[0032] Working principle: the board for preparing wooden doors is placed on the conveying component 1, and the conveying component 1 is set as a conveyor belt. The conveying component 1 transmits the board to the bottom of the processing device 4, and then the rotating drive component 30 inside the driving device 3 is turned on. The rotating drive component 30 is turned on to drive the rotating shaft 31 to rotate. The rotation of the rotating shaft 31 drives the first gear plate 32 and the first movable wheel 33 to rotate. The rotation of the first gear plate 32 drives the two second gear plates 41 to rotate through the two first shaft rods 40. The rotation of the two second gear plates 41 drives the two meshing rods 410 to rotate. The rotation of the meshing rod 410 drives the bevel gear 42 to rotate. The rotation of the bevel gear 42 drives the connecting rod 420 to rotate. The connecting rod 420 rotates The second movable wheel 43 is driven to rotate by the second shaft 430, and the second movable wheel 43 rotates to drive the third movable wheel 44 to rotate through the second movable belt 431 and the third shaft 440, and the third movable wheel 44 rotates to drive the rotating arm 441 to rotate, and the rotating arm 441 rotates to drive the rotating column 442 to make a circular motion, and the circular motion of the rotating column 442 drives the return groove plate 45 to make a linear reciprocating motion, and the linear reciprocating motion of the return groove plate 45 drives the two movable plates 450 to make a linear reciprocating motion. When the movable plate 450 on the left side reciprocates in a linear motion, the movable plate 450 moves to drive the conveying plate 451, the spraying plate 46, the mounting frame 460, the smoothing roller 461 and the movable column 464 to move, and the movable column 4 The movement of the movable rod 465 drives the movable rod 465 to make a linear reciprocating motion. The movement of the movable rod 465 drives the piston plate 466 to make a linear reciprocating motion in the storage bin 47. In the initial state, the spray plate 46 is at the right end position. Putty is stored in the storage bin 47 and the storage bin 48. When the piston plate 466 moves to the left, the air pressure inside the storage bin 47 increases, and the putty inside the storage bin 47 is pressed into the spray plate 46 through the delivery pipe 470. At this time, the spray plate 46 makes a linear reciprocating motion from left to right to lay putty on the surface of the plate, and the putty is used to fill the pinholes on the surface of the plate due to cutting processing, so as to avoid the pinholes on the surface of the plate affecting the subsequent painting quality. The second one-way valve 473 is used to prevent the storage The putty in the bin 47 flows back into the extraction pipe 472. When the spray plate 46 is reset, the piston plate 466 moves to the right. At this time, the air pressure in the storage bin 47 changes and the putty in the storage bin 48 is pumped into the storage bin 47 through the extraction pipe 472 for replenishment. The first one-way valve 471 is used to prevent the putty at the transport pipe from flowing back, and the smoothing roller 461 at the rear end of the spray plate 46 moves with the movement of the spray plate 46 to flatten the putty sprayed on the surface of the board by the spray plate 46, so as to avoid the uneven surface of the board after the putty is sprayed on the board. The device can fill the pinholes on the surface of the wooden door board, improve the pretreatment effect of the device and the painting quality of the board, and facilitate the use of users. When the movable plate 450 on the right side moves linearly back and forth, the movable plate 450 moves to drive the fixed plate 462 to move, and the fixed plate 462 moves to drive the polishing plate 463 to move, and the polishing plate 463 moves to compact the putty on the surface of the plate, so as to avoid uneven distribution of putty sprayed on the surface of the plate, and it is difficult to fill the pinholes with less putty. At the same time, the polishing plate 463 moves to polish the burrs on the surface of the plate to ensure the flatness of the surface of the plate, so as to avoid the situation that the surface of the wooden door plate is uneven during subsequent painting, which reduces the quality of the painting, thereby improving the pretreatment effect of the device and the painting quality of the plate, and facilitating user use; When the first movable wheel 33 rotates, the fourth movable wheel 52 is driven to rotate through the first movable belt 34. The fourth movable wheel 52 rotates and drives the screw 53 to rotate through the fourth shaft rod 51. The rotation of the screw 53 drives the through rod 54 to extend from the through groove 50 and move downward. The movement of the through rod 54 drives the hot pressing component 55 to move. After the wooden door board is processed, the conveying component 1 moves it to the drying device 5. At this time, the hot pressing component 55 is at the top of the board. As the conveying component 1 continues to move, the board is continuously moved at the bottom of the hot pressing component 55. The hot pressing component 55 increases the temperature of the board surface by applying pressure to the board and increasing the heating area of ​​the board, thereby quickly drying the putty at the pinholes of the board to avoid affecting the subsequent painting effect. At the same time, the surface of the board is heated to avoid the high water content of the painted surface of the board, which causes the paint surface to enter the board and mix with water during subsequent painting, thereby causing the paint surface of the wooden door to turn white, thereby improving the pretreatment quality and painting effect of the device, and facilitating user use.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
