Abstract
Description
Technical Field
[0001] The utility model relates to binding equipment, in particular to a folding mechanism of a binding machine. Background Art
[0002] A binding machine is a device that can bind paper into books. One type of paper has text and patterns printed on a long sheet of paper after printing. Before binding, the paper needs to be folded by a folding mechanism and then sent to the binding assembly for binding. The traditional folding mechanism mainly includes two folding rollers that are arranged in a coordinated manner. A folding push plate is arranged below the folding roller. When working, the paper is conveyed between the folding roller and the folding push plate. The folding push plate rises and drives the paper into the space between the two folding rollers, thereby realizing the folding of the paper. The rotation speed of the two folding rollers is fixed, but in actual use, there are certain differences in the folding time and subsequent binding time required for different papers. It is easy for the two groups of paper to be too far apart or the two groups of paper to collide after folding, which affects the processing quality and efficiency; in addition, due to the difference in thickness of different types of paper, the effect of folding the paper when passing through the folding roller is also different, and the folding quality is difficult to guarantee.
