Description

Four Head ROPP Screw Capping Machine is an automated packaging machine designed for high-speed, precise sealing of bottles with aluminum ROPP or screw caps. It is widely used in industries such as pharmaceuticals, food and beverages, cosmetics, chemicals, and distilleries for capping bottles containing products like dry syrups, edible oils, shampoos, hand sanitizers, and spirits. The Four Head ROPP Screw Capping Machine is a versatile, precision-engineered machine built to apply tamper-evident ROPP caps or screw caps to glass, plastic, or LDPE bottles of various shapes and sizes. It is constructed with a sturdy stainless steel (often SS304) frame, ensuring durability, hygiene, and compliance with Good Manufacturing Practices (GMP). The machine is fully automatic, minimizing operator intervention, and is designed for integration into high-speed production lines.

The Four Head ROPP Screw Capping Machine is a high-efficiency, automated solution for sealing bottles with tamper-evident caps. Its robust stainless steel construction, adjustable settings, and compatibility with various industries make it a reliable choice for medium to high-volume production lines. With advanced features like PLC controls and safety mechanisms, it ensures precision, safety, and compliance with industry standards.

Material Requirements: ROPP capping requires bottles with hard necks to withstand the pressure of thread formation.

Setup Complexity: While changeovers are quick, initial setup for different cap sizes may require a qualified engineer.

Working Principle of Four 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.

Applications of Capping and Sealing Machine

Advantages of Four Head Ropp Screw Capping Machine

High Efficiency: Four-head design increases capping speed compared to single-head machines.

Tamper-Evident Security: ROPP caps provide visible proof of tampering, enhancing consumer safety.

Versatility: Handles a wide range of bottle and cap sizes with minimal adjustments.

Durability: Stainless steel construction ensures long life and resistance to corrosion.

Ease of Use: Intuitive controls and quick setup reduce operator training time.

Key Components of Four Head Ropp Screw Capping Machine

Construction and Design:
- Material: Made of stainless steel (SS304) with a matte finish for corrosion resistance and easy cleaning. Exposed parts may also include aluminum, Delrin, or silicon for durability.
- Adjustable Height: Equipped with an adjustable height system to accommodate different bottle sizes.
- Compact and Modular: The machine is self-supported with a compact design, featuring a conveyor, star wheels, and a cap-feeding system for seamless operation.

Capping Mechanism:
- Four Capping Heads: The machine has four rotating capping heads, each equipped with rollers to apply ROPP or screw caps with precise torque.
- Tamper-Evident Sealing: ROPP caps are crimped around the bottle neck, forming threads and a tamper-evident band that breaks upon opening, ensuring product security.
- Torque Control: Adjustable torque settings allow customization for different cap materials and bottle types, preventing cap damage or over-tightening.

Operation Process:
- Bottle Feeding: Bottles are fed from a filling machine or unscramble onto a stainless steel slat conveyor.
- Cap Placement: Bottles pick up caps from a delivery chute or cap-feeding bowl as they move into an in-feed star wheel.
- Capping: The star wheel aligns bottles under the four Capping heads, where rollers press and form the cap onto the bottle neck, creating threads and a secure seal.
- Exit: Sealed bottles move to an exit star wheel and proceed to the next process.
- No Bottle, No Cap System: A sensor stops the machine if no bottle is present, preventing cap wastage.

Performance:
- Speed: Capable of capping 65 to 80 bottles per minute, depending on bottle and cap size. Some models claim up to 100–120 bottles per minute with optimized settings.
- Cap Size: Supports ROPP or screw caps ranging from 19 mm to 38 mm in diameter and 15 to 18.3 mm in height.
- Container Compatibility: Suitable for round, square, or flat bottles made of glass, plastic, or LDPE.

Advanced Features:
- PLC and HMI: Optional programmable logic controller (PLC) with a 7-inch color touchscreen for error messaging and control.
- Cap Feeder Options: Vibratory bowl, mechanical orientator, or waterfall-type elevator for continuous cap feeding.
- Safety Features: Includes safety clutches on star wheels to prevent bottle breakage, emergency stop buttons, and optional toughened glass or acrylic safety cabinets.
- Quick Changeover: Minimal downtime for switching between bottle and cap sizes, with adjustable conveyor guides and universal couplings.
- GMP Compliance: Designed for hygienic operation, with easy-to-dismantle parts for cleaning.

Optional Add-Ons:
- Laminar Air Flow for class 100 cleanroom applications.
- Magnetic hysteresis clutch for precise torque control.
