 has risen to a certain height, and the diagonally downward orientation of its rectangular long air vent 353 is precisely aligned with the wood below, ensuring that the airflow can still accurately act on the wood surface, continuously carrying away residual heat, thereby ensuring the overall heat dissipation effect.

[0021] The working principle of the air-cooling device for high-frequency compaction of this type of timber is as follows: The wood to be processed is placed on the drive roller 41 of the processing table 4 via a pallet. The drive roller 41 rotates, conveying the wood to the area directly below the pressure plate 32. The hydraulic press 2 is started, and its output drives the air-cooled circulation mechanism 3 to move downwards, causing the pressure plate 32 to cooperate with the pallet to compact the wood. Simultaneously, the circulating fan 311 is started. With the help of the first air chamber 38 and the second air chamber 39 separated by the partition 37 inside the machine housing 31, and in conjunction with the air pipe 34 and the air distribution cavity plate 35, air is exhausted through the rectangular long air outlet 353 of the movable cavity cylinder 352 on one side, and air is drawn in from the other side, thus forming an airflow circulation that acts on the surface of the wood, carrying away the heat from the wood. When the air-cooling circulation mechanism 3 moves downward, the switching rod 36 pushes the contact plate 354, causing the movable cavity cylinder 352 to rotate, so that the rectangular long air outlet 353 is horizontally aligned with both sides of the wood, limiting the airflow range and thus improving the heat dissipation effect. When the hydraulic press 2 drives the air-cooling circulation mechanism 3 to rise, the contact plate 354 disengages from the switching rod 36, and the movable cavity cylinder 352 is reset under the action of the torsion spring, so that the rectangular long air outlet 353 faces diagonally downward, and is aligned with the wood again, still able to dissipate heat from the wood surface. After cooling is completed, the transmission roller 41 conveys the wood to the next process, completing the air-cooling treatment after the wood is compacted.
