Description

Technical Field

[0001] The utility model relates to the technical field of carton processing equipment, and particularly relates to a flattening device for cartons. Background Art

[0002] As a basic material in the modern logistics and packaging industries, cartons have gradually become the main force in transportation packaging due to their excellent performance and good processability. However, during the production and use of cartons, due to factors such as materials, processes, or transportation, cartons often have problems such as unevenness and deformation, which not only affect the aesthetics of the cartons but also reduce their load-bearing capacity and protective performance. Therefore, during the processing and production of cartons, a flattening machine is needed to flatten the cartons for easy transportation and subsequent use. The existing flattening of cartons mostly relies on manual operation, which has low efficiency and is difficult to meet large-scale production. Moreover, due to the differences in manual operations, it is difficult to ensure the consistency of the flattening effect of cartons.

[0003] Chinese patent document CN221272160U discloses a flattening device for carton processing that is easy to align, including a frame and a flattening operation table. A storage rectangular frame is provided on the surface of the flattening operation table, a safety plate is provided on the front push plate, the front push plate is connected to an electric telescopic rod, a fastening plate is provided on the outer wall of the right side of the storage rectangular frame, an extrusion cylinder is provided at the bottom of the fastening plate, an extrusion rod is provided in the extrusion cylinder, a rectangular extrusion plate is provided at the bottom end of the extrusion rod, a flattening groove is provided at one end of the surface of the flattening operation table, U-shaped cavities are provided on both the front and back sides of the flattening groove, and the safety guard plate extends outside the U-shaped cavity to limit the position of the carton, preventing the carton from sliding during the flattening process and falling off the flattening operation table. However, the above flattening device flattens a stack of cartons, resulting in inconsistent flattening effects for each carton, over-flattening of the top and bottom cartons, and insufficient flattening of the middle cartons. Moreover, the safety guard plate can only limit the position of the lower cartons and cannot limit the position of the upper cartons. In view of the above problems, the utility model proposes a flattening device for cartons. Summary of the Utility Model

[0026] Embodiment

[0027] As Figures 1-4 shown, a flattening device for a carton includes an operating table 1. On both sides of the top of the operating table 1, baffles 2 are fixedly provided. A conveyor belt is fixedly provided between the two baffles 2. Above the conveyor belt 3, there is a flattening mechanism. The flattening mechanism includes a hydraulic cylinder 4, a support plate 5, two limiting plates 6, a first pressing roller 7, a second pressing roller 8, a telescopic rod 10, a motor 11 and an adjusting component. The hydraulic cylinder 4 is vertically arranged outside the baffle 2 through a mounting plate. The support plate 5 is fixedly connected to the telescopic end of the hydraulic cylinder 4. The two limiting plates 6 are slidably arranged on both sides of the bottom of the support plate 5. The rear end of the first pressing roller 7 is rotatably connected to the rear limiting plate 6 through a rotating shaft 9. The front end of the first pressing roller 7 is rotatably connected to the front limiting plate 6 through the telescopic rod 10. The front end of the second pressing roller 8 is rotatably connected to the front limiting plate 6 through the rotating shaft 9. The rear end of the second pressing roller 8 is rotatably connected to the rear limiting plate 6 through the telescopic rod 10. The telescopic rod 10 is rotatably connected to the first pressing roller 7 and the second pressing roller 8 through bearings. The bearings can slide along the axis inside the first pressing roller 7 and the second pressing roller 8. The driving end of the motor 11 is fixedly connected to the rotating shaft 9. The adjusting component is used to adjust the distance between the two limiting plates 6. A collecting mechanism is provided at the discharge end of the conveyor belt 3.

[0028] It should be noted that the flattening operation of the carton is carried out through the set operating table 1, the conveyor belt is used to transport the carton, the folded carton is flattened through the set flattening mechanism, and the flattened carton is collected through the set collection mechanism, which is convenient for subsequent bundling and transportation. Specifically, the hydraulic cylinder 4 is used to adjust the height of the support plate 5, the limit plate 6 is used to limit the carton to prevent the carton from moving during the flattening process, the first pressing roller 7 and the second pressing roller 8 are used to flatten the carton, the telescopic rod 10 is rotatably connected to the first pressing roller 7 and the second pressing roller 8, and at the same time the telescopic rod 10 is telescopic relative to the first pressing roller 7 and the second pressing roller 8. The adjusting component is used to adjust the distance between the two limit plates 6, and can make the two limit plates 6 simultaneously close inwards or simultaneously open outwards. When the distance between the two limit plates 6 becomes shorter, the telescopic rod 10 retracts into the first pressing roller 7 and the second pressing roller 8, that is, the length of the telescopic rod 10 outside the first pressing roller 7 and the second pressing roller 8 is shortened. When the distance between the two limit plates 6 becomes longer, the telescopic rod 10 extends out of the first pressing roller 7 and the second pressing roller 8, that is, the length of the telescopic rod 10 outside the first pressing roller 7 and the second pressing roller 8 increases. The motor 11 drives the first pressing roller 7 and the second pressing roller 8 to rotate through the rotating shaft 9.

