Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-4 , a spraying device with a protection structure, including a spraying box 1. At the top inside the spraying box 1, a material guiding bin 2 is fixedly connected. At the bottom of the material guiding bin 2, a spraying nozzle 4 is fixedly connected. At the top of the spraying box 1, a paint pump 3 is fixedly connected. The output end of the paint pump 3 penetrates the top of the spraying box 1 and extends into the inside of the material guiding bin 2. Inside the spraying box 1, a protection structure for positioning and protecting the pipeline is provided;

[0026] The protection structure includes a mounting frame 12. On one side inside the spraying box 1, a mounting frame 12 is provided. Inside the mounting frame 12, a bidirectional lead screw 11 is movably connected. At both ends of the outside of the bidirectional lead screw 11, a group of threaded sleeves 10 are respectively movably connected. Outside the threaded sleeve 10, a connecting plate 22 is fixedly connected. A through groove 9 is opened on one side of the mounting frame 12. The connecting plate 22 penetrates the through groove 9 and is fixedly connected to a support plate 5. One end of the support plate 5 is fixedly connected to a fixing plate 7. One end of the fixing plate 7 is fixedly connected to an arc-shaped plate 6. One end of the arc-shaped plate 6 is fixedly connected to an anti-slip pad 8. One end of the mounting frame 12 is fixedly connected to a servo motor 16;

[0027] The output end of the servo motor 16 penetrates one end of the mounting frame 12 and is fixedly connected to the bidirectional lead screw 11. The connecting plate 22 is slidably connected to the through groove 9;

[0028] The through groove 9 is communicated with the inside of the mounting frame 12. The threaded sleeves 10 at both ends of the outside of the bidirectional lead screw 11 are symmetrically arranged;

[0029] Specifically, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , before spraying, the pipeline is sleeved outside the two support plates 5. Then, the servo motor 16 is started to drive the bidirectional lead screw 11 to rotate. The bidirectional lead screw 11 drives the two connecting plates 22 to move through the threaded sleeves 10 on the outside. The connecting plates 22 drive the two support plates 5 to move towards both ends, and the outside pipeline is supported and positioned through the arc-shaped plate 6. And the anti-slip pad 8 at one end of the arc-shaped plate 6 fits inside the pipeline, which can effectively prevent slipping and improve the stability of the pipeline, realizing convenient positioning of the pipeline to achieve a protection effect.

[0030] Example 2: A connecting disk 14 is fixedly connected to one side of the mounting frame 12. A positioning ring 13 is fixedly connected to one side inside the spraying box 1. A reduction motor 15 is fixedly connected to one side of the spraying box 1;

[0031] The output end of the reduction motor 15 penetrates one side of the spraying box 1 and is fixedly connected to the connecting disk 14. The connecting disk 14 is movably connected to the positioning ring 13;

[0032] The center line of the connecting plate 14 and the center line of the mounting frame 12 are in the same vertical plane, and the center line of the positioning ring 13 and the center line of the connecting plate 14 are in the same horizontal plane;

[0033] Specifically, as Figure 1 , Figure 2 and Figure 3 shown, during spraying, after positioning the pipeline, start the paint pump 3 to introduce the paint into the interior of the material guiding bin 2, and then spray the paint through the spray nozzle 4. At the same time, start the reduction motor 15 to drive the connecting plate 14 to rotate. The connecting plate 14 drives the pipeline on one side through the mounting frame 12 to rotate. While the pipeline is rotating, the spray nozzle 4 can evenly spray the paint on the outside of the pipeline. And the positioning ring 13 inside the spraying box 1 fits on the outside of the connecting plate 14 to support the connecting plate 14 to improve the stability during the rotation of the pipeline, realizing automatic rotation of the pipeline for spraying.

[0034] Embodiment 3: Both ends of the spraying box 1 are fixedly connected with fixing frames 17. One end of the fixing frame 17 is fixedly connected with a fixing cylinder 18. Inside the fixing cylinder 18 is fixedly connected with a dust-proof net 19. One end inside the fixing frame 17 is fixedly connected with a grid plate 20. The other end inside the fixing frame 17 is fixedly connected with a drying fan 21;

[0035] The fixing cylinder 18 communicates with the interior of the fixing frame 17, and the fixing frame 17 communicates with the interior of the spraying box 1;

[0036] Specifically, as Figure 2 shown, after spraying is completed, start the drying fan 21 inside the fixing frame 17. The drying fan 21 can quickly introduce air into the interior of the spraying box 1 through the fixing cylinder 18. While the air inside the spraying box 1 circulates rapidly, it can accelerate the drying speed of the coating on the outside of the pipeline. And the dust-proof net 19 inside the fixing cylinder 18 can effectively prevent dust from entering and polluting the coating, realizing rapid drying of the coating after spraying is completed.

[0037] Working principle: When the utility model is in use, before spraying, the pipeline is sleeved outside the two groups of support plates 5. Then, the servo motor 16 is started to drive the bidirectional lead screw 11 to rotate. The bidirectional lead screw 11 drives the two groups of connecting plates 22 to move through the external thread sleeve 10. The connecting plates 22 drive the two groups of support plates 5 to move towards both ends, and the pipeline outside is supported and positioned by the arc-shaped plates 6. Moreover, the anti-slip pads 8 at one end of the arc-shaped plates 6 are attached to the inside of the pipeline, which can effectively prevent slipping and improve the stability of the pipeline. When spraying, after positioning the pipeline, the paint pump 3 is started to introduce the paint into the material guiding bin 2. Then, the paint is sprayed out through the spraying nozzle 4. At the same time, the reduction motor 15 is started to drive the connecting disc 14 to rotate. The connecting disc 14 drives the pipeline on one side through the mounting frame 12 to rotate. While the pipeline is rotating, the spraying nozzle 4 can evenly spray the paint on the outside of the pipeline. And the positioning ring 13 inside the spraying box 1 is attached to the outside of the connecting disc 14 to support the connecting disc 14 and improve the stability of the pipeline during rotation. After the spraying is completed, the drying fan 21 inside the fixed frame 17 is started. The drying fan 21 can quickly introduce air into the spraying box 1 through the fixed cylinder 18. While the air inside the spraying box 1 circulates quickly, it can accelerate the drying speed of the coating on the outside of the pipeline. And the dust-proof net 19 inside the fixed cylinder 18 can effectively prevent dust from entering and polluting the coating.
