Description

Technical Field

[0001] This utility model relates to a spraying device, and more particularly to a graphene anti-corrosion coating spraying device. Background Technology

[0002] With industrial development, the requirements for the corrosion resistance of materials are becoming increasingly stringent. Graphene anti-corrosion coatings have attracted widespread attention due to their excellent physicochemical properties. Graphene anti-corrosion coatings have demonstrated great potential in improving the corrosion resistance of materials; however, the uniformity and coverage during the spraying process have become key factors restricting their application. Traditional spraying equipment often struggles to meet the spraying needs of workpieces with complex shapes, especially when dealing with workpieces with curved or hemispherical surfaces, where the limitations of ordinary spraying equipment become even more apparent.

[0003] Chinese patent CN220277366U discloses a graphene anti-corrosion coating spraying device, comprising a base, a mounting frame, and a movable seat. Several mounting seats are welded to the lower surface of the movable seat, hydraulic rods are welded to the lower surface of the mounting seats, a lifting plate is welded to the lower surface of the hydraulic rods, a bracket is welded to the lower surface of the lifting plate, and a spray pipe is mounted on the outer surface of the bracket. The spraying device in this patent can only perform reciprocating spraying operations in the horizontal direction, suitable for spraying workpieces with flat surfaces. However, it is inadequate for spraying complex structures such as hemispherical shells, failing to guarantee the uniformity and integrity of the coating. Utility Model Content

[0004] To overcome the shortcomings of existing spraying equipment in spraying complex structures such as hemispherical shell workpieces, which is inadequate and cannot guarantee the uniformity and integrity of the coating, the technical problem to be solved is to provide a graphene anti-corrosion coating spraying device.

The first motor is mounted on the mounting platform, and the drive gear is connected to the output shaft of the first motor.

[0007] In one embodiment, the walking mechanism includes a second motor and a positioning wheel. The second motor is fixedly mounted on one end of the swing frame, and the positioning wheel contacts the arc-shaped guide rail and is connected to the output shaft of the second motor.

[0008] In one embodiment, the device further includes an arc-shaped rack, a driven gear, a disc, and a slotted connecting plate. The arc-shaped rack is mounted on the inner side of the arc-shaped guide rail. The driven gear, which meshes with the arc-shaped rack, is rotatably connected to the swing frame. The disc is coaxially connected to the driven gear. The slotted connecting plate is connected to the paint spray pipe. A pin is provided at the eccentric position of the disc, and the pin is located in a groove inside the slotted connecting plate.

[0009] In one embodiment, the system further includes an L-shaped positioning rod, an external gear turntable, a shaft gear, and a lifting frame. The lifting frame is slidably disposed below the rotating platform. The L-shaped positioning rod is slidably disposed circumferentially on the lifting frame. The external gear turntable is rotatably connected to the bottom of the rotating platform. The external gear turntable is provided with arc-shaped through grooves circumferentially spaced. The L-shaped positioning rod is located in the arc-shaped through grooves. The top of the rotating platform is provided with clearance holes circumferentially spaced. The upper end of the L-shaped positioning rod passes through the clearance holes. The shaft gear is rotatably mounted on the rotating platform and meshes with the external gear turntable.

Detailed Implementation

[0023] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0024] Example 1: A graphene anti-corrosion coating spraying device, such as Figures 1-6 As shown, the system includes an isolation cover 1, an installation platform 2, an arc-shaped guide rail 3, a swing frame 4, a paint spray pipe 5, a traveling mechanism, and an electric turntable. The installation platform 2 has arc-shaped guide rails 3 on both the front and rear sides of its top. A swing frame 4 is slidably installed between the two arc-shaped guide rails 3. A traveling mechanism is installed on the swing frame 4 to drive the swing frame 4 to move along the arc-shaped guide rails 3. The lower part of the swing frame 4 is rotatably connected to the paint spray pipe 5. The bottom of the paint spray pipe 5 is equipped with nozzles at intervals. An electric turntable is installed on the top of the installation platform 2. The electric turntable is used to place the workpiece to be sprayed. An isolation cover 1 is installed on the outer side of the top of the installation platform 2. The isolation cover 1 is used to prevent paint from splashing or spreading to the surrounding environment during spraying operations, thereby protecting the operating environment and personnel safety. A cover plate 21 is hinged on the isolation cover 1. The cover plate 21 can be opened and closed to facilitate the placement or removal of the workpiece to be sprayed.

[0025] like Figure 3As shown, the electric turntable includes a turntable 6, a first motor 7, and a drive gear 8. The turntable 6 is rotatably connected to the mounting platform 2. The turntable 6 is located in the middle of the mounting platform 2. The outer side of the turntable 6 is evenly spaced with toothed grooves that mesh with the drive gear 8. The first motor 7 is mounted on the mounting platform 2. The outer side of the first motor 7 is provided with a cover fixed to the top of the mounting platform 2 to protect the first motor 7. The drive gear 8 is connected to the output shaft of the first motor 7 through a coupling. The top of the turntable 6 is provided with densely distributed lifting pads 20.

