Description

Technical Field

[0001] This invention relates to the field of glass spraying technology, and more particularly to an AG glass spraying device. Background Technology

[0002] During the production of AG glass, a thin layer of paint is sprayed onto the surface. During spraying, the mist-like paint is sprayed out through the nozzle and evenly distributed on the glass surface to form a paint film. However, the sprayed mist-like paint is easy to adhere to the nozzle. If it is not cleaned in time, many mist-like paints are easy to aggregate into liquid and drip onto the glass surface, forming paint marks and affecting the uniformity of the paint surface of the glass. To address the above issues, we propose an AG glass spraying equipment. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides an AG glass spraying device that uses air pressure to push a cleaning brush mechanism into the nozzle. After entering the nozzle, the brush rotates to clean the inside of the nozzle, preventing paint mist from coalescing and dripping, thereby ensuring the quality of the spraying.

[0004] The present invention provides an AG glass spraying device, including a conveying mechanism and a protective cover. The protective cover is U-shaped and is installed on the conveying mechanism. A spraying mechanism is provided inside the protective cover. The spraying mechanism includes a fixed frame and a spray head. The fixed frame is fixedly connected to the inside of the protective cover. A sliding frame is slidably connected to the fixed frame. A top rod is fixedly connected to the sliding frame. The spray head is elastically slidably connected to the sliding frame. A horizontal push rod is fixedly connected to the spray head. A vertical stop rod is fixedly connected to the fixed frame. The vertical stop rod is located on the moving path of the horizontal push rod. When the horizontal push rod contacts the vertical stop rod, the spray head no longer moves with the sliding frame.

[0005] A further improvement of the present invention includes a cleaning mechanism inside the protective cover. The cleaning mechanism includes an elastic telescopic rod and a fixed cylinder. The fixed end of the elastic telescopic rod is fixedly connected to the fixed frame, and the extended end is opposite to the top rod. Magnets are fixedly connected to the extended end of the elastic telescopic rod and the end of the top rod, respectively. The two magnets are arranged oppositely. The fixed cylinder is fixedly connected to the protective cover and communicates with the fixed end of the elastic telescopic rod. A cleaning brush mechanism is connected to the piston on the fixed cylinder. The cleaning brush mechanism includes a piston plate, a cleaning brush rod, and a wind plate. The piston plate is sealed and movably connected inside the fixed cylinder. The cleaning brush rod is rotatably connected to the upper surface of the piston plate. The wind plate is fixedly connected to the surface of the cleaning brush rod. A U-shaped tube is connected to the surface of the fixed cylinder. Both ends of the U-shaped tube are located above the piston plate. A one-way valve is installed inside the U-shaped tube. An exhaust pipe is connected to the fixed cylinder and is located on one side above the piston plate. The elastic telescopic rod is compressed and inflated by the sliding frame. The air pressure pushes the cleaning brush rod upward into the nozzle and rotates after entering the nozzle to clean the nozzle.

[0006] Beneficial effects of the present invention: The present invention provides an AG glass spraying device: 1. The nozzle is elastically slidably connected to the sliding frame, ensuring that the nozzle and the cleaning brush mechanism can be aligned on the upper and lower central axes when the sliding frame continues to move in the direction of the elastic telescopic rod, so that the cleaning brush mechanism can extend into the nozzle. 2. By converting the translational motion of the sliding frame into changes in air pressure inside the elastic telescopic rod, the cleaning brush mechanism is pushed to extend into the nozzle and then stops moving upward. The cleaning brush mechanism continues to rotate through the changes in air pressure inside the elastic telescopic rod to clean the inside of the nozzle. Third, the nozzle is elastically slidably connected to the sliding frame, ensuring that the cleaning brush mechanism can come out from inside the nozzle when the sliding frame moves away from the elastic telescopic rod, thus avoiding jamming.

However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Similarly, these embodiments are provided so that the disclosure of the present invention may be more thorough and complete.

[0010] according to Figures 1-8 The AG glass spraying equipment shown includes a conveying mechanism 1 and a protective cover 2. The protective cover 2 is U-shaped and is installed on the conveying mechanism 1. A spraying mechanism 3 is installed inside the protective cover 2. The spraying mechanism 3 includes a fixed frame 5 and a nozzle 6. The fixed frame 5 is fixedly connected to the inside of the protective cover 2. A sliding frame 7 is slidably connected to the fixed frame 5. A top rod 8 is fixedly connected to the sliding frame 7. The nozzle 6 is elastically slidably connected to the sliding frame 7. The specific elastic sliding connection is as follows: a key bar 20 is fixedly connected to the sliding frame 7. The nozzle 6 is axially slidably connected to the key bar 20. A compression spring 21 is sleeved on the key bar 20. The compression spring 21 is in a compressed state, and the compression spring 21 has two... The nozzle 6 and the sliding frame 7 are connected to the end of the protective cover 2 respectively. A drive motor 22 is fixedly connected to the protective cover 2. A threaded rod is fixedly connected to the output end of the drive motor 22. The threaded rod is rotatably connected to the U-shaped cover 2 and the fixed frame 5. The sliding frame 7 is threadedly connected to the threaded rod. When the drive motor 22 starts, it drives the threaded rod to rotate. The sliding frame 7, which is threadedly connected to the threaded rod, moves horizontally when the threaded rod rotates, which drives the sliding frame 7 and the nozzle 6 to move horizontally. A horizontal push rod 12 is fixedly connected to the nozzle 6. A vertical stop rod 13 is fixedly connected to the fixed frame 5. The vertical stop rod 13 is located on the moving path of the horizontal push rod 12. When the horizontal push rod 12 contacts the vertical stop rod 13, the nozzle 6 no longer moves with the sliding frame 7.

