Product Introduction
The DS450-4G/P/L Automatic Pouch Filling and Sealing Machine represents a pinnacle of modern packaging engineering, designed to deliver high-efficiency, stable, and precise small-dose sachet production. This advanced system is engineered for compatibility with composite packaging films and accommodates a versatile range of product forms, including particles, powders, and liquids, with configurations tailored to specific packaging requirements. Offering a flexible filling range of 1–50 ml, it is ideal for diverse production needs. At its core, the machine utilizes a sophisticated motor-crank heat-sealing bag pulling system, where a high-precision encoder meticulously coordinates film advancement and sealing actions. This integration ensures consistent bag length, impeccable seal integrity, and reliable, high-output performance. With a maximum film width capability of 450 mm and a standard bag-making specification set, the DS450-4G/P/L is expertly suited for optimized multi-lane production layouts, which are determined by specific bag dimensions and column configurations, maximizing throughput and operational efficiency.
Product Features
Optimized Sealing Structure for Unmatched Integrity
The machine boasts a robust sealing system featuring a horizontal seal width of 8–10 mm, enhanced with a single-sided diagonal mesh pattern (1 mm spacing). This design significantly strengthens seal durability and improves the overall aesthetic finish. The back seal, with a width of 4–6 mm, is executed with a clean, pattern-free surface, ensuring a neat presentation and a consistently reliable closure that withstands handling and transportation.
Precision Bag Forming with Encoder-Controlled Synchronization
Precision is paramount in pouch making. The motor-crank type heat-sealing bag pulling mechanism is governed by real-time encoder feedback. This intelligent control system perfectly synchronizes film travel with the sealing cycle, guaranteeing uniform sachet formation, exceptional dimensional repeatability, and minimized variability across extended, high-volume production runs, resulting in superior product consistency.
Broad Material Adaptability for Diverse Product Lines
Engineered for versatility, the DS450-4G/P/L is configurable to handle particles, powders, and liquids, allowing seamless integration into various production environments. For liquid packaging applications, an optional 1 mm horizontal sealing leak-proof line is available. This specialized feature enhances resistance against potential seepage during the sealing process and subsequent handling, ensuring package integrity for sensitive liquid products.
Reliable Sensing and Premium Electrical Components
Operational reliability is ensured through advanced sensing and high-quality electrical architecture. The machine is equipped with JULONG dual-color photoelectric tracking (“Ronic Eye”) for stable and accurate mark detection on printed films. Critical control components, including PLCs, contactors, and sensors, are sourced from industry-leading brands such as Schneider or OMRON, delivering consistent control performance, reduced downtime, and long-term operational dependability.
Superior Cutting Finish and User-Centric Packaging Features
Attention to detail extends to the finishing touches. An independent round-corner cutting device eliminates sharp edges, enhancing pack safety and aesthetics while controlling material waste to a minimal 2–3 mm. For end-user convenience, the machine offers customizable tear-opening options, including a point-shaped easy-tear mouth or a dual easy-tear mouth, facilitated by an independent tearing device for effortless opening.
Comprehensive Safety Configuration for Secure Operations
Safety is integrated into the machine’s design. Standard safety provisions include prominent three-color alarm lights for immediate status indication, Panasonic safety door detection switches, readily accessible emergency stop switches, and clearly labeled safety signs at all heating and mechanical action points. These features collectively support a safer working environment for daily operation and routine maintenance procedures.
