Description

Technical Field

[0001] This utility model relates to a paper box forming machine. Background Technology

[0002] Corrugated top and bottom box is a type of cardboard box made of corrugated cardboard. The cardboard is pre-cut and creasing, and has a long side and a wide side. The long side has a folded lug. During the box forming process, the folded lug on the long side needs to be folded inward. This process is called edge folding.

[0003] Chinese utility patent CN219820775U discloses a folding mechanism for corrugated cardboard boxes. The cardboard is gripped and moves downwards, and the folding lug on the long side is pre-folded by a static folding component. Alternatively, the cardboard is first placed on a support plate, and the folding component performs a pre-folding action. Then, a drive component drives the folding component to press the folding lug completely onto the long side. In production practice, it has been found that when the crease line is too shallow relative to the thickness of the cardboard, the folding lug cannot be accurately bent along the crease line during the folding process. Furthermore, corrugated cardboard may warp due to improper tension control during production, uneven moisture content, temperature and humidity changes during storage and transportation, and material properties, affecting its flatness and consequently the crease and folding of the cardboard box. When making corrugated cardboard boxes, warping of the corrugated cardboard makes folding difficult. Utility Model Content

[0004] In view of the technical problems existing in the background art, the present invention aims to provide a paper box forming machine, which adds a creasing component to deepen the crease line of the long side fold of the cardboard.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This type of paper box forming machine includes a folding mechanism, which includes a paper-supporting component and a folding component. The paper-supporting component includes a paper-supporting element, and the folding component includes a first folding element and a second folding element. The first folding element and the second folding element are disposed on the left and right sides of the paper-supporting component.

The upper cardboard component includes a cardboard suction nozzle, which is mounted on a mounting frame. An elastic element is provided between the cardboard suction nozzle and the mounting frame. The creasing component includes a creasing element, which is disposed on the left and right sides of the mounting frame. When the cardboard suction nozzle moves the cardboard to the paper-supporting component, the creasing element presses down along the crease line of the long side fold of the cardboard to allow the folding component to fold the edge.

[0006] In this solution, the suction nozzle picks up the cardboard, the upper cardboard component delivers the cardboard to the paper support component and presses it down, the elastic component compresses it, the creasing component contacts and deepens the crease line of the long side fold of the cardboard, and the folding component works with the upper cardboard component to complete the pre-fold.

The cardboard feeding component connects the folding mechanism and the forming mechanism. The paper box feeding component connects the forming mechanism and the dust suction component.

[0014] In this solution, the cardboard feeding component delivers the cardboard that has been folded at the folding mechanism to the forming mechanism. The forming mechanism folds the cardboard into a cardboard box. The cardboard box feeding component takes the cardboard box away and delivers it to the dust suction component. The dust suction component sucks up the dust inside the cardboard box through the suction port.

[0015] Preferably, the paper holder includes a fixed plate, a first movable plate, and a second movable plate. The first movable plate is mounted on the first support, which is laterally adjustable. The second movable plate is mounted on the second support, which is also laterally adjustable.

[0036] The power source in this application is a cylinder, an electric motor, etc.

[0037] See appendix Figure 1 4. In an embodiment of this invention, a paper box forming machine includes a folding mechanism 1. The folding mechanism 1 includes a paper-supporting component 2 and a folding component 4. The paper-supporting component 2 includes a paper-supporting part 3. The folding component 4 includes a first folding part 5 and a second folding part 6. The first folding part 5 and the second folding part 6 are disposed on the left and right sides of the paper-supporting part 3. The paper-supporting part 3 is equipped with an upper paperboard component 7 and a creasing component 11. The upper paperboard component 7 is horizontally movable and vertically adjustable. The upper paperboard component 7 includes a suction... The cardboard suction nozzle 8 is mounted on the mounting frame 9. An elastic element 10 is provided between the cardboard suction nozzle 8 and the mounting frame 9. The creasing component 11 includes a creasing element 12. The creasing element 12 and the cardboard suction nozzle 8 are arranged on the left and right sides of the mounting frame 9. The creasing element 12 is located between adjacent cardboard suction nozzles 8. When the cardboard suction nozzle 8 absorbs the cardboard and moves to the paper support component 3, the creasing element 12 is pressed down along the crease line of the long side fold of the cardboard for the folding component 4 to fold the edge.

[0038] In this embodiment, the suction nozzle 8 picks up the cardboard, the upper cardboard component 7 moves horizontally above the paper support component 3, and then presses down. The suction nozzle 8 first presses the cardboard onto the paper support component 3, and the elastic component 10 then compresses so that the creasing component 12 fully contacts and deepens the crease line of the long side fold of the cardboard. Similarly, when the suction nozzle 8 picks up the cardboard, the creasing component 12 can also deepen the crease line of the long side fold of the cardboard. The creasing component 12 and the suction nozzle 8 are arranged on the left and right sides of the mounting frame 9. The creasing component 12 is located between adjacent suction nozzles 8 and is set with the crease line of the long side fold of the cardboard as a reference to ensure the pre-folding and creasing effect. The creasing component 12 targets the middle of the crease line of the long side fold of the cardboard, and the creasing effect is good. The folding component 4 can cooperate with the suction nozzle 8 to pre-fold the long side fold of the cardboard along the crease line during the pressing process, or it can cooperate with the suction nozzle 8 and the creasing component 12 to pre-fold the long side fold of the cardboard along the crease line after creasing.

