Automatic Rotary Screw Capping Machine BPX-300 With Centrifugal Cap Elevator
BPX-300 Rotary Capping Machine
Product Overview
The BPX-300 Rotary Capping Machine is an advanced automatic capping system independently developed by our company with reference to domestic and international similar products. This sophisticated equipment completes the entire capping process through an integrated workflow: bottles are conveyed via a belt system to an intake screw, transferred to an intake star wheel, and then guided along a contour plate to the capping star wheel where they are secured by anti-rotation belts. Caps are elevated to an orientation hopper via a centrifugal lift system, properly oriented caps descend through a chute to a distribution disc, and are then vacuum-lifted by capping heads for precise application. The capped bottles finally exit through a discharge star wheel onto the output conveyor. Incorporating cutting-edge technology with comprehensive protection and alarm systems for bottle jams, shortages, and overload conditions, this machine delivers reliable performance, scientific process flow, and compliance with national food hygiene standards.
