Description

Technical Field

[0001] This utility model relates to the field of box gluing machine technology, specifically a fully automatic box gluing machine. Background Technology

[0002] In the packaging and printing industry, box gluing is the final and crucial step in cardboard box forming, and its quality directly affects the product's aesthetics and practicality. Traditional box gluing machines manually fix the crease blade height using bolts, washers, or lead screws. This requires stopping the machine to disassemble and reassemble components when the cardboard thickness changes.

[0003] When using a crease cutter to press creases into cardboard, if the creases are too shallow, folding will be difficult and the cardboard box will not be properly shaped; while if the creases are too deep, the paper fibers may break and the glue may not penetrate well, resulting in an increased scrap rate.

[0004] Patent CN220826355U discloses a gluing machine for packaging printing, which realizes the limited conveying of cardboard of different sizes. Through the cooperation of the first screw and the second screw, the dispensing machine can perform the effect of dispensing glue on cardboard of different thicknesses and sizes at different positions.

[0005] The aforementioned patents solved the problem of not being able to apply glue to cardboard of different thicknesses and at different locations on the cardboard. However, there is still room for optimization in adjusting the pressing depth of the crease knife. This application solves the problem of automatically adjusting the pressing depth of the crease knife according to the thickness of the cardboard, thus solving the problem of traditional crease knives relying on manual adjustment by mechanical cams or lead screws with a fixed height.

[0006] Therefore, this application proposes a fully automatic box-gluing machine that automatically adjusts the pressing depth of the crease cutter. Utility Model Content

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Example 1, please refer to Figure 1 and Figure 4 A fully automatic box gluing machine includes a box gluing machine body 1. A fixed bracket 2 is fixedly connected to the top of the outer wall of the box gluing machine body 1. A servo motor 3 is symmetrically fixedly connected to the top of the outer wall of the fixed bracket 2. A rotating rod 17 is movably installed on the bottom of the outer wall of the servo motor 3. A lifting plate 4 is threadedly connected to the outer wall of the rotating rod 17. A crease knife 5 is slidably connected to the bottom of the outer wall of the lifting plate 4. An electric push rod 6 is symmetrically fixedly connected to the outer wall of the fixed bracket 2. A clamping plate 7 is fixedly connected to the side wall of the electric push rod 6. A central control screen 31 is fixedly connected to the side wall of the box gluing machine body 1. The central control screen 31 is connected to the servo motor 3 via Bluetooth.

[0027] Furthermore, when the cardboard is conveyed by the main body 1 of the gluing machine, the conveying stops when the cardboard reaches below the crease knife 5. At the same time, the electric push rod 6 is activated, which drives the clamping plate 7 to move. The clamping plate 7 gradually approaches the cardboard to clamp and fix it. The servo motor 3 is activated, which drives the rotating rod 17 to rotate forward. The rotating rod 17 drives the lifting plate 4 to move downward, and the lifting plate 4 drives the crease knife 5 to move downward. The crease knife 5 approaches the cardboard and presses a crease on it. The central control screen 31 automatically adjusts the pressing depth of the crease knife 5 according to the cardboard specifications pre-input by the operator and the thickness of the cardboard by driving the servo motor 3. This eliminates the need for repeated manual adjustments of mechanical parts, solving the problem of the crease knife 5 pressing too deeply, causing punctures or cracks, and solving the problem of insufficient pressing due to the cardboard being too thick, resulting in unclear creases and affecting the forming accuracy. It also avoids the impact of manual machine adjustment errors on the finished product, ensuring that the crease position and strength of cardboard of the same specification in different batches are consistent.

