Description

Technical Field

[0001] The utility model relates to a die-cutting device, in particular to a die-cutting device for producing food packaging paper, belonging to the technical field of food packaging paper production. Background Art

[0002] Honeycomb packaging paper has good protective properties and can effectively protect food from damage during transportation and storage. Its lightweight design and reasonable structure provide good cushioning effect, which can reduce the damage caused by vibration or collision during transportation. Honeycomb packaging paper has good air permeability and can control the air permeability of food, which helps to keep the food fresh and healthy.

[0003] However, when the existing die-cutting machine is in use, the die-cutting roller of the equipment can cut the packaging paper into a specific shape through appropriate pressure. Before cutting, the packaging paper can be conveyed to the die-cutting roller when the roll rotates. When the packaging paper on the roll is put away, the roll must be removed from the paper rack by tools, which is inconvenient to operate and is not conducive to improving the use efficiency of the die-cutting machine.
