The utility model also provides a printing press plate roller structure, which comprises: the outer surface of the inner roller is fixedly connected with four clamping blocks which are circumferentially distributed at intervals; the surface of annular connecting piece has seted up first screw hole, annular connecting piece with interior roller threaded connection, annular connecting piece is located the side of fixture block.

The annular connecting piece that the interior roller cooperation that sets up through setting up uses, simple structure, the dismouting of being convenient for, and fixture block fixed connection is including the surface of roller, convenient maintenance, and life is longer.

According to the printing press plate roller structure, the outer surface of the inner roller is clamped and connected with the outer roller, four clamping grooves which are circumferentially distributed at intervals are formed in the inner wall of the outer roller, and the clamping blocks are clamped and connected in the clamping grooves.

The clamping grooves arranged in the outer roller are matched with the clamping blocks arranged on the inner roller, so that the connection and fixation of the inner roller body and the outer roller can be reinforced.

According to the printing roller structure of the printing machine, the second threaded holes are formed in the surfaces of the two sides of the outer roller, and the annular connecting piece is detachably connected with the outer roller through bolts.

The inner roller and the outer roller are fixedly connected through the annular connecting piece, and the connection is stable and convenient to disassemble and assemble.

According to the printing press plate roller structure, the inner wall of the inner roller is fixedly connected with the shaft roller. The shaft roller is used for supporting the inner roller and the outer roller which are fixedly arranged.

According to the printing press plate roller structure, the outer surface of the shaft roller is fixedly connected with the connecting shaft, and the connecting shaft is positioned at the side of the inner roller. The connecting shaft is used for connecting and fixing the shaft roller and the external structure.

Additional aspects and advantages of the utility model will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model.
