Abstract

The invention discloses a double-roller thermal printing equipment, which relates to the technical field of film material processing, including a processing rack, a lower roller is fixedly installed on the inner cavity wall of the processing rack, a heating device is fixedly installed on the surface of the lower roller, and the lower roller is fixed on the surface of the lower roller. Above the roller is an upper roller that can move up and down and rotate at the same speed as the lower roller. The upper roller drives the upper roller to move up and down through the power mechanism, and the lower roller and the upper roller pass through the cathode rotation. Printing film, proton exchange film, anode transfer film, the cathode transfer film and the anode transfer film are made by the extrusion between the lower roller and the upper roller and the heating action of the heating device. The material on the upper surface is attached to the surface of the proton exchange membrane. The present invention squeezes the material through the contact between the lower roller and the upper roller. Since the contact surface between the upper roller and the lower roller is small, the material can be prevented from passing through. When the extrusion and heating device heats it, wrinkles appear, which improves the yield of the product.
