Background Art

[0002] At present, with the continuous improvement of the decoration printing and packaging standards of cigarette labels, the beauty of color box products has been continuously improved, and higher and higher requirements are put forward for the appearance of packaging, and the precision requirements of products are getting higher and higher.

[0003] During the working process of cigarette label printing, in order to ensure the reliability of printing and processing, the width of the base paper is generally greater than the width of the final product. This requires that before automatically stacking and packaging after cutting into multiple cigarette label papers of the same size, it is necessary to perform bilateral rough edge cutting on the composite printed cigarette label packaging to achieve the consistency of the size and registration line of multiple papers; in this process, about 3-5 mm wide waste paper edges can be cut off on each side of the paper web. Due to the high-speed operation of the cigarette label packaging production line, the waste paper edges are extremely easy to be wound into the paper roll, which will affect the subsequent slitting of the paper roll, thus causing quality problems.

[0004] Therefore, in the production process of cigarette label paper, it is urgent to quickly and effectively discharge the waste edge strips cut off from both sides of the paper web to maintain the efficient operation of production.
