20-40 bottles/min Plastic Bottle Four-Wheel Capping Machine

Four-Wheel Capping Machine Product Introduction 

The 20-40 bottles/min Plastic Bottle Four-Wheel Capping Machine provides a reliable, high-speed solution for automatic sealing of plastic bottles in medium- to large-scale production lines. Featuring four synchronized capping wheels, precision torque control, and an adjustable conveyor system, it can handle various bottle shapes, including round, oval, or uniquely designed containers. The machine is suitable for industries such as beverages, cosmetics, personal care, household chemicals, and light industrial liquids. Its stainless steel construction, user-friendly PLC interface, and minimal maintenance requirements make it perfect for factories seeking consistent cap torque, uniform sealing, and continuous high-volume operations.

Working Principle：

Bottles are fed onto the conveyor and guided by adjustable rails. Four synchronized capping wheels descend to apply torque and seal each bottle cap. Sensors ensure correct bottle alignment and cap detection. The torque system adjusts automatically to maintain consistent sealing quality across different bottle sizes and cap types. Completed bottles are then discharged for labeling or packaging.
