Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Please refer to Figures 1-6 An automatic creasing and slotting machine for cardboard boxes is disclosed. Its structure includes a frame 1, a motor unit 2, a placement box 3, a limiting device 4, and a slotting device 5. The motor unit 2 is installed inside the frame 1. The placement box 3, which can place cardboard boxes, is installed on the top of the frame 1. The front end of the placement box 3 is provided with the limiting device 4 and the slotting device 5 located on the frame 1. Two sets of limiting devices 4 are symmetrically arranged and installed on both sides of the slotting device 5.

[0020] In this embodiment, the frame 1 includes a conveyor belt 11 and a pusher block 12. The conveyor belt 11 is located on the workbench of the frame 1 and is connected to the output end of the motor unit 2. The motor unit 2 can drive the conveyor belt 11 to move and transport the cartons. The pusher block 12 is fixed on the conveyor belt 11. The height of the pusher block 12 is greater than the thickness of the cartons. As the conveyor belt 11 moves, it can push out the cartons stacked in the placement box 3 in sequence for creasing and grooving.

[0021] In this embodiment, both ends of the bottom of the placement box 3 are provided with opening slots, and the height of the opening slots is greater than the height of the push block 12. This allows the push block 12 to contact the bottommost carton during transport, pushing the cartons out of the placement box 3 one by one for slotting processing, thereby improving efficiency.

[0022] In this embodiment, the limiting device 4 includes a cylinder 41, a rack 42, a half-tooth gear 43, a swing rod 44, a push rod 45, and a limiting block 46. The cylinder 41 is located on the frame 1. The piston end of the cylinder 41 is connected to the rack 42, which can drive the rack 42 to move back and forth on the frame 1. One side of the rack 42 is meshed with the half-tooth gear 43. The bottom of the half-tooth gear 43 is fixed with the swing rod 44. One side of the swing rod 44 is rotatably engaged with the push rod 45 through a rotating shaft. The other end of the push rod 45 is connected to the limiting block 46. The limiting block 46 is located on the frame 1 and is rotatably engaged with the frame 1 through a main shaft. The push rod 45 can drive the limiting block 46 to rotate on the frame 1. Three sets of push rods 45 and limiting blocks 46 are equidistantly arranged.

[0023] In this embodiment, the piston rod of the cylinder 41 drives the rack 42 to move back and forth. With the help of the gear meshing between the rack 42 and the half gear 43, the half gear 43 will rotate in both directions during the movement. When the half gear 43 rotates forward, the swing rod 44 will move backward and drive the limiting block 46 to rotate backward through the push rod 45, thereby increasing the distance between the two sets of limiting devices 4. This allows the limiting device 4 to limit the position of the carton paperboard of different widths during the movement and conveying, and can prevent the carton from deviating during the conveying.

[0024] In this embodiment, the limiting block 46 is a structure with a protruding lower end. The protrusion contacts the carton to limit the position of the carton.

[0025] In this embodiment, the grooving device 5 includes a bearing seat 51, a main shaft 52, a motor 53, a retaining ring 54, and a grooving wheel 55. The bearing seats 51 are symmetrically arranged on the frame 1. Several main shafts 52 are installed between the bearing seats 51. One side of each main shaft 52 is connected to the motor 53 on the bearing seat 51 and can be driven by the motor 53. Several retaining rings 54 are installed on the main shafts 52. A grooving wheel 55 is installed between every two sets of retaining rings 54. The grooving wheel 55 is rotated by the main shaft 52, and the grooving wheel 55 is used to groov the carton.

[0026] In this embodiment, the fixing ring 54 includes an upper ring 541, a lower ring 542, an N-pole magnet 543, an S-pole magnet 544, an insert block 545, a convex ball 546, and an insert groove 547. The fixing ring 54 is composed of an upper ring 541 and a lower ring 542, which are rotatably engaged. An N-pole magnet 543 is installed at one end of the upper ring 541, and an S-pole magnet 544 is installed at one end of the lower ring 542. An insert block 545 is fixed to the top of the N-pole magnet 543. Convex balls 546 are provided on both sides of the insert block 545. An insert groove 547 is provided inside one end of the lower ring 542. The insert groove 547 is movably engaged with the insert block 545. The convex ball 546 is made of soft rubber, which can increase the friction between the insert block 545 and the insert groove 547.

[0027] In this embodiment, when the upper ring 541 and the lower ring 542 are combined, the N-pole magnet 543 and the S-pole magnet 544 will attract each other, thereby increasing the clamping force when the upper ring 541 and the lower ring 542 are combined. At this time, the fixing ring 54 and the main shaft 52 can fit tightly together to clamp and fix the position of the slotted wheel 55.

[0028] Working principle: When the carton is slotted on the slotting machine, the cardboard is stacked and placed inside the placement box 3. Then the drive motor 2 is turned on, and the motor 2 drives the conveyor belt 11 to move. As the conveyor belt 11 moves, the pusher 12 installed on it pushes the carton inside the placement box 3 out one by one. Under the conveying action of the conveyor belt 11, the carton is transported to the slotting device 5 for slotting and creasing processing. Meanwhile, the piston rod of the drive cylinder 41 drives the rack 42 to move back and forth. With the help of the rack 42 meshing with the half gear 43, the half gear 43 will rotate in both directions during the movement. When the half gear 43 rotates forward, the swing rod 44 will move backward and drive the limit block 46 to rotate backward through the push rod 45, thereby increasing the distance between the two sets of limit devices 4. When the half gear 43 rotates in reverse, the swing rod 44 will move forward and drive the limit block 46 to rotate forward through the push rod 45, thereby decreasing the distance between the two sets of limit devices 4. This can limit the position of the carton paperboard of different widths during the movement and conveying, and prevent the carton from deviating during the conveying process. Then, the grooving wheel 55 is rotated by the motor 53 to perform grooving on the carton. When the position of the grooving wheel 55 needs to be adjusted as needed, the insert block 545 of the upper ring 541 can be pulled out from the insert groove 547 of the lower ring 542 by applying outward pulling force on both sides of the fixing ring 54, thereby removing the fixing ring 54 from the main shaft 52, thus adjusting the position of the grooving wheel 55 quickly and conveniently, improving efficiency.
