1. Glue on the edge of the paper
Analysis of the reasons: ①The belt of the rubber coating roller is not in place; ②The rubber disc is vibrated and free; ③The temperature at both ends of the single-sided machine tile roller is insufficient or too high. After the corrugated glue is applied immediately, the low temperature makes the glue not gelatinized, and the water quickly penetrates into the corrugated paper to leave a starch mark. After the high temperature corrugated glue is applied, the glue quickly loses its viscosity.
Solution: ① Open the glue valve properly to increase the flow of glue; ② Correct the fixed rubber plate; ③ Raise the temperature of the corrugating roller, and dip your finger in water to bounce it on the corrugated roller, and the water droplets should evaporate within two or three seconds. . If the temperature is too high, the two ends of the corrugated roller can be smeared with a brush and oil, and the evaporated oil fume will take away part of the corrugated heat, which can achieve the purpose of cooling.
2. The edge of the face paper is glued
Analysis of the reasons: ① the glue roller is not in place; ② the conveyor belt of the dryer is deviated, and the edge of the cardboard is not pressed in place; ③ the temperature of the hot plates on both sides of the dryer is insufficient.
Solution: ① Fill up the glue in the plastic box, so that all the glue rollers are immersed in the glue; ② Correct the deviation in time to make the conveyor belt in place correctly; ③ Wait until the temperature of the dryer hot plate is stable and then start the machine
