Principle of Operation and Technical Guide for HFFS Horizontal Flow Wrapping Machine
Fundamental Operating Principle
Film Conveyance Mechanism
Upon unwinding the roll film through the guide roller, the servo drive system precisely transports it, maintaining a tension control accuracy of ±0.5.
A photoelectric sensor monitors the color mark, automatically correcting any stretching discrepancies in the printed material with an accuracy of ±0.3mm.
Formation and Product Insertion Stage
The forming mechanism molds the film to create a cylindrical structure for containing the product.
A synchronized conveyor gently introduces the product into the film cylinder with a speed deviation of less than 1%.
Heat Sealing and Cutting Component
The vertical sealing apparatus sustains a consistent temperature (adjustable from 150 to 200℃) to ensure a sealing strength of ≥4N/15mm.
The horizontal sealing cutter is equipped with dual temperature and pressure adjustments, enabling simultaneous cutting and end sealing.
