In order to realize the stable clamping of the air pipe 170, the lower roller 111 is designed as a double-row structure, one row is the driving roller 111a, which is driven by the first motor 114 through the shaft 112 and the coupling 113, and can rotate under the driving of the first motor 114, thereby driving the air pipe 170 to rotate, the other row is the driven roller 111b, which is used for auxiliary positioning of the air pipe 170. The air pipe 170 is arranged above the middle of the driving roller 111a and the driven roller 111b, and can rotate around the axis under the friction force of the driving roller 111a. The upper pressure roller 115 is arranged above the middle of the two rows of lower rollers 111, and the stable clamping of the air pipe 170 is realized by the two rows of lower rollers 111 and the upper pressure roller 115. The upper pressure roller 115 is installed on the rack 160 through the mounting bracket 116, and the lower roller 111 and the upper pressure roller 115 are arranged in multiple along the length direction of the air pipe 170 to realize stable clamping. The multiple upper pressure rollers 115 are installed on the mounting bracket 116 through the roller rod 117, and the upper pressure roller 115 and the driven roller 111b are both rotatably installed to reduce the rotation resistance of the air pipe 170.

[0031] Working principle: the driving roller 111b is driven to rotate by the first motor 114, and the air pipe 170 above it is driven to rotate by friction; the upper pressure roller 115 is driven to lift by the air cylinder 118, realizing the fixation of the air pipe 170 in the axial direction, and the height can also be adjusted according to the diameter size of the air pipe 170 to adapt to the installation requirements of air pipes 170 with different outer diameters.

[0032] 2. Polishing device 120:

[0033] Structural composition: including the feeding rod 121, the polishing head 122 and the second motor 123. One end of the feeding rod 121 is connected with the polishing head 122, and the other end can be drivingly connected with the second motor 123 through the belt transmission mechanism 124. The second motor 123 drives the feeding rod 121 and the polishing head 122 to rotate, realizing the polishing of the inner wall of the air pipe 170. The polishing head 122 can be made of wear-resistant material for directly contacting and polishing the inner wall of the air pipe 170.

By limiting the feeding stroke of the feeding device 130, the polishing requirements of pipe fittings with different lengths can be realized.

[0037] Working principle: the third motor 131 converts the rotary motion into linear motion through the screw drive mechanism 132, and drives the feed rod 121 to move along the axial direction of the air pipe 170.

In order to further improve the polishing efficiency, the rotating direction of the polishing head 122 is opposite to the rotating direction of the air duct 170.

[0048] 4. If deep cleaning is required during the polishing process, the cleaning agent delivery pump 142 can be turned on to deliver the cleaning agent through the inner tube 121b to the nozzle for spraying.
