Description

Technical Field

[0001] The invention relates to the technical field of spraying devices, and in particular to a spraying device for a wear-resistant layer of a fan blade. Background Art

[0002] A fan blade is a thin shell structure made of composite materials. The fan blade is mainly designed for various types of fans. Different fans are provided with different fan blades. The manufacturing process of the fan blade mainly includes manufacturing molding molds, laying layers, heating and curing, demoulding, surface grinding and painting, etc. The painting of the fan blade can improve the appearance, wear resistance, aging resistance and corrosion resistance of the fan blade, and improve the performance of the fan blade.

[0003] After searching, the Chinese patent application number CN202110865453.0 discloses an automatic processing system for the surface of a fan blade, including a base plate, a paint spraying device and a positioning device. A paint spraying device is installed on the base plate, and a positioning device is installed in the paint spraying device. However, since the above technical scheme requires the use of multiple paint spraying pipelines such as inclined nozzles and paint spraying pipes to spray paint on the surface of the fan blades, the paint pump needs to fill more paint into multiple paint spraying pipelines so that multiple paint spraying pipelines can spray out sufficient paint to spray the surface of the fan blades. This will greatly increase the amount of paint required for spraying the fan blades, and manual painting only requires the staff to hold a spray gun on one side to complete the painting of the fan blades. Therefore, the automatic painting equipment uses a high amount of paint, which leads to a large amount of paint waste and increases the cost of fan blade spraying. Summary of the invention

[0024] The staff first opens the sealing door 6, then inserts the fan blade body 18 to be sprayed into the corresponding position of the outer wall of the rotating shaft 9, then closes the sealing door 6, and controls the motor 7 to drive the rotating shaft 9 to rotate at a constant speed through the control panel on the outer wall of the sealing box 5, and controls the operation of the paint transmission mechanism to transport the spray liquid to the nozzle 20, and then sprays it out through the nozzle 19; When the motor 7 starts to drive the rotating shaft 9 to rotate, the nozzle 19 is at the initial height, and the fan blade body 18 will rotate at a uniform speed driven by the rotating shaft 9, so that the nozzles 19 on both sides of the fan blade body 18 can spray the outermost circle of the fan blade body 18. When the fan blade body 18 rotates 360 degrees driven by the rotating shaft 9, the outermost circle of the fan blade body 18 will be completely sprayed by the nozzle 19. At the same time, after the rotating shaft 9 rotates 360 degrees, it will drive the first gear 8 of the outer wall to rotate together, thereby driving the first gear 8 to drive the first tooth plate 10 meshing with it to move forward a corresponding distance. When the first tooth plate 10 moves forward, it will drive the mounting frame 32 slidably connected to the outer wall to slide forward under the guidance of the guide frame 16, thereby pulling the airbag 11 forward through the mounting frame 32 and the first connecting frame 46. When the airbag 11 is stretched, it will absorb external gas through the air intake check valve 49 on one side; When the first gear 8 rotates 360 degrees driven by the rotating shaft 9, the collision pushing mechanism located on the inner wall of the mounting frame 32 will drive the first tooth plate 10 to move downward a corresponding distance as a whole, thereby releasing the meshing between the first tooth plate 10 and the first gear 8, and at the same time allowing the fourth tooth plate 41 at the bottom of the first tooth plate 10 to move to the third gear 35 on one side of the support rod 17, so that the third gear 35 and the fourth tooth plate 41 are meshed. At this time, the control panel will control the motor 7 to drive the rotating shaft 9 to rotate continuously, so that the fourth tooth plate 41 as a whole moves back driven by the rotating third gear 35. When the fourth tooth plate 41 moves back, it will drive the mounting frame 32 slidably connected to the outer wall to move back as a whole. When the mounting frame 32 moves back, it will push the first connecting frame 46 to the airbag 11 stretched on one side. The air bag 11 is squeezed, and the gas absorbed by the air bag 11 through the inlet check valve 49 is filled into the cylinder 28 through the outlet check valve 31 and the first air guide pipe 12, so that the cylinder 28 pushes the fixed-distance moving mechanism to drive the connecting frame 22 to move downward by a corresponding distance and then stop, so that the motor 7 drives the fan blade body 18 to rotate 360 ​​degrees each time, and the fixed-distance moving mechanism can drive the connecting frame 22 to drop a certain distance as a whole, so that the nozzles 19 on both sides of the fan blade body 18 can start from the outermost circle of the fan blade body 18 to spray the outer wall of the rotating fan blade body 18 comprehensively, so that the outer wall of the fan blade body 18 is fully sprayed under the premise of using only a pair of nozzles 19, while reducing the amount of paint, the spraying processing efficiency of the fan blade body 18 is improved; When the motor 7 drives the fan blade body 18 to rotate a corresponding number of circles, the connecting frame 22 will also move downward a corresponding distance driven by the fixed-distance moving mechanism, so that the nozzle 19 can also complete the spraying of the central part of the fan blade body 18. At this time, the staff can control the electric control valve 38 through the control panel to open the valve connected to the exhaust pipe 37. At this time, the internal gas of the cylinder 28 will be discharged under the squeezing of the fixed-distance moving mechanism, so that the fixed-distance moving mechanism drives the connecting frame 22 to move upward and reset, so that the nozzle 19 is raised to a height that no longer blocks the fan blade body 18. At this time, the staff can open the sealing door 6 to take out the fan blade body 18 after spraying, and then insert the next fan blade body 18 that needs to be sprayed on the rotating shaft 9 for further processing.

