[0021] The beneficial effects of the present invention are: When the angle of the corrugated plate is too large or too small, two adjacent nozzles may interfere with each other. Therefore, when the connecting frame is adjusted at an excessively large angle, the connecting frame can be driven by transmission group 1 to move and be misaligned with the adjacent connecting frame, thereby avoiding the problem of multiple nozzles interfering with each other. While the connecting frame is moving, transmission group 2 will drive the nozzle to adjust its angle again, thereby ensuring that the spraying starting sections of multiple nozzles are always in one line.

[0022] When the aluminum plate to be sprayed moves to the bottom of the nozzle, multiple vertical rods move downward in turn to perform contour positioning on the corrugated aluminum plate. The downward movement of the vertical rods drives the connecting frame and the nozzle to move, and the movement of the connecting frame drives the push rods to move. After one end of one of the push rods contacts the aluminum plate, the vertical rod continues to push downward to drive the connecting frame and the nozzle to rotate and adjust. After both push rods contact the aluminum plate, they are locked to make the nozzle perpendicular to the aluminum plate surface, so that multiple nozzles are contoured and adjusted in turn, so that the distance between the nozzle and the corrugated plate is consistent, and the nozzle is always perpendicular to the aluminum plate, thereby improving the uniformity of spraying.

DETAILED DESCRIPTION

[0034] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] like Figures 1 to 10As shown, an aluminum plate coating device of the present invention includes a support plate 10 and a support frame 30. The support plates 10 are provided with two, and a conveyor belt 13 is arranged between the two support plates 10. The conveyor belt 13 is used to convey the aluminum plate to be sprayed. The support frame 30 is arranged above the support plate 10, and the support frame 30 is a U-shaped frame. Vertical rods 34 are arranged on the support frame 30 at intervals in the horizontal direction. In this embodiment, there are three vertical rods 34, and the vertical rods 34 can move up and down. Two adjacent vertical rods 34 can be dislocated in the length direction of the conveyor belt 13. The lower ends of the vertical rods 34 are provided with connecting frames 50, and the connecting frames 50 can be rotated and adjusted. Each connecting frame 50 is provided with a top rod 60 and the nozzle 51, the end of the top rod 60 can contact the aluminum plate, the nozzle 51 can spray the aluminum plate, and the support frame 30 is provided with a transmission group 1 and a transmission group 2, and the input ends of the transmission group 1 and the transmission group 2 are connected to the connecting frame 50, the output end of the transmission group 1 is connected to the vertical rod 34, and the output end of the transmission group 2 is connected to the nozzle 51, so that when the connecting frame 50 rotates too much toward the adjacent connecting frame 50, the corresponding vertical rod 34 can be driven by the transmission group 1 to move horizontally, so that the two adjacent connecting frames 50 are misaligned, and the transmission group 2 can drive the nozzle 51 to rotate while the vertical rod 34 moves, so as to ensure that the spraying of multiple nozzles 51 is always on a horizontal line.

[0036] When the aluminum plate to be sprayed moves to the bottom of the spray head 51, multiple vertical rods 34 move downward in turn to perform contour positioning on the corrugated aluminum plate. The downward movement of the vertical rods 34 drives the connecting frame 50 and the spray head 51 to move. The movement of the connecting frame 50 drives the push rod 60 to move. After one end of one push rod 60 contacts the aluminum plate, the vertical rod 34 continues to push downward to drive the connecting frame 50 and the spray head 51 to rotate and adjust. After both push rods 60 contact the aluminum plate, they are locked to make the spray head 51 perpendicular to the aluminum plate surface, so that multiple spray heads 51 are contoured and adjusted in turn, so that the distance between the spray head 51 and the corrugated plate is consistent. At the same time, the spray head 51 is always perpendicular to the aluminum plate, thereby improving the uniformity of spraying.

