High-Speed Rotary Ejector – Synchronized Defect Removal for Ultra-Fast Folder Gluer Lines

The working principle of Keqi high-speed rotary ejector relies on servo motor precision angle control. After receiving defect trigger signals from glue sensors, barcode detectors or vision systems, the servo drives the rotary baffle to swing within 0.05s response delay, diverting defective cartons to the rejection channel without blocking normal conveying flow. Soft polyurethane contact baffles avoid scratching delicate printed surfaces, embossing and UV coatings on high-end gift boxes, solving the scratch defect pain point of rigid metal rejection structures.

Core advantages include ultra-high speed adaptability and stable continuous operation under 350m/min line speed, unmatched by traditional piston kickers for fast production lines. The ejection angle freely adjusts according to carton size from mini drug boxes to large corrugated gift cartons, realizing targeted separation without mixing qualified and defective products. The sealed servo drive unit resists ink dust and paper scraps from printing workshops, extending service life and reducing spare part replacement frequency. The equipment supports plug-and-play signal docking with all Keqi detection sensors, requiring only simple wiring without complex program debugging.

Primary application scenarios match high-speed mass production lines of liquor packaging, cosmetic boxes and large e-commerce cartons equipped with PJC-800, GJC-600 or KQ-VD720 inspection systems. Large printing factories with 24-hour continuous production prefer rotary ejectors to eliminate carton jamming failures caused by slow piston rejection mechanisms. It can be retrofitted on any existing folder gluer without frame modification, realizing automatic closed-loop quality control of "detection + automatic rejection". By removing manual sorting stations for defective cartons, enterprises cut labor expenditure and avoid secondary damage to finished packaging during manual picking.
