The half-tooth on the connecting plate first meshes with a first gear to control the rotation shaft to rotate. The rotation shaft drives the turntable below to rotate. The turntable drives the corresponding water spray rack to move through two adjusting rods and moving rods.

The two moving blocks drive the connecting block to move through the telescopic rods below. The connecting block drives the two limiting rods to rotate together. The two limiting rods drive the two clamping blocks to limit the two side walls of the flat aluminum tubes. At this time, the first hydraulic cylinder in the cleaning chamber controls the movement of the first connecting plate. The first connecting plate drives the flat aluminum tubes to continue to move, so that the flat aluminum tubes pass through the opening on the partition plate and pass through the second opening on the first connecting plate in the drying chamber;

[0019] S4: When the flat aluminum tubes pass through the opening on the second connecting plate, according to the width of the flat aluminum tubes, the second hydraulic cylinder controls the movement of the rack. When the rack moves, it will control the rotation of the second gear. The second gear controls the movement of another rack. The two racks control the movement of the two connecting frames together. The second nozzles on the two connecting frames spray hot steam to dry the flat aluminum tubes. And one water spray rack is connected to the second connecting plate through the second connecting rod, so that the second connecting plate performs reciprocating motion, and a position can be cleaned quickly and multiple times;

[0020] S5: Then, the clamping assembly in the drying chamber controls the flat aluminum tubes to continue to move, so that the flat aluminum tubes move onto the conveyor belt below. The conveyor belt controls the flat aluminum tubes to move out of the cleaning tank for the next operation.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: By using an integrated clamping device, cleaning system and drying system, the synchronous cleaning and immediate drying of the four sides of the flat aluminum tubes can be efficiently achieved. This process not only ensures the thorough cleaning of the surface of the flat aluminum tubes, but also can quickly evaporate the residual moisture, effectively preventing the secondary deposition of dust on the surface of the flat aluminum tubes, thereby maintaining its cleanliness and smoothness.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] In order to make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments of the present invention. Obviously, the embodiments described below are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this patent.

[0031] Refer to Figure 1 - Figure 6 , a flat aluminum tube feeding mechanism, including a cleaning box 1. First openings 6 are provided on both side walls of the cleaning box 1. Conveyor belts 4 are provided on both sides of the cleaning box 1. One conveyor belt 4 conveys the flat aluminum tubes into the cleaning box 1, and the other conveys the cleaned flat aluminum tubes to the next step. The two conveyor belts 4 respectively pass through the two first openings 6 and extend into the cleaning box 1. The conveyor belt 4 can transport the flat aluminum tubes. A partition 10 is provided in the cleaning box 1. The partition 10 divides the cleaning box 1 into a cleaning chamber and a drying chamber. Clamping components are provided in both the cleaning chamber and the drying chamber. The clamping components can move to clamp and move the materials conveyed by the flat aluminum tubes. A cleaning component is provided in the cleaning chamber, and a drying component is provided in the drying chamber. The cleaning component includes a moving frame 8. Two water spraying frames 34 and a second cleaning frame 41 are slidably connected to the moving frame 8. The cleaning frame 41 is located between the two water spraying frames 34. One water spraying frame 34 first rinses the surface of the flat aluminum tube, and then the cleaning frame 41 cleans. After the cleaning is completed, the other water spraying frame 34 rinses again to clean the impurities on the surface of the flat aluminum tube; The drying component includes two connecting frames 33. First nozzles 31 are provided on the opposite sides of the two connecting frames 33. The first nozzles are used to spray hot steam. The drying component quickly evaporates the moisture on the surface of the flat aluminum tube, preventing dust from adhering to the surface of the flat aluminum tube and ensuring the subsequent operations of the flat aluminum tube.

[0032] Refer to Figures 2 - 5 , a placing plate 5 is provided on the upper surface of the moving frame 8. A placing rack 20 is provided on the placing plate 5. A first motor 19 is connected to the placing rack 20. A connecting disk 18 is connected to the output shaft of the first motor 19. A plurality of half teeth 17 are connected to one side surface of the connecting disk 18. A rotating shaft 15 is rotatably connected to the placing plate 5. Two first gears 16 are connected to the upper end of the rotating shaft 15. One of the first gears 16 meshes with the half teeth 17 on the connecting disk 18. The lower end of the rotating shaft 15 passes through the placing plate 5 and extends below the placing plate 5. The two first gears 16 control the rotating shaft 15 to rotate forward and backward, thereby driving the lower turntable 40 to rotate forward and backward;

