[0002] A folding machine is an automated device specifically designed to fold materials (such as paper, plastic sheets, etc.) along predetermined creases. It is widely used in printing and packaging, stationery production, electronics industry, and advertising production to efficiently and neatly achieve various folding methods.
[0003] However, traditional folding mechanisms typically employ semi-automatic or manual operation, lacking automation capabilities and having long operation cycles, resulting in reduced production efficiency. Furthermore, folding quality can fluctuate under different material or environmental conditions, affecting product consistency.
[0004] Therefore, those skilled in the art have provided a folding mechanism for a folding machine that provides precise folding, in order to solve the problems mentioned in the background art. Utility Model Content
