[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 4In an embodiment of the utility model, a flip structure for printing on a packaging box comprises two side panels 1, transmission rollers 2 are rotatably installed at both ends of the inner sides between the two side panels 1, the two transmission rollers 2 are connected by a transmission belt 3, and there is a gap between the two transmission belts 3. An intermittent rotation mechanism is installed at one end of one side panel 1, and a round roller 4 rotatably connected to the side panel 1 is installed at the output end of the intermittent rotation mechanism. A flip mechanism is circumferentially installed on the outer wall of the round roller 4, and a rotating wheel 10 is rotatably installed at the end of the flip mechanism away from the round roller 4.

[0020] In this embodiment: first, by starting the servo motor connected to one end of a transmission roller 2, the servo motor drives one transmission roller 2 to rotate, and the transmission roller 2 drives another transmission roller 2 to rotate through the transmission belt 3. At this time, the transmission belt 3 can drive the packaging box placed on its surface to move synchronously, and the printed surface on one side of the packaging box moves to the front end of the flip mechanism. At this time, the intermittent rotation mechanism in the running state starts the flip mechanism to rotate 90 degrees once. At this time, the packaging box is flipped 90 degrees, and the other side of the packaging box can be printed. Similarly, multiple intermittent rotation mechanisms and flip mechanisms can be set to achieve auxiliary flip printing on the four sides of the cubic packaging box, or by the cooperation of two sets of intermittent rotation mechanisms and flip mechanisms, the packaging box can be flipped 180 degrees, and corresponding information can be printed on the two opening surfaces of the packaging box.

[0021] During the flipping process of the flipping mechanism, if there are many boxes to be printed, one end of the rotating flipping mechanism will come into contact with the surface of the box, causing scratches on the surface of the box. Therefore, the above situation can be avoided by adding a rotating wheel 10.

[0022] Please refer to Figure 1 The intermittent rotation mechanism includes a driven gear 5 connected to one end of the round roller 4 through a coupling. The driven gear 5 is located on the outside of a side plate 1. The outside of the driven gear 5 is meshed with a driving gear 7. A rotating motor 6 is installed on the outside of one side plate 1 through a mounting bracket. The output shaft of the rotating motor 6 is coaxially connected to the driving gear 7 through a coupling.

[0023] In this embodiment, by starting the rotary motor 6, the rotary motor 6 drives the driving gear 7 at its output end to rotate. When the rotating driving gear 7 is engaged with the driven gear 5, the driven gear 5 rotates ninety degrees. The rotation of the driven gear 5 drives the round roller 4 to rotate ninety degrees. The round roller 4 can drive the flip mechanism to rotate ninety degrees, thereby achieving the purpose of flipping the packaging box ninety degrees.

[0024] Please refer to Figure 1The flap mechanism includes a fixed flap 8 fixedly connected to the outer periphery of the round roller 4. An inwardly recessed sliding cavity 12 is provided at one end of the fixed flap 8 away from the round roller 4. The inner wall of the sliding cavity 12 is slidably connected to a sliding plate 13 that passes through the outside of the fixed flap 8. The end of the sliding plate 13 located outside the fixed flap 8 is fixedly connected to an adjusting flap 9.

[0025] In this embodiment: when flipping packaging boxes of different sizes, the flip plate 9 is adjusted by pulling or pushing the flip plate 9, which drives the sliding plate 13 to slide in the sliding cavity 12, thereby adjusting the overlapping area of ​​the sliding plate 13 and the sliding cavity 12, changing the overall length of the flip mechanism, and avoiding the situation where the length of the flip mechanism is greater than the length of the packaging box to be flipped, thereby avoiding the flip mechanism from causing the next adjacent packaging box to tilt up when the flip mechanism rotates, or driving two packaging boxes to flip at the same time, and the next adjacent packaging box to slide down due to the tilt during the rotation process, especially during the rotation process from a high point to a low point, resulting in an uncontrollable flipping surface.

[0026] Please refer to Figure 4 A screw hole 11 is provided on one side of the fixed flap 8 and penetrates into the inner cavity of the sliding cavity 12. The inner wall of the screw hole 11 is threadedly connected with a locking bolt, and the end of the locking bolt in the tightened state is used to abut against one side of the sliding plate 13.

[0027] In this embodiment: after the sliding plate 13 has finished sliding in the sliding cavity 12, a bolt is used to threadably connect it to the screw hole 11, and one end of the tightened bolt is tightly pressed against the surface of the sliding plate 13, thereby limiting the position of the sliding plate 13 and preventing the sliding plate 13 from sliding freely.

[0028] Please refer to Figure 4 The inner wall of the sliding cavity 12 is a "convex" structure, and the sliding plate 13 is located at one end of the inner wall of the sliding cavity 12 and is integrally formed with an anti-slip portion, the width of the anti-slip portion is equal to the width of the wide part of the inner wall of the sliding cavity 12.

[0029] In this embodiment, the above-mentioned design can prevent the sliding plate 13 from being completely separated from the sliding cavity 12, thereby playing a role of limiting.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
