[0035] During use, the one end of the air pipe 1 away from the mounting hole 301 is communicated with the external air supply device, which provides cold air to the air pipe 1.

[0036] In the utility model one specific embodiment, air inlet assembly still includes coaxial first circular plate 9 and second circular plate 10, and the opposite face of first circular plate 9 and second circular plate 10 is in contact with each other, and the through hole 901 corresponding with blind hole 302 is formed in first circular plate 9, and first circular plate 9 is fixed on the bottom wall of mounting hole 301, and specifically, the counterbore is formed in first circular plate 9, and the screw is arranged in the counterbore, and the screw is threadedly connected with the bottom wall of mounting hole 301, and the semicircular through hole 1001 communicating with the inner cavity of air pipe 1 is formed in second circular plate 10, and the semicircular through hole 1001 is located in the upper half of second circular plate 10, and the lower surface of the inner wall of air pipe 1 is fixed with semicircular plate 101, and second circular plate 10 is in contact with the end surface of air pipe 1, and the lower half of second circular plate 10 is fixedly connected with semicircular plate 101, and specifically, the counterbore is formed in the lower half of second circular plate 10, and the screw is arranged in the counterbore, and the screw is threadedly connected with semicircular plate 101.

[0037] When using, since only the density plate 6 is arranged on the supporting rod 5 of the upper half of main shaft 3, the cold air does not need to be provided to the supporting rod 5 of the lower half of main shaft 3, air pipe 1 is rotationally connected with mounting hole 301, and the semicircular through hole 1001 on second circular plate 10 and the through hole 901 on first circular plate 9 are periodically connected and disconnected with the rotation of main shaft 3, so that the purpose of providing cold air to only the supporting rod 5 on the upper half of main shaft 3 is realized, which is beneficial to reducing the burden of air supply device, saving energy and cold air.

[0038] In the utility model one specific embodiment, first circular plate 9 and second circular plate 10 are both ceramic material or Teflon material. The ceramic material has the advantages of high hardness, smooth surface and wear resistance, and the Teflon material has the advantages of wear resistance, self-lubrication and low friction coefficient.

[0039] In the utility model one specific embodiment, the threaded hole is formed in the circumferential surface of main shaft 3, the threaded hole is threadedly connected with supporting rod 5, and the threaded fastening glue is arranged at the connecting position, and the air channel 303 communicating with blind hole 302 is formed in the bottom wall of threaded hole. The threaded fastening glue is arranged to firmly connect supporting rod 5 and threaded hole, so that supporting rod 5 is prevented from loosening during use.

[0040] In the specific embodiment of the utility model, the central axis of the air outlet hole 501 is parallel to the central axis of the main shaft 3, which ensures that the cold air blown can sweep across the surface of the density board 6, thereby taking away the heat of the density board 6 (in actual application, the interval between each group of support rods 5 is much smaller than that in the drawing, and the parallelism between the central axis of the air outlet hole 501 and the central axis of the main shaft 3 can make the air blown from the air outlet hole 501 exchange heat with the density boards 6 on both sides of the support rod 5 at the same time, thereby improving the utilization rate of the cold air). Obviously, the central axis of the air outlet hole 501 can have a certain angle with the central axis of the main shaft 3, but it is best not to make the air outlet hole 501 face the density board 6, otherwise the density board 6 will block the air outlet hole 501 during the overturning process.

[0041] The working principle of the cooling device for density board production is as follows: when the device is started, the speed reducer 4 drives the main shaft 3 to rotate through the driving wheel, the driven wheel and the belt or chain transmission. At the same time, an external air supply device such as a cold air unit or an air compressor delivers cold air into the air pipe 1 of the air inlet assembly. Since the air pipe 1 is rotationally connected with the mounting hole 301 at one end of the main shaft 3, the first circular plate 9 is fixed on the bottom wall of the mounting hole 301, the through hole 901 thereon is in communication with the blind hole 302, the second circular plate 10 is fixed on the air pipe 1, the semicircular through hole 1001 in the upper half portion thereof is in communication with the air pipe 1, and the semicircular through hole 1001 and the through hole 901 will be periodically connected and disconnected with the rotation of the main shaft 3. During the rotation of the main shaft 3, when the semicircular through hole 1001 and the through hole 901 are connected, the cold air enters the corresponding blind hole 302, then passes through the air channel 303 into the inner cavity of the support rod 5, and finally is blown out from the air outlet hole 501. The blown cold air exchanges heat with the density board 6, thereby cooling the density board 6, and thus improving the cooling efficiency of the density board 6.

[0042] The embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same or similar parts between the embodiments can be referred to each other, and the embodiments can be combined with each other.

[0043] The above embodiments only describe the preferred modes of the utility model, and do not limit the scope of the utility model. Without departing from the design spirit of the utility model, various modifications and improvements of the technical solutions of the utility model made by those skilled in the art shall fall within the protection scope determined by the claims of the utility model.
