The utility model relates to the technical field of paint surface detection, in particular to a friction roller and a friction assembly structure for a paint surface wear experiment. The friction roller for the paint surface wear experiment comprises a friction belt and a roller core, the roller core is of a cylindrical structure and forms a rotating center of the friction roller; a friction belt is fixed and wound on the roller core, and the wound friction belt and the roller core form a cylindrical structure with a friction layer on the side face to form the friction roller.

This invention provides a method for controlling constant tension on a wrapping reel and a wrapping reel with a constant tension control mechanism. The constant tension is controlled using a mechanical structure, which is simple and ingenious, requiring no complex electrical control components. When the wrapping reel is fully loaded with insulating tape, a cam lifts the adjusting rod. As the wrapping progresses, the diameter of the reel gradually decreases, and the pressure roller moves closer to the inside of the reel, causing a swing arm to oscillate. The cam at the other end of the swing arm rotates with the swing arm, causing the adjusting rod to rotate as well. Because the adjusting rod rotates eccentrically, and the longer side of the adjusting rod is closer to the friction wheel, the friction tape is loosened with a larger vertical displacement; the shorter side of the adjusting rod is farther from the friction wheel, tightening the friction tape with a smaller vertical displacement. Overall, the friction tape is loosened, thus reducing the clamping friction torque. This achieves constant tension as the wrapping reel gradually reduces the amount of tape being wrapped.
