[0024] In this embodiment: by arranging two parallel double-speed chains 4 along the length direction inside the rectangular frame 3, the two ends of the plywood are placed on the double-speed chains 4 on both sides, so that the double-speed chains 4 can stably transport the plywood into the drying chamber 1. When the plywood is transported to the position of the turning mechanism 5 (that is, when the plywood moves to the first turning frame 6), the motor 11 is started, the first rotating shaft 8 and the second rotating shaft 9 rotate (the rotation speed of the second rotating shaft 9 lags behind the rotation speed of the first rotating shaft 8), driving the first turning frame 6 and the second turning frame 7 to rotate relative to each other. While the first turning frame 6 rotates, the plywood is lifted up, and the plywood is separated from the double-speed chains 4, and the plywood slides into the plate placement groove 10. When the angle of the first turning frame 6 is greater than 90 degrees, the plywood in the plate placement groove 10 on the first turning frame 6 falls into the storage groove of the second turning frame 7, thereby realizing the automatic turning function of the plywood.

[0027] In this embodiment: the two second turning frames 7 are located on both sides of the first turning frame 6, the second support plate 13 and the first support plate 12 have the same width, the first support plate 12 and the second support plate 13 increase the contact area between the first turning frame 6 and the second turning frame 7 and the plywood, making it easy to stably turn the plywood.

[0028] As a technical optimization solution of the utility model, air distribution plates 14 are provided at the top and bottom of the drying chamber 1, an air distribution cavity 15 is provided inside the air distribution plate 14, and air distribution ports 16 connected to the air distribution cavity 15 are evenly arranged on the air distribution plate 14.

[0029] In this embodiment, an air distribution cavity 15 is provided in the air distribution plate 14, and hot air flows out from a plurality of air distribution ports 16 through the air distribution cavity 15, which is beneficial to uniform drying of the plywood.

[0031] In this embodiment: the heating wire 19 inside the heating chamber 17 is powered on for heating, and the fan 18 is started. The fan 18 pumps the heat inside the heating chamber 17 into the drying chamber 1, and the hot air flows out evenly from the air distribution port 16, so that the hot air inside the drying chamber 1 is evenly distributed. At the same time, the wind flows relatively upward and downward, which speeds up the efficiency and quality of plywood drying.

The temperature controller 21 is electrically connected to the temperature sensor 20 , the heating chamber 17 and the fan 18 .

[0033] In this embodiment, the temperature sensor 20 detects the temperature in the drying chamber 1 in real time, and can control the internal temperature of the drying chamber 1 when the temperature is too high or too low.

[0034] As a technical optimization solution of the present utility model, a visual window 22 is provided on the drying chamber 1 .

[0037] When the plywood moves to the first turning frame 6, the motor 11 is started, the first rotating shaft 8 and the second rotating shaft 9 rotate, driving the first turning frame 6 and the second turning frame 7 to rotate relative to each other. While the first turning frame 6 rotates, the plywood is lifted up, and the plywood is separated from the speed chain 4, and the plywood slides into the plate placement groove 10. When the angle of the first turning frame 6 is greater than 90 degrees, the plywood in the plate placement groove 10 on the first turning frame 6 falls into the storage groove of the second turning frame 7, realizing the automatic turning function of the plywood;

[0038] After flipping, the first flip frame 6 and the second flip frame 7 continue to rotate in opposite directions. When the second flip frame 7 moves into the rectangular frame 3, the plywood in the storage groove on the second flip frame 7 is overlapped on the double-speed chain 4, and the double-speed chain 4 continues to transport the plywood. The plywood is transported and flipped in the drying chamber 1, which makes it easy for the plywood to be evenly heated and dried.
