Description

Technical Field

[0001] This utility model relates to the field of packaging box processing technology, and more specifically to a packaging box bending device. Background Technology

[0002] As the core carrier for the transportation and storage of goods, the demand for packaging boxes is increasing year by year. In the packaging box forming process, the bending process is one of the key links. Its function is to bend the sheet material to form the box structure, which directly affects the strength, sealing performance and production efficiency of the packaging box.

[0003] A search revealed Chinese patent CN213103901U, which discloses a box-type bending machine. This device adds a movable stage at the front of the worktable to increase the contact area of ​​the workpiece, facilitating the bending of larger box-type workpieces, ensuring smooth bending, and improving bending efficiency. Simultaneously, the electric motor is started while the first hydraulic cylinder is working. The electric motor causes the assist rod to lift the excess workpiece along the trajectory, preventing the workpiece from bending due to its own weight. This device can only bend the sheet metal once at a time. If a large number of sheets need to be bent, the time consumed is long and the efficiency is low. Utility Model Content

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Reference Figures 1-4 This utility model provides a packaging box bending device, including a workbench 1. A U-shaped frame 2 is bolted to the upper surface of the workbench 1. A cylinder 5 is bolted to the inner top wall of the U-shaped frame 2. The output end of the cylinder 5 passes through the inner top wall of the U-shaped frame 2 and is bolted to a slide 4. Two symmetrical connecting plates 6 are bolted to the bottom of the slide 4. Both ends of the connecting plates 6 are provided with multiple equally spaced mounting holes 7. One mounting hole 7 contains a screw 9. The bottom ends of the two connecting plates 6 are threadedly connected to L-shaped bending plates 8 by screws 9. A bottom mold 3 is bolted to the upper surface of the workbench 1. Multiple sliding grooves 10 are opened at both ends of the upper surface of the bottom mold 3. Side plates 11 are slidably connected in the two sets of sliding grooves 10. Two sets of symmetrical mounting holes 12 are opened on both sides of the bottom mold 3. Both sides of plate 11 are equipped with screws 13 that mate with mounting holes 12. When the bending width needs to be adjusted, first adjust the distance between the two L-shaped bending plates 8. During adjustment, first remove multiple screws 9 and move the distance between the L-shaped bending plates 8. After the movement is completed, fix the L-shaped bending plates 8 by passing the screws 9 through the corresponding mounting holes 7. Then adjust the width of the bottom mold 3. During adjustment, remove multiple screws 13 on both sides of the side plate 11 and then move the two side plates 11 along the slide groove 10. When they are in the same position as the L-shaped bending plates 8, reinstall the screws 13 and fix the side plates 11 to the bottom mold 3. The bending width can then be adjusted. By adjusting the distance between the two L-shaped bending plates 8 and the width of the bottom mold 3, the bending width of the packaging box plate can be adjusted. The structure is simple and convenient to use.

[0022] In this invention, a bidirectional lead screw 14 is rotatably connected between the inner walls of the two sides of the U-shaped frame 2 via bearings. Two symmetrical slides 15 are threaded onto the bidirectional lead screw 14. Two symmetrical stop bars 16 that block the ends of the sheet material are rotatably connected to the upper surface of the slides 15. The two ends of the bidirectional lead screw 14 pass through the outer walls of the two sides of the U-shaped frame 2 and are threaded onto rotating disks. When it is necessary to limit the ends of the packaging box sheet material, first rotate the bidirectional lead screw 14 to make the two sets of stop bars 16 on the slides 15 move away from each other. Then, place the packaging box sheet material to be bent on the bottom mold 3. Then, rotate the bidirectional lead screw 14 in the opposite direction until the two sets of stop bars 16 contact the two sides of the packaging box sheet material. With the provided slides 15 and the stop bars 16 on them, the ends of the sheet material to be bent can be limited when it is placed, which makes it convenient for the staff to place the sheet material in the middle position on the bottom mold 3. Multiple limits can be set for the same type of sheet material with one adjustment, which can save time.

[0023] In this invention, the upper surface of the bottom mold 3 is provided with two symmetrical clearance grooves 17. One side of the bottom mold 3 is fixedly connected to two symmetrical fixing blocks 18 by bolts. The two fixing blocks 18 are rotatably connected to a rotating rod 19 by bearings. Two strip plates 20 that cooperate with the clearance grooves 17 are welded to the outer circumference of the rotating rod 19. One end of the two strip plates 20 is fixedly connected to a handle 21 by bolts. A rubber ring is adhered to the outer circumference of the handle 21. The surface of the rubber ring is provided with anti-slip texture. After bending, the handle 21 is lifted upwards, so that the strip plate 20 rotates along the rotating rod 19 at one end. During the process of lifting the strip plate 20, the bent plate is lifted up and slides to the outside of the device. With the provided strip plates 20, the bent plate can be lifted off the surface of the bottom mold 3 after processing, which is convenient for material removal.

[0024] The use of this utility model involves the following steps:

[0025] S1: When it is necessary to limit the two ends of the packaging box material, first rotate the double-acting screw 14 to make the two sets of stop bars 16 on the slide block 15 move away from each other. Then place the packaging box material to be bent on the bottom mold 3, and then rotate the double-acting screw 14 in the opposite direction until the two sets of stop bars 16 contact the two sides of the packaging box material respectively.

[0026] S2: When it is necessary to adjust the width of the bend, first adjust the distance between the two L-shaped bending plates 8. When adjusting, first remove multiple screws 9, move the distance between the L-shaped bending plates 8, and after the movement is completed, fix the L-shaped bending plates 8 by passing the screws 9 through the corresponding mounting holes 7.

[0027] S3: Then adjust the width of the bottom mold 3. During the adjustment, remove the screws 13 on both sides of the side plate 11. Then move the two side plates 11 to slide along the slide groove 10. When they are in line with the position of the L-shaped bending plate 8, reinstall the screws 13 and fix the side plate 11 to the bottom mold 3. The bending width adjustment can then be completed.

[0028] S4: After bending is completed, lift the handle 21 upwards to make the strip plate 20 rotate along the rotating rod 19 at one end. During the process of lifting the strip plate 20, the bent plate is lifted up and slides to the outside of the device.
