[0002] A rotary printing machine is a machine that can print on the surface of some materials such as paper, so that some patterns can be printed on the surface of these materials, which is convenient for later sales or processing. After the existing rotary printing machine prints the material, a receiving roller is set at the tail end of the printing equipment to wind and collect the printed material, resulting in a large weight after the receiving roller collects the material, which is inconvenient to carry and unload. For this reason, we propose a unloading mechanism for a rotary printing machine. Utility Model Content

[0006] Preferably, a sliding piece is provided inside the connecting box, and a limiting tooth for limiting the driving gear is installed on one side of the sliding piece. A screw groove is provided on one side of the connecting box, and a screw shaft is connected to the internal thread of the screw groove. A connecting groove is provided on one side of the sliding piece, and one end of the screw shaft is rotatably connected to the inner side of the connecting groove.

[0007] Preferably, when the screw shaft is rotated, the sliding piece inside the connecting box drives the limiting teeth to approach the meshing limiting state with the driving gear.

[0008] Preferably, supporting teeth are installed on the other side of the pressing arm, and a rotatably matched supporting gear is provided inside the inner side of the storage cavity through the connecting piece, and the supporting gear meshes with the supporting teeth on one side of the pressing arm.

[0010] Beneficial Effects

[0011] The utility model provides a feeding mechanism for a rotary printing machine, which has the following beneficial effects:

[0012] 1. A material unloading mechanism for a printing rotary machine. In this article, after the receiving roller completes the winding of the printing material, the control shaft can be rotated by rotating the rocker, and the driving gear inside the connecting box will rotate under the control of the control shaft to engage and drive the driving teeth on one side of the top pressure arm to drive the top pressure arm to move up and down. At this time, the top pressure arm can support and lift the receiving roller when it moves upward, and when the screw shaft is rotated, the limit teeth on one side of the slide can be driven horizontally and the driving gear can be engaged and limited to ensure the support stability of the top pressure arm. At this time, the movable arm can be located outside the support arm and slid out through the sliding of the lever, and then the descent of the top pressure arm can be controlled again to make the two ends of the receiving roller dock with the external shipping support equipment, thereby achieving the effect of facilitating the external winding material of the receiving roller to be conveniently removed for unloading and use.
