Description

Technical Field

[0001] This utility model relates to the field of folding mechanism technology, specifically a pressure-resistant corrugated cardboard box folding mechanism. Background Technology

[0002] Corrugated cardboard boxes are a common type of packaging container widely used for transporting and storing various goods. They are made of corrugated cardboard, which consists of one or more corrugated (corrugated) core paper layers and flat cardboard sheets (face paper) bonded to the sides of the corrugations. When manufactured, a corrugated cardboard box is a single, straight board. To facilitate folding during later use, fold lines are pressed into the surface of the board, currently achieved through appropriate folding mechanisms.

[0003] Patent CN215751012U discloses a corrugated cardboard box folding mechanism, including a folding platform. Bases are fixedly connected to the four corners of the folding platform's bottom. A folding groove is provided on the outer side of the folding platform. A column is fixedly connected to the outer side of the folding platform, and a crossbar is provided on the outer side of the column. A guide post is fixedly connected to the bottom of the crossbar, and a fixing rod is fixedly connected to the bottom of the guide post. A creasing plate is fixedly connected to the bottom of the fixing rod. The crossbar is slidably connected to the inner side of a first groove, which is located inside the column. This folding mechanism, by providing a folding groove on the outer side of the folding platform and a creasing plate above the folding groove, uses a first motor located inside the column to drive the creasing plate downwards to fold the corrugated paper. The corrugated paper sinks into the folding groove to form a crease, facilitating subsequent folding. This device has a simple structure, greatly improves folding efficiency, and reduces manpower.

[0004] However, the above-mentioned folding mechanism still has the following problems in actual use:

[0005] When folding a corrugated cardboard box, when the middle of the box is pressed into the center by the upper crease plate, the two ends of the box will "curl up" because the box itself has a certain degree of compression resistance and rigidity. However, the four push plates at the four corners of the folding platform are too low, which may prevent the box from being pushed or folded. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this utility model provides a pressure-resistant corrugated cardboard box folding mechanism to solve the problem that when corrugated cardboard boxes are subjected to pressure from the upper indentation plate, both ends curl upwards, making it impossible to push the corrugated cardboard box or fold it.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pressure-resistant corrugated cardboard box folding mechanism, comprising a folding platform, a column installed on one side of the folding platform, an indentation plate installed on the column, and a folding groove formed in the middle of the upper surface of the folding platform. Two clamping plates symmetrically arranged with respect to the folding groove are hinged to the upper surface of the folding platform. Each clamping plate has an adjustment cavity on the side near the folding groove. A sliding opening is formed through the upper surface of each of the two adjustment cavities. A distance adjustment component is connected to the inner wall of each of the two adjustment cavities. Two sliding openings are formed through the upper surface of each of the two distance adjustment components. Support blocks are fixedly connected to both ends of the folding platform near the column. A rotating component and a moving component are connected between the two support blocks. One end of the moving component is connected to the rotating component, and two pulling components are connected to the other two ends of the moving component. The other ends of the two pulling components are respectively connected to the outer walls of the two clamping plates.

[0008] Furthermore, the rotating assembly includes a bidirectional lead screw and a gear. The gear is sleeved and fixedly connected to the middle of the bidirectional lead screw. The two ends of the bidirectional lead screw are rotatably connected to the inner walls of the two support blocks, respectively. The end of the moving assembly away from the pulling assembly is connected to the bidirectional lead screw.

[0009] Furthermore, the moving component includes an auxiliary rod and two moving blocks. The two ends of the auxiliary rod are fixedly connected to the inner walls of the two support blocks, respectively. The auxiliary rod passes through the two moving blocks and is slidably connected to the inner walls of the two moving blocks. The two moving blocks are respectively sleeved and threaded to the two ends of the bidirectional lead screw. The side walls of the two moving blocks are respectively connected to two pulling components.

[0010] Furthermore, the pulling assembly includes a pull block, a pull rope, and a connecting block. One end of the pull block is fixedly connected to the outer wall of the clamping plate, one side of the pull block is fixedly connected to one end of the pull rope, the other end of the pull rope is fixedly connected to one side of the connecting block, and one end of the connecting block is fixedly connected to the side wall of the moving block.

[0011] Furthermore, a rack is fixedly connected to the side of the indentation plate near the column, and the rack meshes with a gear.

