[0002] Automatic steering technology for corrugated boxes has been widely used in modern logistics and packaging industries, especially in automated sorting and transportation systems. This technology uses rolling friction to enable corrugated boxes to flexibly turn on the production line or conveyor belt, thereby improving work efficiency. With the rapid development of e-commerce, the demand for efficient and accurate packaging and transportation is increasing. Companies have adopted automatic steering equipment to reduce manual intervention and improve the level of production automation. The design of automatic steering equipment has been continuously optimized, using high-strength materials and advanced control systems to ensure stability and reliability in different environments.

[0003] In practice, traditional corrugated carton automatic steering equipment typically uses rolling friction to drive carton steering. This method works well for standard corrugated cartons, but it faces challenges with large corrugated cartons. Due to their heavy weight and low rigidity, rolling friction can easily damage the bottom of large cartons. Especially during steering, friction can cause the bottom of the carton to deform or crack, affecting its load-bearing capacity and appearance. Damage to the bottom can also lead to leakage or damage during subsequent transportation, making it unsuitable for practical applications. Summary of the Invention

The two sides of the second mobile frame 25 are respectively fixedly connected to the lifting motor 32, and one end of the output shaft of the lifting motor 32 is fixedly connected to the threaded rod 31.

[0036] One end of the threaded rod 31 is threadedly connected to the lifting block 30, and a motion motor is arranged inside the lifting block 30.

A first gear 26 is connected to one end of the output shaft of the linear motor 27, and the first gear 26 is engaged with the linear rack 21.

[0038] In this embodiment, the conveying motor 6 is started to drive the multiple first conveying rollers 7 to rotate, thereby driving the first conveyor belt 8 to convey forward, and through the cooperation of the first pulley 2, the second pulley 3, the belt 4 and the third pulley 5, the auxiliary belt 16 and the second conveyor belt 10 are respectively driven forward to convey, and the second conveyor belt 10 drives the corrugated cardboard box to move forward. Through the conveying action of the auxiliary belt 16 and the intermediate belt 18, the corrugated cardboard box is located directly above the closing plate 9, and the two support plates 33 on the linear motion mechanism and the arc motion mechanism are both located at the bottom of the corrugated cardboard box. The camera recognizes that the position of the corrugated cardboard box is directly above the closing plate 9, stops the rotation of the auxiliary belt 16 and the intermediate belt 18, and makes the corrugated cardboard box stay directly above the two support plates 33.

[0039] Furthermore, the support plate 33 and the corrugated cardboard box are raised by starting the electric telescopic rod 35, and the lifting motor 32 is started to drive the lifting block 30 and the second gear 28 to move downward through the threaded rod 31, so that the second gear 28 is engaged with the arc rack 24 on one side of the triangular slide rail 23, and the second gear 28 is driven by the motion motor to move on the arc rack 24, thereby driving the second movable frame 25 and one end of the corrugated cardboard box to move toward one side of the shell 1, and the linear motor 27 is started to drive the first gear 26 to move on the linear rack 21 toward the other side of the shell 1, thereby driving one end of the corrugated cardboard box to move toward the other side of the shell 1, until the first movable frame 22 and the second movable frame 25 move to the two ends of the triangular slide rail 23 respectively.

[0040] Among them, the corrugated cardboard box is placed on the upper surface of the first conveyor belt 8 and the intermediate belt 18 through the electric telescopic rod 35 and the support plate 33, the position of the corrugated cardboard box is turned ninety degrees, and the large corrugated cardboard box is conveyed forward through the first conveyor belt 8, which has the effect of turning the position of the large corrugated cardboard box ninety degrees in a frictionless manner.

[0041] The camera identifies whether the position of the corrugated box is turned successfully. If successful, it will continue to prepare for the turning of the next corrugated box. Otherwise, the conveying motor 6, the flip motor 12, the linear motor 27 and the lifting motor 32 will be stopped.

[0042] In this embodiment, when it is necessary to turn the large corrugated cardboard box to the other side, similarly, the lifting motor 32 on the other side of the second movable frame 25 is started, and the lifting block 30 and the second gear 28 are driven downward by the threaded rod 31, so that the second gear 28 is engaged with the arc-shaped rack 24 on the other side of the triangular slide rail 23, and the second gear 28 is driven by the motion motor to move on the arc-shaped rack 24, thereby driving the second movable frame 25 and one end of the corrugated cardboard box to move to the other side of the shell 1, thereby achieving the effect of turning the large corrugated cardboard box in two directions.

[0043] Furthermore, when the electric telescopic rod 35 and the support plate 33 are used to lift a large corrugated cardboard box, the elastic force of the stabilizing spring 34 keeps the support plate 33 and the electric telescopic rod 35 in a tensioned state at all times, thereby making the lifting of the large corrugated cardboard box more stable.

[0044] Reference Figure 1 、 Figure 2 、 Figure 7 and Figure 8 In a preferred embodiment, the stacking mechanism includes a flip motor 12 fixedly connected to one side of the protective shell 11, a flip plate 15 at one end of the output shaft of the flip motor 12, two insertion rods 41 slidingly connected to one side of the flip plate 15, one end of the insertion rod 41 is aligned with the plate 14, and one end of the insertion rod 41 is located between the alignment plate 14 and the flip plate 15 and a buffer spring 40 is provided.

[0045] One side of the alignment plate 14 is fixedly connected to an extrusion rod 38, one end of the extrusion rod 38 is rotatably connected to two push rods 39, the other end of the push rod 39 is rotatably connected to the intermediate rod 36, and the two side edges of the alignment plate 14 are rotatably connected to the extrusion plates 37, and the extrusion plates 37 and the intermediate rods 36 are rotatably connected.

