[0045] The right side of the truss 2 is provided with a cleaning mechanism. The cleaning mechanism comprises a shell 42, a dust collection device 43 and a plurality of brush plates 44. The shell 42 is horizontally fixedly installed on the right side of the truss 2 and has a cavity 421 formed in the inside. The brush plates 44 are horizontally and transversely fixedly installed in the shell 42. The dust collection device 43 is fixedly installed on the upper side of the shell 42 and has an input end in communication with the inside of the cavity 421.

[0046] When the device is used to polish the surface of the metal pipe, the effective distance of the conveying mechanism is adjusted according to the pipe specifications. When adjusting, the second telescopic cylinder 21 is started, the second telescopic cylinder 21 is telescoped, the outermost two cross rails 5 are moved, the effective distance between the outermost two cross rails 5 is adjusted, and the distance between the adjacent two cross rails 5 is the same under the cooperation of multiple first springs 20 of the same specification, so that the equal interval distribution is realized.

[0047] When the cross rail 5 moves, the vertical plate 13 is driven to move synchronously by the plug rod 16 and the sleeve 15, so that the third pulley 14 moves and is always aligned with the central axis of the cross rail 5.

[0048] After the distance of the cross rail 5 is adjusted, the distance of multiple groups of driving assemblies in the pushing mechanism is adjusted, the two fourth telescopic cylinders 33 are elongated or shortened, the outermost two sliders 26 are pushed to move, the effective distance between the outermost two sliders 26 is adjusted, the distance between the adjacent two sliders 26 is the same under the cooperation of multiple second springs 32 of the same specification, so that the equal interval distribution is realized, and the bottom end of the friction wheel 28 is opposite to the middle of the two adjacent cross rails 5.

[0049] After adjustment, the device is started, the motor 41 rotates to drive the second cross shaft 38 to rotate, the second cross shaft 38 drives multiple second gears 39 to rotate, the second gears 39 drive corresponding third gears 40 to rotate, the third gears 40 drive the rotating shaft 29 to rotate, the rotating shaft 29 drives the gear ring 30 to rotate through the first gear 31 at the bottom end, the gear ring 30 drives the friction wheel 28 to rotate, and the pipe is pushed.

[0050] The pipe is placed between the two cross rails 5, the bottom edges of the pipe on both sides are in rolling contact with the upper side of the cross rail 5, the third telescopic cylinder 23 is elongated, the hanger 24 is lowered, so that the rotating friction wheel 28 is in contact with the top end of the pipe, and the pipe is pushed. Since the rotating direction of the friction wheel 28 is inclined, when the pipe is pushed, the pipe moves towards the polishing mechanism and rotates by itself.

[0051] When the pipe moves to the bottom side of the abrasive belt 3, the first telescopic cylinder 18 is elongated, the truss 2 is lowered, the bottom surface of the abrasive belt 3 is in contact with the upper side of the metal pipe, and as the truss 2 continuously lowers, the bottom side of the abrasive belt 3 is curved along the outer side of the metal pipe. The multiple third pulleys 14 make the abrasive belt 3 bend to adapt to the arc surface of the upper side of the metal pipe. Since the bottom side of the abrasive belt 3 is curved, the bottom side is tightened, the two second pulleys 11 are pulled to move close to each other, the swing rod 10 is deflected, the torsional spring 12 generates a torque, and the abrasive belt 3 is always in a tension state under the cooperation of the multiple third pulleys 14.

[0052] When the metal pipe passes through the bottom side of the abrasive belt 3, the power device 8 is operated to rotate the abrasive belt 3 through the first pulley 4, the metal pipe is moved and rotated under the pushing of the friction wheel 28, and the rotating direction of the metal pipe is opposite to that of the abrasive belt 3, the outer surface of the metal pipe is rubbed with the abrasive belt 3, so that the rust on the outer layer is polished off, thereby realizing the rust removal effect.

[0053] Under the cooperation of the conveying mechanism and the polishing mechanism, the synchronous polishing operation can be performed on the plurality of metal pipes, and the plurality of metal pipes on the same conveying line can be continuously conveyed under the driving of the pushing mechanism, thereby realizing the batch rust removal and polishing operation, and meeting the batch production schedule requirement of the sunlight room.

[0054] Under the cooperation of the lifting assembly and the adjusting assembly, the plurality of cross rails 5 in the conveying mechanism can be adjusted, so that the effective spacing between the adjacent two cross rails 5 meets different metal pipe specifications, and the stability of conveying is ensured.

[0055] Since different metal pipes need to be applied with different pushing forces, the servo motor 37 is started to drive the first horizontal shaft 36 to rotate, the first horizontal shaft 36 drives the plurality of worm heads 35 to rotate, the worm heads 35 drive the frame body 27 to deflect through the worm gears 34, thereby adjusting the inclination angle of the friction wheel 28, and further changing the vector component force of the pushing, so as to meet the effective pushing of different specifications of pipes, and ensure the high efficiency of polishing.

[0056] During the polishing process, the dust collection device 43 is operated, when the abrasive belt 3 contacted with the rust is rotated to the upper side, the abrasive belt 3 is contacted with the brush plate 44 to generate scraping effect, the rust adhered to the surface of the abrasive belt 3 is cleaned down, and is sucked out by the dust collection device 43, so that the surface of the abrasive belt 3 is cleaned, when the polishing and rust removal is performed again, the adverse effect of the residual rust on the polishing can be avoided, thereby ensuring the polishing and rust removal quality.

[0057] Finally, it should be noted that: the above only describes the preferred embodiments of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
