The fixed plate is also provided with a guide rod. One end of the guide rod is connected to the fixed plate, and the end of the guide rod away from the fixed plate extends outward through the uniformizing bracket. The guide rod is used to limit the vertical movement distance of the fixed plate. The brush roller drive assembly is installed on the lower surface of the moving block. The moving block is installed on the brush roller drive mechanism and can move along the length direction of the brush roller drive mechanism to make the brush roller mechanism abut against the inner side of the wooden board.

6. The paint drying device for wooden door production according to claim 5, characterized in that, The brush roller mechanism includes a brush roller bracket, a mounting shaft, and a brush roller. The mounting shaft is mounted on the brush roller bracket, and the brush roller is sleeved on the mounting shaft and can rotate around the axis of the mounting shaft. The end of the brush roller bracket away from the brush roller is connected to a moving block through a connecting shaft. When the moving block moves along the brush roller drive mechanism, it can drive the brush roller bracket to move.

7. A paint drying device for wooden door production according to claim 6, characterized in that, The drying assembly is located on the upper surface of the frame and includes a drying support. A drying chamber is provided inside the drying support. A ventilation grille is provided at one end of the drying chamber, and the end with the ventilation grille faces the wooden board. An electric heating wire is provided inside the drying chamber and is electrically connected to an external power source.

8. The method of using the paint drying device for wooden door production according to claim 7, characterized in that, Includes the following steps: S1: Wooden Board Installation: Place the fixing frame on the outside of the wooden board, then place the fixing frame and the wooden board into the fixing component through the fixing groove; S2: Wooden Board Conveying: Start the conveyor motor, drive the drive wheel, driven wheel, first transmission belt, transmission shaft, first drive wheel, second drive wheel, and second transmission belt, thereby driving the clamping drive mechanism to move, thus moving the wooden board set on the clamping drive mechanism, passing through the painting assembly, uniform assembly, and drying assembly in sequence; S3: Paint Spraying: When the wooden board moves to the painting assembly, the conveying assembly stops, the longitudinal drive mechanism is started to drive the longitudinal platform to move the transverse drive mechanism towards the wooden board, then the transverse drive mechanism is started to move the painting mechanism to one end of the wooden board, then the transverse drive mechanism drives the painting mechanism to move, and at the same time the painting mechanism is started to spray paint onto the wooden board. After the painting is completed, the conveying assembly starts; S4: Oil S5: Paint Spreading Evenly: When the wood board moves to the evenness component, the conveying component stops, and the brush roller drive mechanism is activated. The brush roller moves towards the wood board until it contacts the side of the board. Then, the lifting cylinder is activated to drive the brush roller downward, spreading the paint evenly on the surface of the wood board. The conveying component is then activated again. S6: Paint Surface Drying: When the wood board moves to the drying component, the conveying component stops, the heating wire is energized, and heat flows out through the ventilation grille to dry the paint on the wood board. A thin paint film forms on the surface of the wood board, setting the paint. After the paint dries, the conveying component is activated again. S7: Remove the wood board and the fixing frame. Place the unprocessed end of the wood board inward on the fixing component. Repeat the above process until both sides of the wood board are processed. S8: Remove the processed wood board and air dry it in a cool place until the paint layer is dry inside.