[0039] This implementation method can solve both the problem of shallow crease lines and the problem of corrugated cardboard warping and difficulty in folding edges when making corrugated top and bottom box boxes.

[0040] In other alternative embodiments, suction nozzles 8 and creases 12 can be added on other sides to ensure stable paperboard transfer and accurate folding along the corresponding crease lines, or creases can be applied to both sides of the crease lines.

[0041] See appendix Figure 1-3The folding component 4 includes a first bracket 13 and a second bracket 15. A first mounting plate 14 is hinged to the first bracket 13. The first mounting plate 14 is provided with a first lifting cylinder 25 and a first fixed guide block. The first lifting cylinder 25 drives the first folding component 5. The first folding component 5 is connected to a first guide rail. The first guide rail cooperates with the first fixed guide block. A second mounting plate 16 is hinged to the second bracket 15. The second mounting plate 16 is provided with a second lifting cylinder 28 and a second fixed guide block 29. The second lifting cylinder 28 drives the second folding component 6. The second folding component 6 is connected to a second guide rail 30. The second guide rail 30 cooperates with the second fixed guide block 29.

[0042] In this embodiment, after the upper cardboard component avoids the impact, the second mounting plate 16 is driven by the cylinder to swing around the hinge point, the second folding member 6 flips the folded ears on the long side of the cardboard, and the second lifting cylinder 28 drives the second folding member 6 to press down to complete the pressing of the folded ears on the long side of the cardboard. Flipping the ears first and then pressing them down results in a good folding effect. The second guide rail 30 and the second fixed guide block 29 cooperate to guide the pressing down of the second folding member 6. The same applies to the first folding member 5.

[0043] In other alternative implementations, the folded part can be directly folded into place to complete the pressing. There are many designs for the folding action, and it is not limited to the first folding and then pressing method in this application.

[0044] See appendix Figure 1 4. The suction nozzle 8 is mounted on the mounting strip 17. The elastic element 10 is connected between the suction nozzle 8 and the mounting strip 17. The mounting strip 17 is adjusted laterally and longitudinally on the mounting frame 9.

[0045] In this embodiment, the position of the mounting strip 17 on the mounting frame 9 is adjusted to adjust the suction nozzle 8 to adapt to different specifications of cardboard, accurately adsorb the side wall part of the cardboard, and set the force point near the crease line of the long side fold.

[0046] See appendix Figure 1 5. It also includes a forming mechanism, a dust-collecting component 19, a paperboard feeding component, and a paper box feeding component. The forming mechanism is used to fold the paperboard to form a paper box. The dust-collecting component 19 has an air intake that is connected to an air source. The paperboard feeding component connects the folding mechanism 1 and the forming mechanism. The paper box feeding component connects the forming mechanism and the dust-collecting component 19. The mounting frame 9 is raised and lowered below the mounting base 31. The mounting base 31, the paperboard feeding component, and the paper box feeding component are all slidably mounted on a conveyor rail. The conveyor rail is located above the folding mechanism 1, the forming mechanism, and the dust-collecting component 19.

[0047] In this embodiment, the cardboard feeding component delivers the cardboard folded by the folding mechanism 1 to the forming mechanism. The forming mechanism folds the cardboard into a paper box. The paper box feeding component takes the paper box away and delivers it to the dust suction component 19. The dust suction component 19 sucks up the dust inside the paper box through the suction port. The cardboard feeding component 7, the cardboard feeding component, and the paper box feeding component all slide along the conveying slide rail, enabling them to move in unison and convey in an orderly manner.

[0048] See appendix Figure 1 3. The paper holder 3 includes a fixed plate 24, a first movable plate 22, and a second movable plate 23. The first movable plate 22 is mounted on the first bracket 13, and the second movable plate 23 is mounted on the second bracket 15. The first movable plate 22 is connected to a first slider 18, and the second movable plate 23 is connected to a second slider 20.

The fixed plate 24 is fixedly disposed, and the first movable plate 22 and the second movable plate 23 are disposed on both sides of the fixed plate 24.

[0049] In this embodiment, the first slider 18 slides on the adjusting slide rail 21, causing the first movable plate 22 to move away from or closer to the fixed plate 24, so that the supporting plate can adapt to support paperboards of different widths. The guide part 33, together with the guide rod 34, guides the sliding of the second slider 20 to ensure stable adjustment. The second movable plate 23 is similar.