[0033] The lower end of the rotating shaft 15 is connected to a turntable 40. Two adjusting rods 38 are connected to the surface of the turntable 40. A moving rod 37 is rotatably connected to the adjusting rod 38. One end of the moving rod 37 away from the adjusting rod 38 is rotatably connected to the water spraying frame 34. The moving rod 37 controls the water spraying frame 34 to slide left and right along the length direction of the placing plate 5. The water spraying frame 34 is connected to the moving frame 38 through a first slider 35. The first slider 35 facilitates the sliding of the water spraying frame 34 on the moving frame 38. The cleaning frame 41 is located below the turntable 40. A second connecting rod 39 is connected between one of the water spraying frames 34 and the cleaning frame 41. When the turntable 40 rotates, it drives the two water spraying frames 34 to reciprocate through the two moving rods 37, so that the water spraying frame 34 and the cleaning frame 41 perform multiple water sprayings and cleanings, cleaning a position of the flat aluminum tube multiple times and cleaning the pipeline clean. The two water spraying frames 34 and the cleaning frame 41 are both arranged in a loop shape. A plurality of second nozzles 36 are arranged on the two water spraying frames 34. The loop shape can clean the four sides of the flat aluminum tube simultaneously, improving the cleaning efficiency.

[0034] Refer to Figure 1 and Figure 3 , the clamping assembly includes a first connecting plate 12. Two moving blocks 3 are slidably connected to the first connecting plate 12. The two moving blocks 3 are connected by a positive and negative thread screw rod 22. A fixing plate 21 is arranged on one side of the first connecting plate 12. A second motor is connected to the fixing plate 21. The output shaft of the second motor is connected to the positive and negative thread screw rod 22. The lower ends of the two moving blocks 3 are connected to telescopic rods 24. The lower ends of the telescopic rods 24 are connected to connecting blocks 23. The lower ends of the two connecting blocks 23 are respectively hinged with limiting rods 25. One end of the limiting rod 25 away from the connecting block 23 is hinged on the first connecting plate 12. Clamping blocks 26 are connected to the opposite sides of the two limiting rods 25. A second opening 27 is arranged on the first connecting plate 12. The second opening 27 is located between the two clamping blocks 26. The side walls of the cleaning chamber and the drying chamber are both connected with a first hydraulic cylinder 2. The piston rod of the first hydraulic cylinder 2 is connected to the first connecting plate 12. When the positive and negative thread screw rod 22 rotates, it drives the two moving blocks 3 to move towards each other, and then makes the limiting rod 25 rotate through the connecting block 23, so that the two clamping blocks 26 limit the two sides of the flat aluminum tube. The shape of the clamping block 26 can be adjusted according to the shape of the flat aluminum tube. Then the first hydraulic cylinder 2 controls the movement of the first connecting plate 12, so that the end of the first connecting plate 12 passes through the partition plate 10 and is conveyed to the clamping assembly in the drying chamber. When the clamping assembly clamps, the front part of the flat aluminum tube first passes through the second opening 27. When the middle part is near the second opening 27, the clamping block 26 clamps again, facilitating the conveying of the flat aluminum tube.

[0035] Refer to Figure 6, a second connecting plate 13 is slidably connected to the side wall of the drying chamber. A second gear 28 is connected to the second connecting plate 13. Two racks 29 are slidably connected to the second connecting plate 13. The two racks 29 are located on both sides of the second gear 28. Vertical rods 30 are connected to both racks 29. The lower ends of the two vertical rods 30 are respectively connected to two connecting frames 33. A second hydraulic cylinder 32 is connected to the second connecting plate 13. One end of the second hydraulic cylinder 32 is connected to one of the racks 29. The water spraying frame 34 is connected to the second connecting plate 13 through a first connecting rod 14. First, the water spraying frame 34 and the second connecting plate 13 are connected. When the water spraying frame 34 reciprocates, it will drive the second connecting plate 13 to reciprocate together, so that the flat aluminum tube can also be quickly dried. Moreover, the setting of the two racks 29 and the second gear 28 can be adjusted according to the width of the flat aluminum tube.

[0036] Refer to Figure 1 , a placement box 9 is arranged at the bottom of the cleaning chamber. Baffles 7 are connected to both sides of the placement box 9. The two baffles 7 are respectively connected to the two side walls of the cleaning chamber. The placement box 9 is located below the moving frame 8. The setting of the baffles 7 and the placement box 9 can receive waste water and transport it through a pipeline to avoid the accumulation of waste water at the lower part of the cleaning box 1.

