[0002] With the continuous development and progress of the Internet era, the number of people shopping online is gradually increasing. Therefore, in order to protect the goods and deliver them intact, it is necessary to pack the goods in cartons, which can protect the goods and facilitate the transportation of goods. At the same time, it is also convenient for factories to store processed products. Therefore, cartons occupy an important position in packaging. Some cartons are produced by bending cardboard.

[0003] The cardboard is extruded and formed into a carton by a folding device, and an indentation is formed. The existing production device directly folds the cardboard mechanically, but the cardboard itself has a certain hardness and toughness. Direct extrusion may damage the cardboard and increase production costs.

[0004] Therefore, it is necessary to propose a non-destructive creasing device for carton production to solve the above problems. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a carton non-destructive indentation device for carton production, comprising a support frame, the top end of the support frame is connected to a fixed frame, the interior of the fixed frame is rotatably connected to a plurality of conveying rollers, the bottom end of the fixed frame is connected to two fixed plates, cylinders are fixed to the sides of the two fixed plates away from each other, the top ends of the two cylinders are fixed to connecting plates, the top ends of the two connecting plates are fixed to upper push plates, the top ends of the two upper push plates are arranged as semicircular ends, the semicircular ends are provided with exhaust slots along the length direction, the interior of the exhaust slots is provided with heating wires, a fan is fixed between the two fixed plates, and the fan is connected to the interior of the exhaust slots.

[0007] Preferably, the fan is fixed to the bottom end of the fixing frame, a U-shaped frame is fixed to the middle of the top end of the fixing frame, the U-shaped opening of the U-shaped frame is downward, two sliding rods are fixed to the top end of the U-shaped frame, and a lifting frame is slidably matched on the two sliding rods.

[0008] Preferably, the lifting frame is configured to be U-shaped, and the two bottom ends of the U-shape are connected to lower pressure plates, and the two lower pressure plates are respectively close to the two upper push plates. Two electric push rods are fixed to the bottom end of the lifting frame, and the bottom ends of the two electric push rods are fixed on the U-shaped frame. The length of the U-shaped frame is shorter than the length of the lifting frame.

[0009] Preferably, a plurality of conveying rollers are provided with cardboard for transmission, and two upper push plates extend out of the gaps between the conveying rollers.

[0010] Preferably, the bottom ends of the two lower pressing plates are both configured as semicircles, the arc surfaces of the semicircles face downward, and the two lower pressing plates are pressed against the upper surface of the paperboard.

[0011] Preferably, the two upper push plates are pressed against the lower surface of the paperboard, and a spacing is left between the two lower pressing plates and the corresponding upper push plates.

[0012] Preferably, anti-slip pads are provided at the four corners of the bottom end of the support frame.

[0013] The technical effect of the utility model is that when the cardboard moves to the bottom of the U-shaped frame, the two cylinders extend upward, driving the corresponding upper push plate to extend from between the two conveying rollers, pushing up the lower surface of the cardboard to bend the cardboard, and at the same time, the heating wire and the fan in the upper push plate are started. When the upper push plate rises, the wind force generated by the fan is discharged from the exhaust slot, and the heat of the heating wire can soften the bent area of ​​the cardboard, making the bending of the cardboard smoother.

[0014] When the two upper push plates rise to squeeze the cardboard, the two lower pressure plates are driven by the electric push rod to press down the upper surface of the cardboard at the same time. The lower pressure plates and upper push plates are distributed on both sides of the crease, which can make the bending more neat and ensure smooth bending. At the same time, squeezing up and down at the same time can increase the stability of the cardboard and avoid the cardboard from moving during bending, resulting in deviation of the bending angle.
