Description

Technical Field

[0001] This utility model relates to the field of cardboard box folding technology, and in particular to a cardboard box folding device for cardboard box processing. Background Technology

[0002] Cardboard boxes are a common packaging material, mainly made of paper or cardboard, and are widely used in the packaging and transportation of goods. There are many types of cardboard boxes, such as corrugated cardboard boxes and single-layer cardboard boxes. Different cardboard boxes have different uses and characteristics. Cardboard boxes need to be folded during the processing, so it is necessary to design an efficient cardboard box folding device for cardboard box processing.

[0003] For example, a high-efficiency cardboard box folding device for cardboard box processing, disclosed in CN222495615U, uses a rotating folding mechanism. When folding is required, the cardboard box is placed on top of a rotating disk, and a second motor is turned on. The second motor drives a second worm gear to rotate, which in turn drives a rotating plate to rotate via a rotating rod, enabling the rotating plate to fold the cardboard box. When the cardboard box needs to be rotated, a first motor is turned on, which drives a first worm gear to rotate, which in turn drives a rotating disk to rotate via a linkage rod, enabling the rotating disk to rotate the cardboard box and allowing the rotating plate to fold the cardboard box at different positions.

[0004] This high-efficiency cardboard box folding device can fold cardboard boxes using a folding plate. However, since the four sides of a rectangular cardboard box have different lengths and widths, the folding device cannot adjust the position of the box surface on the folding plate according to the creases of the box surface during the folding process. Manual intervention is required, but the accuracy of manual adjustment by eye is poor, and there are cases where the folding position of the cardboard box is deviated.

[0005] Therefore, it is necessary to provide a carton folding device for carton processing to solve the above-mentioned technical problems. Utility Model Content

Figure 3 for Figure 1 The enlarged schematic diagram at point A is shown. A cardboard box folding device for cardboard box processing includes: a base 1;

[0027] A shelf 2 is rotatably mounted on the top center of the base 1. An extension plate 3 is provided on one side of the outer surface of the base 1. A connecting plate 4 is fixedly mounted on the top of the extension plate 3. A fixing plate 5 is fixedly connected to one side of the top of the connecting plate 4. A first hydraulic cylinder 6 is fixedly mounted in the middle of the top of the fixing plate 5. A pressing device 7 is provided at the bottom end of the output shaft of the first hydraulic cylinder 6. The pressing device 7 includes a mounting plate 71, a slide 72, a servo motor 73, a threaded column 74, a moving block 75, a limiting pressure plate 76, a pointing block 77, and a moving groove 78.

[0028] An adjustment device 8 is disposed on one side of the surface of the extrusion device 7. The adjustment device 8 includes a fixing block 81, a scale rod 82, a threaded rod 83, an adjustment block 84, and a stop block 85.

[0029] A folding device 9 is provided on one side of the top of the base 1.

[0030] The mounting plate 71 is disposed at the bottom end of the output shaft of the first hydraulic cylinder 6. The slide groove 72 is opened in the middle of the bottom of the mounting plate 71. The servo motor 73 is fixedly installed in the middle of the rear side of the mounting plate 71. The threaded column 74 is rotatably installed inside the slide groove 72. One end of the threaded column 74 is fixedly connected to the output shaft of the servo motor 73. The moving block 75 is threadedly engaged with the outer surface of the threaded column 74. The limiting pressure plate 76 is fixedly installed at the bottom of the moving block 75. The pointing block 77 is fixedly installed on one side of the top of the limiting pressure plate 76. The moving groove 78 is opened on the other side of the bottom of the mounting plate 71.

[0031] Two fixing blocks 81 are respectively fixedly installed on both sides of the top of the mounting plate 71, the scale rod 82 is fixedly installed between the two fixing blocks 81, the threaded rod 83 is rotatably installed on one side between the two fixing blocks 81, the adjusting block 84 is fixedly installed on one end of the threaded rod 83, and the stop block 85 is threadedly engaged with the outer surface of the threaded rod 83.

[0032] The pointing block 77 is slidably mounted on the outer surface of the scale rod 82, and the stop block 85 is slidably mounted on the other side of the outer surface of the scale rod 82.

[0033] A rotating motor is provided at the bottom of the shelf 2. The motor body is fixedly installed in the middle of the bottom of the base 1 and is used to control the rotation angle of the shelf 2.

[0034] Both the movable block 75 and the stop block 85 have threaded holes on their surfaces. The movable block 75 is threadedly engaged with the outer surface of the threaded post 74 through the threaded hole, and the stop block 85 is threadedly engaged with the outer surface of the threaded rod 83 through the threaded hole.

[0035] The working principle of the cardboard folding device for cardboard box processing provided by this utility model is as follows:

[0036] During operation, firstly, rotating the adjusting block 84 drives the threaded rod 83 to rotate. The threaded rod 83 rotates and engages the threaded stop 85. The stop 85 slides on the surface of the scale rod 82. According to the required length of movement of the carton, the distance between the pointing block 77 and the stop 85 is adjusted to match the fold of the carton to the folding position of the folding device 9. This prevents the limiting pressure plate 76 from moving too far, which could cause the fold of the carton and the folding position of the folding device 9 to misalign, thus improving the accuracy of the carton folding.

[0037] The output shaft of the first hydraulic cylinder 6 moves downward to push the limiting pressure plate 76 to press down on the carton surface. The output shaft of the servo motor 73 moves to push the moving block 75 to slide inside the slide groove 72. The moving block 75 drives the limiting pressure plate 76 to slide, pushing the carton surface on the surface of the shelf plate 2. The crease of the carton surface rests on the folding position of the folding plate of the folding device 9.

[0038] After one side of the carton is folded, the limiting pressure plate 76 moves upward to release the carton. The carton rotates by the rotation of the shelf plate 2, so that the other side of the carton faces the side of the folding device. Then the limiting pressure plate 76 continues to press the carton downward, and the limiting plate 76 is repeatedly controlled to press the carton and slide, so that the crease of the carton moves to the folding position of the folding device 9 to wait for folding.

[0039] Compared with related technologies, the cardboard folding device for cardboard box processing provided by this utility model has the following beneficial effects:

[0040] This utility model provides a carton folding device for carton processing. The output shaft of the servo motor 73 rotates, driving the threaded column 74 to rotate. The rotation of the threaded column 74 engages the threaded moving block 75, which in turn drives the limiting pressure plate 76 to push the carton surface pressed against the surface of the shelf 2. This pushes the folds of the carton surface to the folding position on the surface of the folding device 9 for folding. This facilitates the adjustment of the folding positions of the four sides of the carton with the folding device 9. At the same time, the position of the stop block 85 is adjusted according to the scale rod 82 to prevent the limiting pressure plate 76 from moving too far. This improves the accuracy of the alignment of the folds of the carton surface with the folding position of the folding device 9, avoids folding errors, and enhances the practicality and flexibility of the device.

[0044] The push plate 12 is fixedly connected to the bottom of the connecting plate 4.

[0045] The working principle of the cardboard folding device for cardboard box processing provided by this utility model is as follows:

[0046] During operation, the output shaft of the second hydraulic cylinder 11 moves to push the push plate 12, which in turn moves the connecting plate 4 and the extension plate 3. The extension plate 3 slides inside the storage slot 10, allowing it to move away from or near the base 1. This adjusts the length between the connecting plate 4 and the base 1, making it easier to place cartons of different lengths on the surface of the base 1.
