The output shaft of the servo motor 212 is fixedly connected to one end of the worm 211 via a coupling. The servo motor 212 is electrically connected to the controller 213 via wires.

[0027] There are four receiving slots 23 arranged in a circular array along the circumference of the turntable 22. The included angle between adjacent receiving slots 23 is 90 degrees. The number of electric push rods 24 and push plates 25 are the same as the number of receiving slots 23, and they are set one-to-one.

[0028] The conveying assembly 3 includes a first conveyor 31 and a second conveyor 32, both of which are belt conveyors, and their conveying speed can be adjusted by a controller 213. The first conveyor 31 is located on one side of the turntable 22, and its conveying direction is towards the turntable 22. The conveying assembly 3 also includes a first support rod 33, which is fixed to the ground by bolts. A first docking slide plate 34 is welded and fixed to its top. The first docking slide plate 34 is made of stainless steel and has a smooth surface. It is located between the turntable 22 and the first conveyor 31. The second conveyor 32 is located on the other side of the turntable 22, and its conveying direction is away from the turntable 22. The conveying assembly 3 also includes a second support rod 36, which is fixed to the ground by bolts. A second docking slide plate 37 is welded and fixed to its top. The second docking slide plate 37 is also made of stainless steel and is located between the turntable 22 and the second conveyor 32.

[0029] The top of the first docking slide plate 34 is flush with the top of the first conveyor 31, with a height difference of no more than 2mm; the edge of the top of the first docking slide plate 34 facing the first conveyor 31 is rounded with a radius of 5mm-10mm; the top of the first docking slide plate 34 is fixedly connected to the first sliding block 35 by screws. The first sliding block 35 is made of rubber and protrudes 3mm-5mm above the surface of the slide plate, with the protruding side facing the turntable 22.

[0030] The top of the second docking slide plate 37 is flush with the top of the second conveyor 32, with a height difference of no more than 2mm; the edge of the top of the second docking slide plate 37 facing the turntable 22 is rounded with a radius of 5mm-10mm; the top of the second docking slide plate 37 is fixedly connected to the second sliding block 38 by screws. The second sliding block 38 is made of rubber and protrudes 3mm-5mm above the surface of the slide plate, with the protruding side facing the second conveyor 32.

[0031] Working principle: When the carton flipping feeding device is working, the controller 213 first presets the flipping angle of the turntable 22, which is usually 90 degrees or 180 degrees, the speed of the servo motor 212, and the extension and retraction stroke of the electric push rod 24. The cardboard box to be flipped is conveyed by the first conveyor 31 to the first docking slide plate 34. Under the thrust of the first conveyor 31 and the guiding action of the first sliding block 35, the cardboard box slides into the receiving slot 23 on the turntable 22 in the receiving position via the first docking slide plate 34. The rounded corner treatment of the first docking slide plate 34 avoids the edge of the cardboard box from getting stuck. When the carton enters the receiving slot 23, the photoelectric sensor on one side of the inner wall of the receiving slot 23 detects the carton and transmits the signal to the controller 213. After receiving the signal, the controller 213 controls the servo motor 212 to start. The output shaft of the servo motor 212 drives the worm gear 211 to rotate. The worm gear 211 meshes with the worm wheel 29, thereby driving the active synchronous pulley 28 to rotate. The active synchronous pulley 28 drives the driven synchronous pulley 26 to rotate through the synchronous toothed belt 27, thereby driving the turntable 22 to rotate around the bracket 21 to the preset flip angle. At this time, the receiving slot 23 containing the carton is aligned with the second docking slide plate 37. Subsequently, the controller 213 controls the electric push rod 24 corresponding to the receiving slot 23 to extend. The electric push rod 24 pushes the push plate 25 to slide in the receiving slot 23, pushing the carton out of the receiving slot 23. Under the pushing force of the push plate 25, the carton slides into the second conveyor 32 through the second docking slide plate 37. The rounded corner treatment of the second docking slide plate 37 and the guiding effect of the second sliding block 38 ensure the smooth transfer of the carton. The second conveyor 32 transports the flipped carton to the next process. As the turntable 22 rotates, the next receiving slot 23 rotates synchronously to align with the first docking slide 34, receiving new cartons from the first conveyor 31. This cycle repeats, achieving continuous carton flipping and feeding operations.
