In order to provide the method of use and the advantages of the invention, the steps of the integrated painting device for the surface of the door leaf when in use are described in detail as follows:

the method comprises the following steps: as shown in fig. 1 and fig. 2, wooden doors to be painted are stacked in the feeding box 6 in sequence, the controller controls the motor to work, the motor drives the belt wheel to rotate, so that the belt 5 runs clockwise, the belt 5 drives the push block 32 to run clockwise along with the belt 5, when the push block 32 runs from left to right, as shown in fig. 8, the push block 32 pushes the wooden door at the lowest end of the feeding box 6 to the support table 27 at the left end of the second conveying frame 21, the shift lever 8 is located at the second touch switch 9 in the process, the piston rods of the first cylinder 18 and the second cylinder 24 are both in an extending state, namely the first lifting plate 19 and the second lifting plate 25 are close to each other, the cleaning box 28, the painting box 29 and the drying box 30 are in an involuting state, and the press plate 26 presses the press rod 33, so that the press rod 33 moves downwards and applies a force to the corresponding push rod 35 through the connecting rod 36, and the force, and the second spring 34 is stretched, so that the second spring 34 obtains a restoring force, the ejector rods 35 in the two clamping mechanisms at the left end of the second conveying frame 21 are away from each other, so that the wooden door can move to the supporting table 27 under the action of the push block 32, so that the subsequent ejector rods 35 can clamp and fix the wooden door subjected to paint spraying treatment, and the ejector rods 35 in the two clamping mechanisms at the left end of the second conveying frame 21 are away from each other, so that the wooden door subjected to paint spraying treatment can be conveniently loosened, and the wooden door subjected to paint spraying treatment can be conveniently conveyed to the next process under the action of the conveying belt 31;

step two: as the belt 5 drives the push plate 32 to move, as shown in fig. 2 and fig. 3, the push plate 32 moves from right to left, in the process, the push plate 32 is in buckling contact with the upper end of the shift lever 8, and the left movement of the push plate 32 synchronously drives the shift lever 8 to move left, the left movement of the shift lever 8 synchronously drives the rack 15 to move left, so that the rack 15 stretches the spring one 16, so that the spring one 16 obtains a restoring force, the rack 15 drives the outer ring of the ratchet 13 to rotate clockwise in the process of moving the rack 15 to move left, at the moment, the outer ring of the ratchet 13 cannot drive the inner ring of the ratchet 13 to rotate through the pawl, and cannot drive the gear two 14 to rotate through the rotating shaft 11 and the gear one 12, so as to keep the chain wheel 23 and the chain 22 stationary, so as to ensure that the wood door remains stationary in the air injection process, after the push block 32 is about to be separated from the upper, the first touch switch 7 receives a touch signal and transmits the touch signal to the controller, the controller controls the first cylinder 18 and the second cylinder 24 to contract the piston rods of the first cylinder and the second cylinder, so that the first lifting plate 19 and the second lifting plate 25 are far away from each other, and simultaneously the cleaning box 28, the paint spraying box 29 and the drying box 30 are in a separated state, so that the chain 22 drives the wooden door to move rightwards through the clamping mechanism, after the push block 32 is separated from the shift lever 8, no force is exerted on the shift lever 8, so that the rack 15 moves rightwards under the action of the restoring force of the first spring 16, the right movement of the rack 15 drives the outer ring of the ratchet 13 to rotate anticlockwise, at the moment, the outer ring of the ratchet 13 can drive the inner ring of the ratchet 13 to synchronously rotate anticlockwise through the pawl, so that the inner ring of the ratchet 13 can drive the first gear 12 to rotate anticlockwise through the rotating shaft 11, and, therefore, the second gear 14 drives the chain wheel 23 to rotate clockwise through the shaft lever 38, and further drives the chain 22 to move clockwise through the chain wheel 23, due to the upward movement and return of the lifting plate 25, the pressing plate 26 is far away from the pressing rod 33, and further under the restoring force of the second spring 34, the two ejector rods 35 in the clamping mechanisms corresponding to the left end and the right end of the second conveying frame 21 are close to each other, and meanwhile, the ejector rods 35 exert an upward force through the pressing rods 33 corresponding to the connecting rods 36, so that the pressing rod 33 is returned to clamp and fix the wooden door to be processed on the supporting table 27, so that when the chain 22 moves clockwise, the wooden door to be processed on the supporting table 27 is moved to the cleaning box 28, the clockwise movement of the chain 22 simultaneously moves the wooden door at the cleaning box 28 to the drying box 29, the wooden door at the drying box 29 to the drying box 30 to the conveyor belt 31, the wooden door can be sequentially moved, so that the wooden door can be sequentially cleaned, painted and dried without being transported for many times, the labor intensity is reduced, and the production efficiency is improved; it should be noted that the present application is prior art to the art of cleaning, painting and drying, and the present application is not limited to the particular method of cleaning, painting and drying.

Step three: when the shift lever 8 moves to the second touch switch 9 to the right and is fastened with the second touch switch 9, the second touch switch 9 receives the touch signal of the shift lever 8, so that the touch signal is transmitted to the controller, the controller controls the first cylinder 18 and the second cylinder 24 to extend again to enable the first lifting plate 19 and the second lifting plate 25 to approach each other, further the cleaning box 28, the paint spraying box 29 and the drying box 30 are in a closing state, thereby cleaning, painting and drying the wooden door at the corresponding position, and in order to synchronously perform, the production efficiency is improved, the downward movement of the second lifting plate 25 enables the pressing plate 26 to press down the corresponding pressing rod 33 again, so that the clamping mechanism corresponding to the conveyor belt 31 loosens the wooden door after painting treatment, the clamping mechanism at the supporting table 27 is in a loosening state, so that the motor drives the pushing plate 32 to push the wooden door at the lowest end of the feeding box 6 to the supporting table 27 through the belt wheel and the belt 5, the realization is to the autoloading of timber, labour saving and time saving, so circulate, realize the continuity of timber and spray paint the processing, improved work efficiency greatly.
