[0021] In the embodiment of the present application, by providing a carton bending device for carton production, the problem that the carton board is prone to shift during multiple bending processes of the carton board, resulting in an inclined indentation of the carton board and affecting the subsequent bending and forming of the carton, is effectively solved. The carton bending device for carton production moves two sliding rods closer to each other, reducing the gap between the two sliding rods, adjusting the gap adapted to the width of the cardboard, playing a limiting role on the cardboard, placing the cardboard under the connecting arm, starting the hydraulic cylinder, causing the telescopic rod to move downward, driving the bending plate to move downward through the downward movement of the telescopic rod, applying a force to the cardboard through the downward movement of the bending plate to complete the bending process of the cardboard. When it is necessary to bend other parts of the cardboard, the staff pulls one end of the cardboard to move it, and then starts the hydraulic cylinder to make the bending plate move downward to continue the bending process of other parts of the cardboard. The device limits the cardboard through two sliding rods, avoiding the problem that the position of the cardboard shifts, resulting in an inclined indentation of the carton board and affecting the subsequent bending and forming of the carton. By evenly and equidistantly rotating rollers installed in each sliding rod, the friction between the cardboard and the sliding rod during movement is reduced. A connecting plate is fixedly installed on the connecting block, a pressing plate is arranged below the connecting plate, and the pressing plate is fixedly connected to the connecting plate through two springs, so that when bending the cardboard, the pressing plate can fix one end of the cardboard to prevent it from moving during processing.
[0022] Embodiment: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that during the multiple bending processes of the carton board, the carton board is easily offset, resulting in the indentation of the carton board being tilted, which affects the subsequent bending and forming of the carton. The overall idea is as follows:

A slider 22 is fixedly installed in the middle of the bottom end of each slide bar 2. Threaded holes are provided on the surfaces of the two sliders 22, and the thread directions of the two threaded holes are opposite. Slide grooves 11 are provided on both sides of the upper surface of the placement plate 1. The two sliders 22 are respectively slidably installed in the slide grooves 11. A threaded rod 6 is rotatably installed in the placement plate 1. The threaded rod 6 passes through the two threaded holes. A hand wheel 61 is fixedly connected to the end of the threaded rod 6. The hand wheel 61 is located on one side of the placement plate 1. The connecting block Guide rods 43 are fixedly installed on both sides of the upper end of 41, and the two guide rods 43 are movable through the connecting arm 3. The cardboard is placed in the placement plate 1 and placed between the two slide bars 2. The threaded rod 6 is rotated by twisting the hand wheel 61. The rotation of the threaded rod 6 drives the two slide bars 2 to move closer to or away from each other. The two slide bars 2 move closer to each other, narrow the gap between the two slide bars 2, adjust the gap to match the width of the cardboard, and limit the cardboard. The cardboard is placed under the connecting arm 3, and the hydraulic cylinder 4 is started to extend. The retracting rod moves downward, and the bending plate 42 is driven downward by the telescopic rod. The bending plate 42 exerts a force on the paperboard through the downward movement of the bending plate 42 to complete the bending process of the paperboard. When it is necessary to bend other parts of the paperboard, the staff pulls one end of the paperboard to move it, and then starts the hydraulic cylinder 4 to move the bending plate 42 downward to continue bending other parts of the paperboard. The device limits the paperboard through two sliding rods 2 to avoid the position deviation of the paperboard, which causes the indentation of the carton board to be tilted, affecting the subsequent bending and forming of the carton;
[0024] A connecting plate 5 is fixedly installed at the end of the connecting block 41, and a pressing plate 51 is arranged below the connecting plate 5. Round rods 52 are fixedly installed on both sides of the upper end of the pressing plate 51. The two round rods 52 are movably inserted through the connecting plate 5. A spring 53 is movably sleeved on each round rod 52. The pressing plate 51 is fixedly connected to the connecting plate 5 through two springs 53. Rollers 21 are equidistantly installed in each slide bar 2 to reduce the friction between the cardboard and the slide bar 2 when the cardboard moves. The connecting plate 5 is fixedly installed on the connecting block 41, and a pressing plate 51 is arranged below the connecting plate 5. The pressing plate 51 is fixedly connected to the connecting plate 5 through two springs 53, so that when the cardboard is bent, the pressing plate 51 can fix one end of the cardboard to prevent it from moving during processing.
[0025] Working principle:
[0026] The first step is to place the cardboard on the placement plate 1 and between the two slide bars 2, and rotate the threaded rod 6 by twisting the hand wheel 61. The rotation of the threaded rod 6 drives the two slide bars 2 to move closer to or away from each other. The two slide bars 2 move closer to each other, narrow the gap between the two slide bars 2, adjust the gap to match the width of the cardboard, and limit the cardboard. The cardboard is located under the connecting arm 3, and the hydraulic cylinder 4 is started to move the telescopic rod downward. The bending plate 42 is driven downward by the telescopic rod. The cardboard is applied with force by the downward movement of the bending plate 42 to complete the bending process of the cardboard. When it is necessary to bend other parts of the cardboard, the staff pulls one end of the cardboard to move it, and then starts the hydraulic cylinder 4 to move the bending plate 42 downward to continue bending other parts of the cardboard. The device limits the cardboard through the two slide bars 2 to avoid the position shift of the cardboard, which causes the indentation of the carton board to be tilted, affecting the subsequent bending and forming of the carton.
[0027] In the second step, rollers 21 are evenly and rotatably installed in each slide bar 2 to reduce the friction between the cardboard and the slide bar 2 when the cardboard moves. A connecting plate 5 is fixedly installed on the connecting block 41, and a pressing plate 51 is arranged under the connecting plate 5. The pressing plate 51 is fixedly connected to the connecting plate 5 by two springs 53, so that when the cardboard is bent, the pressing plate 51 can fix one end of the cardboard to prevent it from moving during processing.
