Description

Technical Field

[0001] This utility model relates to the field of packaging paperboard production technology, specifically to a packaging paperboard creasing device. Background Technology

[0002] Creasing of packaging paperboard is a key processing technology in packaging production. It refers to the process of applying pressure to the surface of packaging substrates such as corrugated paperboard and cardboard through the rollers or pressure head of the creasing device to form a creasing line of uniform depth. The core function of this creasing line is to allow the paperboard to bend precisely along the predetermined trajectory when it is folded and formed in the subsequent process, so as to avoid problems such as cracking, warping or irregular creases caused by forced folding.

[0003] Conventional creasing devices often employ a fixed single-wheel structure. When dealing with thick corrugated cardboard, the concentrated pressure can easily lead to creasing damage and uneven depth. When processing thin cardboard, the creasing is often too shallow or the position is misaligned, making it difficult to meet the processing needs of different cardboard sizes. Furthermore, dust and paper scraps easily remain on the surface of corrugated cardboard, and these impurities can cause creasing defects during the creasing process, affecting the processing quality. To address these issues, the inventors have proposed a packaging cardboard creasing device to solve these problems. Utility Model Content

[0026] By adopting the above technical solutions, the inclined exhaust duct 721 can accurately blow away dust, paper scraps and other impurities from the surface of the cardboard, while the vertical exhaust duct 722 can provide downward stable air pressure to stabilize the position of the cardboard.

[0029] The limiting plate 68 has two symmetrically distributed limiting grooves 69, and the limiting bolt 66 is inserted into the limiting groove 69. The outer wall of the limiting bolt 66 is fitted with a spring 67, and the two ends of the spring 67 are fixedly connected to the inner wall of the limiting frame 65 and the limiting bolt 66, respectively.

[0030] By adopting the above technical solution, the spring 67 pushes the limit bolt 66 into the limit groove 69 to limit and lock the flip frame 63.

[0031] Fixed shafts 610 are fixedly installed on both sides of the outer wall of the support frame 61, and the flip frame 63 is rotatably installed on the fixed shafts 610.

[0032] By adopting the above technical solution, the flipping frame 63 is rotated around the fixed axis 610.

A drive motor 75 is fixedly installed on the outer wall of the fixed frame 73, and the drive end of the drive motor 75 is rotatably connected to the fixed frame 73.

A conveying hose 77 is connected through the top of the lifting plate 5, and the other end of the conveying hose 77 is connected through the exhaust end of the fixed frame 73.

[0034] By adopting the above technical solution, the drive motor 75 can drive the impeller 74 to rotate at high speed, thereby stably outputting high-speed airflow and providing reliable power support for cleaning the paper surface before creasing.

[0035] The lifting plate 5 is slidably connected to the sliding frame 4 via a slide rail. The lifting electric cylinder 8 is fixedly installed on the sliding frame 4, and the drive end of the lifting electric cylinder 8 is fixedly connected to the top of the lifting plate 5.

[0036] By adopting the above technical solution, the lifting electric cylinder 8 pushes the sliding frame 4 to slide stably vertically under the guidance of the slide rail.

[0037] A servo motor 33 is fixedly installed on one side of the top of the bracket 2, and the drive end of the servo motor 33 is connected to the lead screw 31 through a coupling.

[0038] By adopting the above technical solution, the servo motor 33 drives the lead screw 31 to rotate stably.

[0039] Working principle: In the actual corrugated cardboard creasing process, firstly, the corrugated cardboard is laid flat on the surface of the workbench 1, and the edges of the cardboard are aligned with the positioning reference line of the workbench 1. The roller mode is adjusted according to the actual thickness of the corrugated cardboard. In the initial state, the limit bolt 66 is inserted into the bottom limit groove 69. At this time, the flip frame 63 tilts upward and only the first roller 62 is used, which is a single-wheel mode. When the corrugated cardboard is thicker, the limit bolt 66 is manually pulled outward. The limit bolt 66 compresses the spring 67, causing the limit bolt 66 to disengage from the bottom limit groove 69. The flip frame 63 is controlled to rotate around the fixed shaft 610 on the outer wall of the support frame 61, so that the limit bolt 66 is aligned with the upper limit groove 69. After the limit bolt 66 is released, the spring 67 pushes the limit bolt 66 into the upper limit groove 69, locking the flip frame 63. At this time, the second roller 64 is flush with the first roller 62, which is a double-wheel mode.

[0040] Then, the drive motor 75 is turned on, and the drive motor 75 drives the impeller 74 to rotate at high speed to generate high-speed airflow. The airflow enters the air guide frame 72 through the delivery hose 77 and the air guide pipe 76, and is discharged from the inclined exhaust duct 721 and the vertical exhaust duct 722 respectively. The inclined exhaust duct 721 blows out high-pressure airflow to sweep away dust and paper scraps on the surface of the cardboard. The vertical exhaust duct 722 outputs a steady flow air pressure to press the cardboard down and prevent the cardboard from shifting during subsequent creasing.

[0041] The lifting cylinder 8 is activated, and its drive end pushes the lifting plate 5 to slowly descend, causing the rollers of the creasing adjustment component 6 to contact the cardboard surface. Subsequently, the servo motor 33 is activated, driving the lead screw 31 to rotate. During rotation, the lead screw 31 drives the sliding frame 4 to slide at a constant speed along the slide rail of the bracket 2 via the guide block 32. In single-wheel mode, the first roller 62 applies pressure to the cardboard alone, and the creasing is completed as the sliding frame 4 moves linearly. In double-wheel mode, the first roller 62 and the second roller 64 work together to distribute the pressure. After the sliding frame 4 slides to the end of its stroke, the lifting cylinder 8 drives the lifting plate 5 to rise again, and the servo motor 33 drives the sliding frame 4 to reset. The creasing corrugated cardboard is then removed, and the clarity, absence of damage, and positional accuracy of the creasing are checked. After confirmation that it is qualified, the subsequent folding process begins.

[0042] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
