HX120 Dual Sequence Four-Corner Round Trimming Pneumatic Feeding Equipment

The HX120 Automatic Four-Corner Round Trimming Machine is professional rounding equipment for stacked paper and card materials, with a maximum trimming height reaching 120mm. It adopts a unique dual-sequence trimming process: two corners are trimmed first, and the material is accurately repositioned to process the other two corners. This processing method effectively solves the problem of inconsistent corner dimensions caused by tight material tolerances. Equipped with a high-power pneumatic driving system and automatic feeding structure, the equipment delivers stable and safe operation, producing burr-free, smooth and uniform rounded corners for stacked paperboards, cards and other thick layered materials.

1. Four-corner rounding trimming for various cards, membership cards, access control cards and business cards
2. Round corner processing for stacked book cover boards, packaging paperboards and thick printed sheets
3. Post-processing rounding for photo albums, hardcover notebooks, gift boxes and paper packaging products
4. Mass corner trimming production in printing factories, card manufacturing plants and packaging processing workshops

The machine breaks the limit of conventional corner trimmers with a maximum trimming height of 120mm, which can process high stacks of materials at one time and greatly improve production efficiency. The dual-sequence trimming technology realizes accurate secondary positioning, thoroughly avoids uneven corner size and dimensional deviation caused by material tolerance. The pneumatic driving system ensures stable trimming force, effectively removes burrs and irregular edges to obtain consistent smooth rounded corners. With automatic feeding and safety protection design, it reduces manual operation risks, keeps long-time continuous stable operation and lowers product defective rate.

1. 120mm maximum trimming height supports one-time trimming of high stacks of cards and paperboards to boost productivity
2. Dual-sequence trimming technology accurately repositions materials to guarantee uniform corner dimensions
3. Burr-free smooth rounded corners effectively eliminates irregular edges even for thick stacked materials
4. High-power pneumatic drive system provides stable trimming force for long-term continuous operation
5. Automatic feeding structure reduces manual feeding work and optimizes production procedures
6. Built-in safety protection design ensures precise trimming while improving workshop operational safety
