Description

Technical Field

[0001] This utility model relates to the field of corrugated paper production technology, specifically a dual-station corrugated paper pressing device. Background Technology

[0002] As an important packaging material, the production quality of corrugated cardboard directly affects the compressive strength and structural stability of the product. Traditional corrugated cardboard bonding devices mostly use upper and lower pressure rollers to apply pressure to multiple layers of corrugated cardboard to achieve bonding. However, this structure has significant technical drawbacks in practical applications. First, the spacing between the upper and lower pressure rollers is usually fixed, which can only accommodate corrugated cardboard of a specific thickness. However, the modern packaging industry has diversified needs, requiring frequent switching between different numbers of layers (such as three-, five-, or seven-layer) or different core paper thicknesses in corrugated cardboard production. Fixed-spacing pressure rollers require manual adjustment or replacement of parts to adapt to different thicknesses, which is cumbersome and results in long downtime, severely restricting production efficiency and making it difficult to meet the needs of flexible production.

[0003] Meanwhile, for multi-layer composite corrugated paper, multiple layers of corrugated paper need to be glued together during production. In order to prevent the corrugated paper from deviating during the gluing process, the corrugated paper needs to be limited by the side plate. The traditional side plate position is fixed, so it can only be used for gluing one type of corrugated paper, making it inconvenient to adjust during use.

[0004] Based on this, a dual-station corrugated paper pressing device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-7 As shown, the dual-station corrugated paper pressing device includes pressing plates 11, two of which are symmetrically arranged. The pressing plates 11 are fixed on the output end of the first electric cylinder 12, which is fixed inside the support frame. The support frame is fixed on the upper end of the mounting box 17. The pressing plates 11 are all located inside the mounting box 17. A partition 16 is provided between the two pressing plates 11, dividing the interior of the mounting box 17 into two processing chambers. A conveyor belt 13 and a conveyor roller 24 are respectively provided at both ends of the processing chamber. The conveyor belt 13 is located below the pressing plates 11. A fixed roller 25 is provided above each of the conveyor rollers 24. Each of the conveyor rollers 24 is provided with a limiting mechanism for limiting the position of the corrugated paper. Each of the conveyor belts 13 is provided with a support mechanism for supporting the upper end of the conveyor belt 13. The limiting mechanism facilitates limiting the position of the corrugated paper conveying, and the support mechanism facilitates clamping the conveyor belt 13 to prevent large deformation of the conveyor belt 13.

[0027] Both ends of the conveyor belt 13 are equipped with drive rollers and transmission rollers. The rotating shafts at both ends of the drive rollers and transmission rollers are respectively rotatably disposed in rotating holes on one side of two retaining plates 22. The other side of each retaining plate 22 is symmetrically provided with fixing tubes. One end of each fixing tube is fixedly connected to the interior of the processing chamber. One rotating shaft of the drive roller extends to the outside of the mounting box 17 and is fixedly connected to the output end of the first motor 14. The first motor 14 is fixedly disposed on one side of the mounting box 17. The two first electric cylinders 12 and the first motor 14 are all electrically connected to the control box 31. The control box 31 is fixedly disposed on the first electric cylinder 14. On the motor 14 side, when it is needed to press the corrugated paper, one end of the corrugated paper is placed on the upper end of the conveyor belt 13. Then, the first motor 14 is started by controlling the control box 31. The first motor 14 drives the drive roller to rotate, and the drive roller drives the conveyor belt 13 to rotate, thereby conveying the corrugated paper. After the corrugated paper moves to the bottom of the pressing plate 11, the control box 31 controls the first electric cylinder 12 to start. The output end of the first electric cylinder 12 drives the pressing plate 11 to start. The pressing plate 11 presses down to press the corrugated paper. At the same time, the two first electric cylinders 12 can work alternately, so that the corrugated paper can be continuously pressed.

[0028] A first connecting shaft is provided between the two fixed rollers 25. A rotating block 26 is rotatably mounted on both the rotating shaft of one end of each fixed roller 25 and the first connecting shaft. A limiting groove is provided on one side of the partition plate 16 and the mounting box 17 at a position corresponding to the rotating block 26. The rotating block 26 at one end of the rotating shaft of each fixed roller 25 is fixedly mounted on the output end of a second electric cylinder 27. The second electric cylinder 27 is fixedly mounted in the mounting hole at the upper end of the limiting groove. A second connecting shaft is provided between the rotating shafts of the two conveying rollers 24. One rotating shaft of one conveying roller 24 is fixedly connected to the output end of a second motor 28. The motor 28 is fixedly mounted on one side of the first motor 14. When it is needed to adjust the distance between the conveying roller 24 and the fixed roller 25, the second electric cylinder 27 is started by controlling the control box 31. The output end of the second electric cylinder 27 drives the rotating block 26 to slide, and the rotating block 26 drives the fixed roller 25 to move, thereby adjusting the distance between the conveying roller 24 and the fixed roller 25. Then, the corrugated paper passes between the conveying roller 24 and the fixed roller 25. The second motor 28 is started, and the second motor 28 drives the two conveying rollers 24 to rotate. The conveying rollers 24 and the fixed roller 25 cooperate to convey the corrugated paper.

