[0025] Specifically, on the top surfaces on both sides of the device rack 1, there are symmetrically installed contact racks 11 that act on the limit of the top cover 5, which can avoid interference during feeding and discharging. On one side of each contact rack 11, there is fixedly installed an electromagnetic sheet 13 that acts on the positioning of the top cover 5 to prevent random sliding. On the arc surfaces on both sides of the top cover 5, there are embedded two arc-shaped magnetic sheets, and there is an electromagnetic connection between the arc-shaped magnetic sheets and the electromagnetic sheets 13. The top cover 5 is limited between the two contact racks 11.

[0026] Furthermore, on the top surface of the device rack 1, there is a sliding groove opened to facilitate the horizontal sliding of the top cover 5. The sliding groove is located between the two contact racks 11. On the top cover 5, there are also symmetrically installed two sliding pieces 7. On the bottom surface of the sliding piece 7, there is a connecting ball, and the connecting ball is movably connected in the sliding groove to make the top cover 5 more stable during movement.

[0027] In this embodiment, on the top end of the inner adjusting rack 16, there is installed a limit disk. On the outer side of the limit disk, there are fixed multiple limit claws. In the placing disk 4, there is a placing groove opened, and the limit disk is connected in the placing groove. The fin body 2 is placed in the limit disk. The bottom end of the inner adjusting rack 16 penetrates to the bottom side of the placing disk 4. On the bottom end of the inner adjusting rack 16, there is a rotatably connected chassis 10 to prevent the chassis 10 from rotating when the inner adjusting rack 16 rotates, and to avoid rotational wear on the raised strip 15 over a long time. On the bottom surface of the chassis 10, there is fixedly installed a contact block 14. In the device rack 1, there is installed a raised strip 15, and both ends of the raised strip 15 are in a downhill shape. On the bottom end of the contact block 14, there is installed a rolling ball, and the rolling ball is movably connected on the raised strip 15 to reduce the friction during movement. Between the bottom surface of the placing disk 4 and the bottom end of the inner adjusting rack 16, there is a spring connection to achieve the rapid reset of the inner adjusting rack 16 and avoid collision. The inner circular plate 61 is arranged inside the top cover 5, and the gear plate 6 is installed on the top surface of the top cover 5. Between the inner circular plate 61 and the gear plate 6, there is fixedly installed a positioning shaft, and the positioning shaft is rotatably connected inside the top cover 5. On the bottom surface of the inner circular plate 61, there are fixedly installed multiple connecting insertion rods 62, and the bottom ends of the connecting insertion rods 62 are inserted on the top surfaces of the limit claws. On the top surface of the placing disk 4 and the bottom surface of the top cover 5, there are symmetrically installed two groups of magnetic blocks 17, and the two groups of magnetic blocks 17 are installed with opposite polar directions to avoid front-back adsorption. The device rack 1 is also installed with a support frame 12, and both sides of the support frame 12 are fixed on the outer surface of the device rack 1 to avoid collision with the sliding pieces 7. On the top surface of the support frame 12, there is installed a second motor 9, and the toothless piece 8 is connected to the output end of the second motor 9.

[0028] Working principle: When the equipment is working, the fin body 2 is placed in the position corresponding to the placement disk 4, and then the first motor 3 is controlled to rotate, the placement disk 4 will move forward, and when it moves to the bottom side of the top cover 5, under the magnetic connection of the two sets of magnetic blocks 17, the top cover 5 will be covered on the placement disk 4, and the two will move synchronously. When moving to the raised strip 15, the contact block 14 will push the inner adjustment frame 16 upward, the spring will be squeezed, and the limit disk will lift the fin body 2 upward. When it is lifted to a certain height, the connecting rod 62 in the top cover 5 will be inserted into the limit claw. When it moves to the bottom side of the support frame 12, the first motor 3 will Stop, then the second motor 9 will rotate ninety degrees. If there are no teeth in the corresponding area, the gear plate 6 does not rotate, and the first motor 3 works again to continue to transport the placement plate 4 forward. However, when it is transported to the abutment frame 11, the electromagnetic plate 13 will be energized to adsorb the top cover 5, and the placement plate 4 on the bottom side will continue to move to the material picking end. After picking up the material, the first motor 3 is controlled to reverse, and the above operation is reversed to return to the initial position, and then the second transportation is carried out. During the second transportation process, the tooth-missing piece 8 will rotate for the third time. At this time, the tooth-missing piece 8 will engage with the gear plate 6, and the rotation of the gear plate 6 drives the inner adjustment frame 16 to rotate, and the fin body 2 completes a ninety-degree rotation.
