Technical Field
[0001] This utility model relates to the field of cardboard box production, specifically to an anti-tipping limiting structure for automatic tilting of corrugated cardboard boxes. Background Technology
[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to create corrugated boxes. Corrugated boxes are one of the most widely used packaging products, consistently ranking first in usage among all packaging materials. This includes calcium-plastic corrugated boxes. For over half a century, corrugated boxes have gradually replaced wooden crates and other transport packaging containers due to their superior performance and easy processing, becoming the mainstay of transport packaging. Besides protecting goods and facilitating warehousing and transportation, they also beautify and promote products. Corrugated boxes are environmentally friendly products, benefiting both environmental protection and ease of loading and unloading.
[0003] Chinese patent discloses an automatic box-flipping structure for a carton-stapler used in corrugated cardboard box production (authorization announcement number CN216373531 U). This patented technology uses two sets of sliding grooves and two sets of limiting strips between the rotating drum and the rotating rod to allow the rotating rod to rotate while moving horizontally, thus achieving automatic box flipping. However, since the rotating rod and support frame drive the box flipping, the lack of a limiting structure on the rotating rod makes it easy for the box to overturn, preventing it from facing upwards and affecting subsequent assembly. Therefore, those skilled in the art have provided an anti-tipping limiting structure for automatic corrugated cardboard box flipping to solve the problems mentioned in the background art.

A motor is installed at the left end of the threaded rod, and a threaded sleeve is fitted on the outer surface of the threaded rod. The upper end of the threaded sleeve is fixedly connected to a transverse plate.
[0009] Preferably, the outer surface of the rotating rod is rotatably connected to a support block, and the support block is fixed to the upper end of the transverse plate.
[0010] Preferably, the positioning mechanism includes a movable plate and a positioning block. The movable plate has a mating hole inside and is sleeved on the outer surface of the positioning rod through the mating hole. A groove is opened at the left end of the movable plate, and a buckle block is slidably connected inside the groove.

[0015] The technical effects and advantages of this utility model are as follows:
[0016] This invention selects the protruding right-angle blocks according to the side of the carton that needs to be attached. Pushing the moving plate moves the square blocks and right-angle blocks, so that the right-angle blocks pass through the square holes and are placed at the right end of the circular plate. When the circular plate rotates and flips the carton through the rotating rod and support frame, the circular plate drives several right-angle blocks to rotate. By pressing the trigger block through the limiting block, the sliding plate presses the trigger switch, and the rotating rod stops rotating. At the same time, the limiting block blocks the right-angle blocks, giving the right-angle blocks a limiting force, so that the carton can be stably facing upwards, preventing the carton from turning over and ensuring the carton attachment effect. At the same time, it also ensures that the return pusher can push the carton to fall stably onto the conveyor belt for transmission, and the carton will not tip over. Attached Figure Description

The moving plate 20 is on the left end of the positioning rod 15. A groove 22 is provided at one end, and a latching block 23 is slidably connected inside the groove 22. Guide protrusions 24 are symmetrically installed on the inner wall of the groove 22, and the guide protrusions 24 pass through the latching block 23. A spring 25 is symmetrically installed on one end of the latching block 23, and a positioning block 26 is installed on the other end of the latching block 23, and the positioning block 26 passes through the side of the mating hole 21. A right-angle block 27 is installed on the right end of the square block 18, and a trigger mechanism 28 is installed inside the right-angle block 27.

Motor 6, motor 40, electric telescopic rod 2, electric telescopic rod 37 and electric telescopic rod 41 are all connected to external controllers.
[0030] The working principle of this utility model is as follows: the carton is placed outside the support frame 11, and the fixed plate 3 and the transverse plate 8 are raised and lowered by the electric telescopic rod 2, thereby adjusting the height of the carton. The threaded rod 5 is rotated by the motor 6, and the threaded rod 5 moves the transverse plate 8 through the threaded sleeve 7, thereby adjusting the lateral position of the carton.
[0031] The right-angle block 27 is selected according to the side of the carton that needs to be attached. One right-angle block 27 corresponds to one side of the carton. The positioning block 26 is moved away from a positioning hole 17 by the latching block 23. At the same time, the latching block 23 compresses the spring 25. Then, the moving plate 20 is pushed to move outside the positioning rod 15. The moving plate 20 drives the square block 18 and the right-angle block 27 to move, so that the square block 18 enters the square hole 14 and the right-angle block 27 passes through the square hole 14 and is placed at the right end of the round plate 12. Then, the latching block 23 is released, and the positioning block 26 is pushed into the positioning hole 17 by the spring 25 to fix the position of the right-angle block 27.
[0032] The electric telescopic rod 37 drives the limiting block 36 to move and contact the right end face of the circular plate 12. When the carton is flipped, the control motor 40 drives the gear 39 to rotate. The gear 39 meshes with the ring rack 13 to drive the circular plate 12 to rotate. The circular plate 12 drives the carton to rotate and flip through the rotating rod 9 and the support frame 11. At the same time, the circular plate 12 drives several right-angle blocks 27 to rotate. When the extended right-angle block 27 moves to the position of the limiting block 36, the limiting block 36 will first squeeze the trigger block 35. The trigger block 35 is squeezed into the hidden groove 29. At the same time, the trigger block 35 pushes the sliding plate 31 to move through the connecting block 34. The sliding plate 31 moves and compresses the spring 32. At the same time, the sliding plate 31 presses the trigger switch 33. The trigger switch 33 controls the motor 40 to stop working. The motor 36 stops the rotating rod 9 from rotating. At the same time, the right-angle block 27 is blocked by the limit block 36 to prevent the right-angle block 27 from rotating too far, so that the carton can be stably facing upwards. After one side of the carton is attached, the electric telescopic rod 37 moves and drives the limit block 36 to move away from the right-angle block 27. Then, the motor 40 drives the right-angle block 27 to rotate away from the limit block 36. After the right-angle block 27 rotates away, the electric telescopic rod 37 drives the limit block 36 to quickly reset and contact the circular plate 12. Then, the next limiting operation is performed. After the carton is attached, the electric telescopic rod 41 pushes the return push plate 42 to move. The return push plate 42 pushes the carton outside the support frame 11, so that the carton can fall stably onto the conveyor belt for transmission without the carton tipping over.
