Description

Technical Field

[0001] The invention belongs to the technical field of furniture spray painting, in particular to a furniture processing spray painting device. Background Art

[0002] As the demand for furniture grows, simple automatic painting equipment is gradually entering factories, such as reciprocating paint sprayers, which rely on precise program control and mechanical transmission systems to operate. The operator first properly fixes the workpiece to be painted in the painting work area. After starting, the spray gun will reciprocate back and forth along the preset track; at the same time, the spray gun sprays paint mist, which evenly adheres to the surface of the workpiece to complete the painting process. This regular reciprocating motion can ensure that all parts of a large area of ​​workpieces have a uniform and consistent painting effect; However, when using a reciprocating paint sprayer to spray furniture panels of different widths, it is necessary to manually adjust the reciprocating stroke of the spray gun according to the width of the furniture panels.

[0010] The beneficial effects of the present invention are as follows: 1. The furniture processing and painting equipment described in the present invention, when painting furniture panels of different widths, the furniture panels will push the two guide plates away from each other, and the guide plates will drive the two baffles to move away from each other along the first screw. Due to the different widths of the furniture panels, the distances by which the two guide plates are pushed are different. When the two baffles move away from each other, the slide plate on the drive box is pushed to change the moving direction of the drive box, so that the drive box can move back and forth between the two baffles. Since the distance between the two guide plates and the two baffles is determined according to the width of the furniture panel, the distance between the guide plates and the baffles can be automatically adjusted according to the width of the panel, thereby automatically adjusting the reciprocating stroke of the drive box and the nozzle, without the need to manually adjust the reciprocating stroke of the nozzle, and at the same time, the use range of the reciprocating paint sprayer can be increased.

[0011] 2. The furniture processing and painting equipment described in the present invention, by setting a limit plate, when it is necessary to spray paint on plates of different thicknesses, the moving plate will push the limit plate up, and the upward moving limit plate will drive the U-shaped plate, the mounting plate, the drive box and the nozzle to move upward as a whole through multiple support rods. In this process, it can be ensured that when spraying paint on plates of different thicknesses, the distance from the top end face of the plate to the nozzle is the same, thereby avoiding differences in the paint liquid sprayed on the furniture plate due to changes in the distance between the nozzle and the furniture plate.

[0012] 3. The furniture processing and painting equipment described in the present invention can block the diffusion of the floating paint liquid due to the existence of the rotating belt during the process of painting the plate, and avoid excessive paint liquid from diffusing into the external environment. At the same time, the third motor can be controlled to rotate, and the rotating third motor can drive the two rotating belts to rotate in the first slot and the second slot respectively through the rotating shaft. Since the absorbent cotton layer is fixedly connected to the rotating belt, the diffused paint liquid can be absorbed. When the rotating belt that absorbs the paint liquid rotates into the collecting box, the squeezing rod will squeeze the absorbent cotton layer passing by, so that the paint liquid absorbed by the absorbent cotton layer can be squeezed into the collecting box, thereby avoiding the absorbent cotton layer from absorbing the paint liquid for a long time and becoming saturated, thereby causing the paint liquid to drip.

