[0025] The first adjustment mechanism includes a first bevel gear 19 fixedly connected to the top ends of the two movable shafts 18, the top outer wall of the limit frame 3 is rotatably connected to the two spline shafts 15 through the shaft seat 14, the outer walls of the two relatively far sliders 8 are fixedly connected to the fixing frame 20, the outer wall of the fixing frame 20 is rotatably connected to the second bevel gear 21, the middle outer wall of the second bevel gear 21 is provided with a spline groove 22, the two second bevel gears 21 are mounted on the outer walls of the two spline shafts 15 through the spline groove 22, and the spline shaft 15 passes through the fixing frame 20, the second bevel gear 21 is meshed with the first bevel gear 19, and the servo motor 16 is fixedly installed on the outer wall of the top middle section of the limit frame 3, and the output shafts at both ends of the servo motor 16 are fixedly connected to the ends of the two spline shafts 15 away from the shaft seat 14.

[0026] A sliding groove 17 is symmetrically provided on the middle outer wall of the top of the limiting frame 3 , and the top end of the movable shaft 18 passes through the sliding groove 17 .

[0027] The second adjustment mechanism includes a gear 11 rotatably connected to the middle outer wall at the bottom of the limiting frame 3 , and a rack 12 is fixedly connected to the top outer walls of the two moving plates 9 , and the two racks 12 are meshed with the gear 11 .

[0028] An electric cylinder 13 is fixedly mounted on the bottom outer wall of the limiting frame 3 , and an output end of the electric cylinder 13 is fixedly connected to the top outer wall of a movable plate 9 .

[0029] A cylinder 4 is fixedly mounted on the top outer wall of the mounting frame 2 . The output end of the cylinder 4 passes through the mounting frame 2 and is welded with a connecting piece 5 . The connecting piece 5 is welded to the top outer wall of the limiting frame 3 .

[0030] A plurality of supporting legs 6 are fixedly connected to the bottom outer wall of the conveyor belt 1 .

[0031] The implementation principle of the packaging carton creasing mechanism of the embodiment of the present application is as follows: in actual use, the cardboard to be creasing is placed on the conveyor belt 1, and the conveyor belt 1 conveys the cardboard. When the cardboard moves to the bottom of the two creasing plates 10, the cylinder 4 is started, and its output end drives the limit frame 3 to descend through the connecting piece 5, and then drives the two creasing plates 10 to creasing the cardboard;

[0032] When the length between two indentations needs to be adjusted, the electric cylinder 13 can be started through the second adjustment mechanism. When the output end of the electric cylinder 13 is extended, the movable plate 9 will be pushed outward to move. When one movable plate 9 moves outward, it will drive one electric cylinder 13 to move outward. One electric cylinder 13 will drive the gear 11 meshed with it to rotate. When the gear 11 rotates, it will drive another electric cylinder 13 meshed with it to move relatively outward. At this time, the two electric cylinders 13 synchronously push the two movable plates 9 outward to move. The two movable plates 9 drive the two indentation plates 10 to move away from each other, thereby increasing the distance between the indentations.

[0033] Similarly, when the output end of the electric cylinder 13 contracts, it will pull a moving plate 9 inward. At this time, through the cooperation between the rack 12 and the gear 11, the two moving plates 9 move inward relative to each other, and then the two indentation plates 10 are brought closer to each other, reducing the distance between the indentations. It is worth noting that when the two moving plates 9 move, they will drive multiple sliders 8 to slide on the outer walls of the two guide rails 7, which plays a limiting role, so that the two moving plates 9 always move linearly, increasing the stability of movement;

[0034] When the horizontal angles of the two indentations need to be adjusted, the servo motor 16 can be started through the adjustment mechanism 1, and the output shafts at both ends of the servo motor 16 drive the two spline shafts 15 to rotate in the shaft seat 14, and the two second bevel gears 21 can be driven to rotate through the spline shaft 15, and the two second bevel gears 21 drive the first bevel gears 19 meshing therewith to rotate, and the first bevel gear 19 drives the indentation plate 10 to rotate through the movable shaft 18. When the indentation plate 10 rotates, the horizontal angles of the two indentations can be adjusted synchronously;

[0035] It is worth noting that, through an external controller, the start and stop, speed, step angle and other parameters of the servo motor 16 can be accurately controlled, so as to realize accurate control of the horizontal rotation angle of the two indentation plates 10, and when the two movable plates 9 are adjusting the spacing, the two fixed frames 20 will always follow the movable plates 9 to move through the slider 8, so that the rotating second bevel gear 21 on the fixed frame 20 is always engaged with the first bevel gear 19, and when the fixed frame 20 moves, it will drive the second bevel gear 21 to move, and the second bevel gear 21 can be driven to rotate by the spline shaft 15 while sliding on the outer wall of the spline shaft 15 through the spline groove 22 inside it, and then can cooperate with the movement of the two movable plates 9 to adjust the position of the second bevel gear 21 on the outer wall of the spline shaft 15.
