The second motor drives the rotating shaft and the placing plate to rotate, thereby driving the medium density fiberboard to rotate, which can realize automatic turning of the medium density fiberboard, and drive the air flow in the inner cavity of the box body, making the temperature inside the box more uniform.

[0004] However, most of the existing drying devices are difficult to adjust the spacing and are difficult to be applicable to plates of different sizes and thicknesses. Moreover, the air flow in the existing drying device is slow, which affects the drying rate. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a glue-free medium density fiberboard drying device that can not only be applicable to fiberboards of different thicknesses and lengths, improve the flexibility of the device, but also accelerate the air flow in the device, improve the drying effect, and timely discharge the moisture.

[0006] A glue-free medium density fiberboard drying device of the present utility model includes a heating mechanism; it also includes a rotating mechanism, a telescopic mechanism, two sets of clamping mechanisms, and a drainage mechanism. The rotating mechanism is installed on the heating mechanism and drives the fiberboard to rotate.

The staff fixes the fiberboard between the two sets of clamping mechanisms, can adjust the two sets of clamping mechanisms according to the different thicknesses of the fiberboard, and at the same time uses the telescopic mechanism to adjust the distance between the two sets of clamping mechanisms, which is convenient for adapting to fiberboards of different lengths. Then the heating mechanism heats and dries the fiberboard. At the same time, the rotating mechanism drives the fiberboard to rotate, making the fiberboard evenly heated, and starts the drainage mechanism to accelerate the air flow in the device, enhance the drying effect, and timely discharge the moisture in the device.

The three groups of springs are respectively sleeved on the three groups of telescopic rods. The connecting frame two is installed on the turntable. One end of the two sets of fixed rods is connected to the connecting frame two, and the other end is connected to the connecting frame one. The connecting frame one drives the connecting frame two and the turntable to rotate through the two sets of fixed rods, enhancing the synchronism between the turntable and the transmission shaft, avoiding the fiberboard from receiving longitudinal bending force. By setting the three groups of telescopic rods and the three groups of springs, it is convenient to adapt to fiberboards of different lengths and improves the flexibility of the device.

[0010] Preferably, the clamping mechanism includes a tray, a baffle, multiple moving plates, a sliding plate and a lock.

The electric resistance wire heats and dries the fiberboard. The fiberboard emits moisture when heated. The humid air accumulates at the bottom end inside the cavity of the cylinder body. The air pump is started. The air pump extracts the air at the bottom of the cavity of the cylinder body through the air extraction pipe, and then conveys the humid air to the heat preservation box through the first air delivery pipe. The limestone absorbs the moisture in the air and emits a large amount of heat. Then the valve two is opened. The dried air enters the cavity of the cylinder body again through the second air delivery pipe, accelerating the air flow inside the device. When the drying is completed, the valve two is closed.