[0037] A usage method of a flat aluminum tube feeding mechanism, using the flat aluminum tube feeding mechanism as described above, includes the following usage steps:

[0038] S1: The conveyor belt 4 in front of the cleaning box 1 transports the flat aluminum tube into the cleaning box 1;

[0039] S2: The conveyor belt 4 continues to control the flat aluminum tube to be below the moving frame 8. At this time, the first motor 19 drives the connecting disk 18 to rotate. The half teeth 17 on the connecting disk 18 first mesh with one of the first gears 16 to control the rotation of the rotating shaft 15. The rotating shaft 15 drives the lower turntable 40 to rotate. The turntable 40 drives the corresponding water spraying frame 34 to move through two adjusting rods 38 and a moving rod 37. As the connecting disk 18 rotates, the half teeth 17 on the connecting disk 18 will mesh with the other first gear 16, thereby controlling the reverse rotation of the rotating shaft 15, causing the turntable 40 to reset, and thus causing the water spraying frame 34 to reset again, so that the water spraying frame 34 and the adjusting rod 38 perform reciprocating motion. One water spraying frame 34 first cleans the flat aluminum tube, and at the same time, the second connecting rod 39 in the middle position drives the cleaning frame 41 to clean the side wall of the flat aluminum tube. The other water spraying frame 34 sprays water on the surface of the flat aluminum tube after cleaning again to clean the surface of the flat aluminum tube;

[0040] S3: The flat aluminum tube passes through the second opening 27 on the first connecting plate 12. At this time, the second motor controls the rotation of the left - right threaded lead screw 22, thereby controlling the two moving blocks 3 to move towards each other. The two moving blocks 3 drive the connecting block 23 to move through the telescopic rod 24 below. The connecting block 23 drives the two limiting rods 25 to rotate together. The two limiting rods 25 drive the two clamping blocks 26 to limit the two side walls of the flat aluminum tube. At this time, the first hydraulic cylinder 2 in the cleaning chamber controls the movement of the first connecting plate 12. The first connecting plate 12 drives the flat aluminum tube to continue moving, so that the flat aluminum tube passes through the opening on the partition plate 10 and passes through the second opening 27 on the first connecting plate 12 in the drying chamber;

[0041] S4: When the flat aluminum tube passes through the opening on the second connecting plate 13, according to the width of the flat aluminum tube, the second hydraulic cylinder 32 controls the movement of the rack 29. When the rack 29 moves, it controls the rotation of the second gear 28. The second gear 28 controls the movement of the other rack 29. The two racks 29 control the two connecting frames 33 to move together. The second nozzles 31 on the two connecting frames 33 spray hot steam to dry the flat aluminum tube. And a water - spraying frame 34 is connected to the second connecting plate 13 through the second connecting rod 39, so that the second connecting plate 13 makes a reciprocating motion, and can quickly clean a position multiple times;

[0042] S5: Then, the clamping assembly in the drying chamber controls the flat aluminum tube to continue moving, so that the flat aluminum tube moves onto the conveyor belt 4 below. The conveyor belt controls the flat aluminum tube to move out of the cleaning box 1 for the next operation.

[0043] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.

At this time, the first hydraulic cylinder (2) in the cleaning chamber controls the first connecting plate (12) to move, and the first connecting plate (12) drives the flat aluminum tube to continue to move, so that the flat aluminum tube passes through the opening on the partition (10), and the flat aluminum tube passes through the second opening (27) on the first connecting plate (12) in the drying chamber; S4: When the flat aluminum tube passes through the opening on the second connecting plate (13), the two connecting frames (33) are moved according to the width of the flat aluminum tube, and the second hydraulic cylinder (32) controls the rack (29) to move. When the rack (29) moves, it controls the second gear (28) to rotate. The second gear (28) controls the movement of another rack (29). The two racks (29) control the two connecting frames (33) to move together. The second nozzles (31) on the two connecting frames (33) spray hot steam to dry the flat aluminum tube, and a water spray frame (34) is connected to the second connecting plate (13) through a second connecting rod (39), so that the second connecting plate (13) reciprocates, and a position can be cleaned quickly and multiple times; S5: Then, the clamping assembly in the drying chamber controls the flat aluminum tube to continue to move, so that the flat aluminum tube moves to the conveyor belt (4) below. The conveyor belt controls the flat aluminum tube to move out of the cleaning box (1) to perform the next operation.
