20-30 pcs/min Detergent Plastic Bottle Screw Capping Machine

Capping Machine Product Introduction 

The 20-30 pcs/min Detergent Plastic Bottle Screw Capping Machine is designed for high-efficiency bottling of plastic detergent bottles with trigger spray caps. The machine integrates bottle positioning, cap feeding, and servo-driven screw capping in a fully automated system.

A vibrating cap feeder automatically aligns and delivers caps to the capping heads, while servo motors provide adjustable torque to prevent bottle or cap damage. The modular design allows the machine to share a conveyor with a filling line or operate independently. Constructed from stainless steel, it is hygienic, durable, and easy to clean. Suitable for small-to-medium detergent production lines, household cleaners, and other viscous liquid products.

Working Principle：

The 20-30 pcs/min Detergent Plastic Bottle Screw Capping Machine operates by first conveying plastic trigger spray bottles along the production line. Caps are automatically supplied and aligned via a vibrating plate feeder. When bottles reach the capping station, servo-driven screw capping heads rotate and tighten each cap with precise torque, ensuring a secure and leak-proof seal. The system is fully automatic, synchronizing bottle positioning, cap feeding, and capping actions to achieve high-speed, consistent, and reliable sealing for detergent bottles.
