After nearly 30 years of development, China's wood floor industry has made remarkable progress in technological innovation and brand establishment, and has now formed a relatively complete industrial system. In recent years, after reaching a historical peak, China's wood floor production has shown a slow downward trend, and the benefits of most products in this field have declined, making the industrial development situation severe. Science is the primary driving force for industry development. Only by continuously innovating and bringing forth new ideas from the direction of people's needs can the wood floor industry break the current predicament.

[0003] In recent years, the trend of national fitness and home fitness has become popular.

To meet the high-quality sports area needs of people, highly elastic floors urgently need to be innovatively developed, and such floors enable the floor boards to quickly become highly elastic hard solids when people are engaged in intense sports or sports competitions.

[0004] However, in the process of processing high-elastic wood-based panels, agents such as polydimethylsiloxane are required. Such agents play a key role in constructing the crosslinked network, but they are also prone to oxidation during long-term high-temperature drying, thereby affecting the construction effect of the crosslinked network. Therefore, a special device with low temperature and high drying efficiency needs to be designed for the drying link of high-elastic wood-based panels. Content of the Utility Model

[0023] A high-elastic artificial board drying device, especially for drying operations when the raw material of the artificial board used is wood fiber (such as wood fiber filaments, etc.), such as Figure 1As shown in the figure, it includes a device body 1. Inside the device body 1, there is a centrifugal drying turntable 21. The centrifugal drying turntable 21 is connected to a centrifugal motor 24 through a coupling and is driven by it to rotate. That is, the direct drive method can better control the timely speed of the centrifugal drying turntable 21. In this embodiment, the centrifugal motor 24 is a variable-frequency motor (or a motor with adjustable speed). A number of drying air holes 3 are provided on the centrifugal drying turntable 21; a drying air chamber 2 is provided below the centrifugal drying turntable 21; the drying air chamber 2 is communicated with a drying air inlet pipe 22, and the drying air inlet pipe 22 is externally connected to a constant-temperature air heater. In this example, a control valve is also provided on the drying air inlet pipe 22; in this embodiment, to ensure the stability of the operation of the centrifugal drying turntable 21, a first rolling bearing 25 is provided at its lower part and is rotatably connected to the device body 1. At the same time, a boss 21 is provided on the upper part of the centrifugal drying turntable 21, and the boss 21 is rotatably connected to the device body 1 through a second rolling bearing 20; above the centrifugal drying turntable 21, there are a turntable cover 6 and a feeding and air extraction pipe. The turntable cover 6 is rotatably fixed to the feeding and air extraction pipe through a rotating shaft 7; the drying and discharging are realized by controlling the lifting of the turntable cover 6. To improve the smoothness of the engagement during the lifting process, in this embodiment, a ring of convex rings 4 is provided at the top of the centrifugal drying turntable 21, and the lower outer side of the turntable cover 6 is also correspondingly set as a horizontal ring 5. The lower part of the feeding and air extraction pipe is arranged to be liftable, using a telescopic pipe body. Its lower section 8 and upper section 9 can relatively telescopically displace. The upper section 9 of the feeding and air extraction pipe is fixed to a support frame 15. In this embodiment, the support frame 15 is provided with a through hole. The lower part of the feeding and air extraction pipe passes through the through hole. At the same time, the lower section 8 of the feeding and air extraction pipe is sleeved outside the upper section 9 and can telescopically move up and down relative to the upper section 9. To improve the sealing performance and the smoothness of the telescoping, in this embodiment, a silica gel ring 10 is provided in the through hole; when driving the lower section 8 and the turntable cover 6, the solution of this embodiment is as follows: a rack 18 is provided on the outer side of the lower section 8 and is driven to lift by a lifting motor 17, and the lifting motor 17 is fixed to the support frame 15 through a motor bracket 16; the upper section 9 is communicated with an air extraction pipe 11, and the air extraction pipe 11 is externally connected to an air extraction pump; the top of the upper section 9 is communicated with a feeding funnel 12, and the feeding funnel 12 is fixed to the support frame 15 through a bracket; at the same time, an electric control material valve 14 is provided on the material conveying pipe. To improve the air extraction uniformity, in this embodiment, a number of air holes 23 are provided at the lower part of the lower section 8. In some embodiments, a retaining ring 19 can also be provided to prevent the material from being thrown too far.

[0024] When in use, the operating principle is as follows: Control the electric control material valve 14 to open to prompt the wood fiber to be dried to fall from the feeding suction pipe, and control the feeding amount within a certain range through time; after controlling the electric control material valve 14 to close, at this time, the turntable cover 6 covers the centrifugal drying turntable 21; start the centrifugal motor 24, the centrifugal drying turntable 21 rotates, and at the same time, the drying air inlet pipe 22 passes through constant temperature air below 80°C (such as 55°C, 60°C, 65°C, 70°C, etc.). The wood fiber to be dried rolls upward under the centrifugal force. At this time, during the rolling process, the constant temperature air is blown in from the drying air outlet hole 3 for alignment and drying. The air pump of the suction pipe 11 starts to pump air, and the moisture is extracted. Control the centrifugal motor 24 to rotate at a high speed for less than 10 s, and then change to a low speed rotation for less than 5 s to prompt the wood fiber thrown to the high place of the centrifugal drying turntable 21 to fall back to the bottom of the centrifugal drying turntable 21. During the falling process, the drying air outlet hole 3 continuously blows in air. Then the centrifugal motor 24 rotates at a high speed for less than 10 s again to prompt the wood fiber at the bottom to be thrown to a high place again. After repeating many times, the drying and discharging are completed. The discharging process is as follows: The centrifugal motor 24 runs at a low speed, and then the lifting motor 17 starts to prompt the turntable cover 6 to rise to a high position. After the lifting motor 17 stops, the centrifugal motor 24 rotates at a high speed to prompt the wood fiber to be centrifugally thrown out from the top of the centrifugal drying turntable 21 to below the retaining ring 19 to complete the discharging. Then when feeding, the centrifugal motor 24 changes to a low speed. At this time, the lifting motor 17 starts in the reverse direction to prompt the turntable cover 6 to descend and fit with the top of the centrifugal drying turntable 21. Then control the electric control material valve 14 to open for feeding, and repeat the above steps to complete the continuous drying of the material. Using this device can significantly reduce manual operations, especially in operations such as feeding and discharging, reduce labor costs. At the same time, this device uses a centrifugal method to prompt the wood fiber to tumble at a high speed in the centrifugal motor 24. At the same time, during the centrifugal tumbling process, constant temperature air is blown in through the air outlet hole 3 to dry the wood fiber. The wood fiber realizes continuous tumbling drying during the centrifugal outward throwing and falling process, which can significantly improve the drying uniformity of the internal and external moisture of the wood fiber, and can greatly shorten the drying time even at low temperatures, and the use effect is good.
