Description

Technical Field

[0001] The utility model belongs to the technical field of papermaking, and in particular relates to a paper sheet finishing device. Background Art

[0002] Calender is a key equipment that determines the quality index of paper. It is mainly composed of hard roller and soft roller. During operation, the paper sheet contacts with the hot roller. In a short time, the hot roller transfers heat energy to the paper and penetrates to a certain critical depth. At this time, the temperature of the paper surface reaches or approaches the glass softening point. At this time, the plasticity of the paper surface is strengthened, and the soft roller is elastically deformed when under pressure, and the pressure zone forms a surface contact. The mirror-like hard roller makes the capsuled paper surface smooth and shiny, and retains a good thickness.

[0003] However, the existing public document CN219410342U papermaking soft calender, under the water supply of the water supply mechanism, sprays the water in the water tank on the surface of the paper through the nozzle, thereby increasing the moisture content of the paper. Under the action of the moisture, the heat energy of the pressing roller can quickly enter the inside of the paper, realizing rapid heat transfer, so as to reduce the yield strength of the paper and improve the plasticity of the paper, thereby increasing the smoothness and glossiness of the paper after the calender processing, and further improving the calendering effect of the paper. However, whether the paper can be guaranteed to be flat after passing through the calender for the first time requires manual observation, and cannot be monitored in real time, and cannot be handled in time when unevenness is found.
