[0002] Paper-plastic packaging boxes are environmentally friendly packaging containers made from plant fibers through hot pressing and molding. They are biodegradable, shockproof, pressure resistant, breathable, and freshness-preserving, and are widely used in food, industry, agriculture, medical and other fields.

[0003] Die-cutting the outer edge of paper-plastic packaging materials effectively removes excess burrs, improves product quality, and facilitates subsequent assembly and use. Currently, most cutting processes use a straight-up-down cutting method. When cutting the other side of the material, the entire material needs to be moved, and stacks of paper-plastic packaging materials are prone to becoming scattered, requiring reorganization before processing. This increases the complexity of the processing operation and affects production efficiency. Utility Model Content

[0027] Working Principle: During use, stacks of neatly arranged paper-plastic packaging materials are placed on the processing table 1. Driven by the first motor 3, the first connecting rod 7 drives the first threaded rod 41 to rotate under the support of the support frame 2. This causes the moving block 42 to move the fixed frame 43. With the connection of the fixed frame 43, another moving block 42 slides under the support of the stabilizing rod 6, improving the stability of the movement. The movement of the fixed frame 43 drives the sliding frame 44, the fixed block 8, the second threaded rod 9, etc. to move synchronously. With the connection of the mounting plate 12, the position of the cutter 13 can be easily adjusted as needed without moving the paper-plastic packaging materials, enhancing the convenience of die-cutting. Driven by the third motor 15, the positioning rod 53 drives the two positioning blocks 54 to flip, which in turn causes the limiting plate 55 to flip the buffer pad 14. This causes the limiting plate 55 and the buffer pad 14 to... Placed above the packaging material, driven by cylinder 18, the third connecting rod 17 causes the fixing plate 16 to descend, which in turn causes the fixing plate 16 to cause the two support plates 51 to descend. The support plates 51 then cause the support base 52, the third motor 15, the positioning rod 53, the positioning block 54, the limiting plate 55, and the buffer pad 14 to descend. When the limiting plate 55 causes the buffer pad 14 to contact the top of the stacked packaging material, it presses and limits it, improving the stability of the processing and cutting. Driven by the second motor 11, the second connecting rod 10 causes the second threaded rod 9 to rotate, which in turn causes the fixing block 8 to move the sliding frame 44. With the connection between the mounting plate 12 and another fixing block 8, the other sliding frame 44 slides under the limit of the fixing frame 43, which facilitates the mounting plate 12 to drive the cutter 13 to rise and fall, thereby realizing the cutting of the paper and plastic packaging material.
