[0030] Please see Figures 1-4 As shown, this utility model has the following two specific embodiments.

[0031] Example 1

[0032] This utility model relates to a creasing mechanism for packaging cartons, comprising a conveying assembly 1 and a creasing assembly 2. The conveying assembly 1 is used to convey cardboard to a position below the creasing assembly 2, and the creasing assembly 2 is mounted above the conveying assembly 1 for creasing the cardboard. The creasing assembly 2 includes:

[0033] Support frame 21 is fixedly connected above the conveying assembly 1, and an electric push rod 211 is fixedly connected to the top of the support frame 21.

[0034] Pressure plate 22 is fixedly connected to the bottom output end of electric push rod 211, and several indentation knives 221 are provided at the bottom of pressure plate 22.

[0035] Pin 222 is fixedly connected to the top of the indentation knife 221. Several insertion holes 223 are opened at the bottom of the pressure plate 22. The inner wall of the insertion hole 223 is inserted into the outer surface of the pin 222.

[0036] Angle positioning block 224 is fixedly connected to the outer surface of pin 222. Angle positioning grooves 225 are provided in four directions on the inner wall of the insertion hole 223. The inner wall of the angle positioning grooves 225 is inserted into the outer surface of the angle positioning block 224.

[0037] Several magnetic snaps 226 are fixedly connected to the inner wall of the socket 223 and the top of the pin 222 respectively.

[0038] like Figures 1-3 As shown, by setting the indentation assembly 2, specifically by installing the indentation knife 221 according to the required indentation line pattern, aligning the pin 222 with the insertion hole 223 and inserting it, while ensuring that the angle positioning block 224 can be accurately embedded in the angle positioning groove 225, the magnetic buckle 226 on the top of the pin 222 and the magnetic buckle 226 on the inner wall of the insertion hole 223 attract each other, thereby installing the indentation knife 221 on the pressure plate 22. Multiple indentation knives 221 work together to meet the needs of different indentation patterns, improving the flexibility and versatility of the equipment.

[0039] Two limiting rods 212 are fixedly connected to the top of the pressure plate 22, and the outer surface of the limiting rods 212 is slidably connected to the top of the support frame 21.

[0040] Both sides of the bottom of the pressure plate 22, near the indentation knife 221, are fixedly connected to the sponge pads 23 by adhesive bonding.

[0041] The limiting rod 212 can provide guidance and limit for the lifting and lowering movement of the pressure plate 22, preventing the pressure plate 22 from shifting or rotating during the creasing process, ensuring the accuracy of the creasing position and improving the processing quality; the sponge pad 23 can contact and press the cardboard before the creasing knife 221 presses down, preventing the cardboard from moving during the creasing process.

[0042] Example 2

[0043] The difference from Embodiment 1 is that this embodiment discloses how the conveying assembly 1 specifically conveys the cardboard:

[0044] The conveying assembly 1 includes a support frame 11, a conveyor belt 111 is rotatably connected to the inner wall of the support frame 11, a motor 112 is fixedly connected to the front of the support frame 11, and the output end of the motor 112 is fixedly connected to the drive shaft in the conveyor belt 111.

[0045] The automatic and stable conveyor belt 111 driven by motor 112 realizes the automatic and stable conveying of cardboard. The structure is simple and the control is convenient, which provides a foundation for continuous production.

[0046] Limiting plates 12 are provided on both the front and back of the top of the conveyor belt 111.

[0047] Support blocks 121 are fixedly connected to the top front and back of the support frame 11. A slide rod 122 is slidably connected inside the support block 121. The side of the slide rod 122 near the limiting plate 12 is fixedly connected to the outer surface of the limiting plate 12. A threaded knob 123 is threadedly connected to the top of the support block 121. The bottom of the threaded knob 123 contacts the outer surface of the slide rod 122.

[0048] like Figure 4 As shown, by setting the limiting plate 12, specifically by loosening the threaded knob 123 on the top of the support block 121, and then sliding the slide rod 122 to move the limiting plate 12 to a suitable position, and then tightening the threaded knob 123 to press the bottom of the slide rod 122 to fix the limiting plate 12, thereby adapting to cardboard of different widths, ensuring that the cardboard can be accurately conveyed to the creasing station, and improving the accuracy of the creasing position.

[0049] A specific application of this embodiment is as follows: First, adjust the two limiting plates 12 according to the size of the cardboard to be creasing. Loosen the threaded knob 123 on the top of the support block 121. Then, slide the slide rod 122 to move the limiting plate 12 to a suitable position. Next, tighten the threaded knob 123 so that its bottom presses against the slide rod 122 to fix the limiting plate 12. Then, install the creasing knife 221 according to the required creasing line pattern. Align the pin 222 with the insertion hole 223 and insert it. At the same time, ensure that the angle positioning block 224 can be accurately embedded in the angle positioning groove 225. At this time, the magnetic snap 226 on the top of the pin 222 and the magnetic snap 226 on the inner wall of the insertion hole 223 attract each other, thereby holding the creasing knife 221 in place. 1. After installation on the pressure plate 22 and completion of preparation, start the motor 112 to drive the conveyor belt 111 to run. Place the cardboard on the conveyor belt 111 and position it between the two limiting plates 12. The cardboard is conveyed by the conveyor belt 111 to the bottom of the creasing assembly 2. At this time, the electric push rod 211 extends downward and pushes the pressure plate 22 and the creasing knife 221 installed at its bottom downward. During this process, the limiting rod 212 fixed to the top of the pressure plate 22 also moves downward and keeps the pressure plate 22 stable under the guidance of the support frame 21. When the pressure plate 22 moves downward, the sponge pad 23 fixed at its bottom by adhesive first contacts and presses the cardboard. Then the creasing knife 221 creasing the cardboard precisely.
