Detailed Implementation

[0027] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0028] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0029] See Figure 1-6 The multi-nozzle spraying equipment shown includes a base 1, a telescopic frame 2 installed at the rear end of the base 1, and a top plate 3 fixed to the top of the telescopic frame 2. The base 1, telescopic frame 2, and top plate 3 form a U-shaped frame structure. A first servo motor 6 is installed on the top plate 3. A spraying frame is installed at the lower end of the shaft of the first servo motor 6. Multiple telescopic rods 12 that can be radially extended and retracted are arranged circumferentially at the lower end of the spraying frame. A vertical spraying pipe 13 is installed at the outer end of the telescopic rod 12. Multiple spraying heads 15 are arranged vertically on the side of the spraying pipe 13 facing the spraying frame.

[0030] By implementing the above technical solution, in use, the workpiece to be sprayed is placed below the spraying frame. The vertical position of multiple spray heads 15 is adjusted by the telescopic frame 2. After adjustment, paint is supplied to the spraying pipe 13 through the conveying pipe at the upper end of the spraying pipe 13, so that the paint is sprayed out from the multiple spray heads 15. At the same time, the rotation of the first servo motor 6 drives the spraying frame to rotate back and forth, realizing reciprocating spraying of the side of the workpiece. This multi-nozzle spraying equipment can adjust the spraying height position through the telescopic frame 2, and adjust the spraying diameter through the radially sliding telescopic rod 12, thereby enabling adaptive spraying of workpieces with different radii and controlling the distance between the spray head 15 and the surface of the workpiece. Since the height and radial distance are adjustable, the spraying stability can be improved. The telescopic frame 2 in this utility model can be an electric telescopic plate or a hydraulic telescopic plate.

[0031] In this embodiment, to further provide a spraying frame, the spraying frame includes an upper flange plate 5 fixed to the lower end of the shaft of the first servo motor 6. A lower flange plate 7 is connected to the bottom of the upper flange plate 5 by multiple bolts 8. A disc 10 is connected to the lower flange plate 7 by multiple connecting rods 11. The disc 10 has a cavity 19 inside, and multiple sliding holes corresponding one-to-one with the telescopic rod 12 are provided on the side of the disc 10. A drive mechanism capable of driving the telescopic rod 12 to slide within the sliding holes is installed on the disc 10. The detachable connection between the upper flange plate 5 and the lower flange plate 7 facilitates maintenance.

[0032] In this embodiment, to further provide a structure for the drive mechanism, a second servo motor 9 is mounted on the disc 10. The shaft 20 of the second servo motor 9 extends into the cavity 19. The portion of the shaft 20 located within the cavity 19 has multiple circumferentially extending arc-shaped swing arms 17. Each arc-shaped swing arm 17 has an arc-shaped groove 18. The inner end of the telescopic rod 12 has a protrusion 22 that slides within the arc-shaped groove 18. The rotation of the second servo motor 9 causes the protrusion 22 to slide within the arc-shaped groove 18, thereby driving the telescopic rod 12 to reciprocate along the radial direction of the disc 10, thus adjusting the distance between the spray pipe 13 and the center of the disc 10.

[0033] In this embodiment, the arc-shaped swing arm 17 has a socket in its middle for inserting the telescopic rod 12. The left, right, and outer ends of the socket are open, and the arc-shaped groove 18 is located above and below the socket. With this arrangement, one protrusion 22 is located on the upper and lower sides of the telescopic rod 12, and the two protrusions 22 slide within their respective arc-shaped grooves 18, thereby improving overall stability.

[0034] In this embodiment, the outer end of the arc-shaped swing arm 17 is fitted against the side wall of the circular cavity 19. This arrangement makes the arc-shaped swing arm 17 more stable.

[0035] In this embodiment, to further improve the structure of the spray tube 13, an external thread 21 is provided at the upper end of the spray tube 13, and a nut 14 is fitted over the external thread 21. This arrangement enables the spray tube 13 to be detachable, facilitating its installation and replacement.

[0036] In this embodiment, the bottom of the outer end of the telescopic rod 12 is provided with a foolproof limiting groove 23; the upper end of the spraying pipe 13 is provided with a foolproof limiting ring 24 that can fit into the foolproof limiting groove 23. For example, both the foolproof limiting groove 23 and the foolproof limiting ring 24 are regular hexagonal structures, thereby preventing the spraying pipe 13 from rotating during use. The spraying pipe 13 can be as follows: the lower end is the main body, the upper end is the inlet pipe, the delivery pipe is connected to the upper end of the inlet pipe, the external thread 21 is provided at the upper end of the inlet pipe, the foolproof limiting ring 24 is provided at the lower end of the inlet pipe, and the inlet pipe can be inserted into the insertion hole provided at the outer end of the telescopic rod 12.

[0037] In this embodiment, the base 1 has a plurality of supporting protrusions 16 arranged around the axis of the shaft. This arrangement allows the workpiece to be coated to be supported on the supporting protrusions 16, reducing the bottom support contact area and thus improving the coating performance.

[0038] In this embodiment, the bottom surface of the base 1 is provided with multiple support feet 4. The multiple support feet 4 provide better support for the entire structure.

[0039] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0040] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