[0037] When the angle of the corrugated plate is too large or too small, two adjacent nozzles 51 may interfere with each other. Therefore, when the connecting frame 50 is adjusted at an angle too large, the connecting frame 50 can be driven by the transmission group 1 to move and be misaligned with the adjacent connecting frame 50, thereby avoiding the problem of interference of the nozzles 51. While the connecting frame 50 moves, the transmission group 2 will drive the nozzles 51 to adjust the angle again, thereby ensuring that the spraying of multiple nozzles 51 is always in a line. At the same time, the misalignment setting helps to optimize the distribution of water flow or air flow, reduce the distance between multiple nozzles 51 being too close, and reduce the interactive turbulence in the spraying range, thereby improving the spraying efficiency and effect.

[0038] like Figures 3 to 5As shown, a support rod 14 is provided on the top of the support plate 10, and there are multiple support rods 14, and the multiple support rods 14 are distributed in a rectangular shape. A top plate 15 is provided between the multiple support rods 14, and the support rods 14 are used to support the top plate 15, and a support frame 30 is provided on the lower surface of the top plate 15. The support frame 30 is composed of a horizontal plate and two vertical plates, and the U-shaped opening of the support frame 30 faces the lower surface of the top plate 15, and vertical rods 34 are arranged at intervals on the support frame 30.

[0039] like Figures 4 to 5 As shown, a sliding plate 40 is sleeved on the outer peripheral side of the vertical rod 34, and the vertical rod 34 can slide up and down in the height direction of the sliding plate 40. A vertical slide groove 41 is provided on the sliding plate 40, and a first slide bar 36 is provided on one side of the vertical rod 34, and the first slide bar 36 cooperates with the vertical slide groove 41, so that the sliding of the vertical rod 34 is more stable. A driving component is provided on the sliding plate 40, and the driving component can move the vertical rod 34 up and down. The driving component includes a motor 43, and the motor 43 is arranged on the top of the sliding plate 40. A rotating shaft 44 is provided at the output end of the motor 43, and a first gear 45 is provided at one end of the rotating shaft 44. The vertical side surface of the vertical rod 34 is provided with teeth 35. It should be noted in this embodiment that The teeth 35 on the vertical rod 34 located in the middle position are opposite to the teeth 35 on the vertical rods 34 on both sides and the driving assembly, and the teeth 35 are meshed with the first gear 45. The first sliding grooves 37 are spaced apart on the horizontal plate of the support frame 30. The first sliding grooves 37 correspond to the vertical rods 34 one by one. The vertical rods 34 can slide along the width direction of the horizontal plate inside the first sliding grooves 37. A second sliding groove 38 is provided on the top of the horizontal plate of the support frame 30, and the second sliding grooves 38 are located on both sides of the first sliding grooves 37. A second slide bar 42 is provided at the bottom of the sliding plate 40. The second slide bar 42 slidably cooperates with the second slide groove 38 so that the sliding plate 40 can slide along the width direction on the horizontal plate of the support frame 30.

[0040] When the vertical rod 34 is lifted or lowered, the motor 43 drives the shaft 44 to rotate, and the rotation of the shaft 44 drives the first gear 45 to rotate. The teeth 35 mesh with the first gear 45, and the rotation of the first gear 45 can drive the corresponding vertical rod 34 to move up and down.

[0041] like Figure 6 to Figure 7As shown, a first rotating rod 54 is rotatably provided at the lower end position of the vertical rod 34, and the first rotating rod 54 runs through both sides of the vertical rod 34. Both ends of the first rotating rod 54 are connected to the connecting frame 50. The rotation of the first rotating rod 54 can drive the connecting frame 50 to rotate to achieve angle adjustment of the connecting frame 50. A limiting strip 81 is provided inside the vertical rod 34. The limiting strip 81 can limit and fix the first rotating rod 54, thereby achieving the fixing of the adjusted angle of the connecting frame 50. A torsion spring 80 is provided at the connection between the vertical rod 34 and the first rotating rod 54. In order to reset it after adjusting the angle, a fixing block 62 is provided on the outer side of the connecting frame 50. The top rod 60 is provided on the fixing block 62, and the top rod 60 is provided in a V shape. The end of the top rod 60 is provided with an anti-slip cap 61, which has the effect of increasing friction.

