AI Technical Summary
Technical Problem
In existing technologies, ultrasonic spray humidification methods suffer from large and uneven atomized particles, poor penetration, high noise, and high water quality requirements, making it difficult to meet the uniform humidification requirements of cured filter paper.
Method used
A steam rehumidification device is used to permeate the filter paper with small and uniform steam particles. Combined with an online NIR moisture analyzer for non-contact detection, the humidity of the filter paper can be precisely controlled.
Benefits of technology
To ensure uniform filter paper humidity, reduce noise pollution, improve production efficiency, and achieve precise control of filter paper humidity and stable product quality.

Abstract
This utility model discloses a rewetting device for a cured filter paper production line, comprising: a frame; three sets of rollers for supporting the cured filter paper rotatably installed within the frame; a rewetting mechanism for rewetting the filter paper, located on the frame and between the first two sets of rollers in the filter paper conveying direction, the rewetting mechanism including a cover that sprays steam from the bottom of the filter paper to rewet it; and a detection mechanism for detecting the moisture content of the filter paper, located on the frame and between the last two sets of rollers in the filter paper conveying direction, the detection mechanism including an online NIR moisture analyzer that performs non-contact moisture detection on the filter paper from above. By using steam rewetting instead of ultrasonic spraying, the steam particles are small and uniform, allowing for rapid penetration into the cured filter paper, overcoming the problems of large atomized particles and poor penetration, ensuring uniform filter paper humidity, and providing a good performance foundation for subsequent winding and other processes.
