Description

Technical Field

[0001] The utility model relates to the technical field of die cutting, in particular to a waste top flat knife die cutting device. Background Art

[0002] Waste removal from a die-cutting machine refers to the process of separating excess material or waste from the product during the die-cutting process. Waste removal not only increases the cost of materials, but also increases the cost of manpower and equipment. There are three main ways to remove waste from holes in existing flat knife die-cutting machines: (1) Self-priming waste mold: Use a self-priming waste mold to push the hole waste into the waste slot inside the self-priming waste mold, and then use an air gun to blow away the hole waste to separate the product and the hole waste. However, the self-priming waste mold is only suitable for smaller hole waste, and the use scenario is limited; (2) Lifting up and pulling down: Use auxiliary waste tape and waste adhesive film to stick the hole waste away, but auxiliary materials are needed, resulting in material waste, increased working hours, and prone to product back-sticking, glue overflow, poor glue pulling and other phenomena.

[0003] Patent publication number CN114571533A discloses a die cutter for cutting small round hole wastes, the die cutter comprises a die cutter upper plate and a die cutter lower plate that match each other; the die cutter upper plate is provided with at least one row of round hole blades and at least one row of round hole top waste pins parallel to the position of the round hole blades; the die cutter lower plate is provided with at least one row of blanking holes corresponding to the position of the round hole top waste pins.
