Description

Technical Field

[0001] This invention relates to the field of spraying equipment technology, specifically to an automated spraying device for coating fluids on the surface of silicon carbide products. Background Technology

[0002] Silicon carbide products are various items or products made of silicon carbide material. Silicon carbide is a special ceramic material with excellent physical properties such as high temperature resistance, corrosion resistance and hardness. Therefore, it is widely used in many fields. Common silicon carbide products include silicon carbide ceramics, silicon carbide fibers and silicon carbide coatings.

[0003] When using a silicon carbide product coating and spraying device, the coating is difficult to evenly cover the surface of the workpiece due to the limitations of the workpiece's shape, especially internal depressions or curved areas. This can result in some areas not being coated or being insufficiently coated. To address these issues, the following solutions are proposed. Summary of the Invention

[0017] The present invention has the following beneficial effects:

[0018] 1. This invention discloses an automated spraying device for coating fluid on the surface of silicon carbide products. It includes a rotating mechanism. When coating is required on the silicon carbide product, a motor is started, driving a rotating rod to rotate. This rotation of the rotating rod then drives a connecting frame to rotate. Several gears mesh with gear one, and the rotation of the connecting frame causes several cylindrical parts to rotate. This rotation of the cylindrical parts causes the silicon carbide product to rotate during coating. For complex-shaped silicon carbide products, traditional spraying methods struggle to coat internal recesses or curved surfaces. Rotating the coating device allows for better coverage of these hard-to-reach areas, ensuring uniform coating across the entire product surface. This uniform coating helps avoid uneven thickness, missed areas, or repeated coating, thereby improving the overall quality and appearance of the product.

[0019] 2. This invention discloses an automated spraying device for coating fluid on the surface of silicon carbide products. By incorporating a limit assembly, a spring assembly, and an adjustment assembly, and featuring a conical top plate with one side thinner than the other, when the sliding rod touches the thinner side of the conical top plate, the force on the spring is released, causing the sliding rod to move several movable strips. These movable strips then place the workpiece to be coated onto a cylindrical sleeve. Driven by a motor, the sliding rod moves to the thicker side of the conical top plate, causing it to move downwards. This downward movement opens the movable strips, limiting the bottom of the workpiece and preventing it from falling during coating. Through the design of the conical top plate, in conjunction with a drying device, when the sliding rod moves to the thinner side of the conical top plate, the movable strips retract... The coating is compressed, causing the coated workpiece to slide onto the drying equipment for drying. Automatic unloading reduces the need for manual operation, making the production process more continuous and automated. This significantly improves the production line's operating speed and production capacity, especially in mass production. Starting the motor drives rotor one to rotate, which in turn drives rotor two via two bevel gears. Rotor two, through pulleys and belts, drives rotor three to rotate. The rotation of rotor three causes the turntable to rotate, which in turn moves the control lever up and down, thus moving the slider. By adjusting the slider's up and down movement, the angle of the spray nozzle can be adjusted, ensuring a uniform coating distribution on the silicon carbide product surface and preventing uneven coating, thus improving coating uniformity and coverage.

[0020] 3. This invention provides an automated spraying device for coating fluid on the surface of silicon carbide products. It includes a compression mechanism and an anti-clogging component. Two rotating rods (3) rotate simultaneously, driving a rotating plate and a rotating shaft (2). The rotation of the rotating plate and shaft (2) causes an adjusting block to move, which in turn causes a piston to reciprocate. When the piston moves downwards, a negative pressure is created inside the compression tank. This pressure difference causes a circular plate (1) to open, drawing in outside air. When the piston moves upwards, it compresses the gas inside the compression tank, increasing the gas pressure. This increased pressure causes the circular plate (2) to open, allowing the compressed gas to be delivered to the spraying cylinder through an outlet pipe. When the compression... When gas is blown towards the sealing plate, it causes spring 4 to be pushed, which in turn causes the two sealing plates 45 to rotate around the hinge. After the two 45 rotate, compressed air is blown towards the paint. When the spraying device is not in use, the gas supply stops, and the pushing force on spring 4 disappears. Spring 4 then moves the sealing plate back to its original position, thus ensuring that the spraying cylinder remains sealed when the device is not in use. This prevents the paint from curing inside the spraying cylinder, avoids clogging of the spraying cylinder, and prevents nozzle clogging from affecting the uniformity and accuracy of spraying, thereby improving the uniformity and accuracy of the spraying device.

