Comma Coater

Comma coater is composed of unwinding, traction, corona, dust removal, comma scraper coating head, oven, rectification, second unwinding and stripping winding, compounding, storage, winding, heating, air duct and control system, among which the coating head and oven runner are the core technologies. The working principle of the equipment is that the coiled PETG or TPU substrate is conveyed by the unwinding unit, and then enters the comma transfer coating head unit through traction, corona, dust removal and other devices, wherein the function of the coating head is to uniformly coat the slurry on the surface of the substrate. The principle is that the slurry is metered and transferred to the coating roller by adjusting the gap between the coating roller and the comma scraper, and then by adjusting the gap between the back roller and the coating roller, The slurry measured on the coating roller is transferred to the surface of the substrate, and then enters the oven for drying. At the outlet of the oven, the dried material is corrected, and then a protective film stripped by the second unwinding is attached by a large-diameter roller and a rubber pressing roller, and finally the finished product is rolled.
