Description

Technical Field

[0001] The utility model relates to the technical field of paper wrinkle-proof cutting, in particular to a paper wrinkle-proof cutting mechanism for a paper automatic production line. Background Art

[0002] The paper output from the paper roll is generally large, which is not conducive to packaging and subsequent use. Therefore, the paper needs to be cut. In order to prevent the paper from wrinkling after cutting, the prior art generally adopts the method of applying a positioning device for cutting. However, this method is difficult to achieve online continuous cutting. For example, the utility model patent with patent publication number CN213946554U discloses a paper production splitting device with an anti-wrinkle structure. The paper production splitting device with an anti-wrinkle structure is provided with a cutting mechanism, that is, the piston rod of the cylinder drives the connecting seat to move downward, and the connecting seat drives the connecting shafts and rollers on both sides to move downward. The rollers contact the surface of the paper and slide along the paper at the same time. While the rollers slide along the paper, the paper on both sides of the cutter are smoothed. When the cutter moves to the paper, the paper can be cut. However, with the mechanical vibration, the paper vibration will cause displacement and wrinkles to occur, resulting in skewed cutting during cutting. The cut paper is difficult to be correctly positioned on the subsequent stacking and conveying mechanism, which is easy to cause stacking misalignment or overlapping conveying. Utility Model Content