[0021] 4. This invention provides an automated spraying device for coating fluid on the surface of silicon carbide products. It includes a cleaning component. After the coating is poured into a storage cylinder, the coating adheres to the inner wall of the cylinder. The coating adsorbed on the inner wall needs to be cleaned. Simultaneously, a motor drives a rotating rod to rotate, which in turn drives a connecting frame. The rotating frame then drives a conical block to rotate. The conical block has a design where one side is higher than the other. When the conical block 54 rotates, and the higher side slides against the sliding rod 56, it causes the sliding rod 56 to move downwards. When the lower side of block 54 slides with slide bar 56, it can drive slide bar 56 to move upward, thereby driving slide bar 56 and scraper 55 to rise or fall. After slide bar 56 moves up and down, it can drive scraper 55 to scrape and clean the paint adsorbed on the inner wall of storage cylinder 53, avoiding paint accumulation on the inner wall of storage cylinder 53. Preventing paint adsorption on the inner wall of storage cylinder can minimize paint waste, ensure that more paint is used effectively, thereby improving paint utilization rate and further improving the coating effect and coating quality of the device.

[0022] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1 - Figure 8 As shown, the present invention is an automated spraying device for coating fluid on the surface of silicon carbide products, including a base 1 and a conical top plate 2 disposed above the base 1. The base 1 is provided with a rotating mechanism, a transmission mechanism, a compression mechanism and a spraying mechanism.

[0036] The rotating mechanism includes a rotating component, several limiting components, and a spring component. The rotating mechanism includes several support plates 3 fixedly installed on the top of the base 1. The sides of the several support plates 3 that are close to each other are fixedly connected to the conical top plate 2. A motor 4 is fixedly installed on the top of the conical top plate 2. A support column 6 is fixedly installed on the top of the base 1. A rotating rod 7 is rotatably installed inside the support column 6. The rotating rod 7 passes through the support column 6 and is fixedly connected to the output shaft of the motor 4. A connecting frame 8 is fixedly sleeved on the outer wall of the rotating rod 7. A gear 9 is fixedly sleeved on the outer wall of the support column 6. Several cylindrical cylinders 10 are rotatably installed at the bottom of the connecting frame 8. Gears 11 are fixedly sleeved on the outer walls of the several cylindrical cylinders 10 respectively. The several gears 11 mesh with gears 9.

[0037] like Figure 3 and Figure 4 As shown, the limiting component includes a slide rod 12 slidably installed inside the cylindrical cylinder 10. The slide rod 12 passes through the connecting frame 8 and is slidably connected to the connecting frame 8. The bottom of the cylindrical cylinder 10 has several movable slots 13. A rotating shaft 14 is rotatably installed in each of the several movable slots 13. Movable strips 15 are rotatably sleeved on each of the several rotating shafts 14. The tops of the several movable strips 15 are all hinged to the slide rod 12. By setting the limiting component and the design of the conical top plate 2 being thin on one side and thick on the other, when the slide rod 12 touches the thin side of the conical top plate 2, the force on the spring 17 is released, thereby causing the slide rod 12 to drive the several movable strips 15 to move. After the several movable strips 15 move, they can put the workpiece to be coated onto the cylindrical cylinder 10.

