Description

Technical Field

[0001] This utility model relates to the field of label cutting technology, specifically a label die-cutting tool. Background Technology

[0002] The printed label roll is a continuous whole, while the actual label used must be a single individual with a specific outline. Whether it's a simple rectangle or a complex irregular shape, a high-precision die-cutting process is needed to accurately define its boundaries, ensuring that the label can be completely and accurately peeled from the backing paper and affixed to the product. Without die-cutting, the label cannot fulfill its basic function as an "identifier."

[0003] Die-cutting is a crucial process in label printing and post-processing. Its core function is to use precision cutting tools to cut, partially cut, or fully cut the material into a predetermined shape. The performance of the die-cutting tools directly determines the cutting quality, production efficiency, and production cost of the label products.

[0004] In the prior art, there is a Chinese patent with authorization announcement number CN222904319U entitled "A Die-cutting Device for Bottle Labels". This patent discloses a die-cutting device for bottle labels, including a support, an unwinding shaft and a waste rewinding shaft mounted on the support, and a die-cutting structure located between the unwinding shaft and the waste rewinding shaft. The die-cutting structure includes a die-cutting worktable, a telescopic electric rod, a die-cutting blade holder, and a die-cutting blade. The die-cutting worktable is fixed on the support, the telescopic electric rod is fixed on the top of the support, and the die-cutting blade holder is fixed on the piston shaft of the telescopic electric rod. The die-cutting blade is fixed on the bottom surface of the die-cutting blade holder. A label channel is provided on the die-cutting worktable, a fan is provided on the top surface of the die-cutting blade holder, and an air outlet is provided on the bottom surface of the die-cutting blade holder.

[0005] The aforementioned patents can effectively and quickly die-cut label rolls, effectively realizing the die-cutting process and improving die-cutting efficiency. Existing technologies, including the aforementioned patents, can meet the die-cutting needs of labels to a certain extent. However, in actual operation, when the die-cutting blade performs the die-cutting operation, significant friction inevitably occurs between the blade and the label. When the die-cutting blade resets, this friction can cause the label to lift up, affecting subsequent die-cutting operations. Utility Model Content
