Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without any creative work based on the embodiments of the present invention belong to the protection scope of the present invention.

Example one

Referring to the drawings, the present invention provides a technical solution: the paper pressing wheel swing rod lengthening device of the double-jaw collating machine comprises a roller 1, wherein a first rotating shaft 2 is fixedly arranged at the axis of the roller 1, a second rotating shaft 3 is rotatably connected inside the roller 1, and a jaw 4 is fixedly arranged on the surface of the second rotating shaft 3;

a swing rod 5 is arranged on the left side of the roller 1, a pressing wheel 6 is rotatably connected below the front side of the swing rod 5, and the surface of the pressing wheel 6 is in rolling connection with the surface of the roller 1;
