Automatic sheet article folding mechanism

Abstract

The invention discloses an automatic sheet article folding mechanism. The automatic sheet article folding mechanism comprises a sheet article storage unit, a sheet article taking unit for obtaining and transferring sheet articles, a first paper folding unit for conducting primary folding on the sheet articles, a conveying unit for conveying the sheet articles subjected to the primary folding and a second paper folding unit for conducting secondary folding on the sheet articles, wherein the first paper folding unit comprises two first shaft rollers arranged in parallel in an reserved gap mode and a first paper pressing knife arranged above the gap between the two first shaft rollers and capable of performing lifting motion, the second paper folding unit comprises two second shaft rollers arranged in parallel in an reserved gap mode and a second paper pressing knife arranged above the gap between the two second shaft rollers and capable of performing lifting motion, and the first shaft rollers are mutually perpendicular to the second shaft rollers in axial direction. Two-time mutually-perpendicular folding can be conveniently and successively conducted on the sheet articles by vertically setting the axial directions of the two groups of shaft rollers, the sheet articles can be pre-bent through the paper pressing knives and then are folded under the driving of the shaft rollers.

Description

Technical field [0001] The invention relates to the technical field of sheet article folding, in particular to an automatic folding mechanism for sheet articles. Background technique [0002] At present, in the process of product packaging, paper documents such as manuals and manuals are usually loaded together. The manuals and manuals are often printed on larger sheets of paper, and usually need to be folded before they can be loaded for packaging. Inside the box and the shell. In production lines with a relatively high level of automation, there are already automatic folding mechanisms to fold paper. For example, the Chinese Utility Model Patent No. ZL 200720117934.9 discloses an automatic folding machine that uses multiple pairs of rolls to cooperate to achieve various shapes. However, this type of existing automatic paper folding machine can only realize multiple parallel paper folding processes, but cannot realize mutually perpendicular "cross" folding. Summary of the inve...

In production lines with a relatively high level of automation, there are already automatic folding mechanisms to fold paper. For example, Chinese Utility Model Patent No. ZL 200720117934.9 discloses an automatic paper folding machine, which uses multiple pairs of rollers to cooperate to achieve various shapes. However, this existing automatic origami machine can only realize multiple parallel origami processes, but cannot realize the folding of mutually perpendicular "cross" shapes
