Description

Technical Field

[0001] This utility model relates to the field of flattening technology, and in particular to a folding and flattening device for printed color boxes. Background Technology

[0002] Printed color boxes refer to paper packaging boxes that have undergone printing processes and are decorated with colorful graphics and text. They are widely used in product packaging, gift boxes, retail displays, and other scenarios. After the edges of the printed color boxes are folded, they need to be flattened to reduce the overall volume of the box for storage or transportation. Flattening is usually done one box at a time using a pressing plate, which results in slow processing efficiency. To speed up the flattening process, some boxes are stacked, which can easily cause the printed color boxes to tip over. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where stacking and flattening can easily cause printed color boxes to tip over, and to propose a folding and flattening device for printed color boxes.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a folding and flattening device for printed color boxes, including a base plate, a worktable connected to the base plate, four through slots on the worktable, a movable column in each of the four through slots, a connecting block fixedly connected to each of the four movable columns, a spring abutting the lower end of each of the four connecting blocks, the four springs being connected to the base plate through a connecting mechanism, a connecting frame fixedly connected to the worktable, a telescopic rod fixedly connected to the connecting frame, and a pressure plate fixedly connected to the telescopic rod.

[0006] Preferably, the telescopic rod is a hydraulic telescopic rod.

[0007] Preferably, a fixing plate is fixedly connected to each of the four springs, a T-shaped limiting block is fixedly connected to the fixing plate, a T-shaped limiting groove is provided on the base plate, and the T-shaped limiting block is slidably disposed in the T-shaped limiting groove.

[0008] Preferably, a rotating shaft is rotatably connected to the base plate via a bearing, and a first stop block is fixedly connected to the rotating shaft, the first stop block abutting against the T-shaped limiting block.

[0009] Preferably, the bearing is a thrust ball bearing.

[0010] Preferably, a support block is fixedly connected to the base plate, and the support block supports the first stop block.

[0011] Preferably, each of the four movable columns is fixedly connected to a second stop, and the second stop is located above the worktable.

[0012] Preferably, the movable column is located directly below the pressure plate.

[0013] The present invention provides a folding and flattening device for printed color boxes, which has the following advantages: by using four movable columns to form a rectangular structure, the printed color box is limited and prevented from tipping over during flattening, thus ensuring the flattening process. Furthermore, by moving the movable columns together with the pressure plate during flattening, relative movement between the movable columns and the pressure plate is prevented, avoiding wear and tear and extending the service life of the pressure plate and the movable columns.

[0019] 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.

[0020] Example: Refer to Figure 1-4A folding and flattening device for printed color boxes includes a base plate 5, a worktable 4 connected to the base plate 5, four through slots 15 on the worktable 4, and a movable column 6 installed in each of the four through slots 15. The movable column 6 is located directly below a pressure plate 1, and a connecting block 14 is fixedly connected to each of the four movable columns 6. The lower end of each of the four connecting blocks 14 abuts against a spring 8. After flattening, the spring 8 is used to reset the movable column 6. The four springs 8 are connected to the base plate 5 through a connecting mechanism. A connecting frame 2 is fixedly connected to the worktable 4. A telescopic rod 3 is fixedly connected to the frame 2, and a pressure plate 1 is fixedly connected to the telescopic rod 3. By using four movable columns 6 to form a rectangular structure, the printed color box inside is limited, preventing the printed color box from tipping over during flattening, thus ensuring the flattening process. Furthermore, by moving the movable columns 6 together with the pressure plate 1 during flattening, relative movement between the movable columns 6 and the pressure plate 1 is prevented, avoiding wear between the movable columns 6 and the pressure plate 1, and helping to extend the service life of the pressure plate 1 and the movable columns 6.

[0021] Example 2: In Example 1, after long-term operation, spring 8 reaches its fatigue life, which easily leads to damage and makes replacement inconvenient. (Refer to...) Figure 1-4 As another preferred embodiment of this utility model, based on embodiment 1, a fixing plate 7 is fixedly connected to the four springs 8, and a T-shaped limiting block 9 is fixedly connected to the fixing plate 7. A T-shaped limiting groove is opened on the bottom plate 5, and the T-shaped limiting block 9 is slidably disposed in the T-shaped limiting groove. By moving the T-shaped limiting block 9 out of the T-shaped limiting groove, the fixing plate 7 is moved out and removed, and the entire spring 8 is replaced, which is conducive to convenient and quick operation.

[0022] A rotating shaft 12 is rotatably connected to the base plate 5 via a bearing. A first stop 10 is fixedly connected to the rotating shaft 12. The first stop 10 abuts against the T-shaped limit block 9. The first stop 10 is used to limit the T-shaped limit block 9, preventing the T-shaped limit block 9 from moving out of the T-shaped limit groove during operation.

[0023] Because the bearing is subjected to axial force, a thrust ball bearing is used to handle the axial force load.

[0024] Example 3: Reference Figure 1-3 As another preferred embodiment of this utility model, based on embodiment 2, a support block 11 is fixedly connected to the base plate 5. The support block 11 supports the first stop block 10 so that the first stop block 10 abuts and limits the T-shaped limiting block 9. When it is necessary to release the limit, the first stop block 10 is rotated to release the abutment of the T-shaped limiting block 9.

[0025] Each of the four movable columns 6 is fixedly connected with a second stop 13. The second stop 13 is located above the worktable 4. The second stop 13 is used to limit the movement of the movable columns 6 and prevent the movable columns 6 from moving downward and getting out of the through groove 15.

[0026] Example 4: Reference Figure 1-4 As another preferred embodiment of this utility model, based on embodiment 3, the telescopic rod 3 is a hydraulic telescopic rod, and a pressure sensor is provided on the lower surface of the pressure plate 1. The telescopic rod 3 is controlled by a controller, which is installed on the workbench 4 and connected to the pressure sensor signal to control the pressure of flattening, so as to prevent excessive pressure from causing damage to the cardboard box.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