[0011] The protective cover 2 is equipped with a cleaning mechanism 4, which includes an elastic telescopic rod 9 and a fixed cylinder 10. The fixed end of the elastic telescopic rod 9 is fixedly connected to the fixed frame 5, and the extended end is opposite to the top rod 8. The extended end of the elastic telescopic rod 9 and the end of the top rod 8 are respectively fixedly connected to magnets 19. The two magnets 19 are arranged opposite to each other. The fixed cylinder 10 is fixedly connected to the protective cover 2. The fixed end of the elastic telescopic rod 9 is fixedly connected to an air guide pipe 23. The other end of the air guide pipe 23 is connected to the fixed cylinder 10. The connection between the air guide pipe 23 and the fixed cylinder 10 is located below the bottom end of the cleaning brush mechanism 11.

[0012] A cleaning brush mechanism 11 is connected to a piston on the fixed cylinder 10. The cleaning brush mechanism 11 includes a piston plate 16, a cleaning brush rod 17, and a wind plate 18. The piston plate 16 is sealed and movably connected inside the fixed cylinder 10. The piston plate 16 is located above the connection between the air guide pipe 23 and the fixed cylinder 10. The cleaning brush rod 17 is rotatably connected to the upper end face of the piston plate 16. The wind plate 18 is fixedly connected to the surface of the cleaning brush rod 17. A U-shaped tube 14 is connected to the surface of the fixed cylinder 10. The two ends of the U-shaped tube 14 are located on the upper and lower sides of the piston plate 16. A one-way valve is provided inside the U-shaped tube 14. An exhaust pipe 15 is connected to the fixed cylinder 10. The exhaust pipe 15 is located on one side above the piston plate 16. The elastic telescopic rod 9 is compressed and inflated by the sliding frame 7. The air pressure pushes the cleaning brush rod 17 to move upward into the nozzle 6 and rotates after entering the nozzle 6 to clean the nozzle 6.

[0013] principle: Spraying: The glass is conveyed to the area below the spray head 6 by the conveying mechanism 1. The drive motor 22 is started, which drives the threaded rod to rotate. This causes the sliding frame 7, which is threadedly connected to the threaded rod, to move horizontally. The moving sliding frame 7 drives the spray head 6 to move horizontally, and the spray head 6 sprays mist paint onto the glass surface, achieving uniform spraying of the glass surface.

[0014] Cleaning: The sliding frame 7 moves the nozzle 6 and the push rod 8 horizontally. When the magnet 19 on the push rod 8 contacts the magnet 19 at the extended end of the elastic telescopic rod 9, the push rod 8 presses the extended end of the elastic telescopic rod 9 towards the fixed end of the elastic telescopic rod 9. This causes the gas inside the fixed end of the elastic telescopic rod 9 to enter the fixed cylinder 10 through the air guide tube 23, pressing the piston plate 16 upward. The upward-moving piston plate 16 drives the cleaning brush rod 17 upward. Before the cleaning brush rod 17 enters the nozzle 6, the vertical stop rod 13 blocks the horizontal push rod 12. At this time, the central axis of the nozzle 6 and the central axis of the cleaning brush rod 17 are on the same vertical line. The sliding frame 7 continues to move horizontally, while the nozzle 6 stops moving horizontally. The sliding frame 7 continues to push the piston plate 16 upward in the above manner, so that the cleaning brush rod 17 penetrates into the nozzle 6. The piston plate 16 moves until it is no longer completely below the lower end of the U-shaped tube 14. At this time, the air plate 18 is located at the upper end of the U-shaped tube 14. As the sliding frame 7 continues to move horizontally, the air pressure inside the fixed cylinder 10 and below the piston plate 16 enters above the piston plate 16 through the U-shaped tube 14 and is discharged from the exhaust pipe 15. During the air pressure flow, the air pressure pushes the air plate 18 to rotate, and the air plate 18 drives the cleaning brush rod 17 to rotate, cleaning the inside of the nozzle 6.

[0015] When the threaded rod drives the sliding frame 7 to move away from the elastic telescopic rod 9, the push rod 8 follows the sliding frame 7 to move away from the elastic telescopic rod 9. Due to the action of the two magnets 19 and the elastic recovery performance of the elastic telescopic rod 9 itself, the push rod 8 pulls the extended end of the elastic telescopic rod 9 to move, and the extended end of the elastic telescopic rod 9 returns to its original position and extends out, resulting in negative pressure inside the fixed end of the elastic telescopic rod 9, which causes the piston plate 16 to move downward, and the cleaning brush rod 17 to come out from inside the nozzle 6 and return to its original position.

[0016] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be defined by the claims.
