Combined PJC-800 + Rotary Ejector Complete Cold Glue QC Solution for E-Commerce Cartons

This integrated solution combines PJC-800 infrared glue gun detector and high-speed rotary ejector, forming a full closed-loop quality control set based on linkage signal transmission principle. PJC-800 monitors dot and line cold glue spraying in real time at the glue gun outlet, capturing missing glue, broken tracks and offset spraying instantly. Once defects are identified, the sensor transmits synchronous electrical signals to the rotary ejector servo controller; the rotary baffle acts within milliseconds to separate defective cartons during high-speed conveying without production line pause. All detection and rejection data unifies on one shared touchscreen for centralized management.

The core advantages of the combined set include early defect interception, zero production interruption and wide material compatibility. The PJC-800 sensor adapts laminated, UV and silver cardboard commonly used for e-commerce packaging, while the rotary ejector runs stably at 320m/min matching the detector’s maximum speed limit. The whole set requires only one-time wiring and parameter debugging during installation, supporting direct retrofitting on old folder gluers without large reconstruction, greatly shortening equipment upgrade downtime and investment recovery cycle. Compared with separate purchase and independent debugging of two machines, the matched combo reduces compatibility failure risks and after-sales maintenance difficulty.

It targets mass production of express e-commerce cartons, cosmetic folding boxes and wine gift packaging with cold glue spraying processes. E-commerce packaging factories facing huge order volumes rely on this set to eliminate offline glue inspection labor and reduce carton opening return losses caused by poor gluing. The modular layout reserves expansion space for later addition of barcode or vision detection modules, allowing factories to upgrade QC functions step by step according to business growth. This cost-effective one-stop cold glue QC combo has become the mainstream transformation choice for medium and large printing packaging enterprises.
