Pushing structure for transferring manipulator for printer rubber covered roller

The utility model discloses a pushing structure for transferring a manipulator for a printer rubber covered roller, which comprises pushing mechanisms, a loading and unloading tool arranged on the pushing mechanisms and a charging tray placed on the loading and unloading tool, the pushing mechanisms are symmetrically distributed on two sides of the charging tray, each pushing mechanism comprises four pushing rods, and the four pushing rods are symmetrically arranged on the two sides of the charging tray. Positioning sleeves are fixed to the front ends of the push rods and correspond to the V-shaped grooves in the material disc one to one. According to the utility model, the push rods on the two sides of the tool are respectively and correspondingly placed at the two ends of the rubber roller in the charging tray, so that the push rods push the positioning sleeves to be sleeved outside the two ends of the rubber roller through the pushing of the air cylinder when the clamping jaw grabs the rubber roller, the r
