Corrugated board creasing thin-blade machine

Abstract

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 advantagesof 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.

Description

technical field [0001] The invention belongs to the technical field of packaging machinery for producing corrugated cardboard, and in particular relates to a corrugated cardboard creasing thin knife machine. Background technique [0002] At present, in the low-speed, medium-speed and high-speed corrugated cardboard production lines in the domestic and foreign markets, the creasing thin knife machine is an important stand-alone machine for longitudinal creasing and slitting of corrugated cardboard. The creasing part of the creasing thin knife machine includes an upper set of creasing wheels and a lower set of creasing wheels. The two sets of creasing wheels vertically press the corrugated cardboard, that is, the circular creasing wheels form point contact creasing on the cardboard. There are defects such as poor forming effect and easy damage of indentation, which reduces the yield of corrugated cardboard. Under the action of linear speed, the groove-shaped grooves on the c...

Problems solved by technology

The creasing part of the creasing thin knife machine includes an upper set of creasing wheels and a lower set of creasing wheels. The two sets of creasing wheels vertically press the corrugated cardboard, that is, the circular creasing wheels form point contact creasing on the cardboard. There are defects of poor forming effect and easy damage of indentation, which reduces the yield of corrugated cardboard

Under the action of linear speed, groove-shaped grooves are formed on the corrugated cardboard to realize the early process of corrugated cardboard. Due to the influence of raw material paper tension, paper thickness and weight, the indentation quality of the cardboard is poor; usually to avoid damage to the corrugated cardboard Crushing, using shallow pressure without forming, and secondary indentation in the process, resulting in low turnover efficiency of corrugated cardboard, cumbersome production process, low production efficiency, and serious waste of manpower and resources
