Description

Technical Field

[0001] This utility model relates to the field of spraying technology, specifically to a device for uniform surface spraying in evaporator production. Background Technology

[0002] An evaporator is a device that converts a liquid substance into a gaseous state, primarily through heat transfer to achieve a phase change process. In a refrigeration system, the evaporator is one of the four main components. Low-temperature condensed liquid exchanges heat with the outside air through the evaporator, vaporizing and absorbing heat, thereby achieving a cooling effect.

[0003] To enhance the corrosion resistance and aesthetics of the evaporator, its surface needs to be sprayed during the production process. Generally, the evaporator is first fixed and one side is sprayed, then it is unfixed, flipped over, and fixed again to spray the other side. This method is time-consuming and labor-intensive, affecting work efficiency.

[0004] Therefore, we have made improvements to this and proposed a surface uniform spraying device for evaporator production. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example: Figures 1 to 4 As shown, this utility model discloses a surface uniform spraying device for evaporator production, comprising a base plate 1, with side plates 2 symmetrically fixed on both sides of the top surface of the base plate 1. A rotating shaft 12 is rotatably mounted on each of the two side plates 2, and a placement frame 10 is fixedly mounted between the rotating shafts 12. A motor 13 is mounted on one of the side plates 2; the motor 13 is a geared motor, and one end of one of the rotating shafts 12 rotatably passes through the side plate 2 and is fixedly connected to the output end of the motor 13. When the motor 13 operates, it drives the rotating shaft 12 connected to it to rotate. The rotation of the rotating shaft 12 drives the placement frame 10 to rotate, thereby flipping the placement frame 10, which in turn flips the evaporator body 14 inside, facilitating the spraying of the surface of the evaporator body 14.

[0023] The placement frame 10 is vertically continuous, and the evaporator body 14 is placed inside the placement frame 10. The top and bottom surfaces of the placement frame 10 are respectively fitted with cover plates 8. When the top surface of the evaporator body 14 is sprayed, the top cover plate 8 does not cover it, and the bottom cover plate 8 supports the evaporator body 14. When it needs to be flipped, the top cover plate 8 needs to cover the placement frame 10.

[0024] Connecting plates 9 are fixedly installed at both ends of the cover plate 8, and one end of the connecting plate 9 is rotatably mounted on the side plate 2. An electric push rod 18 is fixedly installed between the opposite surfaces of the connecting plates 9. When the cover plate 8 needs to be moved to cover the placement frame 10, or not to cover it, it is achieved by the electric push rod 18. The electric push rod 18 is a dual-axis electric push rod, and the two axes are respectively connected to the upper and lower connecting plates 9.

[0025] Linear guide rails 3 are fixedly installed on both sides of the side plate 2. A slider 4 is slidably mounted on the linear guide rail 3, and an electric push rod 5 is fixedly mounted on the slider 4. The telescopic ends of the electric push rod 5 on the same side are fixedly mounted with a connecting frame 6, and multiple spray pipes 7 are mounted on the connecting frame 6. When the slider 4 moves on the linear guide rail 3, it can drive the electric push rod 5 and the connecting frame 6 to move, thereby driving the spray pipes 7 to move. When it is necessary to adjust the cover plate 8 and the placement frame 10 to be flipped, the slider 4 moves to the bottom of the placement frame 10. At the same time, the electric push rod 5 drives the connecting frame 6 to move away from the placement frame 10 to prevent it from affecting the flipping of the placement frame 10. After the placement frame 10 is flipped, the slider 4 moves upward, and at the same time, the electric push rod 5 drives the connecting frame 6 to move, so that the spray pipes 7 can spray the evaporator body 14. It should be noted that before flipping, the paint needs to be dried first to avoid affecting the spraying effect.

[0026] The placement frame 10 has through slots 11 extending through both the front and back, and the width of the through slots 11 is smaller than the width of the evaporator body 14. The through slots 11 facilitate the spraying of the sides of the evaporator body 14 by the spraying pipe 7, and any unsprayed areas can be touched up later by other methods as needed.

[0027] The opposite surfaces of the side plate 2 are respectively provided with arc-shaped grooves 15, and the top and bottom surfaces of the arc-shaped grooves 15 are respectively connected to square grooves 16. A movable block 17 is slidably disposed in the arc-shaped groove 15. The movable block 17 is fixedly connected to the connecting plate 9, and the movable block 17 is also slidably connected to the square groove 16. When the rotating shaft 12 drives the placement frame 10 to flip, the placement frame 10 drives the other snap-fit ​​cover plates 8 to flip, thereby driving the connecting plate 9 to flip together through the cover plates 8. The connecting plate 9 drives the movable block 17 to move in the arc-shaped groove 15. After the flip is completed, the movable block 17 is at the connection between the square groove 16 and the arc-shaped groove 15, so that the movable block 17 can slide along the square groove 16 when the connecting plate 9 moves upward.

[0028] A telescopic pipe is installed at the bottom of the connecting frame 6. The spray pipe 7 is L-shaped. Spray nozzles (not shown in the figure) are installed at the horizontal and vertical ends of the spray pipe 7. The bottom end of the telescopic pipe is connected to the existing painting equipment (such as a paint pump and a paint supply box connected to the paint pump). A connecting pipe (not shown in the figure) is installed inside the connecting frame 6. Multiple spray pipes 7 are connected to the connecting pipe, and the connecting pipe is connected to the telescopic pipe, so as to facilitate spraying through the spray pipe 7.

[0029] During operation, when it is necessary to flip the evaporator body 14, the cover plate 8 can be moved by the electric push rod 18 to cover the placement frame 10. Then, under the action of the motor 13, the rotating shaft 12 is rotated, thereby rotating the placement frame 10 and flipping the evaporator body 14. After flipping, the electric push rod 18 moves the cover plate 8 located at the top, so that the spray pipe 7 can spray the evaporator body 14. This method can effectively improve the spraying efficiency.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
