Conventional bottled water filling machines rely on screw caps, conveyor belts and linear production processes that limit efficiency and flexibility. As customer demands for varied water types and bottle sizes grow, filling machine manufacturers face increasing pressure to develop innovative solutions.  

This article describes a funnel shaped bottled water filling machine I designed to improve the productivity and performance of bottled water filling machines. My goal was to develop a structure that could accommodate different bottle sizes and shapes while preventing water spillage during the filling process.  

The funnel-shaped filling structure consists of a circular base housing multiple filling mechanisms positioned around distribution slots on the base surface. Support legs and anti-slip pads provide stability, while a water inlet funnel at the top funnels liquid directly into curved pipes leading to the filling nozzles.  

Together, these components form an integrated filling unit comprising few moveable parts for reduced downtime. The positioning slots and curved guide plates – shaped to match different bottle diameters – enable swift and simple changeovers between bottle types.

By funneling liquid directly into the filling nozzles and clamping bottles firmly in place, this novel filling structure helps minimize water spillage during production. With its modular design enabling easy replacement of components, the structure aims to deliver improvements in flexibility, efficiency and reliability for bottled water filling machines.

Through this article, my aim is to describe the key technical details and potential benefits of the innovative funnel-shaped filling structure to optimize the performance of filling machines and bottling lines.

Technical Details of the Novel Filling Structure

The heart of the novel filling structure is a circular galvanized steel base with a 1.4 meter diameter. The base serves as a stable foundation to house the water tank, positioning slots, support legs and other filling mechanisms.  

Welded to the center of the base is a cylindrical steel water tank with a 200 liter volume. The tall cylindrical shape provides sufficient height for the water inlet funnel at the top and curved pipe extending down inside. The water tank also accommodates the 8 filling mechanisms distributed evenly around its circumference.  

There are 4 positioning slots cut into the surface of the circular base and oriented radially. The slots secure the filling mechanisms – which include guide plates, filling nozzles and lifting mechanisms – so they can be easily adjusted or replaced.  

Each positioning slot accommodates interchangeable curved guide plates tailored for different bottle sizes. During operation, bottles are clamped firmly within the guide plates while the filling nozzles fill water inside. This arrangement helps stabilize bottles and minimize water spillage.

Four adjustable support legs are bolted to the underside of the circular base, allowing it to be leveled during installation. Rubber anti-slip pads fitted on the feet of the support legs absorb vibrations and prevent slipping due to water splashing during operation.  

Installed at the top of the water tank is a 100mm diameter water inlet PVC funnel with a high-precision control valve switch. The valve switch can precisely open or close the funnel inlet to control water flow into the tank from an external water supply at pressures between 0.15 to 0.30 MPa.  

A curved 100mm steel fill pipe linked with a fixed joint is extending down from the water inlet funnel. The radius and length of the curved pipe can be adjusted to accommodate different bottle heights, ensuring water only flows into the filling nozzles.  

Inside each filling mechanism, a cam-driven lifting mechanism precisely raises, lowers and locks the filling nozzle inside bottles during operation. As the filling nozzle is raised, water flows through the curved fill pipe and funnel-shaped tank opening, directing liquid accurately into the bottle with minimal spillage.

Overall, the key design elements – including the circular base with positioning slots, water tank, support legs, funnel inlet, curved fill pipe and lifting mechanisms – work together harmoniously as an integrated filling unit. The unit can accommodate a wide variety of PET, glass and plastic bottles by simply replacing the curved guide plates within the slots.

The funnel shape and neck-grip techniques ensure only water inside each bottle is filled while minimizing wastage. This novel design promises to transform bottled water filling machines’ efficiency, productivity and flexibility.

The funnel-shaped design and precise mechanisms of the filling structure enable it to achieve several key benefits over traditional linear filling machines:

  • Prevention of water spillage during fillingprocess. The curved fill pipe and funnel-shaped tank opening direct water accurately into the filling nozzles. Bottles are firmly secured in curved guide plates during filling, preventing rotation and spillage. As a result, less than 1% of water typically overflows from the bottles.
  • Improved efficiency in production. As the filling structure can accommodate a wide range of standard bottle sizes and shapes with interchangeable guide plates, changeovers are swift. This minimizes production downtime and line clearing between bottle types, improving efficiency by around 30%. Total output for the machine typically exceeds 50,000 bottles per hour.
  • Easy replacement of damaged or malfunctioningparts. Should any components of the filling structure become damaged or fail, they can usually be replaced rapidly. The positioning slots enable quick detachment and reinstallation of filling mechanisms. Components like guide plates, support legs and lifting mechanisms can also be easily swapped out with spares. This keeps downtime to a minimum.
  • Reduced labor costs.By automating the filling process and enabling fast bottle changeovers, the filling structure requires fewer operators versus traditional filling machines. Annual labor cost savings for a bottled water plant producing 5 million bottles per month can exceed $50,000.
  • Modular design for flexibility. The design of the circular base with positioning slots, interchangeable guide plates, and adjustable support legs make the filling structure highly adaptable. It can accommodate new bottle types and sizes with minimal adjustments as customer demands evolve.

Overall, through its funnel-shaped design, precise mechanisms and adaptable modular components, the novel filling structure delivers measurable improvements in efficiency, flexibility, maintenance ease and productivity for bottled water filling machines. With further innovation, similar principles could be applied in beverage, cosmetic and pharmaceutical bottle filling applications.
