Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-6 A cartoning machine flap folding block structure for improving work efficiency includes a mounting plate 1. Two connecting shafts 2 are rotatably connected to the upper end of the mounting plate 1. An L-shaped plate 3 is fixedly connected to the upper end of the mounting plate 1. The upper ends of the two connecting shafts 2 pass through the L-shaped plate 3 and are fixedly connected to a first swing block 4. A motor 5, which is a servo motor, is mounted on the lower end of the mounting plate 1. The end of the output shaft of the motor 5 passes through the mounting plate 1 and is fixedly connected to one of the connecting shafts 2. A cam 6 is fixedly connected to the outer wall of one of the connecting shafts 2. A second swing block 7 is provided on the upper end of the mounting plate 1. One end of the second swing block 7 is hinged to the upper end of the mounting plate 1, and the other end of the second swing block 7 is hinged to a front flap mechanism. The front flap mechanism is existing technology and will not be described in detail here. The cam 6 and the second swing block 7 cooperate with each other to convert the circular motion of the connecting shaft 2 into the swing motion of the second swing block 7. This conversion of motion provides suitable power and motion mode for the front flap mechanism, which helps to complete the flap insertion action in the cartoning process.

[0024] In this design, transmission wheels 8 are fixedly connected to the outer walls of both connecting shafts 2. The two transmission wheels 8 are connected by a belt 9. The motor 5 drives one of the connecting shafts 2 to rotate. The two connecting shafts 2 are connected by transmission wheels 8 and belt 9. This design ensures that the power is transmitted to each component stably and efficiently, so that the entire flap rocker block structure operates in a coordinated manner, thereby improving the efficiency of the boxing operation. The upper ends of the two first swing blocks 4 are rotatably connected to rotating shafts 10. The upper ends of the two rotating shafts 10 are fixedly connected to a fixing plate 11. The two rotating shafts 10 slide together on a common plate. A sliding plate 12 is movably connected, and a first threaded rod 13 is rotatably connected to the lower end of a fixed plate 11. The first threaded rod 13 is threadedly connected to the sliding plate 12, and the upper end of the first threaded rod 13 passes through the fixed plate 11 and is fixedly connected to a first knob 14. By rotating the first knob 14, the first threaded rod 13 is rotated, causing the sliding plate 12 to slide up and down along the rotating shaft 10, thereby adjusting the height of the rear folding tongue plate 17 and the insert tongue plate 18 to adapt to packaging boxes of different sizes and specifications, enhancing the versatility and adaptability of the cartoning machine. A rubber layer is provided on the first knob 14.

[0025] The sliding plate 12 has two moving slots 15, each containing a moving plate 16. One end of one moving plate 16 is fixedly connected to a rear flap plate 17, and the other end is fixedly connected to a tongue plate 18. Adjusting slots 19 are provided on opposite sides of the two moving slots 15. Sleeves 20 are fixedly connected to the inner walls of both adjusting slots 19. Second threaded rods 21 are threadedly connected to the inner walls of both sleeves 20. The opposite ends of the two second threaded rods 21 are fixedly connected to… Each of the two movable plates 16 has a limit block 22 and multiple limit grooves 23 that cooperate with the corresponding limit block 22 on opposite sides. The opposite ends of the two second threaded rods 21 extend to the outside and are fixedly connected to a second knob 24. By rotating the second knob 24, the second threaded rods 21 are rotated, so that the limit block 22 cooperates with different limit grooves 23, thereby realizing the adjustment of the position of the rear folding tongue plate 17 and the insert tongue plate 18, thereby improving the quality and accuracy of the box. Both second knobs 24 are provided with a rubber layer.

[0026] In this utility model, when in use, the motor 5 is started, which drives the connecting shaft 2 fixedly connected to it to rotate. Since the outer walls of the two connecting shafts 2 are fixedly connected with transmission wheels 8, and the two transmission wheels 8 are connected by a belt 9, the rotation of one connecting shaft 2 will drive the other connecting shaft 2 to rotate synchronously. In this way, the power is transmitted between the two connecting shafts 2, providing a power source for the entire folding tongue swing block structure.

[0027] When it is necessary to adjust the height of the rear flap 17 and the insert flap 18, turn the first knob 14 to drive the first threaded rod 13 fixedly connected to it to rotate. The rotation of the first threaded rod 13 will cause the sliding plate 12 to slide up and down along the rotating shaft 10. In this way, the sliding plate 12 moves up and down with the rear flap 17 and the insert flap 18 through the moving plate 16 to adapt to packaging boxes of different heights and realize the height adjustment.

[0028] When it is necessary to adjust the position of the rear folding tongue plate 17 and the inserting tongue plate 18, turn the second knob 24 to drive the second threaded rod 21 fixedly connected to it to rotate. The second threaded rod 21 rotates in the sleeve 20, causing the limiting block 22 to move into the corresponding limiting groove 23. In this way, the position of the moving plate 16 in the moving groove 15 can be restricted, thereby realizing the adjustment of the position of the rear folding tongue plate 17 and the inserting tongue plate 18, ensuring that the folding tongue and inserting tongue actions can accurately act on the corresponding positions of the packaging box.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
