[0002] Packaging box folding and unfolding equipment can automatically complete the folding and sealing of cardboard boxes, significantly improving packaging speed, reducing manual operation, and thus improving production efficiency. Modern packaging box folding and unfolding equipment is usually highly flexible and can adapt to cardboard boxes of different sizes and materials to meet diverse packaging needs.

[0003] The existing patent CN 221341338 U discloses a packaging box disassembly and folding device. The packaging box to be disassembled is placed on a conveyor belt, and multiple mechanical grippers disassemble it and place it into a limiting basket. The control panel controls the track control module, thereby controlling the movement frequency of the small sliding track and the large sliding track. The glue in the glue tank is applied to the cardboard box through a telescopic glue injection device. The cardboard box moves to the large sliding track with a sliding rod through the small sliding track. Then, the telescopic pressure plate presses the cardboard box into the large sliding track. The pre-set telescopic plate can accommodate cardboard boxes of various sizes. After disassembly and folding, the cardboard box is clamped out by mechanical grippers.

[0004] When the aforementioned device squeezes the cardboard box using the telescopic pressure plate, the contact area between the telescopic pressure plate and the cardboard box will change due to the different sizes of the cardboard box. This results in the telescopic pressure plate not being able to make good contact when processing cardboard boxes of different sizes. Utility Model Content

[0005] The purpose of this utility model is to provide a packaging box folding and unfolding device to solve the problem that the contact area between the telescopic pressure plate and the paper box will change due to different paper box sizes, resulting in the telescopic pressure plate not being able to make good contact when handling paper boxes of different sizes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a packaging box unpacking and folding device, including a conveyor belt, a sliding frame at the top of the conveyor belt, an electric push rod installed inside the sliding frame, a pressure plate fixed at the output end of the electric push rod, the pressure plate automatically extending to better contact with paper boxes of different sizes, a squeezing column slidably connected to the middle of the pressure plate, a conical column fixed at the top of the squeezing column, when the electric push rod drives the pressure plate to contact the paper box, the squeezing column is squeezed by the paper box, the squeezing column squeezes the conical column to move, four wedge plates are provided on the outer side of the conical column, and a sliding plate is provided on the outer side of the wedge plates, the conical column squeezes multiple wedge plates to move outward, the wedge plates drive the sliding plate to move outward through the sliding column and spring.

The top and bottom of the second telescopic plate 303 are fixed with rotating columns 304. The rotating columns 304 are located inside the second slide groove 302. Pulling the second telescopic plate 303 causes the second telescopic plate 303 to slide and extend through the rotating columns 304.

[0024] In this embodiment: Pulling the second telescopic plate 303 causes it to slide and extend through the rotating column 304. When pulling to the desired position, pushing the second telescopic plate 303 to one side causes it to rotate through the rotating column 304, thereby adjusting the angle of the second telescopic plate 303. Adjusting the angles of the four corners of the second telescopic plate 303 better secures the cardboard box.

[0025] Working principle: When the electric push rod 201 drives the pressure plate 202 to contact the cardboard box, the squeezing column 205 will be squeezed by the cardboard box. The squeezing column 205 squeezes the conical column 207 to move. The conical column 207 squeezes multiple wedge plates 208 to move outward. The wedge plates 208 drive the sliding plate 209 to move outward through the sliding column 210 and the spring 211, so that the pressure plate 202 can automatically extend and make better contact with cardboard boxes of different sizes.

[0026] The cardboard box is pressed into the large sliding track 103 by the pressure plate 202. The pre-set No. 1 telescopic plate 3 and No. 2 telescopic plate 303 can adapt to cardboard boxes of various sizes. Pulling the No. 2 telescopic plate 303 causes it to slide and extend through the rotating column 304. When pulling to the desired position, push the No. 2 telescopic plate 303 to one side, causing it to rotate through the rotating column 304, thereby adjusting the angle of the No. 2 telescopic plate 303. Adjusting the angles of the four corners of the No. 2 telescopic plates 303 better fixes the cardboard box.
