Description

Technical Field

[0001] This utility model relates to the field of printing press technology, specifically to a printing press feeding mechanism. Background Technology

[0002] A printing press is a machine used to print text and images. According to the type of printing plate, it can be divided into letterpress, offset, gravure, and screen printing presses. According to the form of paper used for printing, it can be divided into sheet-fed printing presses and web printing presses. Its working principle is basically to transfer the ink of the image area on the printing plate to the substrate. With the development of technology, modern printing presses have a high degree of automation and can achieve high-speed and high-precision printing. They are widely used in publishing, packaging, advertising and many other industries. In addition, in order to facilitate the quick collection of printed products, a feeding mechanism is often used, which can facilitate automatic printing and improve production efficiency.

[0003] Chinese Utility Model Patent Publication No. CN 221234931 U discloses a feeding mechanism for a digital printing machine. This feeding mechanism, by incorporating a fan, a heating device, and a cooling pipe, uses a control switch to rotate the fan, pushing the heat generated by the heating device onto a conveyor belt to dry the items being transported on the belt. This effectively dries the freshly printed ink, preventing ink smudging. After heating and drying, the cooling pipe further cools the items, allowing them to be directly handled and used, thus improving the device's efficiency. However, while this feeding mechanism achieves the drying effect, it is difficult to tension the conveyor belt during feeding, resulting in poor conveying efficiency. Furthermore, it is not easily adjustable according to the width of the printed material, limiting the versatility and application scenarios of the feeding mechanism. Summary of the Invention
