[0015] Step 1: When the gypsum board needs to be dried, first manually push the sealing plate away from the dehumidification equipment to release the seal of the drying box;

[0016] Step 2: After the seal of the drying box is released, manually pull the L-shaped plate upward to remove the obstruction to the front side of the placement frame. After the obstruction to the front side of the placement frame is removed, place the gypsum board to be dried into the placement frame;

[0017] Step 3: After the gypsum board is placed in the placement frame, the sealing plate is manually pushed toward the dehumidifier to restore the seal of the dehumidifier. At the same time, the servo motor drives the rotating rod to rotate, the rotating rod drives the sliding rod to rotate, the sliding rod drives the placement frame to rotate, and the placement frame drives the gypsum board inside the placement frame to rotate together;

[0018] Step 4: When the placement frame drives the gypsum board inside the placement frame to rotate together, the drying equipment and the dehumidification equipment are started to dry the gypsum board inside the placement frame.

[0019] The present invention provides a double-sided drying device for processing gypsum board, which has the following beneficial effects:

[0020] (1) The invention drives the sliding rod to rotate by rotating the rotating rod, which drives the placing frame to rotate by rotating the sliding rod, which drives the gypsum board inside the placing frame to rotate together. By rotating the gypsum board, water droplets attached to the surface of the gypsum board can be thrown off by centrifugal force, thereby accelerating the drying speed. The placing ring moves and resets to drive the sliding rod to move and reset, which drives the placing frame to move and reset. The placing frame moves back and forth horizontally to drive the gypsum board inside the placing frame to move together. The movement of the gypsum board can enhance the air flow inside the drying box, improve the moisture discharge efficiency, and further accelerate the drying process of the gypsum board.

[0021] (2) The invention moves the load-bearing frame downward to contact the filter plate and push the solid particles on the surface of the filter plate. By setting a dehumidification device, the humidity in the airflow can be effectively reduced, the evaporation of water can be accelerated, and the overall drying speed can be improved. The solid particles on the surface of the filter plate can be pushed and removed, so that the hot and humid airflow can pass through the filter plate more smoothly, reducing the resistance of air flow, thereby improving the dehumidification efficiency. The vibration of the load-bearing plate drives the load-bearing rod and the load-bearing frame to vibrate, and the vibration of the load-bearing frame drives the filter plate to resonate together. The vibration can effectively shake off the solid particles attached to the surface of the filter plate, keep the filter surface clean, and then increase the passing rate of the hot and humid airflow, thereby further improving the dehumidification efficiency.

[0022] (3) In the present invention, after the limit plate contacts the load-bearing plate, the limit plate moves downward under the elastic force of the No. 4 spring. The limit plate moves downward to break away from the contact with the protective groove and releases the limit on the driving button. The driving button can be pressed only after the limit on the driving button is released. When the driving button is pressed, the drying equipment can be driven to perform the drying operation. The drying equipment can be started only after it is detected that the drying box is completely sealed, which can ensure that the drying box is well sealed, thereby reducing the loss of heat and moisture, making the drying process more efficient and improving the overall drying speed.

[0038] Step 2: After the seal of the drying box 1 is released, the L-shaped plate 12 is manually pulled upward to remove the shielding of the front side of the placement frame 10. After the shielding of the front side of the placement frame 10 is released, the gypsum board to be dried is placed inside the placement frame 10;

[0039] Step 3: After the gypsum board is placed in the placement frame 10, the sealing plate 3 is manually pushed to move toward the dehumidification device 5 to restore the seal of the dehumidification device 5. At the same time, the servo motor 7 drives the rotating rod 8 to rotate, the rotating rod 8 rotates to drive the sliding rod 9 to rotate, the sliding rod 9 rotates to drive the placement frame 10 to rotate, and the placement frame 10 rotates to drive the gypsum board inside the placement frame 10 to rotate together;

After the gypsum board to be dried is placed inside the placement frame 10, the L-shaped plate 12 is loosened so that the L-shaped plate 12 moves downward under the elastic force of the second spring to restore the shielding of the placement frame 10. After the gypsum board is placed inside the placement frame 10, the sealing plate 3 is manually pushed toward the direction close to the dehumidification device 5 to restore the seal of the dehumidification device 5. At the same time, the servo motor 7 drives the rotating rod 8 to rotate, the rotating rod 8 rotates to drive the sliding rod 9 to rotate, the sliding rod 9 rotates to drive the placement frame 10 to rotate, and the placement frame 10 rotates to drive the gypsum board inside the placement frame 10 to rotate together.

At the same time, the load-bearing frame 163 moves downward to contact the filter plate 168 and pushes the solid particles on the surface of the filter plate 168. At the same time, the load-bearing rod 162 moves downward with The dynamic load-bearing block 165 moves downward, and the load-bearing block 165 moves downward and hits the load-bearing plate 161 to generate vibration. The vibration of the load-bearing plate 161 drives the load-bearing rod 162 and the load-bearing frame 163 to vibrate, and the vibration of the load-bearing frame 163 drives the filter plate 168 to resonate together. The placement ring 15 moves and resets in the direction away from the dehumidification equipment 5 under the elastic force of the No. 1 spring.

The load-bearing rod 162 moves and resets upward, driving the load-bearing frame 163 to move and reset.

[0048] The sealing plate 3 is manually pushed to move toward the dehumidification device 5 so that the protection plate 176 limits the driving button 177.

The support rod 172 is squeezed by the convex plate 166 and moves away from the load-bearing plate 161. The support rod 172 moves away from the load-bearing plate 161 to pull the No. 3 spring. The No. 3 spring is squeezed by the support rod 172. The pulling produces deformation and accumulates force, and the support rod 172 moves away from the load-bearing plate 161 so that the support groove contacts the limit plate 175. After the limit plate 175 contacts the load-bearing plate 161, the limit plate 175 moves downward under the elastic force of the No. 4 spring, and the limit plate 175 moves downward to break away from the contact with the protective groove and release the limit on the drive button 177.
