[0028] The protection assembly 8 comprises a moving rod 81 hinged inside the placing groove 7, one end of the moving rod 81 away from the rotating drum 3 is fixedly connected with an L-shaped rod 82, the outer surface of the moving rod 81 is sleeved with a protective film cloth 83, one end of the protective film cloth 83 away from the moving rod 81 is fixedly connected with the inner side wall of the placing groove 7, the top of the support frame 2 is fixedly connected with a fixed frame 85 on the left and right sides, the opposite surfaces of the two fixed frames 85 are fixedly connected with a push rod 86.

[0029] The protection assembly 8 further comprises a torsional spring 84 fixedly connected to the bottom inside the placing groove 7, one end of the torsional spring 84 away from the placing groove 7 is fixedly connected with the bottom of the moving rod 81.

[0030] The protective film cloth 83 is made of PVC transparent film, and the resilience of the torsional spring 84 is greater than the gravity of the moving rod 81.

[0031] By adopting the above technical scheme, when in use, the finished density board is placed on the placing rod 4 from the side, and then the clamping frame 10 is used to clamp the two sides of the top of the density board, so that the density board is dried, and the rotating drum 3 is driven to rotate by the servo motor 5 during the drying process, the rotating of the rotating drum 3 drives the placing rod 4 to rotate, and the rotating of the placing rod 4 drives the density board to rotate, so that the deformation or cracking of the board caused by long-time exposure to the sun is avoided, when the placing rod 4 rotates to the top, the L-shaped rod 82 contacts the push rod 86, so that the L-shaped rod 82 is pushed by the push rod 86 to drive the moving rod 81 to press the torsional spring 84, and then the moving rod 81 slides out of the inside of the placing groove 7 to stretch the protective film cloth 83, and the protective film cloth 83 is stretched to protect the two sides of the placing rod 4, thereby reducing the air flow rate in the upper region, avoiding the rapid loss of moisture in the board caused by the high air flow rate, and greatly reducing the risk of deformation and cracking of the board, when the servo motor 5 drives the rotating drum 3 to continuously rotate, the placing rod 4 is driven to rotate by the rotating of the rotating drum 3, and the moving rod 81 and the L-shaped rod 82 slide in an arc shape after the continuous rotation of the placing rod 4, when the L-shaped rod 82 slides in an arc shape and reaches the bottom of the push rod 86, the push rod 86 loses the pushing of the L-shaped rod 82, the resilience of the torsional spring 84 drives the moving rod 81 to reset, and the protective film cloth 83 is stored in the inside of the placing groove 7, so that the density board is protected when rotating to the top and the air flow is maintained when rotating to other positions, which is beneficial to improve the work efficiency of the density board drying.

[0032] Specifically, as Figs. 2-4As shown, the outer surface of the drum 3 is connected with a cooling assembly 6 at the center, the cooling assembly 6 includes a support rod 61 fixedly connected in an annular array at the center of the outer surface of the drum 3, the support rod 61 is rotatably connected with a gear 62 at the end away from the drum 3, the gear 62 is fixedly connected with a rotating pipe 63 at the side away from the support rod 61, the rotating pipe 63 is communicated with a cooling nozzle 64 at the end close to the drum 3;

[0033] The support rod 61 is internally provided with a through hole 12, which is communicated with the drum 3;

[0034] The support frame 2 is connected with a rotating assembly 9 at the left inner wall, the rotating assembly 9 includes a connecting frame 91 fixedly connected at the left inner wall of the support frame 2, the connecting frame 91 is fixedly connected with a gear ring 92 at the side away from the left inner wall of the support frame 2;

[0035] The gear ring 92 is a semicircular arc, and the gear ring 92 is engaged with the gear 62.

[0036] By adopting the above technical scheme, first, the radiator 11 works to generate airflow, and the support rod 61 and the rotating pipe 63 blow the generated airflow out through the cooling nozzle 64 to blow on the density board, thereby cooling the surface of the density board to reduce the rapid loss of moisture of the density board due to high temperature, further reducing the risk of cracking of the density board during the drying process. Since the cooling range is limited at the top, it will not affect the air flow at the bottom. As the servo motor 5 works to drive the drum 3 to rotate, the gear 62 is engaged with the gear ring 92 to rotate, and the rotation of the gear 62 drives the rotating pipe 63 and the cooling nozzle 64 to rotate, thereby expanding the cooling range. The density board at the bottom not affected by sunlight is dried by rapid air flow, which stabilizes the moisture loss of the density board while improving the drying efficiency of the density board.

[0037] Working principle: when in use, the finished density board is placed on the placing rod 4 from the side, then the clamping frame 10 is used to clamp the two sides of the top of the density board, then the servo motor 5 drives the drum 3 to rotate, the rotation of the drum 3 drives the placing rod 4 to rotate, and the rotation of the placing rod 4 drives the density board to rotate. When the density board rotates to the top, the push rod 86 pushes the L-shaped rod 82, which drives the moving rod 81 to stretch the protection film cloth 83 after pressing the torsional spring 84. After the protection film cloth 83 is unfolded, it has a protective effect on the two sides of the placing rod 4, which avoids the situation that the surface of the density board is damaged due to the loss of moisture after the top wind speed flows through the two sides of the placing rod 4 during the drying process, and is conducive to improving the working efficiency of the density board during the drying process.

[0038] At the same time, the rotation of the drum 3 drives the support rod 61 to rotate. A radiator 11 is provided inside the drum 3. After the radiator 11 works, the gas is transported to the support rod 61. At the same time, the rotation of the support rod 61 drives the gear 62 to rotate. When the support rod 61 rotates to the bottom, the gear 62 is engaged with the ring gear 92, thereby driving the gear 62 to rotate. The rotation of the gear 62 drives the rotating tube 63 to rotate. The rotation of the rotating tube 63 drives the cooling nozzle 64 to rotate, thereby achieving the effect of cooling the density board placed on the top of the placement rod 4 and the support rod 61, avoiding the damage caused by long-term high temperature on the drying surface of the density board, which is beneficial to improving the safety of the density board during the drying process.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
