Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting devices, in particular to a die-cutting device for processing plastic packaging boxes. Background Art

[0002] The die-cutting device is a widely used equipment in industrial production. It is mainly used to cut raw materials such as paper, plastic, film, metal foil and other materials into the required shape and size. When processing feed packaging boxes, the plastic sheet needs to be placed in the die-cutting equipment, and cut and open holes at designated positions, and then folded to form a complete packaging box.

[0003] When using die cutting, the tool is located at the bottom of the movable die and is a ring structure, so that holes can be opened on the plastic sheet. In this case, the plastic sheet at the opening position is taken out by pressing down, and there is a great possibility that the cut waste will be embedded in the ring tool, thereby affecting the next cutting. At the same time, when the cutting is completed, the outer edge of the tool is against the side wall of the feed sheet opening, and the feed sheet may move upward synchronously with the tool. Therefore, it is necessary to design a die-cutting device that is convenient for discharging waste and removing materials. At the same time, accurate positioning is also required during die-cutting and feeding. Designing a die-cutting device that can assist in positioning can improve production efficiency.
