Single-sided machine - There is dirt on the paste roller and the gap between the top roller and the bottom corrugated roller is too large
The following illustration illustrates the two issues mentioned in the title. There is dirt on the paste roller, so the glue cannot be transferred smoothly.
This result can be seen in the blank space of the paste line. There is only a small amount of paste glued on the paste roller, and it will be wiped off. This will lead to insufficient glue on the dome during gluing. This will result in intermittent droplets we see in the photo. Paste glue. When the gap between the upper and lower corrugating rolls is too wide, the upper roll cannot contact the lower corrugated roll and there is not enough paste on the top of the core paper corrugation. In addition, it should be noted that the uneven condition of the paste line indicates that the pressure applied when extruding the starch paste is insufficient, and no standard “rail” shape is formed. The paste strength of the paper after bonding the paste shape, The carton compressive strength and adhesion are reduced.