[0038] like Figure 3 and Figure 4 As shown, the spring assembly includes annular plates 16 fixedly sleeved on the outer walls of several slide rods 12, springs 17 wound around the slide rods 12, the bottom ends of the springs 17 being fixedly connected to the annular plates 16, and the top ends of the springs 17 being fixedly connected to the connecting frame 8. Annular blocks 18 are fixedly installed at the bottom of the conical top plate 2, and the bottom of the annular blocks 18 is slidably connected to the slide rods 12. By setting the spring assembly, automatic feeding can be achieved through the combined use of the annular plates 16, springs 17, and annular blocks 18. Automatic feeding can reduce the need for manual operation, making the production process more continuous and automated. This can significantly improve the operating speed and production capacity of the production line, especially in the case of mass production.

[0039] like Figure 2As shown, the transmission mechanism includes a through groove 19 opened in the base 1. Two connecting plates 20 are fixedly installed on the top inner wall of the through groove 19. A rotating rod 21 is rotatably installed on the two connecting plates 20. A bevel gear 22 is fixedly sleeved on the rotating rod 21 and the rotating rod 7 respectively. The two bevel gears 22 mesh with each other. Through the transmission mechanism, the motor 4 is started. The motor 4 drives the rotating rod 7 to rotate. After the rotating rod 7 rotates, it drives the rotating rod 21 to rotate through the two bevel gears 22.

[0040] like Figure 5 and Figure 6 As shown, the compression mechanism includes a belt assembly, a compression assembly, and a gas delivery assembly. The belt assembly includes a compression tank 23 fixedly installed on the top of the base 1. Two rotating rods 24 are rotatably installed inside the compression tank 23. The ends of the corresponding rotating rods 24 extend to the outside of the compression tank 23 and are rotatably connected to the compression tank 23. Pulleys 25 are fixedly sleeved on the rotating rods 24 and 21 respectively. Belts 26 are wound on the two pulleys 25. By setting the belt assembly, the rotating rods 21 can drive the pulleys 25 and belts 26 to rotate after rotation, thereby providing power for the operation of the compression assembly.

[0041] like Figure 6 As shown, the compression assembly includes rotating plates 27 fixedly installed on the two rotating rods 24 at their respective ends close to each other. A rotating shaft 28 is fixedly installed on the side of the two rotating plates 27 close to each other. An adjusting block 29 is rotatably sleeved on the rotating shaft 28. A piston 30 is hinged to the top of the adjusting block 29. The outer wall of the piston 30 is slidably connected to the inner wall of the compression tank 23. With the compression assembly, the two rotating rods 24 rotate while driving the rotating plates 27 and rotating shaft 28 to rotate. After the rotating plates 27 and rotating shaft 28 rotate, they drive the adjusting block 29 to move. After the adjusting block 29 moves, the piston 30 reciprocates.

[0042] like Figure 6As shown, the gas delivery assembly includes an air inlet pipe 31 fixedly installed on a compression tank 23, a filter 32 fixedly sleeved on the air inlet pipe 31, a fixing rod 33 fixedly installed on the inner top wall of the compression tank 23, a circular plate 34 slidably sleeved on the fixing rod 33, a spring 35 wound around the fixing rod 33, the bottom end of the spring 35 fixedly connected to the circular plate 34, and the top end of the spring 35 fixedly connected to the air inlet pipe 31. An air outlet pipe 36 is fixedly installed on the right side of the compression tank 23, and a fixing rod 37 is fixedly installed on the inner top wall of the compression tank 23, with a circular plate 37 slidably sleeved on the fixing rod 37. 38. A spring 39 is wound around the fixing rod 2 37. The bottom end of the spring 39 is fixedly connected to the circular plate 2 38, and the top end of the spring 39 is fixedly connected to the air outlet pipe 36. With the air delivery assembly, when the piston 30 moves downward, it creates a negative pressure inside the compression tank 23. This pressure difference causes the circular plate 1 34 to open, thereby drawing outside air into the compression tank 23. When the piston 30 moves upward, it compresses the gas inside the compression tank 23, causing the gas pressure to increase. The increase in gas pressure causes the circular plate 2 38 to open, thereby delivering the compressed gas to the spray gun 41 through the air outlet pipe 36.