[0042] When the vertical rod 34 drives the connecting frame 50 to move downward, the connecting frame 50 drives the fixing block 62 and the push rod 60 to move, and the movement of the push rod 60 drives the anti-slip cap 61 to move downward. Since the aluminum plate is wavy, one end of the push rod 60 contacts the aluminum plate first, so that one of the anti-slip caps 61 contacts the aluminum plate first, and then the vertical rod 34 pushes downward again, so that the connecting frame 50 rotates passively, and the rotation of the connecting frame 50 drives the first rotating rod 54 to rotate, so that the other push rod 60 contacts the aluminum plate. When the ends of the two push rods 60 contact the aluminum plate, the angle adjustment of the connecting frame 50 is completed, and the adjusted angle of the connecting frame 50 is fixed by the limit strip 81. The angle of the nozzle 51 below the connecting frame 50 is the spraying angle, so that each nozzle 51 is always perpendicular to the aluminum plate, and the push rod 60 can ensure that the distance from the nozzle 51 to the aluminum plate is consistent, so that when spraying, the spraying effect of multiple nozzles 51 is good and the spraying is more uniform.

[0043] like Figures 6 to 8 As shown, the transmission group 2 includes a pull rope 58 and a special-shaped bevel gear 55. The outer peripheral surface of the first rotating rod 54 is provided with a special-shaped bevel gear 55, and the special-shaped bevel gear 55 is provided with partial bevel teeth, such as Fig. 9 The special-shaped bevel gears 55 located on both sides are shown, which need to be explained ( Fig.10 ) is a schematic diagram of partial bevel teeth on the special-shaped bevel gear 55 located at the position of the middle vertical rod 34. The side wall of the vertical rod 34 is provided with a fixing plate, and the fixing plate is provided with a second rotating rod 57. The outer peripheral surface of the second rotating rod 57 is provided with a bevel gear 56, and the bevel gear 56 can mesh with the special-shaped bevel gear 55. A third rotating rod 59 is provided inside the connecting frame 50, and one end of the third rotating rod 59 extends out of the outside of the connecting frame 50 (as shown in FIG. Figure 6As shown in the figure, a second torsion spring is also provided at the position of the third rotating rod 59 and the connecting frame 50. The second torsion spring is used to reset the third rotating rod 59. The principle of the second torsion spring is basically the same as the above principle, so it is not repeated here. The nozzle 51 is provided on the outer peripheral surface of the third rotating rod 59. The third rotating rod 59 can drive the nozzle 51 to swing left and right to adjust the angle, so that when the connecting frame 50 is dislocated, the spraying range of multiple nozzles 51 is in a straight line. A pull rope 58 is provided on the outer peripheral surface of the third rotating rod 59, and one end of the pull rope 58 is connected to the second rotating rod 57.

[0044] like Figures 4 to 8 As shown, the transmission group 1 includes a transmission gear 47 and a rack plate 46. The horizontal plates of the support frame 30 are spaced apart with transmission gears 47, and the transmission gears 47 correspond to the sliding plates 40 one by one. The rack plates 46 are respectively arranged on the side walls of the sliding plates 40 on both sides, and the transmission gears 47 are meshed with the rack plates 46. One end of the first rotating rod 54 extends out of one side of the connecting frame 50, and a second bevel gear 70 is arranged on the outer peripheral surface of the end extending from the first rotating rod 54, so that the connecting frame 50 can drive the second bevel gear 70 to rotate when the angle is adjusted. An electric push rod is arranged on the outer wall of one side of the sliding plate 40 at the middle position, and a signal sensor is arranged on the top of the support frame 30. The electric push rod is controlled by a signal sensor. The transmission gear 47 in the middle position can feedback the signal sensor to control the movement of the sliding plate 40 clockwise or counterclockwise, thereby realizing the movement of the sliding plate 40 in the middle position and forming a misalignment with the two sides. The lower wall of the transmission gear 47 is provided with a spline cylinder 73, and the internal sliding sleeve of the spline cylinder 73 is provided with a spline 72, and the spline 72 can cooperate with the spline cylinder 73 so that it can still be in a transmission connection after profiling. A third bevel gear 71 is provided at the bottom end of the spline 72, and the third bevel gear 71 is meshed with the second bevel gear 70. It should be noted that in this embodiment, the transmission group 1 in the middle position is opposite to the transmission group 1 on both sides.

