Description

Technical Field

[0001] This application relates to the field of tobacco packaging equipment technology, and specifically to a carton flattening machine. Background Technology

[0002] In the tobacco processing line, after the cigarette packs are removed from the previous process, workers need to disassemble, flatten, and recycle the cardboard boxes. Flattening the cardboard boxes is an important unpacking step, used to fold the boxes and improve the convenience of subsequent handling and stacking.

[0003] The existing cardboard box flattening process involves manually flattening the boxes after the cigarette packs have been removed. Workers apply opposing forces to two opposite corners of the box to flatten it. This manual process is not only inefficient but also increases the workload for workers. Utility Model Content

[0011] The cardboard box is a cubic shape commonly found on the market. There are four side lines that are spaced apart on the four sides of the cardboard box. The cardboard box can be folded along two opposite side lines.

[0012] In one embodiment, a slide rail is laid on the first plane; the translation mechanism has a roller slidably connected to the slide rail, and a second drive motor is drivenly connected to the roller.

[0013] Specifically, the first driving component includes a second driving motor, a rotating shaft, and a driving wheel; the second driving motor is fixedly connected to the translation mechanism, the output end of the second driving motor is driven by the rotating shaft, the rotating shaft is rotatably connected to the translation mechanism, the driving wheel is fixedly connected to the rotating shaft, and the driving wheel abuts against the roller for transmission.

[0014] In one embodiment, the track body is a rack; the rack extends along the second plane; the second drive member includes a third drive motor fixedly connected to the lifting mechanism, the output end of the third drive motor having a gear that meshes with the rack.

[0015] In one embodiment, the first plane and the second plane are perpendicular, and the extension direction of the rail body is perpendicular to the extension direction of the slide rail.

[0016] In one embodiment, the translation mechanism includes a frame; the rollers are rotatably connected to the frame; the second drive motor is fixedly connected to the frame; and the rack is fixedly connected to the frame.

[0017] In one embodiment, the lifting mechanism includes a lifting plate; a third drive motor is fixedly connected to the upper end of the lifting plate; a first drive motor is fixedly connected to one side of the lifting plate; and a threaded rod is rotatably connected to the lower end of the lifting plate.

[0018] In one embodiment, the threaded rod has a first threaded segment and a second threaded segment, the first threaded segment and the second threaded segment having opposite thread directions; the first moving rod and the second moving rod are respectively threadedly engaged with the first threaded segment and the second threaded segment.

[0019] In one embodiment, there are two threaded rods connected by a coupling. The two threaded rods have opposite thread directions, and the first moving rod and the second moving rod are threadedly engaged with the two threaded rods respectively.

[0020] In one embodiment, the frame has two through holes, each with a strip-shaped cross-section; the first moving rod and the second moving rod are respectively inserted into the two through holes, and both the first moving rod and the second moving rod can move within the corresponding through holes.

[0021] Specifically, the strip-shaped through hole extends along the extension direction of the threaded rod.

A first drive motor then drives a threaded rod to rotate, causing the first and second moving rods to move apart. This stretches the two opposite side lines of the box, flattening it. The flattened box is then moved by a translation mechanism to the next-level gripping device for removal.

[0026] Flattening the carton using the first and second moving rods not only improves the efficiency of flattening the carton but also reduces the high labor load on workers caused by manual flattening.

[0027] The lifting mechanism can drive the lifting and lowering movement of the first and second moving rods. After the robotic arm fastens the carton above the first and second moving rods, the rising first and second moving rods abut against the bottom of the carton and push the carton board at the bottom of the carton open. Then, when the first and second moving rods move apart, the carton can be flattened more easily, reducing the impact of the carton board at the bottom of the carton on the sides of the carton.

[0042] This application proposes improvements and innovations, and presents the following embodiments.

[0043] In some implementations, please refer to Figures 1 to 5 A carton flattening machine is provided, comprising:

[0044] Translation mechanism 1, which can move on the first plane;

[0045] A first driving component 2 is used to drive the translation mechanism 1 to move; the first driving component 2 is fixedly connected to the translation mechanism 1.

[0046] Lifting mechanism 3, which can move on the second plane;

[0047] A second driving member 4 is used to drive the lifting mechanism 3 to move; the second driving member 4 is fixedly connected to the lifting mechanism 3; the translation mechanism 1 has a rail body 11 that is drivenly connected to the second driving member 4; the rail body 11 extends in a second plane, and the extension direction of the rail body 11 intersects with the first plane; the first plane and the second plane intersect at a predetermined angle.

[0048] The flattening mechanism 5 is fixedly connected to the lifting mechanism 3; the flattening mechanism 5 has a first moving rod 51 and a second moving rod 52 that can move towards or away from each other; the flattening mechanism 5 has a threaded rod 53 that is threadedly engaged with the first moving rod 51 and the second moving rod 52, and the threaded rod 53 is rotatably connected to the lifting mechanism 3; a first drive motor 54 that is drively connected to the threaded rod 53 is fixedly connected to the lifting mechanism 3.

[0049] The cardboard box is a cubic shape commonly found on the market. There are four side lines that are spaced apart on the four sides of the cardboard box. The cardboard box can be folded along two opposite side lines.

