Technical Field

[0001] The utility model relates to the field of printing, in particular to a cardboard raw material feeding mechanism for a chain type printing press. Background Art

[0002] A chain press is a mechanical device used for printing that uses a chain drive system to transfer printed materials. This type of press is often used for large-scale printing tasks, such as the printing of books, newspapers, and magazines. Chain presses usually have high-speed production capabilities and automation features, making them one of the most important equipment in large-scale printing production.

[0003] However, there are still some shortcomings in this patent.
