Two clamping plates 9 are slidably mounted on the loading plate 4, a sliding frame 7 is slidably mounted on the loading plate 4, two movable blocks 8 are slidably mounted on the sliding frame 7, the two clamping plates 9 are mounted one-to-one with the two movable blocks 8, a transmission groove 13 is provided on the movable block 8, a transmission frame 15 squeezes the transmission groove 13 to make the two movable blocks 8 move away from each other, the two clamping plates 9 clamp the pipe 12, a transmission frame 15 is slidably mounted on the fixed frame 22, when the loading plate 4 approaches the fixed frame 22, the transmission frame 15 squeezes the two clamping plates 9 to move away from each other, an installation groove is provided in the loading plate 4, and the installation groove slides symmetrically Two second racks 33 are installed, and one end of the two second racks 33 is fixedly installed with a movable rod 5, which moves away from the second racks 33 and penetrates the inner wall of the installation groove and is fixedly installed on the transmission chain 2. Two third racks 35 are slidably installed in the installation groove, and the two third racks 35 are located between the two second racks 33. Two second gears 34 are rotatably installed in the installation groove, and the second gears 34 are respectively meshed with the second racks 33 and the third racks 35. The sliding frame 7 is fixedly connected to the third rack 35. A bracket is fixedly installed on the fixed frame 22, and the bracket is respectively fixed on the bracket. A first piston tube 16 and a second piston tube 17 are fixedly installed, a first piston rod is movably inserted into the first piston tube 16, the first piston rod is fixedly connected to the transmission frame 15, a second piston rod is movably inserted into one end of the second piston tube 17, a pressure plate 19 is fixedly installed on the second piston rod, a first connecting tube 18 is connected between the first piston tube 16 and the second piston tube 17, when the loading plate 4 approaches the fixed frame 22, the guide plate 6 squeezes the pressure plate 19, a solenoid valve 21 is provided on the first connecting tube 18, and a pressure switch 20 for controlling the solenoid valve 21 is provided at the end of the second piston tube 17.

[0038] A servo motor for driving the transmission gear 3 to rotate is provided on the lifting frame 1, and the rotation of the servo motor is periodic.

[0039] The servo motor drives the transmission gear 3 to rotate, and the transmission gear 3 drives the transmission chain 2 to rotate, thereby driving the multiple carriers 4 to move. The pipe 12 is placed between the two clamping plates 9. The pipe 12 follows the carrier 4 to be lifted to a high place and completes the flip. During the flipping process, the pipe 12 is turned upside down. When the guide plate 6 on the carrier 4 passes through the fixed frame 22, it is squeezed by the guide rod 24 on the transmission rod 23. The guide plate 6 approaches the fixed frame 22, thereby driving the carrier 4 to approach the fixed frame 22. When the guide plate 6 approaches the fixed frame 22, it squeezes the pressure plate 19, and the pressure plate 19 drives the first A piston rod moves into the first piston tube 16, and the air inside the first piston tube 16 is compressed until the first piston rod squeezes the pressure switch 20, the solenoid valve 21 opens, and the air in the first piston tube 16 enters the second piston tube 17, and the second piston rod extends out of the second piston tube 17. The second piston rod drives the transmission frame 15 to move toward the loading plate, and the transmission frame 15 squeezes the transmission grooves 13 on the two movable blocks 8, so that the two movable blocks 8 move away from each other, thereby making the two clamping plates 9 move away from each other, so that the pipe fitting 12 falls on the fixed frame 22. It is worth noting that a buffer pad is provided on the fixed frame 22.

[0040] It is worth noting that the servo motor rotates intermittently, and each rotation causes the guide rod 24 to move from the symmetry axis of the previous guide plate 6 to the symmetry axis of the next guide plate 6 .

[0041] When the carrier plate 4 moves away from the transmission chain 2, the movable rod 5 does not move, so that the second rack 33 and the second gear 34 move relative to each other, so that the second gear 34 rotates. When the second gear 34 rotates, it drives the third rack 35 to move, thereby driving the sliding frame 7 to move toward the fixed frame 22, so as to increase the feeding distance.

