Description

Technical Field

[0001] The utility model relates to a folding device, in particular to a folding device for a circular knife die cutting machine, and belongs to the technical field of folding devices for circular knife die cutting machines. Background Art

[0002] The circular knife machine is a type of die-cutting machine. Its full name is "multi-station rotary die-cutting machine", abbreviated as rotary machine, commonly known as circular knife machine, rolling cutter machine or circular knife die-cutting machine. It performs die-cutting processing by continuous rotation in the form of a rolling cutter and is one of the most efficient types of die-cutting machines.

[0003] In the production process of circular die-cutting machines, there are many cases where the material strip needs to be folded to meet the requirements of product technology.

[0004] At present, hemming is generally performed by opening an inclined guide groove on the guide plate. This method is difficult to achieve effective hemming for some hard and non-deformable materials, which results in the hemming failing to meet product requirements.

[0005] A known Chinese public authorized patent (publication number: CN211564140U) discloses a hard material folding device for a circular knife die cutting machine, which can limit and press the material strip that does not need to be folded by setting a material pressing plate on one side of the top of the bottom plate, and gradually bend the material strip that needs to be folded by setting a folding plate on the other side, and realize the final folding by a material guide plate. By setting the folding plate, the material with a harder material and not easy to deform can be placed at a longer distance, and bend during the gradual bending and deformation process, so as to avoid the problem of material stress concentration and rebound caused by short-distance and rapid folding, resulting in unsatisfactory folding effect and affecting the product qualification rate;

[0006] The folding of hard materials is achieved through a folding plate, but in the folding process, the bent part is always in contact with the folding plate. When the material strip moves, this position slides and rubs against the folding plate, and the friction is large, which will cause scratches on the edge of the material strip, affecting the quality of the product. Therefore, a folding device for a circular knife die-cutting machine is proposed. Utility Model Content