[0050] Workers or robotic arms fasten the cardboard box onto the first moving rod 51 and the second moving rod 52, causing the two opposite side lines of the cardboard box to abut against the first moving rod 51 and the second moving rod 52 respectively. The first drive motor 54 drives the threaded rod 53 to rotate, thereby causing the first moving rod 51 and the second moving rod 52 to move apart. The two opposite side lines of the cardboard box are stretched, thus flattening the box. The flattened cardboard box is then moved by the translation mechanism 1 to the next-level clamping device to be clamped out.

[0051] Flattening the carton by using the first moving rod 51 and the second moving rod 52 not only improves the efficiency of flattening the carton, but also reduces the high labor load on workers caused by manual flattening.

[0052] The lifting mechanism 3 can drive the lifting and lowering movement of the first moving rod 51 and the second moving rod 52. After the robotic arm fastens the carton above the first moving rod 51 and the second moving rod 52, the rising first moving rod 51 and the second moving rod 52 abut against the bottom of the carton and push the carton board located at the bottom of the carton open. Subsequently, when the first moving rod 51 and the second moving rod 52 move apart, the carton can be flattened more easily, reducing the impact of the carton board at the bottom of the carton on the sides of the carton.

[0053] In one embodiment, a slide rail 12 is laid on the first plane; the translation mechanism 1 has a roller 13 slidably connected to the slide rail 12, and a second drive motor 21 is drivenly connected to the roller 13. The cooperation between the slide rail 12 and the roller 13 makes the movement of the translation mechanism 1 smoother, and the translation mechanism 1 can only move along the slide rail 12 to a predetermined direction, which facilitates the lower-level equipment to clamp the flattened cardboard box.

[0054] Specifically, the first driving component 2 includes a second driving motor 21, a rotating shaft 22, and a driving wheel 23. The second driving motor 21 is fixedly connected to the translation mechanism 1, and its output end is driven by the rotating shaft 22. The rotating shaft 22 is rotatably connected to the translation mechanism 1. The driving wheel 23 is fixedly connected to the rotating shaft 22 and abuts against the roller 13 for transmission. The roller 13 is driven by the cooperation of the rotating shaft 22 and the driving wheel 23. The design is reasonable, the structure is simple, and the use is reliable.

[0055] In one embodiment, the rail body 11 is a rack; the rack extends along a second plane; the second driving member 4 includes a third driving motor 41 fixedly connected to the lifting mechanism 3, and the output end of the third driving motor 41 has a gear 42 that meshes with the rack. The lifting function of the lifting mechanism 3 is achieved by the meshing of the gear 42 and the rack, which is reasonably designed and has a simple structure.

[0056] In one embodiment, the first plane and the second plane are perpendicular, and the extension direction of the rail 11 is perpendicular to the extension direction of the slide rail 12. The perpendicularity of the first plane and the second plane enables the carton to be flattened in the vertical plane and moved in the horizontal plane, which is a reasonable design and simple structure.

[0057] In one embodiment, the translation mechanism 1 includes a frame 14; rollers 13 are rotatably connected to the frame 14, a second drive motor 21 is fixedly connected to the frame 14, and a rack is fixedly connected to the frame 14. The frame 14 allows for better installation of other components.

[0058] In one embodiment, the lifting mechanism 3 includes a lifting plate 31; a third drive motor 41 is fixedly connected to the upper end of the lifting plate 31; a first drive motor 54 is fixedly connected to one side of the lifting plate 31; and a threaded rod 53 is rotatably connected to the lower end of the lifting plate 31. The lifting plate 31 provides sufficient mounting space for the threaded rod 53 and the third drive motor 41.

[0059] In one embodiment, the threaded rod 53 has a first threaded section 531 and a second threaded section 532, with the threads of the first threaded section 531 and the second threaded section 532 having opposite directions of rotation; the first moving rod 51 and the second moving rod 52 are respectively threadedly engaged with the first threaded section 531 and the second threaded section 532. When the threaded rod 53 rotates, the first moving rod 51 and the second moving rod 52 can move towards each other or away from each other.

[0060] In one embodiment, there are two threaded rods 53, which are connected by a coupling 55. The threads of the two threaded rods 53 have opposite directions, and the first moving rod 51 and the second moving rod 52 are threadedly engaged with the two threaded rods 53 respectively. Using two threaded rods 53 facilitates the installation or replacement of one of the threaded rods 53.

[0061] In one embodiment, the frame 14 has two through holes 15, each with a strip-shaped cross-section; the first moving rod 51 and the second moving rod 52 are respectively inserted into the two through holes 15, and both the first moving rod 51 and the second moving rod 52 can move within their respective through holes 15. The through holes 15 effectively restrict the first moving rod 51 and the second moving rod 52 to move only within the through holes 15, preventing them from rotating relative to the through holes 15.

[0062] Specifically, the strip-shaped through hole 15 extends along the extension direction of the threaded rod 53.

[0063] In one embodiment, there are two slide rails 12 spaced apart from each other, and multiple rollers 13 arranged alternately and evenly distributed on the two slide rails 12; there are two racks spaced apart from each other; the output end of the third drive motor 41 is connected to the drive rod 43, and two gears 42 are fixedly connected to the drive rod 43, with each gear 42 meshing with one of the two racks. The design of the two slide rails 12 and the two racks ensures uniform force distribution, and the design is reasonable.

[0064] Specifically, the output end of the third drive motor 41 is connected to the drive rod 43 via a gearbox 44. The gearbox 44 allows for changes in the mounting position of the third drive motor 41 and also alters the output speed of the third drive motor 41, achieving appropriate lifting and lowering speeds.

[0065] The above are merely optional embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of this utility model.
