[0002] Food packaging boxes are essential containers used to protect and store food, ensuring its safety, freshness, and quality. They are typically made from materials such as cardboard, plastic, metal, or glass, and possess excellent moisture-proof, anti-oxidant, and antibacterial properties to extend the shelf life of food. Cardboard food packaging boxes, for example, require wrapping paper for aesthetics and promotional purposes. Consequently, specialized food packaging box forming machines have emerged.

[0003] Existing food packaging box forming machines have the following problems: 1. It is difficult to change the mold according to the size of the packaging box to be produced, resulting in poor adaptability of the device. A damaged mold may even render the entire device unusable. It is also inconvenient to apply stickers to packaging boxes of different sizes, resulting in the wrapping paper being easily stuck loose. 2. The device lacks a limiting function, making it difficult to push the packaging boxes out neatly after they are formed, resulting in messy stacking of the packaging boxes and causing inconvenience in other subsequent operations. Therefore, a food packaging box forming machine is urgently needed to solve the above problems. Utility Model Content

The third cylinder 7, the connecting frame 8, the moving rod 17 and the roller 18 are each provided with two groups, and the two groups of the third cylinder 7, the connecting frame 8, the moving rod 17 and the roller 18 are symmetrically distributed on both sides of the mold 6, and the top surface of the connecting frame 8 is flush with the top surface of a group of molds 6 near the fourth cylinder 11;

[0024] In this embodiment, when the device is used, first connect the mains power to power the entire device, and use the external control system to control the overall operation of the device. The specific control system model and control method are existing mature technologies and will not be elaborated on here. Then, a mold 6 of corresponding size is selected according to the size of the packaging box. The specific size of the mold 6 can be customized according to the needs. It should be noted that one of the molds 6 connected to the second cylinder 5 has a length, width and height that are consistent with the length, width and height of the inner wall of the packaging box, and another group of molds 6 connected to the fourth cylinder 11 has a length and width that are consistent with the length and width of the outer wall of the packaging box. Then, one side of the mold 6 is tightly fixed to one side of the fixing plate 15. After that, insert the bolt 13 along the inside of the card slot 12, and then thread the nut 14 onto the outer surface of the bolt 13 until one side of the nut 14 is tightly attached to the other side of the fixing plate 15. After assembling the two sets of molds 6 in this way, stick them to the bottom surface of the inner box and one side of the wrapping paper, and then place the two on top of the other set of molds 6. Align the four side edges of the bottom surface of the packaging box with the four side edges of the other set of molds 6, and then start the second cylinder 5 so that the piston end of the second cylinder 5 drives one set of fixing plates 15 and one set of molds 6 to move downward. After the two sets of molds 6 form a clamping state on the bottom surface of the packaging box, pause the second cylinder 5, and then simultaneously Start the two sets of third cylinders 7, and the piston ends of the two sets of third cylinders 7 push the two sets of connecting frames 8 to move. The connecting frames 8 drive the moving rod 17 and the roller 18 to move until the roller 18 is blocked by the other set of molds 6 and cannot move. The roller 18 will reverse and make the moving rod 17 slide along the inside of the connecting frame 8 and squeeze the spring 16. When the spring 16 is significantly compressed, the third cylinder 7 can be paused. Under the rebound force of the spring 16, the spring 16 pushes the moving rod 17, so that the roller 18 is close to the side of the other set of molds 6. At this time, the second cylinder 5 and the fourth cylinder 11 can be started synchronously, so that the piston end of the second cylinder 5 pushes one of the sets of The mold 6 continues to move downward, and the piston end of the fourth cylinder 11 drives the other group of molds 6 to move downward as well, so that the packaging box moves downward as a whole. Under the rolling and pressing of the roller 18, the packaging paper is tightly adhered to both sides of the inner box of the packaging box. Then, the piston ends of the two groups of third cylinders 7 are controlled to retract, so that the two groups of rollers 18 are away from the packaging box. Then, the piston end of the second cylinder 5 is controlled to move upward, so that one group of molds 6 is away from the packaging box. Then, the motor 10 is started so that the output end of the motor 10 drives the bearing and the fourth cylinder 11 to rotate ninety degrees. The other group of molds 6 drives the packaging box to rotate ninety degrees synchronously. Then, the above steps are repeated to perform sticker forming operations on the other two sides of the packaging box.
