[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] A metal pipe surface spraying device, such as Figure 1-6 As shown, the device includes a main body 1, on which a cover plate 2 is mounted. Air jets 3 and material ejection ports 4 are evenly distributed inside the main body 1, and these ports are arranged in an alternating pattern. Each air jet 3 and material ejection port 4 cooperates with the others.

The jet nozzle 3 and the spray nozzle 4 inside the main body 1 are activated. The spray nozzle 4 sprays the coating material, and the jet nozzle 3 sprays air and forms a spiral airflow inside the main body 1. The airflow flows in along the top opening of the metal pipe and is discharged through the exhaust hole 6. During this period, the airflow drives the coating material to rotate around the metal pipe and evenly cover the surface of the metal pipe, thereby completing the coating of the metal pipe and ensuring that the coating material completely covers the surface of the metal pipe, avoiding waste of the coating material. Furthermore, due to the rapid airflow, the drying speed of the coating material on the surface of the pipe is also accelerated.

[0030] The bracket 7 is connected to several sets of vertically arranged spring coils 8, which mate with the inner wall of the pipe. The spring coils 8 connected to the bracket 7 can better fix the position of the pipe during the spraying process, preventing the pipe from shaking or moving, thereby ensuring the uniformity and accuracy of the spraying.

A spring piece 10 is connected between the two limiting plates 16 and the limiting block 9. When the pipe is inserted into the limiting plate 16 on the limiting block 9, the clamping block 11 fixes the pipe through the spring piece 10, further preventing the pipe from shifting or rotating during spraying. After spraying, the sealing cover 15 is lifted up, and the pipe can be taken out without contacting the outer surface of the pipe, preventing damage to the spraying effect on the surface of the pipe.

The closing cover 15 is provided with a handle 14 connected to the wires 12. Pulling the handle 14 upward will cause the clamping blocks 11 to retract through the wires 12 and engage the clamping of the pipe fitting.

[0033] The handle 13 is installed on the closure cover 15, which provides a convenient holding position for the operator, making it more labor-saving and convenient to install and dismount the closure cover 15.

[0034] The support frame is installed on the bottom surface of the main body 1, which provides a stable support foundation for the entire spraying device, ensuring that the device will not shake or fall during the spraying process, and leaving space at the bottom of the main body 1 for air circulation.

[0035] Working principle: insert the pipe into the limiting plate 16 on the limiting block 9, and fix the pipe by the clamping block 11 through the elastic piece 10, close the closure cover 15 at this time, and then insert the metal pipe into the support 7 on the processing platform 5, during which the spring ring 8 connected to the support 7 can better fix the position of the pipe during the spraying process, preventing the pipe from shaking or moving, then start the device, the air outlet 3 and the material outlet 4 in the main body 1 are started, the material outlet 4 sprays the spraying material, the air outlet 3 sprays air and forms a spiral air flow in the main body 1, the air flow rushes into the exhaust hole 6 through the top opening of the metal pipe, during which the air flow drives the spraying material to rotate around the metal pipe and evenly covers the surface of the metal pipe, thereby completing the spraying of the metal pipe and making the spraying material completely cover the surface of the metal pipe, avoiding waste of the spraying material, and due to the rapid flow of air, the air flow also speeds up the air drying speed of the spraying material on the surface of the pipe, after the spraying is completed, the closure cover 15 on the cover plate 2 is lifted by the handle 13, ensuring that the pipe is taken out without touching the outer surface of the pipe, at this time, the lifting handle 14 is pulled upward, the clamping block 11 is driven to retreat by the silk thread 12, and the clamping of the pipe is contacted.