[0012] Furthermore, the distance adjustment assembly includes a push plate and a threaded rod. The push plate is located inside the adjustment cavity, and its upper and lower surfaces are slidably connected to the inner wall of the adjustment cavity. The middle part of the upper surface of the push plate is fixedly connected to the lower end of the threaded rod, and the upper end of the threaded rod passes through the sliding opening.

[0013] Furthermore, a threaded ring is fitted and threadedly connected to the outer wall of one end of the threaded rod that passes through the sliding opening, and the bottom surface of the threaded ring abuts against the upper surface of the clamping plate.

[0014] Furthermore, an anti-detachment groove is provided on the side of the adjustment cavity near the sliding opening, and an anti-detachment block is fixedly connected to the upper surface of the push plate. The outer wall of the anti-detachment block is slidably connected to the inner wall of the anti-detachment groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This type of compression-resistant corrugated cardboard box folding mechanism features two hinged clamps on the folding platform, and a rotating component, a moving component, and two pulling components on the side of the folding platform near the column. The two pulling components are connected to the two clamps. When the user creases and folds the corrugated cardboard box through the folding platform, they only need to insert the corrugated cardboard into the two adjusting cavities. Then, as the crease is pressed out under the crease plate, the two clamps automatically lift up both ends of the corrugated cardboard, making it easier to fold and shape the corrugated cardboard.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1-6A pressure-resistant corrugated cardboard box folding mechanism includes a folding platform 1, a column 2 installed on one side of the folding platform 1, an indentation plate 3 installed on the column 2, and a folding groove 101 formed in the middle of the upper surface of the folding platform 1. Two clamping plates 4 are hinged to the upper surface of the folding platform 1 and are symmetrically arranged with respect to the folding groove 101. Each clamping plate 4 has an adjustment cavity 401 on the side near the folding groove 101. Each adjustment cavity 401 has a sliding opening 402 through its upper surface. Each adjustment cavity 401 has a distance adjustment component connected to its inner wall. Each distance adjustment component has a sliding opening 402 through its upper surface. Each end of the folding platform 1 near the column 2 is fixedly connected to a support block 8. A rotating component and a moving component are connected between the two support blocks 8. One end of the moving component is connected to the rotating component, and the other two ends of the moving component are connected to two pulling components. The other ends of the two pulling components are connected to the outer walls of the two clamping plates 4 respectively.

[0026] The compression-resistant corrugated cardboard box folding mechanism in this utility model is structurally similar to existing corrugated cardboard box folding mechanisms, such as the corrugated cardboard box folding mechanism disclosed in patent publication number CN215751012U. Figures 1 to 6 As shown, the anti-compression corrugated cardboard box folding mechanism of this utility model only requires inserting the corrugated cardboard into the two adjustment cavities 401 when creased and folded. Then, the distance between the two ends of the corrugated cardboard is adjusted by the two distance adjustment components (because the crease of the corrugated cardboard is not necessarily in the exact center, but mostly off to one end). When the distance is appropriate, the creased plate 3 is pressed down. While the crease is pressed into the corrugated cardboard, the two ends of the corrugated cardboard located between the two clamps 4 will automatically curl upward. At the same time, the rotating component drives the moving component to move to one side. While the moving component moves, it can pull the two pulling components along with it. At the same time, it pulls the two clamps 4 upward together. Therefore, when the corrugated cardboard curls up, the two clamps 4 will also curl up. At this time, the corrugated cardboard can always maintain a folded angle under the action of the creased plate 3 and the two clamps 4, so it is easier to fold and shape the corrugated cardboard.

[0027] It should be noted that the folding platform 1, column 2 and indentation plate 3 mentioned above are all existing technologies as described in announcement number CN215751012U, so their shape, principle and other details will not be described in detail.

[0028] like Figure 2 and Figure 3 As shown, the rotating assembly includes a bidirectional lead screw 9 and a gear 11. The gear 11 is sleeved and fixedly connected to the middle of the bidirectional lead screw 9. The two ends of the bidirectional lead screw 9 are rotatably connected to the inner walls of the two support blocks 8 respectively. The end of the moving assembly away from the pulling assembly is connected to the bidirectional lead screw 9.

[0029] More specifically, when it is necessary to control the two clamping plates 4 to tilt upwards, simply rotate the gear 11. After the gear 11 rotates, it can drive the bidirectional lead screw 9 to rotate between the two support blocks 8, thereby moving the moving component connected to the surface of the bidirectional lead screw 9.

