[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a folding device for carton production, including a folding device body 1, a roller conveyor 101 at the bottom end of the folding device body 1, a base plate 102 at the middle position of the roller conveyor 101, vertical columns 103 installed on both outer walls of the roller conveyor 101, a crossbeam 104 installed between the two vertical columns 103, a pressure plate 2 connected to the bottom outer wall of the crossbeam 104, folding guide plates 3 installed on both outer walls of the crossbeam 104, the pressure plate 2 and the folding guide plates 3 linked together, a pre-pressure roller 105 slidably connected to the outer wall of the vertical columns 103 facing the roller conveyor 101, the pre-pressure roller 105 rolls along the crease line of the cardboard before formal folding, the pressure is adjusted in real time by the pressure sensor inside the pre-pressure roller 105 to ensure that the crease depth of cardboard of different thicknesses is consistent. Example

[0021] like Figure 1-4 As shown, the base plate 102 is fixedly connected to the inner walls of both sides of the roller conveyor 101. A turntable 106 is rotatably connected to the middle of the base plate 102. The turntable 106 is designed to allow the cardboard to be rotated and its direction adjusted, which is convenient for multi-directional folding of complex box types. The turntable 106 of the base plate 102 is linked with the pre-compression roller 105. The pre-compression roller 105 performs initial pre-compression on the cardboard, and the turntable 106 adjusts the pre-compression position of the cardboard. A groove 107 is provided on the outer wall of the vertical column 103 facing the roller conveyor 101. A support rod 108 is slidably connected in the groove 107. A telescopic rod 109 is rotatably hinged to the end of the support rod 108. A pre-pressing wheel 105 is rotatably connected to the end of the telescopic rod 109. When the device is not in use, the telescopic rod 109 is parallel to the vertical column 103. The telescopic rod 109 drives the pre-pressing wheel 105 to pre-press the creases of the cardboard through its telescopic function. The top of the pressure plate 2 is rotatably connected to the rotating shaft 201, which is mounted on the electric push rod 202. The electric push rod 202 is mounted inside the bottom wall of the crossbeam 104. After the cardboard is pre-pressed, the pressure plate 2 presses down to form the initial folding position of the cardboard. Bases 301 are installed on both outer walls of the crossbeam 104. Ball joints 302 are installed on both bases 301. An "L"-shaped telescopic rod 303 is connected to the top of the ball joint 302. A folding guide plate 3 is installed at the end of the "L"-shaped telescopic rod 303. The folding guide plate 3 is in the shape of an inverted "L". The folding guide plate 3 works with the pressure plate 2 to fold the cardboard completely. At the same time, the ball joints 302 and the "L"-shaped telescopic rod 303 can flexibly adjust the folding angle to ensure that the corners of the carton are folded in place, thereby improving the flatness and load-bearing capacity of the carton. A pressure sensor is installed inside the pre-pressing roller 105. The pressure is adjusted in real time through the pressure sensor to ensure that the crease depth of cardboard of different thicknesses is consistent, which solves the problem of easy breakage or uneven crease depth of traditional rigid crease. The pre-pressing roller 105 is connected to the base plate 102 for signal transmission, and the pressure plate 2 and the folding guide plate 3 are electrically connected. like Figure 5-6 As shown, the cardboard box in this embodiment includes a box body 4. The box body 4 unfolds into a rectangular shape. The bottom shape of the box body 4 matches the shape of the pressure plate 2. The pressure plate 2 matches the bottom shape of the box body 4, making the bottom structure of the folded cardboard box more stable and reducing the risk of deformation.

[0022] The working process of this utility model is as follows: When using a cardboard box and its production folding device, the cardboard to be folded (box body 4 in unfolded state) is first fed into the folding station by the roller conveyor 101 and laid flat on the base plate 102. Then, the pre-pressing roller 105 slides along the slide groove 107 of the vertical column 103 to the edge of the cardboard. The telescopic rod 109 pushes the pre-pressing roller 105 to contact the crease line of the cardboard. The pressure sensor inside the pre-pressing roller 105 monitors the pressure in real time and dynamically adjusts the downward pressure to ensure that the crease depth of cardboard of different thicknesses is consistent. If the cardboard needs to be folded in multiple directions, the turntable 106 rotates to adjust the angle of the cardboard, and the pre-pressing roller 105 pre-presses other crease lines in sequence. After pre-pressing is completed, the electric push rod 202 drives the rotating shaft 201, causing the pressure plate 2 to press down vertically, so that the middle of the cardboard forms a preliminary fold along the pre-press crease. When the pressure plate 2 presses down, the turntable 106 finely adjusts the position of the cardboard to ensure that the pressure plate 2 is completely aligned with the shape of the bottom of the carton, avoiding misalignment and deformation. At the same time, the "L"-shaped telescopic rods 303 on both sides of the crossbeam 104, under the adjustment of the ball joint 302, drive the inverted "L"-shaped folding guide plate 3 to move to the side of the cardboard, and the folding guide plate 3 pushes inward along the pre-press crease line. After folding, the pressure plate 2 and folding guide plate 3 are reset, the roller conveyor 101 sends out the formed carton, and the pre-pressing roller 105 is retracted to the initial position of the vertical column 103 via the telescopic rod 109, ready for the next cycle.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
