[0059] The solid raw material in the heating box 2 is heated by the electric heating tube 29.

The rubbing force between the smearing roller 11 and the optical film makes the smearing roller 11 rotate. The smearing roller 11 dips the raw material in the dipping frame 9, and then rotates to contact and smear the raw material on the optical film when the smearing roller 11 rotates to contact the optical film, thus completing the smearing work.

[0060] Due to the limiting of the adjusting guide rod 27, the rotating adjusting screw rod 25 makes the scraper 26 descend, the gap between the scraper 26 and the optical film is changed, thus the thickness of the raw material smearing is changed. The drying air pump 133 is started to make the hot air in the heating box 2 sequentially pass through the drying communication tube 132, the drying connecting tube 134, the drying main tube 135 and the drying air nozzle 136 to spray out, thus accelerating the drying of the raw material.

[0061] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
