DETAILED DESCRIPTION

[0027] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0028] The present invention will be described in detail below with reference to the accompanying drawings. This embodiment discloses a paint spraying and drying device for automobile leaf springs. Figure 1As shown, it includes a base 1, a second motor 17 is provided at the lower end of the base 1, the output end of the second motor 17 is connected to the rotating shaft 2, one end of the rotating shaft 2 is connected to the disc 3, and a plurality of supporting devices 4 are provided on the disc 3; a U-shaped plate 6 is provided at the upper end of the base 1, through holes are provided at both ends of the upper surface of the U-shaped plate 6, and tubes 7 are provided in the through holes at both ends. The upper part of the tube 7 at one end is connected to the first L-shaped tube 14, and the upper part of the tube 7 at the other end is connected to the second L-shaped tube 16, and the lower parts of the tubes 7 at both ends are connected to the U-shaped spray pipe 8; the U-shaped spray pipe 8 is above the supporting device 4;

[0029] One end of the upper surface of the U-shaped plate 6 is fixedly connected to the pump body 12, the input end of the pump body 12 is fixedly connected to the paint tube 13, and the output end of the pump body 12 is fixedly connected to the first L-shaped tube 14; the other end of the upper surface of the U-shaped plate 6 is fixedly connected to the hot air blower 15, and the output end of the hot air blower 15 is connected to the second L-shaped tube 16; a driving mechanism is set in the middle of the upper surface of the U-shaped plate 6.

[0030] The paint tube 13 can be connected to an external paint bucket. Once connected, the pump body 12 is activated, pumping paint into the corresponding U-shaped spray tube 8, thereby painting the leaf spring 5. The hot air blower 15 can input hot air into the U-shaped spray tube 8 to dry the leaf spring 5. During use, multiple leaf springs 5 are placed on corresponding support devices 4. The U-shaped spray tube 8 is then rotated to evenly spray paint on the surface of each leaf spring 5. The disc 3 is then rotated to spray hot air through another U-shaped spray tube 8 to dry the leaf springs 5.

[0031] The rotating shaft 2 passes through the base 1 and is fixedly connected to the disc 3. The rotating shaft 2 and the base 1 are movably connected. The disc 3 is fixedly connected to the support device 4, and a plurality of leaf springs 5 are placed on the support device 4. The rotation of the disc 3 is achieved by the cooperation of the second motor 17 and the rotating shaft 2. The second motor 17 is movably connected to the base 1. When the second motor 17 is started, it drives the rotating shaft 2 to rotate. The rotation of the rotating shaft 2 drives the rotating disc 3 to rotate, and in turn drives the support device 4 above the disc 3 to rotate. The rotation of the disc 3 realizes the switching of the position of the support device 4. After the leaf spring 5 on one support device 4 is painted, the disc 3 rotates to drive the support device 4 with the painted leaf spring 5 to the drying position, and the support device 4 with the unpainted leaf spring 5 is moved to the painting position. This allows the painting and drying work to be carried out simultaneously, and the leaf springs 5 in different states can be processed, thereby improving overall work efficiency.

[0032] A plurality of nozzles 81 are spaced apart on the inside of the U-shaped spray pipe 8, and are distributed on the upper portion and on both sides of the support device 4. The nozzles 81 are spaced apart on the U-shaped pipe to ensure that the paint is evenly sprayed on the surface of the leaf spring 5 and that the hot air from the hot air blower 15 is blown from multiple directions onto the painted leaf spring 5, allowing the painted leaf spring 5 to dry quickly.

[0033] The drive mechanism includes a first motor 9, a driving gear 10, and a driven gear 11. The first motor 9 is fixedly connected to the U-shaped plate 6. The output end of the first motor 9 passes through the U-shaped plate 6 and is connected to the driving gear 10. Driven gears 11 are set at both ends of the driving gear 10, and the driven gears 11 at both ends are engaged with the driving gear 10. The driven gear 11 is sleeved on the tube body 7 and is fixedly connected to the tube body 7. The driven gear 11 drives the tube body 7 to rotate. The first motor 9 drives the driving gear 10 to rotate. The rotation of the driving gear 10 drives the driven gears 11 at both ends to rotate, and then drives the tube body 7 to rotate. The tube body 7 is fixedly connected to the U-shaped spray pipe 8, and then drives the U-shaped spray pipe 8 to rotate, so that the paint or hot air is evenly sprayed on the leaf spring 5.

[0034] A plurality of support bases 18 are symmetrically arranged at the lower end of the base 1, and the support bases 18 are fixedly connected to the base 1. The base 1 is supported by the support bases 18, and a plurality of support bases are arranged to ensure the stability of the support, and the base 1 is raised so that there is space under the base 1 for installing the second motor 17.

[0035] like Figure 3 As shown, the support device 4 includes a support frame 41 and a placement beam 42. A plurality of placement beams 42 are spaced apart at both ends of the support frame 41. The placement beams 42 are arranged from top to bottom on the support frame 41 and are used to support both ends of the leaf spring 5. Providing multiple placement beams 42 allows multiple leaf springs 5 to be placed vertically and spaced apart, allowing multiple leaf springs 5 to be painted or dried simultaneously, improving work efficiency.

[0036] like Figure 2 As shown, the first L-shaped tube 14 is connected to the tube body 7 at one end, and the second L-shaped tube 16 is connected to the tube body 7 at the other end. The tube body 7 is connected to the U-shaped spray pipe 8. The paint pipe 13 is connected to the pump body 12, and the pump body 12 is connected to the first L-shaped tube 14. The hot air blower 15 is connected to the second L-shaped tube 16. The paint pipe 13 connects the pump body 12 to the paint bucket. The pump body 12 pumps the paint to the corresponding tube body 7, and then flows into the corresponding U-shaped spray pipe 8, so that the paint is sprayed on the leaf spring 5. Hot air is generated by the hot air blower 15, and the hot air is blown to the corresponding tube body 7, and then enters the corresponding U-shaped spray pipe 8, so that the hot air is blown to the painted leaf spring 5, so that the leaf spring 5 is quickly dried; the diameter of the nozzle 81 provided on the U-shaped spray pipe 8 connected to the hot air blower 15 can be larger than the diameter of the nozzle 81 provided on the U-shaped spray pipe 8 connected to the pump body 12, thereby facilitating the blowing of hot air onto the painted leaf spring 5; the first L-shaped tube 14 and the second L-shaped tube 16 are both rotatably connected to the corresponding tube body 7, and the tube body 7 will not drive the first L-shaped tube 14 and the second L-shaped tube 16 to rotate when it rotates.

[0037] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
