AI Technical Summary
Existing coating machines are prone to uneven coating when applying soft materials, especially when double-sided coating requires double operation, resulting in low efficiency.
A bidirectional spray head is used in conjunction with a leveling roller and a hot air drying box. After being evenly coated by the spray head, it is compacted by a leveling roller and then quickly dried in a hot air drying box to ensure uniform coating.
It achieves efficient and uniform coating of soft materials, reduces operation steps and improves production efficiency.
