Description

Eight Head ROPP Screw Capping Machine is a high-speed, precision-engineered piece of equipment designed for sealing Roll-On Pilfer Proof (ROPP) and screw caps onto a variety of bottles, including glass, PET, HDPE, LDPE, and plastic containers. Widely used in industries such as pharmaceuticals, food and beverages, cosmetics, chemicals, distilleries, and pesticides, this versatile machine is built for efficiency, durability, and compliance with Good Manufacturing Practices (GMP). Below is a detailed description of its features, operation, and specifications based on available information.

Cap Feeding: ROPP or screw caps are loaded into a vibratory bowl or orientation unit, which aligns them correctly and feeds them into the delivery chute.

Bottle Positioning: Bottles are fed via a conveyor belt to an in-feed star wheel, which aligns them under the eight capping heads.

Capping Process: Each capping head picks a cap from the chute, descends onto the bottle, and uses four rollers to skirt, spin, thread, and seal the cap. Two rollers form the tamper-evident skirt, while the other two create precise threads on the bottle neck.

Output: Sealed bottles are transferred to the exit star wheel and proceed along the conveyor for further processing.

Working Principle of Eight Head Ropp 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.
