Comparing positive pressure and negative pressure Single facer machine, the difference is 1: The adsorption type single facer machine mainly solves the problem of paper adsorption. After the paper enters the corrugating roller, the corrugating roller rotates at a high speed, which will generate an outward centrifugal force, which is very It is easy to throw out the corrugated paper, so the corrugated is not easy to form. Therefore, the principle of the equipment is to firmly adsorb the corrugated paper on the corrugated roller.

The negative pressure Single facer machine is to use negative pressure to adsorb the corrugated paper on the corrugated roller, which is divided into two types: internal suction and external suction. The positive pressure is to blow the paper on the corrugating roller through the wind, so one is sucking and the other is blowing.
In the case of negative pressure, the paper of the Single facer machine is firmly adsorbed on the corrugating roller by suction. When the corrugating roller rotates, the corrugated paper needs to be separated from the corrugating roller, which requires a copper knife to peel it off the corrugating roller. When the copper knife is inserted, it will form a very regular strip, which has an impact on the strength of the corrugated paper, so in the case of the negative pressure adsorption corrugated roller, the matching between the copper knife and the suction is very important.
Through the above introduction and analysis of the Negative pressure Single facer machine, hope it helps you.
