Description

Technical Field

[0001] This utility model relates to the field of glass processing equipment technology, and in particular to a glass powder spraying device for automotive glass production. Background Technology

[0002] During the manufacturing of automotive laminated glass, a thin layer of powder is sprayed onto the glass surface to prevent the two pieces of glass from sticking together during the bending process. This powder-coated glass can be separated more smoothly in subsequent processing, reducing operational difficulties and improving production efficiency.

[0003] When powder coating glass, the glass moves at a constant speed on a conveyor mechanism, and the powder coating equipment treats the glass surface. For example, Chinese utility model patent CN210765009U discloses a powder coating device for automotive laminated glass production. This application encloses the powder coating work area by setting up a box to prevent the floating and diffusion of seaweed powder from affecting other equipment and personnel during the production process. By setting up a conveyor component in the box to convey the automotive glass, continuous powder coating is achieved, improving production efficiency. However, when powder coating automotive glass, different thicknesses of glass require different powder coating distances to ensure that the coating can be evenly covered on the glass surface. If the height of the powder coating mechanism is fixed, the coating may be too thick or too thin, affecting the coating quality. However, in this application, since the spray nozzle is suspended by vertical rods and nuts, adjusting the height of the spray nozzle requires adjusting multiple nuts that fix the vertical rods. Moreover, it is not convenient for a single person to easily rotate the nuts on the two vertical rods, which brings certain inconvenience to the adjustment process of the spray nozzle height.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-4As shown, the present invention provides a glass powder coating device for automotive glass production, including a conveyor 1, a plurality of side plates 2 fixedly installed on the conveyor 1, a powder coating mechanism 3 arranged between the plurality of side plates 2, the powder coating mechanism 3 including a splash guard 4, a lifting cover 6 movably installed inside the splash guard 4, a plurality of connecting rods 5 fixedly installed on the top of the lifting cover 6, and a mounting beam 7 fixedly connected between two connecting rods 5, and one side of each of the two mounting beams 7 movably connected to one side of the corresponding two side plates 2, and a first connecting plate 8 fixedly connected between the two mounting beams 7, an adjusting screw 9 movably installed on the top of the first connecting plate 8, and a rotating handle 10 movably installed in the first connecting plate 8 located inside the adjusting screw 9.

[0022] like Figures 1-2 As shown, a guide rail 11 is fixedly installed on one side of the side plate 2, and a slider 12 is slidably installed on the guide rail 11. A second connecting plate 14 is fixedly connected between the two side plates 2, and a third connecting plate 15 is fixedly connected between the two second connecting plates 14. A screw hole is opened in the center of the third connecting plate 15. The arrangement of the second connecting plate 14 and the third connecting plate 15 can provide a fulcrum for the rotation of the adjusting screw 9 and provide conditions for the lifting and lowering of the first connecting plate 8. Two first supports 13 are fixedly installed on one side of the mounting beam 7. A second support 16 is also fixedly installed on the mounting beam 7 between the two first supports 13. The two first supports 13 are respectively fixedly installed on one side of the corresponding slider 12. Multiple powder spraying heads 27 are fixedly installed at the bottom of the mounting beam 7. The multiple powder spraying heads 27 are connected to the output end of the external conveying device through the pipe inside the mounting beam 7.

[0023] like Figures 3-4 As shown, the first connecting plate 8 is fixedly installed between the two second supports 16. A first fixed seat 17 is fixedly installed on the top of the first connecting plate 8, and a second fixed seat 18 is fixedly installed on the top of the first fixed seat 17. A first rotating groove 19 is formed in the first fixed seat 17, and multiple toothed grooves 20 are formed in the top of the first rotating groove 19. A second rotating groove 21 is formed in the second fixed seat 18. The rotating handle 10 has a regular hexagonal cross-section. A toothed disc 24 is fixedly installed at the bottom of the rotating handle 10. The toothed disc 24 is rotatably installed in the first rotating groove 19. A compression spring is also placed in the first rotating groove 19 at the bottom of the toothed disc 24. An operating handle is fixedly installed on the top of the rotating handle 10. 25. A rotating block 22 is fixedly installed at the bottom of the adjusting screw 9. An insertion hole 23 is opened in the adjusting screw 9. The transverse cross section of the insertion hole 23 is a regular hexagon. The bottom of the adjusting screw 9 is rotatably installed in the second rotating groove 21 through the rotating block 22. The outer side of the adjusting screw 9 is also threadedly connected to the screw hole in the third connecting plate 15. The insertion hole 23 is inserted and installed on the outer side of the rotating handle 10. The adjusting screw 9 can be rotated through the rotating handle 10, so that the adjusting screw 9 rotates in the screw hole of the third connecting plate 15 to adjust the height of the first connecting plate 8. Under normal circumstances, the top of the gear plate 24 is engaged with multiple tooth grooves 20, which can cooperate with the rotating handle 10 to restrict the rotation of the adjusting screw 9.

[0024] It should be noted that this utility model is a glass powder coating device for automotive glass production. When coating glass with powder, the glass can be placed on the conveyor 1, and then the conveyor 1 will uniformly transport the glass to the position below the powder coating mechanism 3. This, in conjunction with the external powder conveying equipment, will deliver powder to multiple powder coating heads 27, ensuring that the powder is evenly coated on the glass surface. When the coating height needs to be adjusted according to production requirements, the operating handle 25 can be held directly and the rotating handle 10 can be pressed down. The rotating handle 10 will then drive the toothed disc 24 to move down in the first rotating groove 19. At the same time, the toothed disc 24 will compress the compression spring in the first rotating groove 19 towards the bottom of the first rotating groove 19, thereby causing the top of the toothed disc 24 to disengage from the multiple toothed grooves 20 at the top of the first rotating groove 19. Then, the rotating handle 10 can be rotated by the operating handle 25, which will drive the adjusting screw 9 to rotate through the insertion hole 23. As a result, the rotating block 22 at the bottom of the adjusting screw 9 will rotate in the second rotating groove 21. Meanwhile, the adjusting screw 9 rotates in the screw hole in the third connecting plate 15, thereby adjusting the height of the first connecting plate 8. Thus, the first connecting plate 8 adjusts the height of the two mounting beams 7 synchronously through the two second supports 16, and the two mounting beams 7 slide up and down on the corresponding two guide rails 11 through the two first supports 13 and sliders 12 on one side. Thus, the height of the lifting cover 6 and multiple powder spraying heads 27 is adjusted through the mounting beams 7 and connecting rod 5. At the same time, the lifting cover 6 also moves up and down in the splash guard 4 through the sealing gaskets 26 on both sides, thereby conveniently adjusting the spraying height of multiple powder spraying heads 27. After the adjustment is completed, the operating handle 25 is released, and the toothed disc 24 is pushed up by the elastic force of the compression spring in the first rotating groove 19. Thus, the top of the toothed disc 24 is re-engaged into the multiple tooth grooves 20, which restricts the rotation of the toothed disc 24 and the rotating handle 10. Thus, the rotation of the adjusting screw 9 is restricted by the rotating handle 10, thereby ensuring the stability of the height of the powder spraying head 27.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