[0025] like Figure 4 and Figure 6-8 As shown, the collision pushing mechanism includes an arc-shaped top block 39, a slide bar 40, a second collision head 50, a first collision head 33, a first baffle 14, a second baffle 36, an arc-shaped spring piece 45 and a guide rail 44. The arc-shaped top block 39 is slidably connected to the bottom inner wall of the mounting frame 32, the slide bar 40 is fixed to the inner wall of the arc-shaped top block 39, the slide bar 40 runs through the outer walls on both sides of the mounting frame 32, and the length difference between the slide bar 40 and the mounting frame 32 is greater than or equal to the length of the arc-shaped top block 39. The second collision head 50 and the first collision head 33 are respectively fixed to the outer walls on both sides of the slide bar 40, one end of the arc-shaped spring piece 45 is fixed to the bottom outer wall of the first toothed plate 10, and the other end of the arc-shaped spring piece 45 is slidably connected to the bottom outer wall of the first toothed plate 10, the guide rail 44 is fixed to the bottom outer wall of the first toothed plate 10, and the second baffle 36 and the first baffle 14 are respectively fixed to the outer wall of the guide frame 16; When the first gear 8 in continuous rotation drives the first toothed plate 10 to move forward a corresponding distance, the first collision head 33 protruding from the mounting frame 32 on one side of the slide bar 40 will collide with the second baffle plate 36, so that the slide bar 40 pushes the arc-shaped top block 39 to move toward the side of the arc-shaped spring piece 45, staggering the arc-shaped top block 39 and the arc-shaped spring piece 45. At this time, the arc-shaped top block 39 will no longer support the arc-shaped spring piece 45, so that the first toothed plate 10 can slide downward as a whole until the fourth toothed plate 41 at the bottom of the first toothed plate 10 slides to the outer wall of the third gear 35. At this time, the third gear 35 rotating in the same direction as the first gear 8 will drive the fourth toothed plate 41 to move in the opposite direction, thereby driving the mounting frame 32 to move back as a whole. When the second collision head 50 on the other side of the slide bar 40 moves to the side of the first baffle plate 14, it will collide with the first baffle plate 14. 14 collides, thereby pushing the slide bar 40 to move forward a corresponding distance as a whole, so that the arc-shaped top block 39 can move back to the bottom of the arc-shaped spring piece 45 to support the arc-shaped spring piece 45, so that the first tooth plate 10 can move upward under the support of the arc-shaped spring piece 45 and re-engage with the first gear 8, so that the rotating shaft 9 that continuously drives the fan blade body 18 to rotate in the same direction can drive the mounting frame 32 to move back and forth, so that the mounting frame 32 can stably drive the airbag 11 to switch between extension and contraction, so that every time the rotating shaft 9 drives the fan blade body 18 to rotate 360 ​​degrees, a certain amount of gas will be filled into the cylinder 28; at the same time, the elasticity of the arc-shaped spring piece 45 itself can buffer the vibration generated when the first tooth plate 10 and the first gear 8 contact, thereby improving the stability of the mounting frame 32 when switching back and forth.

