Thick film coating device

Abstract

The utility model relates to the technical field of coating, and discloses a thick film coating device which comprises a coating machine, a curtain type coating die head is arranged on the coating machine, and a hot air cover for blowing hot air to the curtain type coating die head to reduce the temperature difference between the curtain type coating die head and the environment is sleeved on the outer side of the curtain type coating die head; the hot air cover comprises two cover plates located on the side face of the curtain type coating die head and provided with hot air pipes, two plugs blocking the two cover plates and a plurality of installation panels connecting the two cover plates and the curtain type coating die head, and the hot air pipes are located on the inner sides of the cover plates and used for guiding hot air into hot air channels formed by the cover plates and the outer side face of the curtain type coating die head. The hot air can help maintain the temperature of the surface of the coating die head, and water mist condensation caused by temperature difference is reduced, so that the coating quality is improved. Water mist condensation caused by temperature difference is reduced through hot air heating, and corrosion and abrasion of the wall face of the coating head are prevented.
