The web paper mounting machine is composed of paper feeding mechanism, paper mounting mechanism and paper pressing mechanism. Two wind heads are arranged on the paper feeding mechanism side by side, and an intermediate positioning mechanism is arranged on the paper mounting mechanism. The paper mounting mechanism is divided into two paper paths, and wing spring plates are arranged on both sides of the paper mounting mechanism. The intermediate positioning mechanism is composed of an intermediate positioning guide block and a lifting mechanism, which is a widely used paper mounting machine Used for food, wine, household appliances, light industry and textile products packaging equipment.

　　When some users use the paper mounting machine, they will encounter the phenomenon of paper take-up, so what causes it?

　　When the paper enters the pressing part, the glue between the base paper and the face paper is not in a dry state, and the friction between the base paper and the face paper is not enough to overcome the shearing force they are subjected to. And the thicker the paper, the greater the shear force, the more prone to "take up" phenomenon.

　　Through the analysis of the "paper take-up" phenomenon in the pressing part, the optimization design model can be established. Through the model calculation, the reasonable distribution of roller distance can effectively control the "paper take-up" phenomenon in the pressing part.

　　In the daily production, because of the inaccuracy of the connection of the teeth in each group during the printing of the face paper, the tear phenomenon appears in the mouth of the face paper. When mounting with paper mounting machine, it is easy to bump the face paper into bending or folding state in the process of paper feeding. After mounting, the face paper and corrugated board will not be aligned. When this happens, we should adjust the handover time of the teeth to prevent tearing the edge of the face paper.
