Easy Retrofit Design — Add KQ‑VD720 to Your Existing Folder Gluer

Many printing factories want vision‑based full inspection but hesitate to replace complete folder‑gluer machines due to high investment and long‑downturn losses. KQ‑VD720 camera detection system is purpose‑built for inline retrofitting on most new and legacy folder gluers.

The camera unit supports top‑mount or side‑mount installation according to machine layout. Adjustable objective distance ranges from 100‑999 mm, adapting different carton heights and conveyor structures. Only simple bracket fixing, signal‑line connection and template setup are needed; destructive frame reconstruction is not required.

It can link seamlessly with Keqi rotary ejector or piston kicker to build closed‑loop “detect‑and‑reject” workflow. Touch‑screen HMI unifies parameter setting, real‑time image preview and defect‑data statistics.Small‑medium workshops and large printing groups both can upgrade quality‑control capacity with limited budget. Installation and commissioning can be finished within one shift, minimizing production halt losses for packaging converters.