[0028] Example 2, please refer to Figure 1 , Figure 2 and Figure 3A fully automatic box gluing machine includes a main body 1. The main body 1 is equipped with a fixed bracket 2, a servo motor 3, a rotating rod 17, a lifting plate 4, a crease knife 5, an electric push rod 6, a clamping plate 7, and a central control screen 31. The central control screen 31 is connected to the servo motor 3 via Bluetooth. First lifting blocks 8 are symmetrically fixedly connected to the outer wall of the lifting plate 4. The fixed bracket 2 is movably fitted onto the outer wall of the first lifting block 8. A first toothed plate 9 is fixedly connected to the side wall of the first lifting block 8. A rotating gear 11 is meshed with the side wall of the first toothed plate 9. The rotating gear 11 is connected to the fixed bracket 2 via a rotating shaft. The rotating gear 11 is meshed with the side wall of the fixed bracket 2. A second toothed plate 14 is installed, and a second lifting block 13 is fixedly connected to the side wall of the second toothed plate 14. A fixed bracket 2 is movably fitted on the outer wall of the second lifting block 13. A translation plate 15 is fixedly connected to the side wall of the second lifting block 13. A support plate 16 is fixedly connected to the top of the outer wall of the translation plate 15. A drive motor 18 is fixedly connected to the side wall of the support plate 16. A rotating shaft 29 is movably installed on the side wall of the drive motor 18. A displacement block 20 is threadedly connected to the outer wall of the rotating shaft 29. The translation plate 15 is movably fitted on the outer wall of the displacement block 20. A connecting frame 21 is fixedly connected to the bottom of the outer wall of the displacement block 20. A cleaning roller 22 is connected to the connecting frame 21 through a rotating shaft.

[0029] Furthermore, when the cardboard is conveyed by the main body 1 of the gluing machine, the conveying stops when the cardboard reaches below the cleaning roller 22. At the same time, the electric push rod 6 is activated, which drives the clamping plate 7 to clamp and fix the cardboard. The servo motor 3 is activated, which drives the rotating rod 17 to rotate in the opposite direction. The rotating rod 17 drives the lifting plate 4 to move upward, which in turn drives the first lifting block 8 to move upward. The first lifting block 8 drives the first toothed plate 9 to move upward, which in turn drives the rotating gear 11 to rotate. The rotating gear 11 drives the second toothed plate 14 to move, which in turn drives the second lifting block 13 to move downward. The second lifting block 13 drives the translation plate 15 to move downward, which in turn drives the support plate 16, drive motor 18, rotating shaft 29, connecting frame 21, displacement block 20, and cleaning roller 22 to move downward, so that the cleaning roller 22 and the... When the cardboard contacts the servo motor 3, the servo motor 3 is turned off and then turned on. The servo motor 3 drives the rotating shaft 29 to rotate, the rotating shaft 29 drives the displacement block 20 to move, the displacement block 20 drives the connecting frame 21 to move, and the connecting frame 21 drives the cleaning roller 22 to roll on the cardboard, thereby cleaning the surface of the cardboard and eliminating the interference of impurities on the crease formation of the cardboard. This prevents dust, paper scraps, or oil stains on the cardboard surface from hindering the downward pressure of the crease knife 5, which could lead to blurred, broken, or uneven crease lines. It also prevents the crease knife 4 from locally squeezing particles when it presses down, which could cause the cardboard to be punctured or cracked. The thickness of the cardboard pre-input by the operator on the central control screen 31 is used to drive the servo motor 3 to ensure that the cleaning roller 22 is in full contact with the cardboard surface. The cleaning roller 22 does not squeeze the cardboard excessively, which could lead to the cardboard being damaged. This avoids the cleaning being incomplete due to insufficient pressure, and ensures that the cleaning force is uniform and stable.

[0030] Example 3, please refer to Figure 1 and Figure 4 A fully automatic box-gluing machine, wherein a connecting plate 23 is fixedly connected to the top of the outer wall of the crease knife 5, and a lifting plate 4 is slidably connected to the outer wall of the connecting plate 23. The top of the outer wall of the lifting plate 4 has equidistantly spaced positioning grooves 26, and the outer wall of the connecting plate 23 has symmetrically spaced locking grooves 24, which are movably fitted onto the outer wall of the fixing bolt 25. The outer wall of the fixing bolt 25 is movably fitted with the positioning grooves 26. The bottom of the outer wall of the lifting plate 4 has a sliding groove 30, which is movably fitted onto the outer wall of the connecting plate 23. The sliding groove 30 communicates with the positioning grooves 26. The side wall of the sliding groove 30 has a limiting groove 28, and the outer wall of the connecting plate 23 is symmetrically fixedly connected with a limiting plate 27. The limiting groove 28 is movably fitted onto the outer wall of the limiting plate 27.

