It can be understood that one end of the corrugated cardboard 3 is tilted with respect to the other end by arranging the separating board 1 obliquely with the second separating roller 4-2 protruding out of the plane where the first separating roller 4-1 and the third separating roller 4-3 are located. The distance between the corrugated boards 3 is increased at the tilted end, so that the corrugated boards 3 are prevented from being mutually attracted, and the subsequent separation is facilitated.
It can be understood that when the angle of the inclined paper dividing plate 1 is larger, and the height of the plane where the second paper dividing roller 4-2 protrudes out of the first paper dividing roller 4-1 and the third paper dividing roller 4-3 is larger, the space between the corrugated boards 3 at the raised end can be made as large as possible. However, the corrugated cardboard 3 corresponding to the second separation roller 4-2 is excessively stressed due to the excessively large pitch, and embossing is generated, thereby affecting the appearance. Therefore, preferably, the paper separating plate 1 is arranged obliquely and forms an included angle A with the horizontal plane, wherein A is 2-5 degrees. Further, the second separation roller 4-2 is disposed away from the center of gravity 0 of the corrugated cardboard 3 and close to the lower wire pressing plate 5.
