Description

Technical Field

[0001] The utility model relates to the technical field of wheel hinges, in particular to a wheel hinge folding structure. Background Art

[0002] A folding paper structure is one that unfolds when in use and folds away when not. This structural form is not only widely used in architecture, such as in foldable, mobile theaters, but also plays an important role in a variety of fields, including aerospace, civil engineering, and biomedicine. The advantages of folding structures include reusability, a small size when folded, and ease of transportation and storage. Compared to permanent structures, folding structures are more time- and labor-efficient to construct, avoiding the waste caused by unnecessary reinvestment. Furthermore, the design and calculation theory and structural forms of folding structures have made significant progress in recent decades, moving beyond the laboratory and finding widespread engineering application.

[0003] Folding structures are categorized into inward fold, outward fold, and center fold. These categorizations are based on the structural requirements of the paperboard. For example, after a paper box is folded, if the bottom layer of the paperboard is at the two inner corners of the box (box), and the top layer is at the two outer corners of the box (box), it is an inward fold; otherwise, it is an outward fold. If the paperboard is folded 180 degrees, with the two bottom layers facing each other, it is an inward center fold; otherwise, it is an outward center fold.

[0004] At present, in the actual application process of the wheel-type leaf folding structure, the paper is folded by conveying it into the folding mechanism. After the folding is completed, the folding mechanism is used to complete the folding of the paper. However, when the folding mechanism folds the paper, if the folding plate descends at a high speed or the friction between the paper and the bottom plate is large, the paper will be damaged during the folding process, which is not conducive to the subsequent work.