[0042] The detection component includes a first rangefinder 14 fixedly mounted on the carrier plate 4. When the carrier plate 4 approaches the fixed frame 22, the pipe 12 rotates, a friction strip 11 is fixedly mounted on the carrier plate 4, a rotating ring 10 is rotatably mounted on the sliding frame 7, the pipe 12 is fully in contact with the rotating ring 10, the rotating ring 10 is fully in contact with the friction strip 11, a rotating tube 25 is slidably mounted on the carrier plate 4, a cleaning frame 28 and a second rangefinder 32 are provided at the bottom end of the rotating tube 25, a transmission box is fixedly mounted on the side of the carrier plate 4 away from the sliding frame 7, a slider is slidably mounted in the transmission box, a first gear 26 is rotatably mounted on the slider, the rotating tube 25 slides up and down and passes through the center of the first gear 26, and the transmission A first rack 27 matched with the first gear 26 is fixedly installed in the box, a third piston tube 29 is provided on the transmission box, an air intake pipe 30 is movably inserted at the bottom end of the third piston tube 29, the air intake pipe 30 is connected with the rotating tube 25, a blowing pipe connected with the rotating tube 25 is provided on the cleaning frame 28, an extrusion plate 37 is connected between the two third racks 35, an air bag 36 is provided on one side of the extrusion plate 37, a second connecting pipe 31 is connected between the air bag 36 and the third piston tube 29, a screening hole is opened on the fixed frame 22, a flip plate 39 is rotatably installed in the screening hole, a driving motor 38 for driving the flip plate 39 to rotate is provided on the fixed frame 22, and a processor is provided on the fixed frame 22.

[0043] When the sliding frame 7 slides, that is, the sliding frame 7 and the loading plate 4 move relative to each other, the friction strip 11 and the rotating ring 10 generate friction, so that the rotating ring 10 rotates, and the rotating ring 10 drives the pipe 12 to rotate by the friction force (it is worth noting that auxiliary rollers are rotatably installed on the outer wall of the side where the two clamping plates 9 are close to each other, so as to facilitate the rotating ring 10 to drive the pipe 12 to rotate), and the side wall of the pipe 12 is detected by the first rangefinder 14. It is worth noting that the first rangefinder 14 is provided with multiple ones.

[0044] When the sliding frame 7 slides, the rotating tube 25 is driven to move by the slider. During the movement, the first gear 26 and the first rack 27 are transmitted, so that the first gear 26 rotates, thereby driving the rotating tube 25 to rotate. The rotating tube 25 rotates with the cleaning frame 28 and the second rangefinder 32. At the same time, when the third rack 35 moves (the sliding frame 7 moves toward the fixed frame 22), the extrusion plate 37 squeezes the airbag 36, and the air in the airbag 36 enters the third piston tube 29. The third piston tube 29 is provided with a piston disk, and the piston disk is provided with an air intake pipe 30. Under the action of air pressure, the piston disk moves downward, and the air intake pipe 30 moves the rotating tube 25 downward. During the downward movement, the air in the third piston tube 29 enters the rotating tube 25 through the air intake pipe 30, and is then blown out by the air blowing pipe. The inner wall of the pipe 12 is first cleaned, and then the second rangefinder 32 is used for distance measurement.

[0045] The processor collects the measurement results of the first rangefinder 14 and the second rangefinder 32. For the first rangefinder 14, the results of each first rangefinder 14 are compared, and then the measurement results of different first rangefinders 14 are compared. If the difference between the measurement results is small (a threshold value of the difference can be set), it is qualified. On the contrary, if the difference between one of the comparison results is large, it is unqualified.

[0046] The second distance meter 32 measures the inner side of the pipe 12 from top to bottom, and also compares the results. If the difference between the measurement results is small (a threshold value of the difference can be set), it is qualified. On the contrary, if the difference between one of the comparison results is large, it is unqualified.

[0047] A controller is also provided, and when the measurement is qualified, the drive motor 38 will not be started, and the pipe 12 can fall on the fixed frame 22, and a slope can be provided on the fixed frame 22, and the slope is connected to a conveyor belt. When the measurement is unqualified, the drive motor 38 is started, the flip plate 39 rotates, and the pipe 12 falls from the screening hole, and another conveyor belt can be provided below the screening hole.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
