QYGC-850-600 Flatbed + Side Dual-Pressure Shaped Carton Packing Machine Strapping Application
In the industries of carton color printing, cardboard processing, and packaging配套, irregularly shaped cardboard, loose corrugated cardboard pieces, and irregular paper stacks have always been challenging for post-processing bundling. Conventional top-strap bundling machines struggle with uneven heights, easy rebound, and varying widths of irregularly shaped cardboard, often leading to issues like stack loosening, uneven bundling tension, strap slippage, and cardboard misalignment. Manual sorting and compaction are time-consuming, resulting in poor bundling consistency, which directly impacts storage stacking and vehicle loading efficiency.  The QYGC-850-600 flat platform + side dual-pressing irregular cardboard bundling machine is specifically designed for irregular cardboard with a side-bundling solution. It features a flat support platform combined with a dual-side synchronous pressing structure to address the pain points of rebound and loosening in irregular cardboard, widely applicable for automated bundling operations in cardboard factories, color box factories, packaging配套, and再生资源回收 scenarios.

The frame specification of this machine is 850 × 600mm, and the flat workbench is flat and stable, making it convenient for workers or assembly line conveyors to directly load materials. Long, irregular cutting, irregular notches, and slanted cardboard can be placed smoothly without hanging or collapsing edges. The core advantage lies in the dual pressure structure on the side, where the cylinders on both sides synchronously push the material to the center and compact the paper stack. The irregular shaped cardboard that is fluffy, warped, and has uneven edges is first straightened and shaped before being hot-melt tied, effectively offsetting the rebound force of the corrugated cardboard itself. The bundling is tight and uniform, the stacking is square and not skewed, and the packing tape is not easy to slip or loosen. The device supports compatible use of PP strapping and PET plastic steel strapping, with adjustable strapping force and free switching between single and double strapping modes. It can operate in multiple modes including foot pedal, semi-automatic, and online automatic, with low entry barriers. New employees can operate stably with simple training. In the cardboard production workshop, it is suitable for stacking and bundling shaped color box blanks, shaped liners, partitions, honeycomb cardboard, and irregular gaskets after die-cutting; In the packaging supporting factory, customized loose cardboard, matching corner protection cardboard, and mixed batch cutting paper pieces of different sizes can be processed; In the storage and recycling process, it is suitable to concentrate and compact miscellaneous sized cardboard and scraps paper stacks, compress the volume, and reduce storage and logistics transportation costs. The equipment can be independently placed at the cutting station and inspection station for separate operation, or can be connected to the cardboard conveyor line and the back end of the die-cutting machine, embedded in the entire post packaging production line, to achieve continuous automated production of cutting, sorting, and pressure bundling, reducing the heavy process of manual stacking and bundling, lowering labor costs, and stably producing paper stack packages with uniform quality. The overall structure of the machine is solid, and the conveyor belt is located on the side, so it will not be scratched by cardboard protrusions or irregular edges. Compared with conventional top press models, the failure rate of the card belt is significantly reduced, and maintenance is simple. For small and medium-sized packaging enterprises with multiple order styles, irregular cardboard shapes, and frequent switching of specifications, this model has strong versatility. It does not require frequent mold changes and can be adapted to different shaped paper parts by adjusting parameters, balancing flexible production and packaging efficiency. It is a cost-effective automation solution for the subsequent bundling process of shaped cardboard.