[0029] Particularly, the first pressing roller 7 and the second pressing roller 8 are respectively close to the rear limit plate 6 and the front limit plate 6, so that when the first pressing roller 7 and the second pressing roller 8 flatten a carton wider than their own width, the first pressing roller 7 and the second pressing roller 8 can simultaneously take into account the front and rear sides of the carton, ensuring the flattening effect and uniformity of the carton.

[0030] The conveyor belt 3 is a conventional structure, including a driving roller, a driven roller, a supporting roller, a conveyor belt and a motor, and its specific structure and principle will not be elaborated too much in this article.

[0031] In some feasible embodiments, the adjusting component is a bidirectional threaded rod 12. The bidirectional threaded rod is embedded in the groove opened at the bottom of the support plate 5. The bidirectional threaded rod 12 is rotatably connected to the front and rear sides of the groove. The top of the limit plate 6 is threadedly connected to the bidirectional threaded rod 12 through a fixing block. One end of the bidirectional threaded rod 12 passes through the support plate 5 and is provided with a turntable 13. The fixing block at the top of the limit plate 6 is restricted by the groove, so that the fixing block cannot rotate with the bidirectional threaded rod 12 and can only slide along the bidirectional threaded rod 12. Rotating the turntable 13 drives the bidirectional threaded rod 12 to rotate, controlling the two limit plates 6 to simultaneously close inwards or simultaneously open outwards, thereby adjusting the distance between the two limit plates 6 to adapt to cartons of different sizes.

[0032] In some feasible embodiments, the bottom end of the limit plate 6 is lower than the bottom ends of the first pressing roller 7 and the second pressing roller 8, and the distance by which the bottom end of the limit plate 6 extends beyond the bottom ends of the first pressing roller 7 and the second pressing roller 8 is less than the thickness of a single cardboard box, such that the limit plate 6 can limit both sides of the cardboard box and does not interfere with the flattening operation of the first pressing roller 7 and the second pressing roller 8.

[0033] In some feasible embodiments, the collecting mechanism includes a bottom plate 14, a collecting chamber 15, a push plate 17 and a driving assembly. The collecting chamber 15 is fixedly arranged at the bottom of the rear side of the bottom plate 14. An opening is provided at the front side of the collecting chamber 15. The collecting chamber 15 includes three side walls, and the three side walls include a left side wall, a right side wall and a rear side wall. The top of the right side wall is higher than the left side wall and the rear side wall. An opening for the push plate 17 to pass through is provided at the bottom of the rear side wall. The push plate 17 is of an L-shaped structure and is slidably arranged on the bottom plate 14 through the driving assembly. The flattened cardboard box enters the collecting chamber 15 from the discharge end of the conveyor belt 3. The right side wall limits the cardboard box to ensure that the cardboard box can fall from the conveyor belt 3 into the collecting chamber 15. The driving assembly drives the push plate 17 to slide back and forth to push the stacked cardboard boxes to the front side of the bottom plate 14, facilitating bundling and handling by workers.

[0034] Specifically, the horizontal section of the L-shaped structure of the push plate 17 can block the cardboard box above when the push plate 17 pushes the cardboard box, preventing the cardboard box above from falling and jamming the push plate 17, resulting in the inability of the push plate 17 to retract.

[0035] In some feasible embodiments, the collecting mechanism further includes an infrared counter 16. The infrared counter 16 is embedded in the right side wall of the collecting chamber 15. The infrared counter 16 can record the number of cardboard boxes entering the collecting chamber 15. When the number of cardboard boxes reaches a preset value, it controls the push plate 17 to push out towards the cardboard boxes.

[0036] In some feasible embodiments, the driving assembly includes an electric slide rail 18 and a slider 19. The slider 19 is slidably arranged on the electric slide rail 18. The vertical section of the L-shaped structure of the push plate 17 is fixedly arranged on the top of the slider 19. The electric slide rail 18 drives the push plate 17 to move forward to push the cardboard box. After pushing the cardboard box to the designated position, the electric slide rail 18 drives the push plate 17 to return to its original position and wait for the next operation.

[0037] During use, first adjust the distance between the limit plates 6 according to the size of the cardboard box. The cardboard box enters the device from the left feeding end of the conveyor belt 3. The motor 11 drives the first pressing roller 7 and the second pressing roller 8 to flatten the cardboard box. The flattened cardboard box moves to the right along with the conveyor belt 3 and enters the collecting chamber 15 for collection. When the number of cardboard boxes in the collecting chamber 15 reaches the preset value, the push plate 17 pushes the stacked cardboard boxes out of the collecting chamber 15, facilitating bundling and handling by workers.

[0038] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