[0046] In this embodiment, multiple corrugated cardboard boxes are stacked together by stacking them on the upper surface of the second conveyor belt 10, and the flip motor 12 is started to drive the flip plate 15 and the alignment plate 14 to rotate, so that the flip plate 15 and the alignment plate 14 are rotated from a horizontal position to a vertical position. The second conveyor roller 13 continuously rotates to drive the second conveyor belt 10 to continuously convey the corrugated cardboard boxes forward. The alignment plate 14 blocks the front and rear alignment of the corrugated cardboard boxes, and the left and right sides of the corrugated cardboard boxes are not yet aligned.

[0047] Furthermore, the corrugated cardboard box squeezes the alignment plate 14 and the insertion rod 41, thereby squeezing the buffer spring 40 to push the two push rods 39 to move through the squeezing rod 38, and the squeezing plates 37 on both sides are pushed to rotate ninety degrees through the connection action of the middle rod 36. The two squeezing plates 37 squeeze the left and right sides of the corrugated cardboard box respectively, so that the two sides of the stacked corrugated cardboard box group are also aligned, which has the effect of aligning the four sides of the corrugated cardboard box stacking. By reversing the flip motor 12, the flip plate 15 and the alignment plate 14 are rotated from the vertical position to the horizontal position.

[0048] Working principle: When in use, the conveying motor 6 is started to drive the multiple first conveying rollers 7 to rotate, thereby driving the first conveyor belt 8 to convey forward, and through the cooperation of the first pulley 2, the second pulley 3, the belt 4 and the third pulley 5, the auxiliary belt 16 and the second conveyor belt 10 are driven to convey forward respectively. By stacking the corrugated cardboard boxes on the upper surface of the second conveyor belt 10, multiple corrugated cardboard boxes are stacked together, and the flip motor 12 is started to drive the flip plate 15 and the alignment plate 14 to rotate, so that the flip plate 15 and the alignment plate 14 are rotated from the horizontal position to the vertical position. The second conveying roller 13 rotates continuously to drive the second conveyor belt 10 to continuously convey the corrugated cardboard boxes forward. The alignment plate 14 blocks the front and back alignment of the corrugated cardboard boxes. The left and right sides of the corrugated cardboard boxes are not aligned yet, and the corrugated cardboard boxes squeeze the alignment plate 14 and the insertion rod 41.Thus, the squeezing buffer spring 40 pushes the two push rods 39 to move through the squeezing rod 38, and the squeezing plates 37 on both sides are pushed to rotate ninety degrees through the connection of the middle rod 36. The two squeezing plates 37 squeeze the left and right sides of the corrugated cardboard box respectively, so that the two sides of the corrugated cardboard box group stacked together are also aligned, which has the effect of aligning the four sides of the corrugated cardboard box stacking. By reversing the flip motor 12, the flip plate 15 and the alignment plate 14 are rotated from the vertical position to the horizontal position. At this time, the second conveyor belt 10 drives the corrugated cardboard box to move forward. Through the transmission effect of the auxiliary belt 16 and the middle belt 18, the corrugated cardboard box is located just above the closing plate 9. The linear motion mechanism and the arc motion mechanism The two support plates 33 on the upper portion are both located at the bottom of the corrugated cardboard box. The camera recognizes that the position of the corrugated cardboard box is directly above the closing plate 9, stops the rotation of the auxiliary belt 16 and the middle belt 18, and makes the corrugated cardboard box stay directly above the two support plates 33. The support plates 33 and the corrugated cardboard box are raised by starting the electric telescopic rod 35, and the lifting motor 32 is started to drive the lifting block 30 and the second gear 28 to move downward through the threaded rod 31, so that the second gear 28 is engaged with the arc-shaped rack 24 on one side of the triangular slide rail 23, and the second gear 28 is driven by the motion motor to move on the arc-shaped rack 24, thereby driving the second mobile frame 25 and one end of the corrugated cardboard box to move toward one side of the shell 1, and starting The linear motor 27 drives the first gear 26 to move on the linear rack 21 to the other side of the shell 1, thereby driving one end of the corrugated cardboard box to move to the other side of the shell 1, until the first movable frame 22 and the second movable frame 25 move to the two ends of the triangular slide rail 23 respectively, and the corrugated cardboard box is placed on the upper surface of the first conveyor belt 8 and the middle belt 18 through the electric telescopic rod 35 and the support plate 33, and the position of the corrugated cardboard box is turned ninety degrees. The large corrugated cardboard box is conveyed forward by the first conveyor belt 8, which has the effect of turning the position of the large corrugated cardboard box ninety degrees in a frictionless manner. When the large corrugated cardboard box needs to be turned to the other side, similarly, the second movable frame 25 is started to move to the other side. The lifting motor 32 on one side, via the threaded rod 31, drives the lifting block 30 and the second gear 28 downward, causing the second gear 28 to mesh with the arcuate rack 24 on the other side of the triangular slide rail 23. The motion motor drives the second gear 28 to move on the arcuate rack 24, thereby driving the second movable frame 25 and one end of the corrugated cardboard box toward the other side of the housing 1, thus achieving the effect of turning the large corrugated cardboard box in two directions. When using the electric telescopic rod 35 and support plate 33 to lift a large corrugated cardboard box, the elastic force of the stabilizing spring 34 keeps the support plate 33 and the electric telescopic rod 35 in a state of tension at all times, achieving a more stable lifting effect for the large corrugated cardboard box.