In the initial state, the second screw 42 on the right side is engaged with the first screw 23, and there is a distance between the second screw 42 on the left side and the first screw 23. The right end surface of the sliding bin 4 is fixedly connected to a Z-shaped rod 44 via two connecting rods; the Z-shaped rod comprises a near rod 441, an oblique rod 442 and a far rod 443; A U-shaped frame 45 is provided below the Z-shaped rod 44, and the remote rod 443 slides in the U-shaped frame 45 in the initial state; a slide plate 46 is fixedly connected to the U-shaped frame 45, and the slide plate 46 slides in the drive box 24; the slide plate 46 is located on one side of the back of the first motor 43 and is extended from the drive box 24; the slide plate 46 is located on one side of the back of the second screw rod 42 and is flush with the outer surface of the drive box 24; Specifically, when painting furniture, first place the furniture plate to be painted at the entrance position of the reciprocating paint sprayer, and then control the multiple rollers 12 to rotate. The rotating rollers 12 will drive the furniture plate to move. The moving furniture plate will first contact the curved parts on the two guide plates 3 and move along the first rollers 31. During the movement of the furniture plate, it will gradually squeeze between the two guide plates 3, and at the same time push the two guide plates 3 to move to the opposite side. At the same time, the guide plate 3 will drive the second guide rod 32 to move. The moving second guide rod 32 will squeeze the spring between the guide plate 3 and the chassis 13. During the movement of the guide plate 3, the bottom plate 33 will be driven to move. At the same time, the bottom plate 33 will drive the telescopic cylinder 34 and the baffle 35 to move. Since the baffle 35 slides on the first screw 23, the baffle 35 will move along the first screw 23. When the furniture plate moves to the side end face where the two guide plates 3 are parallel to each other, the two guide plates 3 are no longer away from each other, and then the furniture plate will move below the spray head 25. More specifically, the two first motors 43 are controlled to rotate, wherein one of the first motors 43 drives the second screw rod 42 on the left to rotate counterclockwise, and the other first motor 43 drives the second screw rod 42 on the right to rotate clockwise. Since the second screw rod 42 on the right is meshed with the first screw rod 23 in the initial state, the second screw rod 42 on the right that rotates moves along the first screw rod 23. Since the second screw rod 42 rotates in the slide bin 4, and the slide bin 4 is located in the drive box 24, the second screw rod 42 that moves along the first screw rod 23 drives the slide bin 4, the drive box 24, and the slide plate 46 on the drive box 24 to move toward the slide plate 46. The extended side moves, and when the moving slide plate 46 contacts the baffle plate 35 on the extended side of the slide plate 46, the extended slide plate 46 will be gradually pushed into the drive box 24 under the obstruction of the baffle plate 35, and at the same time, the other side of the slide plate 46 will gradually extend from the other side of the drive box 24. In the process of the slide plate 46 being gradually pushed into the drive box 24, the slide plate 46 will drive the U-shaped frame 45 to move along the Z-shaped rod 44. When the extended slide plate 46 is completely pushed into the drive box 24, the other side of the slide plate 46 no longer extends from the drive box 24, and at the same time, the U-shaped frame 45 moves from the far rod 443 position to the near rod 441 position; Furthermore, when the U-shaped frame 45 moves from the far rod 443 position to the near rod 441 position, the moving U-shaped frame 45 will pull the slide bin 4 to move rightward as a whole. In the process of the slide bin 4 moving rightward, the two second screw rods 42 will be driven to move rightward. At the same time, the oblong groove 41 will move along the first screw rod 23, and the second screw rod 42 on the right side will gradually disengage from the first screw rod 23. When the second screw rod 42 on the right side is completely disengaged from the first screw rod 23, the second screw rod 42 on the left side will mesh with the first screw rod 23. 2, so the second screw rod 42 rotating on the left side will move in the opposite direction along the first screw rod 23, and at the same time will drive the slide box 4, the drive box 24 and the slide plate 46 to move in the opposite direction. When the slide plate 46 on the drive box 24 moving in the opposite direction contacts the baffle plate 35 on the other side, the slide plate 46 will drive the U-shaped frame 45 to move from the near rod 441 position to the far rod 443 position, thereby pushing the slide box 4 to move to the left as a whole and restore the initial state. In this process, the drive box 24 can move back and forth between the two baffle plates 35; Furthermore, when the furniture board moves to the bottom of the spray head 25, the spray head 25 moving back and forth will spray paint on the furniture board passing by, and when the spraying of the furniture board is finished, it will gradually move out of the reciprocating sprayer. When the furniture board is separated from the two guide plates 3, the guide plates 3 will return to the initial state under the action of the spring; When painting furniture panels of different widths, the furniture panels will push the two guide plates 3 away from each other, and the guide plates 3 will drive the two baffles 35 to move away from each other along the first screw 23. Due to the different widths of the furniture panels, the distances by which the two guide plates 3 are pushed are different. When the two baffles 35 move away from each other, the slide plate 46 on the drive box 24 is pushed, which changes the moving direction of the drive box 24, so that the drive box 24 can move back and forth between the two baffles 35. Since the distance between the two guide plates 3 and the two baffles 35 is determined according to the width of the furniture panel, the distance between the guide plates 3 and the baffles 35 can be automatically adjusted according to the width of the panel, thereby automatically adjusting the reciprocating stroke of the drive box 24 and the nozzle 25, without manually adjusting the reciprocating stroke of the nozzle 25, and at the same time, the use range of the reciprocating paint sprayer can be increased.

