Technical Field
[0001] The utility model belongs to the technical field of rotary printing presses, in particular to a rotary printing press with a folding structure. Background Art
[0002] A rotary printing press, also known as a web printing press, is a high-speed printing device that uses roll paper. Compared with traditional sheetfed printing presses, a rotary printing press prints on continuous roll paper, greatly improving production efficiency. It is suitable for high-speed printing of large quantities of newspapers, magazines, books, advertising leaflets, etc. A rotary printing press usually includes multiple continuous production links such as paper feeding, printing, drying, folding, and collecting, which can realize automated assembly line production from paper rolls to finished products. A rotary printing press with a folding structure is a device that can fold paper directly inside the machine after the printing process is completed. This integrated printing and folding system greatly simplifies the production process, reduces intermediate processing links, and improves production efficiency and the continuity of paper processing.
[0003] The existing rotary printing machine with a folding structure conveys the printed paper between two folding rollers, and then folds the paper by cooperating with the rotating folding rollers through a downward-moving pressure plate. It lacks a limit and anti-deviation mechanism for the paper when folding. The paper is prone to lateral or longitudinal deviation during the conveying and folding process, resulting in inaccurate folding position, affecting the appearance and quality of the finished product. Paper deviation may cause folding failure, requiring shutdown adjustment or manual correction, increasing the scrap rate and reducing production efficiency. Utility Model Content
[0004] In view of this, the present invention addresses the deficiencies of the existing technology and provides a rotary printing press with a folding structure. The position limiting and anti-deviation mechanism can automatically adjust to accurately position papers of different sizes during the folding process, improve the accuracy and consistency of folding, ensure the quality of the finished product, and at the same time reduce the downtime adjustment time caused by paper deviation, thereby improving overall production efficiency.
