Description

Automatic Screw Capping Machine is a specialized piece of equipment designed to automatically place and tighten screw caps, lug caps, or twist-off caps onto bottles, jars, or other containers. These machines are widely used in industries such as food and beverage, pharmaceuticals, cosmetics, chemicals, and more to enhance production efficiency, ensure consistent cap application, and maintain product integrity. Automatic Screw Capping Machines are essential for modern packaging lines, offering speed, precision, and versatility. They streamline production, ensure secure seals, and cater to a wide range of industries and container types. When selecting a machine, consider production volume, cap and bottle specifications, and integration needs.

Changeover Requirements: Some machines, especially chuck cappers, require change parts for different cap or bottle sizes, which can increase setup time.

Maintenance: Regular maintenance is needed to ensure torque accuracy and prevent wear on Capping

Industry-Specific Needs: Food and pharmaceutical applications may require machines meeting stringent sanitary standards.

Working Principle of Automatic Screw Capping Machine

The filled bottles moving on conveyor belt and fed into an in feed star wheel by in-feed worm. While moving in feed star wheel, bottles pick up caps one by one from delivery chute. The descending rotary sealing heads hold bottle’s neck with desired pressure. The sealing is done in a programmed roll-on manner, accurate positioned of the caps is done mechanically by means of a rotating unscramble, to direct the caps correctly into the chute, when the chute is filled up the rotating unscramble drive is disengaged, hence, there is no chance to damage of caps. The sealing roller takes place due to rotating sealing head and transfer movement of sealing & threading rollers due to sealing cam. The sealed bottles are discharged by exist star wheel on conveyors.