[0026] like Figure 3-5 As shown, the fixed-distance moving mechanism includes a counterweight, a third toothed plate 29, a support frame 30, a second gear 27 and a second toothed plate 26. The third toothed plate 29 is fixed to the output shaft of the cylinder 28, the counterweight is fixed to the outer wall of the third toothed plate 29, the support frame 30 is fixed to the outer wall of the mounting frame 21, the second gear 27 is rotatably connected to the outer wall of the support frame 30, the second toothed plate 26 is fixed to the outer wall of the connecting frame 22, and the second toothed plate 26 and the third toothed plate 29 are respectively meshed and connected with the second gear 27; when the cylinder 28 pushes the third toothed plate 29 to After moving up a certain distance, the third tooth plate 29 will drive the second tooth plate 26 to move downward a corresponding distance through the second gear 27, thereby driving the connecting frame 22 to move downward a corresponding distance. When the control panel controls the electric control valve 38 to open one side of the exhaust pipe 37, the overall weight of the external counterweight block of the third tooth plate 29 is greater than the overall weight of the connecting frame 22 and the second tooth plate 26. At this time, the third tooth plate 29 will move downward under the gravity of the counterweight block, squeezing out the gas inside the cylinder 28, while driving the connecting frame 22 to move upward and reset through the second gear 27.

[0027] like Figure 3-4As shown, the paint transmission mechanism includes a liquid storage tank 25, a paint pump, a material guide pipe 24 and a telescopic bellows 23. The liquid storage tank 25 is fixed on the top outer wall of the mounting frame 21, the paint pump is connected to the outer wall of the liquid storage tank 25 through a pipeline, the material guide pipe 24 is connected to the output end of the paint pump through a connecting valve, the telescopic bellows 23 is arranged on the outer wall on the opposite side of the material guide pipe 24 and the nozzle 20, and the paint pump is electrically connected to the control panel; the control panel will control the paint pump to extract the spray liquid inside the liquid storage tank 25 and spray it into the nozzle 20, so that the outer wall of the rotating fan blade body 18 is sprayed through the nozzle 19 on one side of the nozzle 20.

[0028] like Figure 7 As shown, springs 43 are fixed to the inner walls on both sides of the installation frame 32, and the top outer wall of the spring 43 is fixed to the bottom outer wall of the first tooth plate 10; rubber blocks 42 are fixed to the inner walls on both sides of the installation frame 32; when the arc-shaped top block 39 leaves one side of the arc-shaped spring piece 45 driven by the slide rod 40, the first tooth plate 10 as a whole will move downward rapidly under the elastic force of the spring 43, so that the fourth tooth plate 41 can quickly engage with the third gear 35, and the rubber block 42 can buffer and limit the first tooth plate 10 that moves downward rapidly.

[0029] like Figure 6-7 As shown, a guide frame 13 is fixed to the outer wall of the first connecting frame 46, and guide rods 48 are respectively fixed to the outer walls of the two sides of the support plate 15, and the guide frame 13 is slidably connected to the outer wall of the guide rod 48; when the first connecting frame 46 moves back and forth driven by the installation frame 32, the guide frame 13 located on the outer wall of the first connecting frame 46 will slide back and forth on the outer wall of the guide rod 48, thereby guiding the first connecting frame 46 and the installation frame 32, and improving the stability of the first connecting frame 46 when moving back and forth.

