Automatic Irregular Bottle Capping Machine Product Introduction
Automatic Irregular Bottle Capping Machine for Liquor Packaging is designed for automatic sealing of irregular bottles, plastic bottles and various liquid packaging containers.
The machine adopts a special bottle positioning system and automatic screw capping structure, allowing stable operation even with non-standard bottle shapes. It integrates cap feeding, bottle positioning, capping and conveyor transportation functions into one complete packaging solution.
With adjustable capping parameters and reliable control performance, this automatic bottle capper ensures consistent sealing quality and improves production efficiency. It is widely used in liquor, beverage, food, cosmetic and daily chemical industries requiring automatic packaging of special-shaped bottles.


System Overview
The Automatic Irregular Bottle Capping Machine is developed for manufacturers who need flexible sealing solutions for different bottle shapes.
The system mainly consists of:
- Automatic cap feeding structure
- Bottle positioning mechanism
- Capping chuck
- Conveyor belt system
- Electric eye sensor
- Motor drive system
- PLC control panel
- Stainless steel machine frame
The machine automatically transfers bottles through the conveyor, detects bottle position, places caps and completes the screw capping process.
Working Principle
The empty or filled bottles enter the capping area through the conveyor system.
The automatic feeding mechanism supplies caps continuously and transfers them to the capping position. The electric eye sensor detects the bottle position, and the positioning structure keeps the bottle stable during operation.
The capping chuck moves downward and rotates to tighten the cap with controlled torque. After completing the sealing process, the finished bottles are transported to the next packaging stage.
Working Process:
Bottle Feeding → Cap Feeding → Bottle Positioning → Cap Placement → Automatic Screw Capping → Finished Bottle Output
