Description

Technical Field

[0001] The utility model relates to the technical field of flexographic printing, in particular to a unit-type flexographic printing device. Background Art

[0002] A unit-type flexographic printing unit, also known as a unit-type flexographic printing press, is a highly efficient and versatile printing device that can complete multiple processes, including printing and die-cutting, in a single pass. Depending on the configuration, it can also perform double-sided printing, number printing, and UV curing varnishing. Unit-type flexographic printing machines are widely used in the printing of labels, flexible packaging, cartons, and paper cups. For example, label flexographic printing machines are primarily used for printing paper self-adhesive labels and wine labels; flexible packaging flexographic printing machines are used for printing paper packaging materials, such as disposable medical product bags and tea wrappers; and carton and paper cup flexographic printing machines are primarily used for printing cardboard-based rigid packaging.

[0003] In modular flexographic printing systems, the rewinding mechanism utilizes a single-spool system. Once a roll of material is printed, the machine must be stopped to remove the finished reel, replace it with a new, empty reel, and then restart the machine to rewind the next roll. This approach significantly disrupts the production process and reduces efficiency. Utility Model Content
