Description

Technical Field

[0001] The invention relates to the technical field of corrugated machines, in particular to a non-indentation wind-blown press-type single-face corrugated machine. Background Art

[0002] The process flow of the finished cardboard product is as follows: the corrugated base paper is preheated by the corrugated paper preheating cylinder, and then pressurized and heat-transferred by the upper and lower corrugated rollers to form a corrugated shape. The corrugated tip formed by the press is contacted with the glue roller and glued. Then, the inner paper preheated by the inner paper preheating cylinder is bonded to the inner paper with the glued corrugated paper by adding wind pressure through the wind pressure module.

[0003] The traditional single-sided corrugated machine is a pair of corrugated rollers and a pressure roller. The corrugated paper after pressurization and heat transfer by the corrugated roller is glued by the gluing roller and bonded to the inner paper after pressurization by the pressure roller. The problems that are prone to occur in this traditional mode are as follows: During the contact process, sometimes the inner paper contacts the top of the corrugated paper, and sometimes contacts the flute of the corrugated paper, causing the pressure roller to form periodic changes with the center of the upper corrugated roller. The more flutes there are, the higher the frequency of change; the larger the flute type, the greater the frequency of vibration; the faster the vehicle speed, the higher the frequency of vibration, resulting in large resonance and noise of the single-sided machine, affecting the compressive strength and aesthetics of the cardboard, and poor cardboard quality. Although the traditional belt-pressed corrugated machine produces products without rib patterns and good strength, its belt is a wearing part with a short life and poor durability, and the replacement and maintenance costs are high.

[0007] The beneficial effects of the present invention are as follows: during processing, the heating box heats the wind and sends it to the wind outlet box through the guide pipe, and the high-pressure hot wind is blown onto the inner paper through multiple nozzles, so that the inner paper and the corrugated paper are perfectly bonded, and the processing quality is better. The present invention pressurizes the inner paper through the wind blowing pressure mode so that the inner paper and the corrugated paper with glue are perfectly soft-bonded, ensuring the quality of corrugated paper processing; moreover, it has a compact structure, reasonable design, and convenient maintenance.
