Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a printing paper feeding mechanism. Background Art

[0002] Paper, also known as matte felt paper, is made from raw materials containing plant fibers through pulping, modulation, papermaking, processing and other process flows. It can be used for writing and painting, printing books and newspapers, packaging, etc. Unlike paper, which is the "silk residue" of animal fibers, it can be folded into sheets for writing. Paper is a carrier for writing and printing, and can also be used for packaging, hygiene and other purposes, such as printing paper, carbon paper, toilet paper, facial tissue, etc. The invention and promotion of paper has enabled humans to no longer use mud, stone, wood, pottery, metal and other materials to record text or pictures, and has also enabled a large amount of information in ancient times to be disseminated and preserved.

[0003] The Chinese patent document with publication number CN208440015U discloses a printing paper feeding mechanism, which can absorb and convey paper through the air holes on the conveying roller. When the air holes absorb the paper, the paper is evenly stressed, thus avoiding the problem of paper damage caused by excessive local stress during the paper conveying process.

[0004] However, since the structure of the paper placing device of this device is too simple, the staff needs to manually press down the elastic component before placing the material into the storage slot, which makes the placement work too complicated. In addition, since the elastic component needs to be retracted and extended for a long time, it is often more prone to wear than general transmission devices, and thus needs to be improved.
