[0025] Please see Figures 1-4 This utility model provides a technical solution: a folding and bonding device for food packaging boxes, including a base plate 1, a pressing mold 10 fixedly installed on the upper surface of the base plate 1, a pressing groove 11 provided in the pressing mold 10, the front and rear ends and the top of the pressing groove 11 are all connected to the outside, side folding plates 14 are rotatably connected to the front and rear sides of the pressing mold 10, a servo motor 15 is coaxially provided at the end of the side folding plate 14, a support frame 2 is fixedly installed on the top surface of the base plate 1, a first cylinder 20 is fixedly installed on the top plate of the support frame 2, a pressing protrusion 22 is provided on the telescopic shaft of the first cylinder 20, the pressing protrusion 22 is located directly above the pressing groove 11, so that the cardboard is squeezed into the pressing groove 11 to complete the initial forming operation by moving the pressing groove 11 downward;

[0026] Specifically, two symmetrical second cylinders 23 are fixedly installed on the top plate of the support frame 2. A top plate 24 is provided on the telescopic shaft of the second cylinder 23. Two symmetrical vertical pipes 25 are fixedly installed on the bottom surface of the top plate 24. An extrusion end 251 is fixedly installed at the bottom end of the vertical pipe 25. A metering pump 26 is provided on one side of the top plate 24. The vertical pipe 25 and the metering pump 26 are connected by a delivery pipe 262, so that the metering pump 26 can extrude the glue onto the cardboard on both sides of the packaging box. Then, with the rotation of the side folding plate 14, the side cardboard is folded so that the side cardboard can be glued to the cardboard box that is initially formed in the lower pressure groove 11.

[0027] In this embodiment, a fixing plate 21 is fixedly installed at the end of the telescopic shaft of the first cylinder 20, and the pressing protrusion 22 is fixedly installed on the bottom surface of the fixing plate 21 by multiple fastening screws, which facilitates the fixing and installation operation.

[0028] Specifically, a suction pipe 261 is fixedly installed at the inlet end of the metering pump 26, and the delivery pipe 262 is a soft tube. The end of the suction pipe 261 is connected to an external adhesive storage tank, so as to enable the normal delivery of adhesive.

[0029] Furthermore, two symmetrical support pads 12 are fixedly installed on the upper surface of the base plate 1. The pressing mold 10 is located between the two support pads 12. The top surface of the pressing mold 10 and the top surface of the support pads 12 are on the same horizontal plane. The side of the support pads 12 is fixedly installed on the side of the pressing mold 10, so that the support pads 12 can support the cardboard.

[0030] In addition, multiple support legs 13 arranged in a matrix are fixedly installed on the bottom surface of the base plate 1. The height of the support legs 13 is greater than 5cm, so that stable support operation can be achieved by using the support legs 13.

[0031] It is worth noting that an electric push rod 16 is provided below the base plate 1. The end of the telescopic shaft of the electric push rod 16 passes through the base plate 1 and is fixedly installed with an ejector plate 17. The ejector plate 17 is located in the lower pressure groove 11, ensuring that the folded and glued cardboard box can be ejected outward by the ejector plate 17 during use.

[0032] It is worth noting that the thickness of the ejector plate 17 is less than 1 cm, and the size of the ejector plate 17 is adapted to the size of the lower pressure groove 11 for stable movement of the ejector plate 17.

[0033] In use, the folding and gluing device for the food packaging box of this utility model involves correctly placing the cardboard with creases or preliminary processing on the top surface of the support pad 12 and the pressing mold 10. Then, the first cylinder 20 is activated, and its telescopic shaft extends, driving the pressing protrusion 22 to press the cardboard into the pressing groove 11 to complete the preliminary forming operation. Next, the second cylinder 23 is activated, and its telescopic shaft extends, driving the vertical tube 25 and the extrusion end 251 downwards to the bottom side of the cardboard box. Finally, the metering pump 26 is activated. 26 operates to extrude the adhesive along the extrusion end 251 onto the side panel of the cardboard box. After the adhesive is extruded, the second cylinder 23 operates, and its telescopic shaft shortens, causing the vertical tube 25 and the extrusion end 251 to move upward and return to the initial position. Then, the servo motor 15 is connected to an external power source and operates. The output shaft of the servo motor 15 rotates, causing the side folding plate 14 to rotate, thereby folding the side panel of the cardboard box and bonding it to the side of the cardboard box with adhesive. After preparation is completed, the electric push rod 16 operates, and its telescopic shaft extends, causing the ejector plate 17 to eject the prepared cardboard box outward, completing the unloading.
