Corrugated board creasing thin-blade machine

The invention discloses a corrugated board creasing thin-blade machine, which comprises a creasing part and a thin-blade slitting part. The front and back of the creasing part is connected with the front and back of the thin-blade slitting part; the creasing part comprises an upper support, a lower support, an upper sliding plate and a lower sliding plate which are symmetrically arranged on the upper part and the lower part of a machine frame; the upper sliding plate and the lower sliding plate are movably connected with the upper support and the lower support respectively; the upper sliding plate and the lower sliding plate are provided with a main supporting wheel and an initial supporting wheel respectively; the main supporting wheel and the initial supporting wheel are provided with creasing caterpillars; and the main supporting wheel is connected with a power device. The creasing caterpillars on the upper sliding plate and the lower sliding plate of the creasing part are symmetrically arranged to realize caterpillar type oblique included angle line contact creasing one-time forming and dual uses of longitudinal standard slitting of a thin blade. The machine has the advantages of simple technical process, high-efficiency and quick creasing forming and high production efficiency. The line contact creasing forming of the creasing caterpillars replaces point contact creasing of round pair wheels, so that corrugated boards are not easy to damage and have good forming quality, and the yield of the corrugated boards is greatly improved.