[0031] Furthermore, when it is necessary to adjust the position of the crease on the cardboard, unscrew the fixing bolt 25 on the lifting plate 4. At this time, the crease knife 5 can be moved to adjust its position. The crease knife 5 drives the connecting plate 23 to move within the sliding groove 30. The connecting plate 23 drives the limiting plate 27 to move within the limiting groove 28. The limiting groove 28 prevents the limiting plate 27 and the connecting plate 23 from shifting during movement and prevents the connecting plate 23 from falling off the lifting plate 4. Before completing the position adjustment of the crease knife 5, it is necessary to ensure that the positioning groove 26 and the locking groove 24 are on the same vertical line. When the fixing bolt 25 is screwed in, the fixing bolt 25 can be screwed into the locking groove 24 through the positioning groove 26, thereby fixing the crease knife 5 and the connecting plate 23 and adjusting the position of the crease knife 5. This allows the equipment to adapt to different production needs and improves the adaptability of the equipment.

[0032] Example 4, please refer to Figure 1 and Figure 2 A fully automatic box gluing machine, wherein the main body 1 of the box gluing machine is provided with a fixed bracket 2, a servo motor 3, a rotating rod 17, a lifting plate 4, a crease knife 5, and a cleaning roller 22. The fixed bracket 2 is provided with a first toothed plate 9, a rotating gear 11, and a second toothed plate 14. The first lifting block 8 is movably fitted on the outer wall of the first positioning post 10, and the second lifting block 13 is movably fitted on the outer wall of the second positioning post 12. The fixed bracket 2 is fixedly connected to the side walls of the first positioning post 10 and the second positioning post 12. The outer wall of the translation plate 15 is provided with a displacement groove 19, which is movably fitted on the outer wall of the displacement block 20.

[0033] Furthermore, the servo motor 3 starts, driving the rotating rod 17 to rotate. The rotating rod 17 drives the lifting plate 4 to move, and the lifting plate 4 drives the first lifting block 8 to move. The first lifting block 8 moves along the first positioning post 10, which prevents the first lifting block 8 from misaligning during its movement. The first lifting block 8 drives the first toothed plate 9 to move, which in turn drives the rotating gear 11 to rotate. The rotating gear 11 drives the second toothed plate 14 to move, and the second toothed plate 14 drives the second lifting block 13 to move. The second lifting block 13 moves along the second positioning post 12, which prevents the second lifting block 13 from misaligning during its movement. By setting the first positioning post 10 and the second positioning post 12, it is ensured that the first lifting block 8 and the second lifting block 13 will not deviate during their movement, thereby ensuring that the crease knife 5 and the cleaning roller 22 will not deviate during their movement, thus ensuring the accuracy of the crease and the cleaning effect.

[0034] Example 5, please refer to Figure 1 , Figure 2 and Figure 3 An automatic box gluing machine includes a main body 1. The main body 1 is equipped with a fixed bracket 2, a servo motor 3, a rotating rod 17, a lifting plate 4, a crease knife 5, an electric push rod 6, a clamping plate 7, and a central control screen 31. The central control screen 31 is connected to the servo motor 3 via Bluetooth. A first lifting block 8 is symmetrically fixedly connected to the outer wall of the lifting plate 4. The fixed bracket 2 is movably fitted onto the outer wall of the first lifting block 8. A first toothed plate 9 is fixedly connected to the side wall of the first lifting block 8. A rotating gear 11 is meshed with the side wall of the first toothed plate 9. The rotating gear 11 is connected to the fixed bracket 2 via a rotating shaft. A second toothed plate 14 is meshed with the side wall of the rotating gear 11. A second lifting block 13 is fixedly connected to the side wall of the second toothed plate 14. The fixed bracket 2 is movably fitted onto the outer wall of the second lifting block 13. A translation plate 15 is fixedly connected to the side wall of the second lifting block 13. A support plate 16, a drive motor 18, a rotating shaft 29, a displacement block 20, a connecting frame 21, and a cleaning roller 22 are provided on the translation plate 15.

