[0059] Specifically, a hot air pipe 421 is fixedly installed in the middle of the dehumidification air supply hood 42, and one end of the hot air pipe 421 extends to the top of the air guide assembly 23, the hot air pipe 421 is connected to the first air guide hood 231, and a moisture exhaust pipe 431 is fixedly installed in the middle of the dehumidification exhaust hood 43, and one end of the moisture exhaust pipe 431 extends to the outside of the drying chamber 1. The hot air with water vapor can be discharged to the outside of the device through the moisture exhaust pipe 431 to avoid affecting the plate.

[0060] In summary, in the actual application of the device, the material rack 3 can support the plate, and the material rack 3 can be pushed into the processing chamber 2, and together with the processing chamber 2, form a drying space for plate processing. In the process of drying the plate, the circulating fan 442 can draw air from the outside through the air supply pipe 444, and transport the air to the heating hood 22 through the air intake pipe 443. The air is heated by the electric heating wire 24 in the heating hood 22 to form hot air, and the hot air passes through the gaps between multiple plates to achieve the drying process of the plate.

[0061] At the same time, the water vapor volatilized during the drying process of the plate follows the hot air through the air inlet hood 452 and the moisture inlet pipe 451 and is transported to the moisture absorption air supply hood 45, and then the hot air with water vapor passes through the dehumidification plate 412, and the dehumidification plate 412 adsorbs the water vapor in the hot air. The hot air after adsorption passes through the moisture absorption exhaust hood 44 and the return air pipe 441 and enters the circulation fan 442 again, and the circulation fan 442 transports the hot air to the heating hood 22 again to realize the recycling of the hot air.

[0062] The dehumidification plate 412 can rotate along with the rotating shaft 411 during the process of continuously absorbing water vapor, so that the dehumidification plate 412 with water vapor rotates to the inside of the dehumidification air supply hood 42. At this time, the hot air in the air guide component 23 can directly enter the dehumidification plate 412 through the hot air pipe 421 and the dehumidification air supply hood 42. At this time, the temperature of the hot air that has not exchanged heat with the plate is relatively high. The high-temperature hot air can bring out the water vapor in the dehumidification plate 412 during the process of passing through the dehumidification plate 412, so as to achieve the effect of regenerating the dehumidification plate 412, and the hot air with water vapor can be discharged to the outside of the device through the moisture exhaust pipe 431 to avoid affecting the plate.

[0063] During the drying process, since the undried board has a high humidity and the air flow after passing through the board has a high moisture content, the circulation speed of the drying air flow should be accelerated to quickly remove the moisture on the surface of the board and achieve rapid drying of the board. Specifically, the telescopic rod 346 is controlled to extend, and the support arm 34 will move downward at this time, so that the multiple support frames 32 are tilted toward the side close to the air guide component 23, that is, the side of the board close to the air guide component 23 is lower and the side away from the air guide component 23 is higher. Moreover, since the limit rod 343 moves downward with the movable end of the telescopic rod 346, the transmission rod 52 will move downward under the pulling force of the reset member 56, so that the multiple first air guide plates 233 are in an inclined state and overlap at the opening of the corresponding second air outlet 235. Fig.13 and Fig.14 As shown, at this time, the airflow in the first air guide cover 231 will be blown out from the second air outlet 235 along the first air guide plate 233 in an oblique upward direction through the first air outlet 232. At this time, the dry gas keeps blowing on the surface of the plate in an oblique upward direction, and cooperates with the suction force at the air inlet cover 452 to quickly blow the moisture on the surface of the plate upward, thereby achieving a preliminary rapid drying process for the plate;

[0064] After the plate is quickly dried, the humidity of the plate is relatively low, and the moisture content carried in the airflow after the plate is relatively low. The airflow still has good drying ability, so there is no need to dry it at a high circulation speed. Moreover, what the plate needs more at this time is the dry gas to slowly dry it, so the drying time of the unit airflow should be extended to achieve slow drying of the plate. Specifically, the telescopic rod 346 is controlled to be shortened, and the support arm 34 will move upward at this time, so that the multiple support frames 32 are tilted toward the side away from the air guide component 23, that is, the side of the plate close to the air guide component 23 is higher and away from the air guide component One side of the component 23 is lower, and as the limiting rod 343 moves upward following the movable end of the telescopic rod 346, the connecting frame 58 will pull the transmission rod 52 upward through the connecting block 57, and the transmission rod 52 cooperates with the tooth segment 55 and the transmission gear 59 to make the multiple first air guide plates 233 rotate synchronously and gradually block the first air outlet 232. When the limiting rod 343 rises to the highest point, the first air guide plate 233 completely blocks the first air outlet 232. Since the multiple first air outlets 232 are all blocked, the air pressure in the first air guide cover 231 gradually increases, and the cover plate 239 will rotate upward to keep the air guide window 238 in an open state. Fig.15 and Fig.16 As shown, at this time, the airflow enters the second air guide cover 234 and is blown out from the second air outlet 235 along the second air guide plate 236 at an inclined downward angle. After flowing through the surface of the plate, the airflow first moves downward to the bottom of the sealing cover 21, and then slowly floats upward, thereby achieving the effect of first blowing on the surface of the plate and then slowly drying the entire plate, which significantly improves the drying effect of the plate; at the same time, since the dry gas does not need to circulate quickly, the circulating fan 442 does not need to continuously maintain a high-speed circulation power, which reduces the use pressure of the circulating fan 442 and reduces energy consumption losses.

[0065] The present invention also provides a drying method for a drying device for plate production, comprising the following steps:

[0066] Step 1: placing the plates to be dried on the multiple support frames 32 inside the material rack 3, and then adjusting the angles of the support frames 32 so that the multiple plates are in an inclined state;

[0067] The angle of the support frame 32 can be fixed by the connecting arm 341, the movable arm 342, the limiting rod 343 and the limiting seat 344. After the support frame 32 is adjusted to the inclined state, the hot air can pass through the gaps between the plates from the oblique downward direction to the oblique upward direction to improve the circulation effect of the hot air.

[0068] Step 2: feeding, pushing the material rack 3 loaded with the plate into the drying chamber 1, and inserting the material rack 3 into the processing chamber 2, and the material rack 3 can enter and exit through the movable door 11 on the drying chamber 1;

[0069] Step 3, drying, air is injected into the heating cover 22 through the circulating fan 442, and the air passes through the heating cover 22 and passes between the multiple plates to achieve drying of the plates. The water vapor generated during the drying process is absorbed by the dehumidification wheel 4 to achieve continuous processing of the plates;

[0070] Step 4: unloading. After the board is dried, the rack 3 is pushed out and the board is removed to complete the drying process of the board.
