Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coding machines, in particular to a step-by-step automatic coding mechanism. Background Art
[0002] With the continuous improvement of industrial automation, the demand for marking and coding on production lines is also increasing. In particular, in industries such as food, pharmaceuticals, and daily chemicals, accurate information printing is required on each packaging unit to ensure product traceability and safety. Although traditional inkjet printing is widely used, it has some practical problems, such as significant environmental impact on print quality, high maintenance costs, and the complexity of ink changes.
[0003] To address these issues, ribbon printers emerged. Using thermal transfer technology, ribbon printers heat specific areas of a ribbon to create the desired characters or patterns. These printers offer clear printing, strong durability, and easy maintenance. However, in practice, existing ribbon printers still face challenges, such as uneven tape travel. At high speeds, the lack of effective control mechanisms can lead to unstable tape travel, resulting in offset or jamming of the print position.
[0004] In response to the above problems, the present application proposes an improved step-by-step automatic coding mechanism. Utility Model Content
