Structure and principle of coating equipment
The main components of coating equipment include: unwinding, head, heating system and winding mechanism.
The coating operation is to evenly coat the slurry in the trough on the surface of the substrate through the coating roller, and then transfer it to the winding end after drying in the oven.
In the whole process of coating operation, the speed of the substrate and the speed ratio of the coating roller and the back roller are controlled by the tension induction system of unwinding, driving and winding.

 

The factors that affect the coating quality of coating equipment are as follows:
