The conveying mechanism includes a first synchronous wheel, a second synchronous wheel, a first synchronous belt, a connecting rod, a gear and a pressure roller. The utility model sets a first synchronous wheel and a second synchronous wheel, and the third synchronous wheel and the fourth synchronous wheel drive the first synchronous wheel and the second synchronous wheel to rotate when the third synchronous wheel and the fourth synchronous wheel rotate.
