AI Technical Summary
The existing folding mechanism lacks an adaptive adjustment structure, which causes the edge position of the paper to shift when it enters, affecting the folding accuracy.
The structure employs a support plate, limiting rod, and pulley. The limiting rod and limiting hole work together to allow the pulley to slide freely and press against the edge of the paper. At the same time, the waist-shaped hole and screw nut are used to adjust the position of the folding knife to ensure that the edge of the paper is flat and the center of the folding knife is aligned with the center of the paper.
This design ensures that the paper is aligned at the edges and has a flat surface when it enters the folding mechanism, improving the precision and accuracy of folding. It also ensures that the center of the folding blade is aligned with the center of the paper, enhancing the neatness of the folds and ease of use.
