The installation structure of a mold encoders includes a die cutting roll, a frame and an encoder. The die cutting roller is connected with the encoder through the intermediate shaft. The die cutting roll includes the roll body and the roll shaft on the side of the roll body. The end center of the roller shaft is a concave hole. The encoder includes the encoder seat and the bearing core shaft, and the intermediate shaft includes the step surface, the pressing face and the rod. The connecting end of the encoder and the encoder; the step surface of the intermediate shaft is matched with the concave hole in the center of the roll shaft of the die cutting roller, and press the pressure plate to compress the compression surface of the intermediate shaft. The connecting end of the rod and encoder is penetrated from the center of the press disc; the end of the encoder connection is inserted into the encoder seat and connected with the bearing core shaft. Through the installation structure of the mold encoder provided by the utility model, the intermediate shaft and the roller shaft are pressed tightly by the press disc, which ensures that the intermediate shaft does not beat during the operation, and adjusts the concentricity of the intermediate shaft and the roll shaft in the installation, and then there is no need to be calibrated again.
