The specific implementation process is as follows: the conveyor belt 29 and the motor 30 are activated, fixing the boards one against the other on the conveyor belt 29, the boards following the conveyor belt 29 from left to right, since both sides of the rubber belt 54 in the length direction are inclined, when the wooden board is brought into contact with the rubber belt 54, an upward pushing force is applied to the driving shaft 24 along the inclined surfaces, and in turn causes the drive shaft 24 to exert an upward force on the sleeve, via the first, second and third locating collars 19, causing the sleeve to slide upward, so that the drive shaft 24 is moved upwards as a whole, when the board reaches under the first grinding pulley 15, the first grinding belt wheel 15 is pressed by gravity against the surface of the board, while, due to the rotation of the drive shaft 24, the grinding belt 16 is constantly moving, thereby, burrs and irregularities on the surface of the wooden board are polished, and powder impurities which are polished accumulate in the depressions of the polishing layer 55 and are pushed away to the surface of the wooden board with the movement of the polishing layer 55.
Then, the sleeves connected with the side walls of the first positioning ring 17 and the second positioning ring 18 move upwards due to the upward movement of the driving shaft 24, so that the first pushing rod 33 and the second pushing rod move upwards along with the sleeves, the first pushing rod 33 and the second pushing rod push the first control board 47 and the second control board towards the direction close to the first paint box 31 and the second paint box 32 respectively through the wedge surfaces at the ends of the first control board 47 and the second control board, so that the control holes 48 and the paint holes 49 on the first control board 47 and the second control board are aligned, so that the paint holes 49 are communicated with the paint boxes, and simultaneously, due to the upward movement of the driving shaft 24, the driving shaft 24 drives the positioning shaft 53 to move upwards, so that the second bevel gear 26 and the driving sprocket 27 move upwards, the driving sprocket 27 drives the driven sprocket 34 to move upwards while driving the driven sprocket 34 to rotate through the roller chain 28, the driven sprocket 34 located in the center of the five driven sprockets 34 drives the paint spraying driving rotating shaft 13 to move upwards, the telescopic rotating shafts 37 at the upper ends of the other driven sprockets 34 are shortened, so that the wedge 44 in the blind hole 45 is pressed into the blind hole 45 under the limit of the lower end surface of the driving liquid conveying belt wheel 12, when the blind hole 45 is aligned with the clamping groove 43, the wedge 44 is ejected out of the blind hole 45 and inserted into the clamping groove 43 under the action of the second pressure spring 46, so that the paint spraying driving rotating shaft 13 drives the driving liquid conveying belt wheel 12 to rotate, the driving liquid conveying belt wheel 12 drives the driven liquid conveying belt wheel 8 to rotate through the belt 7, the driven liquid conveying belt wheel 8 drives the lead screw 9 to rotate, the piston plate 10 overcomes the elasticity of the reset pressure spring 11 to move downwards under the rotation of the lead screw 9, and simultaneously, the paint below the piston plate 10 is extruded by the piston plate 10 and flows into the first paint spraying box, since the control holes 48 on the first control plate 47 and the second control plate are aligned with the paint spraying holes 49 at this time, paint is sprayed from the paint spraying holes 49 toward the wood boards, thereby realizing the first paint spraying of the wood boards;
when the wood board passes through the first paint spraying box 31, the wood board reaches the second grinding belt wheel 21, a layer of paint is coated on the wood board at the moment, but paint droplets on the paint surface are not uniformly distributed, so that the problem of uneven paint surface exists, meanwhile, the paint layer has thickness, so that the diameter of the second grinding belt wheel 21 is smaller than that of the first grinding belt wheel 15, the grinding amount of the second grinding belt wheel 21 to the wood board is smaller than that of the first grinding belt wheel 15, when the wood board passes through the second belt wheel, the second grinding belt wheel 21 drives the grinding belt 16 to grind the paint on the wood board surface, and the ground paint powder is also driven by the depressions on the grinding belt 16 to leave the wood board surface and then blown off by the air flow in the air guide pipe 23;
after the wood board reaches the second polishing belt wheel 21, the wood board reaches the second paint spraying box 32, the second layer of paint is coated on the wood board, the first layer of paint is used for filling up the concave and convex parts which are difficult to remove on the surface of the wood board, the brightness of the wood board is improved through the second layer of paint, and meanwhile, the paint layer is thickened, so that the moisture-proof and insect-proof effects of the paint layer on the wood board are improved;
after the wood board passes through the second paint spraying box 32, the wood board reaches the driven sprocket 34, the driven sprocket 34 is driven to rotate by the driving shaft 24 through the first bevel gear 25, the second bevel gear 26 and the driving sprocket 27, so that the driven sprocket 34 drives the second rotating shaft 35 and the blades 36 to rotate, and air flow blowing to the surface of the wood board is generated through the rotation of the blades 36, so that paint on the surface of the wood board is dried quickly;
after the wood board passes through the driven chain wheel 34, the wood board reaches the polishing belt wheel 22, and the diameter of the polishing belt wheel 22 is smaller than that of the second polishing belt wheel 21, so that the polishing amount of the polishing belt wheel 22 to the wood board is further reduced, and only surface paint is polished to improve the paint brightness;
after all the boards have passed completely through the drive shaft 24, the painting of the boards is completed. At this time, the driving shaft 24 is no longer subjected to upward supporting force from the wood board, so that the driving shaft 24 falls under the action of its own gravity, so that the driving shaft 24 pulls the bump to move downward through the annular clamping groove 52, and further, the positioning shaft 53 falls along with the falling of the driving shaft 24, so that the paint spraying driving rotating shaft 13 is subjected to downward force, and further, the wedge 44 slides out from the clamping groove 43, so that the paint spraying driving rotating shaft 13 is separated from the driving liquid conveying belt wheel 12, after the paint spraying driving rotating shaft 13 is separated from the driving liquid conveying belt wheel 12, the piston plate 10 is subjected to upward elastic force under the action of the return pressure spring 11, and at this time, the driving liquid conveying belt wheel 12 is no longer subjected to the limiting action of the paint spraying driving rotating shaft 13, so that the driven liquid conveying belt wheel 8 and the lead screw 9 are not limited by the driving liquid conveying belt wheel 12, and therefore, the screw rod 9 further drives the driven infusion belt wheel 8 and the driving infusion belt wheel 12 to idle, when the elastic potential energy of the reset spring is completely released, the piston plate 10 resets, and the driven infusion belt wheel 8 and the driving infusion belt wheel 12 stop idle running.
The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