[0030] like Figures 2-4 As shown, the moving component includes an auxiliary rod 15 and two moving blocks 13. The two ends of the auxiliary rod 15 are fixedly connected to the inner walls of the two support blocks 8 respectively. The auxiliary rod 15 passes through the two moving blocks 13 and is slidably connected to the inner walls of the two moving blocks 13. The two moving blocks 13 are respectively sleeved and threaded to the two ends of the bidirectional lead screw 9. The side walls of the two moving blocks 13 are respectively connected to the two pulling components.

[0031] More specifically, when the bidirectional lead screw 9 rotates, the two moving blocks 13 threaded to its surface can only move toward the middle at the same time under the limitation of the auxiliary rod 15. While the two moving blocks 13 are moving, they can pull the two pulling components upward.

[0032] like Figures 3-5 As shown, the pulling assembly includes a pull block 10, a pull rope 14, and a connecting block 16. One end of the pull block 10 is fixedly connected to the outer wall of the clamping plate 4, one side of the pull block 10 is fixedly connected to one end of the pull rope 14, the other end of the pull rope 14 is fixedly connected to one side of the connecting block 16, and one end of the connecting block 16 is fixedly connected to the side wall of the moving block 13.

[0033] More specifically, when the moving block 13 moves, it will move the connecting block 16 along with it. While the connecting block 16 moves, it will pull one end of the pull rope 14. The other end of the pull rope 14 is connected to the pull block 10, which is connected to the clamping plate 4. Since the clamping plate 4 is hinged to the folding platform 1, when the pull rope 14 moves, it will pull the pull block 10 and the clamping plate 4 upwards and hinge them together.

[0034] like Figure 2 As shown, a rack 12 is fixedly connected to the side of the indentation plate 3 near the column 2, and the rack 12 meshes with the gear 11.

[0035] More specifically, by setting the rack 12, when the crease plate 3 is pressed down, the gear 11 does not need to be manually rotated. When the rack 12 is pressed down and contacts the gear 11, the gear 11 can be rotated by meshing. Thus, while the crease plate 3 presses the corrugated cardboard, the two clamps 4 can be automatically lifted up, which is more convenient and time-saving.

[0036] like Figures 1-6As shown, the distance adjustment assembly includes a push plate 5 and a threaded rod 7. The push plate 5 is located inside the adjustment cavity 401. The upper and lower surfaces of the push plate 5 are slidably connected to the inner wall of the adjustment cavity 401. The middle part of the upper surface of the push plate 5 is fixedly connected to the lower end of the threaded rod 7. The upper end of the threaded rod 7 passes through the sliding opening 402.

[0037] More specifically, since different corrugated cardboards require different crease locations, but the creases for the same batch of corrugated cardboard are mostly the same, it is only necessary to adjust the distance at the beginning.

[0038] The specific adjustment method is as follows: measure the distance in advance (of course, you can also set the scale line on the clamping plate 4), then slide the threaded rod 7 in the sliding port 402. While the threaded rod 7 is sliding, the push plate 5 will move together in the adjustment cavity 401 in the same direction, thereby achieving the effect and purpose of distance adjustment.

[0039] like Figures 1-6 As shown, a threaded ring 6 is threadedly connected to the outer wall of one end of the threaded rod 7 that passes through the sliding port 402. The bottom surface of the threaded ring 6 abuts against the upper surface of the clamping plate 4.

[0040] More specifically, by setting the threaded ring 6, after the push plate 5 and the threaded rod 7 are moved to a suitable distance, the threaded ring 6 can be rotated. After the threaded ring 6 rotates, the bottom surface of the threaded ring 6 abuts against the upper surface of the clamping plate 4, and thus the threaded rod 7 and the push plate 5 can be fixed in a specific position within the slide 402 by friction.

[0041] like Figure 5 and Figure 6 As shown, the adjustment cavity 401 has an anti-detachment groove 403 on the side near the slide 402, and an anti-detachment block 17 is fixedly connected to the upper surface of the push plate 5. The outer wall of the anti-detachment block 17 is slidably connected to the inner wall of the anti-detachment groove 403.

[0042] More specifically, because the threaded rod 7 is cylindrical, it is very likely to rotate within the slide 402, which could cause the push plate 5 to tilt within the adjustment cavity 401. This could lead to the corrugated cardboard tilting. To avoid this, by setting the anti-detachment groove 403 and the anti-detachment block 17, the threaded rod 7 and the push plate 5 can be limited to moving in a straight line along the anti-detachment groove 403, without rotation.

[0043] 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.
