Mounting plates 103 are symmetrically fixedly installed in the center of the bottom surface of the drying chamber 101, and each mounting plate 103 has a lower opening 104 at both ends of its surface. The inner wall of one lower opening 104 is fixedly fitted with... A guide fan 105 is installed, and a dust cover 106 is fixedly installed on the inner wall of the lower opening 104 below the guide fan 105. The air outlet of the guide fan 105 is positioned away from the dust cover 106. Meanwhile, a guide fan 107 is fixedly installed on the inner wall of the lower opening 104 on the other side, and a dust cover 108 is fixedly installed on the inner wall of the lower opening 104 above the guide fan 107. The air outlet of the guide fan 107 is positioned away from the dust cover 108. Figures 1-2 As shown, dust cover 106 and dust cover 2 108 prevent debris from the surface of the fiberboard from entering the interior of the heating tube 109;

[0030] A heating tube 109 is fixedly installed on the bottom surface of the mounting plate 103. Both ends of the heating tube 109 are respectively connected to each lower opening 104. An electric heating wire 110 is fixedly connected to the inner wall of the heating tube 109.

A hot air fan 114 is fixedly installed on one side of the upper end of the inner wall of the drying oven 101. A guide fan 115 is fixedly installed on the upper end of the inner wall of the drying oven 101, away from the hot air fan 114. The outlet of the hot air fan 114 faces inwards towards the interior of the drying oven 101, while the outlet of the guide fan 115 faces outwards towards the exterior of the drying oven 101. Figure 2 As shown, hot air is introduced into the drying chamber 101 by the hot air blower 114, while the air guide fan 115 draws out the hot air from the drying chamber 101, thereby ensuring the circulation of hot air inside the drying chamber.

[0032] The side of the drying oven 101 is also fixedly installed with the electric cylinder 112, and a positioning cylinder 111 is fixedly installed on the side of the drying oven 101 at the end away from the electric cylinder 112.

[0033] The support mechanism 2 includes a top plate 201. A cover plate 202 is movably installed in the center of the top surface of the top plate 201. Holding rods 203 are fixedly connected to both sides of the top surface of the cover plate 202. An extension plate 204 is fixedly installed on the bottom surface of the top plate 201, below the cover plate 202. A support plate 205 is fixedly connected to the bottom end of the extension plate 204. An extension opening 206 is provided on the surface of the extension plate 204, and the extension opening 206 is aligned with the length direction of the extension plate 204.

Figure 2 , Figure 4 As shown, the guide rod 208 moves along the inner wall of the positioning cylinder 111, thereby ensuring the stability of the top plate 201 during lifting and lowering.

[0035] The working principle of this utility model:

[0036] When using the device, lift the holding rod 203 and separate the cover plate 202 from the top plate 201. Then, insert the fiberboard into the interior of each extension plate 204. After that, install the cover plate 202 above the top plate 201. Next, start the air guide fan 105, air guide fan 207, air guide fan 315 and hot air fan 114. Hot air is input into the drying chamber 101 by the hot air fan 114. Then, the hot air passes through the air guide fan 2107 and enters the heating tube 109. At this time, the heating wire 110 is energized and heats the hot air inside the heating tube 109. The air guide fan 105 guides the hot air from the heating tube 109 into the drying chamber 101. Finally, the air guide fan 3 exhausts the hot air from the drying chamber 101. Following the above process, the hot air circulates between each fiberboard and the partition 113, so that each side of the fiberboard can be in uniform contact with the hot air.

[0037] Secondly, after the fiberboard is dried, the electric cylinder 112 pushes the top plate 201 to rise and cools the inside of the drying chamber 101. The holding rod 203 is pushed upward and the cover plate 202 is separated from the top plate 201. Then, the fiberboards are taken out one by one from the inside of the extension plate 204.

[0038] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
