Doypack premade pouch packing machine

Workflow of a Doypack Premade Pouch Packing Machine

System Initialization Phase
• Safety Self-Check: Automatically verifies the air pressure system (0.5-0.7MPa), heating module (±1℃ temperature control accuracy), and servo positioning system during startup.
• Process Parameter Configuration: Sets bag parameters (three-side sealing/four-side sealing), filling accuracy (adjustable from 0.1-5000g), and dual-channel temperature control (independent upper/lower sealing knife temperature control) via the 10.1-inch touch screen.

Material Collaborative Processing
• Premade Bag Feeding: The rotating suction cup group, in coordination with the infrared positioning sensor, achieves a stable bag removal rate of 800-1200 bags/hour.
• Product Measurement: Utilizes a combined weighing system (linear error ≤±0.2g) and spiral volume measurement (powder accuracy ±0.5%).

Precision Filling Process
• Solid Materials: Equipped with an anti-bridging stirring device and dust removal vacuum system to handle granular materials ranging from 0.1-20mm in particle size.
• Liquid Materials: Utilizes a high-precision gear pump (flow repeatability ±0.3%) with an anti-drip nozzle, suitable for a viscosity range of 1-5000cps.

Sealing Quality Control
• Longitudinal Sealing: Utilizes a ceramic heating plate with PID temperature control to form a 3-5mm sealing belt (peel strength ≥35N/15mm).
• Horizontal Slitting: Employs a hydraulically driven shearing knife group to achieve burr-free sealing at a rate of 50-120 packs/minute.

Finished Product Output Management
• Quality Inspection: Incorporates integrated X-ray foreign body detection (sensitivity ≥0.3mm) and dynamic weight check (±0.1g resolution) for double-stage screening.
• Post-Processing: Features a modular output design with options for robot palletizing (up to 5kg load) or automatic box packing unit.
