DS180/2 Double-Row Back-Sealing Automatic Packaging Machine
The DS180/2 Double-Row Back-Sealing Automatic Packaging Machine represents a significant advancement in high-efficiency sachet production for granular, powdered, and liquid products. Engineered for demanding production environments, this machine integrates film forming, precision dosing, sealing, and cutting into a robust, multi-row system. Constructed with 304 stainless steel on all product-contact surfaces, it guarantees superior hygiene and corrosion resistance. Designed around a multi-row collar forming structure with a capacity up to 180 mm and supported by reliable photoelectric tracking, the DS180/2 delivers exceptional consistency in bag shape and seal integrity, making it an ideal solution for high-throughput, small-dose packaging operations that demand both speed and unwavering quality.
Product Features
Enhanced Productivity with Double-Row Output: The dual-column design is a cornerstone of this machine’s efficiency, effectively doubling output capacity without compromising operational stability. Capable of sustained high-speed performance at 30 to 50 bags per column per minute, it provides a scalable foundation for production lines that require reliable, continuous operation to meet growing market demands.
Superior Seal Integrity with Back-Sealing Technology: Utilizing a sophisticated back-sealing mechanism with twisted-edge adhesive sealing, the machine produces sachets with exceptionally clean and secure seals. The straight horizontal sealing pattern, featuring a precise 1.2 mm spacing, ensures a uniform professional appearance. Controlled sealing widths—5 mm for vertical and 8 mm for horizontal seals—further enhance the mechanical strength and consistency of every package, significantly reducing the risk of leaks or seal failures.
Precision Tracking and Consistent Bag Formation: Equipped with a high-sensitivity photoelectric eye for accurate film mark detection, the system minimizes material misalignment and waste, particularly when using pre-printed packaging films. A variable-frequency motor drives the bag-pulling mechanism, enabling precise control over bag length and ensuring smooth, stable film transport across the entire speed range, from startup to maximum operational velocity.
Intelligent Control and Operational Reliability: At the heart of the machine is a user-friendly control system combining a clear text display with a robust OMRON PLC. This setup enables real-time error prompting and system self-diagnosis, facilitating quick troubleshooting and minimizing downtime. Dual PID temperature controllers (OMRON) provide exacting thermal management for the sealing jaws, ensuring optimal seal quality across various composite film materials and improving overall production yield.
Versatile and Hygienic Metering Solutions: To accommodate a diverse range of products, the DS180/2 can be configured with specialized, high-precision metering devices. Options include dedicated systems for granules/particles, free-flowing powders, or viscous liquids. Each metering unit is engineered for repeatable filling accuracy, and like the main machine, all wetted parts are fabricated from 304 stainless steel, upholding the highest standards of hygiene and durability.
Robust Industrial Construction: Built for longevity in industrial settings, the machine features a rigid frame and utilizes high-quality Taiwan AIRTAC pneumatic components for dependable operation. The separation process employs a blade method without a flash device, coupled with pattern cutting, to deliver neatly trimmed bag edges and a polished final product presentation, batch after batch.
