Abstract

The invention provides a paper reverse-curling device and a paper cutting machine. Paper leveling quality is improved. The paper reverse-curling device comprises at least three transition rollers which are sequentially arranged at intervals from front to back and further comprises at least two curling shafts which are sequentially arranged at intervals from front to back; one curling shaft is arranged between any two adjacent transition rollers, and first contact points used for being in contact with paper so as to allow paper to be wound around the first contact points are arranged on the transition rollers; the curling shafts are provided with second contacts which are used for being in contact with paper so as to allow the paper to be wound around the second contacts; the included angle theta formed between the connecting line of each second contact point and the adjacent first contact point on the front side of the second contact point and the connecting line of the second contact point and the adjacent first contact point on the rear side of the second contact point is larger than 0 degree and smaller than 180 degrees; and the included angle theta formed between the second contact on the front side and two corresponding adjacent first contact points is larger than the included angle theta formed between the second contact point on the rear side and two corresponding adjacent first contact points.

Description

technical field [0001] The invention relates to the field of paper processing, in particular to a paper decurling device and a paper cutter with the same. Background technique [0002] In the paper converting industry, raw paper is usually wound into rolls for storage and transportation. In the secondary processing, such as cutting, the raw paper is unrolled and then enters the paper cutter for cutting. However, the unwound paper is curled, resulting in poor or impossible cutting. Due to this reason, a large number of defective products are caused and secondary processing is affected, and the waste is huge. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a paper decurling device and a paper cutter, which improves the leveling quality of paper. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] A pap...