[0030] When using this embodiment, the staff first opens the sealing door 6, then inserts the fan blade body 18 to be sprayed into the corresponding position of the outer wall of the rotating shaft 9, then closes the sealing door 6, and controls the motor 7 to drive the rotating shaft 9 to rotate at a constant speed through the control panel on the outer wall of the sealing box 5, and controls the operation of the paint transmission mechanism to transport the spray liquid to the nozzle 20, and then sprays it outward through the nozzle 19; When the motor 7 starts to drive the rotating shaft 9 to rotate, the nozzle 19 is at the initial height, and the fan blade body 18 will rotate at a uniform speed driven by the rotating shaft 9, so that the nozzles 19 on both sides of the fan blade body 18 can spray the outermost circle of the fan blade body 18. When the fan blade body 18 rotates 360 degrees driven by the rotating shaft 9, the outermost circle of the fan blade body 18 will be completely sprayed by the nozzle 19. At the same time, after the rotating shaft 9 rotates 360 degrees, it will drive the first gear 8 of the outer wall to rotate together, thereby driving the first gear 8 to drive the first tooth plate 10 meshing with it to move forward a corresponding distance. When the first tooth plate 10 moves forward, it will drive the mounting frame 32 slidably connected to the outer wall to slide forward under the guidance of the guide frame 16, thereby pulling the airbag 11 forward through the mounting frame 32 and the first connecting frame 46. When the airbag 11 is stretched, it will absorb external gas through the air intake check valve 49 on one side; When the first gear 8 rotates 360 degrees driven by the rotating shaft 9, the collision pushing mechanism located on the inner wall of the mounting frame 32 will drive the first tooth plate 10 to move downward a corresponding distance as a whole, thereby releasing the meshing between the first tooth plate 10 and the first gear 8, and at the same time allowing the fourth tooth plate 41 at the bottom of the first tooth plate 10 to move to the third gear 35 on one side of the support rod 17, so that the third gear 35 and the fourth tooth plate 41 are meshed. At this time, the control panel will control the motor 7 to drive the rotating shaft 9 to rotate continuously, so that the fourth tooth plate 41 as a whole moves back under the drive of the rotating third gear 35. When the fourth tooth plate 41 moves back, it will drive the mounting frame 32 slidably connected to the outer wall to move back as a whole. When the mounting frame 32 moves back, it will push the first connecting frame 46 to squeeze the airbag 11 that has been stretched on one side, so that the gas absorbed by the inside of the airbag 11 through the air inlet check valve 49 is filled into the cylinder 28 through the air outlet check valve 31 and the first air guide pipe 12, so that the cylinder 28 pushes the fixed-distance moving mechanism to drive the connecting frame 22 to move downward a corresponding distance and then stop, so that every time the motor 7 drives the fan blade body 18 to rotate 360 ​​degrees, the fixed-distance moving mechanism can drive the connecting frame 22 to drop a certain distance as a whole, so that the nozzles 19 on both sides of the fan blade body 18 can start from the outermost circle of the fan blade body 18 to spray the outer wall of the rotating fan blade body 18 comprehensively.

[0031] When the motor 7 drives the fan blade body 18 to rotate a corresponding number of circles, the connecting frame 22 will also move downward a corresponding distance driven by the fixed-distance moving mechanism, so that the nozzle 19 can also complete the spraying of the central part of the fan blade body 18. At this time, the staff can control the electric control valve 38 through the control panel to open the valve connected to the exhaust pipe 37. At this time, the internal gas of the cylinder 28 will be discharged under the squeezing of the fixed-distance moving mechanism, so that the fixed-distance moving mechanism drives the connecting frame 22 to move upward and reset, so that the nozzle 19 is raised to a height that no longer blocks the fan blade body 18. At this time, the staff can open the sealing door 6 to take out the fan blade body 18 after spraying.
