Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] During specific implementation: As Figures 1-5 shown, an automatic spraying machine for pipe surface treatment includes a spraying base 1 and a clamping base 2: The spraying base 1 is a spraying area, and the clamping base 2 is a pipe angle adjustment area. The spraying base 1 and the clamping base 2 are connected;

[0025] The spraying area is respectively provided with a movable fixing plate 19 and a liquid storage tank 16. The fixing plate 19 is located on the side of the liquid storage tank 16, and the distance between the fixing plate 19 and the angle adjustment area is less than the distance between the liquid storage tank 16 and the angle adjustment area. A spraying structure 22 is provided on one side of the liquid storage tank 16 close to the fixing plate 19;

[0026] The bottom of the angle adjustment area is provided with a support structure for lifting the pipe, and limit mechanisms for adjusting the pipe angle are provided on both sides of the support structure;

[0027] The spraying structure 22 includes a water pump 21 and a spraying machine body 20. The water pump 21 is arranged on the side of the liquid storage tank 16. The water pump 21 is connected to the spraying machine body 20 through a pipeline. The spraying machine body 20 is arranged at the upper end of the fixing plate 19.

[0028] When the device is in use, after the pipeline is fixed and spraying is required, first inject anticorrosive paint into the liquid storage tank 16, and then turn on the water pump 21 to pump the paint inside the liquid storage tank 16 into the spraying machine body 20 by the water pump 21. Then, the spraying machine body 20 sprays the paint onto the surface of the pipeline to spray the surface of the pipeline.

[0029] A threaded rod 18 is rotatably arranged inside the spraying area. The threaded rod 18 is connected to the output end of the third motor 17. The third motor 17 is arranged on the side of the spraying base 1. A fixing plate 19 is threadedly connected to the outside of the threaded rod 18. The fixing plate 19 is in contact with the spraying base 1.

[0030] The limiting mechanism includes a telescopic block 4, a support plate 5, a first motor 7 and a clamping disc 8. Telescopic blocks 4 are slidably arranged inside both sides of the clamping base 2. A support plate 5 is arranged above the end of the telescopic block 4 far from the clamping base 2. Clamping discs 8 are rotatably arranged on the side of the two support plates 5 facing each other. A first motor 7 is arranged on the other side of the support plate 5, and the output end of the first motor 7 is connected to the support plate 5. A friction pad 9 is arranged on the side of the clamping disc 8.

[0031] When the device is in use, first place the pipeline body 6 on the surface of the placement plate 15, and then turn on the second motor 10 to drive the lead screw 11 to rotate. Since the threads on both sides of the lead screw 11 are opposite, the two movable blocks 12 move inward on the surface of the lead screw 11 at the same time, so that the movable blocks 12 drive the telescopic blocks 4 to move inward at the same time, thereby driving the support plate 5 to move by the telescopic blocks 4.

[0032] The support structure includes an electric push rod 13, a sliding block 14 and a placement plate 15. The electric push rod 13 is arranged on the side of the baffle 3 far from the spraying base 1. The lower end of the electric push rod 13 is provided with a sliding block 14. The sliding block 14 penetrates through the baffle 3, and a chute for the sliding block 14 to move up and down is opened inside the baffle 3. A placement plate 15 is arranged on the side of the sliding block 14. The placement plate 15 is located on the other side of the baffle 3. The pipeline body 6 is arranged at the upper end of the placement plate 15.

[0033] When the device is in use, first place the pipeline body 6 on the surface of the placement plate 15. At this time, turn on the electric push rod 13 to expand and contract, so that the electric push rod 13 drives the sliding block 14 to move, so that the sliding block 14 drives the placement plate 15 to move, so that the placement plate 15 lifts the pipeline body 6, so that the position of the pipeline body 6 can be located at the center of the clamping disc 8, so as to facilitate the clamping disc 8 to clamp and fix the pipeline body 6.

[0034] A second motor 10 is arranged on the side of the clamping base 2. The output end of the second motor 10 is provided with a double-threaded lead screw 11. Two movable blocks 12 are arranged at intervals on the surface of the lead screw 11. The two movable blocks 12 are slidably connected to the clamping base 2, and the two movable blocks 12 are respectively connected to the corresponding telescopic blocks 4.

[0035] When the device is in use, it is necessary to translate the spraying machine body 20. At this time, turn on the third motor 17, so that the third motor 17 drives the threaded rod 18 to rotate, so that the fixing plate 19 moves on the surface of the threaded rod 18, so that the fixing plate 19 drives the spraying machine body 20 to translate, so that the spraying machine body 20 can fully spray the surface of the pipeline.

[0036] When the device is in use, the two side support plates 5 are driven by the telescopic blocks 4 to move inward at the same time. At this time, the support plates 5 drive the clamping discs 8 to move, so that the clamping discs 8 drive the friction pads 9 to fit with the pipeline body 6, so as to clamp and fix the pipeline body 6. And because the two clamping discs 8 move at the same time, the pipeline body 6 can be kept in the middle position. The friction pads 9 can increase the friction force between the pipeline body 6 and the clamping discs 8, so as to prevent the pipeline body 6 from falling off, and enable the device to adapt to pipeline bodies 6 of different lengths, improving the practicability of the device.

[0037] When the utility model is in use, first place the pipeline body 6 to be sprayed on the surface of the placement plate 15. Then, turn on the second motor 10 to drive the lead screw 11 to rotate, so that the movable block 12 moves on the surface of the lead screw 11, driving the support plate 5 to move, pushing the clamping disc 8 to move, making the friction pad 9 fit with the pipeline body 6 to clamp and fix the pipeline body 6. Then, the electric push rod 13 extends to push the placement plate 15 to move downward and separate from the pipeline body 6. When the pipeline body 6 needs to be sprayed, turn on the water pump 21 at this time to pump the paint into the interior of the spraying machine body 20 by the water pump 21. Then, the spraying machine body 20 sprays the paint onto the surface of the pipeline body 6. At this time, turn on the third motor 17 to drive the threaded rod 18 to rotate, so that the fixing plate 19 moves on the surface of the threaded rod 18, and the fixing plate 19 drives the spraying machine body 20 to translate to fully spray one side of the pipeline body 6. Then, turn on the first motor 7 to drive the clamping disc 8 to rotate, so that the pipeline body 6 rotates, enabling the spraying machine body 20 to spray different positions of the pipeline body 6. There is no need to manually rotate the pipeline body 6, improving the spraying efficiency, and the motors of this device all have a self-locking function.

[0038] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
