[0028] The supporting unit includes a rotating rod 501 and a first supporting rod 502; the rotating rod 501 is rotatably installed at the bottom of the conveying plate 2, and the rotating rod 501 is used to drive the first supporting rod 502 to rotate; the first supporting rod 502 is fixed to the outer wall of the rotating rod 501 and is located on the outer side of the conveying plate 2, and the first supporting rod 502 is used to provide supporting force for the prefabricated components.

[0029] The transmission unit includes a first gear 503, a rotating wheel 504, a transmission rod 505, and a first rack 506; the first gear 503 is fixed to one end of one rotating rod 501, and the first gear 503 is used to drive the rotating rod 501 to rotate; the rotating wheel 504 is fixed to the other end of each rotating rod 501, and the rotating wheel 504 is used to drive the end of the transmission rod 505 to rotate in the circumferential direction; the transmission rod 505 is eccentrically connected to the outer wall of the rotating wheel 504, and the transmission rod 505 is used to drive each rotating wheel 504 to rotate. The first rack 506 is fixed to the inner side of the curing kiln shell 1, and the first rack 506 is used to provide a rotational force for the rotation of the first gear 503.

[0030] The positioning unit includes a second support rod 601 and a second rack 602; the second support rod 601 is fixed to the top of the conveying plate 2, and the second support rod 601 is used to provide support for the sealing door 4; the second rack 602 is fixed to one side of the second support rod 601, and the second rack 602 is used to provide power for the rotation of the second gear 603.

[0031] The sealing unit includes a second gear 603, a third gear 604, and a third rack 605; the second gear 603 is rotatably installed on the inner side of the curing kiln shell 1, and the second gear 603 is used to synchronously drive the third gear 604 to rotate; the third gear 604 is rotatably installed inside the curing kiln shell 1 and meshes with the second gear 603, and the third gear 604 is used to drive the third rack 605 to move; the third rack 605 is fixed on the outer wall of the sealing door 4, and the third rack 605 is used to synchronously drive the sealing door 4 to move.

[0032] In this embodiment: in the initial state, the conveying plate 2 moves out of the curing kiln shell 1, and the sealing door 4 is in an open state and supported by the second support rod 601. When using this device, the prefabricated components to be cured are placed on the upper surface of the conveying plate 2. At this time, the upper surface of the conveying plate 2 is flat, and the placement process will not affect the prefabricated components; then the conveying plate 2 can be pulled into the interior of the curing kiln shell 1 by the cylinder 3. Since the length of the support rod 601 is greater than that of the conveying plate 2, after the conveying plate 2 completely enters the interior of the curing kiln shell 1, the second support rod 601 and the second rack 602 fixed on the outer wall of the conveying plate 2 will gradually approach the second gear 603. At this time, the rubber pad part on the second support rod 601 will also gradually contact with the sealing door 4. When the second rack 602 contacts the upper side of the second gear 603, it drives the second gear 603 to rotate clockwise. The clockwise rotating second gear 603 synchronously drives another second gear 603 to rotate. The other second gear 603 engages and drives the third gear 604 to rotate counterclockwise, thereby giving the third rack 605 a thrust to move downward, so that the third rack 605 synchronously drives the sealing door 4 to move downward. The sealing door 4 moving downward will give pressure to the rubber pad on the outer wall of the second support rod 601, so that the rubber pad at this position is deformed, until the second support rod 601 is no longer in contact with the sealing door 4 as the conveying plate 2 moves. At this time, the sealing door 4 will also descend normally to complete the closing operation, thereby playing a role in sealing the curing kiln shell 1.

[0033] When the maintenance is completed, the cylinder 3 is started again to push the conveying plate 2 out. The conveying plate 2 drives the second rack 602 on the support rod 601 to contact the second gear 603 first, thereby giving the third gear 604 a rotational thrust, so that the third gear 604 gives the third rack 605 an upward thrust, so that the sealing door 4 fixed with the third rack 605 is lifted first.

