Description

Technical Field

[0001] The present invention relates to the field of printing technology, and in particular to a roll-to-flatbed printer. Background Art

[0002] A roll-to-flatbed printer is a multifunctional printer capable of printing on both flatbed and roll materials. It typically includes a printing mechanism, a flatbed feed mechanism, and a roll feed mechanism. To prevent interference between flatbed and roll materials, roll-to-flatbed printers place the flatbed and roll feed mechanisms at opposite ends of the printer. This allows printing on either roll material or flatbed material by simply activating the feed mechanism.

[0003] The Chinese utility model patent number CN219988825U discloses a roll-to-flat printer that uses a cutting assembly on the printer to automatically cut the printed material, solving the problem of uneven manual cutting in the existing technology. However, there are still defects such as feed deviation and inaccurate positioning during use.

[0004] Therefore, it is urgent to research and develop a roll-to-flat printer with a simple structure to solve the above technical problems. Summary of the Invention
