Abstract
This utility model discloses a coating head device for special paper processing, specifically relating to the field of special paper coating technology. It includes a coating top mold, a coating bottom mold located on the outer side of the lower end of the top mold, and a concave liquid storage tank on one side of the upper end of the bottom mold. Multiple limiting slots are also provided on the upper end of the bottom mold near the concave liquid outlet tank. In practical use, by aligning the limiting slots, adjusting plate, and limiting blocks, the limiting blocks can be easily installed inside the limiting slots, thereby locking the adjusting plate inside the concave liquid storage tank. This makes installation and removal of the adjusting plate more convenient. Simultaneously, the inclined surface at the lower end of the adjusting plate changes the direction of the coating liquid inflow, and also better expels excess air from the concave liquid outlet tank when the coating liquid level rises, preventing air from mixing into the coating liquid. This results in a more uniform coating process for special paper.