[0029] The limiting mechanism includes limiting rings 29, and each of the conveying rollers 24 is symmetrically provided with limiting rings 29. The inner side of the limiting rings 29 is provided with several mounting grooves, and each mounting groove is slidably provided with a stop block 30. The stop block 30 is rotatably located at one end of the first screw. The limiting ring 29 is provided with a threaded hole corresponding to the position of the first screw. One end of the stop block 30 is provided with an anti-slip layer. In use, when it is necessary to convey corrugated paper of different widths, the user uses a tool to rotate the first screw. The first screw drives the stop block 30 to move, so that the stop block 30 moves away from the conveying rollers 24, thereby adjusting the working position of the limiting rings 29.

[0030] The support mechanism includes a support plate 15. Support plates 15 are provided on the inner side of the conveyor belt 13. Limiting frames are symmetrically provided on both sides of the support plate 15. Each limiting frame is slidably disposed within a sliding groove on one side of the retaining plate 22. Extension rods are fixedly provided on both sides of the support plate 15. A first rack 18 is fixedly provided at one end of each extension rod. A first gear meshes with each first rack 18. The first gear is fixedly disposed on a drive shaft. One end of the drive shaft is rotatably connected to the retaining plate 22, and the other end is rotatably connected to the inner side of the processing chamber. A worm gear 19 is fixedly provided on the drive shaft. A worm 20 meshes with the worm gear 19. Rotating plates are rotatably disposed on rotating shafts at both ends of the worm 20. The rotating plates are fixedly disposed within the processing chamber. The worm 20 has a second gear fixedly mounted on one end of its rotating shaft. A second rack 21 meshes with the second gear and is fixedly mounted on one side of the pressing plate 11. In use, when the output end of the first electric cylinder 12 drives the pressing plate 11 to move, the pressing plate 11 drives the second rack 21 to move. Before the pressing plate 11 is tightly attached to the corrugated paper, the second rack 21 meshes with the second gear. The second gear drives the worm 20 to rotate. The worm 20 meshes with the worm wheel 19 to drive the transmission shaft to rotate. The transmission shaft drives the first gear to rotate. The first gear meshes with the first rack 18 to drive the support plate 15 to move. After the second rack 21 separates from the second gear, the upper end of the support plate 15 is tightly attached to the upper end of the inside of the conveyor belt 13, thereby supporting the upper end of the conveyor belt 13.

[0031] A plurality of support rollers 23 are provided at equal intervals between the conveyor belt 13 and the conveyor rollers 24. The plurality of support rollers 23 are rotatably disposed in the processing chamber. The plurality of support rollers 23 are arranged in an arc shape. In use, when the pressing plate 11 presses the corrugated paper, the conveyor rollers 24 continue to convey the corrugated paper, causing the corrugated paper to bend, thereby causing the support rollers 23 to support the corrugated paper.

[0032] An adjusting ring 32 is closely attached to the outer side of the limiting ring 29. The limiting ring 29 has a plurality of second threaded holes arranged in a circular array. The adjusting ring 32 and the limiting ring 29 are fixedly connected by a second screw. In use, it is convenient to adjust the outer diameter of the limiting ring 29 according to the thickness of the corrugated paper.

[0033] The above embodiments disclose a dual-station corrugated paper pressing device. When corrugated paper needs to be pressed, a second motor 28 is started. The second motor 28 drives two conveyor rollers 24 to rotate. The conveyor rollers 24 cooperate with the fixed rollers 25 to convey the corrugated paper. One end of the corrugated paper is placed on the upper end of the conveyor belt 13. Subsequently, the first motor 14 is started via the control box 31. The first motor 14 drives the drive roller to rotate, which in turn drives the conveyor belt 13 to rotate, thus conveying the corrugated paper. After the corrugated paper moves to below the pressing plate 11, the control box 31 controls the first motor 14 to start. The first motor 14 drives the drive roller to rotate, which in turn drives the conveyor belt 13 to rotate, thus conveying the corrugated paper. After the corrugated paper moves to below the pressing plate 11, the control box 31 controls the first motor 14 to start. When cylinder 12 is started, the output end of the first electric cylinder 12 drives the pressing plate 11 to start. The pressing plate 11 drives the second rack 21 to move. Before the pressing plate 11 is tightly attached to the corrugated paper, the second rack 21 meshes with the second gear. The second gear drives the worm 20 to rotate. The worm 20 meshes with the worm wheel 19 to drive the transmission shaft to rotate. The transmission shaft drives the first gear to rotate. The first gear meshes with the first rack 18 to drive the support plate 15 to move. When the second rack 21 separates from the second gear, the upper end of the support plate 15 is tightly attached to the upper end of the inside of the conveyor belt 13, thereby supporting the upper end of the conveyor belt 13.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
