Abstract
A method of manufacturing a rolling shaft of a photo printer mainly has two rubber casings sleeved at two ends of a long cylindrical rod which is then placed horizontally; after that, the long cylindrical rod is sprayed with a layer of resin thereby forming an rubber wheel at the central position of the long cylindrical rod; finally, the rubber wheel is adhered with a layer of fine grain material with high coefficient of abrasion such that the rolling shaft has a preferred abrasiveness and causes no chemical reaction with the photo paper.
Claims1
A method of manufacturing the rolling shaft of a photo printer comprising steps of:
- (a) sleeveing rubber casings at two ends of a long cylindrical rod;
- (b) spraying a layer of thin film of resin onto the long cylindrical rod thereby forming a rubber wheel at the central position of the long cylindrical rod;
- (c) adhereing a layer of abrasion resistance fine grain material on the rubber wheel surface of the long cylindrical rod;
- (d) spraying a layer of thin film of resin onto the surface of the long cylindrical rod adhered with fine grain material;
- after the sprayed resin dries out, the two rubber casings are removed to finish manufacturing the rolling shaft.