[0018] Embodiment 2: A limit plate 5 is provided on the right side of the nozzle 25; the limit plate 5 is bent upward on the side away from the driving box 24; Both sides of the limit plate 5 extend above the two side plates 11; one side of the limit plate 5 extending to the side plate 11 is slidably connected to a third guide rod 51, and the bottom of the third guide rod 51 is fixedly connected to the side plate 11, and the top of the third guide rod 51 is fixedly connected to the chassis 13; The lower surface of the limit plate 5 is rotatably connected to a plurality of second rollers 52; a first notch 53 is provided on both guide plates 3 below the limit plate 5, and the second rollers 52 at the bottom of the limit plate 5 are in contact with the bottom of the first notch 53 in an initial state; The top of the limit plate 5 is fixedly connected to the evenly arranged support rods 54, and the other side of the support rod 54 is fixedly connected to the bottom of one of the U-shaped plates 2; In this embodiment, a rotating drum 55 is rotatably connected between two of the second rollers 52, and the diameter of the rotating drum 55 is smaller than the diameter of the second rollers 52; The outer ring of the rotating drum 55 is provided with evenly arranged air grooves 56; the upper part of the rotating drum 55 is provided with an air cavity 57, and the air cavity 57 is connected to an external air pump through a plurality of telescopic air pipes 58; In this embodiment, the left side of the rotating drum 55 is rotatably connected to a rotating rod 59; the rotating rod 59 is fixedly connected to a uniformly arranged brush layer 591; The limiting plate 5 has two rectangular grooves on one side close to one of the third guide rods 51; the second motors 592 are installed in the two rectangular grooves, and the two second motors 592 are used to drive the rotating drum 55 and the rotating rod 59 respectively; Specifically, when painting furniture panels of different thicknesses, since a limiting plate 5 is provided in the first notch 53 on the guide plate 3, when the furniture panel between the two guide plates 3 moves to below the limiting plate 5, the furniture panel will first contact the side of the limiting plate 5 that is bent upward, and then move along the second roller 52. When the panel gradually moves to below the limiting plate 5, the limiting plate 5 will be pushed to move upward along the third guide rod 51 as a whole. In the process of the limiting plate 5 moving upward, a plurality of support rods 54 will be driven to move upward. In the process of the support rods 54 moving upward, the U-shaped plate 2 will be pushed upward. At the same time, the U-shaped plate 2 will drive the mounting plate 21 to move upward along the first guide rod 22, and at the same time, the driving box 24 will be driven to move upward as a whole. This ensures that when painting panels of different thicknesses, the distance from the top end surface of the panel to the spray head 25 is the same. More specifically, when the furniture plate moves under the limit plate 5, the two second motors 592 are controlled to rotate counterclockwise, thereby driving the rotating drum 55 and the rotating rod 59 to rotate counterclockwise, and at the same time starting the external vacuum pump. When the vacuum pump extracts air, it will extract the gas in the air cavity 57. When the plate moves to the bottom of the rotating drum 55, the rotating drum 55 rotating counterclockwise at this time will drive the multiple air grooves 56 to rotate. The rotating air grooves 56 will suck the surface of the furniture plate, so as to extract the excess impurities on the furniture plate. At the same time, during the counterclockwise rotation of the rotating rod 59, the uniformly arranged brush layer 591 will be driven to rotate. The counterclockwise rotating brush layer 591 can brush the surface of the furniture plate. If there are still some impurities that have not been absorbed on the furniture plate, the counterclockwise rotating brush layer 591 can push these impurities to the position of the rotating drum 55, and then the air grooves 56 on the rotating drum 55 will suck the impurities again. By setting the limit plate 5, when it is necessary to spray paint on plates of different thicknesses, the moving plate will push the limit plate 5 to move upward, and the upward moving limit plate 5 will drive the U-shaped plate 2, the mounting plate 21, the drive box 24 and the nozzle 25 to move upward as a whole through multiple support rods 54. In this process, it can be ensured that when spraying paint on plates of different thicknesses, the distance from the top end surface of the plate to the nozzle 25 is the same, thereby avoiding differences in the paint liquid sprayed on the furniture plate due to changes in the distance between the nozzle 25 and the furniture plate.

