ABSTRACT:
An improved photo coating machine of the present disclosure is used to put an evenly distributed coating of chemical fluid on the surface of a photograph so as to form a protective film thereon. The photo coating machine is equipped with a roller assembly, a driving mechanism, a coating device, a drying device, a micro adjustment mechanism, and an adjustment mechanism and a mounting base. The rollers of the roller assembly are disposed with each other in rotational abutment but not in linear alignment. Coating chemical fluid is sprayed between two of the rollers that evenly distribute the chemical fluid upon the surface of a photo that is fed between the rollers. Each roller of the roller assembly is provided with a peripheral groove at each end thereof for the collection of excess chemical fluid on the rollers which is recycled to the coating device so as to prevent the mounting base from contamination. The micro adjustment and the adjustment mechanisms are responsible for varying the space between each pair of the rollers so that photos of different sizes can be fitted therebetween.
