Description

Technical Field

[0001] The utility model belongs to the technical field of cutters, and in particular relates to a rotary die-cutting cutter with mutually bottom rollers. Background Art

[0002] In the die-cutting industry, roll materials are a common packaging method, typically used in automatic placement machines. Products are generally required to maintain a certain degree of accuracy relative to the edge of the strip, ranging from + / -0.1mm to + / -0.5mm. Using existing conventional dies, the product contour blade and the strip cutting blade are manufactured on the same tool. A layer of backing film is added under the strip to serve as a base for the trimming blades, which increases product costs. If a separate trimming die were used, using the product material as the base film to cut the strip, the two dies would need to overlap to ensure the product's accuracy relative to the strip edge, affecting product dimensional accuracy and production efficiency. Workers would need to constantly monitor the overlapping cutting dimensions. To address this issue, we have proposed a rotary die-cutting tool with two rotating rollers acting as base rollers. Utility Model Content

[0003] The purpose of the utility model is to provide a rotary die-cutting tool with mutually bottom rollers. The opposite sides of the gears are accurately positioned by using slots and bosses. During production, the contour of the product is cut normally, and the trimming blade below cuts the material strip and rewinds it. There is no need to add a separate bottom film, which can reduce costs. At the same time, the positioning slot is used to ensure the tool matching accuracy, and no operator adjustment is required, which can effectively improve the machine operation efficiency.