[0026] like Figure 4 As shown, it also includes an arc-shaped rack 11, a driven gear 12, a disc 13, and a slotted connecting plate 14. An arc-shaped groove is opened in the middle of the arc-shaped guide rail 3. Arc-shaped racks 11 are installed on the inner sides of both arc-shaped guide rails 3. Both ends of the swing frame 4 are rotatably connected to driven gears 12 that mesh with the arc-shaped racks 11. The driven gears 12 are located below the arc-shaped racks 11. The disc 13 is coaxially connected to the driven gears 12. The top of both ends of the paint spray pipe 5 are connected to slotted connecting plates 14. A groove is provided in the middle of the slotted connecting plate 14. A pin is provided at the eccentric position of the disc 13. The pin is located in the groove inside the slotted connecting plate 14. When the swing frame 4 moves, the driven gear 12 meshes with the arc-shaped rack 11 to drive the disc 13 to rotate. Under the action of the pin and the slotted connecting plate 14, the paint spray pipe 5 is driven to swing back and forth to ensure the uniformity of the spraying.

[0027] When applying graphene anti-corrosion coating to a workpiece with a hemispherical top, the coating nozzle 5 is connected to the graphene anti-corrosion coating spraying equipment via a hose. The cover plate 21 is opened, and the workpiece is placed on the rotating table 6. The first motor 7 is started to drive the drive gear 8 to rotate. The rotating table 6 rotates under the action of the toothed groove and the drive gear 8, and the workpiece on it is driven to rotate together. At the same time, the second motor 9 is started to drive the positioning wheel 10 to rotate. The positioning wheel 10 drives the swing frame 4 to move along the trajectory of the arc-shaped guide rail 3. The driven gear 12 rotates under the action of the arc-shaped rack 11. The disc 13 follows the driven gear 12 to rotate. Through the pin on it, the slotted connecting plate 14 swings around the center of the coating nozzle 5. The coating nozzle 5 swings back and forth accordingly. A limit switch is set at the end of the arc-shaped guide rail 3. When the swing frame 4 moves and contacts the limit switch, the control system controls the first motor 7 to rotate in the opposite direction, so that the swing frame 4 moves to the other side. In this way, the swing frame 4 can automatically reciprocate. Using the lifting pad 20 to place the workpiece reduces the contact area with the surface of the rotating table 6, thereby reducing paint buildup in the contact area during spraying. This effectively prevents adhesion problems after the paint cures, ensuring that the workpiece can be easily and safely removed after spraying. Even if paint covers both the workpiece and the rotating table 6 simultaneously, they can be quickly separated.

[0028] Example 2; Based on Example 1, such as Figure 5As shown, it also includes L-shaped positioning rods 15, external gear turntables 16, shaft gears 17, and lifting frames 18. The bottom of the rotating platform 6 is provided with guide rods (not shown in the figure). The lifting frame 18 is slidably mounted below the rotating platform 6 via the guide rods. The lifting frame 18 is generally circular, and its bottom is evenly spaced with six guide sleeves (not shown in the figure). Six L-shaped positioning rods 15 are slidably mounted at the bottom of the lifting frame 18 via the guide sleeves. The external gear turntable 16 is rotatably connected to the bottom of the rotating platform 6. The external gear turntable 16... The rotating platform 6 has six arc-shaped through slots spaced apart. The L-shaped positioning rod 15 is located in the arc-shaped through slots. The top of the rotating platform 6 has six clearance holes spaced apart along its circumference. These clearance holes extend from the center of the rotating platform 6 in a direction away from the center. The upper end of the L-shaped positioning rod 15 passes through the clearance holes and is higher than the rotating platform 6. The shaft gear 17 is rotatably mounted on the rotating platform 6 and meshes with the external gear turntable 16. The upper end of the shaft gear 17 extends out of the rotating platform 6 and is connected to a handle.

[0029] like Figure 5 As shown, it also includes a ratchet 22 and an elastic anti-reverse plate 23. The ratchet 22 is provided on the outer side of the upper part of the shaft gear 17. The ratchet 22 is located above the rotating platform 6. The top of the rotating platform 6 is connected to the elastic anti-reverse plate 23, and the elastic anti-reverse plate 23 is in contact with the ratchet 22.

[0030] like Figure 6 As shown, it also includes a screw 19. The screw 19 is rotatably connected to the center of the rotating table 6. The lower part of the screw 19 is threadedly connected to the center of the lifting frame 18. The screw 19 is an internal hexagon screw 19, and its top end is not higher than the top end of the rotating table 6.

[0031] During the spraying process, the workpiece on the rotating table 6 is prone to displacement due to equipment vibration or the centrifugal force of the rotating table 6. Therefore, to prevent the workpiece from moving on the rotating table 6, the workpiece is placed on top of the rotating table 6, positioned between the inner sides of the six L-shaped positioning rods 15. Rotating the shaft gear 17 clockwise drives the external gear turntable 16 to rotate counterclockwise. The elastic anti-reverse plate 23 slides over the back of the ratchet 22 teeth. The external gear turntable 16, through its arc-shaped through groove, drives the six L-shaped positioning rods 15 to move synchronously, causing the L-shaped positioning rods 15 to move towards the workpiece and clamp it. When the shaft gear 17 is not rotating, it elastically abuts against the ratchet 22, preventing the ratchet 22 and shaft gear 17 from rotating counterclockwise and avoiding the L-shaped positioning rods 15 from moving away from the workpiece under the action of centrifugal force. When the shaft gear 17 needs to rotate counterclockwise, the elastic anti-reverse plate 23 is first pried open to allow its elastic deformation to no longer obstruct the ratchet 22, allowing the shaft gear 17 to rotate. When it is necessary to adjust the distance between the workpiece and the paint spray nozzle 5, turn the screw 19 with a hex wrench. The screw 19 drives the lifting frame 18 to move upward, and the L-shaped positioning rod 15 drives the clamped workpiece to move upward, so that it is close to the paint spray nozzle 5. When the position is adjusted to a suitable position, stop turning the screw 19.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
