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.

• Properly oriented caps descend through chute to distribution disc

• Improperly oriented caps automatically return to storage hopper

3. Capping System

• 10-head rotary capping mechanism with vacuum pickup

• Precise cap placement and application

• Torque-controlled tightening with safety protection

4. Discharge System

• Capped bottles guided along contour plate to discharge star wheel

• Final transfer to output conveyor for subsequent processing

System Advantages

• High Precision: Accurate bottle positioning and cap application

• Reliable Performance: Robust construction for continuous operation

• Flexible Operation: Adjustable parameters for various bottle and cap specifications

• Safety Assurance: Multiple protection systems prevent equipment damage and ensure operator safety

• Hygienic Design: Compliant with pharmaceutical and food industry sanitation requirements

The BPX-300 represents a sophisticated capping solution that combines precision engineering with intelligent automation to deliver reliable, efficient performance for modern production facilities requiring high-volume, high-quality capping operations.
