[0001] The utility model relates to the technical field of folding machines, in particular to a folding machine with multi-mode switching and precise positioning. Background Art

[0002] A folding machine is a device used to fold printed paper according to specific requirements. Folders are widely used in the printing industry, such as the production of books, magazines, brochures, leaflets and other printed materials. With the development of technology, the functions of existing folding machines are becoming more and more abundant. Some multi-mode folding machines can achieve multiple folding styles such as half fold, tri-fold, accordion fold, cross fold, etc. to meet the needs of different printed materials.

[0003] In the existing operating mechanism of the folding machine, a press wheel is usually used at the end to press the cardboard pulled out by the conveyor belt. Specifically, these press wheels are placed on a rotating rod. However, when switching between different modes, the folded cardboard has different lengths, which causes the position of the press wheel on the rod to change accordingly. At present, each position adjustment must be done manually to adjust the position of the press wheel, which greatly reduces the degree of automation of the entire device. Therefore, it is necessary to design a folding machine with multi-mode switching and precise positioning to solve the above problems. Utility Model Content
