Aluminum foil tray filling and sealing machine
The aluminum foil cup/bowl/box filling and sealing machine is a large‑scale automated packaging device designed for sealing containers such as cups, bowls, and boxes. It integrates advanced mechanical engineering with computer control technology to provide a complete turnkey solution covering automatic loading, precision filling, and high‑quality sealing. Equipped with a PLC, pneumatic components, and intelligent digital temperature control, the machine offers high sealing strength, excellent leak‑tightness, and low failure rates, and can operate either as a standalone unit or integrated into a full production line. Widely used in the food, beverage, catering, daily chemical, and pharmaceutical industries, it is suitable for liquid beverages (e.g., milk tea, juice, milk, yogurt, carbonated drinks), pastes and sauces (jam, meat paste, hotpot base, sesame paste, honey), granular foods (spicy crayfish tails, snails, wet pet food, snacks), and prepared dishes (instant meals, cooked food, bird’s nest, duck blood). The standard process flow runs: automatic container loading → filling (1‑3 times) → UV sterilization → film feeding → first heat sealing → second heat sealing → film cutting → waste recovery → discharging. The sealing system uses constant‑temperature hot‑pressing in two steps for firm, neat seals, while the filling system employs a piston‑type volumetric filler with adjustable volume for high accuracy; some high‑end models also include a CCD vision inspection system for online seal‑integrity checking and automatic rejection of defects. Core advantages include: high‑precision filling driven by a servo motor with PID control, achieving ±0.5g accuracy and using a three‑stage progressive mode (fast‑slow‑stop) for viscous products to prevent overflow; intelligent sealing technology with ±1℃ temperature control, compatible with aluminum foil and composite films, reaching 50N/15mm sealing strength with real‑time pressure adjustment to avoid bubbles or damage; and flexible production with rapid changeover between container sizes (50ml to 500ml) without replacing nozzles, plus storage of up to 100 filling parameter sets for quick recipe recall.