[0034] The continued movement of the conveying plate 2 will also synchronously drive the first gear 503 to contact the first rack 506. Since the first rack 506 is below the first gear 503, the contact between the first gear 503 and the first rack 506 will give the first gear 503 a clockwise rotation thrust. When the conveying plate 2 enters the curing kiln shell 1, the first gear 503 is meshed with the first rack 506, and will synchronously drive the rotating rod 501 and the first support rod 502 to rotate clockwise, so that the first support rod 502 can hold up the prefabricated component above it and keep a certain distance from the conveying plate 2, thereby increasing the contact area between the prefabricated component and the hot air inside the curing kiln shell 1. When the conveying plate 2 is removed from the curing kiln shell 1, the first support rod 502 moves in the opposite direction and re-enters the groove 507, so that the prefabricated component lands smoothly, avoiding damage to the prefabricated component due to a large impact force and facilitating the removal and placement, thereby improving the quality and efficiency of curing.

[0035] Please refer to Figure 1-Figure 6 , there are multiple rotating rods 501 and first support rods 502, which are evenly distributed on the outer wall of the conveying plate 2, and a groove 507 for the first support rod 502 to enter is formed on the upper top surface of the conveying plate 2. When the first support rod 502 is in the groove 507, the upper surface of the first support rod 502 is flush with the upper surface of the conveying plate 2; a support block 508 is provided on the side wall of the conveying plate 2, and there are multiple rotating wheels 504, which are all fixedly connected to the end of a rotating rod 501, and the connection point between the transmission rod 505 and each rotating wheel 504 is at the same distance from the axis of the rotating wheel 504.

[0036] In this embodiment: through this structure, after a first gear 503 contacts the first rack 506, a rotation thrust is given to the first gear 503, which drives the rotating rod 501 to rotate synchronously, so that the rotating wheel 504 at the other end of the rotating rod 501 rotates synchronously, and drives a connection point of the transmission rod 505 to move along the outer wall of the rotating wheel 504, thereby synchronously driving other rotating wheels 504 and the transmission rod 505 to rotate synchronously, so that multiple first support rods 502 are rotated by ninety-five degrees, and a support block 508 is set at the position after rotation, and the block is fixed on the outer wall of the conveying plate 2. This design enables the first support rod 502 to lift the prefabricated component, provide support for the prefabricated component, and increase the heating and ventilation area of ​​the prefabricated component.

[0037] Please refer to Figure 1-Figure 6 There are two second gears 603, and the two second gears 603 are coaxially fixedly connected by a connecting shaft. The upper part of one second gear 603 is meshed with the second rack 602, and the other second gear 603 is meshed with the outer wall of the third gear 604, wherein the third gear 604 and the second rack 602 are staggered and do not contact each other.

[0038] In this embodiment: through the above structure, a second gear 603 can be driven to rotate by the second rack 602, and then another second gear 603 can rotate synchronously and can drive the third gear 604 to rotate together. The rotating third gear 604 can engage and drive the third rack 605 to rise and fall, and at the same time drive the sealing door 4 to rise and fall.

[0039] Please refer to Figure 1-Figure 2 The second support rod 601 is in an inverted U shape, and the length of one end of the second support rod 601 on which the second rack 602 is installed exceeds the length of the conveying plate 2 on that side; the vertical rod at one end of the second support rod 601 on which the second rack 602 is installed is arranged in an inclined shape, and the inclined vertical rod on this side is fixed to the conveying plate 2 through a connecting rod; a deformable rubber pad is arranged at the connection between the vertical rod and the cross rod on this side, and the rubber pad can be deformed under force during the downward movement of the sealing door 4.

[0040] In this embodiment, when the conveying plate 2 located inside the curing kiln shell 1 moves outward, the second support rod 601 drives the second rack 602 to approach the sealing door 4 before the conveying plate 2. At this time, the second rack 602 first contacts the upper part of a second gear 603, and then engages the third gear 604 in turn through another synchronously rotating second gear 603 to rotate. The rotating third gear 604 can engage and drive the third rack 605 to lift the sealing door 4; the vertical rod close to the sealing door 4 and inclinedly arranged can provide support and guidance for the sealing door 4, and the setting of the rubber pad can make the movement of the sealing door 4 from the horizontal rod to the vertical rod position smoother and gentler.

[0041] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