[0045] When the angle of the corrugated plate is too large or close, the two nozzles 51 may interfere with each other. Therefore, when the connecting frame 50 rotates too much toward the adjacent connecting frame 50 position, in order to avoid the nozzles 51 interfering with each other, the connecting frame 50 drives the first rotating rod 54 to rotate, and the rotation of the first rotating rod 54 drives the special-shaped bevel gear 55 and the second bevel gear 70 to rotate, and the rotation of the second bevel gear 70 drives the third bevel gear 71 to rotate, and the rotation of the third bevel gear 71 drives the spline 72 to rotate, and the spline 72 cooperates with the spline cylinder 73, so that the rotation of the spline 72 drives the spline cylinder 73 to rotate, and the rotation of the spline cylinder 73 drives the transmission gear 47 to rotate. Since the transmission gear 47 is meshed with the rack plate 46, the transmission gear 47 drives the rack plate 46 to move, and the movement of the rack plate 46 drives the sliding plate 40 to move, and the movement of the sliding plate 40 drives the vertical rod 34 and the connecting frame 50 to move, so that the entire nozzle 51 located on the side moves, and the two nozzles 51 are misaligned, thereby avoiding the problem of interference between the two nozzles 51.

[0046] At the same time, in order to avoid the misalignment of the nozzle 51 so that the spraying range is not in a straight line, the first rotating rod 54 rotates to drive the special-shaped bevel gear 55 to rotate, and the rotation of the special-shaped bevel gear 55 drives the bevel gear 56 to rotate. The rotation of the bevel gear 56 will reel in the stirring rope 58, and the reeling of the rope 58 drives the third rotating rod 59 to rotate. The rotation of the third rotating rod 59 drives the nozzle 51 to rotate, so as to achieve the angle adjustment of the nozzle 51. At the same time, the misaligned setting helps to optimize the distribution of water flow or air flow and reduce the interactive turbulence, thereby improving the spraying efficiency and effect.

[0047] like Figure 1 to Figure 2 As shown, a support leg 11 is provided at the bottom of the support plate 10, and the support leg 11 is used to support the support plate 10. A motor 12 is provided on the outer side of the support plate 10, and the motor 12 is used to drive the conveyor belt 13 to rotate, so as to convey the aluminum plate. A support plate 20 is provided on the outer side of the support plate 10, and a tank body 21 is provided on the top of the support plate 20. The tank body 21 is filled with paint, and a liquid outlet pipe 22 is provided on the top of the tank body 21. The liquid outlet pipe 22 is used to convey the extracted paint, and a telescopic hose is provided on the liquid outlet pipe 22, and the telescopic hose is connected to multiple nozzles 51 through it.

[0048] An aluminum plate coating device and coating method of the present invention include: S1, placing the aluminum plate to be sprayed on the conveyor belt 13, and pausing the movement when the aluminum plate is moved to the bottom of the spray head 51 by the conveyor belt 13; S2, multiple vertical rods 34 move downward in sequence to perform contour positioning on the corrugated aluminum plate, and the vertical rods 34 drive the nozzle 51 and the top rod 60 to contact the aluminum plate, thereby realizing the angle adjustment of the nozzle 51 and the adjustment of the distance between the nozzle 51 and the aluminum plate, thereby ensuring the uniformity of the coating device for spraying the corrugated plate and improving the spraying effect; S3. In order to avoid the two nozzles 51 from interfering with each other during profiling, the transmission group 1 can drive the connecting frame 50 to move so that it is misaligned with the adjacent connecting frame 50, thereby avoiding the problem of interference between the adjacent nozzles 51; S4, the transmission group 2 will drive the nozzle 51 to adjust the angle again, so as to ensure that the spraying of multiple nozzles 51 is always in a line.
