[0045] Working principle:

[0046] As shown in Figures 1-5:

[0047] By setting up a fixed frame 1, an auxiliary positioning mechanism 2, a fixed upright 3, and an application mechanism 4, when in use, open the control panel 16 and place the pipe on top of the pipe placement guide rail 28. The width of the placement guide rail 28 can be changed to accommodate pipes of different specifications.

[0049] The second positioning bolt 47 positions and installs the application probe 46 and the moving frame 44, facilitating the replacement of application probes 46 with different specifications.

[0050] The first drive motor 34 operates, driving the stirring rod to rotate inside the storage tank 33, and replenishing the required coating liquid into the storage tank 33 through the external pipe 35.

[0051] The second drive motor 5 rotates, driving the reciprocating lead screw 52 to rotate, which in turn moves one side of the sliding block, thereby adjusting the application position of the application mechanism 4.

[0052] The on-site recycling bin 12 is equipped with an air pump that works in conjunction with the on-site recycling pipeline 13. When the air pump inside the on-site recycling bin 12 is running, the corresponding first valve 14 is opened, and the dust particles generated during on-site operations are recycled and processed through the on-site recycling pipeline 13. This not only facilitates manual cleaning later, but also reduces the problem of some residue falling everywhere and causing equipment blockage.

[0053] The control panel 16 is used to control the operation of the first valve 14, the first drive motor 34, the second valve 36, the electric telescopic rod 43, and the second drive motor 5, thereby realizing unified management of the power equipment.

[0054] The positioning base plate 21 has equally spaced threaded holes inside. The first positioning bolt 23 is installed through the threaded holes. The installation positions of the two movable mounting plates 22 are adjusted according to the different pipe specifications placed on the pipe placement guide rail 28 until the pipe can be limited by the two clamps 27. The positioning base plate 21 and movable mounting plates 22 are positioned and installed by the first positioning bolt 23, which improves the stability during the limiting and meets the subsequent coating requirements of pipes of different specifications.

[0055] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way.