[0019] Embodiment 3: An electric push rod 211 is installed on the end surface of one side of the two mounting plates 21 away from the third guide rod 51; the extension rod of the electric push rod 211 extends into the mounting plate 21 and abuts against the first guide rod 22; In this embodiment, a rotating belt 6 is provided below the two U-shaped plates 2, and the surface of the rotating belt 6 is fixedly connected to the water-absorbing cotton layer; One side of the transfer belt 6 is located below the U-shaped plate 2, and the other side extends out of the chassis 13; the transfer belt 6 extends out of one side of the chassis 13, and a collection box 61 is installed on the chassis 13; The side of the rotating belt 6 located below the U-shaped plate 2 rotates under the U-shaped plate 2 through the rotating shaft; the side of the rotating belt 6 located in the collecting box 61 rotates in the collecting box 61 through the rotating shaft and is driven by the third motor 62; The rotating belt 6 on the right side of the nozzle 25 extends into the first notch 53; below the rotating belt 6 on the left side of the nozzle 25, a second notch 63 is provided on both guide plates 3, and the rotating belt 6 on the left side extends into the second notch 63; In this embodiment, two squeezing rods 64 are rotatably connected in the collection box 61, and the squeezing rods 64 are in contact with the two rotating belts 6 respectively; Specifically, since the electric push rod 211 is fixedly connected to the mounting plate 21, when the furniture plate moves to the position directly below the limiting plate 5, the electric push rod 211 is controlled to extend and abut against the first guide rod 22. When the electric push rod 211 abuts against the first guide rod 22, the mounting plate 21 is fixed on the first guide rod 22. Since the limiting plate 5 is fixedly connected to the U-shaped plate 2 through the support rod 54, the position of the limiting plate 5 is also fixed. In this process, it can be avoided that the furniture plate needs to bear the gravity of the limiting plate 5, the U-shaped plate 2 and the drive box 24. At the same time, when the furniture plate is detached from the bottom of the limiting plate 5, since the positions of the mounting plate 21, the U-shaped plate 2 and the drive box 24 are fixed, the distance between the nozzle 25 and the furniture plate will not change. When the furniture plate is painted and removed from the reciprocating paint sprayer, the electric push rod 211 is controlled to return to its initial state. More specifically, during the process of spraying paint on the plate, due to the presence of the rotating belt 6, the rotating belt 6 can block the diffusion of the scattered paint liquid and prevent excessive paint liquid from diffusing into the external environment. At the same time, the third motor 62 is controlled to rotate. The rotating third motor 62 will drive the two rotating belts 6 to rotate in the first slot 53 and the second slot 63 respectively through the rotating shaft. Since the absorbent cotton layer is fixedly connected to the rotating belt 6, the diffused paint liquid can be absorbed. When the rotating belt 6 that absorbs the paint liquid rotates into the collecting box 61, the squeezing rod 64 will squeeze the passing absorbent cotton layer, so that the paint liquid absorbed by the absorbent cotton layer can be squeezed into the collecting box 61, thereby avoiding the absorbent cotton layer from absorbing the paint liquid for a long time and becoming saturated, thereby causing the paint liquid to drip.
