Abstract

The invention discloses a dismounting device for a hexagon nut of a paper feeding machine. The dismounting device comprises a threaded stud. The outer surface of the threaded stud is provided with an external screw thread. The end portion of the threaded stud is provided with an unloading cylinder. The inner surface of the unloading cylinder is provided with an internal thread groove. The threaded stud is in sleeve joint with a sleeve disk. The threaded stud is inserted with a connecting rod, the end portion of which is provided with a conical ring. The outer surface of the conical ring is in sleeve joint with a surface bearing.The dismounting device for the hexagon nut of the paper feeding machine has following beneficial effects: due to the fact that the hexagon nut can be installed in a sleeving mode by means of the internal thread groove of the unloading cylinder, the hexagon nut of the paper feeding machine can be conveniently unloaded for facilitating assembly of the paper feeding machine; and by means of the surface bearing, butt joint of a rotary shaft is conveniently carried out, thereby dismounting the hexagon nut in an automated mode.

Description

technical field [0001] The invention relates to a loosening device, in particular to a hex nut loosening device for a paper feeding machine. Background technique [0002] Paper feeder, commonly known as feeder, is a very important part of modern offset printing machines. Its function is to automatically, accurately and steadily send paper to positioning or printing devices according to certain rules. The hex nuts on the existing paper feeder are inconvenient to loosen and unload, and it is inconvenient to assemble the paper feeder mechanism, which will greatly affect the maintenance of the paper feeder. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a hexagonal nut that can be set in the internal thread groove of the loosening cylinder, so as to facilitate the loosening and unloading of the hexagonal nut on the paper feeder, and facilitate the installation of the paper feeder mecha...