[0035] Furthermore, when the main body 1 of the gluing machine conveys multiple cardboards, when the cardboard cleaned by the cleaning roller 22 is conveyed to below the crease knife 5, and at the same time the cardboard that has not been cleaned moves to below the cleaning roller 22, the conveying stops, the electric push rod 6 is activated, the electric push rod 6 drives the clamping plate 7 to clamp two cardboards, the servo motor 3 is activated, the servo motor 3 drives the rotating rod 17 to rotate forward, the rotating rod 17 drives the lifting plate 4, the first lifting block 8, and the crease knife 5 to move downward, the crease knife 5 presses creases on the cleaned cardboard, and the machine is activated again, causing the servo motor 3 to rotate. When lever 17 rotates in the opposite direction, it causes the lifting plate 4, the first lifting block 8, and the crease knife 5 to move upwards. The crease knife 5 moves away from the cleaned cardboard. The first lifting block 8 causes the first toothed plate 9 to move upwards. The first toothed plate 9 drives the rotating gear 11. The rotating gear 11 drives the second toothed plate 14 to move downwards. The second toothed plate 14 drives the second lifting block 13 to move downwards. The second lifting block 13 drives the translation plate 15, the support plate 16, the drive motor 18, the rotating shaft 29, the connecting frame 21, the displacement block 20, and the cleaning roller 22 to move downwards, causing the cleaning roller... When the cleaning roller 22 contacts the cardboard, the servo motor 3 is activated, causing the cleaning roller 22 to clean the uncleaned cardboard. By controlling the servo motor 3, the rotating rod 17 rotates periodically in both directions. This allows the main body 1 of the gluing machine to transport multiple cardboards. After the crease knife 5 presses out a crease on one cardboard, the crease knife 5 returns to its upward position, while the cleaning roller 22 moves downward to clean the next uncleaned cardboard to be creased. After cleaning, the electric push rod 6 is activated to release the clamping and fixing of the cardboard, allowing the cardboard to be transported simultaneously. The servo motor 3 resets the cleaning roller 22 upwards and moves the crease knife 5 downwards. This allows the crease knife 5 to press out creases after the next piece of cardboard is passed under the crease knife 5 and clamped by the clamping plate 7. This achieves continuous cleaning of the cardboard surface and pressing out creases, improving production efficiency. It also avoids the cleaning roller 22 and the crease knife 5 moving down or up synchronously, which would cause the crease knife 5 to continuously press on the cardboard while the cleaning roller 22 is cleaning it. This would cause the ink sprayed on the cardboard surface to be squeezed and spread, forming rough edges or blurred dots, affecting the appearance quality and potentially damaging the cardboard fiber structure.

[0036] Working principle: Unscrew the fixing bolt 25 on the lifting plate 4, move the crease knife 5 so that the locking groove 24 and the required positioning groove 26 are on the same vertical line, screw the fixing bolt 25 into the positioning groove 26 and the locking groove 24 to adjust the position of the crease knife 5.

[0037] The electric push rod 6 drives the clamping plate 7 to clamp the cardboard, the servo motor 3 drives the rotating rod 17 to rotate in the forward direction, the crease knife 5 moves downward to press creases on the cardboard, the servo motor 3 drives the rotating rod 17 to rotate in the reverse direction, and the cleaning roller 22 cleans the cardboard that is about to be creased downward.

[0038] The electric push rod 6 drives the clamping plate 7 to release the cardboard from the clamping plate. The servo motor 3 causes the cleaning roller 22 to move upward. The main body 1 of the gluing machine drives the cardboard to be transported, so that the cardboard cleaned by the cleaning roller 22 moves to below the crease knife 5, and the next cardboard moves to below the cleaning roller 22.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
