[0032] Please see Figure 1-6 This utility model provides a technical solution: a packaging box indentation and folding calibration device, including a base 1, a fixed bracket 3 installed on the upper end of the base 1, a sliding groove 5 opened on the upper end of the fixed bracket 3, a limiting component, the limiting component is set on the fixed bracket 3, and a folding calibration component, the folding calibration component is set on the base 1, the folding calibration component includes a hydraulic rod 13, the hydraulic rod 13 is fixedly connected to the upper end of the base 1, the output end of the hydraulic rod 13 is fixedly connected to a support frame 14, two second guide rods 15 are fixedly connected to the upper end of the base 1, both second guide rods 15 are slidably connected to the support frame 14, a first push plate 16 is fixedly connected to the upper end of the support frame 14, a connecting bracket 20 is fixedly connected to the upper end of the first push plate 16, an electric push rod 21 is fixedly connected inside the connecting bracket 20, a baffle 22 is fixedly connected to the output end of the electric push rod 21, two fourth guide rods 23 are fixedly connected to the front surface of the baffle 22, both fourth guide rods 23 are slidably connected to the connecting bracket 20.

[0033] The folding calibration assembly also includes two second push plates 17, which are respectively disposed on the left and right sides of the first push plate 16. Two third guide rods 19 are fixedly connected to both the left and right sides of the first push plate 16. The four third guide rods 19 are slidably connected to the corresponding second push plates 17. The left and right sides of the first push plate 16 are rotatably connected to second threaded rods 18, and the two second push plates 17 are threaded onto the surface of the second threaded rods 18.

[0034] There are two sets of edge calibration components, which are symmetrically arranged on the front and rear sides of the upper end of the base 1.

[0035] The limiting assembly includes a guide frame 6, which is slidably connected to the lower inner wall of the slide 5. A slider 7 is slidably connected to the upper inner wall of the slide 5. The guide frame 6 and the slider 7 are fixed by bolts. An electric telescopic rod 8 is slidably connected to the surface of the guide frame 6. The electric telescopic rod 8 is fixed to the guide frame 6 by bolts. A first pressure block 9 is fixedly connected to the output end of the electric telescopic rod 8. A second pressure block 10 is provided on both the left and right sides of the first pressure block 9. A first guide rod 12 is fixedly connected to both the left and right sides of the first pressure block 9. The two first guide rods 12 are slidably connected to the corresponding second pressure blocks 10. A first threaded rod 11 is rotatably connected to both the left and right sides of the first pressure block 9. The two second pressure blocks 10 are threaded onto the surface of the corresponding first threaded rod 11.

[0036] The limiting components are arranged in two sets, symmetrically on the front and rear sides of the fixed bracket 3.

[0037] A conveyor belt 2 is installed on the upper end of the base 1, and support plates 4 are fixedly connected to both the front and rear sides of the conveyor belt 2.

[0038] When using the device, the creasing-treated packaging paper is conveyed from left to right by the conveyor belt 2, and the support plates 4 on the front and rear sides of the conveyor belt provide lateral support for the packaging paper; when the packaging paper is conveyed to the vicinity of the first push plate 16, the device enters the calibration operation stage.

[0039] The electric push rod 21 is activated to extend it, which drives the baffle 22 to move along the direction of the fourth guide rod 23. Through the contact between the baffle 22 and the edge of the packaging box paper, its front and back positions are precisely calibrated to ensure that the crease position of the packaging box paper is aligned with the folding edge assembly.

[0040] After the position calibration is completed, the electric telescopic rod 8 is activated to extend it, which drives the first pressure block 9 and the second pressure block 10 to descend synchronously until they contact the surface of the packaging box paper and apply pressure to achieve the pressing and positioning of the packaging box paper.

[0041] If it is necessary to adapt to packaging paper of different widths, the first threaded rod 11 can be rotated, and the second pressure block 10 can be driven to slide along the first guide rod 12 through the threaded transmission. The distance between the two second pressure blocks 10 can be adjusted to ensure that packaging paper of different widths can be stably limited.

[0042] After the limit is completed, the hydraulic rod 13 is activated to extend it, which drives the support frame 14 to slide upward along the second guide rod 15, thereby pushing the first push plate 16 and the second push plate 17 to rise synchronously. During the rising process, the first push plate 16 acts on the middle crease of the packaging box paper, and the second push plates 17 on the left and right sides act on the side creases. Under the synergistic effect of the three, the packaging box paper curls up along the preset crease.

[0043] If it is necessary to adapt to packaging paper of different lengths, the second threaded rod 18 can be rotated, and the second push plate 17 can be driven to slide along the third guide rod 19 through the threaded transmission. The distance between the two second push plates 17 can be adjusted to match the folding requirements of packaging paper of different widths.

[0044] After the packaging box paper curls up, the electric push rod 21 is activated again to extend it further. The baffle 22 then presses the edge of the curled packaging box paper inward to complete the precise calibration of the folded edge.

[0045] For packaging boxes of different specifications, the sliding position of the guide frame 6 in the slide groove 5 and the fixed position of the electric telescopic rod 8 on the surface of the guide frame 6 can be adjusted, and the spacing between the second pressure block 10 and the second push plate 17 can be adjusted to adapt the folding operation of packaging boxes of different widths without the need for frequent replacement of equipment parts.

[0046] After a single edge calibration is completed, the electric telescopic rod 8 retracts, causing the first pressure block 9 and the second pressure block 10 to rise and reset. The hydraulic rod 13 retracts, causing the first push plate 16 and the second push plate 17 to fall and reset. The electric push rod 21 retracts, causing the baffle 22 to return to its original position. The conveyor belt 2 continues to transport the next packaging box paper, entering the next work cycle.

[0047] Furthermore, the first threaded rod 11 drives the second pressure block 10 to slide along the first guide rod 12, adjusting the distance between the two second pressure blocks 10 to adapt to packaging paper of different widths; the second threaded rod 18 can drive the second push plate 17 to slide along the third guide rod 19, adjusting the distance between the two second push plates 17. The sliding position of the guide frame 6 in the slide groove 5 and the fixed position of the electric telescopic rod 8 on the surface of the guide frame 6 can be adjusted, further expanding the adaptability range of the device to packaging paper of different specifications, eliminating the need for frequent replacement of equipment parts, and effectively improving the practicality of the device.

[0048] The electric push rod 21 drives the baffle 22 to move along the fourth guide rod 23, which can accurately calibrate the front and back positions of the packaging box paper to ensure that the crease is aligned with the folding edge assembly; the electric telescopic rod 8 drives the first pressure block 9 and the second pressure block 10 to descend, which can stably press the packaging box paper and prevent displacement during the folding process; in the folding edge calibration assembly, the first push plate 16 and the second push plate 17 work together to make the packaging box paper curl up along the crease, and then the baffle 22 squeezes to complete the folding edge calibration, reducing folding edge deviation and improving the processing quality of the packaging box.
