AI Technical Summary
When using flat cores in existing coating machines, the cores tend to climb up the conical surface inside the drum, end up on the drum flange, and get stuck, resulting in ineffective coating.
Components such as stops, diagonal bars, support rods, and deflectors are installed at the sun gate of the coating machine. The stops are used to pull the core back into the drum, and the deflectors and flexible tubes are used to blow the core to prevent it from getting stuck.
It effectively prevents core residue, improves coating efficiency, reduces material leakage, and ensures smooth core coating.