[0043] like Figure 1 and Figure 7 As shown, the spraying mechanism includes an adjustment component, an anti-clogging component, and a cleaning component. The adjustment component includes a support bar 40 fixedly installed on the top of the base 1. A spray nozzle 41 is hinged to the top of the support bar 40. The front of the spray nozzle 41 is fixedly connected to the air outlet pipe 36. An adapter bar 42 is fixedly installed on the top of the base 1. A slider 43 is slidably installed inside the adapter bar 42. A connecting block 44 is slidably installed on the top of the slider 43. The top of the connecting block 44 is fixedly connected to the spray nozzle 41. A turntable 48 is fixedly sleeved on the rotating rod 24. A sliding rod 49 is fixedly installed on the front of the turntable 48. A rectangular strip 50 is slidably sleeved on the slide rod 49. A control rod 51 is fixedly installed on the back of the rectangular strip 50. The end of the control rod 51 is fixedly connected to the slider 43. By setting an adjustment component, the rotation of the rotating rod 24 causes the turntable 48 to rotate. After the turntable 48 rotates, it drives the control rod 51 to move up and down, thereby driving the slider 43 to move. By moving the slider 43 up and down, the angle of the spraying cylinder 41 can be adjusted, which can ensure that the coating is evenly distributed on the surface of the silicon carbide product, avoid uneven coating, and improve the uniformity and coverage of the coating.

[0044] like Figure 7As shown, the anti-clogging component includes two sealing plates 45 hinged to the inner wall of the spray cylinder 41. A spring 46 is fixedly mounted on the front of each sealing plate 45, and the end of the spring 46 is fixedly connected to the inner wall of the spray cylinder 41. A hinge strip 47 is hinged to the side of the two sealing plates 45 that is close to each other. With the anti-clogging component, when compressed gas blows onto the sealing plates 45, the spring 46 experiences a thrust, causing the two sealing plates 45 to rotate around the hinge point. After the two 45s rotate, compressed air is blown onto the paint. When the spraying device is not in use, the gas supply stops, and the thrust on the spring 46 disappears. The spring 46 then moves the sealing plates 45 back to their original positions, ensuring that the spray cylinder 41 remains sealed when the device is not in use. This prevents the paint from solidifying inside the spray cylinder 41, avoiding clogging and preventing nozzle clogging from affecting the uniformity and accuracy of the spraying, thus improving the uniformity and accuracy of the spraying device.

[0045] like Figure 2 , Figure 7 and Figure 8 As shown, the cleaning assembly includes a flexible hose 52 fixedly installed on the outer wall of the spray cylinder 41, a storage cylinder 53 fixedly installed at the top of the flexible hose 52, a conical block 54 fixedly sleeved on the outer wall of the connecting frame 8, a scraper 55 slidably installed on the inner wall of the storage cylinder 53, and a sliding rod 56 slidably installed on the top of the storage cylinder 53. The end of the sliding rod 56 extends into the storage cylinder 53 and is fixedly connected to the scraper 55, and the top of the sliding rod 56 extends into the conical block 54 and is slidably connected to the conical block 54. With this cleaning assembly, after paint is poured into the storage cylinder 53, the paint inside the storage cylinder 53 will adhere to the inner wall of the storage cylinder 53. The paint adsorbed on the inner wall of the storage cylinder 53 needs to be cleaned. The motor 4 drives the rotating rod 7 to rotate, simultaneously driving the connecting frame 8 to rotate. The rotation of the connecting frame 8 then drives the conical block 54 to rotate. The cone block 54 rotates, and its design features one side higher than the other. When the cone block 54 rotates, its higher side slides against the slide bar 56, causing the slide bar 56 to move downwards. Conversely, when its lower side slides against the slide bar 56, it causes the slide bar 56 to move upwards. This movement of the slide bar 56 and the scraper 55 causes them to rise or fall. The slide bar 56's vertical movement causes the scraper 55 to scrape and clean the paint adsorbed on the inner wall of the storage cylinder 53, thus preventing paint from adsorbing onto the inner wall of the storage cylinder 53. Preventing paint adsorption on the inner wall of the storage cylinder minimizes paint waste, ensuring more paint is used effectively, thereby improving paint utilization and further enhancing the coating effect and quality of the device.

[0046] A specific application of this embodiment is as follows: When the device is needed to coat a workpiece, the motor 4 is started. The motor 4 drives the rotating rod 7 to rotate, which in turn drives the connecting frame 8 to rotate. Several gears 11 mesh with gear 9. Under the effect of the rotation of the connecting frame 8, several cylindrical cylinders 10 are rotated. The rotation of the cylindrical cylinders 10 causes the silicon carbide product to rotate during coating. At the same time as the cylindrical cylinders 10 rotate, the sliding rod 12 moves. Due to the design of the tapered top plate 2 being thin on one side and thick on the other, when the sliding rod 12 touches the thin side of the tapered top plate 2, the force on the spring 17 is released, thereby causing the sliding rod 12 to drive several movable strips 15 to move. After the movable strips 15 move, the workpiece to be coated can be placed inside the cylindrical cylinder. On the 10th, driven by the motor 4, the slide bar 12 moves to the thicker side of the conical top plate 2, causing the slide bar 12 to move downwards. After the slide bar 12 moves downwards, several movable strips 15 open, thereby limiting the bottom of the workpiece. After the rotating rod 7 rotates, it drives the rotating rod 21 to rotate through two bevel gears 22. The rotating rod 21 drives the rotating rod 3 24 to rotate through the pulley 25 and belt 26. The rotation of the rotating rod 3 24 drives the turntable 48 to rotate. After the turntable 48 rotates, it drives the control rod 51 to move up and down, thereby driving the slider 43 to move. By moving the slider 43 up and down, the angle of the spray gun 41 can be adjusted. While the two rotating rods 3 24 are rotating, they also drive the rotating plate 27 and the rotating shaft 2 28 to rotate. After plate 27 and shaft 28 rotate, they drive adjusting block 29 to move. Adjusting block 29 then causes piston 30 to reciprocate. When piston 30 moves downwards, it creates a negative pressure inside compression tank 23. This pressure difference causes circular plate 34 to open, drawing outside air into compression tank 23. When piston 30 moves upwards, it compresses the gas inside compression tank 23, increasing the gas pressure. This increased pressure causes circular plate 38 to open, allowing the compressed gas to be delivered to spray nozzle 41 through outlet pipe 36. When compressed gas blows onto sealing plate 45, spring 46 experiences a thrust, causing the two sealing plates 45 to flip around the hinge. After flipping, the compressed air is blown onto the paint. When the spraying device does not require... When in use, the gas supply stops, thus the thrust on spring 46 disappears. Spring 46 then moves sealing plate 45 back to its original position, ensuring that the spray tube 41 remains sealed when not in use. This prevents the paint from solidifying inside the spray tube 41 and avoids clogging. Simultaneously, the rotating rod 7 rotates, causing the connecting frame 8 to rotate. The rotating frame 8 then rotates the conical block 54. The conical block 54 has a design where one side is higher than the other. When the conical block 54 rotates, it slides against the sliding rod 56, causing the sliding rod 56 to move downwards. Conversely, when the conical block 54 slides against the sliding rod 56, it moves the sliding rod 56 upwards.This allows the slide bar 56 and scraper 55 to rise or fall. The slide bar 56's up-and-down movement drives the scraper 55 to scrape and clean the paint adsorbed on the inner wall of the storage cylinder 53. This prevents paint from adsorbing onto the inner wall of the storage cylinder 53, minimizing paint waste and ensuring more paint is used effectively, thus improving paint utilization.
