Description

Technical Field

[0001] This utility model relates to the field of cardboard box production, specifically a cardboard bending device for cardboard box production. Background Technology

[0002] Cardboard boxes are containers made of paper materials, used for product packaging and protection. They are widely used in industries such as electronics, food, beverages, pharmaceuticals, and clothing. During the cardboard production process, bending is required to ensure that the cardboard boxes can be folded and glued according to the predetermined structure during assembly.

[0003] CN220517662U discloses a cardboard bending device, including a worktable. A cardboard pressing mechanism is installed on one side of the worktable, and a cardboard bending mechanism is installed at one edge of the worktable. An adjusting mechanism is provided between the cardboard bending mechanism and the cardboard pressing mechanism, and the cardboard bending mechanism is mounted on the cardboard pressing mechanism through the adjusting mechanism. The worktable of this invention features a cardboard pressing mechanism and a cardboard bending mechanism. The cardboard pressing mechanism can move downwards to press the cardboard onto the worktable, while the cardboard bending mechanism is offset from the worktable. The cardboard bending mechanism can move downwards and bend the portion of the cardboard extending beyond the worktable downwards. Through the cooperation of the cardboard pressing mechanism and the cardboard bending mechanism, the folding position of the corrugated cardboard can be made neat, thereby avoiding problems caused by uneven folding affecting its use.

[0004] However, different packaging cardboards have different bending positions when bent, making it inconvenient to adjust the bending position. In addition, different cardboards have different lengths, and the bending position is easy to shift during the bending process, making it difficult to center and position. Utility Model Content
