This utility model relates to the field of paper-
plastic packaging technology and discloses a die-
cutting device for the outer periphery of a paper-
plastic packaging box. The die-
cutting device includes a
processing table and a support frame set on the top of the
processing table. A first motor is fixedly connected to the inner side of the support frame. An adjustment component is set inside the support frame. This utility model facilitates flexible adjustment of the cutter position by setting the adjustment component, thereby enhancing the flexibility of the
processing operation. The cutter can be easily moved horizontally by the first
threaded rod, moving block,
fixed frame, sliding frame, fixed block, and mounting plate, and the cutter can be easily raised and lowered by the cooperation of the second
threaded rod and the second connecting rod, thereby realizing the die-
cutting operation. The limiting component can be used to limit and stabilize stacked packaging materials. The positions of the limiting plate and the buffer plate can be easily controlled and adjusted by the cylinder, fixed plate, positioning rod, and positioning block, thereby enhancing the stability of the cutting operation.
